[0002] In China's railways, there are multiple levels of train operation control systems. The same railway line may be divided into multiple train control level sections. The conversion between different train control levels is achieved through the inter-level conversion balise groups set on the line. The distances required for trains to complete inter-level conversion between different inter-level conversion balise groups also vary greatly. The neutral section refers to the non-powered area of the catenary between two power supply sections in the AC traction electrified section. It is necessary to control the running state of the train through ground balises at a certain safe distance in advance to ensure that the train can pass through the neutral section safely. However, in some special cases, it may be necessary to control the train to cross the neutral section while performing inter-level conversion, and the distance between the demarcation point of completing inter-level conversion and the neutral section is difficult to meet the normal distance requirements for controlling the train to cross the neutral section.

[0037] Embodiment 1

[0038] Figure 1A This is a flowchart of an inter - level conversion method based on wireless pre - warning of phase - separation positions provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation where a train performs inter - level conversion while passing through a phase - separation section. This method can be executed by an inter - level conversion device based on wireless pre - warning of phase - separation positions. The inter - level conversion device based on wireless pre - warning of phase - separation positions can be implemented in the form of hardware and / or software, and can be configured in an electronic device, specifically in an inter - level conversion platform. As Figure 1A shown, this method is applied to the inter - level conversion platform and includes:

[0039] S110. Obtain the pre - warning information sent by the radio block center, perform information parsing on the pre - warning information, and obtain a pre - warning parsing result.

[0040] Among them, the radio block center can be a facility for realizing wireless control and monitoring of trains, and specifically, real-time information exchange with trains can be realized through wireless communication technology. Among them, the wireless communication technology can include radio communication, data link communication, and satellite positioning systems, etc.

[0041] Among them, the advance notice information can be information for notifying the train to perform a control level conversion, and can also be information for notifying the train to pass through the neutral section and perform mutual conversions between control levels.

[0042] The advance notice analysis result can be to notify the train to perform a control level conversion, or to notify the train to pass through the neutral section and perform mutual conversions between control levels.

[0043] S120. If the advance notice analysis result simultaneously includes the train level conversion advance notice information and the train neutral section passing advance notice information, determine the balise on the train running route; among them, the train level conversion advance notice information and the train neutral section passing advance notice information can be generated by the radio block center when it monitors that the distance between the train control level conversion area and the train neutral section passing area is less than the preset safety distance threshold. Among them, the train level conversion advance notice information can specifically be to notify that a train controlled by the CTCS-3 level system is to be converted to be controlled by the CTCS-2 level system. The train neutral section passing advance notice information can specifically be to notify the train to perform automatic neutral section passing.

[0044] Among them, the balise can be a device for receiving and responding to the wireless signal sent by the train and enhancing the communication between the train and the control center, and specifically can be used for train positioning, data transmission, and fault diagnosis and maintenance.

[0045] Among them, the preset safety distance threshold can specifically be the minimum line distance that can ensure the train to complete the control level conversion and can realize the automatic neutral section passing control of the train. Exemplarily, the safety distance threshold can be 1000 meters. Specifically, it can be preset by technicians according to the actual situation, or can be automatically set by the train control according to the train operation environment. This embodiment does not make specific limitations.

[0046] Exemplarily, as Figure 1B shown in the schematic diagram of the balise layout, where the F line section is connected to Station D via the a line uplink connecting line and the a line downlink connecting line respectively, and when the train passes through the F line section and Station D, it is controlled by the CTCS-3 level system.

[0047] Specifically, it can be when the train is on the downlink connecting line of Line A and is traveling from Station D to the F line section. The radio block center monitors that the train needs to complete the conversion of the train control level before reaching neutral section 1 and realizes the train control process of automatically passing through neutral section 1. The distance between the area where the train control level can be converted and the area where the train can automatically pass through the neutral section is less than the preset safety distance threshold. Exemplarily, it can be monitored that the distance for controlling the train to complete the control level conversion is 400 meters, and the remaining distance to the neutral section after the train completes the control level conversion is 450 meters. The sum of the two distances is less than 1000 meters. Then, the radio block center can simultaneously send the train level conversion advance notice information and the train neutral section passing advance notice information to the level conversion platform.

