新型分布式全电子计算机联锁系统

以联锁机为核心的集中控制方式是目前计算机联锁系统的主流,但该方式存在风险集中,工程造价较高,系统维护困难等问题。随着计算机、控制和通信技术的发展,分布式控制结构的优势日益突显。为了进一步提高系统的可靠性、安全性和灵活性,引入区域控制的概念,并将其与分布式控制、智能控制等技术相结合,在符合计算机联锁技术条件的基础上提出了一种新型的分布式全电子计算机联锁结构。给出了该计算机联锁系统中区域控制器的模型,对其联锁功能、网络结构进行了详细介绍。该结构实现了地理上和功能上的分散控制,有效降低了系统风险,符合铁路信号故障-安全的要求。

Novel Pattern of Distributed All Electronic Computer Interlocking System

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.
