Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering vehicle collision avoidance technology, specifically an intelligent collision avoidance system for engineering vehicles. Background Technology
[0002] At construction sites, such as road construction and building sites, there are often many workers moving and operating around construction vehicles. Due to the large size of construction vehicles and the existence of blind spots, drivers may find it difficult to fully observe the surrounding personnel. Onboard collision avoidance systems can monitor objects within a certain range around the vehicle in real time. When a worker is detected entering a danger zone, the system promptly alerts the driver, reminding them to take braking or evasive action, thereby effectively preventing collisions and ensuring the safety of the workers.
[0003] Reducing the risk of collisions with oncoming vehicles: Construction vehicles may collide with other vehicles while driving or working near the work area. This is especially true when construction is being carried out on busy roads, where oncoming vehicles may approach the construction vehicles due to unfamiliarity with the area or driver negligence. Onboard collision avoidance systems monitor the movement of surrounding vehicles and issue warning signals when a vehicle is detected approaching too closely, helping construction vehicle drivers react in advance and avoid collisions, thus protecting the safety of both parties.
[0004] However, there is currently no early warning and collision avoidance system that connects the blind spots of the work area and the driver in the cab of the engineering vehicle during operation. Furthermore, traditional collision avoidance systems simply involve adding cameras to the engineering vehicle. When the engineering vehicle is in operation or moving, it is not accurate to judge whether there are foreign objects entering the work area solely through the camera.
[0005] Therefore, an intelligent collision avoidance system for engineering vehicles is needed to address the above problems. Utility Model Content
[0006] The purpose of this invention is to provide an intelligent collision avoidance system for engineering vehicles. This invention uses cameras fixed at the four corners of the engineering vehicle to capture images of the work area at each corner. Then, ultrasonic radar at each corner inspects the work area for obstacles such as people. If a person or other obstacle is found, the control unit directly alerts the driver via a second speaker in the cab, and also activates a second audible warning via a light and sound device on the roof of the vehicle. Simultaneously, the monitoring images from the cameras at the four corners are transmitted to a display screen in the cab. The system displays information, allowing the driver to see any abnormalities in the work area immediately from a first-person perspective. This invention, combined with ultrasonic radar, more accurately determines whether foreign objects have entered the work area, avoiding the inaccuracies of traditional methods that rely solely on cameras. Furthermore, this invention connects information from outside the vehicle to inside the driver's cab, immediately alerting the driver. A single-line indicator light projects a red line around the construction vehicle during operation, marking the work area within the red line. This provides a clear warning and danger zone marker for passersby, minimizing damage from unexpected obstacles in the work area. This invention is highly practical.
[0007] This utility model is implemented as follows: An intelligent collision avoidance system for engineering vehicles includes protective shells fixedly mounted on both sides of the front and rear of the engineering vehicle. Cameras are fixedly mounted inside the protective shells, and ultrasonic radars are mounted adjacent to the cameras. First speakers are fixedly mounted on both sides of the front and rear of the engineering vehicle. A display screen is fixedly mounted in the driver's cab of the engineering vehicle, and a second speaker is fixedly mounted above the display screen in the driver's cab. A sound and light warning device is fixedly mounted on the top of the engineering vehicle. A control processing unit is fixedly mounted in the driver's cab. The first speakers, second speakers, and sound and light warning device are all connected to the output of the control processing unit, and the cameras and ultrasonic radars are all connected to the input of the control processing unit. The control processing unit is an Arm 7 type control processing unit and is also connected to a storage unit. Linear lights are fixedly mounted on all four sides of the roof of the engineering vehicle, and these lights are connected to the control processing unit. When the engineering vehicle is in operation, the linear lights project a red line around the vehicle, indicating the work area within the red line, providing a clear warning and danger zone marker for pedestrians.
[0008] The driver's cab of the engineering vehicle is also equipped with an external data transmission interface, which is a USB interface, connected to the storage unit. The USB interface allows connection to a memory device to retrieve the stored surveillance footage. Operation is simple, convenient, and quick.
[0009] Furthermore, a transparent baffle is fixedly installed in front of the camera in the protective shell. The transparent baffle can protect the camera and prevent it from being damaged by flying stones during operation.
[0010] Compared with existing technologies, the advantages of this invention are as follows: Cameras fixed at the four corners of the engineering vehicle capture images of the work area at each corner. Ultrasonic radars at the four corners then inspect for obstacles such as people. If a person or other obstacle is found, the control unit directly alerts the driver via a second speaker in the cab, and a second audible warning is issued via a light and sound device on the roof of the vehicle. Simultaneously, the monitoring images from the cameras at the four corners are transmitted to a display screen in the cab, allowing the driver to see any abnormalities in the work area immediately. This invention, combined with ultrasonic radar, more accurately determines whether foreign objects have entered the work area, avoiding the inaccuracies of traditional methods that rely solely on cameras. Furthermore, this invention connects information from outside the vehicle to inside the cab, immediately alerting the driver and minimizing damage from unexpected obstacles in the work area. This invention is highly practical. Attached Figure Description
