Temperature sensor detection method based on measurement precision

Abstract

The invention discloses a temperature sensor detection method based on measurement precision. The temperature sensor detection method comprises the following steps of putting a standard temperature sensor and a temperature sensor under detection in the same temperature environment; acquiring a first instant temperature measured by the standard temperature sensor and a second instant temperature measured by the temperature sensor under detection; and comparing the first instant temperature and the second instant temperature to determine whether the temperature sensor under detection is qualified or not. Using the temperature sensor detection method, a user can perform fine detection on the performance of temperature sensors and find out unqualified temperature sensors through the detection, so that when qualified temperature sensors are applied to a steel breakout forecast system, false alarms and failed reports are prevented as much as possible, and accidents of steel breakout are effectively prevented.

Description

Technical field [0001] The invention relates to a temperature sensor detection method based on measurement accuracy. Background technique [0002] In the process of steel casting, accidents such as leakage often occur. The leakage endangers personal safety, damages equipment, causes production to be interrupted, and affects the output, production efficiency, and product quality of casting machinery. The loss of a leakage can be as few as dozens. Ten thousand, many millions. Therefore, many casting machines will install a breakout prediction system to reduce the possibility of breakout accidents. The principle of the breakout prediction system is to track and detect the temperature in the casting machine through the temperature sensor, and judge whether there will be a breakout based on the detected instantaneous temperature, so as to prevent the occurrence of a breakout. [0003] However, due to the complex application scenarios in the casting machinery and the extremely high tem...

Problems solved by technology

[0003] However, due to the complex application scenarios and extremely high temperature in the foundry machinery, the temperature sensor for temperature detection in it is easily damaged during use, and there is no method in the prior art that can accurately detect the accuracy and response rate of the temperature sensor. method, so that the temperature sensor that does not meet the requirements cannot be identified, which greatly increases the probability of false alarms and false alarms in the steel breakout prediction system, which seriously affects the normal operation of casting machinery, and there are great safety hazards, which need to be improved urgently
