研究了光纤通信在高压系统中的应用。根据所传输信号在系统中的作用,选择适当的信号调制方式对提高系统的安全性能和性价比都有重要意义。对于模拟量信号,一般采用PFM调制即V-F／F-V转换来实现精确传输。对于要求传输速度很快的信号,采用直接光强调制来实现快速传输。
The application of optical fiber communication in high voltage system is studied. According to the role of the transmitted signal in the system, it is of great significance to select the appropriate signal modulation method to improve the system security and cost performance. For analog signals, PFM modulation is generally used to achieve accurate V-F / F-V conversion. For signals requiring fast transmission, direct light intensity modulation is used to achieve fast transmission.
