Abstract

Automated car-park management system, capable of managing many car-park areas (1,2,3), in which each car-park area is equipped with an automatic till, with an entry gate and an exit gate with cameras for taking the number plate of a vehicle on its way in and out respectively, communicating via internet with a remote control center (10) to which the number plate images taken and a number plate code punched in by the user at the automatic till are sent. The control centre (10) takes care of the recognition of number plates, from the respective images, and verifies that for a vehicle on its way out the payment due has been made comparing the number plate code punched in by the user with the number plate recognised. The system lends itself, without constructive complications, to the association of a secret code (PID) with the number plate and with a multiplicity of auxiliary services like reservations, prepayments or other, also from a different location, reducing to the minimum the complexity and the cost of the fixed investments in the car-park areas and the relative running costs. <IMAGE>

Description

The The present invention relates to an automatic parking lot management system. It is known that conventional Parking, which are managed by service personnel, increasingly by non-guarded ones parking be replaced with automatic or semi-automatic management, whose running costs are much lower and they are also uninterrupted Can be operated 24 hours a day.

in the Essentially, automatic parking is provided to allow access attained to a closed parking area via an entrance, equipped with a movable barrier.

At the Entrance is as well a ticket issuing device is provided which detects the presence automatically detected by a vehicle, or when a button is pressed, gives the user an entry ticket at which the entry time which is recorded on a magnetic strip or printed with codes that are read optically or magnetically can. The opening the barrier hangs from removing the ticket from the output device, which is through the user is running becomes.

Around To leave the car park, the user must first pay taken care of at an automatic till or at a pay booth, where the ticket is read, generally automatically, to the invoice amount due to calculate. When the payment is made, the approved Starting time automatically registered and the ticket to the user returned.

At the Exit of the parking area becomes a movable tax barrier by introducing the ticket in an automatic reading device only opened, which, if this determines the legal starting time and the pay placed was ordered to open the barrier.

systems of this kind have different limits: there are costs related with the consumables (tickets with a magnetic stripe and Like.), The delivery must be carried out periodically.

The Issue of the ticket and its removal by the user brings a relative delay the entry operations and a certain inconvenience to the user with himself who is obliged to open the vehicle window and to close. The same disadvantages exist at the output.

Finally is the level of security is very low and theft and confusing of automobiles can not be excluded.

In the US 5 638 302 In order to at least partially avoid these disadvantages, it has been proposed to add a camera to a parking lot entry gate in addition to the conventional ticket dispenser to read the license plate of an entering vehicle and possibly other features such as the vehicle length.

One Data processing system which is suitably programmed is for the Number plate recognition and storage provided, together with a corresponding code or number of the issued Tickets.

When Alternatively, or at the same time, the data representing the Identify vehicle to be recorded on the ticket.

At the Output of the parking area are a ticket reader and a Camera also available, the camera being the vehicle detection supplies.

The read information is compared with an information which stored on the ticket and / or recorded, and the exit gate will only be opened in case of an information match. in the Case of a mismatch be alarm systems for signaling and intervention of public or private surveillance services activated.

The Inconvenience for the user is not avoided, the operating costs associated with the ticket issue will not be eliminated, and also the input / output operation is not accelerated.

Next These disadvantages are limited by number plate recognition: for a good reliability To gain recognition, it is necessary to be more complex with certain Software equipped to be able to, only in powerful data processing systems to be effective. These funds are therefore expensive, and every parking lot must be equipped with these means be.

For example, the teaches US 4 603 390 a computerized parking system capable of determining the time of entry and exit of a vehicle and the time how long a vehicle has remained in the parking area. The due parking fee for each vehicle is calculated on the basis of a predetermined rate or rates, and the time in which the particular driving remained in the parking area. In addition, the teaches US Pat. No. 6,340,935 a computerized parking management system that is capable of identifying the particular vehicle parked in any parking space of a parking lot area. The system provides a computer search facility to locate vehicles within the parking facility.

