With the introduction of the law on the independent transfer of data on the resources consumed by the management company, residents were faced with the need to monthly rewrite the readings of electric meters (as well as other metering devices), call or personally visit the offices of service organizations. But it happens that there is no time for this or a person forgot to transfer the data. Then, without paying a penny, you will have to deposit double the amount next month, which is inconvenient when the budget is calculated. However, this will not happen if you install an electric meter that transmits readings to the management company on its own. Today we will talk about the pros and cons, as well as the design of such equipment.

Features of electricity meters with remote reading

The difference between transmitting electricity meters and simple ones is the presence of a microcontroller and a data transmission system that enable energy sales companies to remotely monitor energy consumption and even turn off its supply to the apartment in case of non-payment. To transfer the readings of the electricity meter, no action is required from the owner - only the initial setup and transmission of the first readings.

Functions of the information-measuring system

The task of the information-measuring system is to collect, analyze and transfer information about electricity consumption to a supplier or a controlling organization. It provides the ability to turn off or resume the supply of electricity by the supplier, or even limit the power, if the consumer exceeds the limit under the contract.

Interesting information! With the help of the analysis made by the information-measuring system, it independently warns the consumer by sending informational messages to e-mail or personal account on the company's website.

Advantages of electric meters with remote reading

Electric meters with remote reading have a number of advantages over conventional devices. Let's consider some of them:

1. Daily data capture allows you to resolve disputable situations - if there are questions about accruals.
2. Instant fixation of tariff switching. In the case of conventional multi-tariff meters, there are situations of untimely switching. In this case, the power supply company resolves disputes not in favor of the owner.
3. Additional protection. Often the owner forgets to turn off the iron or electric stoves, remembering this at work or on a trip. Using an electricity meter with data transfer, you can turn off the power supply from anywhere using a smartphone or computer connected to the Internet. Agree, a good way to protect your home.
4. Saves time. Recording readings, wasting time on data transfer - today this is a luxury in our rhythm of life.

Electricity meter device with automatic data transmission

The device of such electric meters is similar to conventional ones and includes:

• measuring transformers;
• terminal block;
• electronic board.

The latter is designed to connect the information-measuring system. But on the device it is worth dwelling in more detail. Let's see what it consists of.

Telemetry output: purpose

The telemetric output of the meter is a kind of port through which the meter is connected to a personal computer or remote data transmission equipment. Today, the manufacturer even offers analog devices equipped with a telemetry output, and hence the possibility of automatic data transfer.

Microcontroller: what is it and what is it used for

This device digitizes the input signal coming from the transformer, processes the information and receives commands from the controls. The operation of the liquid crystal display also depends on it.

Expert opinion

Engineer-designer of ES, EM, EO (power supply, electrical equipment, interior lighting) ASP North-West LLC

“The microcontroller limits the power of the current that is supplied to the apartment or completely turns off the voltage upon reaching the paid threshold, even without a command via the Internet. This happens if, under an agreement with an energy retail company, the supply of electricity is limited.”

There are models whose microcontroller is responsible for reading data from plastic smart cards that can be replenished from a regular bank card (for example, STK-3-10 or STK-1-10). An electric meter equipped with a similar controller makes it possible to pay for electricity instantly without leaving home.

Control system: principle of operation

Automated control systems perform the following functions:

• collect data on consumption for a specified period of time (hour, day, week, month);
• after processing the received information, they form a report on the consumed energy;
• predict a possible expense (this helps the consumer if an agreement is drawn up for a prepaid calculation system).

The exchange of information between the meter and the electricity supplier takes place using a data transmission system. It depends on its functionality and the functions programmed in the microcontroller whether the device itself will transmit information about the consumed electricity or the owner will have to press the button of the power transmission device on certain days to remotely read the electricity meter.

