For the oil spill and inaccuracy of position adjustment control of planes hydraulic jack, thisgroup design a novel electric machinery jack. A novel intelligent jack control system, whose main chip is C8051F410, is developed according its strong demand for handling.This system, which mainly powered by stepping motor, realized the control of jacks movement such as fast walking into the workFast walking into the workafter workafter controlling multiple stepping motor. This measurement system also accomplished real-time acquisition and display for the height displacement signal during operation and load force signal of key parts of jack such as supporting arm.The hardware parts are consist of stepping motor, driver, controller and measurement system based on C8051F410. In the jack’s movement control: including the body of workers into the top, no-load driving fast and Jack at the bottom of the car through the horizontal direction of the implementation of the horizontal movement and the horizontal fine-tuning。 In stepping motor’s controller, By using the host computer, the parameters of the controller are set well in advance, and the operation interface can be controlled and operated by all kinds of buttons in the operation process;In the measurement of analog signal, Pull pressure sensor and pull wire type displacement sensor output signal through the main control chip data processing and data conversion, data real-time display in the control interface, and can be through the main control chip preformed serial port to realize data exchange with the host computer。 In the control interface, 1.3 meters above the body of the jack design manual control display box, realizes the jack at the bottom of the car forward and backward, the horizontal adjustment and no-load rise of control, and can display the height displacement data; in operation personnel capable of observation to the position of the aircraft fuselage design of the integrated control and collection box, by stepper motor controller serial communication port of the synergistic control of three jack heavy load driving, and can show through pull pressure sensor for measuring the loaddata.Four series DC 24V batterys supply the electric for the system, thus satisfy the demand for different voltage of each element. This paper accomplished the basic movment control of jack, circuit manufacturing and soft debugging of measurement system. This novel plane mechanical jacks prototype has been tested its function inShaanxi Hanzhoung factoryShaanxi Hanzhoung factory, the result shows that most functions has been achieved.
