The present application provides a road congestion and illegal parking monitoring system based on RFID technology, the road congestion and illegal parking monitoring system based on RFID technology includes: an RFID electronic tag, an RFID detector, a communication module and a server;

The RFID electronic tag, the RFID detector and the server are connected to each other through the communication module;

The RFID electronic tag is a passive ultra-high frequency RFID electronic tag and is installed on the target vehicle and is uniquely bound to the target vehicle;

The RFID detector is arranged on the road where the target vehicle passes;

The server includes a first scanning result acquisition module, a second scanning result acquisition module, a running state determination module and a monitoring result output module.

Based on the above-mentioned road congestion and illegal parking monitoring system based on RFID technology, various embodiments of the road congestion and illegal parking monitoring method based on RFID technology of the present application are proposed.

2 , the first embodiment of the road congestion and illegal parking monitoring method based on RFID technology of the present application provides a road congestion and illegal parking monitoring method based on RFID technology, the method comprising:

Step S10, obtaining a preset time period, and the radio frequency identification RFID detector scans the first RFID electronic tag bound to the target vehicle according to the preset time frequency to obtain a first scanning result;

At present, there are many ways to monitor the operation status of vehicles, such as using ground sensing coils, microwave detectors and radars, etc. These methods can detect the number of vehicles within the measurement range, but they cannot accurately reflect the congestion status of vehicles. For example, the detection method based on GPS technology is usually difficult to obtain because the data is mastered by a few institutions, or only part of the data can be obtained, which cannot support the application scenario of the entire traffic congestion detection. The vehicle congestion method using video recognition technology requires the installation of high-precision cameras, deep learning chips and pole installation, and requires city power supply, requires a lot of wiring and is also affected by fog, rain, night and other environmental factors. It can be seen that the current vehicle operation status monitoring accuracy and convenience are low. Therefore, through the road congestion and illegal parking monitoring method based on RFID technology in this application, the RFID detector and the RFID electronic tag bound to the target vehicle can be used to obtain the relevant data of the vehicle operation status, without the need to install high-precision cameras, deep learning chips and pole installation, nor does it require city power supply, so there is no need for a lot of wiring; and it avoids the influence of fog, rain, night and other environmental factors, thereby improving the accuracy and convenience of road congestion and illegal parking monitoring.

This application uses RFID technology to monitor the operating status of the target vehicle. RFID (Radio Frequency Identification) technology is a contactless automatic identification technology. Its basic principle is to use the transmission characteristics of radio frequency signals and spatial coupling (inductive or electromagnetic coupling) and radar reflection to achieve automatic identification of the identified object. The RFID electronic tag is encrypted, and the tag content can only be recognized by the RFID detector of this system. RFID technology is low-cost and can greatly reduce the implementation cost compared to GPS and video recognition technology (the equipment cost of GPS and video recognition technology is too high: high-precision cameras and deep learning chips are required, which are extremely expensive; the installation cost is too high: during the installation process, poles need to be installed and AC power supply is required, which requires a lot of installation and wiring costs). Compared with video recognition technology, RFID technology will not be affected by environmental factors and can still work normally even in harsh environments (fog, heavy rain, night and other weather conditions) (video recognition technology is prone to occur in poor angles or bad weather or darkness. For similar letters and numbers, such as "8" and "B", it is easy to confuse them, resulting in misidentification of license plates and wrong judgments. In addition, video recognition technology cannot solve the problem of duplicate license plate vehicles. Since video recognition technology is based on identifying license plate numbers, if the license plate is duplicated, there will be serious problems of misidentification of license plates and wrong judgments). RFID technology does not need to damage the road surface or create obstacles during installation. It is quick and convenient to install, and the installation and maintenance costs are extremely low.

