Example one
Fig. 1 is a flowchart illustrating a communication method according to an embodiment of the present invention, where the embodiment is applicable to a situation where communication terminals of controllers in an intelligent vehicle communicate with each other, and the method may be performed by a communication device, where the communication device may be implemented in a form of hardware and/or software, and the communication device may be configured in an electronic device such as a computer or a server.
As shown in fig. 1, the method of the present embodiment includes:
s110, in the process that the first controller communication end and the second controller communication end communicate based on the target communication protocol, a first communication role of the first controller communication end and a second communication role of the second controller communication end are determined.
The target communication protocol is a rule and an agreement which are required to be followed by the first controller communication terminal and the second controller communication terminal to complete communication or service. In the implementation of the present invention, the target communication protocol may be a Data Distribution Service (DDS) protocol. The DDS protocol is adopted for communication, so that the data can be distributed efficiently and flexibly in real time, and various distributed real-time communication application requirements can be met. Accordingly, the communication based on the target communication protocol may be ethernet communication based on the DDS protocol.
The first controller communication terminal may be a controller communication terminal based on service communication, such as a microprocessor unit (MPU) terminal. The second controller communication terminal may be a controller communication terminal based on signal communication, such as a Micro Control Unit (MCU) terminal. The first communication role is the communication role of the communication end of the first controller. The second communication role is the communication role of the communication end of the second controller. The communication roles may include a data receiver and a data sender.
Specifically, in the process of performing ethernet communication between the first controller communication terminal and the second controller communication terminal based on the target communication protocol, it may be determined whether the first communication role of the first controller communication terminal is a data sender or a data receiver, and it may be determined whether the second communication role of the second controller communication terminal is a data receiver or a data sender. It is to be understood that if the first communication role is a data sender, then the second communication role is a data receiver. Accordingly, if the first communication role is a data receiver, the second communication role is a data sender.
Illustratively, the first controller communication end is an MPU end, the second controller communication end is an MCU end, and the target communication protocol is a DDS protocol. In the process that the MPU end and the MCU end carry out Ethernet communication based on the DDS protocol, whether the communication roles of the MPU end and the MCU end are a data sending party or a data receiving party can be determined.
And S120, if the first communication role is a data sender and the second communication role is a data receiver, determining the communication service to be sent of the communication end of the first controller, carrying out serialization processing on the communication service to be sent to obtain an identifiable communication message of the communication end of the second controller, and sending the identifiable communication message to the communication end of the second controller based on a target communication protocol.
The communication service to be sent can be understood as a service that the communication terminal of the first controller needs to send to the communication terminal of the second controller. The identifiable communication message may be a message identifiable by the communication terminal of the second controller, which is obtained by performing serialization processing on the communication service to be sent of the communication terminal of the first controller. The serializing the communication service to be transmitted may be a serializing of the communication service to be transmitted by a serializing alignment algorithm.
Specifically, if the first communication role is a data sender and the second communication role is a data receiver, it may be determined that the first controller communication end needs to send a communication service to be sent to the second controller communication end. After the communication service to be sent is determined, the communication service to be sent can be serialized by calling a serialization alignment algorithm. And then the identifiable communication message of the second control communication terminal can be obtained. Therefore, the recognizable communication message can be sent to the second controller communication terminal based on the target communication message, so that the second controller communication can recognize the communication data contained in the recognizable communication message after receiving the recognizable communication message.
Along the above example, in the process of transmitting the communication service of the MPU side to the MCU side, the serialization processing of the communication service of the MPU side may be performed. Therefore, the recognizable communication message of the MCU terminal can be obtained. And then the identifiable message can be sent to the MCU terminal.
S130, if the first communication role is a data receiver and the second communication role is a data sender, determining a communication message to be sent of the communication end of the second controller, performing deserialization processing on the communication message to be sent to obtain identifiable communication service of the communication end of the first controller, and sending the identifiable communication service to the communication end of the first controller based on a target communication protocol.
The communication message to be sent can be understood as a message that the communication end of the second controller needs to send to the communication end of the first controller. The identifiable communication service may be a service identifiable by the communication end of the first controller obtained by performing deserialization processing on the communication packet to be sent at the communication end of the second controller. The deserializing of the communication message to be sent may be deserializing of the communication message to be sent by a deserializing alignment algorithm.
Specifically, if the first communication role is a data receiver and the second communication role is a data sender, it may be determined that the communication end of the second controller needs to send a to-be-sent communication packet to the communication end of the first controller. After the communication message to be sent is determined, the deserializing processing can be carried out on the communication message to be sent by calling the deserializing alignment algorithm corresponding to the serializing alignment algorithm, so that identifiable communication service which can be identified by the communication end of the first controller can be obtained. And further, the recognizable communication service can be sent to the first controller communication terminal based on the target communication protocol, so that the first controller communication terminal can recognize the communication data in the recognizable communication service after receiving the recognizable communication service.
Along the above example, in the process of sending the communication message of the MCU to the MPU, the communication message of the MCU may be deserialized. So that recognizable communication services of the MPU side can be obtained. And then the identifiable communication service can be transmitted to the MPU side.