Radio module: what is it for and what role does it play

Not all electricity meters are equipped with a radio module. Such devices are more often used by service organizations to take readings from general house electricity meters. Two-way communication is carried out over the radio channel. Interfacing range up to 10 kilometers. Otherwise, an electric meter with a radio module does not differ from those that work via the Internet via a wired connection, Wi-Fi or electricity meters with a SIM card that communicate through a mobile operator.

In this review, we will consider the types of structures, what you need to pay attention to when choosing, popular models and manufacturers, average prices, recommendations from experts.

Such devices instantly transmit information about an opening attempt, a short circuit or other emergency situations. Like metering devices that transmit data via the Internet, they are equipped with a battery for autonomous power supply, which means that information about the shutdown and all subsequent actions will be displayed on the computer of the controlling organization.

How does an electric meter that transmits readings work?

The main work takes place in three stages - consumption data is collected, sent to the server of the energy sales or controlling organization, analyzed and archived. The first stage is performed by sensors that collect data on electricity consumption, and control over their operation and processing of the information received is carried out by the electronics of the metering device. There can be no more than 32 such sensors - the receiver is designed for such a maximum number.

Further, the data is transferred for storage to the server, where they can be viewed in real time from your home computer or from any other point by logging into your personal account. This work is assigned to the controllers that transport the signal. They also display data on the liquid crystal display of the electricity meter.

The third stage is data archiving and analysis on the server, controller and PC. At the same time, special software must be installed on the computer, which will allow processing the information received. If such software is not available on your home PC, you can view the data only in your personal account on the website of the company exercising control.

Automatic transmission of data on electricity meters

Automatic transmission of electricity meter readings is carried out by a controller programmed for a specific day of the month. It works in tandem with a server that organizes the received data. The transfer is carried out via the Internet or via mobile communications. To transport data over a cellular network, a SIM card is installed in a special slot of the metering device.

How to transfer data on meters with an automated system

Electric meters with the transfer of readings require minimal human participation in the process. You only need to press a button once a month, and the data from the meter has already been sent to the right address. However, automated sending of meter readings is even more convenient. The owner sends data to the server only once on his own. Subsequently, the controller itself performs this work. Here's how it goes.

After installing the equipment, the consumer transmits the indicator by pressing the button of the automatic data transfer device or directly on the site. Sometimes the readings need to be sent only once, sometimes several, every 5-10 minutes. These actions are performed before receiving a message from the energy retailer or controlling company that the data has been received. From this moment on, no action can be taken - all information will be sent to the desired address automatically. The electricity meter archives the data every hour, and sends them once a day.

How an induction electricity meter with automatic data transfer works

Induction metering devices with the ability to connect equipment for transmitting meter readings are marked with the letter "D". They have a telemetry output for connecting a controller. Reading information is as follows.

The inductor emits electromagnetic waves, causing the aluminum disk to rotate, under which the pulse sensor is located. Its circuit includes a system consisting of a photo and LED. The system is located so that the LED beam, reflected from the aluminum disk, falls on the photodiode. The disk has an absorbing band of light. Thus, an interrupt is provided, which the electronic circuit fixes and transmits to the receiver. It counts the received pulses, after which the data is displayed.

The advantage of electronic meters with automatic data transmission over induction

Induction electricity meters with the ability to transmit readings lose to electronic ones in terms of the lack of additional options. This is especially true for remote power outages. The problem is the need for a constant connection to the network. When carrying out electrical installation work with the removal of voltage, data from the meter is no longer transmitted. This means that in case of unauthorized opening of the device to steal electricity, the server will not receive a signal about this.

Interesting! Despite the possibility of such a connection, such equipment is gradually changing to electronic meters with automatic data transmission.

Overview of manufacturers and prices for some models

The most famous and popular brand among manufacturers of equipment for automatic transmission of meter readings is « Mercury» . Models of this brand, their characteristics and cost as of January 2018 now and consider:

This can be useful for resolving disputes with a resource supply company, and simply makes it possible to quickly and easily get an answer to the question: "When did we manage to pour out so much water?" Graphs in your personal account show water consumption up to hourly data.

