Embodiment 1
[0052] An embodiment of the present invention provides a synchronous control method for a control and protection system, which is used in a control and protection system, such as figure 1 As shown, the control system generally includes: a first synchronous signal unit 1 and a second synchronous signal unit 2, the first synchronous signal unit 1 and the second synchronous signal unit 2 are backup equipment for each other, and two synchronous signal units are set here The signal unit is used to ensure the continuous operation of the control and protection system when one of the synchronization signal units fails, and another synchronization signal unit can be used instead. exist figure 1 Among them, the control and protection system also includes a first valve section control unit 11 and a second valve section control unit 12 . exist figure 2 Among them, other control units are also set in the control and protection system, and the other control units are cascaded in sequence...
Embodiment 2
[0073] An embodiment of the present invention provides a synchronous control device for a control and protection system, including: a first synchronous signal unit and a second synchronous signal unit, the first synchronous signal unit and the second synchronous signal unit are backup devices for each other, such as Figure 5 As shown, the following modules are included:
[0074] The selection module 51 is configured to select a synchronization signal unit between the first synchronization signal unit and the second synchronization signal unit as the master control unit, and use the other synchronization signal unit as the slave control unit.
[0075] The first detection module 52 is used to detect whether the main control unit fails.
[0076] The second detection module 53 is used to detect whether the slave control unit is normal if the master control unit breaks down;
[0077] The first control module 54 is used to control the master control unit to send a master-slave cha...
Embodiment 3
[0091] An embodiment of the present invention provides a computer-readable storage medium, on which computer instructions are stored. When the instructions are executed by a processor, the steps of the synchronization control method for the control and security system in Embodiment 1 are implemented. The storage medium also stores failure information of the first synchronization signal unit or the second synchronization signal unit, request change instruction information, synchronization signal information, and the like.
[0092] Wherein, the storage medium may be a magnetic disk, an optical disk, a read-only memory (Read-Only Memory, ROM), a random access memory (Random Access Memory, RAM), a flash memory (Flash Memory), a hard disk (Hard DiskDrive, Abbreviation: HDD) or solid state disk (Solid-State Drive, SSD), etc.; the storage medium may also include a combination of the above types of storage.
[0093] Those skilled in the art can understand that all or part of the proce...
