摘        要
本論文是在現代軌道交通驅動飛速發展的條件下，對現代先進驅動技術的主流發展進行分析，根據社會科學技術的日益發展和現代化城市對大流量、快速、便捷、舒適等特點的軌道交通運輸方式的要求，討論城市軌道交通運輸建設在經濟建設中的未來展望，進而設計了直線電機驅動方式的地鐵模擬系統。
隨著城市現代化的發展，地鐵、輕軌等作為城市軌道交通的主要運輸方式，在改善城市交通擁擠情況、快速集散客流、提高人民生活水平、促進經濟發展中具有非常重要的作用。然而修建地鐵系統需要積聚大量資金，造價昂貴非常昂貴，在一定程度上延緩了軌道交通在我國的建設進程。采用直線電機驅動的地鐵或是高架軌道車輛，在改善曲線通過性能，提高穩定性的同時，降低了工程造價，非常適合各大城市中等運量交通發展的需要。直線電機地鐵的出現為城市軌道交通開辟了一條新的途徑，它是21世紀無人駕駛全自動地鐵系統的發展方向。直線電機地鐵技術比較成熟，具有造價低、振動小、噪聲低、爬坡能力強、牽引能力優越、通過曲線半徑小、能耗低、污染小、安全性能好等諸多優點，非常適合大中城市大中運量交通的要求。
本論文中主要說明射頻發射與接受裝置遙控直線電機驅動方式的地鐵模擬系統。對直線電機的歷史發展、工作原理、實踐應用以及射頻裝置控制電路所用的元器件使用原理、硬件電路和軟件控制說明等都做了詳細介紹。

Manufacture of Analogous Subway System in
Straight-lined Electric Motor Way
Abstract

This paper carries on the analysis to the modern advanced actuation technology mainstream development, under the rapid development of the modern track transportation. Nowadays the scientific technology id flourishing and modernized cities request the track transportation the characteristics of great current capacity, high speed, convenience, and comfort. According to this, the paper discussed the future of the track construction in the economy construction, and then designed the straight line motor-driven way subway analogous system.
 Along with the modernization of the city, the subway, the light axle as the main transporting mode, play an important role in improving the crowed transporting situation, fast gathering and scattering the passengers, raising the living standards of the people and promoting the economic development. However the construction of subway system needs massive funds for its high cost, delaying the process of the track construction of our country. While the straight line motor-driven subway or elevated track vehicles can improve the performance of passing the curve and raise the stability, meanwhile cut down the cost, satisfying the demand of the secondary quantity of transportation in big cities. And the appearance of the straight line motor-driven machine breaks a new way for the track transportation, making it the main direction of full-automatic subway system of unmanned operation. The technology of the straight line motor-driven subway has achieved a mature standard with low cost, small vibration, little noise, fine grade ability, advantageous tractive effort, well safety, small energy consumption and pollution 
The paper mainly explained the analogous straight line motor-subway system remotely controlled by the emitter and the receiver of the radio frequency. The historical development of the straight line electrical machine, its principle of work, and its practice application is introduced. Finally, the details used in the controlling circuit of the radio frequency installment are discussed, including their principle, application, as well as the illustration for use.
