s1: the temperature sensing device 83 acquires the temperature in the test chamber and outputs a temperature signal;
s2: the monitoring device 82 generates a control signal;
s3: the controller 81 determines whether to unlock the electromagnetic lock 3 based on the temperature signal and the control signal.
The temperature sensing device 83 and the monitoring device 82 output a temperature signal and a control signal to the controller 81, respectively, and the controller 81 determines whether to unlock the electromagnetic lock 3 according to the temperature signal and the control signal. By the control method, test interruption and even safety accidents caused by mistaken unlocking of the mechanical lock 4 by personnel can be effectively prevented, and personal safety and test progress of operators are guaranteed.
Specifically, step S2: the monitoring device 82 generates the control signal including:
s202: the monitoring device 82 monitors whether the mechanical lock 4 has an opening operation, outputs a third control signal when the monitoring device 82 monitors that the mechanical lock 4 has the opening operation, and outputs a fourth control signal when the monitoring device 82 monitors that the mechanical lock 4 has no opening operation.
And step S3: the controller 81 judges whether to unlock the electromagnetic lock 3 according to the temperature signal and the control signal includes:
s302: when the control signal is the third control signal and the temperature signal reaches the preset range, the electromagnetic lock 3 is controlled to be opened, and when the control signal is the fourth control signal or the temperature signal exceeds the preset range, the electromagnetic lock 3 is controlled to be closed.
That is, when the operator opens the mechanical lock 4, the monitoring device 82 monitors the opening operation of the mechanical lock 4 and outputs a third control signal to the controller 81, and when the temperature in the test chamber reaches the opening condition of the door 2, the controller 81 controls the electromagnetic lock 3 to open, that is, the door 2 can be opened. And when the operator does not operate the mechanical lock 4, or the operator opens the mechanical lock 4, but the temperature in the test chamber does not reach the opening condition of the box door 2, the controller 81 controls the electromagnetic lock 3 to close, that is, the box door 2 cannot be opened. Through the operation, the situation that the mechanical lock 4 is opened by mistake by an operator to open the box door 2 can be avoided, but the temperature in the test cavity is too high or too low to cause scalding or frostbite, and the operation safety is improved.
