Description

A collision avoidance system for highway maintenance equipment vehicles Technical Field

[0001] This invention relates to the field of collision avoidance technology, and in particular to a collision avoidance system for highway maintenance equipment vehicles. Background Technology

[0002] In the maintenance and repair of urban expressways and highways, some projects require temporary road closures, such as pothole repair, ancillary facility repair, and expansion joint maintenance. Other maintenance projects require mobile operations, such as mechanical sweeping, litter collection, and landscaping watering. Therefore, the main hazard for these operations is vehicle collisions. Highways and elevated roads frequently experience tragic accidents where civilian vehicles rear-end construction vehicles, resulting in the deaths of workers or drivers.

[0003] Chinese Patent Publication No. CN202221241192.1 discloses a safety buffer device for highway maintenance work areas, comprising a first protective frame and a second protective frame. Multiple airbags are installed inside both the first and second protective frames, and lifting supports are fixedly connected to corresponding sides at the bottom of each frame. This device primarily aims to prevent collisions through buffering. However, due to the high speeds on highways, the buffer structure cannot completely prevent accidents. Therefore, it is necessary to design a device that can monitor the status of road vehicles in real time to avoid affecting the safety of highway maintenance equipment vehicles. Summary of the Invention

[0004] The purpose of this invention is to provide a collision avoidance system for highway maintenance equipment vehicles, which solves the technical problem that existing highway maintenance equipment vehicles are prone to traffic accidents when performing maintenance on expressways.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A collision avoidance system for highway maintenance equipment vehicles includes an on-board unit, a vehicle position detection unit, and a highway maintenance equipment vehicle unit. The on-board unit is wirelessly connected to the vehicle position detection unit, and the vehicle position detection unit is also wirelessly connected to the highway maintenance equipment vehicle unit. The on-board unit is used to send addressing signals in real time for the vehicle position detection unit to detect the vehicle. Simultaneously, based on the alarm information received from the vehicle position detection unit, it promptly avoids the lane where the highway maintenance equipment vehicle is located. The vehicle position detection unit is used to detect the lane position and vehicle status information of vehicles on the road within a fixed range in real time. When a vehicle on the road is about to collide with the highway maintenance equipment vehicle or a warning cone placed in front, a warning message is sent to the highway maintenance equipment vehicle unit. At the same time, the vehicle data of the detected road section is transmitted to the highway maintenance equipment vehicle unit in real time. When the highway maintenance equipment vehicle unit receives a stop-work avoidance warning, it issues a warning to notify the staff to stop work and take actions to avoid collision. In addition, the highway maintenance equipment vehicle unit can normally view the vehicle operation status information behind the maintenance section and adjust the maintenance work in a timely manner to avoid affecting the normal traffic flow.

[0007] Furthermore, the vehicle-mounted terminal is installed on the vehicle on the road. The vehicle-mounted terminal includes a vehicle-mounted location signal transmitting module, a vehicle-mounted wireless transmitting and receiving module, a vehicle-mounted controller module, and a vehicle-mounted alarm prompting module. The vehicle-mounted location signal transmitting module, the vehicle-mounted wireless transmitting and receiving module, and the vehicle-mounted alarm prompting module are all connected to the vehicle-mounted controller module. The vehicle-mounted location signal transmitting module is used to send location signals in real time. When there is an approaching vehicle position detection terminal within the signal strength range, the approaching vehicle position detection terminal receives the location signal. At the same time, based on the direction of the vehicle, the vehicle-mounted wireless transmitting and receiving module is used to communicate with the approaching vehicle position detection terminal. The vehicle-mounted controller module is used to receive the signals transmitted from the approaching vehicle position detection terminal, process them, and transmit them to the vehicle-mounted alarm prompting module. The vehicle-mounted alarm prompting module is used to remind the driver to avoid the vehicle where the maintenance equipment vehicle is located.

[0008] Furthermore, the vehicle-mounted positioning signal transmitting module transmits a signal outward in a 360-degree arc from the vehicle. The transmitted signal carries the location information of the starting point and the device marking information. After receiving the signal, the approaching vehicle position detection end sends back the transmitted signal, and the feedback signal contains the location point of the approaching vehicle position detection end. Then, a vector is formed between the two points. After passing through several approaching vehicle position detection ends, multiple vectors are obtained. The specific location of the vehicle can be obtained based on the angle between the vectors. The approaching vehicle position detection end then requests communication with the vehicle-mounted wireless transmitting and receiving module based on the device marking information.

