The Research and Practice in Long Tunnel Fan Remote Control Technology

摘要

This paper represents a new long tunnel fan remote control system which is designed for the current shortcoming in tunnel construction by using manual control of the fan. This system has advantages of centralized control, automatic intelligent, strong compatibility, easy maintenance, long distance communications, and low environmental requirements. It has been successfully deployed in Chengdu Railway Yuelongmen tunnel and was compatible with tunnel hydrogen sulfide gas monitoring system docking, automatically adjusting the fan speed according to the hole concentration of hydrogen sulfide gas, achieving good economic effect and ensuring construction safety. The system represented in this paper is a solution to the Long Tunnel Ventilation centralized management of automated intelligence.
