| 摘 要： | 分析列车超速防护系统的制动精度和它的安全防护距离的设计问题。当列车在超速防护系统的控制下实施制动时，无论是常用制动，还是紧急制动，它的制动精度受诸多因素的影响，如制动初速、制动方式、控制方式、制动系统的离散性、超速防护系统本身的控制精度、不同的天气对轮轨粘着程度的影响等等。只有对这些因素进行分析后，才能合理地确定安全防护距离，使列车超速防护系统能确保行车安全，提高运输效率，又能不干扰司机对列车的正常驾驶。

| Abstract: | The paper analyzes the issues on the braking accuracy and its safety protection distance designed for automatic train overspeed protection system. When a train is actuated to brake by automatic train control system, no matter it is service braking or emergency braking, its braking accuracy is affected by many factors, such as the initial speed of braking train, the way control,the braking system dispersion and the control accuracy of train overspeed protection system, the influence on wheel-rail adhesion under different whether and so on. As long as the above factors are analyzed the safety protection distance could be decided correctly to make automatic train overspeed protection system ensuring operation safety and raise transportation efficiency while normal operation is not disturbed. |