The present invention overcomes these disadvantages and provides an automated parking management system having the following advantages:
Simplification of user operations;
Speed of entry and exit operations, which avoids the formation of snakes;
Reduction of fixed investment costs and administrative costs;
Elimination of consumables costs;
Simplification of local administration and control units;
remote, simple and centralized control of many parking areas via the Internet, with the possibility of offering additional services, such as reservation, subscription, prior payment management and other ancillary services;
Possibility - also by selection - which secret identification code (PID) is associated with each license plate at a simple request of the user and thus reducing the risk of theft and illegal exit of the vehicle to the minimum.

The Invention is independent in the Defended claim 1.

The Features and advantages of the invention will become apparent from the following Description of a preferred embodiment more clearly, which with reference to the attached Drawings are given, in which:

10 Fig. 10 is a flow chart of operations performed by a remote control center of the system to control an exit gate.

According to 1 the system has several local resources 1 . 2 . 3 which are respectively allocated for the plural parking lot areas of parking lot 1, parking lot 2, parking lot 3, and are arranged thereon in communication via the Internet by means of high-speed transmission links 5 . 6 . 7 . 8th . 9 (optical fibers, ADSL and others) with a central administration 10 and a person-equipped monitoring center 11 ,

In the central administration 10 All the processing and control operations necessary for the management of various parking lots that are more than one in number and that do not necessarily belong to the same company are performed.

In other words, the central administration 10 provide a legal and administratively autonomous source whose functions are offered as a service to multiple users.

As a centralized means, the central administration 10 whose investment and running costs are thus spread over several parking spaces, consist of many high-performance computers or "servers" and large storage facilities that are able to cope with all the necessary image recognition and data storage operations, as well as necessary "buffers" of funds for provide the case of malfunction of some of the units that make them up.

In the same way, the local resources and central administration communicate with the Operations Monitoring Center via the Internet 11 where qualified personnel is able to work with the Be Communicating users of parking spaces to solve problems and emergencies, as well as arranging interventions by staff in different parking lots, if necessary.

2 is a block diagram of the structure of the local parking tools that make up the system:
Each parking lot has one or more automated entry gates 12 , one or more automatic cash registers 13 and one or more automatic exit gates 14 intended.

Of the Construction of these units will be described in more detail in the following figures shown.

The blocks 12 . 13 . 14 are equipped with an IP connection interface (Internet protocol interface), which these via a network node 15 and a high speed communication communication channel 16 in conjunction with both the remote control center 10 ( 1 ) as well as the Operations Monitoring Center 11 combines.

3 shows the structure of an entrance gate 12 from 2 in more detail.

The entrance gate points to:
of course a conventional mobile barrier 17 .
a first facility 18 for determining the presence of a vehicle which is located immediately upstream of the barrier and is conventional per se (variable reluctance coil),
a second device 29 for determining the presence of a vehicle immediately downstream of the barrier 17 arranged, which is also common
a high-resolution camera 19 for example, a CCD digital camera with 1200 × 800 more pixels, for picking up the rear license plate of a vehicle which is upstream of the barrier 17 is positioned, and
a data collection and command system 21 with a microprocessor, a random access memory and an input / output interface with IP protocol for communication with the remote control center 10 ,

Preferably, the entrance gate is also provided with a display device 22 equipped to indicate to the user the status of the parking lot, whether it has seats or is occupied, or is only open to subscribers, or for reserved seats.

These Information is passed through without the need for local processing provided the remote control center, which according to the capacity of the parking garage the number of vehicles that are retracted or extended are and the possible ones Reservations or subscriptions in the case of pre-defined time bands local status of the parking area can determine.

The input gate operates essentially as a data collector, without any particular processing load, for example according to the flowchart of FIG 6 , If a permission (permission) is given that vehicles are let in, (block 40 : set parking status, find 18 if free) if this from the facility 18 receives a signal indicating the presence of a vehicle (blocks 41 : Discovery 18 Enabled?), This activates the camera 19 to read the license plate and deliver the image to the control block (block 42 : License plate image and delivery), without any processing, away from possible compression.

