System and method for measuring shutoff temperature of electronic product

Abstract

The invention provides a system for measuring shutoff temperature of an electronic product. The system comprises a controller, a temperature controlling box, a measured part which is arranged in the temperature controlling box, a power supply which is used for providing the electricity to the measured part, a switch which is used for controlling the temperature of the temperature controlling box and the power supply and a relay, wherein the measured part comprises a normally open contact switch which is used for starting the measured part, the normally open contact of the relay and the normally open contact switch are connected in parallel, a coil winding of the relay and the power supply loop are connected in serial, and the controller is used for controlling the power supply to supplying the electricity to the relay. The measured part is started through the connection of the relay, when the measured part cannot be shut off due to the effect of the temperature difference, the measured part can be restarted, the operation condition of the measured part can be monitored, and whether measuring results are accurate can be determined.

Description

technical field [0001] The invention belongs to the field of electronic product testing, in particular to a system and method for testing the shutdown temperature of electronic products. Background technique [0002] Electronic products will generate a lot of heat after a long period of continuous use, resulting in an increase in operating temperature. When the operating temperature exceeds the range that the electronic product can withstand, not only the components of the electronic product will be damaged, which will seriously affect its service life; It can also harm the user. Therefore, it is necessary to take certain measures to ensure that electronic products work within the set temperature range, such as forced shutdown or cooling. And testing the temperature range of safe operation of electronic products is the key for electronic product manufacturers to ensure the safe operation of electronic products. [0003] The usual practice is to place the electronic product...