[0048] Furthermore, the level conversion platform can determine the balise on the ground that can complete the train level conversion and automatically realize the neutral section passing control in the traveling direction of the train on the downlink connecting line of Line A according to the train level conversion advance notice information and the train neutral section passing advance notice information sent by the radio block center.

[0049] S130. Select the target balise from the ground balises according to the train level conversion advance notice information and the train neutral section passing advance notice information, and send the balise identification of the target balise to the radio block center for the radio block center to determine the target balise based on the target balise identification and perform the balise configuration operation on the target balise to control the target balise to perform the level conversion advance notice and the neutral section passing advance notice.

[0050] Among them, the target balise can be a ground balise whose installation position distance meets the preset safety distance threshold. Continuing with the above example, the target balises can be Balise 1, Balise 2, and Balise 3.

[0051] Specifically, the balise configuration for the target balise can be to configure the target balise as a level conversion balise and a neutral section passing balise, and the level conversion advance notice of the train control level conversion and the advance notice of the train passing through the neutral section can be realized through the target balise.

[0052] Among them, the level conversion balise can include a level advance notice balise and a level conversion balise. The level advance notice balise can specifically be a ground balise used to advance notice the train of the level conversion information; the level conversion balise can specifically be a ground balise set at the level conversion demarcation point to send an unconditional level conversion command to the train to force the train to complete the level conversion after the level conversion demarcation point. Among them, the neutral section passing balise can be a ground balise used to advance notice the train of the neutral section passing information and realize the train's automatic passing through the neutral section.

[0053] Optionally, according to the train grade conversion notice information and the train passing neutral section notice information, target balises are selected from ground balises, including: selecting grade conversion balises and passing neutral section balises that meet the distance judgment condition from ground balises according to the train grade conversion notice information and the train passing neutral section notice information; selecting notice balises and conversion balises from the grade conversion balises according to the train grade conversion notice information.

[0054] Among them, the distance judgment condition can specifically judge whether the distance between the ground balise and the neutral section meets the distance for realizing automatic train passing neutral section control, or can also be to judge whether the distance between the notice balise and the conversion balise meets the distance for completing the train grade conversion.

[0055] Continuing with the above example, if the distance for realizing automatic train passing neutral section control is 1000 meters, balise 1 can be determined as the passing neutral section balise; if the distance for completing the train grade conversion is 400 meters, balise 2 and balise 3 can be determined as the grade conversion balises.

[0056] Specifically, selecting the notice balise and the conversion balise can specifically divide the determined grade conversion balises into notice balises and conversion balises according to the train running route and direction, and the execution process of the train grade conversion. Exemplarily, if the train running route is the a-road first downlink connecting line and the running direction is from Station D to the F line section, then according to the train grade conversion notice information, balise 2 can be determined as the notice balise, and balise 3 can also be determined as the conversion balise.

[0057] In an optional solution of this embodiment, it can be combined with one or more optional solutions in this embodiment. Optionally, if the notice parsing result only contains the train grade conversion notice information, determine the ground balises on the train running route, and select grade conversion balises from the ground balises according to the train grade conversion notice information; the grade conversion balises include notice balises and conversion balises.

[0058] Specifically, only containing the train grade conversion notice information can indicate that the distance between the train control grade conversion area and the train passing neutral section area is greater than the preset safety distance threshold. The grade conversion platform can directly select grade conversion balises that meet the distance for the train to complete the grade conversion from the ground balises in the train running route and direction according to the grade conversion notice information issued by the radio block center, and complete the conversion of the train control grade according to the notice balises and conversion balises included in the grade conversion balises.

[0059] In the technical solution of the embodiment of the present invention, by obtaining the advance notice information sent by the radio block center, parsing the advance notice information to obtain an advance notice parsing result; if the advance notice parsing result contains both train level conversion advance notice information and train neutral section passing advance notice information at the same time, determine the balises on the train's driving route; select target balises from the balises according to the train level conversion advance notice information and the train neutral section passing advance notice information, and send the balise identification of the target balises to the radio block center for the radio block center to determine the target balises based on the target balise identification and perform balise configuration operations on the target balises to control the target balises to perform level transition advance notice and neutral section passing advance notice. This solution can, according to the distance between the area where the train performs level transition and the area where the train passes through the neutral section monitored, when the preset safety distance threshold is not met, realize the automatic control of the train's level transition and neutral section passing through wireless communication technology, so as to improve the intelligent control of the train and the safety during the driving process.

