自动化设计（Automation design） Electromechanical automatic leveling control system of vehicle borne radar Source: Mobile land surface carrier, such as vehicle borne radar antenna, launcher and so on, after reaching the predetermined position, requires the rapid erection of accurate horizontal datum. Automatic adjustment of electromechanical and hydraulic automatic leveling compared with short leveling time, high leveling precision and high reliability [21 the subject of a vehicular radar original leveling control system for a comprehensive transformation, realize the automatic leveling of the automatic closed loop control electromechanical vehicle platform. 1 system leveling program The automatic leveling system consists of 4 sets of legs, 1 sets of horizontal sensors and 1 sets of control boxes. The support leg is composed of servo motor, ball screw and gear reducer with photoelectric encoder; level sensor with dual axis electronic level monitor; the control box consists of 4 sets of legs motor driver, low voltage power supply, interface conversion board, state display, PLC controller, relay, temperature controlled heater, fan and other electrical device protection switch. 1.1 leveling method The X axis and the Y axis of the work platform supported by the four points are two mutually perpendicular to each other on the working platform surface according to the installation position of the horizontal sensor. The adjustment of a plane to the horizontal state of the adjustment process, there can be one-way adjustment and multi-point regulation of the two programs. If multi-point adjustment is adopted, each point moves at the same time and is adjusted to a predetermined point. It is characterized by high speed but complex algorithm. Due to the four point support platform is a rigid structure, the balance in the indeterminate state, multi point adjustment due to displacement, each of the support legs are not the same speed, the four legs of the movement of mutual restraint, t
