if the effective measuring point information associated with the key word does not exist in the effective measuring point buffer area, the following judgment is carried out: if the current measurement point information meets the second constraint condition, setting the measurement point identifier of the measurement point information to be 0, adding the measurement point information into a secondary verification list, otherwise, taking the measurement point name of the current measurement point information as a keyword, generating effective measurement point information according to all attribute values of the current measurement point information, and adding the effective measurement point information into an effective measurement point buffer area;
s22: traversing the secondary check list generated in the S21, adding a condition field with the effectiveness of the measuring point being 1 to a database path of the current measuring point information in the secondary check list, inquiring a measuring point database, and updating all attribute values of the current measuring point information and updating an effective measuring point cache area if the measuring point information with the effectiveness of the measuring point being 1 is successfully obtained again; if the acquisition of the measuring point information with the measuring point validity of 1 fails, the database path of the current measuring point information is emptied, and the measuring point validity is set to 0;
and an empty path measuring point updating module: the method comprises the steps of traversing an empty path measuring point list formed in a grouping module, recombining a database path of current measuring point information one by one according to the measuring point names of the current measuring point information in the empty path measuring point list, inquiring a measuring point database according to the database path, and updating the current measuring point information according to an inquiring result;
the subscription measurement point list generation module: the method comprises the steps of performing secondary grouping on all the measurement point information of a DCS picture after verification and updating by a measurement point verification module and an empty path measurement point updating module according to whether a database path of the measurement point information is empty or not, and adding the measurement point information of which all the database paths are not empty into a subscription measurement point list;
a subscription message receiving and transmitting module: the system comprises a subscription measurement point list generation module, a lower computer, a real-time value message and a real-time value message, wherein the subscription measurement point list generation module is used for generating a subscription reading message according to the subscription measurement point list obtained by the subscription measurement point list generation module, and transmitting the subscription reading message to the lower computer;
and a database updating module: and the system is used for periodically updating the measuring point database according to the real-time value message fed back by the lower computer in the subscription message receiving and transmitting module.
6. Computer device comprising a memory, a processor and a computer program stored in the memory and executable on the processor, characterized in that the processor implements the steps of the DCS screen station verification and subscription method of any of claims 1 to 4 when the computer program is executed.
7. A computer readable storage medium storing a computer program, wherein the computer program when executed by a processor implements the steps of the DCS screen site verification and subscription method of any one of claims 1 to 4.
