Wireless Communication Technology In The Protection Equipment

With the development of communication and computer technology, people need better communication to each other. As a popular communication technology, wireless communication has attracted broad attention now. In several fields of industry, wireless communication technology is a new direction in the future. What this paper studied is a concrete application of wireless short distance communication technology in relay protection equipment.From analyses of the demand, the paper discussed the design of every module in detail after establishing the hardware. Then, it illuminates the method to design the antenna in the wireless communication module. After we have designed the all hardware modules, this paper described the software program flows in detail, the process of transceiver and how to build a wireless local area network. Finally, the paper introduces some methods about how to improve the quality and stability of communication system.This wireless module communicates with computer using serial interface and connect, to DSP with TX and RX pins. The experiment shows that this device is efficient, the distance and the speed of communication can satisfy the demand of this wireless system. However, the stability of this module should be further improved so that it will be available for the industrial market.
