Station telegraph code is a realization in the station by the corresponding forward or overlay track circuit lootive railway traffic signal information to ensure the safety of important technology. The design of the station selected ZPW2000A Automatic blocking system and implement prestack. ZPW2000A type can effectively solve tuning off the track inspection zone, reducing the dead zone length tuning distinguish path and to realize the disconnection fault checking of the tuner unit, to improve the transmission length of the track circuit, the track circuit more stable. During operation, the train must be received continuous ground lootive signal information transmitted, so the use of prestack electrical code technology to reduce lootive off the yard phenomenon.The engineering design of the sectionbysection presuperposition coding by ZPW2000A on station (up traffic) prises a total of 10 drawings:the station signal layout,the station upward positive and forward line receiving piecewise approach pre superimposed coded circuit diagram,the station upward positive and forward line departure piecewise approach pre superimposed coded circuit diagram,the station stock road (IIG, 4G) coded circuit,the station frequency shift within the cabinet equipment layout, the station consolidated rack equipment layout, the station rack equipment layout within the portfolio, bined with automatic blocking upstream circuit,carried out on the 10 drawings drawings illustrate to the station upward departure piecewise approach superimposed precoded circuit, for example, the station N+1 redundancy within the circuit and the upstream grid approach coded circuit introduces the station upward departure into the path of the excitation circuit and CJ autistic circuit, low frequency encoding circuit, XFMJ excitation circuit and selfclosing circuits.The engineering design of the sectionbysection presuperposition coding by ZPW2000A on station is designed under the construction design and specification of railway signaling and it meets the requirements of the Railway Signaling Design Specifications (TB100072006) and Cab Signaling Message Define and Allocation (TB/T30602002).Key Words: ZPW2000A, Sectionbysection presuperposition, Coding 目 錄摘 要 IAbstract II目 錄 III1 緒論 1 工程背景 1 主要設(shè)計技術(shù)標(biāo)準(zhǔn) 1 主要設(shè)計內(nèi)容 22 信號平面布置圖 3 軌道電路區(qū)段的劃分 3 載頻配置 3 股道有效長度 4 鋼軌絕緣節(jié) 4 道岔類型表 53 設(shè)備布置圖 6 17號站站內(nèi)移頻柜設(shè)備布置圖 6 17號站站內(nèi)綜合柜設(shè)備布置圖 6 17號站站內(nèi)組合架設(shè)備布置圖 74 17號站上行正線正向接、發(fā)車進(jìn)路逐段預(yù)疊加電碼化電路圖 8 17號站上行正線正向接車進(jìn)路逐段預(yù)疊加電碼化電路圖 8 17號站SJMJ上行接碼繼電器 8 17號站上行正線正向接車CJ傳輸繼電器 8 17號站上行正線正向接車低頻編碼電路 9 17號站上行正線正向發(fā)車進(jìn)路逐段預(yù)疊加電碼化電路圖 10 17號站SFMJ上行發(fā)碼繼電器 10 17號站上行正線正向發(fā)車CJ傳輸繼電器 11
