Abstract

The invention relates to a control circuit of a smoke exhaust fan and a smoke exhaust control system. The control circuit of the smoke exhaust fan comprises a signal access module and a smoke exhaustfan power supply control module. The first end of the signal access module is connected with the first end of the smoke exhaust fan power supply control module, and the second end of the signal accessmodule is used for being connected with a positive electrode of a power source. The second end of the smoke exhaust fan power supply control module is used for being connected with a negative electrode of the power source. The signal access module is switched on when a fire alarm signal is received, so that a power supply loop of the smoke exhaust fan is switched on by the smoke exhaust fan powersupply control module based on electric energy of the power source. The fire alarm signal comprises a smoke exhaust valve switch-on signal sent by a smoke exhaust valve, and an automatic remote startsignal sent by an automatic fire alarming system or an artificial remote start signal sent by a fire alarm linkage control system. By means of the control circuit of the smoke exhaust fan and the smoke exhaust control system, the problem that the smoke exhaust fan cannot be started when the automatic fire alarming system and the fire alarm linkage control system break down can be avoided, and then the reliability of the smoke exhaust fan is improved.
