Description

Technical Field

[0002] The control range of the interlocking system is one station and one section, that is, the controlled section is a large mileage section. However, in order to facilitate the duty officer to grasp the driving status of the section, it is necessary to operate the display subsystem interface to simultaneously display the sections on both sides of this station. Since the crossing equipment in the small mileage section has not communicated with this station, this station cannot collect data from the crossing equipment in the small mileage section, and cannot complete the operation of the display subsystem interface at this station to display the crossing status of the small mileage section. The duty officer cannot grasp the driving status of the small mileage section in real time.

[0003] by Figure 1 For example, in the existing computer system implementation, station B's interlocking system needs to communicate with all crossing equipment within the section controlled by station A (a short-distance section). This communication is done via Ethernet, using the RSSP-I security protocol. The network receives the status of each crossing equipment section, completing the equipment status collection and display function for the short-distance sections. However, this solution presents challenges: If there are a large number of crossing equipment sections, this places high demands on the CPU computing power of the computer interlocking equipment.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0053] like Figure 2 As shown, a method for transmitting the status of a section crossing device includes:

[0054] S201: The interlocking equipment at station A establishes a secure connection with the section crossing and receives the status information of the section crossing equipment;

[0055] S202, the interlocking equipment at station A performs crossing equipment status display and route-related crossing logic processing based on the section crossing equipment status information;

[0056] S203, the interlocking equipment at station A packages the status information of the section crossing equipment to obtain packaged data;

[0057] S204, the interlocking device at station A transmits the packaged data for displaying the status of the road crossing equipment of the interlocking device at station B to the interlocking device at station B;

[0058] Among them, Station A is a small mileage interval control station, and Station B is a large mileage interval control station.

[0059] The specific implementation is as follows:

[0060] like Figure 3 As shown, the present disclosure provides a method for displaying equipment at short-distance level crossings: the computer interlocking equipment at a neighboring station (a short-distance level crossing control station) transmits the status of the short-distance level crossing equipment to the computer interlocking equipment at the local station (a long-distance level crossing control station) via a secure data network (Ethernet) according to an agreed application layer protocol. The local computer interlocking equipment then interprets the information and displays the status of the short-distance level crossing equipment in the operation and display subsystem. The connection diagram is shown below: Station A is a short-distance level crossing control station, and Station B is a long-distance level crossing control station. Station B needs to display the equipment status of level crossings AS1, AS2, and AS3 in its own operation and display subsystem.

[0061] The specific implementation process of this disclosure:

[0062] 1. Station A's interlocking system establishes secure connections with AS1, AS2, and AS3, respectively, to receive status information from each of the following: crossing status, barrier status, signal status, whether the crossing is closed due to line or equipment issues, crossing section status (applicable only to section crossings), crossing blockage request information and blockage status (applicable only to section crossings), crossing interference and fault information, entry-side barrier actuation fault information, and crossing speed limit information. Based on this information, the station A interlocking system displays crossing equipment status and performs route-related crossing logic processing.

[0063] 2. The interlocking at station A packages the status information of the section crossing equipment according to the agreed interlocking application layer communication protocol and stores the agreed data in the local data area.

[0064] 3. Station A interlocking transmits the data to be sent in the local data area to Station B interlocking via Ethernet, using UDP communication protocol and RSSP-I secure communication protocol. The application layer protocol is the protocol agreed upon between interlocking (described later).

[0065] 4. The interlocking station B receives the data from the interlocking station A via Ethernet and performs data verification. After the verification is passed, the data is unpacked according to the application protocol and the status of the section crossing equipment is parsed. The operation display subsystem completes the status display of the short-mileage section crossing equipment.

[0066] The interlocking application protocol mentioned in this disclosure includes information about section direction, section signals, section zones, and section crossing equipment. This section primarily discusses section crossing equipment information. Based on the information sent by the crossing equipment, the interlocking protocol uses virtual relays (i.e., switching values) for data transmission. Due to local display requirements, the section crossings do not require the display of barrier status, so barrier status is not transmitted. The relay information that needs to be transmitted and its meaning are shown in the following table:

[0067]

[0068] The legend of the display status of the section crossing equipment and its corresponding meaning are as follows Figure 4-Figure 7As shown, 1 represents the virtual relay being pulled up, and 0 represents the virtual relay being dropped. In the figure, 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 normally to KT requests, the speed limit is 15km / h, the speed limit at the crossing will not be increased until the interference is removed, and CBI should not arrange the approach through the crossing. Interference-level 2 means that the crossing can currently respond normally to KT requests, the current speed limit is 15km / h, and the speed limit at the crossing will be increased after the speed increase 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), and crossing closed hold status (KTH).

[0069] According to the method proposed in this disclosure and the above-mentioned application protocol, the status display of the equipment at the small-mileage section crossing has been realized. The diagram of a certain interlocking station is as follows: Figure 8 As shown, AS279, AS293, and AS323 are short-distance crossing equipment.

[0070] A method for interlocking display of equipment status at a section crossing, using the above-mentioned method for transmitting equipment status at a section crossing;

[0071] After the interlocking device at station B receives the packaged data from the interlocking device at station A, it performs data verification. After the verification is passed, it unpacks the data according to the interlocking application layer communication protocol, parses out the status information of the section crossing equipment, and displays the status of the section crossing equipment.

[0072] In the present invention, station A transmits the display information of the crossing equipment within the control section of this station to the interlocking station B through the safety data network. Only the interlocking station A and the interlocking station B need to communicate over the network, which reduces the number of communication nodes in the safety data network, reduces the amount of network transmission data, and ensures the stability of the safety data network transmission; reduces the CPU computing pressure of the computer interlocking, and effectively improves the stability of the computer interlocking equipment; completes the status display of the crossing equipment in the short mileage section, helps the operator to grasp the driving status of the short mileage section in real time, and improves the line operation efficiency.

[0076] The interlocking equipment at station A packages the status information of the section crossing equipment to obtain packaged data;

[0077] The interlocking device at station A transmits the packaged data used for displaying the status of the crossing equipment at station B to the interlocking device at station B;

[0078] Among them, Station A is a small mileage interval control station, and Station B is a large mileage interval control station.

[0081] The processor 1001 is configured to implement the aforementioned method for transmitting the status of a section crossing device, or the aforementioned method for displaying the status of a section crossing device in a linked manner, when executing the computer program stored in the memory 1003 .

[0082] A computer-readable storage medium stores a computer program. When the computer program is executed by a processor, it implements the above-mentioned method for transmitting the status of a section crossing device, or implements the above-mentioned method for chain displaying the status of a section crossing device.

[0083] The computer-readable storage medium may be included in the device / apparatus described in the above embodiments, or may exist independently without being incorporated into the device / apparatus. The computer-readable storage medium carries one or more programs that, when executed, implement the method according to the embodiments of the present disclosure.
