Study Of The Automatic Leveling Control System Based On MCU

With the rapid development of the highway traffic construction, it is getting higher and higher to the road surface smoothness request. The original manual control machinery far cannot satisfy the request, but provided the advanced electronic intelligence operating system on the existing machinery already to become the mainstream. This thesis analyzes the control mode of the grader leveling system and the working principle of all kinds of automatic leveling system at home and abroad, comparing the two key non-contact automatic leveling control system: laser leveling technology and ultrasonic leveling technology, and doing a detailed analysis of the ultrasonic sensor. For the ground-work in the whole process of manually-not the accuracy, put out the control programme of the automatic leveling control system based on MCU. Choosing a production of Honeywell Corporation 943 series of ultrasonic sensors for surface data acquisition and the 8051 MCU as a digital controller of the microcontrollers, completed the automatic leveling control system hardware design and software design. Through the experiment, the controller of the system stability testing, performance testing and anti-jamming function tests are validated. The results show that the system is running well, can significantly improve the smoothness of the road. By the study of the automatic leveling control system based on MCU, it is laid the foundation of the multiple function and high reliability automatic leveling control system study.
