摘　　要：为进一步提升自动气象站计量检定工作的自动化水平,简化气压传感器示值超差调整工作,通过对PTB220气压传感器工作原理的分析与研究,利用省级气象计量检定业务系统(3MS)的部分硬件,采用串口通信自动应答技术,在原有3MS系统自动化检定的基础上实现了PTB220气压传感器数字量及模拟量示值超差的自动调整。文中详细阐述了数字量及模拟量调整的原理及操作流程,给出了串口通信参数配置及自动调整软件部分代码示例,并通过实际业务验证了系统设计思路的可行性。In order to improve the automation level of automatic weather station testing work and simplify the adjustment of the PTB220 barometer, the working principles of PTB220 are analyzed. By using the parts of the 3MS system hardware, the automatic adjustment function of indication errors is realized based on the automatic response technology of serial communication. In this paper, the principles and operation flow of digital quantity and analog quantity adjustments are expatiated in detail. The configuration of the serial communication parameter and the example of source codes are given for example and the feasibility of the system design is verified by actual operation
