Abstract

The invention provides a sensitivity calibration system and method for a fuel gas odorant concentration measurement sensor. The system comprises a control device, a fuel gas odorant concentration measurement sensor, a calibration electromagnetic valve and a fuel gas odorant storage device, wherein the fuel gas odorant concentration measurement sensor is used for acquiring the current concentrationvalue of a fuel gas odorant, the calibration electromagnetic valve is used for receiving the control of the control device and opening or closing the valve, the fuel gas odorant storage device is used for storing a fuel gas odorant with a calibrated concentration, and the control device is used for sending a control instruction to the calibration electromagnetic valve every a first preset duration, receiving the current concentration value, acquired by the fuel gas odorant concentration measurement sensor, of the fuel gas odorant, and correcting the sensitivity of the fuel gas odorant concentration measurement sensor according to the current concentration value and the calibration concentration of the fuel gas odorant with the calibration concentration. According to the invention, inaccurate measurement caused by the sensitivity problem of the fuel gas odorant concentration measurement sensor is avoided.

Description

technical field [0001] The present application relates to the field of gas odorant concentration measurement, in particular to a sensitivity calibration system and method of a gas odorant concentration measurement sensor. Background technique [0002] At present, it is necessary to use a gas odorant concentration measurement sensor to periodically measure the concentration of gas odorant in the gas source station to monitor the dynamic change of gas odorant concentration, so as to ensure that the gas source station can provide gas services normally. [0003] However, as the number of measurements increases, the sensitivity of the gas odorant concentration measurement sensor will decrease, making it impossible to measure the true concentration of gas odorant, which in turn will cause the gas source station to fail to provide gas services normally. Contents of the invention [0004] The embodiments of the present application provide a sensitivity calibration system and metho...
