基于近距离通信的站台门控制新方案

New Control Scheme of Platform Screen Door Based on Short-range Communication

首先分析了基于通信的列车控制系统中现行车门与站台门联动方案存在的主要问题;其次,通过对所发现问题的分析,提出了基于近距离通信的全新解决方案;进而,结合联动运营场景和现场应用环境以及各种近距离通信技术的特性,对新方案的关键技术进行了选择,并完成了新方案装置的初步设计。通过理论分析得出,新方案不仅解决了现行方案中存在的所有问题,还在可靠性及实时性方面相比现行方案有较大的改善。最后,使用CPN-Tools工具,对新方案系统进行数学建模及状态空间分析。分析报告的结论验证了新方案系统的正确性。

Firstly,the main problems existing in current train door and platform screen door linkage based on CBTC(communication based train control)system are analyzed.Secondly,through an analysis of above-mentioned problems,an innovative solution based on close-range communication is proposed.Thirdly,combined with the linkage operation scenario,the field application environment and characters of various close-range communication technologies,a key technology for the new scheme is selected and the preliminary design of which is completed.The theoretical analysis shows that the new scheme can not only solve all the problems existing in current schemes,but also improve greatly the reliability and real-time performance.Finally,mathematical modeling and state space analysis of the new scheme system are carried out by using the CPN(coloured petri nets)tools.The conclusions of the analysis has verified the correctness of the new scheme.
