The invention provides an automatic calibration system and method for a sensor. Sensors are used for collecting sensor data and uploading the sensor data to a gateway; the gateway transmits the sensordata uploaded by the sensors to a cloud platform; a standard metering module is used for acquiring real value data of the sensor data corresponding to each sensor and transmitting the real value datato the cloud platform; the cloud platform is used for transmitting the acquired sensor data and the real value data to a big data platform; the big data platform is used for storing and transmittingthe acquired sensor data, the real value data and other condition data to the calibration module, wherein the other condition data are automatically counted and can affect the accuracy of the sensors;the calibration module is used for analyzing the obtained data to obtain a calibration model corresponding to target calibrated sensors or obtain a calibration model by means of machine learning; andthe calibration model is used for calibrating data during sensor calibration and then outputting a calibrated result.
Description
Technical field [0001] The invention relates to the field of automatic calibration, in particular to an automatic calibration method and system for sensors. Background technique [0002] With the rapid development of the Internet of Things field, the application of sensors has become more and more extensive, in all walks of life, a large number of sensors are used in various environments, and different environments will have a certain degree of impact on the electronic devices of the sensors. Temperature, humidity, electromagnetic field, the use time of the device, etc. will affect the sensor, resulting in inaccurate sensor data, and even more and more deviation from the actual value. Therefore, sensor calibration is becoming more and more important. However, even the same sensor device itself lacks consistency. For sensors with poor consistency, it is necessary to verify each batch or even each sensor product. At present, most sensor calibration methods require on-site manual ...
