Document Type and Number:
WIPO Patent Application WO/2024/098779
Kind Code:
A1
Abstract:
A safe power utilization system suitable for remote energy-saving management in tunnel construction comprises: a main control board which is electrically connected to a network port, a DB9 reservation, a debug port and RS232; an I/O board which is electrically connected to DB37 and redundant power supplies; and an LCU which is electrically connected to RS232; and a transmitter of a PLC control cabinet being arranged inside a tunnel. A control system comprises two control modes, i.e., a manual control mode and an automatic control mode; in the manual control mode, a valve and a power supply switch in the system can be opened or closed at will and a fan in the system can be started or stopped at will; and in the automatic control mode, the system can automatically run according to a set program. A tunnel ventilation system is used for detecting a manual/automatic state, operation and fault of the fan and controlling the fan to stop, and can detect air quality, and trigger an alarm bell when the regional air quality/CO/CH4 content exceeds a set value.
