Through the arrangement, the control cabinet 20 to be tested can be tested simultaneously, and a plurality of ports of one control cabinet 20 to be tested can also be tested.
In this embodiment, when the test device 10 tests the control cabinet 20 to be tested, the multiple signal transmission ports include at least one first signal transmission port for signal output and at least one second signal transmission port for signal input, the control cabinet 20 to be tested is connected to the first signal transmission port and the second signal transmission port of the control module 12, and the control module 12 is further configured to obtain a test feedback signal generated by the control cabinet 20 to be tested based on the test signal simulation operation condition through the second signal transmission port, determine whether the control cabinet 20 to be tested is abnormal according to the test signal input to the control cabinet 20 to be tested and the test feedback signal fed back by the control cabinet 20 to be tested based on the test signal, and generate a prompt signal when the test signal is abnormal.

The control cabinet 20 to be tested may be a control cabinet having a plurality of interfaces, where the plurality of interfaces may be connected to components such as a source component or an actuator, so as to execute corresponding functions according to signals sent by the source component or the actuator, and the determining whether the control cabinet 20 to be tested is abnormal specifically is testing whether the control cabinet 20 to be tested is abnormal when executing corresponding functions based on signals sent by each source component or the actuator.
That is, when a plurality of functions of the control cabinet 20 to be tested need to be tested, that is, the control cabinet 20 to be tested includes an interface corresponding to each function, the plurality of first signal transmission ports for signal output of the test equipment 10 are provided, and each of the first signal transmission ports is connected to one interface corresponding to one function of the equipment to be tested.

The specific step of determining whether the control cabinet 20 to be tested is abnormal according to the test signal input to the control cabinet 20 to be tested and the test signal fed back by the control cabinet 20 to be tested based on the test signal may be:

Through the arrangement, whether the control cabinet 20 to be tested is abnormal or not can be accurately detected by using the test equipment 10.
In order to prompt a user to overhaul or check the control cabinet 20 to be tested when the control cabinet is abnormal, in this embodiment, the test device 10 further includes an alarm 16, the alarm 16 is electrically connected to the control module 12, and the control module 12 is further configured to control the alarm 16 to send an alarm signal when it is determined that the test device 10 is abnormal.

Taking the example that the fan in the control cabinet 20 to be tested can realize the air supply function when receiving the pressure difference signal of the fan sent by the external control device, when detecting the air supply function of the control cabinet 20 to be tested, three interfaces for transmitting the pressure difference signal, through which the control cabinet 20 to be tested realizes the air supply function, are respectively connected with three signal transmission ports of the control module 12, the test device 10 receives the control information input by the user and the port information of the three signal transmission ports, when the control information includes the fan pressure difference signal of the control cabinet 20 to be tested, the voltage values respectively corresponding to the three interfaces are obtained according to the pressure difference signal, and the three signal transmission ports of the test device 10 respectively send the voltages corresponding to the voltage values to trigger the fan to work, so as to simulate and detect the air supply function of the control cabinet 20 to be tested, and determining whether the air supply function of the control cabinet 20 to be tested is abnormal according to whether the fan in the control cabinet 20 to be tested supplies air normally.
Taking the example that the control cabinet 20 to be tested can be connected to a temperature/humidity sensor for implementing a temperature/humidity detection function, when the control cabinet 20 to be tested is used for implementing the temperature/humidity detection function, the control cabinet 20 to be tested needs to receive an electrical signal detected by the temperature/humidity sensor and obtain a corresponding temperature or humidity according to the electrical signal, where the electrical signal is a 4-20mA current signal. Therefore, the test device 10 can be used to output an electrical signal for simulating an electrical signal generated when the temperature/humidity sensor is in operation, so as to detect the temperature and humidity detection function of the control cabinet 20 to be tested. Specifically, the human-computer interaction device 14 may receive control information input by a user, where the control information may include a voltage value corresponding to a temperature/humidity value to be simulated or model information of a device to be simulated, and when receiving the voltage value, the control module 12 sends an electrical signal corresponding to the voltage value to the control cabinet 20 to be tested through a model transmission port for temperature/humidity grinding connected to the control module, so that the control cabinet 20 to be tested calculates the temperature/humidity value according to the current model, and the control module 12 may further determine whether the control cabinet 20 to be tested is abnormal according to the temperature/humidity value calculated by the control cabinet 20 to be tested and the temperature/humidity value to be simulated; or, when receiving the model information of the device, the control module 12 may search for a voltage value or a current value corresponding to the model information pair of the device from the preset corresponding relationship, it will be appreciated that when the device is a temperature device, the voltage or current values described above will correspond to a simulated temperature value, when the device is a humidity device, the voltage value or the current value corresponds to a simulated humidity value, and when the control module 12 obtains the voltage value or the current value, the current corresponding to the current value or the voltage corresponding to the voltage value is transmitted through the signal transmission port connected to the control cabinet 20 to be tested, so that the control cabinet 20 to be tested obtains the temperature/humidity value through calculation according to the obtained voltage or current, the control module 12 may also determine whether the control cabinet is abnormal according to the temperature/humidity value calculated by the control cabinet 20 to be tested and the simulated temperature/humidity value.
According to the above, by using the test equipment 10 of the present application, it is possible to input different analog signals to the control cabinet 20 to be tested, and the power supply of the control cabinet 20 to be tested is turned on to perform an analog test on the control cabinet 20 to be tested, and the output values of the current and the voltage of the analog signals can be adjusted by the human-computer interaction device 14 to simulate actual data detected in the actual working process of different source components, so as to accurately simulate the actual running condition of the control cabinet 20 to be tested, thereby detecting whether the quality and the function of the control cabinet 20 to be tested are qualified and meet the requirements and determining whether the control cabinet 20 to be tested is abnormal according to the actual running condition.
