Background technique

The railway dispatching command system is abbreviated as TDCS, which mainly completes the records, analysis, vehicle number check, automatic report, positive and late point statistics, automatic drawing of operation charts, scheduling commands and planned release, and automatic generation of driving logs. The dispatching centralized system is referred to as CTC. In addition to completing all the functions of the TDCS, the CTC can also complete the automatic selection of the train approach according to the plan. The manual operation function of the station signal equipment is divided into two modes: decentralized self-discipline control and very station control.

An important function of CTC is to track and store critical states. The stability and security of storage in critical states are of great significance to railway dispatching and command.

1 is a flow diagram of a method of processing a critical logic state in accordance with an embodiment of the present disclosure. Embodiments of the present disclosure store the most recent critical logic state in a database as the critical logic state changes. When the critical logic state in the CTC is abnormal and needs to be recovered, the stored critical logic state is read from the database. If the critical logic state cannot be read from the database, the critical logic state is set to a safe state. The embodiment of the present disclosure caches the key logic state in the self-regulator memory and saves it in the database. When processing the manual operation and the access card control judgment, directly reading the key logic state stored in the memory of the self-regulator, and improving The efficiency of execution. When the critical logic state stored in the memory of the autonomous machine is not available and needs to be reinitialized, the technical solution of the present disclosure acquires the persistently saved data from the database and reinitializes the critical logic state. The present disclosure uses a database to synchronize critical logic states, and storing critical logic states through the database is more reliable and efficient. As shown in FIG. 1, a method 100 of processing a critical logic state begins at step 101:

Further, in the initialization, the present disclosure first determines which critical states each device should have (eg, whether there is a zone blockade), and then queries the database for the current state of these critical states (with or without blocking). Further, the present disclosure includes a process of initializing a critical logic state, first determining which critical states each device should have, such as whether the device has a zone blockade, or whether there is a bad branch state, etc., and then going to the database to query the key logic.

Further, the critical logic state includes: a shunt failure state of the segment, and the shunt failure state of the segment includes: no shunt failure, no shunt failure, unacknowledged idle, and shunt failure confirmation idle. Further, the critical logic state includes: a blocked state of the segment, and the blocked state of the segment includes: blocked and unblocked.

Further, the method further includes setting, by the state of the user input or the signal device, each of the plurality of key logic states, and sending the set key logic state to the self-regulator, and performing verification processing by the autonomous machine. The key logic state is saved to the database synchronously after the verification process. In the present disclosure, the system monitors the critical logic state, manually sets the logic state by the user, or performs linkage change of the key logic state record according to the state of the signal device. In the disclosure, the CTC system implements this function: setting and display, the user operates the critical logic state in the CTC terminal, transmits to the self-regulator, and is processed by the self-regulator. After the operation is successful, the state is returned to the terminal for display, and synchronization is performed. Save to the database.

Further, including deleting any of the plurality of critical logic states by user input.

Further, in step 102: determining whether a critical logic state in the centralized system changes, when the first critical logic state changes, acquiring the latest state data of the first critical logic state and based on the latest state data to the first critical logic The status is updated, the updated first critical logic state is stored in the database, and the updated first critical logic state is sent to the self-regulator.

Further, in step 103: after an abnormality occurs in the second critical logic state in the self-regulator, the database is searched according to the running device associated with the second critical logic state to determine a second key stored in the database that does not have an abnormality. The logic state sends a second critical logic state to the autonomous machine to synchronize the critical logic states.

Further, in the case of abnormal recovery, the present disclosure first determines which critical states each device should have (eg, whether there is a zone blockade), and then queries the database for the current state of these critical states (with or without blocking).

When the second critical logic state in the autonomous machine needs to be restarted, the last saved second critical logic state is loaded from the database, and the second critical logic state in which the exception occurs in the autonomous machine is replaced.

Further, when the critical logic state stored in the read database fails, the critical logic state is set to a state that is directed to security. In the present disclosure, when the critical logic state changes, the latest critical logic state is stored in the database in real time. When the system has an exception that needs to be recovered, the critical logic state data is read from the database. If critical logic state data cannot be read from the database, the critical logic state is set to a safe state to ensure safe driving. In the present disclosure, when the self-regulator is initialized, if the acquisition of these critical logic state data from the database fails, all device states are set to a relatively safe state, and the traction power supply of the segment is in contact with the network state (no network, no power, guaranteed power) The locomotive will not enter the networkless and non-electrical area), and the segmentation of the segment is in a bad state (there is a bad shunt that is not confirmed to be idle, ensuring that the train will not enter the unsuccessful branching section where the idle is not confirmed), and the section is blocked (with blocking, Ensure that the train does not enter the blocking section) to improve the safety of the system operation.

Improve execution efficiency. When the self-regulator memory is not available and needs to be re-initialized, the critical logic state data that is persisted and saved from the database can be re-initialized. High reliability is achieved by storing critical logic states through the server.
