摘　　要：该文针对气象用的PTB220、PTB330气压传感器检定效率低,检定中存在人工误差等现状,研发了多路气压检定系统。系统采用具有8个RS-232/422/485的三合一串口的MOXA-Nport5650-8-DTL型号串口服务器,实现了8个气压传感器的同步检定和数据处理,提高了气压检定的工作效率,排除人工检定带来的误差。The PTB220 and PTB330 air pressure sensors for meteorology are low in efficiency,and there are artificial errors in the verification.A multi-channel air pressure verification system was developed.In the system MOXA-Nport5650-8-DTL serial port server with 8 RS-232/422/485 three-in-one serial ports was adopted to realize synchronous verification and data processing of 8 air pressure sensors,which improves the working efficiency of air pressure verification.Eliminate errors caused by manual checks.