You no longer need to remember about the need and timing of the transfer of evidence

Just tell SAURES when and where to transfer data and the system will automatically do it for you. No more accruals according to the standard due to non-delivered testimony.

More reasons to install smart meters

No more climbing into a plumbing closet with a mirror and a flashlight or performing miracles of acrobatics

Sometimes counters are installed in hard-to-reach places, and sometimes installers surprise with their dislike for people by installing the counter with a dial on the wall. If taking a reading every month turns into an acrobatics act for you, then SAURES R1 is what you need. Now all the readings are on your smartphone and you do not need to climb into the plumbing cabinet.

This article discusses the features of such metering equipment as an electric meter that transmits readings: the specificity of devices, their design, advantages and disadvantages, the system for using devices with remote control, the scheme for transmitting readings on electrical energy consumption and the rules for performing this procedure in accordance with the requirements of regulatory authorities.

The electric meter that transmits readings allows you to automatically send data on the used kilowatts

Meters equipped with a remote reading system are suitable for apartment owners who do not want to think every month about how and where to transfer the received readings of the meter. If a consumer of electrical energy has a similar device installed at home, the data transfer will be carried out automatically without the direct participation of a person.

Sending twisted kilowatts does not take much time, and the process itself is comfortable and convenient. Electricity supply companies can use these devices to monitor the energy consumption of the population.

In a global sense, which are capable of transmitting information remotely, allow rationalizing the consumption of electricity and achieving efficient operation of the entire system, from energy production to its consumption and data processing for paying utility bills using network information and metering systems.

Note! Metering equipment with remote transmission of information differs from a standard electric meter by the ability to switch tariffs. When taking data, the user can see three indicators: night, total and day. In this case, the switching is carried out every 15 seconds.

Purpose of information-measuring systems

Network systems designed to collect measurement information on meter readings organize the process of remote data transmission from metering equipment via the worldwide Internet.
The operation of such systems is automated. Due to the software, the information is read and the received data is subsequently sent to the server of the energy supply company.

Information and measuring systems are used to automate the following processes:

• collection of information;
• data transfer;
• analysis of energy consumption indicators.

The use of information and measurement systems by energy supply companies not only gives them access to indicators on the consumption of electrical energy, but also provides a number of additional functions. This includes the following possibilities:

• operation of accounting equipment in the mode of several tariffs;
• connection or disconnection of the consumer of electricity in remote mode;
• individualization of work with the consumer of electric energy, taking into account the terms of the signed contract;
• forwarding warning notices;
• effective analysis of the collected information, etc.

Note! The feedback from the consumer to the energy supply company or service company via a data processing system is carried out using the Internet.

Benefits of automatic transmission of meter readings for users

By installing meters in your apartment that have the function of automatic remote data transmission, the homeowner receives many advantages.
Benefits of the system for users:

• resolution of disputes - meter readings can be recorded every day. Such a data transfer scheme eliminates conflict situations if there are problems with receipts or the transfer of information by the subscriber is not carried out regularly;
• control of readings - metering devices provide the ability to take readings from places that the consumer rarely visits, for example, from a rental apartment, garage or country house;
• high calculation accuracy during tariff switching - if there are no indications by the date of tariff change, energy companies make charges based on average indicators. As a rule, the settlement is carried out in favor of the supplier company. The use of metering devices with a remote transmission function avoids such problems;

A meter with an automatic counting system will be convenient for users who use several electricity metering tariffs

• remote control of the meter - the equipment can be used to preheat housing. It is enough to connect the device a couple of hours before coming home, so that the heater system warms up the premises before arrival. This will require a smartphone;
• safety - if the owner forgets to turn off an electrical appliance, for example, or a stove, there is no need to return home. It is enough to de-energize the apartment by remotely turning off the meter;
• practicality and time saving - the user does not need to spend time and effort on taking readings, queuing at the cash registers or transmitting information using standard methods.

