[0001] The present invention belongs to the technical field of automatic switch stations, and specifically relates to a smart station automatic switch station system and method based on message publishing and subscription. Background Art

[0002] In addition to providing passengers with more intelligent and humanized services, smart stations can also help station operators improve their work efficiency. Automatic switch stations are a typical new technology to improve station operation efficiency. Automatic switch stations can quickly realize safety confirmation of station switches, system self-checking, equipment action and status feedback, reduce labor costs, improve the timeliness of station equipment management, improve the intelligent operation and operation management functions of stations, and provide intelligent and high-quality services for station management.

[0003] In the traditional automatic switch station system, the automatic switch station server and the automatic switch station client communicate by direct connection. The automatic switch station server and the automatic switch station client are tightly coupled, and the two are too dependent on each other, which is not conducive to modular processing and is not convenient for the efficient development of multiple working surfaces of the automatic switch station system.

[0004] In addition, when considering adding a backup automatic switch station service, the complexity of maintaining the communication between the automatic switch station client, the automatic switch station server, and the backup automatic switch station server will be very high, which is not conducive to the scalability and high availability of the system. Summary of the invention

[0005] In view of the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide a smart station automatic switch station system and method based on message publishing and subscription, which decouples data communication and data synchronization from the automatic switch station client and the automatic switch station server through the publishing and subscription of the real-time database, facilitates the modular processing of the automatic switch station system, and improves the development and maintenance efficiency of the automatic switch station system to a certain extent.

[0047] The publishing of the execution status of the automatic switch station system refers to the main automatic switch station server or the automatic switch station client sending the execution status of the automatic switch station system to the real-time database, and the real-time database updates the stored execution status of the automatic switch station system.

[0048] Among them, the receiving of subscription to the execution status of the automatic switch station system refers to the real-time database saving the socket connection list of all subscribers and the real-time database. When the execution status of the automatic switch station system stored in the real-time database is updated, the real-time database will send the updated execution status of the automatic switch station to all subscribers.

[0049] Reference Figure 2 As shown, a method for realizing a smart station automatic switch station based on message publishing and subscription of the present invention is based on the above system, and the steps are as follows:

[0050] 1) The automatic switch station client publishes the execution status of the automatic switch station system to the real-time database; specifically, the automatic switch station client stores the execution status of the automatic switch station system, that is, the control instruction is set to start, and the instruction execution result of the automatic switch station terminal device is set to the initial value; the automatic switch client publishes the stored execution status of the automatic switch station system to the real-time database.

[0051] 2) The real-time database sends the execution status of the automatic switch station system to the main automatic switch station server and the backup automatic switch station server; specifically, the real-time database stores the execution status of the automatic switch station system published by the automatic switch station client and sends it to the subscribers, namely the main and backup automatic switch station servers.

[0052] 3) The main automatic switch station server sends the execution instructions of the automatic switch station equipment terminal to the real-time database; specifically, the main automatic switch station server parses the execution status of the automatic switch station system, and after parsing the control instruction to start, it sends the specific execution instructions of the automatic switch station equipment terminal to the real-time database, such as open and close.

[0053] 4) The real-time database forwards the execution instruction of the automatic switch station equipment terminal to the automatic switch station equipment terminal;

[0060] 11) The automatic switch station client determines whether all automatic switch station equipment terminals have completed execution. If so, the process ends. If not, it returns to step 1).

[0061] After the main and auxiliary automatic switch station servers are started, they will register with the real-time database. The automatic switch station server that registers first is the main automatic switch station server, and the automatic switch station server that registers later is the backup automatic switch station server. The main automatic switch station server and the backup automatic switch station server periodically send status information to the real-time database. When the real-time database obtains that the main automatic switch station server has a fault, the real-time database sends a message to the backup automatic switch station server to notify it to upgrade to the main automatic switch station server. When the original faulty main automatic switch station server successfully re-registers with the real-time database and works, it will be notified as the backup automatic switch station server.
