A power grid terminal communication system

Abstract

The invention discloses a power grid terminal communication system, which comprises a sequentially connected power consumption terminal, an information collection module, a local centralized processor, a GPRS module and a remote monitoring center, the information collection module collects data information of the power consumption terminal, And gather the data information of the electric terminal into the local centralized processor, establish a connection with the GPRS network through the GPRS module, and transmit the data information to the remote monitoring center; the remote monitoring The center analyzes and processes the data information transmitted by the power consumption terminal, and then sends the control instruction back to the corresponding power consumption terminal. Therefore, the power grid terminal communication system described in the present invention can realize a high-speed, two-way, real-time and integrated power grid communication system.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a power grid terminal communication system. Background technique [0002] At present, the communication methods of the power grid automation system are all based on specific situations, using different communication technologies. At present, optical fiber, wireless, and low-voltage carrier are mainly used. The remote communication of the user's electricity information collection system mostly uses GPRS / CDMA wireless public network communication, 230MHz wireless private network and xPON technology. The local communication method uses low-voltage power line carrier, Short distance wireless communication, RS485 and other communication methods. [0003] The power wireless private network mainly uses low- and medium-frequency bands such as 230MHz to realize data collection and load control of power grid users. The wireless public network mainly uses the operator's public network...