When the status of the parking lot is free (block 43 : free), depending on the condition that no vehicle is present downstream of the barrier (block 44 : Detection 20 activated?), Causes the barrier to open (block 45 : open 17), and it is returned to monitor the presence of vehicles on their way inward (Block 41 ) after previously verifying the passage of the vehicle in the area downstream of the barrier (block 50 : Determination 20 is activated), and after the barrier has been closed again, the management and the control center is confirmed that the vehicle has actually entered (block 51 : close 18 and confirm).

If the parking space is available only for reservations or subscriptions, the data collection system continues to run from the block 43 to wait for approval to open the barrier (block 46 : allowed?), and should this be received, it will continue to open, as already shown.

In the opposite case (an answer is needed in any case to avoid a dead point of the river) this commands the display device (block 47 : Indication) to indicate that entry is not permitted and after verifying that the vehicle has cleared the entrance area (Block 48 ), it resets the states of the display device (block 49 ) and begins again to monitor the presence of new vehicles coming in.

Therefore are for these operations minimal and cheap means at the entrance gate necessary, and there is no need for ticket dispensers with related times, printers or magnetic tape recorders.

In particular, the access is particularly fast and does not indicate the discomfort of the Users to withdraw the entrance ticket and to open and close the vehicle window.

If the parking lot or the parking garage has free areas, the hangs Entry time only from the practical execution of the areas immediately downstream of the Tors and is therefore reduced to a few seconds, i. immediate on the time necessary to stop the vehicle, reading (not the recognition) of the license plate and continue to drive.

If the inlet is dependent on the approval of the remote control center, is due to the speed of data transfer processing the rapidity of entering no significant reduction subjected.

4 shows the structure of an automatic cash register 13 from 2 in more detail. The automatic cash register may be used directly by the user for various operations, such as paying for a one-time stay, subscribing and pre-paying for periodic or specific stays, pre-paid reservation and, in particular, identifying the vehicle in relation to a secret PID code in addition to the license plate data.

In terms of these functions and more that can be seen in the future, the automatic cash register, which works simply as a terminal without special processing tasks, includes:
a TS data entry keyboard 23 possibly a touch-sensitive screen (TS) used to input license plate information, to input a possible PID code of the requested service type of operation or other information necessary from time to time;
a possible display device 24 to show information if not already through the touch display screen 23 educated;
a bill detection and handling device 25 .
a coin detection and handling device ( 26 ) with possible change in return,
a credit and debit card recognition and handling device 27 ;
a contactless card reading / writing device according to the ISO 14443 standard for payments using a resident's card,
a receipt printer 28 which is activated only by user's requirements;
an intercom ( 29 ) to communicate with the Operations Monitoring Center, if necessary
a possible control TV camera 30 ;
an electronic logic 31 for controlling the automatic cash register with a microprocessor, a memory and related application software for managing the payment operations and the interface with the users in general.
a connection interface 32 (IP) via the Internet with the remote control center and the Operations Monitoring Center.

• 1) Zuordnen eines PID-Codes mit den Nummernschilddaten: der Benutzer, der sich selbst gegenüber Diebstahl oder Verwechseln des Fahrzeugs zu schützen wünscht, unmittelbar, nachdem er sein Fahrzeug (oder sogar vorher) geparkt hat, geht zur automatischen Kasse und wählt unter Verwendung der Tastatur die PID-Funktion, gibt die Nummer des Nummernschilds und danach den Geheim-PID-Code ein.

All these elements are known per se and require no explanation. It is only necessary to note that the electronic logic must perform elementary interface functions, with the complex processing functions requiring access to data files to be executed by the central office. The basic operations required by the user at the automatic till are two:

• 1) associating a PID code with the license plate data: the user who wishes to protect himself against theft or confusion of the vehicle immediately after having parked his vehicle (or even before) goes to the automatic cash register and dials using the Keyboard the PID function, enters the license plate number and then the secret PID code.

