  1. The article consists of three parts mainly : the first part has described the method of detecting the faint signal, mainly include : detection technique of faint signal, principle of the optical fibre sensor, the little lose effects when optic fibre little curved, and the research of the stress sensor of optical fibre. the second part emphasizes on the design of the intelligent photoelectricity system, mainly tells the design of the circuit to process the faint photoelectricity signal, details the software and hardware design of intelligent photoelectricity system made of single chip microcontroller, led, man - machine interface, communication interface, etc. the third part is the network communication of the detection system, details the technology of single chip microcontroller how to group the network, and the communication between single the chip microcontroller system and the modem, and how to realize the data between the field and computer central exchanged through the existing public phone network

    文章主要分為三部分:第一部分論述了微小信號的檢測方法,主要包括微小信號的檢測技術、光纖傳感器的原理、光纖微彎損耗效應及光纖應力傳感器的研製;第二部分重點講述了智能光電檢測系統的研製,主要講述了微弱光電信號調理電路的設計及由前(后)向通道、單片機、 led 、人機介面、通信介面等組成的智能光電系統的軟硬體的具體設計;第三部分為檢測系統的網路通信部分,具體闡述了單片機系統間的組網技術、單片機和modem之間的通信及通過現有的公用電話網路實現遠程監控的技術,實現現場檢測系統與橋梁測控中心的數據交換。
  2. According to the test conditions, the double polarity inputting mode is adopted in the circuit of voltage - frequency converting part ; storage batteries are used in the optical emission part of optical fibre isolating and transmitting device, that can guarantee isolation between the main circuit and the testing system ; the 89c51 singlechip is used in the singlechip testing - controlling unit, the peripheral circuits are extended, data are transmitted through the serial port in this part ; the p opular software delphi5. 0 is used in the pc part, the communication between singlechip and pc by serial port, plotting of current wave, regulation of data ; the optical - electrical isolating and triggering are used in the controlling part, this can guarantee the veracity and reliability of breakers triggered, this triggering mode is also used in the triggering of the main closing breaker, the tested breaker and the assistant breaker, the triggering signals are sent out by a singlechip

    壓頻轉換部分電路中根據實際情況採用了雙極性輸入方式;光纖隔離傳輸裝置的光發射部分電源採用了蓄電池供電,確保了主迴路與測試迴路的完全隔離;單片機測控部分採用了89c51單片機,擴充了外圍電路,通過串口向pc機傳送數據; pc機與單片機之間的串口通訊、波形繪制、數據管理等都採用了軟體delphi5 . 0編寫。該測試系統中預留了輸出口,可以對合成迴路中的主合閘開關、被試開關、輔助開關進行觸發,信號由單片機發出,控制部分採用了光電耦合隔離觸發的方法。軟體設計主要集中在對電流信號的數據採集、數據處理、數據傳送、人機界面、波形繪制和數據管理,軟體部分又可分為單片機和pc機程序設計兩大部分。
  3. On physical layer, it consists of a variety of ne ( network elements ) with different functions connected by optical fibre cables. compared with pdh, sdh is more widely used in fibre optical communication system these days. the reasons of the wide applicability of sdh are : first, it provides worldwide standards for electrical interface and optical interface, which can promote multi - vendor interoperability ; second, it has the feature of synchronous multiplexing and flexible mapping mechanism, so it can use stm - 1 signal to bundle atm cells, fddi signals as well as pdh signals

    Sdh之所以具有強大的生命力和廣泛的適應性,主要有兩個原因:提供統一標準的光介面和電介面,使不同廠家設備實現橫向兼容;採用同步復用方式和靈活的映射結構,以基本傳輸模塊stm - 1為橋梁,與原有的pdh信號實現縱向的前向兼容,與atm 、 fddi等數字體制實現後向兼容。
