Description
Technical Field
[0001] The present invention relates to the technical field of vehicle-to-vehicle safety communication, and in particular to a method and system for inter-subsystem communication transmission based on vehicle-to-vehicle communication. Background Art
[0002] In the "train autonomous operation system with vehicle-to-vehicle communication", trains apply to the trackside resource controller for various resources within the route, such as tracks, switches, and side rush areas, according to their own needs. When multiple trains share resources, it is easy to cause resource conflicts between trains, such as improper signal system resolution, causing safety accidents such as collisions. However, the key to solving this problem lies in ensuring the exclusivity of resources, that is, the resources are held by the train controller, or the resources are held by the trackside resource controller. At present, even if a safety communication protocol that meets the definition of EN50159 is used, because the communication between the train controller and the trackside resource controller will be intertwined, this method cannot solve the problem of resource exclusivity. Summary of the invention

[0017] Optionally, when each party sends corresponding code bits, the communicating party subtracts the resources sent but not confirmed from the newly received resources, and adds the resources held before the current communication cycle to obtain the resources that the communicating party ultimately owns in the current communication cycle, wherein the resources that the communicating party ultimately owns can verify the resource-exclusive communication transmission.

[0031] The present embodiment is described in detail below, and examples of the embodiment are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0032] In order to solve the technical problems in the background technology, the present invention provides a communication transmission method between subsystems based on vehicle-to-vehicle communication, namely, CDEQ (Communication Data with Exclusive Quantity, resource exclusive communication) method, the secure communication system used by the method includes subsystems WRC (Wayside Resource Controller, trackside resource controller), WTC (Wayside Train Controller, trackside train controller) and CC (Carborne Controller, carborne train controller). The method can ensure that the resource Quantity (application field, type is Boolean quantity, area, etc., hereinafter represented by Q) is not held by both communicating parties at the same time, so that the resource exchange between the subsystems is more concise and secure, which is conducive to improving the system security and availability.
[0033] The following describes the inter-subsystem communication transmission method and system based on vehicle-to-vehicle communication of this embodiment with reference to the accompanying drawings.
[0034] Figure 1 Flow chart of a method for inter-subsystem communication transmission based on vehicle-to-vehicle communication provided by an embodiment of the present invention. Figure 1 As shown, the method includes:
[0035] Step S1: Set several transmission fields.
[0036] Among them, several types of transmission fields include TTQ field, TTP field, TRQ field, TRP field, RTQ field, RTP field, RRQ field and RRP field, among which, the TTQ field indicates that the communication party sends resources to the communication other party; the TTP field indicates whether the communication party continues to send resources to the communication other party; the TRQ field indicates that the communication party requests resources from the communication other party; the TRP field indicates whether the communication party continues to request resources from the communication other party; the RTQ field indicates that the communication party receives resources sent by the communication other party; the RTP field indicates whether the communication party continues to receive resources sent by the communication other party; the RRQ field indicates that the communication party receives a request for resources from the communication other party; the RRP field indicates whether the communication party receives a request for resources from the communication other party.
[0037] Specifically, the CDEQ communication transmission method can set 8 transmission fields for the communicating parties, namely: TTQ field, whose type is a Boolean quantity or a region, etc., which indicates the resource Quantity sent by the communicating party to the communicating party; TTP field, whose type is a Boolean quantity, which indicates whether the communicating party continues to send resources Q to the communicating party when the user has configured a validity period. If this field is true, it means that it is valid within a validity period from the time when the TTP message is sent by the communicating party; TRQ field, whose type is a Boolean quantity or a region, etc., which indicates the resource Q requested by the communicating party to the communicating party; TRP field, whose type is a Boolean quantity, which indicates Indicates whether the communication party continues to request resource Q from the communication party. If this field is true, it means that it is valid within a validity period starting from the time when the communication party sends the TRP message; RTQ field, type is a Boolean quantity or a range, etc., which indicates the resource Q sent by the other party received by the communication party; RTP field, type is a Boolean quantity, which indicates whether the communication party continues to receive resource Q sent by the communication party; RRQ field, type is a Boolean quantity or a range, etc., which indicates the resource Q requested by the communication party to the communication party; RRP field, type is a Boolean quantity, which indicates whether the communication party receives the resource Q continuously from the communication party.
