Embodiment 1

[0025] figure 1 It is a flow chart of the data acquisition method for sensors provided by Embodiment 1 of the present invention. This embodiment can be applied to the situation of obtaining data of each sensor on an unmanned vehicle. This method can be executed by an event distributor, and the event distribution The controller can be implemented in the form of software and / or hardware, and can be configured in an electronic device, which can be configured on a vehicle, such as an unmanned vehicle with control and computing capabilities. Such as figure 1 As shown, the method specifically includes:

[0026] S110. The pre-created sensor-based event distributor monitors the data preparation status of all sensors in real time.

[0027] For highly automated unmanned vehicles, in order to ensure the normal and safe driving of unmanned vehicles, various sensors are installed on the body of the unmanned vehicle, such as lidar, millimeter wave radar, camera, ultrasonic radar, infrared...

Embodiment 2

[0035] figure 2 It is a flow chart of a data acquisition method for a sensor provided in Embodiment 2 of the present invention. This embodiment is further optimized on the basis of the foregoing embodiments. Such as figure 2 As shown, the method includes:

[0036] S210. A pre-created sensor-based event distributor monitors the data preparation status of all sensors in real time.

[0037] S220. When it is detected that the data of the target sensor is ready, acquire the data acquisition method corresponding to the target sensor, wherein the data acquisition method is pre-registered by the event distributor.

[0038] In the embodiment of the present invention, different sensors on the unmanned vehicle have different data acquisition methods, that is, each sensor corresponds to a data acquisition method for acquiring data on the sensor, wherein the data acquisition method includes data Transmission protocol, process, and exception handling mechanism, etc., for example, obtai...

Embodiment 3

[0045] image 3 is a schematic diagram of the structure of the event distributor provided by Embodiment 3 of the present invention, such as image 3 shown, including:

[0046] Monitoring module 310, for real-time monitoring of the data preparation status of all sensors;

[0047] The task creation module 320 is used to create a data reading task for the target sensor when monitoring that the data of the target sensor is ready;

[0048] The scheduling execution module 330 is configured to call a system scheduler to schedule and execute the data reading task.

[0049] In the embodiment of the present invention, when the monitoring module 310 monitors the sensor to obtain data, when the data of the target sensor is detected to be ready, the task creation module 320 creates a task thread for obtaining data for the target sensor, and hands it over to the scheduling execution module The 330 performs overall scheduling and fetches data, thereby reducing the number of threads and sa...

Abstract

An embodiment of the present invention discloses a data acquisition method for a sensor, an event distributor, a device, a medium and an unmanned vehicle, wherein, the method comprises the following steps: a sensor-based event distributor is created in advance to listen to the data preparation state of all sensors in real time; a data reading task for the target sensor is created when the data ofthe target sensor is sniffed out is ready; a system schedule is invoked to schedule execution of that data read task. An embodiment of the present invention listens to the data readiness of the sensorthrough an event dispatcher which is a thread, when the data of the target sensor is ready, the task thread for fetching data is created for the target sensor, and the task thread is handed to the scheduler for overall scheduling, so as to realize data fetching, thereby reducing the number of threads and saving system resources as a whole.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of unmanned vehicles, and in particular, relate to a data acquisition method for sensors, an event distributor, equipment, media, and unmanned vehicles. Background technique [0002] With the development of science and technology, more and more tools in life tend to be intelligent, especially the research of driverless cars, which will provide great convenience for people's life in the future. In the research of unmanned vehicles, in order to ensure the normal driving of unmanned vehicles, it is necessary to obtain the data collected by the sensors on the unmanned vehicles in real time. [0003] In the prior art, the main driving mode of the sensors in the unmanned vehicle is that each sensor corresponds to a thread for data scanning, so as to obtain data from the sensors. However, this method of data acquisition has certain deficiencies. For example, for the thread that is scanning da...