Important! If bills are not paid, the company can remotely turn off electricity access to the apartment. To do this, employees do not even need to visit the debtor's apartment.

Device of meters for remote transmission of electricity readings

Equipment designed to measure electrical energy is a kind of converter that converts an analog signal into a pulse frequency. When these pulses are counted, the amount of electricity consumed is calculated.

If we compare electronic devices with induction-type devices, then the differences affect not only the internal structure, in which there are no mechanical rotating elements.

The main distinguishing feature is the advanced functionality:

• extended time interval for input voltage;
• convenient organization of multi-tariff accounting systems;
• the presence of a mode for viewing indicators for past periods (months);
• the ability to measure power consumption;
• Possibility of connection to systems of automatic data acquisition and transmission.

With regard to the structural structure, a modern electronic type meter is a housing frame equipped with a measuring current transformer, a terminal block, and a printed circuit board. The latter serves as the basis for mounting the electronic component of the device.

Note! A large number of additional functions is due to the presence of software in the microcontroller of the device. Similar components are present in almost all electric meters of the modern generation.

The structure of electricity meters that transmit readings remotely

The design of a modern electronic type meter consists of the following elements:

• LCD display;
• clock displaying real time;
• current transformer;
• telemetric output;
• bodies exercising control and management;
• a power source designed to service the electronic circuit;
• supervisor
• optical port, which can be installed optionally.

The LCD display is a multi-digit type alphanumeric display. Its main function is to indicate the operating modes of the counter. In addition, the component displays information about the consumed electrical energy, the current time, and the date.

The power supply provides voltage to the microcontroller and other components installed in the electronic circuit. A supervisor is connected directly to it, which generates a reset signal for the microcontroller that occurs when the power is turned off or on. In addition, the supervisor monitors input voltage changes.

Real time clocks are used to accurately keep track of the date and current time. In some modifications of the meters, a microcontroller performs this option. In order to reduce the load on this part, most often a separate microcircuit is provided for such purposes. It saves microcontroller power consumption by directing this energy to more important tasks.

Using the telemetric output, the meter is connected to a personal computer or a remote data transmission system. The optical port is designed to take readings directly from the accounting device.

Note! The optical port is not present in all devices. In some models, it is involved in programming information.

Microcontroller and functions of devices with remote transmission of electricity readings

The most important part of the device is the microcontroller. It performs most of the functions:

• converting the input signal coming from the current transformer into digital data;
• mathematical processing of information;
• outputting the result to the display;
• receiving commands from governing bodies;
• interface management.

The list of microcontroller functions depends on the installed software. To date, active work is underway to improve such equipment, which consists in adding additional functions. These options include the ability to monitor the state of the power grid, while transmitting data to the dispatch center.

Often meters have a function that allows you to limit the power level of the network. If there is an excess of power consumption, the device automatically interrupts the consumer's access to the network. This system works by means of a contactor that controls the voltage supply. The device can also turn off if the consumer exceeds the assigned energy limit or runs out of prepaid electricity.

Note! Some modifications of electricity meters are equipped with readers that accept plastic cards. They are designed to replenish the balance. This category of devices includes models STK-3-10 and STK-1-10.

Control system in electricity meters with remote reading

Automated systems designed to control accounting data for electrical energy have been developed due to the emergence of microprocessors at an affordable cost. The price of these devices was relatively affordable, so only large enterprises in the industrial sector could afford the installation of such equipment.

With the invention of electronic meters and PCs, automated accounting systems have taken a significant step forward. Thanks to the introduction of cellular communications, wireless-type systems have been created.

Automated accounting systems perform the following functions:

• collection of electrical energy flows for a reasonable period of time at all voltage levels;
• processing of received information;
• generation of reports on released or consumed power (electrical energy);
• analysis and forecasting for generation (consumption);
• processing payment indicators;
• performance of calculations on electric energy.

