Description

Technical Field

[0002] With the continuous increase in train speeds and traffic density along railway lines, not only has rapid socio-economic development been driven, but higher demands have also been placed on the monitoring of the railway's operational environment. Therefore, it is necessary to construct geological disaster monitoring systems, fence (boundary) intrusion alarm systems, clearance intrusion alarm systems, and a high-speed train operation environment safety monitoring platform. These systems will comprehensively integrate various disaster monitoring and alarm information, thereby establishing a unified command, scientific monitoring, and coordinated monitoring and operation mechanism to improve the level of railway traffic safety protection. After constructing the monitoring and operation mechanism, alarm information needs to be accurately sent to the relevant trains.

[0003] Existing vehicle-to-infrastructure (V2I) alarm systems involve building a ground-based base station network and installing a dedicated receiving terminal on the train. Upon triggering a line alarm, the system receives data from a communication management server via a transmission system, forwards the data to various base stations via fiber optic cables, and simultaneously converts the data into wireless signals for transmission to the onboard terminal via an antenna feeder system. This approach requires building a ground-based base station network and installing a dedicated onboard terminal, resulting in high construction costs and raising concerns about the legality of wireless frequencies, thus lacking practical value for widespread adoption.

[0050] Figure 1 This is a flowchart illustrating the vehicle-road cooperative alarm method provided by the present invention, as follows: Figure 1 As shown, the present invention provides a vehicle-road cooperative alarm method, including:

[0051] S110, obtain the train number verification information uploaded by the train and the train operation status information uploaded by the vehicle-road cooperative alarm ground equipment, wherein the train operation status information is determined based on the train approach warning information broadcast by the train to the vehicle-road cooperative alarm ground equipment, and the vehicle-road cooperative alarm ground equipment is located on both sides of the train's operating line;

[0052] S120, Based on the train number verification information and the train operation status information, determine the train location information;

[0053] S130, based on the train location information, determine the target train and the target vehicle-road cooperative alarm ground equipment within a preset range, wherein the preset range is determined based on the alarm information received in advance;

[0054] S140, based on the GSM-R dedicated communication network and the driving safety early warning radio corresponding to the target vehicle-road cooperative alarm ground equipment, an alarm message is sent to the target train.

[0055] GSM-R (Global System for Mobile Communications – Railway) is an international wireless communication standard for railway communications and applications.

[0056] Specifically, the vehicle-road cooperative alarm method described in this invention is implemented based on a vehicle-road cooperative alarm platform.

[0057] The vehicle-road cooperative alarm platform obtains the train number verification information sent by the locomotive integrated wireless system equipment, and extracts information such as the train's locomotive number, train number, speed, operating section, kilometer marker, latitude and longitude. The vehicle-road cooperative alarm ground equipment receives the train approach warning information broadcast by the train, and extracts information such as the train number, locomotive number, kilometer marker, latitude and longitude, and operating speed from the train approach warning information to obtain the train operation status information. The train operation status information is then sent to the vehicle-road cooperative alarm platform, which verifies the train number verification information and the train operation status information to ensure that accurate train location information is obtained.

[0058] The vehicle-road cooperative alarm platform determines the location of an emergency based on alarm information pre-obtained from the train operation environment monitoring platform. It then defines a preset range based on the emergency location and sends alarm information to target trains within that range, facilitating train drivers' decisions on appropriate response measures. When multiple emergencies occur simultaneously, priority is given to alerting trains closest to the nearest train, achieving coordinated alarm functionality between the ground and the vehicle.

[0059] It is understandable that this invention utilizes the existing railway technology and equipment system to obtain train operation location information from two different information channels: train approach warning information and train number verification information. At the same time, the alarm information is uploaded to the operating train through two channels: the train safety warning radio of the target vehicle-road cooperative alarm ground equipment and the GSM-R dedicated communication network. This improves system reliability, eliminates the need to install new receiving terminals on the train, and greatly reduces the construction cost of the vehicle-road cooperative alarm system.

