Description

Technical Field

[0001] This utility model relates to the technical field of parking fee collection systems, and in particular to a ground geomagnetic field. Background Technology

[0002] In modern society, with the continuous growth of car ownership, the problem of parking difficulties in cities has become increasingly prominent, especially in high-density urban areas where the supply of parking spaces generally falls short of demand. To alleviate this problem, many cities have begun to set up temporary parking spaces on both sides of roads to make full use of urban space. However, the management of these roadside parking spaces faces a series of challenges, especially in the charging process.

[0003] Existing roadside parking fee collection methods mainly include manual inspection and collection, smart parking pile collection, and parking meter time-based card payment.

[0004] Currently, the main intelligent roadside parking payment system relies on manual inspection and payment. Although this method uses ground vehicle detectors to sense parked vehicles, it still requires manual operation of a handheld PDA device to collect payment on-site. This method is not only inefficient, but also increases the time spent by parking owners on scanning QR codes for payment (and if the owner forgets to bring their phone, they cannot pay and leave in time) and the workload of management personnel. Furthermore, it cannot provide continuous 24 / 7 service, limiting its effectiveness in practical applications.

[0005] In recent years, the development of smart parking pile payment technology has brought new solutions to roadside parking management. This technology, through the integration of video recognition, can automatically identify vehicle information and achieve 24 / 7 automated parking management. However, smart parking pile payment systems also have some limitations. First, smart pile devices are typically large in size and occupy a significant area, making them difficult to deploy in space-constrained road sections. Second, the installation of smart piles requires complex wiring, which not only increases initial deployment time but also raises costs. Furthermore, the maintenance and upgrading of smart piles are relatively difficult, and a malfunction could disrupt the entire parking management process.

[0006] While parking meter-based charging systems reduce labor costs to some extent, their operation relies entirely on drivers' self-discipline, leading to frequent instances of fare evasion and making fee collection and supervision difficult, thus affecting the efficiency and fairness of parking management.

[0007] To effectively address the parking problem and improve the utilization efficiency of parking spaces, intelligent parking systems have emerged. Among these systems, ground magnetic sensors play a crucial role as parking space detection equipment. However, traditional ground magnetic sensors are typically designed for a single function, such as detecting the presence of a vehicle. Furthermore, their energy supply methods are relatively limited, relying mainly on built-in batteries or external power sources. This not only increases maintenance costs but is also detrimental to environmental protection. Utility Model Content

[0046] It is understood that in some embodiments, the first communication module 8 is a 5.8GHz transceiver module and the second communication module 17 is an NB-IoT module.

[0047] Specifically, the solar power conversion management circuit module 21 is responsible for charging via solar energy and managing the charging and discharging process of battery 14 to prevent overcharging and over-discharging.

The geomagnetic sensor circuit module 20 communicates with the main control chip module 18 via the I2C protocol.

The main control MCU controls the BK5822 through SPI to realize the RSU function.

[0048] This embodiment describes a ground-based geomagnetic system. The multi-layer frame 13 includes multiple first columns 23 and a first base plate 24. The first columns 23 are all located at the bottom edge of the first base plate 24, and their bottoms are connected to the housing 1. The first columns 23 are located on the outer periphery of the battery 14. Specifically, the design of the multi-layer frame 13 not only optimizes the internal space of the equipment but also ensures the stable installation of the battery 14 and other components, improving the structural strength and reliability of the equipment.

[0049] In this embodiment of the ground magnetic field, a plurality of positioning blocks 25 are protruding on the inner wall of the housing 1. The edge of the battery 14 abuts against the positioning blocks 25, and the bottom of the first column 23 is connected to the top of the positioning blocks 25. Specifically, three positioning blocks 25 are provided, which abut against the three outer walls of the battery 14 respectively, improving the fixing effect of the battery 14, preventing the battery 14 from loosening due to vibration during use, and extending the service life of the device.

[0050] This embodiment describes a ground-based geomagnetic system. The multi-layer frame 13 includes multiple second pillars 26 and second base plates 27. The second pillars 26 are disposed on top of the first base plate 24, and their tops are connected to the second base plates 27.

The first circuit board 28 is disposed on the first base plate 24, and the second circuit board 29 is disposed on the second base plate 27.

It can be understood that each circuit module can be distributed on the first circuit board 28 and the second circuit board 29 according to the actual situation.

A third through-hole 31 is formed on the second substrate 27, penetrating both the upper and lower ends of the second substrate 27. Specifically, through the first through-hole 12, the second through-hole 30, and the third through-hole 31, wiring can be routed between the various components to achieve electrical connection.

[0052] In this embodiment of a ground-based geomagnetic system, a first base plate 24 is provided with a plurality of first positioning posts 32, and a first circuit board 28 is fixed to the top of the first positioning posts 32 by fasteners. A second base plate 27 is provided with a plurality of second positioning posts 33, and a second circuit board 29 is fixed to the top of the second positioning posts 33 by fasteners. Specifically, by setting positioning posts and fixing the circuit board with fasteners, the stable installation of the circuit board is ensured, preventing poor contact caused by vibration. At the same time, the first circuit board 28 and the second circuit board 29 are saved, allowing them to be suspended, thereby improving the stability and service life of the equipment.

[0053] The ground magnetometer described in this embodiment has multiple grooves 34 arranged around the outer periphery of the housing 1, with the spacing between any two adjacent grooves 34 being the same. Specifically, the multiple evenly distributed grooves 34 on the outer periphery of the housing 1 can increase the friction of the device, prevent the device from sliding during installation and use, and improve the installation stability and safety of the device.
