[0002] A large number of monitoring devices and sensors are often deployed in current trains. Due to the functional differences between monitoring devices and sensors, the data they transmit has different requirements in terms of transmission rate and real-time performance. For example, some devices may need to transmit high-frequency monitoring data in real time to ensure the accuracy and timeliness of monitoring; while other devices may only need to transmit relatively low-frequency data periodically. This diversity of data transmission requirements places higher requirements on transmission bandwidth and real-time performance.

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Figure 1 It is one of the flow charts of the method for constructing the train intelligent monitoring network provided by the present invention.

[0030] The following will be combined Figure 1 The process of the method for constructing the train intelligent monitoring network provided by the present invention is explained.

[0031] In an exemplary embodiment of the present invention, Figure 1 It can be seen that the method for constructing a train intelligent monitoring network may include steps 110 to 140, and each step will be introduced below.

[0032] In step 110, each monitoring device and each monitoring requirement at each preset collection point in the train compartment are determined.

[0033] In step 120, according to the monitoring requirements, a plurality of communication protocols matching the respective monitoring requirements and applicable to the monitoring device are determined.

[0034] In one embodiment, each monitoring device and each monitoring requirement at each preset collection point in the train compartment can be determined. Among them, the preset collection point can be adjusted according to the actual situation, which will not be repeated in this embodiment. In one example, the preset collection point can be a collection point for collecting vibration data of the running gear. In this scenario, it is necessary to identify the monitoring equipment for collecting vibration data of the running gear and the corresponding monitoring requirements. It can be understood that for the monitoring equipment for collecting vibration data of the running gear, its monitoring requirement is high-bandwidth, extremely low-latency monitoring data transmission. In another example, the preset collection point can be a collection point for collecting video data. In this scenario, it is necessary to identify the monitoring equipment for collecting video data and the corresponding monitoring requirements. It can be understood that for the monitoring equipment for collecting video data, its monitoring requirement is high-bandwidth, low-latency monitoring data transmission.

[0035] Furthermore, multiple communication protocols that match the respective monitoring requirements and can be applied to the monitoring equipment can be determined according to the corresponding monitoring requirements. Continuing with the above-mentioned embodiment as an example, for the scenario of collecting vibration data of the running gear, it is necessary to use the Ethernet protocol to achieve high-bandwidth, extremely low-latency monitoring data transmission; for the scenario of collecting video data, it is necessary to use the Matter over WiFi protocol and WiFi-Mesh technology to achieve high-bandwidth, extremely low-latency monitoring data transmission.

[0036] In step 130, multiple communication protocols are added to the Matter network structure to obtain a Matter network structure including multiple communication protocols.

[0037] In step 140, based on the Internet protocol, a vehicle-level local area network is constructed by applying a Matter network structure that includes multiple communication protocols.

[0038] In another embodiment, multiple communication protocols can be integrated into the Matter network structure to obtain a Matter network structure that includes multiple communication protocols. Furthermore, based on Internet protocols, such as IPv6 protocols, a Matter network structure that includes multiple communication protocols can be constructed to achieve ubiquitous massive connections, multiple protocols, high reliability, high security, and integrated vehicle-level local area network.

[0039] The method for constructing a train intelligent monitoring network provided by the present invention determines each monitoring device and each monitoring requirement at each preset collection point in a train car; according to the monitoring requirements, determines multiple communication protocols that match each monitoring requirement and can be applied to the monitoring device; adds multiple communication protocols to the Matter network structure to obtain a Matter network structure containing multiple communication protocols; based on the Internet protocol, applies the Matter network structure containing multiple communication protocols to construct a car-level local area network. Since the constructed car-level local area network applies the Matter network structure containing multiple communication protocols, it can be achieved under the car-level local area network that the monitoring data under different communication protocols can be connected and coordinated.

[0040] Figure 2 It is a flow chart of adding multiple communication protocols to a Matter network structure to obtain a Matter network structure including multiple communication protocols, as provided by the present invention.

[0041] The following will be combined Figure 2 The process of adding multiple communication protocols to a Matter network structure to obtain a Matter network structure including multiple communication protocols is described.

[0042] In an exemplary embodiment of the present invention, Figure 2 It can be seen that adding multiple communication protocols to the Matter network structure to obtain a Matter network structure including multiple communication protocols may include steps 210 to 240, and each step will be introduced below.

[0043] In step 210, when the monitoring requirement is a first monitoring requirement, an Ethernet communication protocol that matches the first monitoring requirement and can be applied to the monitoring device is determined according to the first monitoring requirement.

