DETAILED DESCRIPTION OF THE INVENTION

The following detailed description of the invention sets forth numerous implementation details designed to provide a clear understanding of the present invention. However, it will be apparent to one skilled in the art how the present invention can be used with or without these implementation details. In other cases, well-known methods, procedures and components have not been described in detail so as not to unduly obscure the features of the present invention.

Numerous possible modifications, alterations, variations and substitutions, while retaining the spirit and form of the present invention, will be apparent to those skilled in the art.

The proposed technical solution is aimed at solving the problem of constructing an information network for transmitting and processing data on the status (free/occupied) of a parking space for storing vehicles in real time.

The proposed software and hardware complex for building an information network for transmitting and processing data on the state of a parking space for storing vehicles in real time, contains interconnected: at least one wireless vehicle detection sensor, implemented in the form of a geomagnetic surface-mounted parking sensor with radar detection; a wireless data collector implemented as a gateway to communicate between all wireless parking sensors and the server; a cellular data transmitter implemented to transmit data to a server paired with a wireless data collector.

The wireless vehicle detection sensor (OKSI PS-x) is designed to obtain information about the availability of a parking space without use of cables. Using magnetism and lidar detection technology, low-power long-range wireless transceiver protocol, and sophisticated detection algorithm, OKSI PS-x achieves extremely high detection speed and long communication range, providing an easy-to-install and cost-effective solution for measuring parking occupancy data spaces both indoors and outdoors and outdoor parking management systems.

OKSI PS-x is a surface-mounted geomagnetic parking sensor with radar detection based on the standard LoRaWAN protocol to determine the status (occupied or empty) of a parking space. It consists of a vandal-proof protected housing, a mounting ring, a data transmission module (printed circuit board/chip with lidar function), and a power source - battery. The operating principle is based on the operation of a magnetic field or optical detection (lidar) activating the data transmission module.

1. Detection due to the formation of a magnetic field, when a car is parked in a parking space or leaves it, the sensor records the change in the magnetic field and an encrypted data packet about the state of the parking space is transmitted to the gateway (collector), while the gateway in turn transmits the information to the computing server , after which the network server decodes the data packet and adjusts the interface with the intelligent parking platform to manage parking lots in real time.

2. Optical detection of the vehicle by the sensor, based on the application of lidar function. Infrared radiation detects a metal object in a given range, determining the distance to it and transmits data to the data collector (gateway) about its status (free/busy).

Magnetic and optical data detection are two independent functions of the parking sensor. Their operation is determined based on precise settings. The functions work both in real time (online) and in pulsating mode with a specified time interval.

A PS sensor installed in each parking space detects the presence of a vehicle. Through a wireless sensor network between the sensor(s) and the data collector (OKSI DCR-xxx) installed in the parking lot, real-time occupancy information will be detected and transmitted to the system database for further maintenance of the parking management system. The OKSI DCR-xxx wireless data collector acts as a gateway between all wireless parking sensors and the data server. The OKSI DCR-xxx provides ultra-long-range wireless performance, enabling sensor connectivity over a large area. Due to the use of LBLRTM technology on the DCR-xxx, only one data collector can be installed per application site, which provides the benefits of reducing system costs and simplifying the system for improved stability and efficiency.

OKSI provides 4 different DCR-xxx radio frequency models to meet the wireless radio requirements of different countries and regions. The information is below:

Model DCR-433 DCR-915 DCR-470 DCR-868

Frequency 433 MHz 915 MHz 470 MHz 868 MHz

The OKSI DCR-xxx Wireless Data Collector provides ultra-long-range wireless performance, providing widespread connectivity to wireless sensors installed over a large area, such as an open parking lot or street parking lot. Data on the occupancy of parking spaces received from each sensor of the entire network is transmitted to the data server of the application system using DCR-xxx via the Ethernet or RS232/485 communication port in the form of an encrypted code in bit-ax.

OKSI DCR-xxx is an aluminum case with exposed ports. Inside the case there is a power supply and a printed circuit board with RS-232/485 (configurable), Ethernet and USB (configurable) ports for data transfer between the wireless parking space occupancy detection sensor and the server.

Reception of data from parking sensors is carried out using the LORA protocol. Data packets use the same frame regardless of the port from which they are transmitted. The USB port is used for debugging. RS-232/485 port (configurable) and Ethernet port, work as a TCP/IP client. Data transfer rate 115200 bps.

The international LORA WAN protocol is used for integration and data transfer. LoRa technology is designed for machine-to-machine (M2M) communication and is a combination of a special LoRa modulation method and open LoRaWAN communication protocol. This IoT connectivity technology is designed in such a way that it can serve up to 1 million devices on a single network, giving them up to 7 years of autonomy on a single battery.

OKSI DCR-xxx has a front panel and a rear panel. The front panel contains operating status indicators, a USB port, boot and preset buttons, and a user input switch. The rear panel contains the DC power connector and terminal, Ethernet and RS-232/485 data ports, and a TNC antenna connector.

