The existing temperature protection system can only set a high-temperature protection value and a low-temperature protection value, if the high-temperature protection value is set to be +75 ℃, and the low-temperature protection value is set to be-10 ℃, the equipment cannot give an alarm as long as the temperature of an equipment working chamber is between-10 ℃ and +75 ℃, so that the phenomenon that the test is out of tolerance, but the equipment does not give an alarm, and a person on duty in the test cannot find the problem in time under some conditions. Assuming that the temperature of the working chamber of the test box reaches +70 ℃ 30min after the test is started, but equipment failure is caused by some reason in the high-temperature heat preservation section, when the heat preservation is carried out for 1h, the temperature of the working chamber of the test box becomes +45 ℃, the test seriously exceeds the standard requirement, but the equipment still cannot send alarm information, finally the test fails, and the test needs to be carried out again.
