2. Parking system based on earth magnetism + handheld toll collection instrument
The mode is an auxiliary scheme for solving fee evasion by a parking meter, namely after a car owner parks the car, the car is judged to be parked by geomagnetism, and if no payment is carried out for 15 minutes, a penalty ticket is issued by law enforcement personnel. The defect is that the detection range is not easy to debug; the road needs to be broken; signal transmission instability (car shields part of the signal); the influence of road surface deformation seriously causes frequent water leakage maintenance; the system has a single charging function, so that evidence cannot be complained, and disputes are easy to occur; charging requires manual additional recording of vehicle information.
3. Parking system based on high-position camera
The method is that a camera rod with three meters is erected at the roadside, 4-6 parking spaces are monitored in an image mode, and an uploading system is used for automatic fee settlement. The system has the disadvantages of complex equipment installation, high space requirement, long installation period, circuit breaking, net pulling and electricity pulling construction cost; the vehicle entering and exiting condition is judged non-physically, the misjudgment is high, and manual or geomagnetic auxiliary judgment is needed; is seriously affected by haze; the communication flow is large, and the power consumption is high; the installation environment requirement is high, and the suitability is poor.
