摘要
北京城市轨道交通计算机联锁控制系统要求具有扣车、紧急关闭和轨道区段故障时单独操纵道岔三种特殊联锁功能。确定A,B两种类型的矩阵,建立新的模型和算法,实现扣车时单独操纵道岔这种新增加的特殊联锁功能。利用原有联锁运算模块中的某些算法,实现紧急关闭时单独操纵道岔特殊联锁功能。在原有联锁运算模块中的某些算法上稍加修改,实现轨道区段故障时单独操纵道岔特殊联锁功能。实现三种特殊联锁功能的软件满足技术条件要求和故障—安全性的设计原则。
Some special interlocking functions are required to be added to the computer interlocking control system used in Beijing urban rail transit such as train detaining, emergency closing and independent operation of turnout in case of track section failure. The newly added special interlocking function as independent operation of turnouts while train detaining can be realized by determining A, B types of matrices and establishing brand-new models and algorithms. By using some of the algorithms in the original calculating models for interlocking, the special interlocking function as independent operation of turnouts when emergency closing can be realized. By slightly modifying certain algorithms in the original calculating modules for interlocking, the special function of independent operation of turnouts in case of track section failure. The software realizing 3 special interlocking functions can meet all the demands of the relevant technical requirements and the fail-safe design principle.
