Cloud platforms use netty to connect with lock boards, long connections to maintain communication, and connection pools to access database management to ensure data can be checked and server load can be easily observed. All system connections are encrypted using private protocols to ensure data security;

The parking lot lock panel terminal regularly sends a heartbeat package to the server. The heartbeat package uses a short connection. The contents are: machine status, all parking status;

Real-time data upload via short connection after vehicle departure, transaction update, cash payment, forced exit; The system periodically uploads non-uploaded transaction data;

Lock panel system and entrance and exit parking management system use unified transaction data fields to ensure data consistency and enhance the operability of the unified platform.

Lockpad control commands, network payment information returns, and other real-time operations require a long connection for communication.

For parking lots without clearing machine, cloud platform queries parking information when paying fees, calculates fees in cloud platform, and all fee payment (Alipay, WeChat, coupons) is completed on cloud platform. When customer payment is completed, cloud platform notifies the lock system to unlock and release;
