Description
一種軌道測量系統及軌道測量方法,尤其是指一種利用光學感應器組成的系統,及利用光學感應器測量軌道不整形態的方法。 An orbit measurement system and orbit measurement method, in particular, a system composed of optical sensors and a method for measuring orbital irregularities using optical sensors.
在眾多的交通工具中,例如高鐵、火車、輕軌、捷運……等,都是使用到鐵軌作為移動媒介,而鐵軌本身的特殊性,無論是單軌制或是雙軌制,都只能讓特定的列車行駛,不會有其他交通工具與其搶道,因此,利用鐵軌作為移動媒介的交通工具大多為大眾交通運輸工具。換言之,這些列車只能行駛在特定的軌道上,一但因意外而駛離軌道,就無法正常地運行在一般路面,不但無法達成運輸的功能,還可能會因脫軌造成列車的翻覆,對乘客或是對其他用路人造成傷亡。 In many modes of transportation, such as high-speed rail, trains, light rail, MRT, etc., rails are used as mobile media, and the particularity of rails, whether it is single-rail system or dual-rail system, can only make certain When a train runs, there is no other means of transportation to grab the road, so most of the vehicles that use rails as mobile media are public transportation. In other words, these trains can only travel on a specific track. Once they leave the track due to an accident, they cannot run normally on the normal road. Not only can they not achieve the function of transportation, but also may cause the train to overturn due to derailment. Or cause casualties to other passers-by.
在眾多造成脫軌的意外中,其中一項為軌道不平整。造成軌道不平整的原因繁多且複雜。舉例而言,當地震發生時,可能會影響地面的平整性,進而扭曲鐵軌,使鐵軌的間距有所增減、兩條鐵軌間產生高低落差、鐵軌大幅地彎曲甚至斷裂,這些都有可能讓列車在行駛中脫軌,造成嚴重的安全問題;另外,列車行駛在鐵軌上時會對鐵軌施加力量,讓鐵軌些許形變,長時間反覆地行駛可能會造成金屬疲乏而累積鐵軌的形變量,使得列車在行駛過形變處會顛簸或搖晃,當鐵軌的形變量增加,顛簸或搖晃的程度隨之增加,雖不致影響行車安全,但會造成乘客的不適,以及物品的散落;而劇烈的溫度變化會使鐵軌的熱漲冷縮較為劇烈,同樣會影響乘車的舒適感。 Among the many accidents that caused derailment, one of them was uneven track. The causes of uneven track are numerous and complex. For example, when an earthquake occurs, it may affect the flatness of the ground, which will distort the rails, increase or decrease the distance between the rails, produce a high-low drop between the two rails, and greatly bend or even break the rails. The train derails while driving, causing serious safety problems. In addition, the train exerts force on the rail when it is running on the rail, causing the rail to deform slightly. Repeated driving for a long time may cause metal fatigue and accumulate the deformation of the rail, making the train It will bump or shake when driving through the deformation. When the deformation of the rail increases, the degree of bump or shaking will increase accordingly. Although it will not affect driving safety, it will cause discomfort to passengers and scattered items; and severe temperature changes will Making the railroad tracks heat up and down more drastically will also affect the ride comfort.
以往檢查鐵軌形變狀態的方法,一般為相關單位定期派遣人員行走在軌道上定點量測,惟這種方式費工費時,定點式的測量容易忽略掉某些形變量較大的軌道處,或是僅能得知某個定點的形變量,並無法知道一段長度的鐵軌是否以整體變形;定期式的檢查也不能及時發現且處理,無法有效率地解決此問題。 In the past, the method of checking the deformation status of the railroad track was usually to send personnel on the track to make fixed-point measurements on a regular basis. However, this method takes time and labor, and fixed-point measurement can easily ignore certain tracks with large deformation variables, or You can only know the deformation of a fixed point, and you cannot know whether a length of rail is deformed as a whole; regular inspections cannot be found and processed in time, and this problem cannot be solved efficiently.