[0060] Embodiment 2

[0061] Figure 2 FIG. is a flowchart of a level transition method based on wireless advance notice of neutral section position provided by Embodiment 2 of the present invention. This embodiment is applicable to the situation where the train passes through the neutral section while performing a level transition. This method can be executed by a level transition device based on wireless advance notice of neutral section position. The level transition device based on wireless advance notice of neutral section position can be implemented in the form of hardware and / or software. The level transition device based on wireless advance notice of neutral section position can be configured in an electronic device, specifically in a radio block center. As Figure 2 shown, this method is applied to a radio block center and includes:

[0062] S210. When it is monitored that the train has a level transition requirement and at the same time it is monitored that the distance between the train control level conversion area and the train neutral section passing area is less than the preset safety distance threshold, generate advance notice information including train level conversion advance notice information and train neutral section passing advance notice information.

[0063] Among them, the level transition requirement may be that the train needs to pass through different driving routes with a specified train control system. Exemplarily, it may be that the train will be converted from a train controlled by the CTCS-3 level system to a train controlled by the CTCS-2 level system 800 meters after leaving the station and travel a certain distance. Specifically, the level transition requirement may be automatically initiated according to the route information of the train's travel, or may be manually initiated by technicians in advance. This embodiment does not make specific limitations.

[0064] Among them, the train control level conversion area may specifically be the route area of the train from receiving the control level conversion advance notice information until the control level conversion is completed. The train neutral section passing area may be the route area that gives an advance notice to the train of passing through the neutral section to the neutral section area.

[0065] Exemplarily, if the preset safe distance threshold can be 1000 meters, and the monitored distance between the train control level conversion area and the train neutral section passing area can be 750 meters, it can be determined that the preset safe distance threshold is not met. The radio block center can then generate a pre-warning message containing the train level conversion pre-warning information and the train neutral section passing pre-warning information and send it to the level conversion platform.

[0066] S220. Send a pre-warning message to the level conversion platform. When the level conversion platform receives the pre-warning message, it parses the pre-warning message to obtain a pre-warning parsing result. If the pre-warning parsing result contains both the train level conversion pre-warning information and the train neutral section passing pre-warning information, determine the balises on the train's driving route, and based on the train level conversion pre-warning information and the train neutral section passing pre-warning information, select target balises from the balises and send the balise identifiers of the target balises to the radio block center.

[0067] Specifically, after receiving the pre-warning message containing the train level conversion pre-warning information and the train neutral section passing pre-warning information sent by the radio block center, the level conversion platform can select target balises on the train's driving route according to the route distance of the train from receiving the control level conversion pre-warning information until completing the control level conversion, and the distance required to achieve automatic train neutral section passing control. Exemplarily, as Figure 1B shown in the schematic diagram of the balise layout on the ground, if the distance required to achieve automatic train neutral section passing control can be 1000 meters, and the distance required for the train to complete the level conversion is 400 meters, then balise 1, balise 2, and balise 3 can be selected as target balises from the balises. The balise identifiers of the target balises can also be sent to the radio block center.

[0068] S230. Determine the target balises based on the target balise identifiers and perform balise configuration operations on the target balises according to the train level conversion pre-warning information and the train neutral section passing pre-warning information, so as to control the target balises to perform level conversion pre-warning and neutral section passing pre-warning.

[0069] Among them, the target balises include level conversion balises and neutral section passing balises; the level conversion balises include pre-warning balises and conversion balises; among them, the level conversion balises and the neutral section passing balises are selected by the level conversion platform from the ground balises based on the distance judgment condition according to the train level conversion pre-warning information and the train neutral section passing pre-warning information; the pre-warning balises and the conversion balises are selected by the level conversion platform from the level conversion balises based on the level conversion pre-warning information.

[0070] Optionally, according to the train grade conversion notice information and the train neutral section passing notice information, perform a transponder configuration operation on the target transponder to control the target transponder to perform inter-level notice and neutral section passing notice, including: sending the train grade conversion notice information to the grade conversion transponder and the train neutral section passing notice information to the neutral section passing transponder according to the preset grade safety distance, so that the notice transponder in the grade conversion transponder performs the grade conversion notice operation and the grade transponder performs the grade conversion operation, and the neutral section passing transponder performs the train neutral section passing notice operation.

