Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system configurations, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
In order to illustrate the technical solutions proposed in the embodiments of the present application, the following description is made by specific embodiments.
The following describes an identification system of a vehicle-mounted electronic tag provided in an embodiment of the present application. Referring to fig. 1, fig. 1 shows an architecture example of the identification system of the vehicle-mounted electronic tag. The recognition system of the vehicle-mounted electronic tag comprises:
the road side unit is used for communicating with the vehicle-mounted electronic tag to obtain the position of the vehicle-mounted electronic tag;
radar for detecting a position of a vehicle;
the upper computer is respectively connected with the road side unit and the radar and is used for receiving the position of the vehicle-mounted electronic tag sent by the road side unit and the position of the vehicle sent by the radar and identifying the number of the vehicle-mounted electronic tags on the vehicle according to the position of the vehicle and the position of the vehicle-mounted electronic tag.
Wherein the roadside unit may be installed at an expressway. The roadside unit has an antenna which can communicate with the vehicle-mounted electronic tags within a certain range by means of a dedicated short range communication technique (Dedicated Short Range Communication, DSRC), thereby determining the location of each vehicle-mounted electronic tag within the range from the communication data and effecting a highway toll transaction with each vehicle-mounted electronic tag. The above range refers to a communication range of the roadside unit, and the communication range can be adjusted by adjusting the antenna parameters of the roadside unit. For example, the communication range of the roadside unit may be adjusted to the parking transaction area of the expressway. After the road side unit determines the positions of the vehicle-mounted electronic tags within the certain range, the positions of the vehicle-mounted electronic tags can be sent to the upper computer.
Such radars may include, but are not limited to, millimeter wave radars and lidars. The radar sends out a wave beam through the antenna of the radar, the wave beam is reflected back by touching an object, and the radar determines the position of the vehicle according to the reflected wave beam. Wherein the vehicle may be a vehicle waiting in a parking transaction area. After the radar determines the position of the vehicle, the position of the vehicle may be transmitted to an upper computer.
The upper computer can receive the position of the vehicle-mounted electronic tag sent by the road side unit and the position of the vehicle sent by the radar. The upper computer can identify the number of the vehicle-mounted electronic tags mounted on the vehicle according to the positions of the vehicle-mounted electronic tags and the positions of the vehicle.
Optionally, the upper computer may further perform time synchronization processing on the roadside unit and the radar, so that local clocks of the roadside unit and the radar are consistent. Under the condition that local clocks of the road side unit and the radar are consistent, the upper computer can determine the position of the vehicle-mounted electronic tag and the position of the vehicle at the same moment according to the time stamp of the road side unit for the position of the vehicle-mounted electronic tag and the time stamp of the radar for the position of the vehicle. In this way, the number of the in-vehicle electronic tags on the vehicle can be more accurately identified.
In some embodiments, if there is a time difference between the position of the vehicle and the position of the in-vehicle electronic tag, such as the position of the vehicle is a first second position and the position of the in-vehicle electronic tag is a second position, the radar may predict the position of the vehicle in the second position according to the speed of the vehicle and the position of the vehicle in the first second position to provide the time-synchronized vehicle position and the in-vehicle electronic tag position to the host computer.
Optionally, as shown in fig. 1, the recognition system of the vehicle-mounted electronic tag may further include a camera, where a dotted line between the camera and the upper computer indicates the camera as an optional item, and the camera is connected with the upper computer and is used for capturing a license plate image of the vehicle and sending the license plate image to the upper computer. The upper computer can identify the license plate number of the vehicle according to the license plate image. After the number of the vehicle-mounted electronic tags on the vehicle is identified, the upper computer can store the license plate number of the vehicle and the number of the vehicle-mounted electronic tags on the vehicle in a correlated mode, so that a traffic management department can screen vehicles for escaping toll according to stored information.
From the above, the method and the device acquire the position of the vehicle and the position of the vehicle-mounted electronic tag, and then can identify the number of the vehicle-mounted electronic tags on the vehicle according to the position of the vehicle and the position of the vehicle-mounted electronic tag. When the vehicle is at a high speed, the number of the vehicle-mounted electronic tags mounted on the vehicle is rapidly identified through the position of the vehicle and the position of the vehicle-mounted electronic tags, and a high-speed toll collector can timely find out vehicles with abnormal numbers according to the number of the vehicle-mounted electronic tags mounted on the vehicle, so that the behavior of a vehicle owner can be effectively standardized, and the vehicle owner is prevented from stealing toll by mounting a plurality of vehicle-mounted electronic tags on the vehicle.
Based on the above-mentioned recognition system of the vehicle-mounted electronic tag, a method for recognizing the vehicle-mounted electronic tag provided in the embodiment of the application is described below. Referring to fig. 2, the method for identifying the vehicle-mounted electronic tag can be applied to the upper computer in fig. 1. The identification method of the vehicle-mounted electronic tag comprises the following steps:
In the embodiment of the application, the upper computer is connected with the road side unit and the radar respectively, and can receive the position of the vehicle-mounted electronic tag sent by the road side unit and the position of the vehicle sent by the radar. The vehicle is a specific vehicle needing to identify the number of the vehicle-mounted electronic tags, for example, the vehicle can be one vehicle located in a parking transaction area of a high-speed intersection. It should be noted that the road side unit may determine the positions of a plurality of vehicle-mounted electronic tags within the communication range. The upper computer can determine a plurality of vehicle-mounted electronic tags according to the positions of the vehicle and the positions of the plurality of vehicle-mounted electronic tags, wherein a plurality of vehicle-mounted electronic tags are positioned on the vehicle. It should be understood that if there is only one in-vehicle electronic tag within the communication range of the roadside unit, the host computer only recognizes whether the one in-vehicle electronic tag is located on the vehicle. Of course, if only one vehicle-mounted electronic tag is in the communication range, the upper computer can not identify the number of the vehicle-mounted electronic tags on the vehicle, and only if the number of the vehicle-mounted electronic tags in the communication range is more than two, the upper computer can identify the number of the vehicle-mounted electronic tags on the vehicle and send an alarm when the number of the vehicle-mounted electronic tags on the vehicle is more than two, so as to remind expressway toll collection personnel.
