CZ33897U1 - Parking occupancy monitoring system for vehicles up to 3.5 t - Google Patents

Description

Field of technology

The solution concerns the monitoring of car park occupancy for vehicles over 3.5 t.

Prior art

Technologies based on magnetic, infrared, ultrasonic and radar sensors or their combinations are currently used to monitor the occupancy of car parks for vehicles over 3.51, the sensors are located in the roadway at the marked parking place.

Furthermore, camera systems with image analysis monitoring the car park are used.

These systems make it possible to determine with high accuracy the occupancy of a parking space, its location and the occupancy time of a specific parking space. Any error in determining the occupancy of a parking space is not accumulated, but is corrected during the subsequent cycle of evaluating the occupancy of parking spaces.

There are also known systems that detect and count cars at the entrance to a parking lot. To detect an oncoming car, standard technologies are used - inductive loops, cameras, magnetic, infrared, ultrasonic and radar sensors or their combinations located either in the roadway or in the area at the entrance to the parking lot. These systems (incremental) have the disadvantage that in the event of an error in the detection of an incoming vehicle, these errors accumulate and the correction to the correct state of parking space occupancy must be performed once in a while manually - by physical control and entering the correction into the parking system.

The disadvantage of these systems is that they require costly installation and subsequent maintenance of sensors and data transmission equipment.

The essence of the technical solution

These shortcomings are remedied by a system for monitoring the occupancy of car parks for vehicles over 3.5 t, which consists of a satellite navigation system, a vehicle on-board unit, a variable traffic signage device and / or an information and / or data processing device, eg a computer, tablet, smart telephone, satellite toll system computing unit comprising software, parking system computing unit comprising software, parking owner / operator computing unit comprising software, the satellite navigation system being connected to the vehicle on-board unit, the vehicle on-board unit via a mobile data network, eg 2G, 3G, 4G, 5G connected in both directions with the computer unit of the satellite toll system, the computer unit of the satellite toll system is bidirectionally connected to the computer unit of the parking system, computer unit of the parking system it is bidirectionally connected to the computing unit operator / owner car, a computer unit of the owner / operator of parking is bidirectionally connected to the computing unit of variable traffic signs, and / or data processing device and / or an information device.

The mentioned solution uses a satellite toll system to monitor the occupancy of car parks for vehicles over 3.5 t, which is primarily used to collect tolls for the use of toll roads.

- 1 CZ 33897 U1

The amount of the toll is determined by means of an electronic toll system, which makes it possible to determine, in particular, the distance traveled by vehicles on tolled roads, the registration of toll data, the collection of tolls and the control of toll payment.

Every vehicle over 3.5 t, which is subject to the obligation to pay tolls, is equipped with an on-board unit of the vehicle, which is an electronic device that is non-transferable and its use is tied to a specific vehicle registered in the electronic toll system. The electronic device enables unambiguous identification and position of the vehicle by the electronic toll system. While driving, it records vehicle position information using a satellite navigation system.

Within the operation of the electronic toll system, electronic devices are used that integrate several technologies.

Satellite technology, satellite navigation system, such as GPS, GNSS, Gallileo, determines the location, ensures the collection of data on the use of toll roads. The electronic device records the position of the vehicle, receives signals from the satellite navigation system.

The satellite navigation system is complemented by technologies for communication within mobile networks and toll collection control, such as GSM (Global System for Mobile Communications) / GPRS (General Packet Radio Service), used for data transmission between the vehicle unit and other information systems within the system. electronic tolls, in particular with the calculation units of the toll system.

Another technology is short-range communication technology, such as microwave DSRC (Dedicated short-range communications), which is used to control toll payers as part of the toll collection control process.

The satellite navigation system recognizes that the vehicle is traveling on a toll road and, on that basis, creates an appropriate record, the so-called toll event. This data is sent by the mobile network to the central information system, in which it is used to determine the amount of tolls.

The satellite toll system obtains up-to-date data on the position of the vehicle, in addition obtains information on • the vehicle registration number and the country in which the vehicle is registered • vehicle category according to applicable legislation • total vehicle weight, number of axles and vehicle emission class • name or trade name, where applicable, the name of the vehicle operator;

• name or business name, or name and surname of the vehicle owner, if different from the vehicle operator • e-mail address of the vehicle operator

Information on the position of the vehicle is used to monitor the occupancy of the car park, other information is used for statistics or, in the case of paid car parks, to automatically select payment for parking.

Each car park is defined by coordinates as a space with defined boundaries. If the vehicle is located in a defined area, it is the occupation of a parking space.

Leaving this area by the vehicle indicates the free parking space. Based on the information of the position of the parked vehicle, it is possible to display with the accuracy of the satellite navigation system

-2 CZ 33897 U1 position of the parked vehicle on the parking area. Alternatively, microwave (DSRC) technology can be used to increase the reliability of the entire parking system, and especially when collecting the parking fee.

The computing unit of the satellite toll system comprising the software receives the vehicle position data from the on-board unit of the vehicle based on a wireless connection, e.g. a mobile data network, e.g. 2G, 3G, 4G, 5G. From the computer unit of the satellite toll system, this data is transmitted to the computer unit of the parking system including the software.

Furthermore, information on the occupancy of the car park is transmitted to the computer unit of the owner / operator of the car park and from there to the information devices or devices of variable traffic signs located before the entrance to the car park. In a preferred embodiment, this information is transmitted to systems for informing drivers about the occupancy of parking lots, for example applications for smartphones and tablets.

Monitoring the occupancy of parking spaces for vehicles over 3.5 t using data from the satellite toll system brings great savings compared to currently used technologies, is very quickly feasible and is reliable and accurate due to the reliability and accuracy of the satellite toll system. The advantages of this solution include saving the need to install other technologies necessary for local detection of parked vehicles, determining the occupancy of the parking lot, and associated costs, such as building permits, etc., all necessary information for monitoring parking occupancy can be obtained from a satellite toll system. It saves drivers time when looking for a free parking space.
