Description

TECHNICAL FIELD

The present disclosure relates to a field of information processing technology, and more particularly, to a method and system for processing key logic states.

BACKGROUND

The Train operation Dispatching Command system, abbreviated as TDCS, mainly completes functions such as recording and analysis of dispatching command information, train number check, automatic reporting on being punctual or late, generation of statistics on late arrival and punctual arrival information, automatic drawing of operation diagram, issuing of dispatching command and plan, automatic generation of logbook, etc. The Centralized Traffic Control system, abbreviated as CTC can further complete automatic train route setting on schedule besides complete all the functions of the TDCS. The manual operation function of the station signal equipment is divided into two modes: decentralized self-discipline control and emergency station control.
An important function of the CTC is to track and store key states. The stability and security of storage of key states are of great significance to railway dispatching and command. In the prior art, a key state is stored in a data file. When a key state in the system is abnormal, the key state in the system is restored by reading a key state in the data file. Since the key state is real-time, it is necessary to synchronize the key state that has changed. Since the instability of the data file, the data is easily lost, and the file would possibly cannot be restored due to damage.
Therefore, a technique enabling process of key logic states that change in real time is needed.
CN 108032876 A1 aims to disclose a station trans-port dispatching method, comprising: receiving, by a plan processing module, station plan issued from a station plan management module; by the plan processing module, parsing the station plan into train route plan and issuing the train route plan to a route processing module; issuing, by the route processing module, the train route plan to a train arrival departure control module for processing; issuing, by the station plan management module, the station plan to a storage query module for storing.
EP 2264972 A1 aims to disclose a method for transmitting traffic data from a traffic-related field device to a traffic control center, to a traffic-related field device for transmitting traffic data to a traffic-related control center, and to a traffic-related control center for receiving traffic data from a traffic-related field device.

