Research on Automatic Control System of Suspended Access Platform Based on PIC16F877A

The design of automatic control system mounted on the suspended access platform is put forward. With advantages of the microcontroller in real time data acquisition and data processing, PIC16F877A is applied as controller of the system. Angle sensor and pull sensor are applied as measuring elements of the system. The control system can implement functions of automatic leveling and overload protection. The new automatic control device is tested to be easy to operate and high reliability. It completely meets requirements and suits for multi-series specifications suspended access platforms, worth to be widely extended in applications.
