摘　　要：随着现代安防技术的发展,大范围远程监控的应用越来越多,而远程监控中如何传输成为其主要问题.文中介绍了一种用于光纤传输的,基于CPLD(复杂可编程逻辑器件)的视频、音频等数据的远程传输设备的设计和实现.实验证明,该设计能够较好地完成远程传输任务,其监控图像清晰、数据准确,可以广泛应用于安防行业.With the development of technology for public security, the large-scale remote monitoring technology is used widespreadly in many fields, but the data transmission of long-distance is one of the main obstacles. The design and realization of a remote video/audio data transmission equipment using fiber optic transmission were introduced. A series of experiments prove that the method can complete the long-distance transmission very well. The received pictures are observed clearly and the received data are correct, so it can be used in many fields of public security.
