井下存储式电子压力计数据丢失原因分析及处理方案设计

Analysis of Data Loss for Down Hole Storage Electronic Pressure Gauge and Its Treatment Design

对井下存储式电子压力计在使用过程中存在的问题进行分析,提出应用外部看门狗电路、数据冗余技术相结合的设计方案,用以解决井下存储式压力计数据存储不全问题,为其它测控系统,在选择热启动及数据恢复的方案中提供参考作用。

By analyzing applied status of the down hole storage electronic pressure gauge in well testing and the existing problems in using process,the application of external watchdog circuit,data redundancy technology of combining the design is put forward in order to resolve the problem of no full storage of down-hole pressure gauge data,which provides a reference for other control system in the plan of choosing hot start and data recovery.
