The invention discloses a method for automatically judging a protection section limiting point and turnout locking, which comprises the following steps of: processing collected laser fixed measurement data of trackside equipment, screening out an accessible signal machine with the protection section limiting point, identifying the protection section limiting point, judging the type of the limiting point, then establishing a protection section limiting point judgment model, and judging the turnout locking according to the protection section limiting point judgment model. Real-time difference comparison and updating are carried out, and whether the protection section limiting points meet the design requirements or not is judged; analyzing the turnout and the warning sign, identifying axle counters nearby the turnout and the warning sign, calculating to obtain the distance between the turnout and the warning sign in the backward sliding direction of each train and the axle counters nearby the turnout and the warning sign, establishing a turnout locking state judgment model, performing real-time difference comparison and updating, and judging whether the turnout locking state meets design requirements or not; and finally obtaining a judgment result. According to the invention, only according to the collected laser fixed measurement data, automatic updating of the protection section limiting point and the turnout locking state can be carried out, and whether the design requirements are met or not is automatically judged.

    本发明公开了一种自动判断保护区段限制点和道岔锁闭的方法,是对采集到轨旁设备的激光定测数据进行处理,筛选出具备保护区段限制点的可接近信号机,识别其保护区段限制点,并判断限制点类型,然后建立保护区段限制点判断模型,进行实时差异比对及更新,判断保护区段限制点是否符合设计要求;再对道岔和警冲标进行分析,识别其附近的计轴,计算得到每一个列车后溜方向上道岔和警冲标与其附近的计轴间的距离,再建立道岔锁闭状态判断模型,进行实时差异比对及更新,判断道岔锁闭状态是否符合设计要求;最后得到判断结果。根据本发明,只需根据采集的激光定测数据,则可进行保护区段限制点和道岔锁闭状态的自动更新,并自动化判断是否符合设计要求。
