Embodiment 1
[0039] This embodiment provides an intelligent detection system for an LED control device, such as figure 2 , including an oven, the LED control device to be tested is located in the oven, the intelligent detection system also includes at least one fixed temperature detection unit located in the oven, and at least one mobile temperature detection unit located in the housing of the LED control device to be tested , connected with the micro-control unit connected with the first temperature detection unit and the second temperature detection unit, and connected with the host computer of the micro-control unit; the fixed temperature detection unit is used to detect and feedback the ambient temperature in the oven; the mobile The type temperature detection unit is used to detect the temperature of the corresponding position of the housing of the LED control device to be tested.
[0040] Such as figure 1 , a schematic diagram of the temperature rise trend of the LED control device...
Embodiment 2
[0063] In this embodiment, the intelligent detection system is used for the current fault test of the thermal protector. Wherein, the intelligent detection system includes a current detection unit connected between the control device to be tested and the micro control unit. The current detection unit is used to detect the currents of the LED control device to be tested.
[0064] Control each output of the LED control device through the industrial control unit.
[0065] The test process is:
[0066] Except that the second step is to enter the upper limit temperature value in the fault state setting button dialog box, that is, the maximum temperature nominal value, the rest of the steps are the same as in the first embodiment.
[0067] The change of the input current of the LED control device to be tested is used to determine the action time of the thermal protector. Before and after the action of the thermal protector, the system will automatically monitor whether the maximum...
Embodiment 3
[0069] In this embodiment, on the basis of Embodiment 1, transformer heating is measured. The LED control device to be tested is protected from being placed in an oven under normal conditions and can make the case temperature reach ( ) °C ambient temperature and reach thermal equilibrium.
[0070] The process is:
[0071] Step (3) in Example 1 is changed to arrange a mobile temperature detection device at the winding of the test sample, which is a thermocouple in this embodiment, and measure the temperature rise of the winding of the sample under normal and abnormal working conditions. The temperature rise limit of the winding is preset, and the rest of the steps are the same as in Embodiment 1.
[0072] Abnormal state: Use the following test at any voltage of 90% to 110% of the rated power supply voltage for inspection: all should be applied to the LED control device under test for 1h.
[0073] In this embodiment, the industrial control unit is used to control the outpu...
