[0027] Exemplary embodiments of the present application will be described in greater detail below with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein.

[0028] Figure 1 A flowchart of a first embodiment of a method for improving slope driving safety provided by the present application is shown, which is executed by a device for improving slope driving safety. As shown in Figure 1 The method comprises the following steps:

[0029] Step 110: Collecting forward vehicle image information at the slope.

[0030] In this embodiment, the ramp is bidirectional, and the ramp is specifically an upward ramp. Vehicles driving from the top of the ramp to the bottom of the ramp are forward vehicles, and vehicles driving from the bottom of the ramp to the top of the ramp are reverse vehicles. Specifically, image acquisition devices are arranged at the ramp to acquire image information of forward vehicles at the ramp. The image acquisition devices are uniformly arranged on both sides and at the top of the ramp. The image acquisition devices make the acquired image information of the forward vehicles more accurate. The uniformly arranged image acquisition devices can also be used as reference objects to assist in judging the driving speed and driving track of the corresponding forward vehicle of the reverse vehicle. The image acquisition device includes a camera and a vertical rod. The camera is fixed on the vertical rod. The camera can be an AC-HX-P13G4C1 camera of Nanfang Anchuang.

[0031] Step 120: receiving reverse vehicle deviation information of the reverse vehicle.

[0032] When the forward vehicle and the reverse vehicle move towards each other, and the reverse vehicle collects the deviation of the driving track of the forward vehicle, which threatens the reverse vehicle, the reverse vehicle generates and sends corresponding reverse vehicle deviation information. The reverse vehicle deviation information specifically includes the license plate number, deviation direction, and current time of the forward vehicle.

[0033] Step 130: judging whether the corresponding forward vehicle of the reverse vehicle deviates according to the forward vehicle image information and the reverse vehicle deviation information. If the corresponding forward vehicle deviates, safety information is generated and sent to the forward vehicle.

[0034] The step of judging whether the corresponding forward vehicle of the reverse vehicle deviates according to the forward vehicle image information and the reverse vehicle deviation information specifically includes: retrieving the forward vehicle image information of the corresponding forward vehicle of the reverse vehicle according to the reverse vehicle deviation information, obtaining the driving speed and driving track of the corresponding forward vehicle according to the forward vehicle image information, and then judging whether the corresponding forward vehicle deviates according to the driving speed and driving track of the corresponding forward vehicle.

[0035] According to the collected forward vehicle image information, it is verified whether the information sent by the reverse vehicle is real, the accuracy of the information is ensured, and subsequent work is avoided.

[0036] The safety information of the forward vehicle specifically includes the license plate number, speed limit, and driving direction.

[0037] When the driving speed of the forward vehicle is greater than the first preset speed, vehicle safety information is generated and sent to the reverse vehicle. If the driving speed of the forward vehicle is relatively fast, the forward vehicle may cross the boundary and still threaten the reverse vehicle. At this time, the reverse vehicle needs to move away from the boundary in the middle of the road to reduce the occurrence of collisions. The reverse vehicle safety information specifically includes safety direction information.

[0038] When the driving speed of the forward vehicle is greater than the second preset speed, vehicle braking instruction information is generated and sent to the forward vehicle. In the process of descending, the forward vehicle may lose control, and the forward vehicle braking instruction information is used to assist vehicle braking at this critical moment. Specifically, when the driving speed of the normal vehicle exceeds the second preset speed, the forward vehicle braking instruction information is generated and sent. The first preset speed and the second preset speed are specifically set according to the speed limit on the slope and historical traffic accidents and the like.

[0039] The method further comprises emitting a preset frequency flashing prompt light to the deviated forward vehicle. Through the light prompt, the driver is quickly reminded, so that the driver timely controls the vehicle. The prompt light is specifically emitted to the front of the vehicle, and the prompt light is specifically red.

[0040] The method further comprises sending a vehicle distance maintaining information to a rear vehicle deviated from the forward vehicle. When the forward vehicle controls the vehicle speed, the distance between the forward vehicle and the rear vehicle is reduced, and it is difficult to timely control the distance on the slope. The vehicle distance maintaining information is sent, so that the rear vehicle timely controls the vehicle speed and maintains the distance, thereby reducing the occurrence of collision accidents.

