摘要：

针对安全阀离线校验操作管理不便、工作效率低下、数据不准确、安全阀不便运输等问题，开发了OA系统、安全阀校验操作软件和以STM32单片机为控制核心的小型安全阀离线校验台构成的安全阀离线校验系统。以WIFI无线通信技术作为传输手段，结合传感器技术，将下位机采集到的安全阀压力数据传输给上位机，并在安全阀校验操作软件上用曲线图实时显示，实现安全阀校验系统网络化、信息化、校验结果准确程度高、校验效率高和降低成本。该研究将为特种承压设备校验提供可靠的数据支持，对安全阀离线校验操作规范提出新的参考。

Abstract: In order to solve the problems of inconvenient operation and management, low work efficiency, inaccurate data and the safety valve transported inconveniently, A system of safety valve off-line calibration was developed with the OA system, the operated software of safety valve calibration and the equipment of the safety valve off-line calibration with microcontroller called STM32 as the control core. Combining with sensor technology, Data of the safety valve in pressure acquired by the slave computer in the system was transmitted to the host computer by WIFI wireless network technology, and the curve chart was displayed on the software in real time. It realized the network of the safety valve calibration system,informatization, the high accuracy of the verified results, the improvement of the calibrated efficiency and reducing the cost.The research will provide accurate data for the verification of the special pressure equipment, and find a new method for the off-line safety valve calibration comply to standard.
