Based on the research of dynamic gas distribution principle and automatic control technology,this paper develops an in-situ online calibration device for flammable and explosive gas monitoring system.Through the de-sign of dynamic gas distribution module,power supply module,automatic control module and communication mod-ule,dynamic and accurate gas flow control,automatic preparation of standard gases of different concentrations,soft-ware automatic control,and data communication,processing and management are realized.The results show that the device is reliable and effective,and can meet the requirements of in-situ on-line calibration of flammable and ex-plosive gas monitoring system.