[0041] The embodiment can timely exchange information of the forward and reverse vehicles by collecting, receiving, processing and sending information at the slope, performing relay processing and forwarding, so that the driver can timely obtain information on the other relative slope surface of the slope, and timely transmit the information to the driver, thereby ensuring the safety of the vehicle and avoiding information transmission delay of the network equipment. The reverse vehicle deviation information obtained by receiving the reverse vehicle is used to obtain corresponding reverse vehicle image information, and it is judged whether the corresponding reverse vehicle is truly deviated, so that the accuracy of the information is ensured. The safety information of the forward vehicle is sent, so that the corresponding forward vehicle is timely informed to control the vehicle speed and the driving track, thereby effectively avoiding the traffic accidents caused by the visual blind area. Through the light prompt, the driver is quickly reminded, so that the driver timely controls the vehicle. The vehicle distance maintaining information is sent, so that the rear vehicle timely controls the vehicle speed and maintains the distance, thereby reducing the occurrence of collision accidents.

[0042] Figure 2 A flowchart of a second embodiment of a method for improving slope driving safety is shown, and the method is executed by a device for improving slope driving safety. As shown in the figure, the method comprises the following steps: Figure 2

[0043] Step 110: Collecting forward vehicle image information at the slope.

[0044] ​In this embodiment, the ramp is bidirectional, and the ramp is specifically an upward ramp. Vehicles driving from the top of the ramp to the bottom of the ramp are forward vehicles, and vehicles driving from the bottom of the ramp to the top of the ramp are reverse vehicles. Specifically, image acquisition devices are arranged at the ramp to acquire image information of forward vehicles at the ramp. The image acquisition devices are uniformly arranged on both sides and at the top of the ramp. The image acquisition devices make the acquired image information of forward vehicles more accurate. The uniformly arranged image acquisition devices can also be used as reference objects to assist in judging the driving speed and driving trajectory of the corresponding forward vehicle of the reverse vehicle. The image acquisition device includes a camera and a vertical rod. The camera is fixed on the vertical rod. The camera can be an AC-HX-P13G4C1 camera of Nanfang Anchuang.

[0045] Step 120: receiving reverse vehicle deviation information of the reverse vehicle.

[0046] When the forward vehicle and the reverse vehicle move towards each other, and the reverse vehicle collects the deviation of the driving trajectory of the forward vehicle, which threatens the reverse vehicle, the reverse vehicle generates and sends corresponding reverse vehicle deviation information. The reverse vehicle deviation information specifically includes the license plate number, deviation direction, and current time of the forward vehicle.

[0047] Step 130: judging whether the corresponding forward vehicle of the reverse vehicle deviates according to the forward vehicle image information and the reverse vehicle deviation information. If it deviates, generate and send safety information to the forward vehicle.

[0048] The step of judging whether the corresponding forward vehicle of the reverse vehicle deviates according to the forward vehicle image information and the reverse vehicle deviation information specifically includes: retrieving the forward vehicle image information of the corresponding forward vehicle of the reverse vehicle according to the reverse vehicle deviation information, obtaining the driving speed and driving trajectory of the corresponding forward vehicle according to the forward vehicle image information, and then judging whether the corresponding forward vehicle deviates according to the driving speed and driving trajectory of the corresponding forward vehicle.

[0049] For example, assume that a reverse vehicle starts to deviate from the normal driving route at a certain time, and the deviation information is recorded. In order to confirm whether the forward vehicle indeed deviates from the route, the forward vehicle image information of the corresponding time of the forward vehicle is retrieved. According to the deviation information of the reverse vehicle, the forward vehicle image information of the corresponding time is found. According to the forward vehicle image information, the driving speed and driving trajectory of the forward vehicle are obtained. According to the driving speed and driving trajectory of the forward vehicle, it is found that the forward vehicle indeed deviates from the route. Because the driving speed and driving trajectory of the forward vehicle do not match the normal route, it can be confirmed that the forward vehicle indeed deviates from the route.