It should be noted that, in the embodiment of the present invention, in the implementation of the present invention, serialization may be used to facilitate storing data or transmitting data in a network, and deserialization is reverse engineering of serialization and may be used to recover serialized data.
In addition, although the embodiments of the present invention describe S110, S120, and S130, in a specific implementation process, the execution sequence of S120 and S130 may be arbitrary. It can be understood that, in the operation S130, after determining the communication packet to be sent at the communication end of the second controller, the communication packet to be sent may be serialized, so that the identifiable communication service at the communication end of the first controller can be obtained. Accordingly, in the re-execution of S120 operation, after determining the communication service to be sent of the first controller communication end, the communication service to be sent may be deserialized, so that the identifiable communication packet of the second controller communication end may be obtained.
According to the technical scheme of the embodiment of the invention, in the process of communication between the first controller communication terminal and the second controller communication terminal based on the target communication protocol, whether the first controller communication terminal and the second controller communication terminal are data sending terminals or data receiving terminals can be determined by determining the first communication role of the first controller communication terminal and the second communication role of the second controller communication terminal. After the communication role is determined, if the first communication role is a data sender and the second communication role is a data receiver, the communication service to be sent of the communication end of the first controller can be determined, and then the communication service to be sent can be subjected to serialization processing, so that the identifiable communication message of the communication end of the second controller can be obtained, and the identifiable communication message can be sent to the communication end of the second controller based on the target communication protocol. If the first communication role is a data receiver and the second communication role is a data sender, the communication message to be sent of the communication end of the second controller can be determined, and then the communication message to be sent can be subjected to deserialization processing, so that the identifiable communication service of the communication end of the first controller can be obtained, and then the identifiable communication service can be sent to the communication end of the first controller based on the target communication protocol. The problem of among the prior art can't realize intercommunication between each controller communication terminal among the intelligent driving vehicle, realize intercommunication between each controller communication terminal among the intelligent driving vehicle to reach the technical effect who promotes the communication performance of vehicle.
Example two
Fig. 2 is a flowchart of a communication method according to a second embodiment of the present invention, where on the basis of the foregoing embodiment, optionally, the determining a communication service to be sent of the communication end of the first controller includes: determining the communication service type of the communication between the first controller communication terminal and the second controller communication terminal; and when the communication service type is a service event type, determining to-be-sent communication data of the first controller communication terminal, performing abstraction processing on the to-be-sent communication data to obtain an event communication service of the service event type, and using the event communication service as the to-be-sent communication service of the first controller communication terminal. The technical terms that are the same as or corresponding to the above embodiments are not repeated herein.
As shown in fig. 2, the method of this embodiment specifically includes:
s210, in the process that the first controller communication end and the second controller communication end communicate based on the target communication protocol, a first communication role of the first controller communication end and a second communication role of the second controller communication end are determined.
S220, if the first communication role is a data sender and the second communication role is a data receiver, determining the communication service type of the communication between the first controller communication end and the second controller communication end.
The communication service type can represent the type of the service received or sent by the communication terminal of the first controller. The service received or transmitted by the first controller communication terminal may include at least one of an event, a method, and a field. Specifically, when the service received or sent by the communication end of the first controller is an event, the communication service type is a service event type; or, when the service received or sent by the first controller communication terminal is a method, the communication service type is a service method type; or, when the service received or sent by the communication terminal of the first controller is field, the communication service type is the service field type.
Specifically, if the first communication role is a data sender and the second communication role is a data receiver, the communication service type of the communication service to be sent, which is sent by the first controller communication end to the second controller communication end, may be determined, that is, it may be determined whether the service to be sent, which is sent by the first controller communication end to the second controller communication end, is an event, a method, or a field.
And S230, when the communication service type is the service event type, determining to-be-sent communication data of the communication end of the first controller, performing abstraction processing on the to-be-sent communication data to obtain an event communication service of the service event type, and using the event communication service as the to-be-sent communication service of the communication end of the first controller.
The communication data to be sent may be an instruction or a message sent by the first controller communication terminal to the second controller communication terminal.
Specifically, when the communication service type is a service event type, it can be understood that when the communication service to be sent, which is required to be sent by the communication terminal of the first controller to the communication terminal of the second controller, is an event, the communication data to be sent of the communication terminal of the first controller can be determined. After determining the communication data to be sent, the communication data to be sent at the communication end of the first controller may be abstracted into an event. And then an event communication service of the service event type can be obtained. Therefore, the event communication service can be used as a communication service to be sent of the communication terminal of the first controller.
S240, carrying out serialization processing on the communication service to be sent to obtain the identifiable communication message of the communication end of the second controller, and sending the identifiable communication message to the communication end of the second controller based on the target communication protocol.
And S250, if the first communication role is a data receiver and the second communication role is a data sender, determining a communication message to be sent of the communication end of the second controller, performing deserialization processing on the communication message to be sent to obtain identifiable communication service of the communication end of the first controller, and sending the identifiable communication service to the communication end of the first controller based on a target communication protocol.
