The speed camera is mainly used as a vehicle speed measuring device to control speeding. There are two types of speed cameras: fixed and mobile. There are three types of speed cameras: radar system using radio waves, laser system based on light reflection, and sensor system using sensor lines.

These devices measure the speed of a vehicle at a point on the road so that the vehicle can avoid speeding by slowing down only for a moment. In order to effectively control the speeding of the vehicle, a large number of speeding cameras are installed or a mobile type is used, but there are many difficulties in preventing the speeding, and it is expensive and not easy to install. It is also difficult to read pictures.

Accordingly, an object of the present invention is to apply a radio frequency identification device (RFID) to the vehicle speed measuring device to measure the average speed passing by one section and one section between two readers by installing RFID on the vehicle and installing readers on the road. It is to provide a way to control the speed.

Another object of the present invention is to provide a method for detecting illegal driving from driving information and road information of a vehicle.

Another object of the present invention is to provide a method for calculating a toll from driving information and road information of a vehicle.

In order to achieve the above object, the present invention uses RFID, a reader, and a computer. The computer is connected with a storage device for storing road information, vehicle information, driving information and fare information.

As a method of attaching RFID to a vehicle, one RFID can be permanently used for a vehicle by using a method embedded in a license plate.In a place where issuing a pass, such as a highway, the built-in pass is temporarily used. Can be. A separate card-sized RFID can be issued and placed around the windshield of the vehicle for easy reading.

Determine the section of the road you want to speed up or the section where you want to collect the toll. The sections can be repeated continuously and repeatedly. A reader is installed at the start and end of the section so that the RFID installed in the vehicle can be read as the vehicle passes around the reader. When the reader reads the vehicle's RFID, it transmits the reader's ID and time information to the connected computer along with the RFID. The computer stores the information received from the reader in the driving information storage device.

The road information includes distance, speed limit, minimum time, fare and illegal driving information for each section.

When a vehicle passes a section or several sections on the road and needs to check the speed or toll, the computer generates fare information from the driving information and road information stored for the RFID of the vehicle or the toll ticket to determine whether or not it is speeding. Check and issue a penalty notice or settle the toll. The basic calculation method is to read the distance of the corresponding driving section from the road information, take the time from the leader located at the start point and the end point of the section from the driving information, calculate the difference between two times, and calculate the time required in the section. The average speed of the section is calculated by dividing the distance by the required time. If the calculated average speed of the section is faster than the speed limit of the section in the road information,

There is a violation. The toll fare for that section is the fare for that section in the road information.

By installing leaders at various points on the road to track the vehicle's trajectory, illegal driving such as illegal left turns or illegal u-turns can be cracked together. It can know the driving section passed by the vehicle through the sequential combination of the IDs of the readers stored in the driving information storage device for the RFID of the vehicle or the right of passage, and can check whether the driving section is illegal driving section in the road information. have.

Hereinafter, a vehicle speed measuring apparatus according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

First, FIG. 1 shows a vehicle 3 and 7 equipped with RFIDs 5 and 9 and two readers 11 and 13 located at a start point and an end point in a section with a predetermined distance 15 on the road 1. A computer 21 and an information storage device 23 connected to (11, 13) are shown. When the vehicle 3 passes around the reader 11 located at the starting point, the reader 11 reads the RFID 5 and sends information about the read RFID and the ID of the reader and the read time to the computer 21. The information sent from the reader to the computer is as follows.

RFID Reader ID Reading Time

When the vehicle 3 continues to pass through the reader 13 located at the end point, the reader 13 reads the RFID 5 and then reads the RFID and the ID of the reader and information about the read time to the computer 21. send. The type of information sent is as shown above.

The information received from the readers 11 and 13 in the computer 21 is stored in the driving information storage device. The driving information storage stores a large number of information transmitted by various vehicles and from a large number of readers. Among the information stored in the driving information storage device, the result of RFID extracting information such as RFID1 is as follows.

