Abstract This paper introduces an innovation design of flow control system for hydraulic elevators with car speed feedback. By measuring pulse signal emitted by photoelectric encoder mounted on the elevator car, a single-chip computer controls the electrohydraulic proportional integrated flow valve, then drives the elevator car by a hydraulic cylinder. With this set of single-chip computer control system, good speed performance of the elevator can be achieved. Furthermore, it has strong robustness against the disturbance of oil temperature variation, mechanical friction and other disturbance factors. In order to obtain better ride comfort and soft start of the elevator, PID control algorithm is also proposed. Some mathematical models both for static and dynamic states have been established, consequently simulation results are found to be in close agreement with the experimental results.

Photoelectric Sensor

The garbage salvage ship is made from polystyrene plastic as hull framework and STC89C52 single-chip microcomputer to control the core, and consists of DC gear motor, photoelectric sensor, power circuit and other circuits. The system uses STC89C52 to control the boat to move forward, backward or turn through the I/O port. Tracing is finished by infrared obstacle avoidance sensor E18-D80NK. Working manner of the infrared obstacle avoidance sensor E18-D80NK was introduced and its application scheme based on STC89C52 single-chip microcomputer in the control system of garbage salvage ship was put forward.
