Description
Technical Field
The invention relates to the field of SOA (service oriented architecture), in particular to a method, a device and a system for transferring functions to services based on a central gateway, electronic equipment and a storage medium.
Background
In recent years, with the rapid development of the ethernet communication technology of automobiles, applications such as intelligent driving, automatic diagnosis, entertainment and the like are more and more abundant, and Service-Oriented Architecture (SOA) is more and more popular. Compared with the traditional functional automobile electronic software architecture, the SOA can convert the functions of various sensors and actuators in an automobile into services so as to supply different application software with information of the sensors or controllers required by calling, and after certain calculation and logic judgment, the SOA sends instructions to the corresponding actuators or controllers, and the actuators or controllers execute corresponding actions.
At present, the method for implementing SOA is mainly based on the service-Oriented middle layer software protocol (SOME/IP) of ethernet. SOME/IP provides a set of general protocols, the vehicle-mounted controller provides the protocols to convert the functions of the vehicle-mounted controller into services and provide the services to other controllers through a network for use, and the SOME/IP is an IP-based scalable middleware for transmitting service messages and can be suitable for different operating systems. The SOME/IP divides the vehicle-mounted controller into a service end and a client end, and for one controller, when the controller provides service, the controller is the service end; it is a client when it invokes the services of the other controller. A Service is a combination of zero or more Event events, zero or more Method methods, and zero or more Field fields containing at least one Event or one Method or one Field. An Event is a unidirectional data transmission sent by the server to the client, and an Event can be sent periodically or Event-wise (aperiodically). A Method is a Method, program, function, or subroutine that may be called by a client. Fields is a combination of get Getter, set Getter, and notify Notifier, and includes at least one Getter or Notifier. SOME/IP is an intermediate layer protocol, shown in FIG. 1, located between the application layer and TCP/IP.
The method for realizing SOA by adopting SOME/IP mainly has the following defects:
(1) the SOME/IP protocol contains event type signals and periodic type signals, the protocol implementation is complex, and a controller and an application program must be required to support the protocol;
(2) SOME/IP is an open standard, only frames such as a header and the like are defined, the specific content of a protocol is customized by each host factory, and for an application program, the SOME/IP protocol which needs to be compatible with different host factories has considerable difficulty;
(3) when all application layer software simultaneously subscribe the same message, the load of the network is increased;
(4) in the existing mode, the service of the application program acquisition sensor or the controller depends on vehicle-mounted network communication, and the vehicle-mounted network communication is difficult to guarantee real-time performance.

A specific embodiment of a method for transferring a function to a service based on a central gateway according to the present application is described below, and fig. 3 is a schematic flowchart of a method for transferring a function to a service based on a central gateway according to the embodiment of the present application. The order of steps recited in the embodiments is only one of many possible orders of execution and does not represent the only order of execution, and in actual execution, the steps may be performed sequentially or in parallel as in the embodiments or methods shown in the figures (e.g., in the context of parallel processors or multi-threaded processing). Specifically, as shown in fig. 3, the method includes:
s301: the shared memory module acquires a write data instruction issued by the application layer by using the service interface.
In the embodiment of the application, after the central gateway is powered on and initialized, the function-to-service layer is started, that is, the data processing module and the shared memory module are controlled to be in a working mode, wherein the shared memory module acquires an instruction issued by the application layer by using the service interface, and determines the type of the instruction, and the type of the instruction may be a write data instruction or a read data instruction. In an alternative embodiment, the shared memory module determines that the instruction is a write data instruction, where the write data instruction includes a first object, execution data corresponding to the first object, and a function domain to which the first object belongs.
It should be noted that, for the application layer, the service interfaces for issuing the instructions are all unified, so that the vehicle-mounted server using the central gateway can have good compatibility, and the technology developer can be prevented from implementing a complex SOME/IP protocol.
S303: the shared memory module analyzes the data writing instruction to obtain a first object in the data writing instruction, execution data corresponding to the first object and a functional domain to which the first object belongs.
In the embodiment of the present application, the first object may include one type of on-board electronic controller, and may also include multiple types of on-board electronic controllers. For example, the first object may include an actuator, the first object may also include a first controller, and the first object may also include an actuator and a first controller. The first object obtained by sharing the memory module is specifically an on-board electronic controller capable of realizing the application layer setting function.
In this embodiment of the present application, the executing data specifically includes an executing action and an executing cycle corresponding to the executing action.
In the embodiment of the present application, the functional domain to which the first object belongs may specifically include, but is not limited to, a comfort domain, an entertainment domain, a chassis domain, a power domain, and a hybrid domain.