[0060] Based on the above embodiments, as an optional embodiment, the step of sending alarm information to the target train via the GSM-R dedicated communication network and the corresponding train safety warning radio of the target vehicle-road cooperative alarm ground equipment includes:

[0061] Based on the GSM-R dedicated communication network, the alarm information is sent to the network unit of the locomotive integrated wireless communication equipment of the target train and the target vehicle-road cooperative alarm ground equipment. The target vehicle-road cooperative alarm ground equipment is controlled to broadcast the alarm information to the target train through the traffic safety early warning radio, so that the target train can use voice prompts to provide the alarm information, including the time of the emergency alarm, the type of emergency, the location of the emergency, the kilometer marker of the emergency location, the current position of the train, and the distance between the train and the emergency, and display the received alarm event image.

[0062] This invention, while enabling high-speed train operation, provides time for the train to handle emergencies. Alarm information (such as clearance intrusion information) within a predetermined distance (e.g., 20 kilometers) is transmitted to the train cab via a wireless vehicle-to-ground communication channel (including a dedicated GSM-R communication network and a train safety warning radio broadcast). Voice prompts provide the alarm time, type, location, kilometer marker at the location of the emergency, the train's current position, and the distance between the train and the emergency. Simultaneously, images or videos are uploaded, allowing the driver to decide on appropriate actions. When multiple clearance intrusions occur simultaneously, priority is given to alerting the closest emergency to the train, achieving a coordinated alarm function between the ground and the vehicle. This invention utilizes the existing GSM-R network and train safety warning system, while adding a vehicle-to-infrastructure (V2I) cooperative alarm system platform and V2I cooperative alarm ground equipment, enabling the transmission of alarm images and information acquired from the ground to the train.

[0063] Figure 2 This is a flowchart illustrating the process of determining a preset range provided by the present invention, as shown below. Figure 2 As shown, based on the above embodiments, as an optional embodiment, the preset range is determined based on pre-received alarm information, including:

[0064] S210, Based on the previously received alarm information, obtain the alarm location;

[0065] S220, with the alarm location as the center, obtain the preset range of the preset shape.

[0066] The vehicle-road cooperative alarm platform is connected to the train operation environment monitoring platform to obtain alarm information in advance. The alarm information includes at least the geographical location of the alarm location and may also include alarm images. The geographical location information can be latitude and longitude information.

[0067] Optionally, the alarm information includes alarm information containing the location of the emergency, including but not limited to the alarm time, the type of emergency, the location of the emergency, the kilometer marker at the location of the emergency, the current position of the train, the distance between the train and the emergency, and an image of the alarm event.

[0068] Optionally, the preset shape of the preset range can be a circle, a polygon, or an irregular shape, and the present invention does not limit it.

[0069] Optionally, based on a preset radius value, a circle is drawn with the alarm location as the center to obtain a preset range. The preset range may also include a range composed of irregularly shaped curves or a range composed of multiple line segments. For example, a circle is drawn with a radius K of the alarm location, where K is typically 20 km.

[0070] It is understood that the present invention provides a technical solution for determining a preset range. By determining the preset range through pre-received alarm information, alarm information is sent to trains and vehicle-road cooperative alarm ground equipment within the preset range, thereby improving the accuracy of alarm information transmission.

[0071] Figure 3 This invention provides Figure 1 A flowchart of step S130 is shown below. Figure 3 As shown, based on the above embodiments, as an optional embodiment, determining the target train within a preset range and the target vehicle-road cooperative alarm ground equipment within a preset range according to the train location information includes:

[0072] S310, Based on the location information of the train, determine the target train within a preset range;

[0073] S320, Based on the pre-stored location information of the vehicle-road cooperative alarm ground equipment, determine the target vehicle-road cooperative alarm ground equipment within a preset range.

