Problems solved by technology

[0006] In the existing technology, the sensing base station sends or forwards messages carrying various types of information in the same way, which makes it possible that emergency messages cannot reach the recipients in time or effectively (including traffic participants on the road, etc.) ), so that it is impossible to make corresponding driving decisions in time, leading to accidents

Embodiment 1

[0061] The first embodiment firstly provides a sensing base station in an intelligent transportation system, see figure 2 , the sensing base station may specifically include:

[0062] The message classification module 201 is configured to obtain at least one message to be sent, determine whether it belongs to the first type of message or the second type of message according to the target field included in the message, add the first type of message to the first message queue, and trigger For sending the first type of message, adding the second type of message to the second message queue;

[0063] The time division multiplexing TDMA control module 202 is used to obtain the timing signal and the time slot resource information allocated for the associated sensing base station, and when the time slot arrives, read the second type of message from the second message queue and trigger the pair The sending of the second type of message.

[0064] Wherein, the message to be sent may b...

Embodiment 2

[0111] The second embodiment corresponds to the first embodiment, and provides a method for controlling message transmission in a sensing base station, see Figure 4 , the method may specifically include:

[0112] S401: Obtain at least one message to be sent, and determine whether it belongs to the first type of message or the second type of message according to the target field included in the message;

[0113] S402: Add the first type of message to the first message queue, and trigger sending of the first type of message;

[0114] S403: Add the second type of message to the second message queue;

[0115] S404: Obtain the timing signal and the time slot resource information allocated for the associated sensing base station, and when the time slot arrives, read the second type of message from the second message queue and trigger the sending of the second type of message .

[0116] During specific implementation, if the first type of message is generated when the sensing bas...

Embodiment 3

[0119] The third embodiment provides a method for generating messages in a road traffic environment from the perspective of message producers, see Figure 5 , the method may specifically include:

[0120] S501: The sensing base station obtains information in the road traffic environment;

[0121] S502: Determine the urgency of the information according to the information type, function and / or scene information of the information;

[0122] S503: Write the urgency information into a corresponding field in a preset message structure, and generate a message, so as to determine a message sending policy according to the urgency.

[0123] During specific implementation, the road traffic environment can be sensed by triggering the sensor system, and the information in the road traffic environment can be obtained.

[0124] At this time, in the process of triggering the sensor system, the trigger timing may also be determined according to the time slot resource allocated to the associ...

Abstract

The embodiment of the invention discloses a sensing base station in a road traffic environment and a message sending control method and device of the base station. The sensing base station comprises:a message classification module which is used for obtaining at least one message to be sent, determining whether the message belongs to a first type of messages or a second type of messages accordingto a target field included in the message, adding the first type of messages into a first message queue, triggering sending of the first type of messages, and adding the second type of messages into asecond message queue; and a time division multiplexing TDMA control module which is used for obtaining a time service signal and time slot resource information allocated to the associated sensing base station, and triggering the sending of the second type of messages after reading the second type of messages from the second message queue when a time slot arrives. According to the embodiment of the invention, various types of messages can be sent to a receiver more timely and reliably.

Description

technical field [0001] The present application relates to the technical field of vehicle-road coordination, in particular to a sensing base station in a road traffic environment and a method and device for controlling message transmission thereof. Background technique [0002] In the fields of autonomous driving and intelligent transportation, highly intelligent autonomous vehicles can effectively perceive their surrounding environment, obtain information such as the type, position, orientation, size, and speed of nearby targets, and make reasonable decisions based on their own driving status. The driving decision-making of the vehicle is completed to complete the work of driving the vehicle, thereby replacing manual driving labor and realizing a highly automated driving process. [0003] At present, there are two main types of autonomous driving perception systems: vehicle-mounted sensor network perception and vehicle-road collaborative perception. In the way of on-board s...