[0009] Furthermore, the vehicle-mounted terminal also includes an on-board automatic deceleration control module, a vehicle status data lookup and transmission module, and a data display module. All three modules are connected to the on-board controller module. The vehicle status data lookup and transmission module, after communicating with the approaching vehicle position detection terminal, is used by the on-board controller module to notify the vehicle status data of the vehicle's operating status and transmit it to the on-board controller module. Based on the position of the nearest approaching vehicle position detection terminal, the on-board controller module issues a control command to the on-board automatic deceleration control module to control the vehicle's automatic deceleration. The data display module displays the lane occupied by the maintenance equipment vehicle and the specific distance.

[0010] Furthermore, the vehicle location detection terminal includes several road vehicle positioning and search communication devices. These devices are installed on the traffic cones used for lane separation to detect the distance between the vehicle and the separation point and notify the driver to change lanes in time.

[0011] Furthermore, the road vehicle positioning and search communication device includes a road vehicle positioning and search module, a detection wireless transceiver module, and a collapse detection module. Both the road vehicle positioning and search module and the collapse detection module are connected to the detection wireless transceiver module. The road vehicle positioning and search module is used to detect the location of vehicles within a set range and transmit the vehicle marking information of the detected vehicles to the detection wireless transceiver module. The detection wireless transceiver module communicates with the corresponding vehicles based on the vehicle marking information. The collapse detection module is used to detect whether the cones have collapsed. If a collapse is detected, it promptly notifies the personnel at the road maintenance equipment vehicle end to handle the situation.

[0012] Furthermore, the highway maintenance equipment vehicle terminal includes a maintenance equipment vehicle information receiving module, a road vehicle status information viewing module, a maintenance equipment vehicle controller module, and an audible and visual alarm evacuation module. When the lane occupied by the maintenance equipment vehicle exceeds the set speed and safe distance, the road vehicle positioning and communication device sends avoidance information to the maintenance equipment vehicle information receiving module. The maintenance equipment vehicle information receiving module then transmits this information to the audible and visual alarm evacuation module to trigger an audible and visual alarm, prompting staff to take cover. Simultaneously, the road vehicle positioning and communication device sends real-time road traffic flow data from the backend to the maintenance equipment vehicle information receiving module. The road vehicle status information viewing module monitors the traffic flow data. When the traffic flow exceeds a certain value, indicating a traffic jam or impending traffic jam, staff promptly evacuate the maintenance equipment vehicle and related traffic cones to restore traffic flow.

[0013] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0014] This invention detects oncoming vehicles in real time and promptly notifies them to change lanes or automatically slow down, effectively preventing collisions with traffic cones or road maintenance equipment vehicles and reducing road accidents. Simultaneously, when a vehicle fails to yield in time, the invention notifies the personnel on the road maintenance equipment vehicle to make evasive maneuvers, effectively preventing personal injury from accidents. Furthermore, it monitors traffic flow information in real time and makes timely adjustments when congestion occurs or is about to occur, preventing road maintenance equipment vehicles from affecting road traffic.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the invention, and these aspects of the invention can be implemented even without these specific details.

[0020] As shown in Figure 1, a collision avoidance system for highway maintenance equipment vehicles includes an on-board unit, a vehicle position detection unit, and a highway maintenance equipment vehicle unit. The on-board unit is wirelessly connected to the vehicle position detection unit, and the vehicle position detection unit is also wirelessly connected to the highway maintenance equipment vehicle unit. The on-board unit is used to send addressing signals in real time for the vehicle position detection unit to detect the vehicle. Simultaneously, based on the alarm information received from the vehicle position detection unit, it promptly avoids the lane where the highway maintenance equipment vehicle is located. The vehicle position detection unit is used to detect the lane position and vehicle status information of vehicles on the road within a fixed range in real time. When a vehicle on the road is about to collide with the highway maintenance equipment vehicle or a warning cone placed in front, a warning message is sent to the highway maintenance equipment vehicle unit. At the same time, the vehicle data of the detected road section is transmitted to the highway maintenance equipment vehicle unit in real time. When the highway maintenance equipment vehicle unit receives a stop-work avoidance warning, it issues a warning to notify the staff to stop work and take actions to avoid collision. Meanwhile, the highway maintenance equipment vehicle unit can normally view the vehicle operation status information behind the maintenance section and adjust the maintenance work in a timely manner to avoid affecting the normal traffic flow.

[0021] The vehicle-mounted terminal is installed on the moving vehicle, the oncoming vehicle position detection terminal is installed on the cones, and the highway maintenance equipment vehicle terminal is installed on the highway maintenance equipment vehicle. By detecting and notifying in advance, traffic accidents can be avoided.

