Design of the C8051 microcomputer-based control system of hydraulic elevator

This paper presents the C8051 series microcomputer used in hydraulic elevator control system with velocity feedback. The hardware and software technologies are described. The system can collect the running data of the hydraulic elevator car automatically, control the running status of the elevator, display the parameters of its running and debugging, and draw curves of elevator running. All these functions are supposed with the database. This results in good dynamic and static characteristics, stability in temperature and anti-interference ability of the elevator. This control system may also be used in similar fluid system.
