Problems solved by technology

[0006] The PLC solution in the application of the prior art uses a low-frequency carrier serial control signal. The signal transmission bandwidth of the low-frequency carrier is very small, and only a small number of terminal units can be connected, and the amount of transmitted data is greatly limited; the power carrier signal concentrator Using serial signal communication (such as I2C, SPI, etc.) with each terminal has two disadvantages: one is that the concentrator addresses the terminal unit.

Abstract

The invention relates to a communication device on the basis of a power line and a GPRS (General Packet Radio Service), which is characterized by comprising a communication head end, a communication terminal and a GPRS wireless terminal, wherein the communication head end is communicated with the GPRS wireless terminal through a first serial interface; and the communication head end carries out Ethernet communication with the communication terminal through the power line. The GPRS wireless terminal, the communication head end and the communication terminal are combined to form a complete remote wireless multipoint Ethernet transmission control platform. The communication device has the characteristics of large data bandwidth and high transmission reliability, so that the communication device is suitable for application to monitoring various power networks or industrial control and the like.

Description

technical field [0001] The invention relates to the technical field of electrical communication, in particular to a communication device based on power lines and GPRS. Background technique [0002] With the rapid development of digital technology, the technical application of GPRS and PLC is quite mature. [0003] GPRS (General Packet Radio Service, General Packet Radio Service) is a wireless packet switching technology based on the second generation mobile communication system GSM, especially suitable for intermittent, bursty or frequent, small amount of data transmission, and also suitable for For occasional large data transfers. The transmission rate of GPRS can reach up to 171.2 kbps, and the average rate in practical applications is also as high as 53.6 kbps. GPRS provides connections between mobile users and data networks, and provides high-speed wireless interfaces and X. 25 servings. GPRS adopts data packet switching technology, each user can occupy multiple wire...
