摘　　要：为应对移动闭塞、市域铁路股道有效长缩短、国外安全规范等新要求对联锁技术提出的挑战,结合国内外信号系统相关技术发展和安全需求,提出计算机联锁技术的应对方法与思路。按移动闭塞理念对传统进路进行分解组合,以提高车站内列车运行追踪能力;按延续进路思路开展过走防护区段的安全防护,与列控系统接口提高进路解锁效率并及时回缩进路授权;分析对比侧防需求与目前我国联锁技术条件的本质差异,对侧防设置的必要性进行综合评估;提出联锁产品当地化应用时,信号接近控制需要关注和思考的问题。为联锁技术的进一步发展和更广阔的应用提供思路和借鉴。In order to respond to new challenges of interlocking technology posed by new requirements such as the moving block,shortening the effective length of tracks in suburban railway,foreign safety specifications,combined with the technology development and safety requirements related to signal systems at home and abroad,the responding method and thoughts of interlocking technology are put forward.It provides traditional route separating and combining method according to the moving block conception in order to improve the train operation tracking capability in station area,and the safety protection of overlap section is carried out according to the idea of the successive route to improve the route release efficiency and retract authority in time by interfacing with the train control system.Analyzing and comparing the flank protection requirements and the basic differences with our current interlocking technical specification,the assessment of the necessity to set the flank protection function is proposed.Then it provides the key points need to think relative to the approaching control of interlocking system in oversea local application.All of these provide the technology thought and reference to the interlocking technology new developing and more application.
