Abstract: In order to realize the real-time monitoring of the temperature in the effective working area of the high temperature aging system,and avoid the failure and damage of the chip or electronic component caused by abnormal temperature,according to the principle that the output thermoelectric potential of the continuous thermocouple is always corresponding to the highest temperature in the temperature sensing section,a set of real-time temperature measurement system using the continuous thermocouple as the temperature sensing element is built.The system is simple in layout and low in cost.The real-time temperature measurement system is used to verify the test data of the constant state and the temperature gradient state respectively,and the expected effect can be achieved.The system can effectively monitor the aging system working area temperature,achieve centralized monitoring,and according to the chip or electronic components aging temperature,be free to set early warning and alarm temperature points.