DETAILED DESCRIPTION

The exemplary embodiments of the present disclosure are described with reference to the drawings, however, the present disclosure may be embodied in many different forms and may not limited to the embodiments described herein. The embodiments are provided to disclose the present disclosure in detail and completely, and to fully convey the scope of the disclosure to those skilled in the art. The terms used in the exemplary embodiments and shown in the drawings are not intended to limit the disclosure. In the drawings, similar reference numerals are used for similar units/elements.
The terms (including technical terms) used herein are of the ordinary meaning for those skilled in the art, unless otherwise stated. In addition, it is to be understood that terms defined in commonly used dictionaries should be understood as having a meaning consistent with the context in the related art, and should not be interpreted as an idealized meaning or an over-interpreted meaning.
FIG. 1 is a flowchart illustrating a method for processing key logic states according to an embodiment of the present disclosure. In an implementation of the present disclosure, when a key logic state is changed, a latest state data of the key logic state is stored in a database. When a key logic state in the CTC becomes abnormal and needs to be restored, the stored key logic state is read from the database. If read of the key logic state is failed, the key logic state is set to a state that steers safely. In an implementation of the present disclosure, the key state is buffered in a memory of the autonomous machine and persistently stored in the database at the same time, and the key logic state stored in the memory of the autonomous machine is directly read during a manual operation process and the shunting route control, thereby improving the performance efficiency. When the key logic state stored in the memory of the autonomous machine is not available and needs to be reinitialized, the persistently stored data is obtained from the database, and the key logic state is reinitialized according to the technical solution of the present disclosure. In the technical solution of the present application, the synchronous processing of the key logic state and storing the key logical state in the database is more reliable and efficient. As shown in FIG. 1, a method 100 for processing key logic states begins at step 101.
Further, at step 101: obtaining a plurality of key logic states generated by a Centralized Traffic Control system during operation, determining operating devices associated with each of the plurality of key logical states, storing each key logical state together with an associated operating device in a corresponding manner into a database, and transmitting each key logic state to an autonomous machine.
Further, during the initialization according to the present disclosure, which key states (for example, whether a section is closed or not) each device should have is first determined, and then the database is queried for the current states of these key states (closed or open). Further, the present disclosure includes a process of initializing key logic states, which includes: first determining which key states each device should have, such as, for the device, whether there is a section closed or not, or whether there is a state of bad shunting, etc., and then searching in the database for the current states of these key states.
Further, the key logic states include states of a traction power contact network of a section, which include: being connected to network, being not connected to network, being powered, and being not powered. Further, the key logic states include states of bad shunting of a section, which include: no bad shunting, section occupied for the bad shunting, and section unoccupied for the bad shunting. Further, the key logic states include: open-close states of a section, which include: closed and open.
Further, the method further includes setting each of the plurality of key logic states by a user input or a state of a signaling device, transmitting the set key logic states to the autonomous machine for verification processing by the autonomous machine, and storing the key logic states synchronously into the database after the verification processing. According to the present disclosure, the key logic states are monitored by the system, and manually set by the user, or the key logic states may be changed jointly according to a state of a signaling device. In the present disclosure, the CTC system implements this function by setting and displaying, specifically, the user operates the key logic state at the CTC terminal, and transmits it to the autonomous machine for processing; after the operation is succeeded, the state is returned to the terminal for display, and store in the database synchronously.
Further, the method further includes deleting any of the plurality of key logic states by a user input.
Further, at step 102: determining whether the key logic state in the Centralized Traffic Control system is changed, obtaining, when a first key logic state is changed, a latest state data of the first key logic state and updating the first key logic state based on the latest state data, storing the updated first key logic state into the database, and transmitting the updated first key logic state to the autonomous machine.
Further, at step 103: searching, after a second key logic state in the autonomous machine becomes abnormal, in the database according to an operating device associated with the second key logic state to determine a second normal key logic state stored in the database, and transmitting the second normal key logic state to the autonomous machine to achieve synchronization of key logic states.
Further, during the abnormality restore according to the present disclosure, which key states (for example, whether a section is closed or not) each device should have is first determined, and then the database is queried for the current states of these key states (closed or open).
Further, each of the key logic states received is buffered by the autonomous machine.
Further, when the updated first key logic state is received by the autonomous machine, the first key logic state in a local buffer is replaced with the updated first key logic state, and the updated first key logic state is stored into the database.
Further, when the second normal key logic state is received by the autonomous machine, the second key logic state which is abnormal is replaced with the second normal key logic state. According to the present disclosure, in a normal state, when the key logic state is changed, the first key logic state in the autonomous machine is first updated, and then the first key logic state is stored into the database synchronously. When the second key logic state in the autonomous machine is failure and needs to be restarted, the last stored second key logic state is loaded from the database to replace the abnormal second key logic state in the autonomous machine.
Further, when read of the key logic state stored in the database is failed, the key logic state is set to a state that steers safely. According to the present disclosure, when the key logic state is changed, the latest key logic state is synchronously stored into the database in real time. When an abnormality occurs in the system and thus a restoration is needed, the key logic state data is read from the database. If read of the key logic state stored in the database is failed, the key logic state is set to a state that steers safely, to ensure safe driving. According to the present disclosure, during the initialization of the autonomous machine, if read of the key logic states stored in the database is failed, all the device states are set to relatively safe states, such as, states of a traction power contact network of a section (being not connected to network, and being not powered, ensuring that an electric train would not go to a section which is not connected to network and not powered), states of bad shunting of a section (section occupied for the bad shunting, ensuring that a train would not go to a occupied section with the bad shunting), open-close states of a section (closed, ensuring that a train would not go to a closed section), to improve the safety of the system operation.
For the key logic state of the present disclosure, it is buffered in a memory of the autonomous machine and persistently stored in the database at the same time, and the key logic state stored in the memory of the autonomous machine is directly read during a manual operation process and the shunting route control, thereby improving the performance efficiency. When the key logic state stored in the memory of the autonomous machine is not available and needs to be reinitialized, the persistently stored data may be obtained from the database for the reinitialization. High reliability is achieved by storing the key logic states in the server.
