acquiring an alarm cancellation signal;
and stopping executing the second fire-fighting instruction based on the alarm cancellation signal. And timely manual cancellation of fire control processing under the conditions of false alarm and false touch is realized, and certainly, if an alarm cancellation signal is not received, the second fire control instruction is continuously executed.
As an example, after step S1053, the method further comprises:
detecting whether the operation of manually starting a fire control system is successfully executed;
if the manual starting of the fire control system is executed, the fire control system starts countdown automatically, the fire control system starts countdown, the countdown is started within the preset time, specifically, the first fire extinguishing device is started, and meanwhile, the charging cabinet is controlled to be powered off and the servo motor is controlled to transfer the target battery to the fire water tank. The method can determine whether the manual start of the fire control system is successfully executed by detecting whether the signal for manually starting the fire control system is successfully transmitted or detecting whether the fire control system successfully receives the start signal, and the like, and is not limited herein.
