Quality control method suitable for remote quality control system of gas multi-parameter monitor

The invention provides a quality control method suitable for a remote quality control system of gas multi-parameter monitor. The remote quality control system comprises a multi-way valve, a zero gas generator, a standard gas cabinet, a mixed gas chamber, a control module and an industrial personal computer; according to the quality control method, the control module adopts a PID algorithm, parameters in ax and ey are finely adjusted in the quality control process respectively, and when the parameters of a first mass flow controller are adjusted, ax'+ey=z is obtained, and when the parameters of a second mass flow controller are adjusted, ax+ey'=z is obtained until the output standard gas detected by atmospheric monitoring national standard equipment is z, the configuration parameter x' of the first mass flow controller and the configuration parameter y' of the second mass flow controller are obtained. 本发明提供一种适用于气体多参数监测仪的远程质控系统的质控方法，所述远程质控系统包括多通阀、零气发生器、标气柜、混合气室、控制模块和工控机；所述质控方法：所述控制模块采用PID算法，质控过程中，分别微调整ax、ey中的参数
