　　IoT RFID intelligent parking management solution

　　Traffic-related problems such as traffic congestion, parking difficulties, random parking, accident disputes, vehicle safety, and environmental pollution are becoming more and more serious. In particular, traffic "parking difficulties" has increasingly become a "bottleneck" restricting urban economic and social development. In some developed cities It is difficult to find a parking space in the central urban area of the city. Facing the contradiction between the increasing number of motor vehicles and the lack of road transport capacity and parking resources, relevant parties have also actively solved the problem of road traffic management, how to improve the current situation of traffic and solve the problem of parking difficulties. The problem of urbanization has been highly valued by the municipal government and relevant leaders and has been greatly concerned by the public. In view of this, it is necessary to carry out unified planning, optimization and management of urban roads, traffic and parking. Fully tap urban parking resources, especially expand roadside parking resources scientifically and rationally, and realize efficient use of parking resources through the economic lever of reasonable charges for roadside parking, providing efficient, convenient and orderly traffic and parking in the city services, thereby improving the city's traffic congestion and parking difficulties.

　　Program overview

　　The parking lot management system is a set of parking lot vehicles built by using computer technology, RFID technology, wireless transmission technology, image digital processing technology, automatic control and other technologies through computers, network equipment, vehicle perception transmission equipment, customer terminal equipment, etc. A comprehensive management platform for management of traffic flow guidance, parking space status information release, and collection of parking fees, etc., through the intersection release screen, WEB, mobile client, etc. to release dynamic information to the vehicle management department and vehicle owners, which is convenient for management personnel to schedule. Reduce the labor intensity of management personnel, use toll management software to effectively supervise parking fees, eliminate private parking evasion and arrears, and effectively prevent charging loopholes; at the same time, the system can achieve real-time data collection and connection with traffic police data. Relevant traffic, illegal reminders and convenience services, and network alarm with the public security traffic police.

　　working principle

　　The scheme uses the geomagnetic principle to detect vehicles. In the absence of motor vehicles, the Earth's magnetic field is relatively stable. Changes in the Earth's magnetic field are caused when a motor vehicle is parked above the Earth's magnetism. The wireless geomagnetic parking space detector analyzes the change of the earth's magnetic field through a built-in algorithm, and finally determines whether a motor vehicle is parked in the parking space. The wireless geomagnetic parking space detector adopts the fully buried method, and each parking space is installed with 1~2 pieces (depending on the specific parking space situation), powered by its own battery, and the professional low-power technology guarantees the geomagnetic service life of more than 5 years.

　　Vehicle admission management

　　When the vehicle enters the parking space, the wireless geomagnetic parking space detector detects the existence of the vehicle, and transmits the information to the management background through the roadside signal receiver. , mobile phone, etc.), and at the same time, send a short message about the parking fees and other related information to the mobile phone reserved by the car owner. Toll collectors can input the vehicle license plate number through the handheld terminal and do related business operations. If the site has a camera, it can be linked with the detector to capture vehicle photos.

　　Through data and image comparison, if it is found that the vehicle has a non-recovery record, it will prompt whether the vehicle has a record of arrears and whether to make up; If there is no arrears record, then print the admission notice (which can contain barcode) and deliver it to the owner, the owner can leave, and the toll collector continues the following operations: take close-up and long-range photos of the vehicle, and then upload the admission data to the server for admission. Process ends

　　If the system has enabled the function of networking with the traffic police system, after entering the parking lot, it will query, notify, process and track violations of laws and regulations.

　　Vehicle departure management

　　The toll collector selects the parking space number of the vehicle to be departed on the entry and exit interface of the handheld terminal, enters the exit interface, displays the parking space and parking fee of the vehicle, links with the public security traffic police system to alarm and displays the query result, and confirms it with the owner. The car owner pays, the toll collector clicks "Leave", prints the "Vehicle Charge Note" and delivers it to the car owner; when the vehicle "leaves", the wireless geomagnetic parking space detector senses no vehicle, records the vehicle's exit time, and compares it with the entry time. As the standard for the operation department to judge and accept fees, the final statistical fee is compared with the actual income and expenses, which can be used as the basis for the assessment of the charging personnel. If the difference is large, the charging personnel can be punished accordingly.

　　The departure process is over.

　　System Features

　　☆ High precision: The earth's magnetic field is basically constant within a few kilometers, but large ferromagnetic objects will cause huge disturbances to the earth's magnetic field. The impact on the geomagnetism will reach a fraction of the geomagnetic intensity when passing through, so the use of geomagnetic sensors to detect vehicles has extremely high sensitivity.

　　☆ Easy installation and maintenance, no need for excavation and little damage to the road surface. If the detector is damaged, it only needs to be replaced as a whole, no need to check the wiring.

　　☆ The geomagnetic sensor uses the change of the earth's magnetic field when ferromagnetic objects pass through to detect, so it is not affected by the climate.

　　☆ The two-way high-speed data exchange can be realized between the detector and the receiver, and there is no need to worry about the simultaneous data exchange between each detector and the receiver.

　　☆ High reliability, working temperature -40℃~85℃, waterproof and shockproof.

　　☆ High anti-interference: There are no special requirements for various interference sources on site, and the installation is convenient and simple.

　　☆ The global open ISM microwave frequency band, no need to apply and pay.

　　☆ Ultra-low power consumption: safer and healthier for the human body.

　　☆ Long service life, up to more than 5 years.

　　☆ The investment cost is low, and once the system is applied, it can greatly reduce the parking lot management personnel and reduce the parking lot operating cost.