The USR-G781 Cellular Data Transmitter is a 3G and 4G DTU that applies to LTE and GPRS. This is a separate device for data transmission using mobile systems, working in tandem with a collector (gateway). The RS232 or RS485 serial port can transmit data to the Internet server using LTE technology. The G781 has two Ethernet ports for connecting network accessories.

The cellular data transmitter works in conjunction with the gateway (data collector) and transmits the data received by the gateway from parking sensors.

By connecting the collector's RS-232 port to a GPRS/3G DTU, which is typically used to convert data from RS-232 format to TCP/IP format, the collector can transmit data via a GPRS or 3-4G wireless network to a server connected to the Internet with a public IP -address and port number.

The proposed technical solution can be implemented using a server infrastructure capable of performing the necessary data processing. The server infrastructure may consist of network equipment, server (computing) equipment, disk and other storage.

A packet of data from parking sensors is sent to the server using a collector. The server receives, processes, analyzes and transmits data to other partners in a structured form. Administrators managing parking space connect and receive data through APIs that are deployed on the server.

Data transmitted to the server from the sensor in real time:

- Parking space status (occupied/free);

- Sensor availability (online/offline);

- Battery charge level (depending on the sensor configuration).

In FIG. 1 describes a data packet sent from the server in the form of a digital code signal whenever the sensor status changes in real time. Data packet decryption:

101 — frame head;

102 - data packet type (in this technical solution there are two types of data packet, 00 - heartbeat data packet, 01 - detection data packet);

103 — serial number of the data package;

104 — data packet length;

105 is the detection status of the sensor, to avoid data packet loss due to wireless interference, the heartbeat data packet also includes the detection status following the detection packet, 02 means the free state detected by the magnetic sensor; 00 means free status detected by lidar sensor.

106 - Data Collector ID (opposite direction, ID should be read as 68638310);

107 - sensor identifier (opposite direction, identifier should be read as 68638950);

108 — sensor voltage value; 109 — sensor signal strength (temp);

110 — sensor firmware version;

111 — control value of the data packet.

Thus, the server part is an integral part of this complex, which receives, stores, processes, analyzes and transmits data to managing administrators in a structured form.

The software and hardware complex allows:

- the user, in real time, sees a map indicating free and occupied parking spaces;

- the network administrator receives data on the number of occupied and free parking spaces in real time.

Additional positive technical effects of this hardware and software complex:

- reducing the user’s time searching for a free parking space;

- the possibility of contactless payment for a parking space;

- integration of a transponder for automatic payment for a parking space;

- the ability for network administrators to receive data on peak loads for each parking space;

- the ability for network administrators to receive data about vehicles and drivers occupying a parking space;

- reduction of traffic around paid parking lots due to efficient data processing and display of the status (free/occupied) of the parking space for storing vehicles.

- the possibility of introducing regulated tariffs during peak parking loads, due to accurate analytics of the software and hardware complex.

The OKSI DCR-xxx Wireless Data Collector provides ultra-long-range wireless performance, providing widespread connectivity to wireless sensors installed over a large area, such as an open parking lot or street parking lot. Information about the occupancy of parking spaces is transmitted to the data server of the application system using OKSI DCR-xxx via an Ethernet or RS232/485 communication port. The data collector listens to the airwaves in a given frequency range. When it hears a request from any of the devices, it responds to it at the request frequency. Its task is to transmit a small sender message as quickly and reliably as possible to the server. Depending on the radio conditions, the optimal set of communication parameters is selected.

The packets are received by the data collector, but are processed by the next link in the chain - the network server. It is on the application server that the readings from the sensors are deciphered; they are distributed in an understandable form either to billing, or to the consumer interface, or to another specified location.

The “City Parking” network is configured by connecting the configured collector to a network server via Ethernet or mobile networks (Fig. 3).

The user drives his vehicle into the parking lot and takes a parking space. A wireless vehicle detection sensor detects a vehicle and sends information in the form of a digital signal (code) to the data collector, after which the data collector receives the information and forwards it to the data server. On the server, the information is analyzed and processed and, depending on the signal (code), the sensor status (free/busy) is identified. After that, the status of the parking space changes in the application database, and the user interface displays reliable information about the occupancy of the parking space and the parking lot in general.

The proposed system has software (a set of software tools) for connecting to the database (server) of the “City Parking City N” application. The “city parking N” application receives data from the server in the form of a digital code signal every time the sensor status changes in real time. Thus, the user, through his computing device, can obtain information regarding available parking spaces, as well as use the generated route to the optimal parking space.

Thus, the present technical solution, due to its implementation and use of all technical elements of the system, selects optimal parking lots for the user, in which there are free parking spaces, and displays information for the user indicating the parking number or the name of the parking lot, as well as the number of the free parking space.

In these application materials, a preferred disclosure of the implementation of the claimed technical solution was presented, which should not be used as limiting other, private embodiments of its implementation, which do not go beyond the scope of the requested legal protection and are obvious to specialists in the relevant field of technology.
