Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In order to solve or at least partially solve the above technical problems, an embodiment of the present invention provides a method for reporting vehicle state data. The method for reporting the vehicle state data is applied to the cloud, wherein the cloud refers to a background server relative to a vehicle and a terminal (particularly a terminal provided with a terminal application program such as a mobile phone application APP). The cloud may include a remote control server (abbreviated as remote) and a shadow server (abbreviated as shadow). The remote control server is used for providing remote control services, namely business processing services, including database inquiry, redis inquiry, vehicle state setting, third party pushing call and the like. The shadow server is used for providing a shadow service, the shadow service is used for feeding back the current state of the vehicle, can be communicated with the vehicle through an MQTT (Message Queuing Telemetry Transport, message queue telemetry transport) communication protocol, and is connected with a remote control server as an intermediate service.
Fig. 1 is a flowchart of a method for reporting vehicle status data according to an embodiment of the present invention. Referring to fig. 1, the reporting method may at least include the following steps S102 to S106.
In step S102, the shadow server receives vehicle status data reported by the vehicle, where the vehicle status data carries a first vehicle identifier.
In step S104, the shadow server determines, according to the first vehicle identifier, a service status priority of the vehicle corresponding to the first vehicle identifier.
In step S106, the shadow server transmits the vehicle status data to the remote control server through the data channel corresponding to the service status priority of the vehicle.
After receiving the vehicle state data, the remote control server can store the vehicle state data into a memory in the remote control server, and can further transmit the vehicle state data to a designated buffer for storage, so that the reported vehicle state data is stored into a cloud.
In the method for reporting vehicle state data provided by the embodiment of the invention, the shadow server determines the service state priority of the vehicle corresponding to the first vehicle identifier according to the received first vehicle identifier carried by the vehicle state data reported by the vehicle, and sends the vehicle state data to the remote control server through the data channel corresponding to the service state priority of the vehicle. According to the scheme, the reported vehicle state data can be classified according to the service state priority of the vehicle reporting the data, so that the data reported by the vehicle with high priority can be processed preferentially, and the problem of delay in vehicle state storage is relieved and even solved.
In the embodiment of the invention, the vehicle state data is data for representing the real-time state of the vehicle, such as the vehicle oil quantity, the vehicle engine temperature, the opening and closing conditions of the doors and windows of the vehicle, and the like. The vehicle identification is used for distinguishing different vehicles and is used for uniquely identifying and determining the vehicles. Specifically, the vehicle identification may be one of the following train vehicle identification information: a car networking device ID, a car identification code (Vehicle Identification Number, VIN), a mobile station international integrated services digital network number (Mobile Subscriber International ISDN number, MSISDN) associated with the car hardware, an international mobile subscriber identity (International Mobile Subscriber Identity, IMSI), an integrated circuit card identity (Integrate circuit card identity, ICCID), an infotainment host identity (Infotainment Head Unit Identity, IHUID), etc.
In the step S102, the vehicle may periodically report the vehicle state data according to a preset frequency (for example, 1 min), or may trigger reporting the vehicle state data when the vehicle state changes (for example, when the opening and closing states of the doors and windows of the vehicle change), or may combine the two modes to report the vehicle state data, and so on. Further, the shadow server receives vehicle state data reported by the vehicle and modifies data in the corresponding mapping module.
In step S104 above, the shadow server determines the service status priority of the corresponding vehicle according to the first vehicle identifier.
In one embodiment, the shadow server may include a plurality of mapping modules, each mapping module corresponding to a vehicle identification and storing a service status priority of a vehicle corresponding to the vehicle identification. In this case, step S104 may be further implemented as: the shadow server firstly determines a first mapping module corresponding to a first vehicle identifier according to the first vehicle identifier carried by the vehicle state data, and then obtains the service state priority corresponding to the first vehicle identifier from the corresponding first mapping module.
The service state priority of the vehicle corresponding to the vehicle identifier stored in the mapping module may be generated according to a use state of the terminal corresponding to the vehicle. The terminal referred to herein may correspond to one or more vehicles, and in particular may be set by an application of the terminal to a plurality of users or to a plurality of vehicles. The terminal may be used to view the state of the corresponding vehicle through a corresponding application on the terminal, for example, the terminal may be a mobile phone, and view the state of the corresponding vehicle through a vehicle state query APP on the mobile phone. The service state priority of the vehicle refers to the processing priority of data sent to the cloud by the vehicle. The higher the priority of the service status priority of a vehicle, the more preferentially the data that the vehicle sends to the cloud is processed.
Specifically, if the remote control server receives the terminal use state signal sent by the terminal, the terminal use state signal is sent to the shadow server, and the terminal use state signal carries the second vehicle identifier. After receiving the terminal use state signal sent by the remote control server, the shadow server can determine a corresponding second mapping module according to the second vehicle identifier, mark the service state priority of the vehicle in the second mapping module as the first priority, and store the first priority.
