The characteristic of ETCP parking is that it can automatically identify the license plate without taking a card, and then pay directly online, without stopping, opening windows and opening confidential payment. It's really fast. Don't waste a lot of time. Anyway, I think ETCP parking is good.
ETCP parking principle:
1. When the owner stops and enters the parking space, the ground sensor can sense that there is a car coming in and send the IN information to the concentrator (note that the sensor can only recognize whether there is parking, and will not know the license plate number).
2. The concentrator sends the parking space number, state time and other data to the monitoring backend; The monitoring back-end uses this number to record the use status of the parking space and start timing.
3. The owner client uses APP software to register the berth number and prepaid time, and sends it to the monitoring backend, which corresponds to the recorded data in the backend database.