It can be understood that, if the communication service type of the communication between the first controller communication terminal and the second controller communication terminal is a service event type, the communication packet to be sent of the second controller communication terminal may be determined in the following manner:
and determining the initial message to be sent of the second and controller communication terminals, and further performing message packaging processing on the initial message to be sent based on the target communication protocol, so that the packaged message can be obtained. And then the packaged message can be used as a communication message to be sent of a communication end of the second controller. The initial message to be sent may be a message generated based on an original communication protocol of the communication end of the second controller, where the original communication protocol may be a CAN protocol or a LIN protocol.
The message format of the initial message to be sent may be communication protocol binding of signals such as a CAN protocol or a LIN protocol and splicing of signal-based payloads. The message format of the communication message to be sent can be DDS communication protocol binding and signal-based payload splicing. It should be noted that, the concrete representation form of the splicer used for splicing may be various, such as "+" and "-", and is not limited in this respect.
According to the technical scheme of the embodiment of the invention, the communication service type of communication between the first controller communication terminal and the second controller communication terminal is determined. When the communication service type is the service event type, determining to-be-sent communication data of the first controller communication end, performing abstraction processing on the to-be-sent communication data to obtain an event communication service of the service event type, and taking the event communication service as the to-be-sent communication service of the first controller communication end.
EXAMPLE III
Fig. 3 is a flowchart of a communication method according to a third embodiment of the present invention, and based on the foregoing embodiment, the communication service to be sent of the communication end of the first controller is further optimized. And further optimizing the communication message to be sent of the communication end of the second controller. The technical terms that are the same as or corresponding to the above embodiments are not repeated herein.
As shown in fig. 3, the method of this embodiment specifically includes:
s301, in the process that the first controller communication end and the second controller communication end communicate based on the target communication protocol, a first communication role of the first controller communication end and a second communication role of the second controller communication end are determined.
S302, if the first communication role is a data sender and the second communication role is a data receiver, determining the communication service type of the communication between the first controller communication end and the second controller communication end.
S303, when the communication service type is the service method type and the first controller communication end does not store the data calculation method, determining a service method request of the first controller communication end, generating a communication message with the recognizable method of the second controller communication end based on the service method request, and sending the communication message with the recognizable method to the second controller communication end.
The service method request may be understood as a request that the first controller communication terminal sends a service method to the second controller communication terminal, and may be used to request a data calculation method stored in the second controller communication terminal. The service method request may carry at least one piece of data to be calculated and a method identifier of a data calculation method used for calculating the data to be calculated.
Specifically, when the communication service type is the service method type and the first controller communication terminal does not store the data calculation method, it can be understood that, when the communication service to be sent, which the first controller communication terminal needs to send to the second controller communication terminal, is the method and the first controller communication terminal does not store the data calculation method, a service method request carrying the data to be calculated can be generated at the first controller communication terminal. And further, the recognizable method communication message of the second controller communication end can be generated based on the service method request and the data to be calculated carried by the service method request. Therefore, the recognizable method communication message can be sent to the second controller communication end, so that the second controller communication end receives the recognizable method communication message and recognizes the service method request and the data to be calculated in the recognizable method communication message.
S304, when the second controller communication terminal identifies the service method request and the data to be calculated in the identifiable method communication message, determining a target calculation method corresponding to the service method request in the data calculation method, and obtaining a calculation result according to the target calculation method and the data to be calculated.
The target calculation method can be understood as a data calculation method which needs to calculate data to be calculated currently.
Specifically, when the second controller communication terminal identifies the service method request and the data to be calculated in the identifiable method communication message, the target calculation method corresponding to the service method request in the data calculation method may be determined. And then the data to be calculated can be substituted into the target calculation method. So that a calculation result can be obtained.
S305, abstracting the calculation result into a method communication service corresponding to the service method type, and taking the method communication service as a communication service to be sent of the communication end of the first controller.
A method communication service may be understood as a communication service of a service method type, among others.
Specifically, after the calculation result is obtained, the calculation result may be abstracted based on the service method type. And then, method communication service corresponding to the service method type can be obtained. Therefore, the method communication service can be used as the communication service to be sent of the communication terminal of the first controller.
S306, carrying out serialization processing on the communication service to be sent to obtain the identifiable communication message of the communication end of the second controller, and sending the identifiable communication message to the communication end of the second controller based on the target communication protocol.
S307, if the first communication role is a data receiving party and the second communication role is a data sending party, determining the communication service type of the communication between the first controller communication end and the second controller communication end.
S308, when the communication service type is the service method type, the communication service method is stored in the first controller communication end, and the communication service method is not stored in the second controller communication end, determining a data communication message sent by the second controller communication end in the first controller communication end, and obtaining the identifiable method request and the data to be calculated of the first controller communication end based on the data communication message.
The data to be calculated can be loaded in a data communication message sent by a second controller communication terminal in the first controller communication terminal. The recognizable method request may be understood as a communication service method request for calculating data to be calculated in the communication side of the second controller.