Since the ultra-high frequency RFID electronic tag does not need to be powered by the device to achieve wireless communication, it can achieve ultra-low power wireless communication with the outside world. The RFID electronic tag is a data carrier of the target vehicle's operating conditions in the road congestion and illegal parking monitoring system based on RFID technology. The RFID electronic tag consists of a tag antenna and a tag-specific chip. The RFID detector communicates wirelessly with the RFID electronic tag through the antenna, and can read or write the tag identification code and memory data (data on the target vehicle's operating conditions) of the RFID electronic tag; the RFID detector is set on the road where the target vehicle passes, 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 RFID technology of this application can be applied to the road congestion illegal parking monitoring system based on RFID technology. In the technical solution disclosed in this application, the vehicle monitoring server obtains a preset time period, and the radio frequency identification RFID detector scans the bound RFID electronic tag carried by the target vehicle according to the preset time frequency to obtain the first scanning result; specifically, when it is necessary to monitor the operation of certain vehicles, the RFID electronic tag can be bound to the vehicle, and the RFID electronic tag can be attached to the vehicle to form a target vehicle; the radio frequency identification RFID detector is set on the side of the road and scans the bound RFID electronic tag carried by the target vehicle according to the preset time frequency, and then the vehicle monitoring server obtains the first scanning result of the preset time period.

Step S20, obtaining the preset time period, the RFID detector scanning the second RFID electronic tags bound to other vehicles in the area where the target vehicle is located according to the preset time frequency to obtain a second scanning result;

In the technical solution disclosed in the present application, the vehicle monitoring server provides a second scanning result in the same preset time period as step S10, and the second scanning result is obtained by scanning the second RFID electronic tags bound to other vehicles in the area where the target vehicle is located with the same RFID detector as step S10 at the same preset time frequency as step S10.

Step S30, determining the running state of the target vehicle based on the first scanning result and the second scanning result;

In the technical solution disclosed in the present application, after the vehicle monitoring server obtains the first scanning result and the second scanning result of the preset time period, the road congestion and illegal parking monitoring program based on RFID technology analyzes the first scanning result and the second scanning result to determine the operating status of the target vehicle.

Step S40: outputting the monitoring result on the running status of the target vehicle.

In the technical solution disclosed in the present application, the road congestion and illegal parking monitoring program based on RFID technology outputs the monitoring results about the operating status of the target vehicle according to the operating status of the target vehicle, so that the vehicle operation monitoring center can monitor the target vehicle based on the monitoring results and preset traffic rules; the preset traffic rules include safety traffic rules such as illegal parking and speeding, and traffic rules that can be specially set according to special monitoring requirements, which are not restricted here.

In this embodiment, the road congestion and illegal parking monitoring method based on RFID technology obtains a preset time period, and the radio frequency identification RFID detector scans the first RFID electronic tag bound to the target vehicle according to the preset time frequency to obtain a first scanning result; obtains the preset time period, and the RFID detector scans the second RFID electronic tag bound to other vehicles in the area where the target vehicle is located according to the preset time frequency to obtain a second scanning result; based on the first scanning result and the second scanning result, the operating status of the target vehicle is determined; and the monitoring result about the operating status of the target vehicle is output, so that the radio frequency identification RFID detector and the RFID electronic tag bound to the target vehicle can obtain relevant data on the vehicle's operating status, without the need to install high-precision cameras, deep learning chips and pole installations, and no AC power supply is required, so a large amount of wiring is not required; and the influence of heavy fog, rain, night and other environmental factors is avoided, thereby improving the accuracy and convenience of road congestion and illegal parking monitoring.

Further, in the second embodiment of the road congestion illegal parking monitoring method based on RFID technology of the present application, referring to FIG. 3 , before step S10, it includes:

Step S01, obtaining the monitoring range of the RFID detector, and dividing the target monitoring area into a preset number of monitoring sub-areas based on the monitoring range;

In the technical solution disclosed in the present application, the monitoring range of the radio frequency identification RFID detector can generally reach a coverage area with a radius of 20 to 80m with the RFID detector as the center. Therefore, the number of deployed RFID detectors can be adjusted according to the actual road conditions and monitoring accuracy requirements. For example, if the monitoring data requires accuracy, the deployment density of the RFID detector can be increased and the coverage of a single RFID detector can be reduced. Conversely, if the monitoring data requirements are not high, the deployment density of the RFID detector can be reduced and the coverage of a single RFID detector can be increased. It can be understood that after clarifying the monitoring range of the RFID detector, the length of the target monitoring area can be divided by the monitoring diameter of the RFID detector, and the resulting value is the number of monitoring sub-areas into which the target monitoring area is divided.