Fig. 2 shows a flow chart of a service state priority generation step of a vehicle according to an embodiment of the present invention. Referring to fig. 2, the service state priority generation step of the vehicle may be implemented as follows:
in step S202, the remote control server receives the terminal usage status signal sent by the terminal, and sends the terminal usage status signal to the shadow server. The terminal usage status signal carries a second vehicle identification (i.e., the vehicle identification of the terminal corresponding to the vehicle).
In this step, when the corresponding application program on the terminal is triggered or used (for example, the user opens the application program on the terminal or clicks any operation button in the user interface of the application program, etc.), a terminal usage status signal indicating that the application program of the terminal is being used by the user is generated, and a communication interface between the application program and the remote control server is automatically invoked to send the terminal usage status signal to the remote control server. Further, after receiving the terminal usage status signal sent by the terminal, the remote control server sends the terminal usage status signal to the shadow server through the kafka message channel.
In step S204, after receiving the terminal usage status signal sent by the remote control server, the shadow server determines a corresponding second mapping module according to the second vehicle identifier, and marks the service status priority of the vehicle in the second mapping module as the first priority.
In addition, since the time for which the user uses the application of the terminal is generally limited, the use state of the terminal may be changed after a certain period of time. Therefore, in one embodiment, after receiving the terminal usage status signal, the shadow server may further monitor whether the terminal usage status signal is received again within a specified time by using the second mapping module corresponding to the second vehicle identifier carried by the terminal usage status signal. If not, the shadow server marks the service state priority of the vehicle in the second mapping module as a second priority. The first priority is higher in priority than the second priority. The first priority and the second priority herein may be expressed in numerals, characters, etc. which are agreed in advance, for example, the first priority may be expressed by "1", "a", or "in use", etc., and the second priority may be expressed by "2", "B", or "unused", etc. The shadow server no longer receives the terminal usage status signal for the terminal within the specified time, which is most likely to indicate that the user is not currently using the application of the terminal. The service state priority of the corresponding vehicle is marked from the first priority to the second priority after the condition is detected, so that the processing priority of the vehicle state data reported by the corresponding vehicle is reduced, and the problem of delay in vehicle state storage is further relieved.
Fig. 3 is a flowchart of a method for reporting vehicle status data according to another embodiment of the present invention. Referring to fig. 3, in this embodiment, the shadow server determines, by executing step S102 and step S104, a service status priority of the vehicle corresponding to the first vehicle identifier carried by the received vehicle status data. The determined service status priority of the vehicle may be the first priority or the second priority.
Accordingly, step S106 may be further implemented as step S306: if the service state priority of the vehicle is the first priority, adding a first tag to the vehicle state data, and sending the vehicle state data to a remote control server through a first data channel corresponding to the first tag. And if the service state priority of the vehicle is the second priority, adding a second tag to the vehicle state data, and transmitting the vehicle state data to the remote control server through a second data channel corresponding to the second tag. The vehicle state data in the first data channel is sent to the remote control server in preference to the vehicle state data in the second data channel, and the vehicle state data is processed by the remote server according to the service requirement and then stored in a cache of the remote server.
In a specific embodiment, the first data channel may be a dockmq message channel corresponding to topic of the first tag and the second data channel may be a dockmq message channel corresponding to topic of the second tag, where topic specifies the content and format of the message transmission, and dockmq is a distributed message middleware.
More specifically, the first tag may be vip for representing higher priority data, and the second tag may be common for representing lower priority data. As such, if the service status priority of the vehicle is the first priority (indicating that the use status of the application of the terminal to which the vehicle corresponds is in use), the vehicle status data is transmitted to the remote control server using the dockmq message channel corresponding to the topic of the vip tag. If the service status priority of the vehicle is a second priority (indicating that the application of the terminal to which the vehicle corresponds is not in use), the vehicle status data is transmitted to the remote control server using a dockmq message channel corresponding to the topic of the common tag. Therefore, the reported vehicle state data are classified by the topic according to the priority, and the classification processing of the vehicle state data of the vehicle is realized.
The scheme of the invention marks the service state priority of the vehicle according to the use state of the terminal corresponding to the vehicle, and can ensure that the vehicle state data reported by the vehicle corresponding to the terminal in use is processed preferentially. Since the number of users using the terminal is small even during the peak period, and accordingly the number of reported data (such as the reported data of the vip tag) of the vehicle to be preferentially processed (i.e., the first priority) is small, the processing capacity of the remote control server is fully sufficient to cope with the situation without causing delay, thereby alleviating and even solving the problem of delay in storing the state of the vehicle. For the reported data (such as the reported data of the common tag) of the vehicle which does not need to be processed preferentially (namely, the second priority), the reported data can be accumulated in the message queue of the dockmq in the peak period, and the data can be consumed by utilizing the peak clipping function of the dockmq after the peak period.
Correspondingly, the embodiment of the invention also provides a vehicle state checking method.