[0074] Optionally, the location information of the train can be used to determine whether the train is within a preset range, and the location information of the vehicle-road cooperative alarm ground equipment can be used to determine whether the vehicle-road cooperative alarm ground equipment is within a preset range.

[0075] Optionally, once the preset range is determined, the latitude and longitude dataset and road sign dataset for the preset range are also determined. Whether a train is within the preset range can be determined by judging whether the train's latitude and longitude and road signs are within the preset range's latitude and longitude dataset and road sign dataset. Similarly, whether a vehicle-road cooperative alarm ground device is within the preset range can be determined by judging whether the vehicle-road cooperative alarm ground device's latitude and longitude and road signs are within the preset range's latitude and longitude dataset and road sign dataset.

[0076] It is understood that the present invention provides a technical solution for identifying target trains and target vehicle-road cooperative alarm ground equipment, which can accurately identify the required target trains and target vehicle-road cooperative alarm ground equipment, and improve the accuracy of alarm information push.

[0077] Based on the above embodiments, as an optional embodiment, the vehicle-road cooperative alarm method provided by the present invention further includes:

[0078] Based on pre-stored train line information, train interference lines within a preset range are obtained. When sending the alarm information, trains on the train interference lines and vehicle-road cooperative alarm ground devices on both sides of the train interference lines are filtered out.

[0079] Specifically, the vehicle-road cooperative alarm platform has a line operation database, which pre-stores line information for the corresponding jurisdiction area. If there are other lines within a circular area with a radius of K at the alarm location, the vehicle-road cooperative alarm ground equipment located on the interfering line and on both sides of the interfering line will be filtered out when the alarm information is pushed.

[0080] Optionally, the method for determining the interfering line includes searching for other pre-stored line location points within a preset range, in addition to the target line, based on pre-stored train line information. The lines where these location points are located are the interfering lines.

[0081] Optionally, the train filtering method is as follows: trains that are more than 200 meters away from the target line and whose distance from the interfering line is less than the distance between the train and the target line are filtered out.

[0082] Optionally, the method for filtering vehicle-road cooperative alarm ground equipment includes: deploying vehicle-road cooperative alarm ground equipment on other lines (i.e. non-target lines) outside the target line; vehicle-road cooperative alarm ground equipment that meets this condition is filtered out, and only vehicle-road cooperative alarm ground equipment deployed along the target line is retained.

[0083] It is understood that by identifying the train interference line, this invention avoids sending alarm information to the train and the ground equipment for vehicle-road cooperative alarms corresponding to the train interference line, thereby further improving the accuracy of alarm information transmission.

[0084] Based on the above embodiments, as an optional embodiment, the vehicle-road cooperative alarm method provided by the present invention further includes:

[0085] Based on the train number verification information, the train operation trend is determined, and when sending the alarm information, trains whose operation trend is far away from the preset range are filtered out.

[0086] Optionally, the latitude and longitude information of the train can be extracted from the multiple train number verification information and compared with the alarm location in turn to determine the distance difference between the train and the alarm location. If the difference becomes larger and larger, it is considered that the train is moving away from the preset range (i.e., the alarm range). If the difference becomes smaller and smaller, it is considered that the train is moving closer to the preset range (i.e., the alarm range).

[0087] It is understood that by filtering out trains that are far from the preset range, the present invention can identify more precise alarm targets and further improve the accuracy of alarm information transmission.

[0088] The vehicle-road cooperative alarm system provided by the present invention is described below. The vehicle-road cooperative alarm system described below can be referred to in correspondence with the vehicle-road cooperative alarm method described above.

[0089] Figure 4 This is one of the principle block diagrams of the vehicle-road cooperative alarm system provided by the present invention, such as... Figure 4 As shown, the present invention also provides a vehicle-road cooperative alarm system, including a vehicle-road cooperative alarm platform 410 and a vehicle-road cooperative alarm ground device 420, wherein the vehicle-road cooperative alarm ground device 420 is installed on both sides of the train's running line;

[0090] The vehicle-road cooperative alarm ground device 420 is used to acquire the train approach warning information broadcast by the train, determine the train operation status information based on the train approach warning information, and upload the train operation status information to the vehicle-road cooperative alarm platform 410.