[0044] In one embodiment, when the monitoring requirement is the first monitoring requirement, since the first monitoring requirement can be used to characterize the monitoring requirement that requires high bandwidth and extremely low latency transmission when performing monitoring data transmission, then, based on the first monitoring requirement, an Ethernet communication protocol that matches the first monitoring requirement and can be applied to the monitoring device can be determined. It can be understood that the monitoring equipment that matches the first monitoring requirement can perform monitoring data transmission based on the Ethernet communication protocol in the car-level local area network, thereby ensuring high bandwidth and extremely low latency transmission during data transmission. Among them, the bandwidth of the high bandwidth is greater than the preset bandwidth; the delay of the extremely low delay is less than the first preset delay. The preset bandwidth and the first preset delay can be adjusted according to actual conditions, and will not be repeated in this embodiment.

[0045] In step 220, when the monitoring requirement is the second monitoring requirement, a WiFi communication protocol that matches the second monitoring requirement and can be applied to the monitoring device is determined according to the second monitoring requirement.

[0046] In one embodiment, when the monitoring requirement is the second monitoring requirement, since the second monitoring requirement can be used to characterize the monitoring requirement that requires high bandwidth and low latency transmission when performing monitoring data transmission, then, according to the second monitoring requirement, a WiFi communication protocol that matches the second monitoring requirement and can be applied to the monitoring device can be determined. It can be understood that the monitoring device that matches the second monitoring requirement can perform monitoring data transmission based on the WiFi communication protocol in the vehicle-level local area network, thereby ensuring high bandwidth and low latency transmission during the data transmission process. Among them, the delay of the low latency is less than the second preset delay and greater than the first preset delay.

[0047] In step 230, when the monitoring requirement is the third monitoring requirement, a Thread communication protocol that matches the third monitoring requirement and can be applied to the monitoring device is determined according to the third monitoring requirement.

[0048] In one embodiment, when the monitoring requirement is the third monitoring requirement, since the third monitoring requirement can be used to characterize the monitoring requirement that requires low bandwidth and low latency transmission when performing monitoring data transmission, then, according to the third monitoring requirement, a Thread communication protocol that matches the third monitoring requirement and can be applied to the monitoring device can be determined. It can be understood that the monitoring device that matches the third monitoring requirement can perform monitoring data transmission based on the Thread communication protocol in the vehicle-level local area network, thereby ensuring low bandwidth and low latency transmission during data transmission. Among them, the bandwidth of the low bandwidth is less than the preset bandwidth.

[0049] In step 240, the Ethernet communication protocol, and / or the WiFi communication protocol, and / or the Thread communication protocol are added to the Matter network structure to obtain a Matter network structure including multiple communication protocols.

[0050] In another embodiment, the Ethernet communication protocol, and / or the WiFi communication protocol, and / or the Thread communication protocol can be added to the Matter network structure to obtain a Matter network structure including multiple communication protocols. Then, based on the Internet protocol, such as IPV6, the Matter network structure including multiple communication protocols is applied to construct a car-level local area network. In this embodiment, since the constructed car-level local area network applies the Matter network structure including multiple communication protocols, a car-level local area network that realizes ubiquitous massive connection, multi-protocol, high reliability, high security, and integration can be constructed. Under the car-level local area network, it can ensure the connectivity and coordination between monitoring data under different communication protocols.

[0051] In another exemplary embodiment of the present invention, the above-mentioned embodiment is continued to be used as an example for explanation. Before adding multiple communication protocols to the Matter network structure to obtain the Matter network structure including multiple communication protocols, the method for constructing a train intelligent monitoring network may further include the following steps: When it is determined that a non-Matter protocol monitoring device is deployed in the train carriage, a non-Matter protocol connection communication protocol is obtained, wherein the non-Matter protocol connection communication protocol at least includes a Bluetooth connection communication protocol and a Zigbee connection communication protocol; the non-Matter protocol monitoring device transmits monitoring data based on the non-Matter protocol connection communication protocol in the carriage-level local area network; Furthermore, multiple communication protocols and non-Matter protocol connection communication protocols are added to the Matter network structure to obtain a Matter network structure including multiple communication protocols.

