Description

The invention relates to the field of regulation of the movement of road transport and, in particular, to the regulation of car parks involving tolls.

The closest in technical essence - the prototype - is a car park with a large number of parking spaces for cars that have shields for attaching license plates with optically readable car license plates and on-board devices with radio-readable radio identifications, characterized by a central computer for storing reservation of a parking space from parking spaces, car license plates and intended radio identifications common to parking spaces with a radio beacon n and at the entrance of a car park for reading through a radio identification of an incoming car and a message to a central computer, and for each parking space, respectively, with said device for communicating an optically readable car license plate of a car parked thereon to a central computer, the central computer being configured to check whether then by filming the installation of this parking space to the radio recognition communicated to him by a car license plate, respectively which is stored in the reserved reservation of the parking space, and if there is no recording of this, an additional filming unit was mounted at the entrance for optical reading of the car's license plate number of the incoming car and messages to the central computer, the central computer being configured to check whether the messages communicated to each other in the reservation of the parking space radio recognition and car license plate communicated by an additional filming installation, and if not, recording this, adiomayak DSRC-represented beacon for reading via radio from the vehicle devices DSRC-toll road system (see. RU 2013142281 cl. G08G 1/14).

The known solution can be described as a closed parking zone and has the following disadvantages. A well-known solution requires dual control of vehicles at the entrance / exit of parking using on-board devices of the DSRC-paid road system and directly at the parking space by analyzing the video image of the front plate for attaching the car license plate, the DSRC system for localization, vehicle identification and charging cannot be used in open areas that exclude the presence of fences, since the use of only a DSRC system in each parking space makes the system design zbytochno complex and expensive, unreliable and uneconomic.

Another drawback is the consequence of using a video surveillance system with a lighting unit to solve the problem of localization, identification and verification of vehicles directly at a parking space as an additional identification system. Video surveillance tools provide automatic recognition of numbers and have common limitations for such systems, namely: the recognition probability is less than 100%; the need for image transmission from each of the sensors; the need for cleaning optical sensors and lighting devices.

The lack of means of informing the correct parking creates an obstacle to neighboring cars.

Another drawback is the large area required for the implementation of the well-known solution, which is associated with the presence of an entry-exit, which, in turn, requires areas for moving and maneuvering vehicles between parking spaces in the parking lot. The need for maneuvering in the parking area creates inconvenience and reduces the security of using the known solution when searching for a parking place. In addition, this drawback makes it unacceptable to use a well-known solution in a limited city space.

These disadvantages limit the scope of the known solutions.

The technical result of the invention is to simplify the design, increase the reliability of localization and identification of vehicles within a parking space in conditions of poor visibility, precipitation and surface pollution, and, as a result, the ability to control payment for parking, increase the convenience and reliability of operation, as well as improve safety at parking.

The invention is illustrated using the drawings, where in FIG. 1 schematically shows an example of a parking complex at the edge of the carriageway, FIG. 2 is a general view of an induction parking column, FIG. 3 is a block diagram of a parking complex.

The parking complex contains many parking spaces with markings for parking vehicles, and each parking space is equipped with an antenna - the magnetic frame of the reader - and means of information, which are used as light or sound detectors used to inform the driver about the status of the respective parking space. The magnetic frame of the reader and the means of information are integrated in the induction parking column located in the immediate vicinity of the parking space, while the light detector is placed in the driver's field of view at a height of more than 0.5 meters to prevent it from being obscured by elements of the engine compartment of the car. The size of the light detector and the brightness are selected based on ensuring its visibility at any time of the day, in any weather conditions and at any time of the year.

Information tools include three main nodes: a light and / or sound detector, a controller unit on an FPGA or microprocessor with detector drivers with a data interface controller, which are elements of a computing tool, and a power source. In this case, the power source may be part of the controller.

The detector controller is multi-channel for servicing several parking spaces and is connected to the inputs of the respective detectors.

On the territory of the parking complex there is a parking unit, made by a separate cabinet in a vandal proof housing, in which a reader, multiplexer, detector controller and power supply controller are installed.

The reader and antennas of the parking space operate in the range from 30 kHz to 30 MHz and are made with the possibility of reading data fixed on the vehicle’s license plate at a height of 30 to 120 cm of a radio tag - transponder, at a distance of 30 to 100 cm.

The induction parking column is made of dielectric material, resilient or equipped with a spring mechanism. The design of the induction parking column provides for placement inside the control and power cables, as well as their combination with connectors for docking with the cable network of the parking zone.

The antennas of the parking spaces are connected through the multiplexer to the inputs of the reader, the output of which is connected to the corresponding inputs of the calculation tools that provide calculation and verification of payment, and the output of the calculation tools is connected to the corresponding inputs of the detectors to provide control of the information tools. Calculation tools are also connected to a payment system that provides the possibility of paying for parking.

