Moving - block signaling system indicates the development tendency of urban rail transit signaling system 移動(dòng)閉塞是城市軌道交通信號(hào)系統(tǒng)的發(fā)展方向。
Kernel signal handling is rather elaborate , because the posix semantics allows processes to temporarily block signals 內(nèi)核信號(hào)處理是很復(fù)雜的過程,因?yàn)閜osix信號(hào)語義允許進(jìn)程臨時(shí)禁止某些信號(hào)的接收。
The paper examines the principles of communication based moving - block signaling system , its typical structure and its practical methods 本文討論了基于通信的移動(dòng)閉塞信號(hào)系統(tǒng)的原理、典型結(jié)構(gòu)和實(shí)現(xiàn)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對(duì)象中返回信息的函數(shù),或者如果它每次使用時(shí)都會(huì)阻塞信號(hào),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 在此基礎(chǔ)上,對(duì)廣州地鐵四號(hào)線信號(hào)系統(tǒng)的選擇進(jìn)行了探討,指出了廣州地鐵四號(hào)線直線電機(jī)運(yùn)載系統(tǒng)采用移動(dòng)閉塞技術(shù)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 在啟動(dòng)一個(gè)電傳打字機(jī)系統(tǒng)中,迅速領(lǐng)先字符信號(hào)或閉塞信號(hào),并且準(zhǔn)備好接收設(shè)備為接收代碼元件的信號(hào)元件的有效狀態(tài)。
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 信號(hào)系統(tǒng)是確保城市軌道交通列車運(yùn)行安全及提高運(yùn)營效率的關(guān)鍵設(shè)備。本文詳細(xì)討論了應(yīng)用于城市軌道交通的先進(jìn)的信號(hào)系統(tǒng)? ?列車運(yùn)行自動(dòng)控制系統(tǒng)( atc )的組成和結(jié)構(gòu),對(duì)其三個(gè)子系統(tǒng):列車自動(dòng)監(jiān)控系統(tǒng)ats 、列車自動(dòng)保護(hù)系統(tǒng)atp 、列車自動(dòng)運(yùn)行系統(tǒng)ato的功能和分類進(jìn)行了詳細(xì)分析和比較。
