Method for automatically calibrating CO2 detection precision of livestock and poultry house

Abstract

The invention discloses a method for automatically calibrating CO2 detection precision of a livestock and poultry house. Belonging to the technical field of sensors, the device comprises a first detector and a second detector, the first detector detects parameters of corresponding target gas in the environment in real time and sends the parameters to the controller; the second detector is used asa calibration sensor; starting and collecting parameters of corresponding target gas in the current environment according to a preset mode; the acquired parameters are sent to the controller; the controller compares the current measurement information sent by the first detector with the measurement information sent by the second detector; whether the measured value of the first detector is calibrated or not is judged; and when the calibration time interval is smaller than the minimum time interval value allowed by the preset calibration, the system turns off the first detector, turns on the second detector, takes the second detector as a sensor which works normally, and meanwhile, controls the alarm to give an alarm.

Description

technical field [0001] The utility model belongs to the technical field of sensors, in particular to a CO 2 A method for automatic calibration of detection accuracy. Background technique [0002] When CO 2 When the sensor has base point drift, aging and other phenomena after long-term use, the collected CO 2 The concentration is inconsistent with the actual value, and the accuracy is not accurate, which leads to errors in the control of air quality. Contents of the invention [0003] The object of the present invention is to provide a CO 2 The method of automatic calibration of detection accuracy, by setting the first detector and the second detector, the first detector is used as a common detector, and the parameters of the corresponding target gas in the environment are detected in real time, and then sent to the controller, and the second detector is used as Calibrate the detector, open and collect the parameters of the corresponding target gas in the current enviro...
