The IO output interface is connected with the interfaces of any of the following devices: compressor 17, fan 18.

Second embodiment

Refer to fig. 2 and 3. The function test fixture is provided with relays with the same number as the output loops of the controller 11, used for strong and weak current signal conversion, and provided with relevant resistors and a switch for entering a self-judging production mode.

The dehumidifier 10 controller 11 is provided with a voltage stabilizing circuit, an MCU (micro controller unit 12), a relay output loop, a sensor input interface, a digital display screen and an interface for entering a self-judging production mode, when production detection is carried out, a corresponding relay coil on a function test fixture is connected with the relay output interface of the controller 11, a corresponding relay contact on the function test fixture is connected with the sensor input interface of the controller 11, a reference figure 2 is connected with an input loop of a switching signal, and a reference figure 3 is connected with an input loop of an analog signal. The switch for entering the self-judging production mode on the functional test fixture is connected with the interface (the test reservation interface of the dehumidifier 10) for the controller 11 to enter the self-judging production mode.

The MCU of the controller 11 is programmed with a self-judging production test mode, and switches on a switch for entering the self-judging production mode. The controller 11 enters into a self-judging production test mode, automatically outputs each output loop one by one, drives a corresponding relay on the function test fixture to enable a contact of the relay to act, and connects signals of a sensor input interface of the controller 11. The controller 11MCU automatically determines the states of the output and input loops by detecting the state of the input loop signal, and the display screen (such as a digital screen) simultaneously displays the current testing procedure and state information. When the MCU judges that the current loop is normal, the process is automatically repeated, the other group of output and input loops are detected, and the digital screen simultaneously displays new testing steps and state information. And when all the steps are detected and passed, the digital screen displays the information that the test is passed. If the detection result of a certain group of loops is abnormal in the automatic detection process, the controller 11 automatically stops at the current step, and the digital screen always displays the current step number. The detection result can be only by checking the state information on the digital display screen, and the testing process does not need manual intervention. The display 19 for fault diagnosis result feedback may be shared with the display panel of the dehumidifier 10 or provided at the test fixture 20.
