分析应答器传输模块(BTM)的动态特性,辨析与BTM动态特性相关的基本概念,包括静态作用距离、动态作用距离、最小允许作用距离、BTM的接收能力等,建立这些概念的数学表达式。给出了与BTM动态特性相关的关键参数计算方法以及BTM设备动态特性的测试方法。提出BTM在高速条件下的适用性评价步骤是:明确线路环境、机车环境和设备安装等外部约束条件,确定BTM设备的可用性需求,计算BTM的最小允许作用距离和最小允许作用时间、BTM的动态接收能力和动态处理能力等指标;对拟用BTM设备通过测试采集相关技术指标;将采集的指标与计算的指标进行比较,评价拟用BTM设备的适用性。通过此评价方法实现了对BTM动态特性及高速适用性的定量评价。
Analyze the dynamic characteristics of transponder transmission module (BTM), and analyze the basic concepts related to dynamic characteristics of BTM, including the static action distance, dynamic action distance, minimum allowable action distance, BTM receiving capability, and so on. The calculation methods of the key parameters related to the dynamic characteristics of the BTM and the testing methods of the dynamic characteristics of the BTM are given. It is proposed that the evaluation of the suitability of BTM under high-speed conditions is to clarify the external constraints such as line environment, locomotive environment and equipment installation, determine the availability requirements of BTM equipment, calculate the minimum allowable working distance and minimum allowable working time of BTM, the dynamic of BTM Receiving capability and dynamic processing capability; collect relevant technical indicators through testing using BTM equipment; compare the collected indicators with calculated indicators to evaluate the applicability of the proposed BTM equipment. The quantitative evaluation of the dynamic characteristics and high-speed applicability of the BTM is realized through this evaluation method.
