Automatic isolation detection system for sensor

Abstract

The invention discloses an automatic isolation detection system for a sensor. The system comprises a data acquisition and communication module, a test module, a mathematical model establishing module,an error sourcing module and an error analysis and assessment module. The operation state of the sensor is conveniently monitored in real time through dynamic monitoring, searching of line errors bya tester is facilitated, the signal condition of the sensor is mastered timely, and the testing efficiency is improved; detection by the system finds that errors of the sensor are mainly measurement errors and errors of a standard device; in order to improve the reliability and the stability of the sensor, regular checking and regular testing of the sensor are facilitated through the error analysis and assessment module, so that the reliability and the stability of the sensor are guaranteed; through a detection procedure, high comprehensive detection accuracy, high efficiency and good consistency of the system are realized, and the system has better real-time performance, reliability and maintainability; through the system, the error range of the sensor can be effectively reduced, and a fault sensor can be conveniently and timely found.

Description

technical field

[0001] The invention relates to the technical field of sensor automatic isolation detection systems, in particular to a sensor automatic isolation detection system. Background technique

[0002] Sensors are one of the important test devices in instruments and various products, and are widely used in production and life because of their wide variety, stable performance, and accurate measurement. The sensor automatic test system is to detect temperature sensors and ensure their An important device that meets the test requirements, the error of the system will directly relate to the accuracy of the process parameters measured by the sensor, and ultimately affect the product quality.

[0003] However, the sensor automatic isolation detection system currently on the market is not only complex in structure, but also has a single function, which is not convenient for real-time monitoring of the operating status of the sensor, and it is inconvenient for testers to fi...

Examples

Embodiment

[0023] Example: such as figure 1 As shown, the present invention provides a technical solution for an automatic sensor isolation detection system, a sensor automatic isolation detection system, including a data acquisition communication module, a test module, a mathematical model establishment module, an error source module, an error analysis and evaluation module, and a data acquisition communication module. The module is equipped with data acquisition, dynamic monitoring and stop monitoring.

[0024] According to the above technical scheme, there are test methods and test procedures in the test module. The test method refers to selecting a sensor with stable performance. The resistance and the measured resistance are placed in the constant temperature oil tank at the same time. After the temperature is stable, the system software reads out the resistance values ​​of the two by comparing the standard resistance and the measured resistance point by point, and then calculates t...
