The present invention is a parking lot access control system, in particular a parking lot system that automatically recognizes license plates.

In recent years, the traffic volume in various regions of Taiwan has been increasing year by year. Especially in the holiday season, the traffic volume in the metropolitan areas of various counties and cities is extremely large, which causes various problems such as difficult traffic control. In addition, the number of parking spaces on the street in the metropolitan area is limited. It is hard to find a parking space in the metropolitan area. To this end, the demand for large-scale flat parking lots is increasing day by day, and even to compensate for the narrow areas of the available areas in the metropolitan area, the construction of such buildings in the three-dimensional parking lot has been continuously increased, which has solved the problem of insufficient parking spaces in the metropolitan area.

However, in order to solve the problem of insufficient parking spaces, the owners of parking lots are faced with the problem of parking lot management to be solved in today's traditional parking lots, large parking lots and even the latest three-dimensional parking lots. In particular, how to automatically and correctly identify each entering and leaving vehicle by the parking system in the shortest time is a problem to be overcome. Therefore, in a unit of time, a large number of parking spaces and vehicle rotations are constantly being carried out in the parking lot, which becomes a management problem for the parking lot owners to bear the brunt.

In the past, the traditional type of toll parking lot was controlled by the ticket card, which caused the user's inconvenience in saving the ticket card and increased the management procedures of the owner. However, this relies heavily on the manual parking lot management, and the efficiency and cost of the parking lot operation. It is a burden. In view of this, a new generation of ticketless card-type parking lot management system was born, and all the entry and payment materials of all certified vehicles were entered into the computer database to fully manage the parking lot. Today, the method of vehicle certification has been developed to use image capture devices, such as cameras, cameras, etc., with back-end computing processing equipment, such as computer and server image recognition technology, first to the vehicle license plate Capture and identify the vehicle's license plate number for vehicle certification before placing the vehicle into or through.

Although the correct recognition rate of license plate image recognition has reached more than 90%, if the image capture is unclear, the target moves and the license plate is stained with sludge, water marks or the body structure and numbers near the license plate are similar, As a result, the identification of the car number could not be completed, or the car number was incorrectly identified, which caused the trouble of the vehicle statistics in the parking lot, and caused the omission of the charge. These problems caused by the identification of license plate images require human resources, so it is impossible to save labor costs.

Thanks to the rapid advancement of technology, the applicant further designed to capture the license plate image of the vehicle, and then identify the vehicle license plate number, as well as the commonly used electronic sensor tags on the current vehicles, such as: eTag, NFC ( Near Field Communication (NFC), etc., identifies the vehicle by Radio Frequency Identification (RFID) and combines it with the original license plate image recognition technology to make up for the failure to identify or misidentify the original license plate image. This is caused by the blockage of traffic at the entrance and exit of the parking lot and the delay of the passage time; in other words, the dual authentication technology combining image recognition and electronic induction tag is applied to the vehicle access control of the parking lot, which improves the success rate and correctness of vehicle identification. And does not sacrifice the speed of the vehicle at the entrance and exit of the parking lot. Therefore, in the modern information parking lot, it is the problem to be solved in this application to achieve operational efficiency and save labor costs.

Therefore, the object of the present invention is to provide a vehicle entry and exit parking control system combining electronic tags and image recognition technology, which can be applied to a parking lot having an entrance and an exit. The entrance of the parking lot is provided with: an in-vehicle sensing device for sensing whether a vehicle intends to enter the entrance; an entrance image capturing device for capturing license plate image data of a vehicle intended to enter the entrance; an entrance electronic tag reading A device for reading electronic tag data of a vehicle that intends to enter the entrance; an inlet blocking device for entering the vehicle that controls the entrance.

The vehicle entry and exit parking control system further includes: a central processing unit for processing electronic tag data of a vehicle, and identifying the license plate image data, and recording the entry time and playing time of the vehicle; and a database for storing a vehicle. Electronic label information, license plate number, admission time and playing time. The central processing unit can instantly identify the license plate image data and obtain the corresponding recognized license plate number, and at the same time, receive the electronic label data transmitted by the inlet or outlet electronic label reading device, and use the electronic label data as The key value is queried in the database to check whether there is a license plate number corresponding to the electronic label data. If the license plate number corresponding to the electronic label data is queried, the corresponding license plate number is read out and associated with the electronic label data, and stored in the corresponding field in the database; The license plate number corresponding to the electronic label data stores the previously recognized license plate number and the electronic label data stored in the corresponding column in the foregoing database.

According to the information related to the electronic label and the license plate number in the database, the corresponding data is recorded corresponding to the entry time and the calculation of the parking fee, and the parking fee is charged, and the charging information is transmitted to the central processor for charging. And when the central processor identifies the vehicle license plate number of the charged fee through the associated data in the database, instructing the outlet blocking device to move to the designated position by the blocking position blocking the outlet.

Therefore, the present invention is a vehicle entry and exit parking control system system combining electronic tags and image recognition technology, providing license plate image recognition as a vehicle certification, and also executing corresponding license plate number data in the database according to the electronic tag of the vehicle. Carry out vehicle identification and control to reduce the labor cost and automatically identify the error rate of license plate images.

