Specific embodiment
In order to make the above objects, features, and advantages of the present application more apparent, with reference to the accompanying drawing and it is specific real
Applying mode, the present application will be further described in detail.
Referring to Fig.1, a kind of step flow chart of communication means embodiment one of the application, the communication means application are shown
In onboard system, the onboard system includes that multichannel communication component object and internal component object, the method specifically may be used
To include the following steps:
Step 101, multiple communication channels are established using the multichannel communication component object and server；
In the embodiment of the present application, multichannel communication component object is the component object for realizing multichannel communication, internal
Component object is the various assemblies object that onboard system includes, and may include control assembly object and Service Component object.Control
Component object can be the various Function for Automatic Pilot of realization for controlling vehicle (for example, automatic cruising function, automatic lane change function
Can, lane keep function, automatic parking function etc.) component object.Service Component object can be for realizing non-automatic
The component object of customer service (for example, online amusement function, voice call function) except driving.
Onboard system can establish multiple communicate with server using multichannel communication component object and lead in vehicle launch
Road.
Multiple communication channels can be the communication channel of different wireless communication agreement, such as the communication of 3G, 4G, 5G, WIFI
Channel, each communication channel can realize the two-way communication between multichannel communication component object and server.
In practice, if carried out data transmission only with single 4G connection, the unstability of 4G signal can be one
Biggish hidden danger.If the WIFI deployment of the full sections of road of unmanned vehicle is a huge construction using single WIFI connection
Problem.Therefore, the embodiment of the present application using and meanwhile support include 4G, WIFI connection multi-channel data communication means it is low to ensure
Delay, highly reliable data communication.
Step 102, the first data that the internal component object is sent are received using the multichannel communication component object,
And first data are sent to the server in the multiple communication channel respectively；
All internal component objects of onboard system require to carry out data transmission by multichannel communication component object,
The first data for needing to be sent to server are sent to multichannel communication component object by internal component object, by multichannel communication
Component object sends the first data in the multiple communication channels having built up respectively.That is multichannel communication component object exists
Multiple communication channels can all send the first data, though some communication channel disconnect, can also by other communication channels into
The transmission of row data, ensure that the reliable and low delay of data uplink.
Step 103, the service is received in the multiple communication channel respectively using the multichannel communication component object
The second data that device is sent, and second data are sent to the internal component object.
When server will send data to the internal component object of onboard system, respectively in multiple communication channels to multichannel
Communication component object sends the second data.That is multichannel communication component object can receive in multiple communication channels
Two data can also receive the second data in other communication channels, ensure that reception number even if some communication channel is disconnected
According to the reliability and low delay of downlink.
After multichannel communication component object receives the second data, determine the second data are which internal component be sent to
Object is then forwarded to corresponding internal component object.
In the embodiment of the present application, multiple communication channels, multi-pass are established using multichannel communication component object and server
The first data that road communication component object can send internal component object are sent to server by multiple communication channels；

Two-way communication between server.
Specifically, can be using multichannel communication component object according to message queue telemetering transport protocol MQTT (Message
Queuing Telemetry Transport), the communication channel of multiple communication protocols is established with server.
MQTT is the messaging protocol based on publish/subscribe normal form, work on TCP/IP protocol suite, be for hardware performance it is low
Under remote equipment and Network status it is bad in the case where and the publish/subscribe type messaging protocol that designs.
Primary MQTT is not support multichannel communication, by modifying to MQTT in the embodiment of the present application, so that
MQTT can support multichannel communication, can reduce development cost based on the modification to MQTT, shorten the development cycle.Certainly in reality
In border, it can also not limited this by the self-built communication protocol for supporting channel transmission, the application.
Step 202, the first data that the internal component object is sent are received using the multichannel communication component object,
And first data are sent to the server in the multiple communication channel respectively；
In the embodiment of the present application, internal component object has internal unity interface object, and internal unity interface object is
Interface object for uniformly being sent and received with multiple internal component objects.
The step that the first data that the internal component object is sent are received using the multichannel communication component object
It suddenly may include: that the first data that the internal component object is sent are received using the internal unity interface object.
Step 203, the service is received in the multiple communication channel respectively using the multichannel communication component object
The second data that device is sent；
Step 204, it is filtered using the multichannel communication component object in received second number of the multiple communication channel
Repeated data in；
Due to all having received the second data in multiple communication channels, multichannel communication component object can obtain duplicate
Second data, data redundancy, multichannel communication component object can carry out at heavy filtration the data received in order to prevent
Reason, to remove repeated data.
Step 205, second data are sent to the internal component object.
Described the step of second data are sent to the internal component object may include: using the internal system
Second data are sent to the internal component object by one interface object.
In the embodiment of the present application, multiple communication channels, multi-pass are established using multichannel communication component object and server
The first data that road communication component object can send internal component object are sent to server by multiple communication channels；
The second data that server is sent are sent to multichannel communication component object in multiple communication channels, by multichannel communication component pair
As being sent to corresponding internal component object, the low delay, highly reliable of communication ensure that.
In order to make those skilled in the art can better understand that the embodiment of the present application, below by an example to this Shen
Please embodiment be illustrated:
It is illustrated in figure 3 the schematic diagram of onboard system and server communication in the embodiment of the present application.
Onboard system may include multichannel communication component object and multiple internal component objects, for example, Service Component pair
As, control assembly object, the multichannel communication component object of onboard system has internal unity interface object, and server has more
Tunneling traffic component object.
