Novel Pattern of Distributed All Electronic Computer Interlocking System
新型分布式全电子计算机联锁系统

Nowadays, the centralized control mode with the interlocking computers as its core is the main trend of the current computer interlocking systems, however, this type of control mode always induces many problems such as centralized risks, higher project costs, and difficult tasks of system maintenance. As the development of computer, control and communication technology, the advantage of the structure of the distributed control mode is highlighted increasingly. In order to improve the reliability, security, and flexibility of system furthermore, by introducing the concept of field control （FC） which was combined with other techniques such as the distributed control and intelligent control in this study, we proposed a novel pattern distributed general electronic computer interlocking system on the basic of requirements of computer interlocking technology. We presented a model of the field controller in the computer interlocking system and made detailed instructions about its interlocking function and network structure. The structure achieved the decentralized control geographically and functionally, and it reduced the system risk effectively and agreed with the requirements of the fault-oriented security principle.
