Abstract

The invention provides a sensor calibration system, a control method and a control device thereof. The sensor calibration system comprises a measurement sensor, a calibration sensor and a controller, wherein the measurement sensor is arranged in an open space. The calibration sensor is arranged in a housing structure, wherein the housing structure comprises a fixed part, a movable part and a transmission part which is connected with the movable part. The transmission part can drive the movable part to reciprocate according to a control instruction. Furthermore when the movable part seamlessly abuts against the fixed part, the movable part and the fixed part form a closed space; when the movable part does not abut against the fixed part seamlessly, the movable part and the fixed part form an open space. The controller is connected with the measurement sensor and the calibration sensor and transmits control instruction to the transmission part. The sensor calibration system can output accurate sensor data after long-term use of the sensors.

Description

technical field [0001] The present application relates to the field of automation technology, in particular to a sensor calibration system and its control method and device. Background technique [0002] With the increasingly serious environmental pollution, one or more of PM2.5 sensors, temperature sensors, and humidity sensors are generally installed in home appliances such as household air purifiers and air conditioners, so that these sensors can be used to detect the corresponding PM2. 5 One or more of concentration, temperature and humidity. [0003] However, as the use time of the home appliance increases, substances such as dust are generally attached to the internal sensors, and these substances will affect the data accurately measured by the sensors. Taking the PM2.5 sensor as an example, when dust is attached to the PM2.5 sensor, it will affect the PM2.5 concentration measured by the PM2.5 sensor, which will cause the PM2.5 sensor to output an inaccurate PM2.5 con...