[0038] Step S2: The communicating party and the communicating party configure the resource transmission request item and the validity period item to respectively determine the corresponding transmission fields and the code bits that each party needs to send.
[0039] Among them, the resource transmission request item is configured to configure whether the communication party needs to send a request to the communication party when the communication party and the communication party exchange resources; the validity period item is configured to configure whether the resources sent by the communication party received by the communication party have a validity period.
[0040] Specifically, both parties can configure the protocol stack, including the Request, i.e., resource transmission request item, and the Duration, i.e., validity period item. Request is configured as a Boolean value, indicating whether the communication party needs to send a request to the other party when exchanging resources with the communication party; Duration is configured as a Boolean value, indicating whether the resources sent by the communication party received by the communication party have a validity period. When the resources are within the validity period, the communication party's users can use the resources normally. If the validity period is exceeded, the communication party's users can no longer use the resources.
[0041] In this embodiment, the communicating parties can configure the Request and Duration, wherein different request and validity period configurations will determine different transmission fields and code bits. Figure 2This is a schematic diagram of the configuration commonly selected by the CC side when the CC interacts with WRC resources. The figure specifically includes a configuration area and a result area. Among them, the configuration area is the configuration combination of the communication party and the communication party regarding Request and Duration, and the result area is the result of whether the eight field bits of the communication party are included in the communication under different configuration conditions. Among them, the configuration area in the highlighted column is the configuration of the CC side in the CC-WRC communication link, which means that the code bits sent by the CC side to the WRC are TTQ, TRQ and TRP, and the code bits sent by the WRC on the CC side are RTQ, RTP and RRQ, that is, when the WRC allocates resources to the CC, there is a validity period, but when the CC releases resources to the WRC, there is no validity period.
[0042] In one embodiment of the present invention, for the TTQ field, if the communication partner configures a corresponding resource transmission request item, the method also includes: taking the intersection of the resources sent by the communication party and the resources requested by the communication partner, and determining the TTQ field to be sent to send the corresponding code position.
[0043] Specifically, for TTQ, if the communication partner configures a request, the resource Q that the communication user wants to send needs to be intersected with the resource RRQ requested by the communication partner to form TTQ before sending. That is, if the communication partner does not request the relevant resources, the communication party will send the default value of the resource (that is, the restricted state of the corresponding resource). Through this operation, the protocol stack can integrate the resource Q sent to the other party.
[0044] In one embodiment of the present invention, for the TTP field, if the communication partner has configured a corresponding resource transmission request item, the method also includes: the communication party takes the intersection of the Boolean value of the TTP field indicating whether to continuously issue resources and the RRP field sent by the communication partner indicating whether to continuously request resources, and determines the TTP field to be issued to issue the corresponding code position.
[0045] Specifically, for TTP, if the communication partner configures a request, the Boolean value of whether the user of the communication party wants to continue to send Q needs to be intersected with the RRP sent by the communication partner whether to continue to request resource Q, and finally form TTP and then send it. It specifically indicates whether the communication party continues to send resource Q in response to the communication partner's continuous request for resource Q. In this embodiment, through this operation, the protocol stack can integrate the resource Q sent to the other party.
[0046] In one embodiment of the present invention, for the TRP field, if the communication party can provide the resources requested by the communication party, the TRP field is determined to be true, wherein the TRP field is true, which means that it is valid within a validity period starting from the time the communication party sends the TRP message.
[0047] Specifically, for TRP, as long as the resources that the communicating user wants to request are not empty, TRP is true; otherwise, TRP takes the value of false.
[0048] Step S3: Each party sends corresponding code bits to achieve resource-exclusive communication transmission.
[0049] When each party sends the corresponding code bits, the communicating party will subtract the resources sent out but not confirmed from the newly received resources, and add the resources held before the current communication cycle to obtain the resources that the communicating party ultimately owns in the current communication cycle. The resources that the communicating party ultimately owns can verify the resource-exclusive communication transmission, that is, the final resource ownership result shows that the communicating parties will not jointly hold the said resources.
