Based on the above road congestion illegal parking monitoring system based on the RFID technology, embodiments of the road congestion illegal parking monitoring method based on the RFID technology are provided.
Referring to fig. 2, a first embodiment of the method for monitoring road congestion violation based on an RFID technology according to the present application provides a method for monitoring road congestion violation based on an RFID technology, where the method includes:
step S10, acquiring a preset time period, and scanning a first scanning result obtained by a Radio Frequency Identification (RFID) detector according to a preset time frequency, wherein the first scanning result is carried by a bound first RFID electronic tag carried by a target vehicle;
at present, there are many ways of monitoring the vehicle running conditions, such as using a ground sensing coil, a microwave detector and a radar, which can detect the number of vehicles in a measurement range, but cannot accurately reflect the congestion state of the vehicles, and further, like a detection method based on a GPS technology, because data is grasped on a few mechanisms, the detection method is usually difficult to obtain, or only can obtain partial data, and cannot support the application scene of the whole traffic congestion detection, whereas the vehicle congestion method using a video recognition technology needs to install a high-precision camera, a deep learning chip and an upright rod, needs to supply commercial power, needs to install a large amount of wiring, and is also affected by environments such as fog, rain, night, and the like. Therefore, the current vehicle running condition monitoring accuracy and convenience are low. Therefore, according to the road congestion illegal parking monitoring method based on the RFID technology, the relevant data of the vehicle running state can be obtained through the RFID detector and the RFID electronic tag carried and bound by the target vehicle, a high-precision camera, a deep learning chip and a vertical rod do not need to be installed, and the mains supply does not need to be supplied, so that a large amount of wiring is not needed; and environmental influences such as heavy fog, rain, night and the like are avoided, so that the road congestion and illegal parking monitoring accuracy and convenience are improved.
The method and the device utilize the RFID technology to monitor the running condition of the target vehicle, the RFID (Radio frequency identification) technology is a non-contact automatic identification technology, and the basic principle is that the automatic identification of the identified object is realized by utilizing the transmission characteristics of Radio frequency signals, space coupling (inductance or electromagnetic coupling) and radar reflection. The RFID electronic tag is encrypted, and the content of the tag can be only identified by an RFID detector of the system. The RFID technology is low in cost, and compared with the GPS and video identification technology, the implementation cost can be greatly reduced (the equipment cost of the GPS and video identification technology is too high, the cost is extremely high due to the fact that a high-precision camera and a deep learning chip are needed, and the installation cost is too high, in the installation process, a vertical rod is needed to be installed, commercial power is needed to be supplied, and a large amount of installation and wiring costs are needed). Compared with the video recognition technology, the RFID technology is not influenced by environmental factors, and can still normally work even in severe environments (weather conditions such as heavy fog, heavy rain, night and the like) (the video recognition technology is easy to occur under the conditions of poor angles or poor weather and darkness, and similar letters and numbers such as 8 and B are easy to recognize and confuse to cause the problem of mistaken recognition of license plates and wrong judgment, and the video recognition technology cannot solve the problem of fake plate vehicles.
Due to the fact that the ultrahigh frequency RFID electronic tag does not need to be powered through equipment to achieve wireless communication, ultra-low power consumption wireless communication with the outside is achieved. The RFID electronic tag is a data carrier of the running condition of a target vehicle in a road congestion illegal parking monitoring system based on an RFID technology, and consists of a tag antenna and a tag special chip. The RFID detector is in wireless communication with the RFID electronic tag through the antenna, so that the reading or writing operation of the tag identification code and the memory data (the data of the running condition of the target vehicle) of the RFID electronic tag can be realized; the RFID detector is placed on the road where the target vehicle is traveling, and a typical RFID detector includes a high frequency module (transmitter and receiver), a control unit, and a reading antenna.
The road congestion illegal parking monitoring method based on the RFID technology can be applied to a road congestion illegal parking monitoring system based on the RFID technology. In the technical scheme disclosed by the application, a vehicle monitoring server obtains a preset time period, and a Radio Frequency Identification (RFID) detector scans a first scanning result obtained by a bound RFID electronic tag carried by a target vehicle according to a preset time frequency; specifically, when some vehicles need to be monitored, the RFID electronic tag can be bound with the vehicle, and attached to the vehicle to form a target vehicle; the radio frequency identification RFID detector is arranged on the side of a road and scans a bound RFID electronic tag carried by a target vehicle according to a preset time frequency, and then the vehicle monitoring server acquires a first scanning result of a preset time period.
Step S20, acquiring the preset time period, and scanning a second scanning result obtained by the RFID detector according to the preset time frequency, wherein the second scanning result is obtained by scanning second RFID electronic tags bound with other vehicles in the area where the target vehicle is located;
in the technical solution disclosed in the present application, the vehicle monitoring server scans, for the same preset time period as that in step S10, a second scanning result obtained by scanning, by the same RFID detector as that in step S10, the second RFID electronic tags bound to other vehicles in the area where the target vehicle is located according to the same preset time frequency as that in step S10.