[0091] The vehicle-road cooperative alarm platform 410 is used to acquire the train operation status information and the train number verification information uploaded by the train; determine the train location information based on the train number verification information and the train operation status information; determine the target train and the target vehicle-road cooperative alarm ground equipment within a preset range according to the train location information; and send alarm information to the target train based on the GSM-R dedicated communication network and the traffic safety warning radio corresponding to the target vehicle-road cooperative alarm ground equipment. The alarm information sent through the GSM-R dedicated communication network also includes an alarm event image. The preset range is determined based on the alarm information received in advance.

[0092] Figure 5 This is the second principle block diagram of the vehicle-road cooperative alarm system provided by the present invention. Figure 6 This is a schematic diagram of the information processing flow of the vehicle-road cooperative alarm system provided by the present invention, such as... Figure 5 and Figure 6As shown, specifically, the train is equipped with a train operation monitoring device and a locomotive integrated wireless communication device, both of which are existing equipment in the current railway equipment system. The locomotive integrated wireless communication device connects to the train operation safety monitoring device via a TAX box to obtain location information such as the train's operating section and kilometer markers, as well as status information such as the locomotive number, train number, and speed. During train operation, the locomotive integrated wireless communication device broadcasts an approach warning every 200 meters via the LBJ (Train Protection Alarm) device radio, and every 30 seconds sends a train number verification message to the M-GRIS via the GSM-R railway dedicated communication network. The M-GRIS then forwards the received train number verification message to the vehicle-road cooperative alarm platform.

[0093] The TAX box provides information for the wireless train number verification system, periodically transmitting train number information to the locomotive data acquisition encoder via an RS-485 interface. The M-GRIS equipment is existing equipment in the railway system.

[0094] The vehicle-road cooperative alarm ground equipment is installed on both sides of the train's operating line. It receives train approach warning information broadcast by the locomotive integrated wireless system via the LBJ device radio, extracts information such as the locomotive number, train number, speed, operating section, kilometer marker, and latitude and longitude, and uploads this information to the vehicle-road cooperative alarm platform via the railway intranet. When the vehicle-road cooperative alarm platform receives intrusion warning information (including location) sent by the train operation environment monitoring platform, it performs intelligent calculations based on the locomotive location information reported by the ground-installed vehicle-road cooperative alarm equipment, identifies the train approaching the warning location, and sends the warning information and images to the onboard locomotive integrated wireless communication equipment via the GSM-R network. The warning information is then transmitted via the railway intranet to multiple vehicle-road cooperative alarm ground devices centered on the warning location, triggering the ground devices to broadcast line fault alarm information via radio. The locomotive integrated wireless communication equipment receives the warning information and images sent by the vehicle-road cooperative alarm platform and issues an audible and visual alarm.

[0095] It is understood that this invention obtains train operating position information through two different information channels: train approach warning information and train number verification information. At the same time, it sends the alarm information to the target train through two channels: the train safety warning radio of the target vehicle-road cooperative alarm ground equipment and the GSM-R dedicated communication network. This improves system reliability, eliminates the need to install new receiving terminals on the train, and greatly reduces the construction cost of the vehicle-road cooperative alarm system.

[0096] Based on the above embodiments, as an optional embodiment, the present invention provides a vehicle-road cooperative alarm system, which further includes a locomotive integrated wireless communication device installed on the train;

[0097] The locomotive integrated wireless communication equipment is used to acquire the alarm information sent by the vehicle-road cooperative alarm platform via the GSM-R dedicated communication network, so that the train can broadcast the alarm information.

[0098] After receiving alarm information and alarm images sent through the GSM-R railway private network, the train's integrated wireless communication equipment displays the alarm images and alarm information to the train driver, and simultaneously reports the alarm information to the driver via voice broadcast.

