With the rapid development of social economy, a novel urban traffic mode can be that a monorail track is laid in a city, vehicles are conveyed through a conveying belt on the monorail track, and the problem of road congestion is solved. Therefore, a driving safety scheme suitable for the field of monorail track traffic needs to be provided. The scheme in the embodiment of the specification can be applied to the field of single-rail transportation.
The braking system can assist a driver to brake in time in practical application, can also automatically brake the vehicle, and can avoid the collision caused by too fast vehicle speed or untimely braking of the vehicle.
In practical application, many brake devices can only detect obstacles close to a vehicle, and when the obstacles are detected, the vehicle is close to the obstacles, and the vehicle cannot stop immediately due to inertia during braking, so that a certain braking distance exists, a certain time is required for stopping the vehicle, and the conventional brake devices do not have enough time for braking the vehicle, so that the vehicle cannot be braked in time.
Fig. 1 is an installation schematic diagram of an infrared distance measuring sensor assembly and a binocular camera in an automatic braking system provided in an embodiment of the present specification. As shown in figure 1, install infrared distance measuring sensor assembly 2 and binocular camera 3 on automobile body 1, infrared distance measuring sensor assembly 2 fixes at the windshield top of automobile body 1. Wherein the infrared ranging sensor assembly 2 may include a plurality of infrared ranging sensors.
Alternatively, the infrared distance measuring sensor assembly 2 may be installed at a top center position of a windshield of the vehicle body 1 so as to better detect a distance between the vehicle body 1 and an obstacle. Of course, in practical application, the infrared distance measuring sensor assembly 2 may be installed at any position of the windshield of the vehicle body 1, theoretically, as long as the driver's sight line is not shielded, and the corresponding regulations are met. The infrared distance measuring sensor assembly 2 may be mounted on any other position of the vehicle body 1 besides the windshield of the vehicle body 1.
In addition, it should be noted that, during the running process of the vehicle, there is a forward process, a backward process or a left-right turning process, so the infrared distance measuring sensor assembly 2 and the binocular camera 3 can be installed on both the front windshield and the rear windshield of the vehicle. The infrared distance measuring sensor component 2 can detect the distance between the obstacle and the vehicle body 1 in the vehicle running direction of the vehicle body in real time; therefore, infrared distance measuring sensor subassembly 2 can open when the vehicle starts, and two mesh cameras 3 can be used for gathering the ascending image information of automobile body 1 driving direction, and two mesh cameras 3 can have the shooting function, and the shooting function can be including function of shooing and video recording function. The binocular camera 3 may turn on a photographing function when the vehicle starts.
Optionally, the binocular camera 3 can also be in the infrared distance measuring sensor assembly 2 detects the barrier in the driving direction of the vehicle body 1 with when the distance between the vehicle body 1 is less than the preset distance, the shooting function is restarted, the barrier in the driving direction of the vehicle body 1 is shot, and image information is stored.
Fig. 2 is a schematic distance measurement diagram of an automatic braking system according to an embodiment of the present disclosure, and as shown in fig. 2, an infrared distance sensor assembly 2 is mounted on a front windshield of an automobile. The infrared distance measuring sensor assembly 2 may include a plurality of infrared distance measuring sensors having a pair of infrared signal emitting and receiving diodes, and the infrared distance measuring sensors emit a beam of infrared light to form a reflection process after irradiating an object, receive the signal after reflecting the sensor, and then receive data of time difference between emission and reception by using CCD image processing. The distance between the object and the object is calculated after the distance is processed by the signal processor.
Especially in the application scene that sleet weather or other environment are comparatively complicated, combine infrared range sensor and binocular camera, can calculate the distance that obtains the high accuracy when the distance between real-time supervision automobile body and the barrier to realize more effectual auxiliary brake or automatic braking.
The binocular camera 3 performs imaging by using a binocular distance measuring principle, and directly performs distance measurement on a front scene (a range where the image is shot) by calculating the parallax of two images without judging what type of obstacles appear in the front. Therefore, for any type of obstacles, necessary early warning or braking can be carried out according to the change of the distance information. The principle of the binocular camera 3 is similar to that of human eyes. Human eyes can perceive the distance of an object because the images of the same object presented by the two eyes are different, which is also called as parallax.
In the system, the infrared distance measuring sensor assembly 2 and the binocular camera 3 are arranged and interact with each other, so that the distance between the vehicle body 1 and the barrier in the driving process can be accurately determined, and the distance measuring and calculating accuracy is high.

Optionally, the infrared distance measuring sensor assembly 2 and the binocular camera 3 may be located at the same height. The distance between the vehicle body 1 and the obstacle can be measured and calculated more easily without performing distance conversion due to the positional relationship. For example: if the infrared distance measuring sensor assembly 2 is installed on a front windshield of the vehicle body 1 and the binocular camera 3 is installed beside a front lamp of the vehicle body 1, the distance between the front windshield and the front lamp needs to be calculated when the distance is measured, and therefore the efficiency of measurement is not improved.

an infrared distance measuring sensor assembly arranged on a windshield of the vehicle body acquires distance information; and a binocular camera mounted on a windshield of the vehicle body acquires image information. The infrared distance measurement sensor assembly sends the acquired distance information to the central processing unit; the binocular camera also sends the acquired image information to the central processing unit. And the central processing unit calculates the distance between the vehicle body and the barrier in the driving direction based on a binocular ranging principle according to the received distance information and the image information. Judging whether the distance reaches a preset braking distance or not; and if the distance reaches the preset braking distance, the central processing unit sends a braking instruction to drive the braking device to brake the vehicle body.
