TranslatedParking lot system source code, new energy charging pile system, parking lot mini program, smart parking, Parking system. [Feature introduction]: ① Compatible with many mainstream cameras on the market; in theory compatible with all hardware, and flexibly extensible. ② After a camera recognizes a plate, the data is automatically uploaded to the cloud and recorded; the camera's unique id and hardware serial number are verified to prevent illegal data entry. ③ Users can check parking record details on their phones and pay fees themselves (supports WeChat, Alipay, and bank interface payment; each parking lot can be assigned a different merchant to collect payments). After payment, the barrier gate lifts automatically on exit within the free time. ④ Supports searching for nearby parking lots in the app (navigation, number of available spaces, parking fees, coupons, ratings, reviews, etc.), and parking spaces can be reserved. ⑤ During a power outage or network outage, booth attendants can use the app to take over the hardware and enter parking records. [Technical architecture]: The backend is developed in Java, with the frameworks oauth2 + springboot2 + dubble (Dubbo); databases are mysql/mongodb/redis; the underlying instant messaging framework is netty4; Android and iOS are both developed natively; the admin backend template is a professionally customized vue one.
