摘　　要：在深圳地铁3号线塘坑站两端的地下长大区间分散布置了众多的区间射流风机。介绍了风机的三级控制,从影响通信的不同因素,如通信距离、通信效果、工程投资等对实现BAS(环境与设备监控系统)的通信方案进行分析和方案比选,提出了适合区间现状和设备特点的多模光纤通信技术,实现了风机监控信号与BAS的可靠通信,取得了良好的实用效果。A lot of powerful jet fans are scattered on both sides of the long interval tunnel at Tangkeng Station of Shenzhen metro Line 3. The three-level control of the jet fans is introduced, the influential factors over BAS communications are analyzed and different schemes compared. Finally the multi-mode optical fiber communication technology is proposed, which is suitable for the long interval tunnel and could achieve reliable monitoring signal transmission between the jet fans and BAS. The practical effect of this design is also verified.