[0099] Based on the above embodiments, as an optional embodiment, according to the vehicle-road cooperative alarm system provided by the present invention, the vehicle-road cooperative alarm ground equipment is further used to convert the alarm information into line obstacle alarm information in a preset format and broadcast the line obstacle alarm information;

[0100] The locomotive integrated wireless communication equipment is also used to acquire the line fault alarm information so that the train can broadcast the line fault alarm information.

[0101] Optionally, when the vehicle-road cooperative alarm ground equipment receives alarm information pushed by the vehicle-road cooperative alarm platform, it sends line obstacle alarm information that conforms to the railway protocol to the train.

[0102] The LBJ device of the locomotive integrated wireless communication equipment can receive line fault alarm information sent by the vehicle-road cooperative alarm ground equipment, display the received information to the driver, and report the alarm information to the driver through voice broadcast.

[0103] Figure 7 This is a schematic diagram of the software module framework of the vehicle-road system alarm platform provided by the present invention, as shown below. Figure 7 As shown, based on the above embodiments, as an optional embodiment, the vehicle-road cooperative alarm platform includes a management service module, a sending service module, an analysis service module, and an access gateway service module;

[0104] The management service module is used to manage the sending service module, the analysis service module, and the access gateway service module, and is also used to perform database operation processing.

[0105] The analysis service module is used to perform analysis and processing on the vehicle-road cooperative alarm platform.

[0106] The sending service module is used to push the alarm information;

[0107] The access gateway service module is used to enable the train, the vehicle-road cooperative alarm ground equipment, and the train operation environment monitoring platform to access the system. The train operation environment monitoring platform is used to send the alarm information to the vehicle-road cooperative alarm platform.

[0108] Optionally, the management service module is a backend service module that centrally manages other modules and performs database operations; the analysis service module is a backend service module that performs intelligent analysis to identify approaching trains with clearance alarms and to identify vehicle-road cooperative alarm ground equipment with associated clearance alarms; the sending service module is a backend service module that pushes alarm information to trains and to vehicle-road cooperative alarm ground equipment; the access gateway service module is a backend service module that enables access to vehicle-road cooperative equipment and external systems such as train operation environment monitoring platforms; and the storage service module is used to store data information.

[0109] The vehicle-road cooperative alarm platform is the core of the vehicle-road cooperative alarm system. It can be installed in the core computer room to interface with the operational safety environment monitoring platform and accurately identify the targets for early warning. The vehicle-road cooperative alarm platform system adopts a distributed modular design, mainly including client, management service module, sending service module, analysis service module, access gateway service module, and storage service module. Each business module has a clear responsibility, and the modules are loosely coupled, which can flexibly adapt to changes in functional requirements and technology, and has strong compatibility, scalability, and portability.

[0110] The following is an example of the vehicle-road system alarm system provided by the present invention.

[0111] The vehicle-road cooperative alarm system mainly consists of locomotive integrated wireless communication equipment, vehicle-road cooperative alarm platform, and vehicle-road cooperative alarm ground equipment.

[0112] The system installs vehicle-road cooperative alarm ground equipment in the pilot section to acquire train approach warning information broadcast by the locomotive from the train operation safety early warning system in real time, and uploads it to the vehicle-road cooperative alarm platform via the railway intranet. When the vehicle-road cooperative alarm platform receives intrusion clearance alarm information including location from the train operation environment monitoring platform, it performs intelligent calculations based on the train approach warning information reported by the vehicle-road cooperative alarm ground equipment, identifies the train approaching the clearance alarm, and sends the alarm image and data to the onboard CIR equipment via the GSM-R network. It also sends the alarm information to the relevant vehicle-road cooperative alarm ground equipment via the railway intranet, triggering the vehicle-road cooperative alarm ground equipment to broadcast line fault alarm information via radio. The onboard CIR equipment of the test train registers with the vehicle-road cooperative alarm platform and is capable of receiving alarm videos, images, and data sent by the platform, and issuing audible and visual alarm prompts.

