Roadside parking, as a crucial component of the urban parking system, faces prominent issues such as parking difficulties, chaotic pricing, and low management efficiency. Traditional manual payment methods suffer from financial loopholes, high labor costs, and rampant payment evasion. While simple geomagnetic detection can sense parking space status, it lacks interactive payment capabilities. The "parking meter + geomagnetic sensor" solution has emerged to address these challenges. Through complementary technologies, it constructs a smart parking meter system covering the entire chain of "sensing, billing, payment, and management," becoming one of the mainstream technological approaches for urban roadside parking management.
Technical Architecture and Composition
System Architecture
This solution adopts a three-layer architecture design:
Data Acquisition Layer: Geomagnetic Sensor + Smart Parking Meter. The geomagnetic sensor is responsible for detecting parking space status, and the parking meter is responsible for timekeeping, billing, and payment interaction.
Information Transmission Layer: Geomagnetic Manager/NB-IoT Base Station. Real-time data upload is achieved through 4G/5G/NB-IoT networks.
Management Application Layer: Smart Parking Cloud Platform + Mobile APP. Data analysis, fee settlement, parking space guidance, and operation monitoring.
1. Geomagnetic Sensor (Geomagnetic Detector)
Working Principle: Utilizing the principle of the uniformity of the Earth's magnetic field, when a ferrous vehicle enters/leaves, the magnetic field is disturbed. The sensor determines the parking space occupancy status by detecting the change in the magnetic field.
Technical Features:
- Detection accuracy can reach over 99%.
- Ultra-low power consumption design, battery life up to 5 years.
- Buried installation, does not occupy road space, convenient construction.
- Supports NB-IoT wireless communication, no wiring required.
2. Smart Parking Meter
- Multimodal Smart Terminal: Supports cash, bank card, and QR code payment (optional)
- Scenario: Self-service payment mode (geomagnetic sensor + fixed parking meter)
- Applicable to: Urban areas with mature parking habits and low rates of parking evasion
Process:
1. Entering a parking space: The geomagnetic sensor detects the vehicle entering, and the system displays the parking space status as occupied.
2. Parking: The driver purchases parking time.
3. Leaving a parking space: The geomagnetic sensor detects the vehicle leaving, and the system displays the parking space status as vacant.
If parking time exceeds the limit, the system triggers an alert so that staff can handle the situation.
This parking meter system significantly reduces human error and costs while improving data accuracy and reliability.