A step S30 of determining an operation state of the target vehicle based on the first scanning result and the second scanning result;
in the technical scheme disclosed by the application, after the vehicle monitoring server obtains the first scanning result and the second scanning result in the preset time period, the road congestion violation monitoring program based on the RFID technology analyzes the first scanning result and the second scanning result, and the running state of the target vehicle is judged.
Step S40, a monitoring result regarding the running state of the target vehicle is output.
In the technical scheme disclosed by the application, a road congestion illegal parking monitoring program based on the RFID technology outputs a monitoring result about the running state of a target vehicle according to the running state of the target vehicle, so that a vehicle running monitoring center can monitor the target vehicle based on the monitoring result and preset traffic rules; the preset traffic rules include safety traffic rules such as vehicle violation, vehicle overspeed and the like and traffic rules that can be set specifically according to special monitoring requirements, and are not limited herein.
In the embodiment, a road congestion violation monitoring method based on an RFID technology acquires a preset time period, and a Radio Frequency Identification (RFID) detector scans a first scanning result obtained by a first RFID electronic tag bound to a target vehicle according to a preset time frequency; acquiring the preset time period, and scanning a second scanning result obtained by binding a second RFID electronic tag carried by other vehicles in the area where the target vehicle is located by the RFID detector according to the preset time frequency; determining an operating state of the target vehicle based on the first scanning result and the second scanning result; the monitoring result of the running state of the target vehicle is output, so that the relevant data of the running state of the vehicle can be obtained by the radio frequency identification RFID detector and the RFID electronic tag carried and bound by the target vehicle, a high-precision camera, a deep learning chip and a vertical rod do not need to be installed, and the mains supply does not need to be supplied, so that a large amount of wiring is not needed; and environmental influences such as heavy fog, rain, night and the like are avoided, so that the road congestion and illegal parking monitoring accuracy and convenience are improved.
Further, in the second embodiment of the road congestion violation monitoring method based on the RFID technology, referring to fig. 3, before step S10, the method includes:
step S01, acquiring the monitoring range of the RFID detector, and dividing the target monitoring area into monitoring sub-areas with preset number based on the monitoring range;
in the technical scheme disclosed in the application, the monitoring range of the radio frequency identification RFID detector can generally reach the coverage area with the RFID detector as the center and the radius of 20-80 m, so that the deployment number of the RFID detector can be adjusted according to the actual road condition and the monitoring precision requirement, for example, if the requirement on monitoring data is accurate, the deployment density of the RFID detector can be increased, and the coverage area of a single RFID detector is reduced, otherwise, if the requirement on monitoring data is not high, the deployment density of the RFID detector can be reduced, and the coverage area of the single RFID detector is increased. It can be understood that, after the monitoring range of the RFID detector is defined, the length of the target monitoring area may be divided by the monitoring diameter of the RFID detector, and the obtained value is the number of the target monitoring area divided into the monitoring sub-areas.
Referring to fig. 5, fig. 5 is a schematic view of an application scenario of the road congestion violation monitoring method based on the RFID technology. Assuming that the monitoring ranges of the RFID detector 1 and the RFID detector 2 are both 20 meters in radius and the length of the target monitoring area (road segment 1 plus road segment 2) is 80 meters, two RFID detectors are required to monitor the road segment 1 and the road segment 2, the monitoring range of the RFID detector 1 is the road segment 1, and the monitoring range of the RFID detector 2 is the road segment 2.
Step S02, acquiring device identifiers carried by the RFID detectors deployed in the monitoring sub-areas and the association relationship between the RFID detectors and the geographical positions of the monitoring sub-areas;
in the technical scheme disclosed by the application, the equipment identification carried by each RFID detector refers to which RFID detector the first scanning result obtained by subsequent road congestion violation monitoring program based on the RFID technology belongs to for scanning; the association relationship between the RFID detectors and the geographic positions of the monitoring sub-areas in which the RFID detectors are respectively located refers to one-to-one correspondence between the RFID detectors and the geographic positions of the monitoring sub-areas in which the RFID detectors are respectively located, namely the RFID detectors are bound with the geographic position information of the monitoring sub-areas, so that the positions of the vehicles can be determined according to the scanned RFID detectors of the RFID electronic tags of the vehicles and the geographic position information of the RFID detectors.
Step S03, obtaining subarea marks carried by each monitored subarea;
in the technical scheme disclosed by the application, the sub-region identification carried by the monitoring sub-region where each RFID detector is located refers to the monitoring sub-region corresponding to the RFID detector to which the first scanning result obtained by the subsequent road congestion violation monitoring program based on the RFID technology belongs, so as to obtain the second scanning result sent by the RFID detector corresponding to the monitoring sub-region.
