[0036] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described below in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0037] The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0038] Referring to Figure 1 , Figure 1 Figure 4 is a functional structure diagram of some embodiments of a vehicle state monitoring system according to the present application. As shown in Figure 1 , the vehicle state monitoring system comprises:

[0039] a vehicle-end MQTT (Message Queuing Telemetry Transport) server 101, a vehicle data center 102 and a cloud server 103;

[0040] The vehicle-end MQTT server 101 is configured to receive state data of a plurality of functional components in a vehicle.

[0041] The vehicle data center 102 is connected to the vehicle-end MQTT server 101 and the cloud server 103, and is configured to process the state data of the plurality of functional components and send the processed state data to the cloud server 103.

[0042] The cloud server 103 is configured to store and analyze the processed state data, and generate vehicle state monitoring information and / or control instructions based on the analyzed data.

[0043] In the embodiments of the present application, the vehicle state information includes but is not limited to vehicle running time, vehicle running state and traffic usage, etc. With these data stored in the cloud server, the fleet manager can also analyze the usage of the vehicle very conveniently.

[0044] In the embodiment of the present application, the vehicle state monitoring system adopts the SOA (Service-Oriented Architecture) architecture design. Different services of the application system can provide services to other services through the communication protocol on the network, and the services in the application system are in a loose coupling relationship. The VDC (Vehicle Data Center) is used as a service in the SOA to receive and process the data of other components and send to the cloud.

[0045] The communication protocol adopted in the embodiment of the present application is MQTT, which is a "lightweight" communication protocol based on the publish / subscribe mode. It provides real-time and reliable message service for connecting remote devices with very little code and limited bandwidth, and is built on the TCP / IP protocol. The MQTT protocol requires client and server communication, and there are three identities in the MQTT protocol: publisher, broker (server), and subscriber. Among them, the message publisher and subscriber are clients, the message broker is a server, and the message publisher can be a subscriber at the same time.

[0046] In the embodiment of the present application, the VDC, the in-vehicle components, and the cloud are all clients of the MQTT protocol. The VDC and the in-vehicle components realize the communication function by publishing and subscribing data to the MQTT server of the vehicle end, the VDC and the cloud realize the communication function by publishing and subscribing data to the MQTT service of the cloud, and the in-vehicle components and the cloud realize the interaction through the VDC service. The VDC service does not need to care about the data content, only pays attention to the data source; the in-vehicle components and the cloud do not need to care about the data source, only care about the data content, and parse the data according to the protocol, thereby improving the monitoring data processing efficiency.

[0047] In the traditional vehicle state monitoring system, the communication between each component and the communication between each component and the cloud leads to the interaction between the in-vehicle components and the cloud in a mesh shape, which brings difficulty to vehicle management; and since each component sends state data to the cloud separately, the cloud processes the state data of multiple in-vehicle components of multiple vehicles, the monitoring data processing efficiency is low, the cloud load is heavy, and the communication network requirement is high.

[0048] The vehicle state monitoring system provided by the embodiment of the application comprises a vehicle end MQTT server, a vehicle data center and a cloud server; the vehicle end MQTT server is configured to receive state data of a plurality of functional components in a vehicle; the vehicle data center is connected with the vehicle end MQTT server and the cloud server respectively, and is configured to process the state data of the plurality of functional components and send the processed state data to the cloud server; and the cloud server is configured to store and analyze the processed state data, and generate vehicle state monitoring information and / or control instructions according to the analyzed data. The vehicle data center builds a bridge for each component in the vehicle and the cloud, and each component in the vehicle and the cloud only need to interact with the vehicle data center, thereby realizing decoupling between the components in the vehicle and between the components in the vehicle and the cloud. The vehicle data center processes the state data of the plurality of components, thereby reducing the load of the cloud and improving the monitoring data processing efficiency.

[0049] Based on any of the above embodiments, as shown in Figure 2 The vehicle data center 102 comprises:

[0050] A message subscription module 201 configured to send a subscription message to the vehicle end MQTT server, wherein the subscription message comprises information for subscribing to the state data of the plurality of functional components;

[0051] A data collection module 202 configured to collect the state data of the plurality of functional components from the vehicle end MQTT server;

[0052] A data processing module 203 configured to process the state data of the plurality of functional components;

[0053] A message publishing module 204 configured to publish the processed state data in the data processing module to the cloud server.

[0054] In some embodiments of the application, processing the state data of the plurality of functional components comprises but is not limited to:

[0055] Adding an identification code to the state data of the plurality of functional components, adding a time stamp to the state data of the plurality of functional components, and packing the state data of the plurality of functional components.