[0052] In one embodiment, when it is determined that the train car is deployed with monitoring equipment under non-Matter protocols, non-Matter protocol connection communication protocols can be obtained, such as Bluetooth connection communication protocols and Zigbee connection communication protocols. Further, multiple communication protocols and non-Matter protocol connection communication protocols are added to the Matter network structure to obtain a Matter network structure containing multiple communication protocols, and based on the Internet protocol, such as IPV6, the Matter network structure containing multiple communication protocols is applied to construct a car-level local area network. In this embodiment, since the constructed car-level local area network applies the Matter network structure containing multiple communication protocols, a car-level local area network that realizes ubiquitous massive connection, multi-protocol, high reliability, high security, and integration can be constructed. Under the car-level local area network, it can ensure the communication and coordination between monitoring data under different communication protocols. In this embodiment, in addition to realizing data intercommunication of monitoring equipment under non-Matter protocols, data intercommunication of monitoring equipment under Matter protocols can also be realized.

[0053] In the aforementioned embodiment, by arranging multiple monitoring devices in each carriage of the train, and then based on the IPv6 protocol and Matter network architecture, using Ethernet, WiFi, Thread, Bluetooth, Zigbee, 5G and other communication technologies, intelligent monitoring and control between monitoring devices can be achieved, and a stable, safe and efficient train intelligent monitoring LAN can be built.

[0054] In another exemplary embodiment of the present invention, the above-mentioned embodiment is continued to be used as an example for description. The method for constructing a train intelligent monitoring network may further include the following steps: Based on Mesh technology, the monitoring devices matching the second monitoring requirement are constructed into a WiFi network mesh topology, and\or Based on Mesh technology, monitoring devices that match the third-party monitoring requirements are constructed into a Thread network mesh topology.

[0055] In one embodiment, a multi-node, decentralized, self-organizing Mesh technology is used to implement a wireless sensor / monitoring network of Wi-Fi and Thread protocols (corresponding to WiFi network mesh topology and network mesh topology). After a single sensor / monitoring node fails, it can intelligently form a new mesh topology, and the network has strong self-healing properties.

[0056] Figure 3 This is the second flow chart of the method for constructing the train intelligent monitoring network provided by the present invention.

[0057] The following will be combined Figure 3 The process of constructing another method for an intelligent train monitoring network is described.

[0058] In an exemplary embodiment of the present invention, Figure 3 It can be seen that the method for constructing a train intelligent monitoring network may further include steps 310 to 360, and each step will be introduced below.

[0059] In step 310 , when the monitoring device is a monitoring device that matches the second monitoring requirement, a WiFi access point is acquired.

[0060] In step 320 , based on the WiFi access point, the monitoring device matching the second monitoring requirement is incorporated into the vehicle compartment-level local area network.

[0061] In one embodiment, the WiFi access point can be used to connect to a WiFi device based on the Matter protocol (corresponding to a monitoring device that matches the second monitoring requirement). During the application process, when the monitoring device is a monitoring device that matches the second monitoring requirement, the WiFi access point can be obtained, and based on the WiFi access point, the monitoring device that matches the second monitoring requirement can be incorporated into the vehicle-level local area network.

[0062] In another embodiment, Matter devices can access the network through WiFi APs and be managed uniformly through Matter controllers to interoperate with devices based on Thread or other protocols. They can also be connected to the car's router via Ethernet to transmit data from wireless devices to the car's wired network. The router is responsible for forwarding traffic from each AP to the data storage device.

[0063] In step 330, when the monitoring device is a monitoring device matching the third monitoring requirement, a Thread border router is acquired.

[0064] In step 340 , based on the Thread border router, the monitoring device matching the third monitoring requirement is incorporated into the vehicle-level local area network.

[0065] In another embodiment, when the monitoring device is a monitoring device that matches the third monitoring requirement, a Thread border router may be obtained. Further, based on the Thread border router, the monitoring device that matches the third monitoring requirement is incorporated into the vehicle-level local area network.

[0066] Since the Thread network itself does not support IP, in Matter over Thread, the Thread border router needs to assign IP addresses to devices in the Thread network, thereby connecting the Thread network (a low-power mesh network) with other IP networks (such as Ethernet, Wi-Fi, etc.). It enables Thread-based devices to communicate with devices in other networks, achieving interconnection of the entire system. One or more Thread border routers can be deployed in the LAN of each car to connect the Thread network in the car with the Ethernet or Wi-Fi network.

[0067] In step 350, when the monitoring device is a non-Matter protocol monitoring device, a Matter bridge connector is obtained.

[0068] In step 360, based on the Matter bridge connector, the non-Matter protocol monitoring device is integrated into the vehicle-level local area network.

