It should be apparent that the aspects described herein may be embodied in a wide variety of forms and that any specific structure and/or function described herein is merely illustrative. Based on the present disclosure, one skilled in the art will appreciate that one aspect described herein may be implemented independently of any other aspect, and that two or more of these aspects may be combined in various ways. For example, an apparatus may be implemented and/or a method practiced using any number of the aspects set forth herein.

Referring to fig. 1, according to an aspect of the present application, a message processing method is provided and applied to a first message processing module in a vehicle-mounted communication device, where the first message processing module has an association relationship with a first functional module in the vehicle-mounted communication device, and a plurality of second functional modules are disposed in the vehicle-mounted communication device, and each of the second functional modules is provided with a corresponding second message processing module.
The method comprises the following steps:

Step S330 does not respond to the first message or discards the first message.
In this embodiment, the distinction between "first" and "second" in the first functional module and the second functional module is only limited to clearly illustrate the specific technology of this embodiment. It is understood that the vehicle-mounted communication device may have a plurality of functional modules having the same or different functions therein, and the first functional module and the second functional module in the present embodiment refer to any two of the plurality of functional modules described above. Accordingly, the first message processing module and the second message processing module are similar to those described above, and only serve to distinguish their corresponding functional modules. It is to be understood to a certain extent that each functional module or at least some functional modules within the vehicle-mounted communication device is provided with a message processing module which corresponds exclusively to it. The first functional module and the second functional module may be implemented as a process, an application program, or the like in the in-vehicle processing device.
In this embodiment, the MPU in the TBox (vehicle-mounted communication device) is implemented based on an embedded Linux system, and the Linux kernel is provided with dbus, and accordingly, the first message processing module and the second message processing module are built by encapsulating the dbus.
The target message type corresponding to the first functional module can be simply understood as the message type of interest to the first functional module. The meaning of interest is that the first functional module will respond and process messages of the message type of interest. It does not take additional action without attention. The target message types corresponding to the first functional module may be plural.
According to the message processing method provided by the embodiment, the message type of the received first message can be determined through the first message processing module, and whether the first message is sent to the first functional module is determined according to whether the message type is the target message type corresponding to the associated first functional module or not. Therefore, the method and the device realize that the received first message is subjected to descreening through the independently arranged message processing module, and only the message required by the first functional module is sent to the first functional module, so that the first functional module only needs to directly process the received first message and does not need to distinguish and judge the received message. The processing pressure of the first functional module is reduced. Meanwhile, the first message processing module is used for receiving and primarily processing the first message, so that the problem of delay in processing the terminal or responding by the first functional module caused by receiving a new message can be avoided.
In an exemplary embodiment of the present application, the first message is sent by the second message processing module in a broadcast form.
In some technologies, communication between processes adopts a point-to-point mode to communicate, so that before a process of sending out a message is required to send out the message, the processes in the vehicle-mounted communication device are set inside; meanwhile, it is also determined that the process is required to process the message to be sent, and a communication connection with the target process is established in the network, so that point-to-point communication can be realized. The method occupies great processing capacity of the process, and has complicated flow and low efficiency.
In this embodiment, the first message (i.e., the message sent by the second functional module through the second message processing module) is sent directly through the broadcast. Therefore, when the second functional module sends out the message, the second functional module does not need to determine in advance who needs to process the message, does not need to establish a response communication channel, and only needs to label the message to be sent with the message type and then directly send the message. In this way, all processes in the vehicle-mounted communication device can theoretically receive the first message, and the first function module is used for taking an example, at this time, the first message processing module acts as a middleware, and can judge all received messages (first messages) in advance, determine whether the message type of the received messages is the target message type concerned by the corresponding first function module, and only if so, the message type is sent to the first function module. Therefore, even if the first message processing module can receive the message sent by all the functional modules, the computing resources of the corresponding first functional modules are not occupied, the overall processing speed is not influenced, and the computing amount of the functional modules for sending the message is reduced.
In an exemplary embodiment of the present application, the method further comprises:
receiving a second message sent by the first functional module;
and sending the second messages in a broadcast mode so that each second message processing module can acquire the second messages.
In this embodiment, when the first functional module needs to send the second message outwards, the first functional module only needs to directly send the second message to be sent to the first message processing module corresponding to the first functional module. The first message processing module transmits the received second message in the form of a broadcast. Therefore, the first functional module and the first message processing module do not need to judge to whom the second message is to be sent, and do not need to set any functional module in the vehicle-mounted communication module in the internal storage area and other positions in advance, and only the first functional module needs to add an identifier or a character capable of representing the message type of the second message in the position (set byte) set in the second message when the first functional module generates the second message. The operation amount is extremely low, and complicated logic judgment is not required.
