The related systems include an intelligent low-voltage system (ILVS), an electrical and mechanical control system (EMCS), an integrated supervisory control system (ISCS), etc. The aforementioned low-voltage professional systems adopt a hierarchical architecture, from top to bottom in turn ISCS, EMCS and ILVS, wherein ILVS implements field-level electrical and mechanical equipment monitoring, EMCS implements station-level electrical and mechanical equipment monitoring, and ISCS implements integrated station comprehensive monitoring of multiple professionals. Among them, ILVS is a field-level electrical and mechanical equipment monitoring system, EMCS is a station-level electrical and mechanical equipment monitoring system, and ISCS is a multi-professional integrated station equipment monitoring system.

A method for implementing a digital base in a subway station, using the subway station digital base system according to claims 1-4, characterized in that: S1) The base controller establishes an instance data cache and an instance data replica, wherein the cache is used to store historical physical model instance data, and the instance data replica is used to store real-time physical model instance data; S2) The base controller obtains the physical model instance data of the station field equipment through the first protocol and saves the historical physical model instance data to the instance data cache, and saves the real-time physical model instance data to the instance data copy; S3) The base controller accepts a call from the base server through a second protocol, wherein if the base server calls real-time object model instance data, the base controller pulls data from the instance data copy; if the base server calls historical object model instance data, the base controller pulls data from the instance data cache; S4) the base server respectively creates an ILVS virtual host, an EMCS virtual host, and an ISCS virtual host, and calls the object model instance data through the second protocol, the ILVS virtual host processes the object model instance data and updates it into ILVS professional WEB page monitoring data, the EMCS virtual host processes the object model instance data and updates it into EMCS professional WEB page monitoring data, and the ISCS virtual host processes the object model instance data and updates it into ISCS professional WEB page monitoring data; S5) The ILVS application terminal uses HTTP to call the ILVS professional WEB page monitoring data for display and monitoring; the EMCS application terminal uses HTTP to call the WEB page of the EMCS virtual host for display and monitoring; The ISCS application terminal uses HTTP to call the ISCS professional WEB page monitoring data for display and monitoring.

6. The method for implementing a digital base in a subway station according to claim 5, characterized in that: The object model instance data is structured data in JSON format.

7. The method for implementing a digital base in a subway station according to claim 5, characterized in that: The first protocol is the MQTT protocol, and the second protocol is an API interface protocol. The API interface protocol is used to pull ILVS, EMCS and ISCS data.

8. The method for implementing a digital base in a subway station according to claim 5, characterized in that: The display and monitoring are achieved through WEB pages.

9. A digital base device for a subway station, characterized in that: including memory and processor; The memory is used to store computer programs; The processor is configured to implement the method for implementing a digital base for a subway station as claimed in any one of claims 5 to 8 when executing the computer program.

10. A computer-readable storage medium, characterized in that The storage medium stores a computer program, and when the computer program is executed by the processor, the method for implementing the digital base of a subway station as described in any one of claims 5 to 8 is implemented.