[0050] Figure 3 The resource exchange process between WRC and CC for PBZ (Point Blade Zone) resources is described. The CC side use period is marked as A, and the WRC use period is marked as B. Among them, m corresponds to CC's PBZ authorization is true, n corresponds to CC's PBZ authorization is false, p corresponds to WRC's PBZ authorization is true, and q corresponds to WRC's PBZ authorization is false, that is, m, n, p and q only correspond to Figure 3 The icons in the upper right corner do not represent a specific quantity value.
[0051] In this specific example, from the perspective of CC cycle, the resource exchange process is described as follows:
[0052] Under initial conditions, the PBZ resources are on the WRC side, and the CC side does not hold PBZ resources.
[0053] In the A1 cycle, the CC sends a confirmation message for the B9 cycle of the WRC. At this time, the resources held by the CC side are the existing resources n minus the resources n that have been sent but not confirmed, and the resources held are still n.
[0054] In cycle A2, CC receives a message with cycle number B10 from WRC. The resources held by CC at this time are the newly received resources q from WRC minus the resources n carried in the message sent by CC in cycle A1 but not confirmed by WRC plus the resources n held by CC before this cycle. The final resources held by CC are still n.
[0055] In the A3 cycle, CC sends a confirmation message for the B10 cycle of WRC. At this time, the resources held by CC are the existing resources n minus the resources n that have been issued but not confirmed, and the resources held are still n. At this time, because the NOCR (resource demand area) of CC intersects with the PBZ, CC needs the resources of PBZ to pass the switch, so CC sends a request TRQ for resources.
[0056] In the A4 cycle, CC receives a message with cycle number B12 from WRC. The resources held by CC at this time are the newly received resources q from WRC minus the resources n carried in the message sent by CC in the A3 cycle but not confirmed by WRC, plus the resources n held by CC before this cycle. The final resources held by CC are still n.
[0057] In the A5 cycle, the CC sends a confirmation message for the B12 cycle of the WRC. At this time, the resources held by the CC side are the existing resources n minus the resources n that have been sent but not confirmed, and the resources held are still n.
[0058] In the A6 cycle, CC receives a message with cycle number B14 from WRC. The resources held by CC at this time are the resources p newly received from WRC minus the resources n carried in the message sent by CC in the A5 cycle but not confirmed by WRC, plus the resources n held by CC before this cycle, so the final resources held by CC are m.
[0059] In the A7 cycle, CC sends a confirmation message for the B14 cycle of WRC. At this time, the resources held by CC are the existing resources m minus the resources m that have been issued but not confirmed, and the resources held are n. At this time, the train has cleared the PBZ area, and CC no longer needs the resources of PBZ, so it no longer sends the resource TRQ requested from the other party, and at the same time sends the resource TTQ released to the other party.
[0060] In cycle A8, CC receives a message with cycle number B16 from WRC. The resources held by CC at this time are the resources p newly received from WRC minus the resources m carried in the message sent by CC in cycle A7 but not confirmed by WRC, plus the resources n held by CC before this cycle. The final resources held by CC are n.
[0061] In the A9 cycle, the CC sends a confirmation message for the B16 cycle of the WRC. At this time, the resources held by the CC side are the existing resources n minus the resources m that have been sent but not confirmed, and the resources held are n.
[0062] In cycle A10, CC receives a message with cycle number B18 from WRC. The resources held by CC at this time are the newly received resources q from WRC minus the resources m carried in the message sent by CC in cycle A9 but not confirmed by WRC, plus the resources n held by CC before this cycle. The final resources held by CC are n.
[0063] From the perspective of the WRC cycle, the resource exchange process is described as follows:
[0064] Under initial conditions, the PBZ resources are on the WRC side, and the CC side does not hold PBZ resources.
