Moving - block signaling system indicates the development tendency of urban rail transit signaling system 移动闭塞是城市轨道交通信号系统的发展方向。
Kernel signal handling is rather elaborate , because the posix semantics allows processes to temporarily block signals 内核信号处理是很复杂的过程,因为posix信号语义允许进程临时禁止某些信号的接收。
The paper examines the principles of communication based moving - block signaling system , its typical structure and its practical methods 本文讨论了基于通信的移动闭塞信号系统的原理、典型结构和实现方式。
Or any other function that returns information in the same object , or if it always blocks signals around each use , you re safe 或者任何其他在同一对象中返回信息的函数,或者如果它每次使用时都会阻塞信号,那么就是安全的。
Then it discusses the signaling system in guangzhou metro line no . 4 and points out the necessity and possibility of adopting the moving - block signaling technology for its linear motor carrying system 在此基础上,对广州地铁四号线信号系统的选择进行了探讨,指出了广州地铁四号线直线电机运载系统采用移动闭塞技术的必要性和可行性。
In a start - stop teletypewriter system , the significant condition of the signal element that immediately precedes a character signal or block signal and prepares the receiving equipment for the reception of the code elements 在启动一个电传打字机系统中,迅速领先字符信号或闭塞信号,并且准备好接收设备为接收代码元件的信号元件的有效状态。
This paper describes the components and structure of advanced signaling system : automatic train control system ( atc ) , analyzes the function and classification of its three subsystems : ats , atp and ato , with emphasis on currently widely adopted atc system - quasi - moving - block signaling system , which works on coded digit track circuit , and discusses the operating principles of coded digit track circuit and the features of train control of quasi - moving - block signaling system 信号系统是确保城市轨道交通列车运行安全及提高运营效率的关键设备。本文详细讨论了应用于城市轨道交通的先进的信号系统? ?列车运行自动控制系统( atc )的组成和结构,对其三个子系统:列车自动监控系统ats 、列车自动保护系统atp 、列车自动运行系统ato的功能和分类进行了详细分析和比较。
