Abstract
With the rapid industrial development, programmable logic controller (PLC) is extremely rapid development in recent years, the application of the expansion is at the core microprocessor, the computer-technology, automation technology, communications technology and the integration of common industrial control For. It is fully functional, easy to use, easy maintenance, high universality, reliability, cost-effective high, the industry has been in extensive use in the field of control, industrial automation become a powerful tool. Since the PLC logic of a strong, easy to use, high reliability, are often used as a field data collection and control equipment. Configuration software has a good monitoring performance, and the PLC through a combination of equipment is to achieve "intelligent" means of control.
The design on the exchange of mine hoist the work process and introduced a PLC-based control hoist the configuration process.
PLC control system on the hardware structure, working principle PLC control system design and the basic principles and steps to control the configuration of exchange mine hoist the operation as an example to illustrate PLC in the production process the application. According to the design of the equipment requirements of production control and automatic control of the electrical lines, including equipment Commitment, the status signals, signals and signal failures, such as acquisition. In accordance with the requirements of the final design of PLC control systems, including the Selection PLC, the system of resource allocation and the sewage treatment process in accordance with the procedures for the preparation of PLC.
