A sensor environment setting device and a sensor parameter calibration system

Abstract

The invention discloses a sensor environment setting device and a sensor parameter calibration system. The sensor environment setting equipment includes a temperature control area, a stage, and a pressure regulation and connection device; the stage carries the sensor and is driven by a transmission device to move in the temperature control region; the pressure regulation and connection device is located in the temperature control region, When the stage moves to the pressure regulating and connecting device, the pressure regulating and connecting device puts the sensor carried by the stage under the set air pressure and electrically connects the sensor to the sensor parameter monitoring and setting device located outside the environment setting equipment . The sensor parameter calibration system uses one or more sensor environment setting devices. According to the embodiment of the present invention, an independent sensor environment setting device can be provided separately for each temperature, and then a sensor parameter calibration system with multiple temperature ranges can be formed by flexible combination of multiple sensor environment setting devices, which can ensure the calibration effect of the sensor , which improves the calibration efficiency of the sensor.

Description

Technical field [0001] The present invention relates to a sensor calibration testing, and more particularly relates to a sensor device and the environment is provided a sensor calibration system parameters. Background technique [0002] The sensor is widely used for industrial and agricultural production and daily life has played a very important role. The accuracy of the sensor data of a direct impact on all aspects of industrial agricultural production efficiency, safety, etc., also affect the ease of everyday life. [0003] At present, there are two existing pressure sensor calibration methods: [0004] (1) Manual calibration [0005] A pressure sensor placed in a pressure tank, the pressure tank is then placed in a high temperature tank, the pressure sensor signal through the wire lead. Controlled by an external pressure tank pressure controller, a pressure tank using the tank heating temperature or cooling to achieve temperature and pressure compensation. [0006] Embodiment...

AI Technical Summary

Problems solved by technology

[0006] The problem with method (1) is that: the whole process is entirely manual, and only a few dozen pieces can be calibrated and tested at one time; the process of welding signal lines, locking and sealing the pressure tank, and heating and cooling takes a long time, resulting in the failure of the pressure sensor calibration. low efficiency

[0010] However, due to the way (2) but because the cooling process is removed, the calibration effect is reduced