S305: and the shared memory module stores the execution data corresponding to the first object in the read shared memory according to the function domain to which the first object belongs.
In the embodiment of the present application, the shared memory module is a data interaction medium of the data processing module and the service interface, and the general structure can be divided into two main categories (with respect to the data processing module) of a read shared memory and a write shared memory, where the data processing module and the service interface have different permissions for reading the shared memory and writing the shared memory. For example, if the data processing module has a read-write permission for reading or writing any one of the shared memories, the service interface has a read-write permission for reading or writing the other of the shared memories, or if the data processing module has a read-write permission for reading or writing any one of the shared memories, the service interface has a read-write permission for reading or writing the other of the shared memories.
Wherein the read shared memory and the write shared memory are provided with a plurality of different functional domains, such as the comfort domain, the entertainment domain, the chassis domain, the power domain, and the hybrid domain mentioned above, and further each functional domain is further divided into a plurality of different periodic regions, such as 10ms, 50ms, 100ms, 1s, and event (non-periodic) periodic regions. Specifically, as shown in fig. 4, a schematic structural diagram of a shared memory module is provided.
S307: and if the read shared memory is detected to be stored with the updating data, the data processing module acquires the updating data.
In the embodiment of the application, the data processing module monitors the shared memory in real time, and once the data processing module detects that the update data are stored in the read shared memory, the data processing module acquires the update data in the read shared memory in real time. The update data includes a first object and execution data corresponding to the first object. Likewise, the first object may include one type of on-board electronic controller, and may also include multiple types of on-board electronic controllers. For example, the first object may include an actuator, the first object may also include a first controller, and the first object may also include an actuator and a first controller. The first object obtained by sharing the memory module is specifically an on-board electronic controller capable of realizing the application layer setting function.
S309: the data processing module determines a first object in the update data and the execution data corresponding to the first object.
In the embodiment of the application, the data processing module obtains the update data and performs analysis operation on the update data to obtain a first object in the update data and execution data corresponding to the first object.
S311: the data processing module determines a communication interface identifier corresponding to the first object;
in the embodiment of the present application, each of the first objects, i.e. each of the electronic controllers directly or indirectly connected to the central gateway, has a corresponding communication interface. In an alternative embodiment, each communication interface is associated with a corresponding electronic controller in the form of a communication interface identifier in the data processing module, and the data processing module, after determining the first object, may determine the communication interface identifier associated therewith from the first object.
In another optional implementation manner, when the shared memory module stores the execution data corresponding to the first object in the read shared memory according to the functional domain to which the first object belongs, the communication interfaces corresponding to each object are stored in the read shared memory together in the form of a communication interface identifier. The data processing module can directly determine the communication interface identifier corresponding to the first object.
S313: the data processing module sends execution data to the first object by using the communication interface corresponding to the communication interface identification, so that the first object executes the execution action according to the execution cycle.
In this embodiment, the hardware part of the communication interface may include an ethernet of the central gateway, a CAN, a LIN, a FlexRay and other vehicle-mounted communication interfaces, because the ethernet CAN provide a large communication bandwidth, the ethernet is mainly used for a backbone network to connect the central gateway and a large number of actuators and first controllers; the central gateway supports a plurality of CAN interfaces, and the CAN has wide communication application in the vehicle and CAN meet various application requirements; LIN can be used to connect some low speed actuators and controllers, FlexRay can provide the controller to the FlexRay communication. Thus, the central gateway CAN specifically provide 6-way ethernet interface, 8-way CAN interface, 10-way LIN and 2-way FlexRay.
By adopting the method for transferring the function to the service based on the central gateway, the data writing command issued by the application layer can be obtained without a uniform service interface provided by the central gateway, a complex SOME/IP protocol does not need to be realized, data interaction can be carried out in a chip by the application layer and the work transfer service layer, and the method has rapidness and real-time performance compared with network communication.
A specific embodiment of a method for transferring a function to a service based on a central gateway according to the present application is described below, and fig. 5 is a schematic flowchart of a method for transferring a function to a service based on a central gateway according to the present application, where the present specification provides the method operation steps as shown in the embodiment or the flowchart, but the method may include more or less operation steps based on conventional or non-inventive labor. The order of steps recited in the embodiments is only one of many possible orders of execution and does not represent the only order of execution, and in actual execution, the steps may be performed sequentially or in parallel as in the embodiments or methods shown in the figures (e.g., in the context of parallel processors or multi-threaded processing). Specifically, as shown in fig. 5, the method includes:
s501: the data processing module acquires a data reading instruction issued by an application layer; the read data instruction includes a second object.
