Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent driving simulation training and learning equipment, and specifically relates to a vehicle networking test training and learning device. Background Art

[0002] The Internet of Vehicles refers to a huge interactive network composed of information such as vehicle location, speed and route. Through GPS, RFID, sensors, camera image processing and other devices, vehicles can collect their own environment and status information; through Internet technology, all vehicles can transmit their various information to the central processor; through computer technology, the information of these large vehicles can be analyzed and processed, so as to calculate the best routes for different vehicles, report road conditions in a timely manner and arrange traffic light cycles. Therefore, vehicle network technology is crucial to vehicle automatic assisted driving. The environmental perception system of the automatic assisted driving system provides information such as the relative distance and relative speed of surrounding targets, pedestrians and other traffic participants. Vehicle intelligent driving test logic such as Figure 1 As shown, in intelligent driving tests, sensors are needed to collect information about the vehicle and its surrounding environment.

[0003] At present, the more common method is to install sensors on the vehicle body to obtain information about the environment around the vehicle, obstacle detection, interactive testing, precision parking, V2X, and storage location identification. Affected by the constraints of scenes and sites, the effective detection distance and detection range of vehicles are quite different, and the scenes of storage location form, direction, angle, etc. are not uniform. Taking the common straight-line storage with conventional storage array as an example, for every degree of error increase, the detection center point is offset by 0.85 meters from the actual target point. At the same time, there is a corresponding loss in the effective detection area, and the recognition is incomplete. Therefore, it is necessary to train and learn the sensors so that their positions in the three-coordinate space meet the use requirements, ensure the normal operation of the sensors, and then ensure the accuracy of the vehicles in various scenes. There are two problems in the existing technology: First, the vehicle has a large error in testing unfamiliar scenes under the recognition of the sensor, and the test personnel need to repeatedly perform stress testing, adjust the data of the single vehicle, and position and install the sensors, resulting in low test efficiency, poor consistency, and uncontrollable quality; second, large-scale automation equipment needs to be customized for mass-produced vehicles, and the equipment purchase cost, use and maintenance cost are huge, and the equipment requires a large area. Utility Model Content

[0004] The purpose of the utility model is to address the defects of the prior art and to propose a portable and movable vehicle networking test training and learning device that has low requirements on site size and flatness and can be installed relatively quickly and efficiently.

[0005] In order to achieve the above objectives, the utility model provides a vehicle networking test training and learning device, including an intelligent driving sensor and a bracket for installing the intelligent driving sensor, the bracket including at least one height-adjustable bracket unit, the bracket unit is arranged at a monitoring position of the vehicle networking test, and the intelligent driving sensor is connected to a host computer through a controller.

[0006] The device of the utility model provides training and learning equipment for intelligent driving sensor training and learning. The intelligent driving sensors include millimeter wave radars, laser radars, cameras, etc. The intelligent driving sensors are connected to the host computer through data transmission to facilitate the detection of the position of the intelligent driving sensors. Therefore, the device of the utility model can detect and adjust the installation position of the sensor in space according to actual test requirements to meet the needs of training and learning for different types of vehicles.

[0007] The utility model further adopts the following technical solutions:

[0012] In the above structure, the height adjustment tube and the positioning limit tube can be used separately, or they can be connected by threads to adjust the height of the tube, thereby realizing the adjustment of different installation heights of the intelligent driving sensor. When the height adjustment tube and the positioning limit tube are used separately, the fixed height of the tube is the height of the height adjustment tube or the positioning limit tube. When the tube is threadedly connected, the height of the tube is the sum of the threaded connection tubes.

[0013] Preferably, the pipe fitting includes a first height adjustment tube, a positioning and limiting tube and a second height adjustment tube, the upper end of the first height adjustment tube is threadedly connected to the lower end protrusion of the mounting platform, and the lower end is threadedly connected to the upper end of the positioning and limiting tube, the lower end of the positioning and limiting tube is threadedly connected to the upper end of the second height adjustment tube, and the lower end of the second height adjustment tube is threadedly connected to the upper end connecting rod of the counterweight base.

[0015] By adopting the above structure, the height of the pipe fitting can be fine-tuned by adjusting the screwing depth of the thread.

[0016] Preferably, the counterweight base comprises a bottom plate and a connecting rod, the connecting rod is mounted on the bottom plate, and the upper end of the connecting rod is connected to a pipe fitting.

[0019] The above-mentioned installation platform is used to install intelligent driving sensors and other equipment. It can install a variety of sensors and is easy to install and use.

[0020] The bracket of the utility model adopts distributed assembly. The height of the bracket is adjusted by selecting the number of height adjustment tubes and the depth of the threaded insertion. The width of the bracket is adjusted by the number, position and distance between the bracket units, thereby realizing the installation and testing of different intelligent driving sensors.

[0021] The utility model adopts distributed assembly, which can adaptively adjust the height and width of the intelligent driving sensor mounting bracket. Different intelligent driving sensors can be quickly limited and fixed through the bracket. At the same time, the intelligent driving sensor can move with the bracket, which reduces the workload and improves the test efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
