The Motor Truck Quantitative Automatic Loading System Design And Implementation

With the development of society, more and more requirements efficient, fast, accurate loading transport in the field of coal sales. The shipment of coal is an important sign of the degree of modernization in the coal industry. On the one hand automation achieve loading can improve the loading speed, enhance the ability of Sinatra's. On the other hand the use of quantitative real-time automatic control system loading can solve various problems arising in the process and reduce the resulting economic losses.This paper's motor truck automatically loading system is used in sales system. It uses the existing hydraulic system which is used to automatic feed and it through controlling the hydraulic system and position limits witch finally according to the specific situation appropriate changes the gate opening size to control the loading time, and then achieve a certain loading precision.This system uses the Siemens S7-200 series programmable logic controller (PLC) to realize the whole load process automatic control. It can be reliable and accurate real-time monitoring and record the load process of operation condition, and has the query, alarm, redundancy, and other functions. Practice proves that this system is convenient to install and use, and through using the system loading efficiency is improved, reliability and loading precision is higher, and it strong adaptability and can be flexible extension. This system can be widely used in coal mine enterprises or factories such as powder or sell small granular materials sales system.The main contents are:Explanation of automatic loading system control program; design the hardware connection of automatic control loading system; write the PLC program automatic loading system and commissioning;...