[0071] Among them, the grade safety distance can be the route distance that can ensure the train to complete the control grade conversion and achieve automatic neutral section passing. Exemplarily, the grade safety distance for automatic neutral section passing can be 1000 meters, and the grade safety distance for the train to complete the control grade conversion can be 400 meters. The specific grade safety distance can be automatically generated according to the train running environment, or manually set by technicians according to experience. This embodiment does not make specific limitations.

[0072] Exemplarily, the neutral section passing notice information can be sent to the train when the train passes transponder 1; the control grade conversion notice information can also be sent to the train when the train passes transponder 2; and the forced control grade conversion command information can be sent to the train when the train passes transponder 3. It can realize the operation of automatic neutral section passing control during the process of the train performing the control grade conversion.

[0073] In an optional solution of this embodiment, it can be combined with one or more optional solutions in this embodiment. Optionally, the determination method of the grade safety distance is as follows: Determine the grade safety distance for the train to complete the control grade conversion according to the train running route information fed back by the ground transponder and the speed information in the current running state of the train.

[0074] Specifically, the train running route information can be the length information of the connection line between stations and the existing slope information, etc. The running state can be the control system grade and the corresponding speed information of the train running in the connection line between stations, etc.

[0075] Furthermore, the grade safety distance for the train to complete the control grade conversion can be calculated and determined according to the running speed on the connection line and the slope information in the train running route.

[0076] Exemplarily, the operating speed of the connecting line can be 80 km / h, the most adverse gradient between stations can be (28‰), and the grade safety distance for the train to complete the control level conversion can be the distance between the approach balise and the grade conversion balise that satisfies the speed reduction distance from 80 km / h to 45 km / h + the running distance for 5 s. Then, the grade safety distance between the approach balise and the grade conversion balise in the downlink line can be calculated to be approximately 1930 m, and the grade safety distance between the approach balise and the grade conversion balise in the uplink line can be calculated to be approximately 1305 m. This embodiment does not make specific limitations.

[0077] In the technical solution of the embodiment of the present invention, when the radio block center monitors that the train has a need for level conversion and at the same time monitors that the distance between the train control level conversion area and the train neutral section passing area is less than the preset safety distance threshold, a warning message including the train level conversion warning information and the train neutral section passing warning information is generated; for the level conversion platform to determine the balises on the train's driving route according to the warning message that includes both the train level conversion warning information and the train neutral section passing warning information, and select the target balises from the ground balises according to the train level conversion warning information and the train neutral section passing warning information, and send the balise identification of the target balises to the radio block center; and based on the train level conversion warning information and the train neutral section passing warning information, perform balise configuration operations on the target balises to control the target balises to perform level conversion warning and neutral section passing warning. When the distance between the area where the radio block center monitors the train to perform level conversion and the area where the train passes through the neutral section does not meet the preset safety distance threshold, the warning message is sent to the level conversion platform through wireless communication technology, so that the level conversion platform can realize the automatic control of the train's level conversion and neutral section passing according to the warning message, improving the intelligent control of the train and the safety during the driving process.

[0078] Embodiment III

[0079] Figure 3 It is a schematic structural diagram of an inter-level conversion device based on wireless warning of neutral section position provided by an embodiment of the present invention. An inter-level conversion device based on wireless warning of neutral section position provided by an embodiment of the present invention can be applicable to the situation where the train performs inter-level conversion and passes through the neutral section at the same time. The inter-level conversion device based on wireless warning of neutral section position can be implemented in the form of hardware and / or software. The inter-level conversion device based on wireless warning of neutral section position can be configured on the level conversion platform, such as Figure 3 shown, specifically including: a warning message acquisition module 310, a ground balise determination module 320, and a target balise determination module 330. Among them,

[0080] A pre-warning information acquisition module 310 is configured to acquire pre-warning information sent by a radio block center, parse the pre-warning information, and obtain a pre-warning parsing result;

[0081] A ground transponder determination module 320 is configured to determine ground transponders on the train's driving route if the pre-warning parsing result simultaneously includes train grade conversion pre-warning information and train neutral section passing pre-warning information; the train grade conversion pre-warning information and the train neutral section passing pre-warning information are generated by the radio block center when it monitors that the distance between the train control grade conversion area and the train neutral section passing area is less than a preset safety distance threshold;
