In recent years, the continuous development of science and technology , so that the field of industrial automation innovation. But for China's coal industry is still little progress in related fields , and even almost stagnant. On the market for the coal industry related industrial automation products rarely . Especially in the many underground coal mines operating environment , operating machinery and methods are very traditional manual operation, lack of network digitization scheduling control , manual operation for the entire production of transport bring great danger , greatly reducing the production efficiency. This issue is related to a combination of developments in the field of domestic trends to project team cross-cutting project \explosion network turnout control system. From the host computer through the Ethernet ring network subnets access PLC control mine turnout achieve switchman system digitization, electrification and network transformation . This article from the system's overall design , communication theory and specific design to introduce two subsystems . In communication theory on a comprehensive comparison of the two communication protocols TCP / IP and UDP / IP protocol advantages and disadvantages , while taking advantage of the multi- ring network topology design to achieve system redundancy , and the particularity of the work environment according to the system introduced the system explosion of research . In the overall system design implementation section through C # and kingview implemented in two ways to complete the system set-up and expansion of the concrete implementation of the project offers a variety of programs available for reference . In the PLC subnet important consideration practicality of the system , the laying of a master - slave form of network model, covering underground fiber can not be covered in some blind spots , and improve the whole system . Finally the design for the entire system are summarized.
