Description

Technical Field

[0001] The present invention relates to the technical field of cabinet temperature control switch testing, and in particular to a cabinet temperature control switch testing device and method. Background Art

[0002] A cabinet temperature control switch is a device used to control the temperature inside a cabinet. It typically consists of a temperature sensor and a control circuit. The temperature sensor detects the temperature inside the cabinet and transmits the temperature signal to the control circuit. The control circuit then controls the heating or cooling device within the cabinet within a preset temperature range. To test the switch, connect it to the heating device. Adjust the temperature control switch's knob or button to set different temperature settings. Observe the switch's operation near the set temperature to confirm that it switches accurately at the set temperature.

[0003] The existing temperature control switch test is manual. During the test, the cabinet temperature control switch must be connected to a 220V AC power source and a multimeter. The power switch is then turned on, and the heating device heats the cabinet temperature control switch. The multimeter readings are then recorded on paper. The existing solution has the following drawbacks: 1. Risk of electric shock: If the test operator accidentally touches any part carrying 220V AC power, such as exposed wires or terminals, during operation, an electric shock accident may occur. The current passing through the human body may cause electric shock injuries or even endanger life. 2. Risk of burns: If the operator accidentally touches the surface of a running heating device, he or she may be burned by the high temperature. For example, the temperature of heating tubes and heating plates can reach hundreds of degrees or even higher during operation. Direct contact can cause severe skin burns. 3. Fire risk: If the temperature set by the operator is too high, the heating device may overheat and cause a fire. For example, if the operator forgets to turn off the heating device or the temperature controller malfunctions, the heating device may continue to heat, causing the temperature to rise continuously and eventually causing a fire. 4. Low testing efficiency: Operators need to adjust temperature settings one by one, start and shut down heating or cooling equipment, and use tools such as thermometers to monitor temperature. Each step relies on manual intervention, which slows down the testing process. Summary of the Invention

[0021] After connecting all components according to their corresponding relationships, the main controller 1 runs the test program, communicating with the heating structure 8, programmable power supply 4, digital acquisition module 2, and analog acquisition module 3 to complete the device self-test. The test procedures include AC fan fault detection and electric shock output, fan start / stop control, and the cabinet AC fan power supply function test.

Switching quantity acquisition module 2 measures the temperature alarm status of the cabinet temperature control switch, determining whether a temperature alarm signal has been detected and whether the countdown has ended. If the temperature alarm status indicates a temperature alarm signal, then a temperature alarm signal has been detected. If a temperature alarm signal has been detected or the countdown has ended, cyclic test is terminated. When switching quantity acquisition module 2 detects a temperature alarm signal or the countdown has ended, main controller 1 controls programmable power supply 4 to shut down its output and heating structure 8.
