Remote calibration system and its sensor remote calibration method

摘要

PROBLEM TO BE SOLVED: To provide a remote calibration system and a remote calibration method for a sensor thereof, and to remotely calibrate a sensor in a timely manner. A remote calibration system having a sensor and a monitoring host, the sensor senses the environment to generate an environmental state signal, generates sensing parameters based on the environmental state signal and reference level, and uploads them to the monitoring host. To do. When the monitoring host obtains the standard parameters corresponding to the calibration timing and determines that the calibration timing is satisfied, it calculates the deviation data based on the standard parameters and the sensing parameters, generates the update data and sends it to the sensor, and thus the sensor. Calibrates the reference level based on the updated data. The present invention can extend the life of the sensor, improve the accuracy of the sensing parameters, and save maintenance time and labor cost through automatic remote calibration of the sensor.