[0022] In this embodiment of the invention, as shown in Figure 2, the vehicle-mounted terminal is installed on a vehicle traveling on a road. The vehicle-mounted terminal includes a vehicle-mounted location signal transmitting module, a vehicle-mounted wireless transmitting and receiving module, a vehicle-mounted controller module, and a vehicle-mounted alarm prompting module. The vehicle-mounted location signal transmitting module, the vehicle-mounted wireless transmitting and receiving module, and the vehicle-mounted alarm prompting module are all connected to the vehicle-mounted controller module. The vehicle-mounted location signal transmitting module is used to transmit location signals in real time. When there is an approaching vehicle location detection terminal within the signal strength range, the approaching vehicle location detection terminal receives the location signal. At the same time, based on the determined direction of the vehicle, the vehicle-mounted wireless transmitting and receiving module is used to communicate with the approaching vehicle location detection terminal. The vehicle-mounted controller module is used to receive the signal transmitted from the approaching vehicle location detection terminal, process it, and transmit it to the vehicle-mounted alarm prompting module. The vehicle-mounted alarm prompting module is used to remind the driver to avoid the vehicle where the maintenance equipment vehicle is located.

[0023] The vehicle alarm module emits sound and flashing lights to notify the driver to brake and slow down or change lanes in time to avoid traffic accidents caused by excessive speed and failure to brake within braking distance. By using a vector method to find the signal, the direction can be determined, and then the intersection point can be obtained after multiple vectors intersect, which is the vehicle's position.

[0024] The vehicle-mounted positioning signal transmitting module transmits a signal outward in a 360-degree arc from the vehicle. The transmitted signal carries the location information of the starting point and the device marking information. After receiving the signal, the approaching vehicle position detection end sends back the transmitted signal, and the feedback signal contains the location point of the approaching vehicle position detection end. Then, a vector is formed between the two points. After passing through several approaching vehicle position detection ends, multiple vectors are obtained. The exact location of the vehicle can be obtained based on the angle between the vectors. The approaching vehicle position detection end then requests communication with the vehicle-mounted wireless transmitting and receiving module based on the device marking information. The vehicle-mounted terminal also includes an on-board automatic deceleration control module, a vehicle status data lookup and transmission module, and a data display module. All three modules are connected to the on-board controller module. The vehicle status data lookup and transmission module, after communicating with the approaching vehicle position detection terminal, is used by the on-board controller module to notify the vehicle's operating status data and transmit it to the on-board controller module. Based on the position of the nearest approaching vehicle position detection terminal, the on-board controller module issues control commands to the on-board automatic deceleration control module to control the vehicle's automatic deceleration. The data display module displays the lane occupied by the maintenance equipment vehicle and the specific distance.

[0025] In this embodiment of the invention, as shown in Figure 3, the vehicle location detection terminal includes several road vehicle positioning and communication devices. These devices are installed on the traffic cones used for lane separation and are used to detect the distance between vehicles and the separation points, notifying drivers to change lanes in a timely manner. Each road vehicle positioning and communication device includes a road vehicle positioning module, a detection wireless transceiver module, and a rollover detection module. Both the road vehicle positioning module and the rollover detection module are connected to the detection wireless transceiver module. The road vehicle positioning module detects the location of vehicles within a set range and transmits the vehicle marking information of the detected vehicles to the detection wireless transceiver module. The detection wireless transceiver module communicates with the corresponding vehicles based on the vehicle marking information. The rollover detection module detects whether the traffic cones have rolled over; if rollover is detected, it promptly notifies the personnel at the road maintenance equipment vehicle end for handling.

[0026] Several road vehicle positioning and search communication devices communicate with each other. When detecting the position of a vehicle, they obtain the vehicle's position information by transmitting and receiving information vectors from each other and then using the intersection points of the information vectors.

[0027] In this embodiment of the invention, as shown in Figure 4, the highway maintenance equipment vehicle terminal includes a maintenance equipment vehicle information receiving module, a road vehicle status information viewing module, a maintenance equipment vehicle controller module, and an audible and visual alarm evacuation module. When the lane occupied by the maintenance equipment vehicle exceeds the set speed and safe distance, the road vehicle positioning and search communication device sends avoidance information to the maintenance equipment vehicle information receiving module. The maintenance equipment vehicle information receiving module then transmits this information to the audible and visual alarm evacuation module to trigger an audible and visual alarm, prompting staff to evacuate. Simultaneously, the road vehicle positioning and search communication device sends real-time road traffic flow data from the backend to the maintenance equipment vehicle information receiving module. The road vehicle status information viewing module views the traffic flow data. When the traffic flow exceeds a certain value, indicating a traffic jam or impending traffic jam, staff promptly evacuate the maintenance equipment vehicle and related traffic cones to restore traffic flow.

[0028] The road vehicle status information viewing module is mainly used to check whether there is traffic congestion on the road. When traffic congestion occurs or is about to occur, it promptly notifies construction personnel to remove relevant road cones to avoid traffic jams.

[0029] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
