Problems solved by technology

In the existing technology, sensor calibration is divided into hardware debugging and software calibration. In the process of software calibration, the firmware needs to be refreshed frequently as a whole, which brings a lot of inconvenience. Recorder, frequent startup; and the overall firmware needs to be refreshed during the calibration process, which often brings other errors and reduces the user experience of using the sensor
[0003] For the above-mentioned sensor calibration process, it is necessary to refresh the firmware as a whole, which brings great inconvenience and further reduces the user experience of using the sensor. At present, no effective solution has been proposed.

Abstract

The invention provides a sensor assembly calibration method, device and system, and the method comprises the steps: enabling a cloud server to obtain an environment monitoring parameter of a target sensor assembly, storing the environment monitoring parameter in a database, and displaying the environment monitoring parameter to a user; calculating the calibration value of a corresponding sensor in the sensor assembly according to a calibration command when the cloud server receives the calibration command sent by the user according to the environment monitoring parameter, carrying out the encryption of the calibration values, forming a calibration command encryption flow, and transmitting the calibration command encryption flow to the sensor assembly for calibration. According to the invention, the cloud server is used for calculating the calibration value of the sensor assembly, encrypts the actual value of environment monitoring, transmits the actual value to the sensor assembly for cloud calibration, enables the whole calibration process to be quick and convenient, does not need a worker to carry out operation on a site, effectively avoids a data drift phenomenon caused by long-time operation, and improves the user experience.
