【摘要】：我國鐵路經(jīng)過六次大提速,使得列車的行駛速度越來越快,運行間隔時間越來越短,增加了鐵路的運輸能力,對我國的國民經(jīng)濟的發(fā)展起到了巨大的促進作用。列車速度的提升對區(qū)間信號設備的依賴也越來越強。區(qū)間信號設備的正常運行變得尤為重要,但是鑒于當初設計系統(tǒng)時受資金和技術的影響,使得對于室外設備(諸如信號機和軌道電路)的監(jiān)測太少。據(jù)統(tǒng)計目前信號設備的故障大多數(shù)發(fā)生在室外,而集中監(jiān)測系統(tǒng)是在室內(nèi)采集的信號,無法反映區(qū)間信號設備在室外的真實運用狀態(tài)。當室外信號設備發(fā)生故障時,使得電務人員只能通過人工的方法查找故障,處理故障的時間較長,嚴重地影響了行車�；诖�,本文提出了區(qū)間信號設備監(jiān)測系統(tǒng)方案。監(jiān)測系統(tǒng)由室外軌旁的監(jiān)測單元和室內(nèi)接口機組成。通過軌旁監(jiān)測單元監(jiān)測區(qū)間信號機點燈狀態(tài)、區(qū)間信號機電纜側(cè)和燈端側(cè)的電流電壓、區(qū)間軌道電路電纜側(cè)和軌道側(cè)的電流電壓和發(fā)碼狀態(tài),然后通過有線或者無線的方式將監(jiān)測的信息傳回室內(nèi)接口機,室內(nèi)接口機在室內(nèi)將監(jiān)測信息顯示出來,并把信息上傳給集中監(jiān)測系統(tǒng),集中監(jiān)測系統(tǒng)完成對區(qū)間信號設備監(jiān)測信息的檢查和報警分析。綜合考慮供電和通信線不需要重新布線,即直接使用既有的電纜的備用芯線作為數(shù)據(jù)傳輸和供電的通道,并且盡可能少用電纜芯線,減少現(xiàn)場的施工工作,因此,軌旁監(jiān)測單元和室內(nèi)接口機之間的通信方式為電力線載波通信。本文首先分析了電力線信道特性,通過國內(nèi)外載波芯片的對比,選擇了適合中國電力線信道的IT700載波芯片。然后詳細設計了區(qū)間監(jiān)測系統(tǒng)以及以IT700載波芯片為中心的電力線載波通信系統(tǒng),最后通過搭建電力線載波通信系統(tǒng)的硬件電路,對電力線載波通信的傳輸距離和誤碼率進行了分析,試驗表明以IT700載波芯片為中心設計的電力載波通信系統(tǒng)能保證區(qū)間信號監(jiān)測系統(tǒng)采集的數(shù)據(jù)進行遠距離可靠傳輸。
[Abstract]:After six times of raising the speed of the railway in our country, the speed of the train is faster and the interval between the trains is shorter and shorter, which increases the transportation capacity of the railway and plays a great role in promoting the development of the national economy of our country. The increase of train speed depends more and more on interval signal equipment. The normal operation of interval signal equipment becomes particularly important, but due to the influence of funds and technology when designing the system, the monitoring of outdoor equipment (such as signal generator and track circuit) is too little. According to statistics, most of the faults of signal equipment occur outside, but the centralized monitoring system is the signal collected indoors, which can not reflect the true operation state of the interval signal equipment outside. When the outdoor signal equipment breaks down, the electric operator can only find the fault by manual method, and the time to deal with the fault is longer, which seriously affects the driving. Based on this, this paper puts forward the scheme of interval signal equipment monitoring system. The monitoring system consists of an outdoor rail monitoring unit and an indoor interface machine. Through the track side monitoring unit to monitor the lighting state of the interval signal generator, the current voltage of the cable side and the lamp end side of the interval signal generator, the current voltage and the code state of the cable side and the track side of the interval track circuit, Then the monitoring information is transmitted back to the indoor interface machine by wired or wireless means. The indoor interface machine displays the monitoring information indoors and uploads the information to the centralized monitoring system. The centralized monitoring system completes the inspection and alarm analysis of the monitoring information of interval signal equipment. Considering that the power supply and communication lines do not need to be rewired, that is, the backup core wire of the existing cable is directly used as a channel for data transmission and power supply, and the cable core cable is used as little as possible to reduce the construction work in the field, therefore, The communication mode between the rail side monitoring unit and the indoor interface unit is power line carrier communication. Firstly, the characteristics of power line channel are analyzed, and the IT700 carrier chip suitable for Chinese power line channel is selected by comparing the domestic and foreign carrier chips. Then the interval monitoring system and the power line carrier communication system centered on IT700 carrier chip are designed in detail. Finally, the hardware circuit of the power line carrier communication system is built. The transmission distance and bit error rate of power line carrier communication are analyzed. The experimental results show that the power carrier communication system based on IT700 carrier chip can ensure the reliable transmission of the data collected by the interval signal monitoring system.