[0069] In another embodiment, a Matter bridge connector can be obtained when the monitoring device is a monitoring device under a non-Matter protocol. And based on the Matter bridge connector, the monitoring device under the non-Matter protocol is incorporated into the vehicle-level local area network. During the application process, the Matter bridge connector can allow devices with different communication protocols to access the Matter network and interoperate with Matter devices. Through the Matter bridge, non-Matter devices (such as devices based on Zigbee, Z-Wave, Bluetooth or other protocols) can communicate seamlessly with devices in the Matter network. The Matter bridge connector can be an independent device or integrated in a gateway. During the application process, you can choose a gateway device that supports multiple protocols or a dedicated bridge, such as a Zigbee to Matter bridge, according to your needs.

[0070] In another exemplary embodiment of the present invention, the method for constructing a vehicle intelligent monitoring network may further include the following steps: Based on the Matter protocol, corresponding device IPs are allocated to monitoring devices to manage monitoring devices based on device IPs.

[0071] In one embodiment, each wired / wireless sensor and monitoring device uses an automatically configured IPv6 address for identification and communication when accessing a local area network. IPv6 makes it easier to assign unique addresses to devices, ensuring that each device has an independent address in a large-scale network, facilitating cross-network communication.

[0072] In another embodiment, the Matter protocol has a built-in security authentication mechanism, that is, the constructed car-level local area network also has a security authentication mechanism, and all devices can join the network after passing identity authentication. Communication between devices uses end-to-end encryption to ensure the security of data transmission. During the application process, an access control mechanism is also used to ensure that only authorized devices can access specific resources.

[0073] In another exemplary embodiment of the present invention, the above-mentioned embodiment is continued to be used as an example for description, wherein the management of the monitoring device based on the device IP can be implemented in the following manner: Based on the Matter protocol, a management platform is constructed, wherein the management platform can be accessed by different types of management devices, wherein the management device is used to manage the monitoring device; A single management device is called to access the management platform so that the management device can manage the monitoring device through the device IP based on the management platform.

[0074] It is known from the related art that it is difficult to achieve unified configuration and management of monitoring devices under different communication protocols through a single management device. In this embodiment, a management platform will be constructed based on the Matter application layer protocol, wherein the management platform can be accessed by different types of management devices, wherein the management devices are used to manage monitoring devices. In one example, different types of management devices can be management devices used on mobile terminals or management devices used on non-mobile terminals. During the application process, a single management device can be called to access the management platform, and the management platform can be accessed through the management device to achieve configuration and management of monitoring devices with different communication protocols and different functions based on the management platform through the device IP. Through this embodiment, it is achieved that the configuration and management of the entire vehicle or each monitoring device in a vehicle can be completed through a single management device.

[0076] The following will be combined Figure 4 The process of constructing another method for an intelligent train monitoring network is described.

[0077] In another exemplary embodiment of the present invention, Figure 4 It can be seen that the method for constructing a train intelligent monitoring network may include steps 410 to 460, wherein steps 410 to 440 are respectively Figure 1 Steps 110 to 140 are the same or similar to those in the above description. Please refer to the above description for the specific implementation and beneficial effects thereof. They will not be repeated in this embodiment. Steps 450 and 460 will be introduced respectively below.

[0078] In step 450, a plurality of carriage-level local area networks are constructed for carriages other than the train carriages and for other areas of the train other than the train carriages according to the method for constructing a train intelligent monitoring network.

[0079] In step 460, multiple compartment-level LANs are connected based on Ethernet to obtain a vehicle-level LAN.

[0080] In one embodiment, it can also be other carriages other than train carriages, and other areas in the train other than train carriages. In other words, for any area of ​​the train, multiple carriage-level LANs can be constructed according to the construction method of the train intelligent monitoring network. Further, based on Ethernet, multiple carriage-level LANs are connected to obtain a whole-vehicle-level LAN.

[0081] In another embodiment, other carriages outside the train carriages, and other areas in the train except the train carriages, may include under the train, in the carriages, and outside the train. In the application process, multiple carriage-level LANs may be constructed for under the train, in the carriages, and outside the train, respectively, and then connected via Ethernet through WiFi AP (with routing function) nodes to form a vehicle local area network (LAN), and the vehicle LANs are connected to each other through LAN routers, thereby forming a whole train intelligent monitoring network, that is, a whole vehicle-level LAN.

[0082] In another embodiment, a car-level LAN (which can be regarded as a Matterfabric) is constructed in each car, and the car-level LANs of each car are connected via Ethernet or WiFi through a wired / wireless router to form a complete vehicle-level LAN. Through 5G, it can communicate with the remote management system / ground control center to achieve remote management, real-time monitoring and intelligent linkage of trains and on-board equipment.
