摘 要:自我國城市化建設以來,城市軌道交通發展較為迅速,我國地鐵行業對站臺門與列車門之間間隙安全防護也越來越重視,這使得對射式光柵檢測方式成為站臺門系統的標準配置,該方式能夠有效保證乘客在該間隙滯留的安全性。該檢測方法主要是以點對點的方式來實現,但在對其進行校準的過程中會出現一定的困難,且針對曲線站臺和間隙較大的站臺該方式存在檢測盲區。隨著我國科技技術的不斷發展,激光雷達檢測技術的穩定性與安全性大大提升,并且精度也有較大的提高,其在軌道交通站臺門安全防護方面有著廣闊的應用前景。

Abstract:Since China’s urbanization construction,urban rail transit has developed rapidly,and the subway industry in China has paid more and more attention to the gap safety protection between platform doors and train doors. This makes the shooting grating detection method become the standard configuration of platform door system,which can effectively ensure the safety of passengers staying in the gap. The detection method is mainly implemented by point-to-point method,but there will be some difficulties in its calibration process,and there is a blind area for the curve platform and the platform with large gap. With the continuous development of science and technology in our country,the stability and safety of lidar detection technology has been greatly improved,and the accuracy has also been greatly improved. It has broad application prospects in the safety protection of platform doors of rail transit.
Keywords:lidar detection technology;rail transit platform door;safety protection

自2017年以來,我國有34座城市開通了軌道交通線路,并在此基礎上全部實施運行,運行長度長達5000公里。我國在進行城市化建設過程中,為了緩解交通壓力,大力提倡軌道交通,并先后在多個城市開通了100多條運營線路,其中軌道交通在廣州、上海以及北京等城市應用較為廣泛,對緩解我國交通壓力發揮了重要的作用。此外,我國采用激光雷達檢測技術對軌道交通站臺門進行安全檢測,以此提升軌道交通運營線路的安全性。
