Automatic Batch Calibration Test System of Infrared Gas Sensor Based on LabVIEW
Aiming at the problems of low efficiency,heavy workload and error-prone in the calibration process of infrared gas sensors,an automatic batch calibration test system for infrared gas sensors based on LabVIEW was designed.The system consisted of infrared gas sensor,flowmeter,incubator,acquisition board and upper computer.The software program was written by LabVIEW,and its functions include parameter setting,connectivity test between the acquisition board and the infrared gas sensor,controlling the temperature box and flowmeter to realize regular heat preservation and regular introduction of proportional gas,acquiring infrared gas sensor data,automatic calibration,automatic data processing and so on.The software adopted multi-thread programming to ensure that all functions can be carried out at the same time,and has the advantages of beautiful interface,fast running speed,strong stabili-ty and high reliability.The calibration test results show that the system is compact in structure,stable in operation and simple in operation.The system can be efficiently and widely used in the automatic calibration of a large number of infrared sensors in real life.