[0065] In the B10 cycle, the WRC sends a confirmation message for the A0 cycle of the CC. At this time, the resources held by the WRC side are the existing resources p minus the resources q that have been sent but not confirmed, and the resources held are still p.
[0066] In cycle B11, WRC receives a message with cycle number A1 from CC. The resources held by WRC at this time are the newly received resources n from CC minus the resources q contained in the message sent by WRC in cycle B10 but not confirmed by CC, plus the resources p held by WRC before this cycle. The final resources held by WRC are still p.
[0067] In the B12 cycle, the WRC sends a confirmation message for the A1 cycle of the CC. At this time, the resources held by the WRC side are the existing resources p minus the resources q that have been sent but not confirmed, and the resources held are still p.
[0068] In cycle B13, WRC receives a message with cycle number A3 from CC. The resources held by WRC at this time are the newly received resources n from CC minus the resources q contained in the message sent by WRC in cycle B12 but not confirmed by CC, plus the resources p held by WRC before this cycle. The final resources held by WRC are still p.
[0069] In the B14 cycle, WRC sends a confirmation message for CC's A3 cycle. At this time, the resources held by WRC are the existing resources p minus the resources p that have been issued but not confirmed, and the held resources become q. At this time, because the message sent by CC in the A3 cycle contains its application TRQ for resource Q, WRC will send the released resource TTQ.
[0070] In cycle B15, WRC receives a message with cycle number A5 from CC. The resources held by WRC at this time are the newly received resources n from CC minus the resources p contained in the message sent by WRC in cycle B14 but not confirmed by CC, plus the resources q held by WRC before this cycle. The final resources held by WRC are still q.
[0071] In the B16 cycle, the WRC sends a confirmation message for the A5 cycle of the CC. At this time, the resources held by the WRC side are the existing resources q minus the resources p that have been sent but not confirmed, and the resources held are still q.
[0072] In cycle B17, WRC receives a message with cycle number A7 from CC. The resources held by WRC at this time are the newly received resources m from CC minus the resources p carried by the message sent by WRC in cycle B16 but not confirmed by CC, plus the resources q held by WRC before this cycle, and the final resources held by WRC are still q. Although WRC has received the resource Q returned from CC at this time, because there is a resource Q sent but not confirmed, it can be known through calculation that the final resources held by WRC are q.
[0073] In the B18 cycle, WRC sends a confirmation message for CC's A7 cycle. At this time, the resources held by WRC are the existing resources q minus the resources q that have been issued but not confirmed, and the resources held are still q. At this time, because CC no longer needs PBZ resources, WRC no longer sends PBZ resources.
[0074] In cycle B19, WRC receives a message with cycle number A9 from CC. The resources held by WRC at this time are the newly received resources m from CC minus the resources q carried in the message sent by WRC in cycle B18 but not confirmed by CC, plus the resources q held by WRC before this cycle. The final resources held by WRC are still p.
[0075] From the above process and Figure 3 It can be seen that during the resource exchange process between CC and WRC, the two parties will not jointly hold the PBZ resources in each cycle, and at most one party will hold them, thus ensuring the safe allocation of resources.
[0076] Furthermore, the present invention also provides a computer-readable storage medium having a computer program stored thereon, and when the computer program is executed by a processor, the above-mentioned inter-subsystem communication transmission method based on vehicle-to-vehicle communication is implemented.
[0077] Furthermore, the present invention also provides an electronic device, including a processor and a memory, wherein the memory stores a computer program, and when the computer program is executed by the processor, the above-mentioned inter-subsystem communication transmission method based on vehicle-to-vehicle communication is implemented.
[0078] Figure 4 FIG. 1 is a block diagram of a subsystem communication transmission system based on vehicle-to-vehicle communication provided by an embodiment of the present invention. Figure 4As shown, the inter-subsystem communication transmission system 10 based on vehicle-to-vehicle communication includes: a setting module 11, a configuration module 12 and a sending module 13, wherein the setting module 11 is used to set several transmission fields; the configuration module 12 is connected to the setting module 11, and the configuration module 12 is used to configure the resource transmission request item and the validity period item to determine the transmission field that the communication party or the communication party needs to send, so as to determine the code position that needs to be sent; the sending module 13 is used to send the code position to realize resource exclusive communication transmission.