[0113] This system, operating at high speeds, transmits information about clearance incursions within 20 kilometers of the train to the driver's cab via wireless vehicle-to-ground communication to gain time for handling emergencies. Voice prompts provide the alarm time, type, location, kilometer marker at the location of the incursion, the train's current position, and the distance between the train and the incursion. Simultaneously, images or videos are uploaded, allowing the driver to decide on appropriate actions. When multiple clearance incursions occur simultaneously, priority is given to the incursion closest to the train, enabling coordinated ground and vehicle alarm functionality. The system utilizes the existing GSM-R network and train safety early warning system, while also incorporating a vehicle-to-infrastructure (V2I) cooperative alarm platform and V2I cooperative alarm ground equipment to transmit alarm images and information acquired from the ground to the train.

[0114] Among them, the locomotive integrated wireless communication equipment, abbreviated as CIR, is a railway-specific communication equipment. As an upgraded product of the traditional wireless train dispatching radio, CIR equipment is an essential device to ensure train operation safety and is a comprehensive platform for realizing train-rail data and voice transmission.

[0115] All existing functions of the CIR equipment are retained, with the addition of a vehicle-to-infrastructure (V2I) cooperative alarm program. This primarily involves registering with the V2I cooperative alarm platform, receiving alarm videos, images, and data from the platform, and issuing audible and visual alarm prompts. The existing business procedures and the vehicle-to-ground alarm program run in parallel to ensure that existing services are not affected.

Acquiring all online locomotive heartbeat information data from registered CIR equipment via the GSM-R wireless network, including locomotive attributes and location information. And acquiring clearance alarm data through an interface with the train operation environment monitoring platform. The system includes information and images; intelligent screening of locomotives near the acquired alarm locations; filtering out locomotives within the alarm range (configurable distance, currently 20km); pushing alarm images and information to onboard equipment via the GSM-R network; sending alarm information to the nearest vehicle-to-infrastructure (V2I) ground alarm device via the GSM-R intranet; notifying the V2I ground alarm device to broadcast alarm information via radio; managing and pushing alarm information to V2I ground alarm devices; supporting CIR device registration and alarm information push functions. It features dual-redundancy alarm protection, supporting alarm information uploads to the train via both the GSM-R channel and the V2I ground alarm device. Monitoring data is retained for at least 12 months, device status information for at least 12 months, and alarm data for at least 24 months.

[0117] Optionally, the interface between the vehicle-road cooperative alarm platform and the train operation environment safety monitoring platform uses the MQTT protocol for connection. The MQTT connection requires TLS mutual authentication. Authorization is performed using username + password + clientId + topic: each manufacturer or MQTT client (collectively referred to as the client) is assigned a unique username + password + clientId + topic by the platform during integration. Each client's topic is unique. The MQTT message protocol requires packet transmission, with each packet not exceeding 64KB.

[0118] Optionally, the interface message topics of the vehicle-road cooperative alarm platform include: receiving alarm information and alarm images; reporting ground registration information / device status for vehicle-to-ground cooperative alarms; reporting registration information / status of onboard CIR devices; reporting alarm information from onboard CIR devices; reporting alarm information from vehicle-to-ground cooperative alarm devices; and synchronizing the status of vehicle-to-ground cooperative alarm devices and onboard CIR devices.

[0119] Optionally, the core algorithm of the vehicle-road cooperative alarm platform includes: after acquiring the alarm location and online train and location information, the vehicle-road cooperative alarm platform uses the GEOHASH algorithm to filter out online trains within a certain radius of the alarm area and obtains the distance information between the alarm area and the online trains. Further, an alarm protection and early warning model is constructed, and driving early warning and protection reminder information is determined based on the approach / departure trends of online trains and the alarm area, and electronic map constraints.
