| Summary: | In order to improve the redundancy and anti-interference performance of locomotive short range wireless coupling control system, this paper proposes a design of locomotive short range wireless coupling control system based on Ad Hoc network technology. WTB bus data, key digital signal and voice signal are transmitted through the established wireless channel, so that multiple locomotives are controlled synchronously. The system makes use of the self-convergence characteristics of Ad Hoc network technology, which can furtherly improve the redundancy of locomotive short range wireless coupling control system without additional equipments. At the same time, through automatic frequency hopping, it selects channels with better SNR and CQI for communication, which improves the anti-interference performance of the system. Experimental results show that the SNR of the system is improved by about 5 dB compared to that of the systems based on WiFi modules, and the packet loss rate is reduced from 0.029 2% to 0.010 9%. |
