The pressure sensor is simple and easy to obtain, has high detection precision, and can sensitively detect the action of the mechanical lock 4 so as to feed back the action to the controller 81. 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 meanwhile, when the temperature in the test chamber reaches the opening condition of the door 2, the controller 81 controls the electromagnetic lock 3 to be opened, i.e. the door 2 can be opened. When the operator does not operate to unlock the mechanical lock 4, or the operator unlocks the mechanical lock 4, but the temperature in the test chamber does not reach the opening condition of the door 2, the controller 81 controls the electromagnetic lock 3 to be closed, i.e., the door 2 cannot be opened. Through the operation, the door 2 can be prevented from being opened due to the fact that an operator opens the mechanical lock 4 by mistake, but scalding or frostbite is caused due to the fact that the temperature in the test cavity is too high or too low, and operation safety is improved.
Specifically, as shown in fig. 1 and 2, the mechanical lock 4 includes a first connecting body 41 and a second connecting body 42, the first connecting body 41 and the second connecting body 42 being provided on the cabinet 1 and the door 2, respectively, the first connecting body 41 and the second connecting body 42 being capable of being connected to or disconnected from each other. Illustratively, the first connector 41 is a lock pin, the lock pin is disposed on the case 1, the second connector 42 is a pin seat, the pin seat is disposed on the case door 2, and the case door 2 and the case 1 are closed or opened by inserting the lock pin into the pin seat, which is simple in structure and convenient to operate. In this embodiment, the pressure sensor may be disposed on the lock pin or on the pin holder, and when the lock pin is inserted into the pin holder, the pressure sensor outputs a fourth control signal, and conversely, the pressure sensor outputs a third control signal. The pressure sensor may be, but is not limited to, a pressure sensor, and when the first connector 41 and the second connector 42 are connected, the pressure sensor receives force and outputs a fourth control signal, and otherwise, outputs a third control signal. Preferably, the mechanical lock 4 further comprises a handle 43, wherein the handle 43 is connected to the second connector 42 or the first connector 41, for example, the handle 43 is connected to the lock pin, and the lock is achieved by rotating the handle 43 or pushing the handle 43 to drive the lock pin to insert into the pin seat. The door lock system of the environmental test chamber provided in this embodiment has the same structure as the other structures in the first embodiment, and will not be described in detail here.
As shown in fig. 5, this embodiment further provides a method for controlling an environmental test door lock, which is implemented by the above environmental test door lock system, including the following steps:
s1: the temperature sensing device 83 acquires the temperature in the test cavity 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 sensor 83 and the monitor 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, the test interruption and even safety accidents caused by the fact that a person mistakenly opens the mechanical lock 4 can be effectively prevented, and the personal safety and the test progress of the operator are ensured.
Specifically, step S2: the monitoring device 82 generates control signals including:
s202: the monitoring device 82 monitors whether the mechanical lock 4 has an opening operation, and when the monitoring device 82 monitors that the mechanical lock 4 has an opening operation, outputs a third control signal, and when the monitoring device 82 monitors that the mechanical lock 4 has no opening operation, outputs a fourth control signal.
Step S3: the controller 81 judging whether to unlock the electromagnetic lock 3 based on 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 at the same time, when the temperature in the test chamber reaches the opening condition of the door 2, the controller 81 controls the electromagnetic lock 3 to be opened, that is, the door 2 can be opened. When the operator does not operate to unlock the mechanical lock 4, or the operator unlocks the mechanical lock 4, but the temperature in the test chamber does not reach the opening condition of the door 2, the controller 81 controls the electromagnetic lock 3 to be closed, i.e., the door 2 cannot be opened. Through the operation, the door 2 can be prevented from being opened due to the fact that an operator opens the mechanical lock 4 by mistake, but scalding or frostbite is caused due to the fact that the temperature in the test cavity is too high or too low, and operation safety is improved.
