[0002] The control range of the interlocking system is one station and one interval, that is, the controlled interval is the large mileage interval. However, for the convenience of the operator on duty to master the train operation status in the interval, it is necessary to operate the display subsystem interface to simultaneously display the intervals on both sides of this station. Since the crossing equipment in the small mileage interval is not communicated with this station, the crossing equipment in the small mileage interval cannot be collected by this station, and it is impossible to complete the operation of the display subsystem interface at this station to display the status of the crossing in the small mileage interval, and the operator on duty cannot timely master the train operation status in the small mileage interval.

[0003] Take Figure 1 as an example. The existing computer system implementation method: The B station interlocking needs to communicate with all crossing equipment in the A station controlled interval (small mileage interval). The communication method is Ethernet communication, and the RSSP-I security protocol is adopted. The status of each interval crossing equipment at the crossing is received through the network to complete the function of collecting and displaying the equipment status of the crossing in the small mileage interval.

Obviously, the described embodiments are some, rather than all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts fall within the scope of protection of the present disclosure.

[0022] As Figure 2 shown, a method for transmitting the status of equipment at a level crossing in a section, the method includes: S201, the interlocking equipment at Station A and the level crossing in the section respectively establish a secure connection and receive the status information of the equipment at the level crossing; S202. The interlocking equipment at Station A processes the display of the crossing equipment status and the crossing logic related to the route according to the status information of the crossing equipment in the section. S203. The interlocking equipment at Station A packetizes the status information of the crossing equipment in the section to obtain packetized data. S204. The interlocking equipment at Station A transmits the packetized data for the display of the crossing equipment status at the interlocking equipment of Station B to the interlocking equipment of Station B. Among them, Station A is the control station for the small mileage section, and Station B is the control station for the large mileage section.

[0023] During specific implementation, it is introduced as follows: As Figure 3 shown, the method for displaying the crossing equipment in the small mileage section provided by the present disclosure: The computer interlocking equipment of the adjacent station (the control station for the small mileage section) sends the status of the crossing equipment in the small mileage section to the computer interlocking equipment of this station (the control station for the large mileage section) through the secure data network (Ethernet) according to the agreed application layer protocol, and the computer interlocking equipment of this station parses it to complete the display of the status of the crossing equipment in the small mileage section in the operation and indication subsystem. The connection method is as shown in the following figure: Among them, Station A is the control station for the small mileage section, and Station B is the control station for the large mileage section. Station B needs to complete the display of the equipment status of crossing AS1, crossing AS2, and crossing AS3 in the section in the operation and indication subsystem of this station.

[0024] The specific implementation process of the present disclosure: 1. The interlocking at Station A respectively establishes secure connections with crossing AS1, crossing AS2, and crossing AS3 in the section, receives the status information of the crossing equipment, and the received crossing information includes: crossing status, barrier status, crossing signal status, whether the crossing is closed due to line or equipment reasons, crossing section status (only applicable to section crossings), block request information and block status of the crossing (only applicable to section crossings), crossing interference and fault information, action fault information of the railing on the approach side of the crossing, crossing speed limit information, etc. The interlocking equipment at Station A completes the display of the crossing equipment status and the crossing logic related to the route according to the above information.

[0025] 2. The interlocking at Station A packetizes the status information of the crossing equipment in the section according to the agreed application layer communication protocol between interlockings, and stores the agreed data in the local data area.

[0026] 3. The interlocking at Station A transmits the data that needs to be sent in the local data area to the interlocking at Station B through Ethernet, using the UDP communication protocol and the RSSP-I secure communication protocol, and the application layer protocol is the protocol agreed between interlockings (described later).

[0027] 4. The interlocking system at Station B receives the data from the interlocking system at Station A via Ethernet, conducts data verification. After passing the verification, it unpacks the data according to the application protocol, parses the status of the crossing equipment in the section, and the operation indication subsystem completes the display of the status of the crossing equipment in the small mileage section.

[0028] The application protocol between interlockings mentioned in this disclosure includes: section direction information, section signal information, section block information, crossing equipment information in the section, etc. Now, the crossing equipment information in the section is mainly introduced. According to the information sent by the crossing equipment, the data transmission between interlockings needs to be in the form of virtual relays (i.e., digital signals). Due to the local display requirements, the barrier status does not need to be displayed for the crossing in the section, so the barrier status is not transmitted. The relay information to be transmitted and its meanings are shown in the following table:

[0029] The legend of the display status of the crossing equipment in the section and its corresponding meanings are as Figures 4 - 7 shown, where 1 represents the virtual relay being energized and 0 represents the virtual relay being de-energized. In the figure, the interference is divided into interference - level 1 and interference - level 2. The difference between the two is that interference - level 1 means that the crossing equipment cannot respond to the KT request normally, the speed limit is 15 km / h, and the crossing speed limit will not be increased until the interference is removed, and the CBI should not arrange the route passing through the crossing. Interference - level 2 means that the crossing can currently respond to the KT request normally, the current speed limit is 15 km / h, and the crossing speed limit will be increased when the speed - up conditions are met. The crossing status includes: crossing open status (KE), crossing closed status (KT), crossing open interruption status (KESZ), crossing closed interruption status (KTSZ), crossing closed hold status (KTH).

[0030] Based on the method proposed in this disclosure and the above - mentioned application protocol, the display of the status of the crossing equipment in the small mileage section has been realized. A certain interlocking station yard map is as Figure 8 shown, where AS279, AS293, and AS323 are the crossing equipment in the small mileage section.

[0031] A method for interlocking display of the status of crossing equipment in a section adopts the above - mentioned method for transmitting the status of crossing equipment in a section; After the interlocking equipment at Station B receives the packet data from the interlocking equipment at Station A, it conducts data verification. After passing the verification, it unpacks the data according to the communication protocol of the application layer between interlockings, parses the status information of the crossing equipment in the section, and conducts the display of the status of the crossing equipment in the section.

[0032] The A station of the present disclosure transmits the display information of the crossing equipment within its controlled section to the B station interlocking through the safety data network. Only the A station interlocking and the B station interlocking need to communicate over the network, reducing the number of communication nodes in the safety data network, reducing the amount of network transmission data, and ensuring the stability of the safety data network transmission; reducing the CPU operation pressure of the computer interlocking and effectively improving the stability of the computer interlocking equipment; completing the display of the status of the crossing equipment in the small mileage section, helping the duty officer to grasp the train operation status in the small mileage section in real time, and improving the line operation efficiency.
