Communication device and communication system

Abstract

The invention discloses a communication device. First serial data sent by a first electronic device located in an area with poor GPRS signals is received and sent to a control module through a serial port communication module, the control module converts the first serial data into second serial data and then sends the second serial data to a wireless private network communication module, and the wireless private network communication module receives the second serial data sent by the control module, converts the second serial data into analog signals, and then sends the analog signals through a wireless private network communication channel. The communication device of the corresponding receiving terminal can receive data through the wireless private network communication channel and send the data to a second electronic device located in a range covered by the GPRS signals through the serial port communication module, data information of the first electronic device has access to a GPRS network through the second electronic device, and therefore data communication in the area with the poor GPRS signals is achieved. The invention further provides a communication system.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a communication device and a communication system. Background technique [0002] In recent years, with the rapid advancement and development of smart grids, the scale of power grids has become larger and larger, and the requirements for automated operation levels have become higher and higher, especially for distribution automation, load management automation, power collection automation and power Scheduling automation and so on have put forward higher requirements. In these automation systems, data communication is an important technical support and one of the keys to realize the automation of power systems. [0003] GPRS technology has notable features such as simple networking, flexibility, convenient access, and low operating costs. It can meet the application requirements of power production in terms of real-time performance, reliability, and security...

Problems solved by technology

[0004] However, due to the wide distribution of power systems and equipment, some are located in remote areas, such as desert areas, remote mountainous areas or basements of urban buildings, etc., GPRS signal is not covered or the signal is weak, and some isolated points cannot communicate, such as Concentrators installed in the basement, assessment tables for station areas, and load management terminals and gateway meters without GPRS signal coverage in remote mountainous areas. The communication problems of these key equipment are difficult to solve, which has a great impact on the production and management of the power system. Increased the cost of manpower and material resources for power companies
