针对水电厂生产现场多功能百超表无法开展检定的难题,成功研发了该表的自动校验系统。该系统充分考虑了现场遥测输入回路接口的特殊性,采用现代检测、高速采样、复杂的可编程逻辑阵列等高精密电子芯片,开发了功能强大的通信协议配置库,完成了校验仪器与被测装置的MB+(Modbus plus)协议通信,能够满足国内使用各种通信协议输出的多功能仪表的检定要求,真正实现了对多功能百超表的全自动校验,系统通过了权威部门的认证,填补了国内该校验领域的空白。
In view of the difficulty that the multi-functional super-scale can not be verified in the production site of the hydropower plant, an automatic calibration system for the meter has been successfully developed. The system fully considers the particularity of the field telemetry input circuit interface, and adopts modern high-precision electronic chips such as modern detection, high-speed sampling and complex programmable logic array to develop a powerful communication protocol configuration library and complete the verification of the instrument Test device MB + (Modbus plus) protocol communications, to meet the domestic use of a variety of communication protocols to output multi-function instrument verification requirements, truly multi-function automatic calibration table, the system passed the certification authority , To fill the gaps in the field of calibration of the country.
