实现同时数据采集和显示的压力测量系统
摘要：
本实用新型公开了一种压力测量系统，实现了在试验IMP数据采集系统和现场DCS中同时采集和显示压力测量值。该系统包括试验IMP数据采集系统、试验压力变送器、现场DCS测量显示系统，DCS测量显示系统的正极接入试验压力变送器的正极，试验压力变送器的负极接至试验IMP数据采集系统的负极，试验IMP数据采集系统的24V直流加电接线处短接，试验IMP数据采集系统的正极与DCS测量显示系统的负极相连，试验IMP数据采集系统与DCS测量显示系统串联连接。通过接线方式的合理设计，试验数据采集系统和DCS测量系统的内部结构和接线不用改动，保证了测量系统的精度和稳定性不变，同时大大降低了现场的工作量。
摘要（英）：

The utility model discloses a pressure measurement system. The pressure measurement value is acquired and displayed in a testing interface message processor (IMP) data acquisition system and a field data communication system (DCS). The system comprises a testing IMP data acquisition system, a testing pressure transmitter and a field DCS measurement display system, wherein the positive pole of the DCS measurement display system is connected with the positive pole of the testing pressure transmitter; a negative pole of the testing pressure transmitter is connected to the negative pole of the testing IMP data acquisition system; a 24V direct current electrified wiring part of the testing IMP data acquisition system is in short circuit; the positive pole of the testing IMP data acquisition system is connected with the negative pole of the DCS measurement display system; and the testing IMP data acquisition system is connected in series with the DCS measurement display system. Due to reasonable design of the wiring mode, the inner structure and wiring of the testing data acquisition system and the DCS measurement system are not required to be modified, the precision and stability of the measurement system are kept invariable, and the field workload is greatly reduced.
