ATT7022B的校表过程十分繁琐,通过计算机软件实现自动校表可以大大提高校表效率和数据的准确度,同时降低校表的劳动强度.本文根据实际校表需要,设计了ATT7022B自动化校表系统,该设计包括串口应用层协议、上位机软件和下位机软件.文中详细介绍了自定义的校表协议,重点讨论了上位机软件设计,给出了上位机、下位机的通信软件流程图,利用Visual C++ 6.0实现了上位机与表模块的通信,完成了以ATT7022B为核心的表模块校验.
摘要(英文)：
The process of ATT7022B calibration is very complicated.Auto-calibration achieved by software can improve the efficiency and accuracy as well as reducing the labor intensity greatly. According to the practical need of calibration, this paper designs AT7022B auto-calibration system, including UART communication protocol, PC software and MC drivers. Also, the paper introduces self-defined calibration protocol, mainly discusses PC software design, presents the communication software flow chart between PC and MC, finally using ...