[0056] For example, in a conventional monitoring data collection method, the cloud server needs to identify the vehicle, and the data sent by the components in the vehicle to the cloud server needs to have a vehicle identification code. If the components in the vehicle directly send data, the components in the vehicle need to first obtain the identification code, add it to the data packet and then send it out. In the vehicle state data acquisition method based on the embodiment, the components in the vehicle only need to send out data, and the VDC service receives the data, adds a vehicle identification code and then sends the data to the cloud server.

[0057] For example, some state data is time-series, and the cloud server needs to analyze the time trend of the data. In this case, the VDC service can add a timestamp to the received data and then send it to the cloud server.

[0058] In addition, the VDC service can also package data of different components and send them to the cloud to reduce the concurrency of the cloud MQTT server and the cloud server receiving data, and reduce the pressure on the cloud server. For the cloud server, there can be thousands of vehicles sending data at the same time, and if different components in each vehicle also send data at the same time, the concurrency of the cloud server will be large, for example, 10000 vehicles, each vehicle has 5 components sending data, the concurrency is 50000. The VDC service can package the data of each component in the vehicle and send it together, so the concurrency can be reduced from 50000 to 10000, and the pressure on the cloud server can be reduced to one fifth of the original concurrency.

[0059] It should be noted that the embodiments of the present application only give a few simple examples to illustrate the function of the VDC service in data processing, and the processing function of the VDC service is not limited to the processing mode of the embodiments of the present application. Those skilled in the art can add processing functions according to actual needs.

[0060] In the embodiments of the present application, the VDC and the in-vehicle components realize data interaction by publishing and subscribing data to the vehicle-side MQTT server. The VDC receives and processes data published by other components to the vehicle-side MQTT server, and the in-vehicle components only need to focus on the data of the VDC, without needing to focus on the data of other components, thereby realizing decoupling between the in-vehicle components.

[0061] Based on any of the above embodiments, the vehicle state monitoring system further comprises a cloud MQTT server, the cloud MQTT server is configured to forward the processed state data received from the vehicle data center to one or more cloud servers.

[0062] Each cloud server is further configured to subscribe to and receive the processed data of the vehicle data center from the cloud MQTT server.

[0063] The vehicle data center is further configured to receive the control instructions sent by the cloud MQTT server and forward the control instructions to the plurality of functional components in the vehicle.

[0064] In the traditional architecture, the cloud server sends all control instructions to each in-vehicle component, which parses and obtains its corresponding control instruction. In the embodiment of the present application, the vehicle data center subscribes and receives the control instruction from the cloud server, and the data processing module classifies the control instruction according to each component. Then, the control instruction corresponding to each component is distributed to the corresponding functional component, so that each functional component in the vehicle only needs to focus on and receive the control instruction related to itself from the vehicle data center, thereby reducing network load.

[0065] Figure 3 is a flowchart of the vehicle state monitoring method provided by the present application. As shown in Figure 3 , the vehicle state monitoring method is applied to the vehicle state monitoring system as described in any of the above, comprising:

[0066] Step 301: receiving the state data of a plurality of functional components in the vehicle through the vehicle-end MQTT server;

[0068] Step 303: storing and parsing the processed state data through the cloud server, and generating vehicle state monitoring information and / or control instructions according to the parsed data.

[0072] (3) Based on the connection line 3 between the vehicle-end MQTT server and the data collection module, the VDC service receives data from the vehicle-end MQTT server;

[0073] (4) Based on the connection line 4 between the message subscription module and the data processing module, the VDC service uniformly processes the received data;

[0074] (5) Based on the message publishing module and the cloud-end MQTT server 5, the VDC service publishes the processed data to the cloud-end MQTT server;

[0075] (6) Based on the cloud MQTT server and the cloud (server) connection line 6, each cloud MQTT server subscribes and receives data from the MQTT server, parses the data according to the requirements, and saves it.

[0076] The vehicle state monitoring method provided by the embodiment of the application realizes the interaction decoupling of the components in the vehicle and the cloud, the components in the vehicle and the cloud realize data interaction through the VDC service, the components in the vehicle and the cloud are decoupled, if the components in the vehicle need to send data to the cloud, the data can be published to the vehicle MQTT server to realize it, and the VDC service subscribes to the data and processes and publishes it to the cloud; if the cloud needs to send data to the vehicle, the cloud can publish the data to the cloud MQTT server to realize it, and the VDC service subscribes to the data and processes and publishes it to the vehicle; the interaction of the components in the vehicle is also completed through the interaction between the VDC service.
