The device with a remote electricity meter data transmission
metering devices with remote transmission of information represent a device that converts analog signals into pulses, the counting of which is calculated, and the amount of electricity consumed. Differences electronic electricity meters from induction is not only the absence of moving mechanical parts. The main difference is the advanced functionality of the device, namely:
- increased time interval the input voltage;
- convenient organization of multi-rate metering system consumed electricity;
- the ability to view data on previous periods usernames;
- measuring power consumption;
- ability to connect to remote systems automatically collect and forward the information to the supplier.
In terms of design modern electronic counter is a housing in which is situated current transformer, terminal block and the printed circuit board, equipped with electronic elements scheme.
Note! An abundance of additional functionality is achieved thanks to a special software in the microcontroller unit of electricity accounting. These microcontrollers are equipped with almost all modern electricity meters.
The structure of electricity metering device, for remotely transmitting data
Current models of electronic type electricity meters include such binding elements:
- a liquid crystal display;
- timer, displaying the actual time;
- current transformer;
- output for connecting telemetry;
- monitoring and controls;
- power source for electronic Electric circuit;
- supervisor;
- optical port installed optionally.
A liquid crystal display is a multi-digit alphanumeric indicator to display operating modes metering device of electronic type. In addition, the LCD display shows the power consumed on the data, the actual time and date.
Independent power supply in the counter is intended to ensure the operation of an electronic circuit. To this is also connected a supervisor, which creates a reset signal to the microcontroller that occurs at power up or power failure. In addition, the supervisor enables to monitor changes in the input voltage.
The clock showing the actual time and date. In some models, this function is performed counters microcontroller. To reduce the load on a given part, tend to set a separate chip, which It reduces the power consumption of the microcontroller, redirecting vysvobozhdonnuyu energies to more important tasks.
Telemetry output of the counter - a connector for connecting the device to a PC, laptop or system data remotely. Optical port is set to read information directly from the device power account.
Attention! Optical ports are equipped with all models of electronic electricity meters. Some devices used for data programming.
microcontroller
The microcontroller is the most important element of the electricity meters with remote reading removal. On it is the implementation of the main part of the functions:
- input transform of the current transformer into digital information;
- data processing;
- output the resulting information on the LCD display;
- receiving commands from the controls;
- management interface.
The number and variety of functions directly related to the installed software. Currently, the metering devices are improved, adding new advanced features. Such functions include the possibility to monitor the state of the power supply and to transmit the received information to the control console electricity supplier.
Often manufacturers equip devices metering electrical power leveling function. In case of excess power consumption, the meter automatically interrupts access to the power supply. This was made possible thanks to the introduction in the contactor circuit, which controls the voltage supply to a household power source. Also, the device may shut off the electricity in case of exceeding the established limit, or if over prepayment for electricity supplied.
Control system
Automated data electricity metering control systems have been developed after the appearance of microprocessors. These devices were expensive and installed only in large industrial plants. Only thanks to widespread adoption of electronic meters and PC, as well as the appearance of cellular communication, wireless automatic metering have been developed.
On the automated system shall have the following tasks:
- gathering data about the electricity flows in the optimum time intervals for all voltage levels;
- analysis of the obtained information;
- creating reports based on the data provided or received power;
- analysis and forecasting electricity consumption;
- processing of payment data;
- implementation of calculations for energy.
Data transmission system according to meters
For the organization of the automated metering devices Data collection systems need to perform a series of mandatory measures. Firstly, it is necessary to perform the installation of high-precision equipment for metering of electricity. Next you need to download the data in a digital format in a special unit with built-in memory, which are called "adder and".
After performing the foregoing action created data transmission system (internet, GSM). The final stage is the formation of the center of the received information and a complete set of personal computers with the appropriate software.
Note! Modern electronic meters in most cases have a built-in interface for connection to automated data accounting system.
How do the electricity metering devices with remote reading
The most simple automated data systems perform the following functions:
- data collection;
- transmission of information to the service provider;
- analysis and subsequent storage.
To collect data using special devices that measurements of system parameters, including power metering devices. Among such devices can include various sensors that are connected to an automated system with with analogue and digital converters, or equipped with an input adapted for connection interface.
Further, in effect microcontrollers transmitting analog or digital signal interface between the different lines. It is necessary to collect the data controller or PC. At the final step is switched to the work server, a personal computer and the controller directly, which is the collection, processing and storage of information. To perform these functions, the system must have the appropriate software.
Automated Information System
For remote data transmission devices of the account can be used not only to electronic devices. Induction devices labeled "D" may be equipped with a special output for connecting telemetry. In principle, such output is a pulse generator, which occurs due to transmission of data to the system, the collection, processing and storage of information on the consumption electricity.
Measuring transformer produces pulses which emits magnetic flows crossing the aluminum disk. Further pulses are transmitted to an electronic sensor circuit and then fed to the communication line, feeding the device. The sensor has a photoLED head by a pair of light and photodiode. The sensor is positioned so that the head is always looking towards the aluminum disk. The LED emits light, reflected disc and received by a photodiode. Darkened disk sector is responsible for discontinuous signal received.
These interrupt signals are processed electronic circuit device, tested transformation into pulses and fed directly to the communication line. Further, they arrive at the receiving device, the number is counted for a certain amount of time and is reflected on the liquid crystal display.
Transmission of electricity meter readings
The data from electricity meters are sent to the service provider without the direct involvement of consumers and energy companies. The consumer must send only the first reading of metering devices. data transmission is performed as long as the provider does not tell you that this is no longer necessary.
Electricity consumption is performed every hour and forwarded provider once a day. There are models of electricity meters with SIM cards, through which the power company and the data is sending.
The benefit of electricity meters with automatic data transmission
The above scheme the remote data transmission by means of induction meter is quite possible, but in practice it is almost never used. Such devices are gradually being replaced by electronic device type, since they are most suited for use in automated transmission systems.
The disadvantages of electric meters with radio module should include the need for a permanent connection to the network, and in long-term absence of the place of residence can not be used to turn off the fuse metering device. For this purpose, a special cutter, but it is necessary to conduct additional wiring work, and the rest use counters with automatic data transmission promises a large number of benefits to consumer.