The Information is then delivered to the remote control center and through this manages. A time limit may be provided by the Moment when the vehicle enters the parking lot to this operation perform, which are overcome with more complex procedures and with the intervention of the company central administration may be at risk of non-accurate allocation of PID codes for vehicles, who have none to reduce to a minimum. The linking of the PID code is for the user of course optional.

On the same way in experiments with subsequent allocation of a PID code for the same Vehicle the subsequent operations of identification of the user be assigned over Network camcorder, intercom or other suitable instruments (credit card, Identity cards that can be read automatically and the like.).

With the same security procedures commonly used in Internet transactions In addition, the user can use the automatic connection request a PID code with the license plate of the vehicle, in a permanent or semi-permanent way, even if he does not currently park, so as to avoid the burden of a PID to associate with the license plate every time he parks in an area managed by the same system.

• 2) Ermächtigung für das Fahrzeug, auszufahren, in Abhängigkeit von möglicher Bezahlung: der Benutzer, der beabsichtigt, mit seinem Fahrzeug vom Parkplatz herauszufahren, geht zur automatischen Kasse und wählt unter Verwendung der Tastatur die Ausfahrtfunktion aus, und gibt das Nummernschild und den möglichen PID-Code ein.

In this case, the connection of the PID code to the vehicle after the first time can be automatically performed by the remote control center upon detection of the license plate.

• 2) Authorization for the vehicle to drive out depending on possible payment: the user intending to drive his car out of the parking lot goes to the automatic cash register and selects the exit function using the keyboard and gives the license plate and the possible PID Code.

The Information is delivered to the remote control center and through this manages that if the vehicle and the specific conditions be recognized (subscription, pre-payment reservation by third parties or others), and the time spent in the parking garage was spent, if the parking costs are timely, on the display device the authorization to go out or previously requirement for payment in banknotes, coins or further confirms what authorization granted becomes. After this point, the user has nothing further to offer do as his vehicle to drive to the exit (within a certain Time limit), where the vehicle is recognized and authorized, with the opening the barrier and without further formalities.

5 shows in the same way as 3 the construction of an exit gate 14 from 2 in more detail.

The exit gate points to:
a first and a second very frequently opening vehicle barrier, which are installed in the manner of a cage;
a first facility 35 to detect the presence of a vehicle, which is upstream of the first barrier 33 is available;
a second device 36 to detect the presence of a vehicle in the cage;
a camera 37 to read the license plate,
an intercom 38 (SOS) for communication with the Operations Monitoring Center 11 ( 1 ), and
a collection and command system 39 with a microprocessor, RAM memory and a connection interface with IP protocol for exchanging signals (data or information) over the Internet with the remote control center and the operations monitoring center.

The output gate operates essentially as a data collector / transmitter, without any special processing load, according to the flowchart of FIG 7 : it receives from the institution 35 a signal indicating the presence of a vehicle (block 52 : Detection 35 activated?), Leaves the barrier 33 open (block 54 : Opening 33) in the condition where a vehicle is not already in the cage (block 53 : Discovery 36 Enabled?), Received by the facility 36 a signal indicating the presence of a vehicle (block 55 ), in turn closes the barrier 33 , activates the camera 37 for reading the license plate and, without any processing away from possible compression, transmits an image that was taken to the remote control center (Block 56 : Close 33-license plate image and send) and after receiving a warrant signal from the remote control center (Block 57 : authorized?) it opens the second exit gate 34 (Block 58 : open 34). Finally, after verifying that the vehicle has left the cage (Block 59 : Detection 36 activated?), It in turn closes the barrier 34 (Block 60 : close 34) and returns to the initial monitoring state of the area upstream of the first gate.

In the case where authorization to drive out is not received, the collection system places itself in an inactive state: it is the task of the operations monitoring center in cooperation with the remote control center to solve the problem around the barrier 34 after all necessary security procedures have been performed and thus complete the process. To facilitate the task, the system can use the intercom 38 ( 5 ) which connects the user directly to the monitoring center.

