The Study Of 4-coke Oven Control Systems And Wireless Communication

In this article, it is about the combination for every unit in 4-Main-Coke-Oven-Vehicles which are Coke Chargers, Coke Pushers, Coke Guides, and Dry Quenchers etc. It introduces briefly about the interlocking control and automatically working control conditions, components and application of systems of 4-Main-Coke-Oven in this article. It uses SIMATIC S7-400 H PLC、WINCC V6.0、MASTERDRIVES 6SE70 converter and SCALANCE W products in control systems and network structures in Oven. And it shows the success of the key function in software and hardware designs.There are two basic technical problems we need to solve first as follows, for making the dynamically automatic oven number distinguishing of Coke-Oven-Vehicles and spotting control system, decoking and interlock control, charging and interlock control in all four vehicles: The position locating; And, the data communication. It is always be used as the combination with both locating and communicating technologies for controlling all four vehicles in the whole world.Locating the coding cables suits the best for the climate of coking among all locating technologies. It has the high precision of locating, and the conditions of moving vehicles in the coking process. And most important, it is stable.Siemens is the standards wireless product based on IEEE 802.11 g for the data communications. It achieves the inductive wireless technology and wireless broaden-frequency communication.PLC control technology, locating coding cables technology and wireless broaden-frequency communication technology bring our system to succeed the control of all four vehicles and their function of combination for improve the real-time, reliability and maintainability. They make a large profit for high location precise, low error-code occurring, high-speed communication, little atypical element, simple equipment, modern designs, and multiple functions etc.
