摘要
目前,我国进行电力机车动力学实验时,传统的做法是采用有线电缆传输视频信号。为改进信号传输质量,本文提出了一种采用无线通信技术开发的动力试验车图像传输控制系统。该系统可以对远端摄像机和云台进行无线控制,同时具有音频双向无线传输的功能。实际应用结果表明,该系统运行稳定可靠,具有一定的实用性和推广价值。
Adopting cable to transmit video signal is the traditional method used in electric locomotive dynamics testing in China. In order to improve signal transmission quality, this paper introduced a picture transmission and control system, which was developed based on the wireless communications technology. The system can control the camera lens and rotational station remotely and also ensure bidirectional wireless transmission of audio signal. The results of the practical application show that the system operates stably and credibly, and has some value to apply and spread.