Refer to Figure 5, which is a schematic diagram of an application scenario of the road congestion illegal parking monitoring method based on RFID technology in this application. Assuming that the monitoring range of RFID detector 1 and RFID detector 2 are both 20 meters in radius, and the length of the target monitoring area (section 1 plus section 2) is 80 meters, two RFID detectors are required to monitor section 1 and section 2, and the monitoring range of RFID detector 1 is section 1, and the monitoring range of RFID detector 2 is section 2.

Step S02, obtaining the device identification carried by each RFID detector deployed in each monitoring sub-area, and the association relationship between each RFID detector and the geographical location of the respective monitoring sub-area;

In the technical solution disclosed in the present application, the device identification carried by each RFID detector refers to the device identification carried by the subsequent road congestion and illegal parking monitoring program based on RFID technology to identify which RFID detector the first scanning result obtained belongs to; the geographical location association relationship between each RFID detector and its respective monitoring sub-area refers to the one-to-one correspondence between the RFID detector and the geographical location of its respective monitoring sub-area, that is, the RFID detector is bound to the geographical location information of the monitoring sub-area, so the location of the vehicle can be determined based on the RFID detector whose RFID electronic tag is scanned and the geographical location information of the RFID detector.

Step S03, obtaining the sub-area identifier carried by each monitoring sub-area;

In the technical solution disclosed in the present application, the sub-area identifier carried by the monitoring sub-area where each RFID detector is located refers to the monitoring sub-area corresponding to the RFID detector to which the first scanning result obtained by the subsequent road congestion and illegal parking monitoring program based on RFID technology belongs, thereby obtaining the second scanning result sent by the RFID detector corresponding to the monitoring sub-area.

Step S04: Based on the geographic location association relationship, a relationship mapping table is generated corresponding to the bound and associated device identifiers and sub-area identifiers respectively.

In the technical solution disclosed in the present application, based on the geographical location association relationship, a relationship mapping table is generated corresponding to the bound and associated device identifiers and sub-area identifiers respectively. Specifically, after obtaining the relationship mapping table of the device identifier and the sub-area identifier through binding, the mapping table can be queried to obtain the geographical location at which the RFID detector is deployed, that is, which monitoring sub-area it corresponds to.

In this embodiment, the monitoring range of the RFID detector is obtained, and based on the monitoring range, the target monitoring area is divided into a preset number of monitoring sub-areas; the device identification carried by each RFID detector deployed in each of the monitoring sub-areas, and the geographical location association relationship between each RFID detector and the respective monitoring sub-area are obtained; the sub-area identification carried by each of the monitoring sub-areas is obtained; based on the geographical location association relationship, the device identification and sub-area identification that are bound to each other are respectively correspondingly, and a relationship mapping table is generated, so that the corresponding relationship between the RFID detector and the location can be clearly defined.

Further, in the third embodiment of the road congestion illegal parking monitoring method based on RFID technology of the present application, referring to FIG. 4 , step S30 includes:

Step S31, obtaining the start receiving time and the end receiving time of the first RFID electronic tag in the first scanning result, and calculating the first residence time of the first RFID electronic tag;

In the technical solution disclosed in the present application, it can be understood that the first residence time of the first RFID electronic tag can be calculated by subtracting the start reception time of the first RFID electronic tag from the end reception time of the first RFID electronic tag.

Step S32, obtaining the start receiving time and the end receiving time of each of the second RFID electronic tags in the second scanning result, and calculating the second residence time of each of the second RFID electronic tags;

In the technical solution disclosed in the present application, by the same token, the second residence time of the second RFID electronic tag can be calculated by subtracting the start reception time of the second RFID electronic tag from the end reception time of the second RFID electronic tag.

Step S33, calculating the average residence time of each of the second RFID electronic tags according to the number of the second RFID electronic tags and the sum of the second residence time;

In the technical solution disclosed in the present application, for example, when the number of the second RFID electronic tags is 5 and the sum of the second residence time is 40 minutes, the average residence time of the second RFID electronic tags is 8 minutes.

Step S34: determining the running state of the target vehicle based on the first stay time and the average stay time.

