Control System of Sand Milling Collection Machine Based on PLC

Abstract:

An engineering machine wireless control system is researched based on a diggings milling collection machine. The system consists of PLC, communications module, relays, touch screen, router and long-distance terminal. The ideas of PLC state of self-sustaining when host dropped, wireless control and local control redundancy, and control instructions prioritization are proposed to achieve the reliable operation of the system. The system with local control and wireless control has been applied on the sand milling collection machine and the wireless remote control of all operations has been realized with no instruction lost and misused. A mining engineering requires that the sand with the mine in the earth’s surface of about 2~5cm depth should be collected. Also, in order to realize the accurate collection to reduce the subsequent processing cost, it demands that the thick precision of the collection should be controlled within ±5mm. Considering that the milling collection is suitable for work of large-area sand collection and easier to meet the demand of the accurate control of the depth, the sand milling collection machine is researched. This machine is equipped with the milling collection unit and depth control system. It is able to conduct the sand collection experiment under the field condition.
