Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
As shown in fig. 1, which is a schematic diagram of a first embodiment of the road indicating system for a one-way road of the present invention, in the road indicating system of the present embodiment, the road indicating system is applied to a non-direct-view one-way road, the road has two ends a and B; the road indicating system has an indicating unit including a first indicating unit 11 and a second indicating unit 12, a first photographing unit 13, a second photographing unit 14, a road vehicle identifying unit 15, and a central processing unit 16.
The first indicating unit 11 is installed at the end A of the one-way road, the second indicating unit 12 is installed at the end B of the one-way road, and they respectively indicate whether the driver A and the driver B located at the end A of the one-way road can drive into the one-way road, for example, the driver can be prohibited from driving into the one-way road by the red light lighting indication, and the driver can drive into the one-way road by the green light lighting indication. The green light can be matched with a yellow light for indication, the green light is turned on for indication and can drive into the one-way road, the yellow light indicates that the driving vehicle can drive into the one-way road or does not drive into the one-way road according to the current situation, the green light is matched with the yellow light to form an indication unit to indicate that a driver can drive into the one-way road when the driving vehicle drives into the one-way road, and the red light is matched with the yellow light to form the indication unit to indicate that the driver cannot drive into the one-way road when the driving vehicle does not drive into the one-way road.
The first photographing unit 13 and the second photographing unit 14 are installed at the a-side and the B-side of the one-way road, respectively, to photograph vehicles entering and exiting the a-side and the B-side, respectively. A typical camera unit may be, for example, a camera, and the captured image may be in the form of a picture or a video.
The images captured by the first capturing unit 13 and the second capturing unit 14 are transmitted to the road-vehicle identifying unit 15, and the vehicle identifying unit 15 analyzes the images captured by the first end capturing unit 13 and the second end capturing unit 14 to identify whether a vehicle enters a one-way road and whether a vehicle that has entered the one-way road exits the one-way road. If the image is in a picture form, the picture can be directly analyzed, and if the image is in a video form, the picture can be extracted from the video for analysis. During analysis, each picture can be analyzed (a video can be regarded as a set of a plurality of continuous pictures), or some pictures can be selected for analysis according to a preset mode. If the video mode is adopted, a picture is extracted from the video image every 5 seconds for analysis. The vehicle recognition unit 15 recognizes whether or not a vehicle enters the one-way lane and whether or not a vehicle that has entered the one-way lane exits the one-way lane can be realized by analyzing the conditions of each vehicle entering and exiting the one-way lane individually based on the license plate number of the vehicle, and judging that no vehicle is located on the one-way lane when each license plate number of the entering one-way lane exits the one-way lane; when the license plate number of the single-track road is not driven out of the single-track road, judging that the vehicle is driven into one end of the single-track road and is not driven out of the other end. If the vehicle with the license plate number of Yue B xxxxx is analyzed to enter the end A, and the vehicle with the license plate number is analyzed to exit at the end B, the vehicle is judged not to be in the one-way road, otherwise, the vehicle is positioned in the one-way road. Thus, each entering vehicle is judged, when all the entering vehicles exit from the other end, the fact that no vehicle exists in the one-way road is indicated, and otherwise, the fact that the vehicle is located in the one-way road is indicated.
A central processing unit 16 for controlling the instruction unit to instruct according to whether the vehicle identified by the road vehicle identification unit enters the one-way lane or not and whether the vehicle entering the one-way lane is caused to exit the one-way lane or not; when no vehicle is positioned on the one-way road, the central processing unit 16 controls the indicating unit to indicate that the end A and the end B of the one-way road allow the vehicle to drive in; when a vehicle enters the first end of the one-way road and does not exit the second end, the central processing unit 16 controls the indicating unit to indicate that the second end is prohibited from entering.
In this embodiment, the central processing unit also has how to work to process the driving of the following vehicles, and the following selection is to analyze that the vehicle is driven into the end a, and the principle of the driving of the vehicle into the end B is the same. After a vehicle enters the end A, the central processing unit controls the indicating unit to indicate the end A to allow a first preset number of subsequent vehicles to enter, and after the vehicle enters the first preset number of vehicles, the central processing unit indicates the end A to prohibit entering until the end B enters a second preset number of vehicles and all the entering vehicles exit the first end; when the vehicles drive into the B, the central processing unit controls the indicating unit to indicate that the B allows the subsequent vehicles with the number of (the second preset number of-1) to drive in, and after the vehicles with the number of (the second preset number of-1) are driven in, the central processing unit indicates the B end to prohibit the driving in until the A drives into the vehicles with the number of (the first preset number of +1) and all the driven vehicles drive out of the B end. In short, once the A end drives in the vehicle, the A end allows the vehicles with certain data volume to drive in together, the B end prohibits the driving in before all the driven-in vehicles drive out of the B end, after all the driven-in vehicles drive out of the B end, the B end indicates that the driven-in vehicles can drive in and allows a certain number of vehicles to drive in together, and the A end prohibits the driving in before the driven-in vehicles drive out of the A end when the B end drives in all the vehicles.
Preferably, the total number of vehicles allowed to enter at the a-side and the total number of vehicles allowed at the B-side are the same, and the first preset number is equal to (the second preset number-1). Preferably, the first predetermined number is equal to 0, and the end a and the end B in turn each allow entry of 1 vehicle.
Further, in the embodiment, when the vehicle is allowed to enter the end a of the one-way road but no vehicle enters the one-way road, and no vehicle exists in the one-way road, the central processing unit controls the indicating unit to allow the end B to allow the vehicle to enter the one-way road; when the vehicle starts to drive in and does not drive out of the one-way road at the end B, the central processing unit controls the indicating unit to indicate that the driving is forbidden to be driven in. Therefore, the situation that the A end allows the driving-in of the B end and prohibits the driving-in of the B end can be avoided, but the A end does not have a vehicle to drive in within the preset time so as to cause time waste, and the B end works according to the method after the vehicle drives in the B end.
It should be understood that the central processing unit and the image processing unit according to the present invention may be integrated into one processor and the corresponding auxiliary devices from a physical point of view. The central processing unit and/or the image processing unit of the present invention may be physically divided into two parts, which are respectively located at the first end and the second end of the road, and are used together to implement the above-mentioned functions of the present invention.

If the number of the vehicles entering the end A is larger than that of the vehicles leaving the end B, the vehicles are positioned on the one-way road.
In this embodiment, when a vehicle enters the end a of the one-way road, the central processing unit controls the indication unit to indicate that the end a allows a subsequent vehicle to enter within a preset time, and after the preset time, indicates that the end a is prohibited from entering until the end B enters the vehicle and the preset time passes; and after the next preset time, the central processing unit controls the indicating unit to indicate the end B to allow the subsequent vehicle to drive in, and after the next preset time, the central processing unit indicates the end B to prohibit the vehicle from driving in until the end A drives in and the preset time passes. In short, the method means that the end A allows the vehicle to enter within a period of time once the end A starts to enter the vehicle, and after all the entering vehicles exit the end B, the end B starts to enter the vehicle, and the time for allowing the entering vehicles is the same. This is repeated.