Serial Number RFID Reader ID Time One RFID1 Reader ID1 February 1, 2006 07:00:00 2 RFID1 Reader ID2 February 1, 2006 07:12:00 3

Meanwhile, the road information storage device of the computer 21 stores information for various sections of the road. Road information is stored in the following form. For the convenience of operation, the starting point leader ID and the end point leader ID are combined with hyphens.

Service section Street Speed limit Time fee Illegal operation Reader ID1-Reader ID2 10000 80 7 minute, 30 seconds 1000 Reader ID2-Reader ID3 20000 50 24 minutes 2000

The method of obtaining fare information with reference to the road information of Table 2 using the driving information of the vehicle in which the RFID of Table 1 is RFID1 is as follows. First, in Table 1, the time required for a vehicle having an RFID of RFID1 to pass through a section in which the reader ID is between the reader ID1 and the reader ID2 can be calculated by comparing the times read by the two readers. If you calculate the time taken from 07:10:00 on February 1, 2006 to 07:12:00 on February 1, 2006, the result is 12 minutes. In Table 2, it can be seen that the distance between the leader section ID1-leader ID2 section is 10000m, the speed limit is 80Km / h, the minimum time is 7 minutes 30 seconds, and the fare is 1,000 won, and when the 10000m / 12 minutes is calculated, the average section speed is 50Km / You can get the result of h. If the calculated speed is greater than the speed limit or the time required to pass the section is less than the minimum time, it can be confirmed that there was an overspeed. In the road information in Table 2, the illegal operation content of the driving section leader ID 1-leader ID 2 is copied to the illegal driving column of the driving section leader ID 1-leader ID 2 of the fare information. Rate information summarized these results are shown in Table 3 below.

When the RFID of a vehicle is permanently fixed using a method of embedding RFID in the license plate of the vehicle, the following information is stored in a storage device in which the vehicle information is stored.

RFID the car's number Car type owner Registration Number address RFID1 40405304 Seoul Santa Fe Hong Gil Dong 710101-1820917 100, Gongneung-dong, Seoul RFID2 Seoul 41ga5305 Granger Lee Park 710102-1820917 101, Gongneung-dong, Seoul

By using the vehicle information of Table 4 and the fare information of Table 3, post-payment processing can also be performed using a method of issuing a bill to the vehicle owner. This saves the cost of collecting tolls and makes it easier and faster to handle the collection without disturbing the flow of the vehicle. If the RFID is applied to something like a highway pass, the relationship between the vehicle and the RFID is temporary. When returning the pass, the fare information should be inquired and settled.

2 is a diagram for explaining an embodiment of the present invention through a model of a complicated road close to the actual situation. While FIG. 1 is a road having only one section, the road of FIG. 2 is continuous in many sections. Reference numeral 51 denotes a rest area, and reference numerals 55 to 55 except for the rest area 51 are leaders on the road from right to left of the drawing. The reader IDs of these leaders are referred to as S31 to S55 with S letters in front of them for convenience. Reference numeral 91 denotes a resting place and reference numerals 71 to 95 except for the resting place 91 are leaders on the road from left to right in the drawing. The leader IDs of these leaders are referred to as R71 to R95, respectively, for convenience. All the readers in FIG. 2 are connected to the computer 21. An example of road information according to FIG. 2 is shown in Table 5 below.

When the vehicle having the RFID2 RFID2 passes through the entrance of the reference numeral 101 and exits the exit of the reference numeral 103, the driving information and the fare information will be described. The results of extracting information satisfying the condition that RFID is the same as RFID2 among the driving information collected while the vehicle passes around the readers are as follows.

Serial Number RFID Reader ID Time One RFID2 R75 February 2, 2006 08:00:00 2 RFID2 R77 February 2, 2006 08:12:00 3 RFID2 R79 February 2, 2006 08:12:02 4 RFID2 R81 February 2, 2006 08:17:02 5 RFID2 R83 February 2, 2006 08:17:04

By comparing the driving information of Table 6 with the road information of Table 5 and repeating the calculation in the same way as calculating the fare information of Table 3, the fare information as shown in Table 7 is created. For example, according to Table 6, it takes 12 minutes to pass between the reader IDs R75 and R77. According to Table 5, this section was 20000m and it passed in 12 minutes, so the average speed was 100Km. It can be said that the speed limit exceeded 90Km of this section, which can be confirmed in Table 5, by 10Km.

