[0032] See also Figure 1-2The present invention provides a technical solution: an abnormal warning tester for electrical appliances and a method of use, comprising a test frame 1 and an air temperature processing device, wherein a test platform 2 is provided on the test frame 1 for placing manufactured electrical appliances, an operation panel 3 is provided on one side of the test frame 1 for connecting the electrical appliances, a temperature sensor 4 is fixed on one side of the test frame 1 for detecting the temperature in the workshop, and the air temperature processing equipment is evenly distributed in every corner of the workshop.

[0033] A method for using an abnormal warning tester for an electrical appliance comprises an abnormal warning test system for the electrical appliance. The abnormal warning test system for the electrical appliance comprises a test module, a judgment module and a terminal module. The test module comprises a voltage monitoring submodule, a temperature detection submodule and a time monitoring submodule. The voltage monitoring submodule is used to monitor the voltage of the electrical appliance during the test, the temperature monitoring submodule is used to monitor the temperature of the electrical appliance during the test, and the time monitoring submodule is used to monitor the duration of the electrical appliance test.

[0034] The judgment module includes a voltage analysis submodule, a temperature comparison submodule and a marking submodule. The voltage analysis submodule is used to analyze the voltage condition of the electrical appliance during the test. The temperature comparison submodule is electrically connected to the temperature sensor 4. The temperature comparison submodule is used to compare the temperature of the electrical appliance during the test with the workshop temperature. The marking submodule marks the electrical appliances with quality problems.

[0035] The terminal module includes an early warning submodule and an adjustment submodule. The early warning submodule is used for warning, and the adjustment submodule is electrically connected to the air temperature processing equipment to control the overall temperature of the workshop.

[0036] The electrical abnormal warning test system includes the following specific operation steps:

[0037] Step 1: Place the manufactured electrical appliance on the test platform 2, connect the electrical appliance to the operation panel 3 through the detection line, and turn on the current;

[0038] Step 2: When the electrical appliance is connected to the operation panel 3, the voltage is monitored by the voltage monitoring submodule to determine the voltage during the electrical appliance test;

[0039] Specifically, a normal constant voltage for the electrical appliance is set in the voltage monitoring submodule. If the voltage monitored in real time by the electronic monitoring submodule is within the constant voltage range, it means that the voltage of the electrical appliance is normal. If the voltage monitored in real time by the electronic monitoring submodule is not within the constant voltage range, it means that the voltage of the electrical appliance is abnormal.

[0040] Step 3: Monitor the time when the appliance is tested through the time monitoring submodule, and determine the voltage change frequency of the appliance through the voltage analysis submodule in combination with the voltage change magnitude.

[0041] Step 3 includes the following specific steps:

[0042] Step 3-a: When the voltage monitoring sub-module is working, the time monitoring sub-module starts to operate. Set the duration of the electrical appliance test in the time monitoring sub-module as t, where t is a constant value;

[0043] Further, when the voltage of the electrical appliance changes, the time monitoring sub-module starts to monitor the duration of the voltage change, and record the duration as p;

[0044] Step 3-b: The voltage analysis sub-module combines with the test time to judge the voltage change frequency of the electrical appliance, and marks it through the marking sub-module;

[0045] Specifically, judge the duration ratio of the voltage change within the time t. The judgment formula is: Among them, p ratio is the duration ratio of the judged voltage change within the time t;

[0046] When 0 < p ratio ≤ 5%, it indicates that the voltage change ratio is within the normal range, indicating a low voltage change frequency. When 5% < p ratio ≤ 10%, it indicates that the voltage change frequency is medium, and the signal is transmitted to the marking sub-module for marking. When p ratio > 10%, it indicates that the voltage change frequency is high, and the signal is transmitted to the early warning sub-module to inform the staff that the electrical appliance voltage is too high, and it is handled by the staff.

[0047] The electrical appliance abnormal early warning test system further includes the following specific steps:

[0048] S1: Monitor the temperature of the electrical appliance while testing the voltage change frequency of the electrical appliance;

[0049] Specifically, the temperature monitoring sub-module monitors the temperature of the electrical appliance during the test voltage in real time, and transmits the signal to the temperature comparison sub-module. The staff sets the normal temperature of the electrical appliance during use in the temperature comparison sub-module, and compares the real-time monitored temperature with the set temperature to judge the temperature of the electrical appliance during monitoring;

[0050] S2: Combine the electrical appliance temperature with the electrical appliance voltage frequency to judge the overall quality of the electrical appliance and ensure the quality of the electrical appliance;

[0051] S2 includes the following specific operation steps:

[0052] S21: When the electrical appliance temperature is normal and the electrical appliance voltage frequency is low, it indicates that the electrical appliance quality is high;

[0053] S22: When the electrical appliance temperature is normal and the electrical appliance voltage frequency is high, it indicates that the electrical appliance frequency is not affected by the temperature;

[0054] S23: When the electrical appliance temperature is high and the electrical appliance voltage frequency is high, at this time, the temperature in the workshop is monitored through the temperature sensor, and it is analyzed whether the electrical appliance temperature is affected by the workshop temperature, thereby affecting the electrical appliance voltage.

[0055] S23 includes the following specific operation steps:

[0056] S231: When the temperature of the electrical appliance is high, the voltage frequency of the electrical appliance is high, and the temperature of the workshop is normal, it means that the temperature of the electrical appliance has no effect on the voltage frequency of the electrical appliance, indicating that the quality of the electrical appliance is poor. At this time, the signal is transmitted to the early warning submodule for processing by the staff;

[0057] S232: When the temperature of the electrical appliance is high, the voltage frequency of the electrical appliance is high, and the temperature of the workshop is high, the signal is transmitted to the adjustment submodule, and the air temperature processing equipment is started by the adjustment submodule to lower the temperature in the workshop. At this time, the temperature of the electrical appliance is monitored again by the temperature monitoring submodule, and the temperature of the electrical appliance is judged again. If the temperature of the electrical appliance drops, it means that the temperature of the electrical appliance is affected by the temperature of the workshop, which proves that the quality of the electrical appliance is medium. If the temperature of the electrical appliance does not drop, it means that the temperature of the electrical appliance is not affected by the temperature of the workshop, which proves that the quality of the electrical appliance is low. The signal is transmitted to the early warning submodule for processing by the staff.

[0058] It should be added that the air temperature processing device can be an air conditioner.

[0059] Through the above steps, the influence of the workshop temperature on the electrical appliance can be determined when testing the voltage of the electrical appliance, thereby improving the test quality.
