| Abstract: | Train key equipment and wireless real-time monitoring of traffic state is effective technical support for the safe operation of trains. But how to extend the communication distance of the wireless monitoring node, and enhance communication reliability become a research focus. This paper presents a design method for the train to monitor the RF power amplifier module in the special environment .It can avoid internal interference by using the integrated chip RF5110G, Through the filter circuit and the design of impedance matching circuit board optimization, the designed power amplifier module solves train signal attenuation problems caused by special environment . At the same time it can enhance data transmission reliability of monitoring network node , which is a viable approach of the train monitoring and maintenance. |
