Abstract

The invention discloses a long-span double-platform automatic leveling control system which comprises two platforms on one vehicle body, a pressure sensor used for monitoring the pressure state of a leveling oil cylinder, double-axis sensors used for respectively detecting the inclination angles of the two platforms, a main control unit electrically connected with a display unit through an RS232 bus, a multi-way valve control panel connected with the main control unit in series, and a proportional multiple directional control valve group electrically connected with the multi-way valve control panel, and forms a decentralized control system, wherein the main control unit sends a control command through a display and the RS232 bus communication, adopts a main control panel as the control hub, analyzes the control command, and sends the analyzed control command to the proportional multiple directional control valve group through adopting the multi-way valve control panel distributed in series as an output amplifier stage, and the final action is achieved through the leveling oil cylinder; during the action process, the double-axis sensors monitor the angles of the two platforms in real time, and are communicated with the multi-way valve control panel and the main control unit through a CAN bus. According to the long-span double-platform automatic leveling control system, the problem that the two platforms are difficult to level at the same time is solved.

Description

technical field [0001] The invention relates to an automatic leveling control system with a long span of more than 3800 mm and two platforms, especially a leveling control system for special vehicles with precision requirements for leveling. Background technique [0002] The automatic leveling system is mainly used for the automatic leveling of special vehicles, and can also be applied to the automatic leveling of other ground equipment. Usually, under extreme working conditions, the vehicle platform must be able to withstand the overturning moment caused by wind resistance. At the same time, the leveling time is required to be as short as possible, and the horizontal accuracy must be maintained within a certain period of time when performing tasks. After the car platform is leveled, there must be no soft legs. There are several options for the support of the leveling system, such as three-point support, four-point support, and six-point support. The three-point support le...