As shown in the first figure, the present invention is a vehicle entry and exit parking control system combining electronic tags and image recognition technology. When the vehicle 6 arrives at the parking lot and touches the outside vehicle sensing device 106, the vehicle image 6 can be sensed by the entrance image capturing device 104 disposed at a high place to look at the license plate image. At the same time, the electronic tag data of the vehicle 6 is read by the ingress electronic tag reading device 105. At this time, if the license plate has been successfully recognized and the electronic tag has been read, the inlet blocking device 103 is moved from the blocking position 101 to the admission position 102, and the passage is made to pass to the vehicle 6. When the vehicle 6 is in contact with the inboard sensing device 106, the representative body has fully entered the parking lot and the inlet blocking device 103 is moved back to the blocking position 101 by the access position 102.

In addition, as shown in the second figure, it is a structural diagram of a parking lot entrance. First, the license image capturing device 104 captures a license plate image of a vehicle, and then transmits it to the central processing unit 3 to recognize the license plate, and is also read by the entrance electronic tag. The taking device 105 reads the electronic tag data of the vehicle 6 and transmits it to the central processing unit 3 to query the corresponding license plate number data in the database 4, and finally records the electronic tag data, the license plate number data and the admission time of the vehicle 6 to the database 4 Then, the central processing unit 3 directs the entrance blocking device 103 to release.

As shown in the third figure, the flow chart of the license plate number and electronic label data is linked. In step 701, when the car arrives, in step 702, the central processing unit 3 can instantly recognize the license plate image data and obtain the corresponding recognized license plate number. At the same time, the electronic tag data sent by the ingress electronic tag reading device 105 or the e-mail tag reading device 205 can be received, and in step 703, the electronic tag data is used as a key value, and the data is searched in the database 4 Is there a license plate number corresponding to the electronic label data? If the license plate number corresponding to the electronic tag data is queried, step 704 is executed, the corresponding license plate number is read out and associated with the electronic tag data, and stored in the corresponding field in the database 4; If the license plate number corresponding to the electronic label data is not found, step 705 is executed to store the identified license plate number and the electronic label data stored in the corresponding field in the database.

As shown in the fourth and fifth figures, when the vehicle 6 wants to leave the parking lot and touches the inner exit sensing device 206, the vehicle image is captured by an exit image located farther from the height of the field of view. The device 204 performs the license plate image capture, and at the same time, reads the electronic tag data of the vehicle 6 by the exit electronic tag reading device 205, and the central processor 3 and the billing device 5 confirm that the vehicle 6 has completed the payment. The outlet blocking device 203 is commanded by the central processing unit 3 to move the lever from the blocking position 201 to the designated position 202, and the open vehicle 6 is allowed to pass. When the contact of the vehicle 6 with the outboard vehicle sensing device 206 ends, indicating that the vehicle body has left the exit, the outlet blocking device 203 will be moved back to the blocking position 201 by the designated position 202.

As shown in the sixth embodiment, in the second embodiment of the present invention, a set of switching devices 31 are provided for elastic selection. The switching device 31 is disposed at the inlet 1 and is coupled to the central processing unit 3, respectively. Once the central processing unit 3 cannot interpret the license plate image taken by the portal image capturing device 104, in the case of the vehicle entering the vehicle, the switching device 31 can be manually controlled to instruct the central processing unit 3 to turn on/off the inlet blocking device 103. When the sudden situation causes the user to be inconvenient, the switching device 31 can artificially judge the car park involved in the automatic operation. For example, when the identification fails repeatedly, the operator can set whether the system is released according to the situation. If it belongs to the parking lot of the monthly fee parking lot, the member-made parking lot, the resident parking lot, etc., each parking space has a specific number. If it is unrecognizable, it is very likely that it will not be qualified. Therefore, the system can directly reject the vehicle and ask the owner to contact the customer service. . If it is confirmed as a company customer, it can be directly released by the switching device 31. In general parking lots, it is possible to decide whether to release according to the time slot or the vacancy rate in the field. In the peak period, if the system is unrecognizable, the operator can set it to be released directly so as not to hinder the subsequent traffic flow; otherwise, it will not be released. The vacancy rate is high, and the operator can also set direct release; if the vacancy is limited, only the system identifiable will pass. Of course, if the industry does not want to miss the opportunity of charging for any parking space, anyone who identifies the bad can be blocked. First identify the post-release, switch device and other settings, giving the operator an additional choice.

As shown in the seventh figure, the parking lot of the third embodiment of the present invention is provided with a blocking device 82. The general purpose of the blocking device 82 is to ensure that the owner has paid the fee, and the paid parking fee is allowed to move the vehicle. The existing parking lot often encounters the problem of occupying the parking space. It is nothing more than the general people occupying the disabled parking space, the exclusive parking space is used by others, and the parking space for unloading is occupied for a long period of time. In this case, combined with the image capture and license plate recognition function of the present invention, an exclusive protection parking space is achieved. Structure Relationship As shown in the seventh figure, the portal image capturing device 104 detects the vehicle 6 or captures the license plate, and the central processor 3 knows the identification result of the license plate. If the license plate belongs to a specific user such as the above-mentioned disabled person, exclusive customer, unloading truck, etc., the entrance blocking device 103 is notified to release, and the blocking device 82 for protecting the specific parking space 81 is instructed to remove the barrier so that the specific user enters the corresponding parking space. 81.

In addition, as shown in the eighth figure, a schematic diagram of the barrier device of the present embodiment is shown.