In the technical solution disclosed in the present application, the first residence time and the average residence time are compared to determine the running state of the target vehicle.

In this embodiment, the start receiving time and the end receiving time of the first RFID electronic tag in the first scanning result are obtained, and the first residence time of the first RFID electronic tag is calculated; the start receiving time and the end receiving time of each of the second RFID electronic tags in the second scanning result are obtained, and the second residence time of each of the second RFID electronic tags is calculated; according to the number of the second RFID electronic tags and the sum of the second residence times, the average residence time of each of the second RFID electronic tags is calculated; based on the first residence time and the average residence time, the running status of the target vehicle is determined, so that the radio frequency identification RFID detector and the RFID electronic tag bound to the target vehicle can obtain relevant data on the vehicle's running status, without the need to install high-precision cameras, deep learning chips, and pole installations, nor does it require AC power supply, so a large amount of wiring is not required; and the influence of environments such as fog, rain, and night is avoided, thereby improving the accuracy and convenience of road congestion and illegal parking monitoring.

Further, in the fourth embodiment of the road congestion illegal parking monitoring method based on RFID technology of the present application, step S34 includes:

Step S341, when the first residence time is greater than or equal to a first preset time threshold, and the average residence time is greater than or equal to a second preset time threshold, it is determined that the operating state of the target vehicle is a congested state, wherein the first preset time threshold is less than the second preset time threshold.

In the technical solution disclosed in the present application, when the first residence time is greater than or equal to the first preset time threshold, it can be judged that the target vehicle has stayed in the monitoring sub-area for a period of time. When the average residence time is greater than or equal to the second preset time threshold, it is judged that the target vehicle and other vehicles in the monitoring area have also stayed for a period of time. Therefore, the operating state of the target vehicle can be determined to be a congested state, so that the radio frequency identification RFID detector and the RFID electronic tag bound to the target vehicle can obtain relevant data on the vehicle's operating state. There is no need to install high-precision cameras, deep learning chips, and pole installation, nor does it require AC power supply, so there is no need for a large amount of wiring; and it avoids the influence of heavy fog, rain, night and other environmental factors, thereby improving the accuracy and convenience of road congestion and illegal parking monitoring.

Further, in the fifth embodiment of the road congestion illegal parking monitoring method based on RFID technology of the present application, step S34 also includes:

Step S342: when the first dwell time is greater than or equal to the first preset time threshold, and the average dwell time is less than the second preset time threshold, obtaining a device identifier carried by the RFID detector that sends the first scanning result;

In the technical solution disclosed in the present application, firstly, the device identification carried by the RFID detector that sends the first scanning result is obtained. For example, the device identification A carried by the RFID detector that sends the first scanning result is obtained.

Step S343, querying the relationship mapping table to obtain the sub-area identifier carried by the monitoring sub-area associated with the device identifier;

In the technical solution disclosed in the present application, it is assumed that the relationship mapping table is queried and the sub-area identifier B corresponding to the device identifier A is obtained.

Step S344, determining whether the sub-area mark belongs to a preset legal parking mark;

In the technical solution disclosed in the present application, a preset legal parking sign is added to the legal parking area.

Step S345: When the sub-area mark does not belong to the preset legal parking mark, it is determined that the running state of the target vehicle is an illegal parking state.

In this embodiment, when the first dwell time is greater than or equal to the first preset time threshold, and the average dwell time is less than the second preset time threshold, the device identifier carried by the RFID detector that sends the first scanning result is obtained; the relationship mapping table is queried to obtain the sub-area identifier carried by the monitoring sub-area associated with the device identifier; it is determined whether the sub-area identifier belongs to the preset legal parking identifier; when the sub-area identifier does not belong to the preset legal parking identifier, the operating status of the target vehicle is determined to be an illegal parking status, so that the radio frequency identification RFID detector and the RFID electronic tag bound to the target vehicle can obtain relevant data on the vehicle's operating status, without the need to install high-precision cameras, deep learning chips, and pole installations, nor does it require AC power supply, so a large amount of wiring is not required; and the influence of heavy fog, rain, night and other environmental factors is avoided, thereby improving the accuracy and convenience of road congestion and illegal parking monitoring.
