What is the pipe gallery? The integrated pipe corridor is a comprehensive corridor of underground city pipelines, that is, a tunnel space is built underground in the city, and various engineering pipelines such as electric power, communication, gas, heat supply, water supply and drainage are integrated into one, and a special inspection port and lifting port are provided. And the monitoring system, the implementation of unified planning, unified design, unified construction and management, is an important infrastructure and "lifeline" to ensure urban operation.
In the regulations, there should be a fixed communication system in the pipe gallery, and there is no special requirement on the performance requirements. It seems to be a dispensable device, and because of the special structure of the pipe gallery transmission distance, the ordinary analog phone It is impossible to solve the communication in the pipe corridor, so most of them adopt the mode of optical fiber transmission, thereby solving the problem of long transmission distance.