In the event that the parking complex is combined with other parking complexes in one system, the means for calculating the nodes of the parking complexes are connected to the control computer.

Parking complex operates as follows.

To enable the use of the parking complex, the vehicle is equipped with a radio tag (transponder) integrated in the registration number plate containing the identification data of the vehicle and / or driver.

To inform the driver about the state of the parking, each parking space contains means of light and / or sound informing, providing information to the driver about the following conditions of an individual parking space:

- parking does not work;

- parking is working, the place is free or the car is not detected;

- a car with a tag is found in the zone, its identification and verification is carried out;

- the car is parked, identified and verified correctly, correctly parked;

- the car is parked, identified or verified incorrectly, incorrectly parked.

The light detector is mounted on top of the induction parking column and is clearly visible to the driver.

The driver selects a parking space, the corresponding detector of which informs him that the parking is working and the parking space is free, goes to the free parking space of the parking complex and parks, as indicated by the light detector.

To ensure optimal interaction between the magnetic frame and the RFID tag of the vehicle, the magnetic frame is integrated into the induction parking column installed in the immediate vicinity of the vehicle parking place, and the induction parking column itself is made of dielectric material.

Placement of the mark on the front bumper of the vehicle, in the place of the vehicle’s GRZ or nearby, at a height of 30 to 120 cm, provided that the vehicle is parked in front of the antenna of the induction parking column, provides a communication range of the column and mark of up to 1 meter.

The identification zone of the vehicle mark across is from 30 to 100 cm, which provides the necessary control of the correct parking of the vehicle within an individual parking space.

The fact of parking and occupancy of a parking space is determined using a proximity sensor, which is used as an antenna of an induction parking column, which at the same time performs the function of a contactless induction sensor-detector, the coverage area of which coincides with the identification area of the TS mark.

To reduce the risks of damage to the design of the individual parking equipment located in the induction parking column (detector, antenna, cable connections), as well as the vehicle structure, in case of collision during improper parking, this column is made of a dielectric that allows elastic deformation, or equipped with a spring mechanism in the place of attachment of the base. The specified column also has a corresponding retroreflective coating for its visual detection by the driver.

The equipment of individual parking spaces, the number of which is determined by the address space of the information exchange standard (typical value from 2 to 256), is reduced to one parking unit, made in a vandal-proof housing, and includes a reader, multiplexer, detector controller, and power supply controller.

The parking lot is also equipped, if necessary, with a climate control system, heaters, a functional control system, a network hub, a control computer, a wireless communication system, and an uninterrupted power supply.

The calculation tools perform the functions of a local server performing the functions of a parking complex management system, access control to parking spaces, data exchange with the upper level: payment systems, servers of the upper hierarchy.

The control computer is located at the operator’s workplace and, together with the monitor, performs the functions of the operator’s automated workplace. At the same time, the control computer can process information from several parking nodes (parking complexes).

In the case of establishing the fact of parking a vehicle without payment, the computing facilities of the parking complex generate a signal to the operator about illegal parking with the identification data of the parking column, near which an unknown vehicle is parked.

The parking complex using induction parking columns does not require control at the entrance and exit to the parking area, since all the necessary parking control is carried out directly at the parking space. At the same time, the use of a multiplexer that provides the operation of multiple antennas with one controller makes the system structurally simple and cheap. Induction parking columns are loaded with a small amount of electronic equipment, the main of which are antennas - magnetic frames, which makes the manufacture of induction parking columns simple and technologically advanced.

The use of radio-frequency identification of vehicles provides high reliability of identification in difficult weather conditions of precipitation and ice accumulation and, as a result, provides the ability to control the payment of parking space in these adverse weather conditions. The parking complex is easier to use, as it requires obvious logical actions from the driver related to driving to the chosen parking space. In addition, due to the absence of the need for the construction of masts and supports of barriers, the use of a parking complex using induction parking columns provides greater traffic safety. The safety and convenience are also facilitated by the absence of the need for maneuvering along a narrow passage from the barrier to the parking space, due to the absence of the barrier.

When placing induction parking poles in parking pockets with minimal environmental impact, for example, under a canopy, induction parking poles are equipped with a miniature IT camera, which is used for additional identification of the vehicle by license plate, which increases the reliability of identification.

The parking complex can be implemented on standard elements, radio components, using wired and wireless communication lines. The reader can be made on the basis of standard, commercially available units, for example, HF Long Range reader ID ISC.LR (M) 2500 manufactured by FEIG Electronic.

Thus, the parking complex is structurally simpler, has a higher reliability of localization and identification of vehicles within the parking space in conditions of poor visibility, precipitation and surface pollution, and, as a result, provides the ability to control payment for parking, is more convenient and reliable to use and also provides great parking security.
