Distance between two radio access points can reach about 300 to 600m。 Bombardier CITYFLO 650?s data transmission system adopts two types of antenna depending on different environment. Each type of antenna has its own advantages. Therefore, the signaling system can be able to guarantee maximum radio coverage and minimum munication loss at any case. 對(duì)于隧道里的運(yùn)行, CITYFLO 650 系統(tǒng)采用沿軌道分布的 Radiax漏纜天線系統(tǒng),對(duì)于地面或高架區(qū)域,信號(hào)系統(tǒng)采用可視天線( LoS)系統(tǒng)。 Here, the main concern is, the mechanism to produce “black hole” is very plicated. This depends on feature of tunnel, condition of wall, location of ventilation shaft and station platform, etc. Therefore, during design stage, it is little possible to predict “black hole” effect. 如果在發(fā)射器和接收列車(chē)之間存在另一列列車(chē), 也可能會(huì)阻斷該信 Technical Specification of Shenzhen Line 2 22 號(hào),因此,在考慮多路徑效應(yīng)時(shí),還得考慮動(dòng)態(tài)因素。這樣,可以更進(jìn)一步減小多路徑信號(hào),并且使得任何他人監(jiān)聽(tīng)或干擾無(wú)線信號(hào)的企圖變得困難。因此, Bombardier 在沒(méi)有隧道墻壁或屋頂?shù)拈_(kāi)放區(qū)域采用 LoS 天線的無(wú)線通信系統(tǒng)。 For LoS method, it is required to mount positioning antenna on the Technical Specification of Shenzhen Line 2 25 train and wayside. There are two advantages of using positioning antenna: increasing benefit and inhibition of front and back parison. Increase beneft can obvioulsy increase extra volume of link route. And inhibition of front and back parison can reduce inteference source being far away from injection hole of antenna (like the inteference from multiroute effect). 無(wú)線傳輸丟失 Loss of Radio Communication CITYFLO 650 系統(tǒng)的設(shè)計(jì)理念允許無(wú)線通訊有瞬時(shí)的丟失,這不會(huì)影響系統(tǒng)的安全性,也不需要為確保系統(tǒng)安全而采取緊急制動(dòng)措施。 If transicient radio munication loses due to interference or temporary effect, a train loses one or two radio munication Technical Specification of Shenzhen Line 2 26 messages. The train will continue to operate at allowable speed till the last known MAL point. In addition, as soon as radio municatin reestablishes, the train will get an updated MAL message, so as to continue its operation w
