The Study Of Adjusting Flat Systems Of Bituminous-Concrete Pavers

The bituminous concrete paver is the main mechanical equipment carrying on the pitch and paving the homework, the quality of controlling systematic function is a key factor of evenness of road surface paved out to determine the system of the making level automatically of paver. The study in this respect had just started, had introduced the model produced and been selected from hydraulic pressure system and automatically controlled system which produce by other country, adopt a whole set of mode totally imported. In February of 2002, regarded intellectual paver as the first key product to develop and promote with technology in the 863 Program project for the country launched formally , the control system is an important component in the control system of the paver to making level automatically. So, the research of this project has very remarkable social benefit and economic benefits. Go through control the forms on automatically it make level control system from switch the automatic control systems , make level commonly control system, proportion expression automatic control system automatically to now finally for every one than Evolution of the pulse type automatic control system . In making level the evolution of the control system automatically, most previous pavers adopt the control method of the switch, sensor its mostly hydraulic pressure person who move at the same time (transfer valve to), With electronic sensing development and extensive application of technology , appear electric potential device angle sensor , ultrasonic sensor and laser sensor , etc. Sensor of type gradually, cooperate with the correspondingpulse to regulate the way and realize the proportion at the same time---Controlmethod of the pulse. These kinds of sensors each have their own pluses and minuses , use in the paver at home and abroad at present. Several factors of the precision of the control system that this text influences making level automatically through analysing, in making level the systematic foundation floating and looking for plain paying attention to and dynamics and analysing, utilize computer artificial technology smooth , fast settlement making level variety ,...
