Problems solved by technology

Due to the high degree of automation, accuracy and timeliness of remote automatic meter reading, and it is also conducive to the management of the load by the power supply department, but the conventional wired meter reading system not only has high wiring costs, but also complicated wiring for dense users. Susceptible to interference from harmonic inrush currents in the power grid, resulting in increased meter reading costs, inaccurate measurement, and potential safety hazards

Embodiment Construction

[0022] Such as figure 1 As shown, a remote meter reading system, the overall structure of the remote meter reading system is divided from top to bottom: master station, concentrator, collection terminal and electric meter. The data of the electric meter is uploaded from the electric meter level by level. After the command of the master station is issued, the order is downloaded level by level, and the data is copied and uploaded level by level.

[0023] The master station is a computer system device with the function of selecting terminals and exchanging information with them. In the power acquisition control platform system, the main station includes four parts: front-end processor, application server, database server and acquisition control management software, while the front-end processor is the part that directly communicates with the terminal.

[0024] The concentrator is installed on the low-voltage side of the transformer in the station area to collect and store the d...

Abstract

The invention relates to a remote meter reading system, which adopts meter reading modules provided with electric energy metering chips; the voltage, the frequency, the active power, the power and the like can be measured, calculated and stored on the premise of inhibiting the harmonic waves and preventing the impact of overcurrent on the system; the data is processed under the control of a microprocessor and is then sent to a superior system. Meanwhile, respective meter reading modules form a sensor node for wireless networking, so that the integrated uploading of the data can be realized; the system maintenance, the fault overhaul and the expansion are easier. Finally, terminal electricity meter data is stored into a main database server; special system software is matched; the functions of automatic meter reading, data processing, information analysis statistics and the like are realized.

Description

technical field [0001] The invention relates to the technical field of electric energy metering of a power grid, in particular to a remote meter reading system. Background technique [0002] Remote automatic meter reading is to use modern computer technology and communication technology to automatically record the user's electricity consumption into the computer of the meter reading system, and the software performs statistical calculations. In the past, all the work of the meter reader was undertaken by the automatic meter reading system. Therefore, it is a new type of meter reading method that does not require personnel to go to the scene and has a higher degree of automation. The remote automatic meter reading system is composed of automatic meter reading device, communication media, computer local area network of power supply department business office and corresponding software. The communication media used for remote automatic meter reading mainly include low-voltage ...