All operations of license plate recognition, verification of completed payment (or the existence of forms of subscription or other special conditions) and the extension time are transmitted to the remote control center, which in the event of a circumstance, if it occurs requiring intervention by an operator, the intercom 38 and the exit gate is placed in communication with the monitoring center.

Therefore At the exit gate are minimal and inexpensive data processing means necessary, which can be more than one, without significant investment costs, to avoid interruptions of the exiting traffic in the case where a vehicle tries to drive out without authorization.

Besides that is Under normal conditions, access to the gate is particularly fast and brings no inconvenience to the user.

The basic data processing means for managing and controlling the system are essentially on the processing and the control center 10 concentrated ( 1 ), where only servers are provided for reasons of efficiency and working speed, which are specially designed and specialized in programs for executing them.

One first server named ANPR is for managing the functions automatic recognition of license plates and recording the related pictures in suitable files.

A Ordinal number and a code (or codes in case of ambiguity in recognition) representing the recognized license plate brought in conjunction with every recorded image so in to be able to be quickly tracked down in the file, in case of need.

It is possible, too, the date and the entry / exit time in / from the parking lot to connect the picture with the date, time of extension and a parking code to download to a collection archive, if the Exit from the parking lot is detected.

A second server named PARK-SERVER is intended especially for park space-specific functions or those that differ from different managed parking spaces, for example:
Recording entry / exit crossings and therefore real-time identification of the available / full status of the parking lot;
Recording payments
Recording and administration of the secret code (PID) in connection with the number plates;
Forming an interface with local admission / exit pass authorizations, activating the payment procedures for updating and managing the status of the parking areas, and determining alarms and emergencies. A third server, referred to as an application server, essentially performs the helper application functions that can be accessed through a web browser that can be grouped together in the following ways:
Auxiliary reception functions for the manual correction of the license plate in the exceptional case of an error or difficulty in the automatic recognition process, which can not be overcome with criteria of data redundancy (in this case, the license plate image is shown to the person-equipped monitoring center) to the barriers in Case of need to open / close to assist the user in difficulty and the like;
Administrative functions, such as definition of prices, possible opening hours of the parking lot, issuing of subscription, calculation and completion of payments according to the approved procedures, acceptance of reservation by third parties, for example hotels and the like;
billing and statistical reporting capabilities.

Of course they lead three servers perform the different tasks in one integrated Wise way of working together and with each other while exercising their communicate specific tasks.

Without entering into a detailed description of different processes performed by the control center, they are 8th . 9 . 10 Flowcharts, merely exemplary, which may be subject to many variations, showing the three most common processes being performed.

8th : Administration of the driveways

The process is activated when an entry gate sends the image of a license plate and a vehicle parking space code to the control center (Block 61 : License plate image and parking lot number). The code is needed to identify the parking lot, in which case many parking lots are managed by the same control center.

The control center, in particular the ANPR server, recognizes the license plate and forwards it to the parking server (block 62 : Detection; Sending to the park server).

The park server verifies the status of the parking lot (block 63 : Park status).

If the parking lot is free, it will continue immediately to wait for confirmation from the entrance gate, that the vehicle that is traveling, is currently driven through. When the confirmation is received (block 67 : confirmed), the number plate is stored in a vehicle list, which is present in the parking garage, and brought in connection with the entry time (block 68 : save number plate with time).

Of the ANPR server also saves the overall picture.

If the parking space is only available for reserved seats (reservations and subscriptions), the procedure continues from the block 63 to the block 64 and the park server verifies that License plate of the vehicle is present in a list of subscribed or reserved number plates.

In the affirmative case, this authorization sends to the entrance gate to open it (block 65 : send approval) and continue to the block 67 ,

In the negative case this sends the denial of authorization to the entrance gate and the process is terminated (block 66 : Sending no; The End).

