Example Embodiment

[0024] Example one

[0025] figure 1 This is a flowchart of a method for acquiring sensor data provided in the first embodiment of the present invention. This embodiment is applicable to the situation of acquiring data from various sensors on an unmanned vehicle. The method can be executed by an event distributor. The device can be implemented in 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 unmanned vehicles, such as lidar, millimeter wave radar, cameras, ultrasonic radar, infrared sensors, and GPS antenn...

[0034] Example two

[0035] figure 2 This is a flowchart of a method for acquiring sensor data provided in the second embodiment of the present invention. This embodiment is further optimized on the basis of the foregoing embodiment. Such as figure 2 As shown, the method includes:

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

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

[0038] In the embodiment of the present invention, different sensors on the unmanned vehicle obtain data in different ways, that is, each sensor corresponds to a data obtaining method for obtaining data from the sensor, wherein the data obtaining method includes data Transmission protocol, process and exception handling mechanism, etc., f...

Example Embodiment

[0044] Example three

[0045] image 3 It is a schematic diagram of the structure of the event distributor provided in the third embodiment of the present invention, such as image 3 Shown, including:

[0046] The monitoring module 310 is used to monitor the data preparation status of all sensors in real time;

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

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

[0049] In the embodiment of the present invention, when the monitoring module 310 monitors the sensor to acquire data, when the monitoring target sensor's data is ready, the task creation module 320 creates a task thread for the target sensor to retrieve the data, and hands it to the scheduling execution module 330 performs overall scheduling to obtain data, thereby reducing the numb...

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...
