V. CONCLUSION
The OPC Data Access Server designed in this paper achieves real-time data reading and writing, so it has great practical value. The software of the control system can make data access to the hardware effectively and steadily, and the information exchange between application software is also flexible, which greatly improves interoperability and adaptability of the control system.
The control system has been used in water spray cooling system of Jigang Group Co.,Ltd. NO.4 blast furnace gas pipeline, practical applications prove that the system can display the working site operation data timely and accurately, and it has achieved a good function to reduce the gas temperature.