In the output signal from the block 68 verifies the parking server, if it is necessary to update the status of the parking, due to the entrance of another vehicle (block 69 : Parking status change?), And in the affirmative case the change of status is communicated to the entry gate (or the gates, if there is more than one) (block 70 : send change). At this point, the process ends.

9 : Administration of the automatic cash register

The process is activated with transmission to the control center by an automatic cash register of a license plate code, a function code, a cash register code and a parking code, and, if necessary, a secret code (PID) (block 71 ).

According to the function that is required (block 72 : Function?) The process is executed over many lines.

If the required function is PID, ie the connection of the secret code with the license plate, the control center connects (block 73 : refer to PID on license plate) the PID with the number plate already stored, if necessary, and assigns them, as already stated, in relation to a time limit and on the verification that a PID has not yet been assigned to the same vehicle. After that, the process ends.

If the basic conditions are ignored, the Process in a different way that is not worth showing to become.

If the required function is "exit", ie the authorization to extend, the parking server (compare with data file) compares the license plate and the possible PID with the vehicle list (and the relative PID's) present in the car park calculates the Invoice amount in relation to the time spent in the parking garage (calculated amount), updates the settlement of possible payments in advance or shows the amount to be paid to the cashier (send payment information) (block 74 ).

When a payment is due, it waits for confirmation from the cashier that the payment has been made (Block 75 : Payment OK?), And when it has been received, it sends a confirmation to the cashier that the transaction has been completed (Block 76 : Confirmation) and connects the authorized exit time with the license plate in the existing vehicle list (Block 77 : relate extension time on number plate).

If the PID opposite that is different, that may be communicating with the license plate, or when paying not done was, more complex procedures are activated to the correction of the possible Allow mistakes, enforce the payment and in extreme cases the authorization to deny, to drive out and to alert the operations monitoring center.

For more features that may be required (block 72 : others), there is no point to develop here a detailed analysis of several different procedures that could be activated.

10 : Management of the exit gate

The process is activated upon receipt of the license plate image and parking lot code, which are delivered through the exit gate (block 78 : License plate image and parking lot number).

The ANPR server manages the recognition of the license plate and the transmission of the license plate code to the parking server (Block 79 : Detection; Send to parking server).

This is also stored in memory for possible future use (block 80 : save).

The parking server compares the license plate code with the list of vehicles present in the parking garage (block 81 : compare with data file) and verifies the authorized exit time of the vehicle.

If the vehicle is allowed to drive out (block 82 : Exit allowed), this sends an authorization to the exit gate to open the gate (block 83 : send authorization). Otherwise, it activates an interactive communication procedure between the exit gate and the operations monitoring center (Block 84 : start interactive procedure - alert monitoring center).

With the approval provided, it sends this, if necessary, to update the status of the car park (block 85 : Status change?), And upon confirmation sends this to the input gates the relevant information (block 86 : send change). After that, the process ends.

It It will be understood that the flowcharts shown are examples are specified, and that many variants can be introduced.

In In any case, these show that all data processing and license plate image recognition functions are focused on the remote control center, reducing the tasks the local Units (goals and coffers) are reduced to a minimum.

Besides that is it is clear that the interconnection of local units with the Control center over Internet allows the control center to communicate with all over the Internet Users of the network from anywhere on the network. It is thus possible to subscribe, make parking reservations and availability to consider, from any location and thus an optimal evaluation of the funds to give, with maximum comfort for the user.

If considering this, one can observe that it is possible to offer the user more favorable parking conditions in the event that when he enters or even before, he defines the anticipated parking time (whose Work can also be performed at the automatic cash register) and that before fixed time limit respected.

This indeed allows more effective planning of the use of funds.

Besides that is it in addition to the local automatic cash registers or their replacement possible, the Cash register service or simply the extension registration service with the integrate, which is already provided in supermarkets or department stores This is where many benefit from using private parking areas where it is necessary to use a parking ticket to show which issued by an automatic distribution system and to get it stamped at the box office Exit permit.