When the above fare information is created, when the vehicle with RFID2 RFID2 passes through the entrance of reference number 101 and exits the exit of reference number 103, the toll fee of 3007 won is added by adding all the section fees of the sections that passed. You will need to get a penalty notice for speeding.

Let's take another example. When the vehicle with the RFID3 RFID3 enters the road through the entrance of the reference numeral 105 and exits the exit of the reference numeral 107, the operation information and the fare information will be analyzed. Among the driving information collected as the vehicle passes around the readers, RFID extracts information such as RFID3 as shown in Table 8 below.

Serial Number RFID Reader ID Time One RFID3 R79 February 3, 2006 09:00:00 2 RFID3 R81 February 3, 2006 09:07:30 3 RFID3 S41 February 3, 2006 09:07:34 4 RFID3 S39 February 3, 2006 09:19:34

When the operation information of Table 8 is compared with the road information of Table 5 and the calculation is repeated in the same way as the calculation of the fare information of Table 3, the fare information as shown in Table 9 is created. For example, according to Table 5, the operating section R81-S41 has an illegal operation category called U-turn prohibition. When creating fare information, illegal driving items of road information are copied as illegal driving items of fare information.

When the above fare information is created, when a vehicle with RFID3 RFID3 enters the road through the entrance of the reference numeral 105 and exits the exit of the reference numeral 107, the toll fee of 3005 won is added by adding all the fare to the passage. You will receive a penalty notice for illegal operation that violates speeding and U-turn prohibitions.

Let's take another example. When the vehicle with the RFID4 RFID4 enters the road through the entrance of reference numeral 109 and exits the exit of the reference numeral 111, the operation information and the fare information will be analyzed. Among the driving information collected as the vehicle passes around the readers, RFID extracts information such as RFID4 as shown in Table 10 below.

Serial Number RFID Reader ID Time One RFID4 S43 February 4, 2006 10:00:00 2 RFID4 R87 February 4, 2006 10:00:04 3 RFID4 R89 February 4, 2006 10:07:34 4 RFID4 R93 February 4, 2006 11:07:34 5 RFID4 R95 February 4, 2006 11:13:34

When the operation information of Table 10 is compared with the road information of Table 5 and the calculation is repeated in the same way as the calculation of the fare information of Table 3, the fare information shown in Table 11 is created. For example, according to Table 5, the driving section S43-R87 has an illegal operation item of prohibiting left turn. When creating fare information, illegal driving items of road information are copied as illegal driving items of fare information.

RFID Service section Speed Section Fee Speeding Illegal operation RFID4 S43-R87 45 5 Prohibit left turn RFID4 R87-R89 80 1000 RFID4 R89-R93 10 1000 RFID4 R93-R95 120 1000 30

When the above fare information is prepared, when a vehicle with RFID4 is RFID4 enters the road through the entrance of reference numeral 109 and exits the exit of reference numeral 111, the toll fee of 3005 won is added by adding all the toll zone passes. You will receive a penalty notice for illegal driving that violates speeding and left turn prohibitions. The resting time in the section where the rest area 91 is located does not affect the speed measurement in the next section.

Through the above description, the vehicle speed measuring apparatus according to the present invention calculates an average speed for each section for a plurality of driving sections that are set on the road and checks whether the speed limit set for each section is kept or exceeded. It showed that the speeding can be controlled. The speed regulation according to the present invention is expected to be effective in preventing overspeed since it is possible to determine whether or not overspeed is achieved with an average speed in one section rather than whether overspeed is at one point. It has also been shown to detect illegal driving on driving routes, such as non-turning off violations or non-turning offenses, and it is also possible to calculate and collect tolls.

As described above, the vehicle speed measuring apparatus according to the present invention will be able to save the cost required for speed regulation and achieve a certain effect compared to the existing speed camera.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the technical spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification but should be defined by the claims.
