一种基于RS485的电梯通讯方法
By improving the RS485 polling mechanism, the current floor and the next floor of the elevator are queried in real time, and call button commands are processed with priority. This solves the problem of elevator response delay in high-rise buildings and improves the safety and response speed of elevators.

AI Technical Summary
The existing RS485 polling mechanism causes excessive delays in receiving operation commands from the elevator mainboard in high-rise buildings, posing a safety hazard and failing to meet the real-time requirements of elevator operation.
By improving the existing polling mechanism, the system queries the current floor in real time and prioritizes the processing of elevator call button commands to promptly open the door; it also queries the next floor in real time and prioritizes the processing of elevator call button commands to ensure the flexibility of interception in the same direction while the elevator is running at high speed.
It enables real-time response of elevators in high-rise buildings, avoids the risk of passengers being trapped in the doors, improves the success rate of interception during high-speed elevator operation, and reduces interception failures caused by communication delays.