[0050] The deviation information of the reverse vehicle and the image information of the forward vehicle at the corresponding time are collected. This data can be obtained through road monitoring cameras, traffic monitoring systems, vehicle-mounted GPS, etc. After obtaining the data, it needs to be processed and analyzed. Computer vision and image processing technology can be used to extract the driving speed and trajectory of the forward vehicle and compare it with the normal route. Through existing devices such as road monitoring cameras, traffic monitoring systems, vehicle-mounted GPS, etc., the vehicle deviation can be corrected.

[0051] According to the collected forward vehicle image information, it is verified whether the information sent by the reverse vehicle is real, ensuring the accuracy of the information and avoiding subsequent work.

[0052] The forward vehicle safety information specifically includes license plate number, speed limit, and driving direction.

[0053] When the driving speed of the forward vehicle is greater than the first preset speed, vehicle safety information is generated and sent to the reverse vehicle. If the driving speed of the forward vehicle is relatively fast, the forward vehicle may appear some border crossing situations, which will still pose a threat to the reverse vehicle. At this time, the reverse vehicle needs to move away from the middle part of the boundary line to reduce the occurrence of collision. The reverse vehicle safety information specifically includes safety direction information.

[0054] When the driving speed of the forward vehicle is greater than the second preset speed, vehicle braking instruction information is generated and sent to the forward vehicle. In the downlink process, the forward vehicle may lose control. At this critical moment, the forward vehicle braking instruction information is used to assist the vehicle to stop. Specifically, when the driving speed of the normal vehicle exceeds the second preset speed, the forward vehicle braking instruction information is generated and sent. The first preset speed and the second preset speed are specifically set according to the slope speed limit and historical traffic accidents, etc.

[0055] It also includes emitting a preset frequency flashing prompt light to the deviated forward vehicle. Through this light prompt, the driver is quickly reminded to control the vehicle in time. The prompt light is specifically emitted to the vehicle head, and the prompt light is specifically red.

[0056] It also includes sending vehicle distance keeping information to the rear vehicle of the deviated forward vehicle. When the forward vehicle controls the vehicle speed, the distance between the forward vehicle and the rear vehicle will be reduced. It is difficult to timely control the distance on the slope. By sending the vehicle distance keeping information, the rear vehicle can timely control the vehicle speed and keep the distance, reducing the occurrence of collision accidents.

[0057] 1302: It also includes collecting slope accident image information and sending slope accident image information and forward vehicle safety information to the cloud.

[0058] The accident image information after sending the forward vehicle safety information is collected, and the background personnel adjusts the limit speed according to the limit speed in the accident image information and the forward vehicle safety information, reduces the occurrence of traffic accidents, and improves the safety of the slope.

[0059] The embodiment can timely exchange information of the forward and reverse vehicles by collecting, receiving, processing and sending information at the slope, relaying and forwarding, the driver can timely obtain information on the other relative slope surface of the slope, timely deliver the information to the driver, ensure the safety of the vehicle, avoid information transmission delay of the network equipment; the reverse vehicle deviation information obtained by the reverse vehicle is received, then the corresponding reverse vehicle image information is obtained, and it is judged whether the corresponding reverse vehicle is really deviated, so as to verify and judge, and ensure the accuracy of the information; the forward vehicle safety information is sent, the corresponding forward vehicle is timely informed to control the speed and the running track of the vehicle, effectively avoids, and reduces the traffic accidents caused by the visual blind area; the driver is quickly reminded by the light prompt, the driver timely controls the vehicle; the vehicle distance keeping information is sent, the rear vehicle can timely control the vehicle speed, keep the distance, and reduce the occurrence of collision accidents; the accident image information after sending the forward vehicle safety information is collected, the background personnel reduces the occurrence of traffic accidents according to the limit speed in the accident image information and the forward vehicle safety information, and improves the safety of the slope.

[0062] The receiving module 320 is used for receiving reverse vehicle deviation information of the reverse vehicle.

[0063] The processing module 330 judges whether the reverse vehicle deviates from the corresponding forward vehicle according to the forward vehicle image information and the reverse vehicle deviation information, and generates and sends safety information to the forward vehicle if deviating.
