speed and the continuous development of the railway undertakings to meet lootive at the station via rail lootives frequency shift signal received requests for information, the station track circuit must be implemented telegraph code. 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(jì)技術(shù)標(biāo)準(zhǔn) 1 主要設(shè)計(jì)內(nèi)容 22 信號(hào)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(zhǎng)度 4 鋼軌絕緣節(jié) 4 道岔類型表 53 設(shè)備布置圖 6 17號(hào)站站內(nèi)移頻柜設(shè)備布置圖 6 17號(hào)站站內(nèi)綜合柜設(shè)備布置圖 6 17號(hào)站站內(nèi)組合架設(shè)備布置圖 74 17號(hào)站上行正線正向接、發(fā)車(chē)進(jìn)路逐段預(yù)疊加電碼化電路圖 8 17號(hào)站上行正線正向接車(chē)進(jìn)路逐段預(yù)疊加電碼化電路圖 8 17號(hào)站SJMJ上行接碼繼電器 8 17號(hào)站上行正線正向接車(chē)CJ傳輸繼電器 8 17號(hào)站上行正線正向接車(chē)低頻編碼電路 9 17號(hào)站上行正線正向發(fā)車(chē)進(jìn)路逐段預(yù)疊加電碼化電路圖 10 17號(hào)站SFMJ上行發(fā)碼繼電器 10 17號(hào)站上行正線正向發(fā)車(chē)CJ傳輸繼電器 11 17號(hào)站上行正線正向發(fā)車(chē)低頻編碼電路 125 17號(hào)站站內(nèi)電碼化其他電路圖 13 17號(hào)站股道電碼化電路圖 13 17號(hào)站正線IIG電碼化 13 17號(hào)站側(cè)線4G電碼化 14 17號(hào)站站內(nèi)電碼化N+1冗余電路 15 電平級(jí)別和載頻切換 15 低頻切換電路 16 發(fā)送通道切換電路 17 17號(hào)站自動(dòng)閉塞結(jié)合電路 17 接近軌道繼電器電路 17 離去軌道繼電器電路 18結(jié) 論...................................................................................................................................19致 謝 20參考文獻(xiàn) 21 III 1 緒論 工程背景隨著我國(guó)經(jīng)濟(jì)建設(shè)的飛速發(fā)展,鐵路運(yùn)量徒增,行車(chē)密度和速度不斷提高,安全與效率的矛盾日益尖銳,原有的車(chē)站正線電碼化技術(shù)已經(jīng)不能適應(yīng)運(yùn)輸?shù)男枰?,必須在現(xiàn)有基礎(chǔ)上進(jìn)行相應(yīng)的改造以及更新。在運(yùn)行過(guò)程中列車(chē)必須要連續(xù)不斷的收到地面發(fā)送的機(jī)車(chē)信號(hào)信息,故采用預(yù)疊加電碼化技術(shù),以減少機(jī)車(chē)掉碼現(xiàn)象。蘭州交通大學(xué)畢業(yè)設(shè)計(jì)(論文)摘 要隨著列車(chē)的提速與鐵路事業(yè)的不斷發(fā)展,為滿足機(jī)車(chē)在站內(nèi)能通過(guò)軌道接收到移頻機(jī)車(chē)信號(hào)信息的要求,站內(nèi)軌道電路必須實(shí)施電碼化。ZPW2000A型可以有效的解決調(diào)諧區(qū)的斷軌檢查問(wèn)
