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, “difficult parking” in traffic has increasingly become a “bottleneck” restricting urban economic and social development. In some developed cities It’s hard to find a parking space in the central city of China. Faced with the contradiction between the increasing number of vehicles and insufficient road capacity and parking resources, relevant parties are also actively solving road traffic management problems, how to improve the current status of traffic and solve parking difficulties The city government and relevant leaders attach great importance to the problem of, and the people are concerned about it. In view of this, it is necessary to plan, optimize and manage the city’s roads, traffic, and parking in a unified way. Fully tap the urban parking resources, especially the scientific and reasonable expansion of roadside parking resources, and realize the efficient use of parking resources through the economic lever of reasonable charges for roadside parking, and provide efficient, convenient and orderly traffic and parking for the city. Services to improve the city’s traffic congestion and parking difficulties.
Program overview
The parking lot management system is a set of technology that applies 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 the management of vehicle flow guidance, parking status information release, parking fee collection, etc., through the intersection release screen, WEB, mobile phone client, etc. to release dynamic information to the vehicle management department and vehicle owners, which is convenient for management personnel to dispatch. Reduce the labor intensity of management personnel, use toll management software to effectively monitor parking fees, prevent private parking and evasion and arrears, and effectively prevent toll loopholes; at the same time, the system can achieve real-time data collection and docking with traffic police data. Relevant traffic, violation reminders, convenient services, and networked with public security traffic police to report to the police.
working principle
This program uses the principle of geomagnetism to detect vehicles. In the absence of motor vehicles, the earth’s magnetic field is in a relatively stable state. When a motor vehicle stops above the earth’s magnetism, it will cause changes in the earth’s magnetic field. The wireless geomagnetic parking space detector analyzes the changes in the earth’s magnetic field through a built-in algorithm, and finally determines whether the parking space has parked a motor vehicle. The wireless geomagnetic parking space detector adopts a fully buried method, and each parking space is installed with 1~2 (depending on the specific parking space). It is powered by its own battery. 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. The system records the time of entering the vehicle and transmits the information to the toll collector’s handheld terminal (PDA, POSE) , Mobile phones, etc.), and send text messages related to parking service charging standards and other related information to the mobile phone reserved by the car owner. The toll collector can input the vehicle license plate number through the handheld terminal to perform 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 the vehicle is found to have unpaid records, it will prompt whether the vehicle has arrears records or not; if it is necessary to pay, the toll collector needs to do another entry operation after recovering the fees; if not, or If there is no record of arrears, then print the admission notice (with barcode) and deliver it to the owner. The owner can leave, and the toll collector will continue the following operations: take a photo of the vehicle in the near and far view, then upload the admission data to the server and enter the venue End of process
If the system is enabled with the function of networking with the traffic police system, after entering the parking lot, the violation information query, notification, processing, and tracking will be carried out.
Vehicle departure management
The toll collector selects the parking number of the vehicle to be exited on the entry and exit interface of the handheld terminal, enters the exit interface, and displays the parking space and parking fee of the vehicle, and the public security traffic police system is linked to the police and the query result is displayed. After confirming with the owner, The car owner pays, the toll collector clicks “leave”, prints the “vehicle toll sheet” and delivers it to the owner; the vehicle “leaves”, the wireless geomagnetic parking detector senses that there is no vehicle, records the time of departure of the vehicle, and compares it with the time of entry, As the standard for the operating department to judge the fees received, the comparison between the final statistical cost and the actual income cost can be used as an assessment basis for the toll collectors. If the amount differs greatly, the toll collectors can be punished accordingly.
The exit 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 geomagnetic sensor can distinguish the change of 1/6000 of the earth’s magnetic field. The influence on the geomagnetism when passing will reach a fraction of the intensity of the geomagnetism, so the use of geomagnetic sensors to detect vehicles has extremely high sensitivity.
☆ Convenient installation and maintenance, no need for excavation and construction, and little damage to the road surface. If the detector is damaged, you only need to replace it as a whole without checking the circuit.
☆ 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, so 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 ISM microwave frequency band that is open worldwide does not require application and payment.
☆ Ultra-low power consumption: safer and healthier for the human body.
☆ Long service life, up to more than 5 years.
☆ Low investment cost, and once the system is applied, it can greatly reduce parking lot management personnel and reduce parking lot operating costs.