To organize an automated accounting system, you need to perform the following steps:

1. Install high-precision accounting equipment. To do this, electronic meters are installed at electricity metering points.
2. Transfer digital information (signals) to blocks with built-in memory. They are called "adders".
3. Form a communication system, for example, GSM. It will be used to transfer data.
4. Form data centers and equip them with computers with appropriate software.

Note! To date, many electronic type meters have a built-in interface for connecting an automated accounting system. Even those devices that do not provide such an option allow you to install an optical port designed to take readings locally.

How to transfer readings of electric meters with an automated system

The process of sending data is carried out without the participation of the subscriber. It is only responsible for transmitting the first indicator. This data must be reported until the manufacturer sends notice that it is no longer necessary. Measurement of electricity consumption in such meters is carried out every hour. Once a day, the information received is sent to the controlling organization. Some models use a mobile connection.

How do electricity meters work, transmitting readings automatically

The simplest automated data transmission systems carry out their work in stages:

1. Collection of information.
2. Data transport.
3. Analysis of the received information, its further storage.

The main participants in the first stage are the devices that measure the parameters of the system, and the electricity meters themselves. The category of measuring devices includes all kinds of sensors that are connected to the system via analog digital converters or equipped with an output used to connect the interface.

The interface line used to transmit the information signal has an input impedance of 12 ohms. Since the power capabilities of the transmitter are limited, similar restrictions are imposed on the number of receiver devices that are connected to this line. The maximum number of sensors for which the receiver is designed is 32 pcs.

Note! The automated system can be used not only on electronic, but also on induction meters in which a converter is installed. It converts the number of disc revolutions into electrical impulse signals.

At the second stage, the controllers come into operation, transporting the signal between the interface lines. This procedure is necessary for reading information by the controller or personal computer. If more than 32 sensors are involved in the connection, then concentrators are installed in the system.

At the third stage, a server, a PC and a controller are involved, which collect data, analyze them and save them. The system must have the appropriate software that allows you to configure it.

Induction type electricity meters and automatic data transmission systems

Not only electronic devices can be used to transmit indicators remotely. Induction devices marked with the letter "D" are equipped with a telemetry output. In fact, this output is a pulse sensor. The SRZU-I670D model can be attributed to the category of such devices. Due to the pulse sensor within the framework of a two-wire communication line, information is transmitted to the system that collects and processes data. The information contains data on the active electricity that passes through the device.

The pulse source is a measuring transformer. It radiates a magnetic flux that crosses a metal sector mounted on an aluminum disk axis. Next, these pulses are transmitted to the sensor circuit, and then to the communication line that feeds this sensor.

A photo-LED head is installed on the pulse sensor. It is a pair consisting of an LED and a photodiode. The sensor inside the electric meter has a specific location. The device is installed so that the head is turned towards the aluminum disk. The LED emits a signal that is reflected by the disc and then received by the photodiode. The darkened sector on the disc provides signal discontinuity.

These interrupts are monitored by the electronic circuit, converted and fed to the communication line in the form of a pulse train. Then the receiving device receives them, performs a count for a certain period of time and displays the result on the display.

Why are electronic meters beneficial when transmitting readings for light

Theoretically, the induction counter system described earlier is possible, but in practice it does not make sense. Such devices are gradually withdrawn from service and replaced by electronic ones. The exception is locally placed accounting equipment.

Electronic devices in relation to the creation of automated systems for the transmission of readings have significant advantages, which are determined by the information component and extensive service capabilities.

The disadvantages of such equipment include the need for a permanent connection to the network. When leaving for a long time, do not use the fuse to turn off the meter. There is a special switch for this. The exception is electrical work. Otherwise, the operation of electronic meters that independently transmit readings is accompanied by benefits for the user.
