Decentralized control system background database POU page dynamic generation method, system, device and medium

The invention belongs to the field of decentralized control systems, and discloses a method, a system, equipment and a medium for dynamically generating a POU page of a background database of a decentralized control system. When a background program of an upper computer updates a point directory in real time, a process control station compares a received cyclic redundancy check code of the POU page with a check code in a POU check code array; the POU page data record and the measuring point information record are updated according to the distribution condition of the measuring points and all the measuring point information of the POU page of the process control station, so that the POU page data record can be dynamically added and deleted for each process control station in the real-time database, m POU page data records do not need to be fixedly generated, and the limited POU data record capacity is utilized to the maximum extent. 本发明属于分散控制系统领域，公开了分散控制系统后台数据库POU页动态生成方法、系统、设备及介质，本发明上位机后台程序实时更新点目录的过程时，将过程控制站将接