In this embodiment, the second message is sent out by the first processing module in a broadcast manner, so that the sender does not need to know which functional modules are in the vehicle-mounted communication device, and does not need to determine who receives the second message. Therefore, even if the first functional module is newly arranged in the vehicle-mounted communication device, the communication system in the vehicle-mounted communication device can be directly compatible, and after the new functional module is added into the vehicle-mounted communication device, configuration files and the like in the interior of each functional module are not required to be modified so as to inform that the new functional module is added into the vehicle-mounted communication device. Therefore, efficient and concise new function module addition is realized.
Accordingly, in an exemplary embodiment of the present application, the determining the message type of the first message includes:
and acquiring target content of a setting field in the first message, wherein the target content is used for representing the message type of the first message.
The target content is a preset identifier or character capable of representing the message type, and in this embodiment, different message types are represented in a digital manner. All the functional modules in the vehicle-mounted communication device follow a unified message type representation mode, so that each functional module and each message processing module can distinguish and determine the message type of each message according to a unified standard.
In particular, the first message and the second message may include a message type field, a message length field, and a message content field therein. The message content field is used for storing an identifier or character representing the type of the message, the message length field represents the length of the message contained in the communication, and the message content field stores specific message content.
In an exemplary embodiment of the present application, before the receiving the first message sent by the second message processing module, the method further includes:
receiving registration information sent by the first functional module; the registration information comprises at least one target message type corresponding to the first functional module;
and storing the registration information.
The determining whether the message type is the target message type corresponding to the first functional module includes:
comparing the message type of the first message with the registration information, and determining whether the registration information has the same target message type as the message type of the first message.
In this embodiment, the first functional module may send registration information to the corresponding first message processing module at the set node. To inform the first message handling module of the type of target message of interest to itself. The first message processing module can judge whether the received first message needs to be sent to the first functional module according to the registration information. The registration message may exist in a vector, a set, a list or the like, and stores all target message types currently focused by the first functional module in the registration message. Meanwhile, the first functional module can also send a new registration message to the first processing module again after the function or the requirement of the first functional module is changed so as to update the registration information stored by the first message processing module.
Fig. 2 is a schematic diagram of a processing flow sequence among the first functional module, the first message processing module, the second functional module, and the second message processing module.
In an exemplary embodiment of the present application, the first message processing module is established for the vehicle-mounted communication device in response to the activation of the first functional module.
In this embodiment, the first message processing module is not a module that is always present, but is built in real time by calling a resource (such as dbus) in the vehicle-mounted communication device in response to the start of the first function module, and correspondingly, after the first function module is turned off, the first message processing module is also turned off, and the called resource is correspondingly released. Thus, when the first functional module does not work, the resource called by the first message processing module can be released to perform other works. The method realizes the dynamic adjustment of resources in the vehicle-mounted communication device and achieves the purpose of reasonable utilization of the resources. It should be noted that, since the first message processing module is released after the first functional module is turned off, after each time the first functional module is started and after the first message processing module is built, the first functional module needs to send registration information to the first message processing module, so that the first message processing module can work normally.
In an exemplary embodiment of the present application, after the sending the first message to the first functional module, the method further includes:
sending notification information to the first functional module;
the notification information is used for notifying the first functional module that the first message arrives.
In this embodiment, after the first message processing module sends the first message to the first functional module, the first message processing module sends notification information to the first functional module to inform the first functional module that the first message has arrived, so that the first functional module reads the first message in time for processing.
Accordingly, in an exemplary embodiment of the present application, after the sending notification information to the first functional module, the method further includes:
receiving feedback information sent by the first functional module;
the feedback information is sent to the first message processing module after the first functional module adds the first message to a message queue; the feedback information is used for notifying the first message processing module that the first message has been received, so that the first message processing module can continue to send messages to the first functional module.
In practical applications, the first message processing module will always continuously receive a plurality of messages, so that in order to make the messages orderly and effectively sent to the first functional module, the first message processing module will continue to send new messages after receiving the feedback information sent by the first functional module. In order to improve the sending and receiving efficiency of the messages and the sequential processing of the messages, the first functional module stores the received messages in a message queue, and then sequentially takes and processes the messages according to the sequence of storing the messages in the message queue. Meanwhile, after the first message is added into the message queue, feedback information is sent to the first message processing module, so that the first message processing module can continue to send the message to the first functional module. In this embodiment, the first functional module stores the first message through the message queue and transmits the feedback message after the storing is completed, instead of waiting for the first message to be processed or starting to be processed before the feedback message is transmitted. The method and the device avoid the blocking of the subsequent messages in the first message processing module, quicken the transmission efficiency of the messages, and reduce the working pressure of the first message processing module, so that the first message processing module only needs to call smaller registers or memory resources (such as only needs to reserve the memory space for storing 2-10 messages) when being built.
According to an aspect of the present application, there is provided an in-vehicle communication apparatus including:
a first functional module;
the first message processing module has a corresponding relation with the first functional module;
at least one second functional module, each of the second functional modules having a corresponding second message processing module;
wherein the first message processing module is configured to perform the following method:
receiving a first message sent by a second message processing module;
determining a message type of the first message;
and sending the first message to the first functional module under the condition that the message type is the target message type corresponding to the first functional module.