Fig. 4 shows a flow diagram of a method of viewing a vehicle state according to an embodiment of the invention. The checking method is applied to a remote control server of the cloud. Referring to fig. 4, the viewing method may include at least the following steps S402 to S406.
In step S402, a vehicle state checking request sent by the terminal is received, where the vehicle state checking request carries a third vehicle identifier.
In this step, for viewing requests of different vehicle states, the terminal may call a corresponding interface between an application program of the terminal and the remote control server, and send the vehicle state viewing request to the remote control server. For example, for a vehicle state viewing request to view the closing of a door window, the terminal may invoke an interface between an application of the terminal and a remote control server to view the state of the door window, and send the vehicle state viewing request to the remote control server.
Step S404, according to the third vehicle identification, acquiring vehicle state data corresponding to the third vehicle identification from the cache of the remote control server. The vehicle state data mentioned herein are reported to the remote control server by the reporting method of the vehicle state data introduced by any embodiment or the combination of embodiments, and then stored in the cache of the remote control server after being processed.
Step S406, the vehicle state data is transmitted to the terminal as a result of responding to the vehicle state check request.
In this embodiment, when the user wishes to view the vehicle state through the terminal, the remote control server acquires the reported vehicle state data through the data channel corresponding to the service state priority of the vehicle and returns the reported vehicle state data to the terminal, so that the terminal can quickly acquire the vehicle state data, thereby ensuring that the user can view the current state of the vehicle through the terminal in real time without delay.
Fig. 5 shows a flow chart of a method of viewing a vehicle state according to another embodiment of the invention. The viewing method is applied to the terminal. Referring to fig. 5, the viewing method may include at least the following steps S502 to S504.
Step S502, a vehicle state checking request is sent to a remote control server of the cloud end, wherein the vehicle state checking request carries a third vehicle identifier.
The manner in which the terminal sends the vehicle status viewing request to the remote control server is as described above and is not repeated.
Step S504, vehicle state data transmitted by the remote control server in response to the vehicle state viewing request is received. The vehicle state data mentioned herein are reported to the remote control server by the reporting method of the vehicle state data described in any of the foregoing embodiments or combinations of embodiments.
The terminal can also display the received vehicle state data to the user so that the user can timely see the vehicle state.
The vehicle state data reported by the vehicle is classified according to the service state priority of the vehicle, and particularly, the service state priority of the vehicle is marked according to the use state of the terminal corresponding to the vehicle, so that the vehicle state data reported by the vehicle corresponding to the terminal in use can be preferentially processed.
Based on the same inventive concept, the embodiment of the invention also provides a system for reporting the vehicle state data. Fig. 6 shows a schematic structural diagram of a vehicle status data reporting system 10 according to an embodiment of the present invention. Referring to fig. 6, the reporting system 10 may include at least a remote control server 100, a shadow server 200 in communication with the remote control server 100, and a plurality of vehicles 300 in communication with the shadow server 200. The remote control server 100 and the shadow server 200 are installed in the cloud. The vehicle 300 reports vehicle status data to the shadow server 200, the vehicle status data carrying a first vehicle identification. The shadow server 200 determines the service state priority of the vehicle 300 corresponding to the first vehicle identifier according to the first vehicle identifier carried by the vehicle state data, and transmits the vehicle state data to the remote control server 100 through a data channel corresponding to the service state priority of the vehicle 300. The remote control server 100 receives the vehicle state data transmitted from the shadow server 200. Further, the remote control server 100 may also store vehicle state data to the cloud.
In the reporting system of the vehicle state data provided by the embodiment of the invention, the shadow server 200 determines the service state priority of the vehicle 300 corresponding to the first vehicle identifier according to the first vehicle identifier carried by the received vehicle state data reported by the vehicle, and sends the vehicle state data to the remote control server 100 through the data channel corresponding to the service state priority of the vehicle 300, so that the reported vehicle state data can be classified according to the service state priority of the vehicle 300 reporting the data, and the data reported by the vehicle 300 with high service state priority can be processed preferentially, thereby alleviating or even solving the problem of delay in vehicle state storage.
Further, referring to FIG. 7, shadow server 200 may include a plurality of mapping modules 201. Each mapping module 201 corresponds to a vehicle identifier and stores the service status priority of the vehicle 300 corresponding to the vehicle identifier. In this case, the shadow server 200 is further configured to determine a first mapping module (one of the plurality of mapping modules 201) corresponding to the first vehicle identifier according to the first vehicle identifier carried by the vehicle status data, and then obtain the service status priority corresponding to the first vehicle identifier from the corresponding first mapping module.
Further, the mapping module 201 stores service status priorities of vehicles corresponding to the vehicle identifications, the service status priorities being generated by:
the shadow server 200 receives the terminal usage status signal sent by the remote control server 100, where if the remote control server 100 receives the terminal usage status signal sent by the terminal 400, the terminal usage status signal is sent to the shadow server 200, and the terminal usage status signal carries the second vehicle identifier.