In the embodiment of the application, after the central gateway is powered on and initialized, the function-to-service layer is started, that is, the data processing module and the shared memory module are controlled to be in a working mode, wherein the shared memory module acquires an instruction issued by the application layer by using the service interface, and determines the type of the instruction, and the type of the instruction may be a write data instruction or a read data instruction. In an alternative embodiment, the shared memory module determines that the command is a read data command, and the read data command includes the second object.
S503: and the data processing module determines the communication interface identifier corresponding to the second object.
In the embodiment of the present application, as the communication interface identifier corresponding to the first object is determined, each object in the second object, that is, each electronic controller directly or indirectly connected to the central gateway, also has a corresponding communication interface. In an alternative embodiment, each communication interface is associated with the corresponding electronic controller in the form of a communication interface identifier in the data processing module, and the data processing module may determine the communication interface identifier associated with the second object according to the second object after determining the second object.
S505: and the data processing module sends a data acquisition request to the second object by using the communication interface corresponding to the communication interface identifier.
In the embodiment of the present application, as mentioned above, the hardware part of the communication interface may include the ethernet of the central gateway, the on-board communication interfaces such as CAN, LIN, FlexRay and the like, because the ethernet CAN provide a large communication bandwidth, and therefore the ethernet is mainly used for the backbone network to connect the central gateway and the large number of actuators and the first controller; the central gateway supports a plurality of CAN interfaces, and the CAN has wide communication application in the vehicle and CAN meet various application requirements; LIN can be used to connect some low speed actuators and controllers, FlexRay can provide the controller to the FlexRay communication. Thus, the central gateway CAN specifically provide 6-way ethernet interface, 8-way CAN interface, 10-way LIN and 2-way FlexRay.
S507: and the data processing module receives data acquisition feedback sent by the second object.
In the embodiment of the application, the data processing module receives data acquisition feedback sent by the second object by using the communication interface, and the data feedback contains identification information corresponding to the second object in the data reading instruction and state data of the second object. The second object may include one type of on-board electronic controller, and may also include multiple types of on-board electronic controllers. For example, the second object may include a sensor, the second object may also include a second controller, and the first object may also include a sensor and a second controller. The second object obtained by the shared memory module is specifically an on-board electronic controller which can realize that the application layer sets data to be acquired.
Continuing with the description of the first controller mentioned above, it should be understood that the first controller may be a subset of the second controller, and that the first controller may be a subset of the second controller, assuming that the second controller is embodied as all of the onboard electronic controllers in the vehicle and the application layer setting function only needs to control a portion of the onboard electronic controllers. Of course, the first controller and the second controller may not have an intersection, and it is assumed that the function set by the application layer needs to control part of the on-board electronic controllers, and the function set by the application layer needs to collect data is completely different from the function set by the application layer. For example, the function set by the application layer needs to control the operation of the windshield water sprayer, and in this case, the information data of the vehicle-mounted temperature sensor does not need to be acquired.
In this embodiment, in a specific implementation where an optional data processing module receives data acquisition feedback sent by a second object, the data processing module does not need to send a data acquisition request to the second object, but sets, in an initialization setting, an update period of state data of the second object according to identification information of the second object, that is, the update period of the state data of the second object mentioned below, and automatically sends the state data to the data processing module at regular time, so as to update the state data in the read shared memory corresponding to the second object.
S509: the data processing module determines identification information of the second object and status data of the second object in the data acquisition feedback.
In the embodiment of the application, the data processing module receives the data acquisition feedback sent by the second object, and analyzes the data acquisition feedback to obtain the identification information of the second object and the state data of the second object in the data acquisition feedback. Wherein the identification information of the second object may include a function domain to which the second object belongs and an update period of the state data. The state data of the second object may specifically be an operating state of the sensor and/or the second controller, or may be information data acquired by the sensor and/or the second controller. For example, the rainfall sensor acquires information data of "rain outdoors".
As a specific example, if the data processing module determines that the second object in the data acquisition feedback includes a vehicle-mounted music switch and a vehicle-mounted air conditioner switch, where the identification information corresponding to the vehicle-mounted music switch indicates that the functional domain is an entertainment domain, the update cycle is an event, and the corresponding state data indicates that the vehicle-mounted music switch is in an off state. The identification information corresponding to the vehicle-mounted air-conditioning switch is that the belonging functional domain is a comfortable domain, the updating period is an event, and the corresponding state data is that the vehicle-mounted air-conditioning switch is in a closed state.
S511: and the data processing module stores the state data of the second object in the write shared memory according to the function domain to which the second object belongs and the update cycle of the state data.