In some embodiments, in order to accurately identify the number of the electronic tags on the vehicle, the step 203 includes:
the in-vehicle electronic tag having the same position as the vehicle is identified as an in-vehicle electronic tag on the vehicle.
And counting the number of the vehicle-mounted electronic tags on the vehicle.
And judging whether the position of each vehicle-mounted electronic tag detected by the road side unit is the same as the position of the vehicle, and if so, determining that the vehicle-mounted electronic tag is the vehicle-mounted electronic tag on the vehicle with the number of the vehicle-mounted electronic tags to be identified. After the judging step is executed for each vehicle-mounted electronic tag, the number of the vehicle-mounted electronic tags on the vehicle can be counted.
For example, assuming that the radar detects the position of the vehicle a located in the parking transaction area of the high-speed intersection, the road side unit locates the position of the vehicle-mounted electronic tag B1, the position of the vehicle-mounted electronic tag B2 and the position of the vehicle-mounted electronic tag B3 within the communication range, wherein the positions of the vehicle-mounted electronic tag B1 and the vehicle-mounted electronic tag B2 are the same as the position of the vehicle a, and the positions of the vehicle-mounted electronic tag B3 are different from the position of the vehicle a, the upper computer may identify the vehicle-mounted electronic tag B1 and the vehicle-mounted electronic tag B2 as the vehicle-mounted electronic tags on the vehicle a, and further count the number of the vehicle-mounted electronic tags on the vehicle a to be 2.
Alternatively, the position of the vehicle is represented by a position range, which may be a body area range of the vehicle, and the position of the in-vehicle electronic tag is represented by a position point. As shown in fig. 3, the position of the vehicle is a rectangular range in the figure, and three dots respectively represent the positions of three in-vehicle electronic tags. When the position of the vehicle-mounted electronic tag is located in the position range of the vehicle, the position of the vehicle-mounted electronic tag is determined to be the same as the position of the vehicle. Taking fig. 3 as an example, the positions of the vehicle-mounted electronic tags represented by the two dots located within the rectangular range are the same as the positions of the vehicle, and the positions of the vehicle-mounted electronic tags represented by the two dots located outside the rectangular range are different from the positions of the vehicle.
Alternatively, the position of the vehicle and the position of the in-vehicle electronic tag are each represented by a position point. For example, the center position of the vehicle may be set as a position point of the vehicle, and the preset distance threshold value may be set to a radius of a circumscribed circle of a body region (rectangular region) of the vehicle. And when the distance between the position point of the vehicle-mounted electronic tag and the position point of the vehicle does not exceed the preset distance threshold value, determining that the position of the vehicle-mounted electronic tag is the same as the position of the vehicle.
In some embodiments, in order to determine the identity of the vehicle, the method for identifying an in-vehicle electronic tag further includes:
and acquiring license plate images of the vehicle through the camera.
And identifying the license plate number of the vehicle according to the license plate image.
And storing the license plate number of the vehicle and the number of the vehicle-mounted electronic tags on the vehicle in a correlated manner.
The camera is connected with the upper computer and used for shooting license plate images of the vehicle. The upper computer can acquire license plate images of the vehicle through the camera. The upper computer can identify the license plate number in the license plate image through an image identification technology. After the number of the vehicle-mounted electronic tags on the vehicle is identified, the upper computer can store the license plate number of the vehicle and the number of the vehicle-mounted electronic tags on the vehicle in a correlated mode, so that a traffic management department can screen vehicles for escaping toll according to stored information.
In some embodiments, the position of the vehicle may be detected by a radar or a camera, and the position of the vehicle-mounted electronic tag may be obtained by communicating with the vehicle-mounted electronic tag through a road side unit. In other embodiments, the position of the vehicle may also be obtained by fusion of the sensing data of the radar and the camera. Specifically, the upper computer can acquire a first position of the vehicle through the radar, acquire a second position of the vehicle through the camera, and then acquire a final position of the vehicle according to the first position and the second position, so that the accuracy of vehicle position detection is improved.
From the above, the method and the device acquire the position of the vehicle and the position of the vehicle-mounted electronic tag, and then can identify the number of the vehicle-mounted electronic tags on the vehicle according to the position of the vehicle and the position of the vehicle-mounted electronic tag. When the vehicle is at a high speed, the number of the vehicle-mounted electronic tags mounted on the vehicle is rapidly identified through the position of the vehicle and the position of the vehicle-mounted electronic tags, and a high-speed toll collector can timely find out vehicles with abnormal numbers according to the number of the vehicle-mounted electronic tags mounted on the vehicle, so that the behavior of a vehicle owner can be effectively standardized, and the vehicle owner is prevented from stealing toll by mounting a plurality of vehicle-mounted electronic tags on the vehicle.