[0079] Among them, several types of transmission fields include TTQ field, TTP field, TRQ field, TRP field, RTQ field, RTP field, RRQ field and RRP field, among which, the TTQ field indicates that the communication party sends resources to the communication other party; the TTP field indicates whether the communication party continues to send resources to the communication other party; the TRQ field indicates that the communication party requests resources from the communication other party; the TRP field indicates whether the communication party continues to request resources from the communication other party; the RTQ field indicates that the communication party receives resources sent by the communication other party; the RTP field indicates whether the communication party continues to receive resources sent by the communication other party; the RRQ field indicates that the communication party receives a request for resources from the communication other party; the RRP field indicates whether the communication party receives a request for resources from the communication other party.
[0080] In one embodiment of the present invention, when the configuration module 12 configures the resource transmission request item, it is specifically used to: configure whether the communication party needs to send a request to the communication party during the resource exchange process between the communication party and the communication party. When the configuration module 12 configures the validity period item, it is specifically used to configure whether the resource sent by the communication party received by the communication party has a validity period.

[0082] In one embodiment of the present invention, for the TTP field, if the corresponding resource transmission request item is configured through the configuration module 12, the configuration module 12 also takes the intersection of the Boolean value of the TTP field indicating whether the communication party continues to send resources and the RRP field sent by the communication party indicating whether to continue to request resources, and determines the TTP field to be sent to send the corresponding code position.

[0084] In summary, the present invention sets several transmission fields, and then the communicating party and the communicating party configure the resource transmission request items and validity period items to determine the transmission fields to be sent by each party respectively, and send out the corresponding code bits. The above configuration can be used to achieve exclusive resource transmission, ensuring that resources will not be occupied at the same time when the communicating parties exchange them, thereby ensuring system security. In addition, the present invention integrates the transmission field resources through this communication method, which can improve the efficiency of users' use of the transmission fields.

A subsystem communication transmission system based on vehicle-to-vehicle communication, characterized in that: include: A setting module, used to set several types of transmission fields; the several types of transmission fields include TTQ field, TTP field, TRQ field, TRP field, RTQ field, RTP field, RRQ field and RRP field, wherein the TTQ field indicates that the communication party sends resources to the communication party; the TTP field indicates whether the communication party continues to send resources to the communication party; the TRQ field indicates that the communication party requests resources from the communication party; the TRP field indicates whether the communication party continues to request resources from the communication party; the RTQ field indicates that the communication party receives resources sent by the communication party; the RTP field indicates whether the communication party continues to receive resources sent by the communication party; the RRQ field indicates that the communication party receives a request for resources from the communication party to the communication party; the RRP field indicates whether the communication party receives a request for resources from the communication party to the communication party; a configuration module connected to the setting module, the configuration module is used to configure the resource transmission request item, including: when the communication party and the communication party exchange resources, whether the communication party needs to send a request to the communication party; configure the validity period item, including: whether the resource sent by the communication party to the communication party has a validity period; for the TTQ field, if the communication party has configured the corresponding resource transmission request item, the resource sent by the communication party and the resource requested by the communication party are intersected, and the TTQ field to be sent is determined to send the corresponding code position; for the TTP field, if the communication party has configured the corresponding resource transmission request item, the communication party will take the intersection of the Boolean value of the TTP field indicating whether to continue to send resources and the RRP field sent by the communication party indicating whether to continue to request resources, and determine the TTP field to be sent to send the corresponding code position; for the TRP field, if the communication party can provide the resource requested by the communication party, the TRP field is determined to be true, wherein the TRP field is true, which means that it is valid within a validity period starting from the time when the communication party sends the TRP message; The sending module is used to send the code bit. The communicating party subtracts the resources sent but not confirmed from the newly received resources, and adds the resources held before the current communication cycle to obtain the resources that the communicating party ultimately owns in the current communication cycle. The resources that the communicating party ultimately owns can verify the resource-exclusive communication transmission.
