First, the fixed block matching is relaxed. 一是对固定块(FB)的匹配算法进行了改进。
Firstly, on the base of brief analysis of the difference between moving block system and fixed block system, train operation adjustment model under moving block system is built up. 首先在对移动闭塞与固定闭塞差异进行简要分析的基础上,建立了移动闭塞条件下列车的运行调整模型。
On the basis of comparison among fixed block, quasi moving block and moving block, the problem of intervals control of train tracing has emphatically studied in the condition of moving block. 在比较固定闭塞、准移动闭塞和移动闭塞三种闭塞制式的基础上,着重对移动闭塞条件下列车追踪间隔控制问题进行了较深入的研究。
The moving block system has abandoned the block section of the fixed block system, which has greatly increased the intensity of the trains and improved the capacity of the lines. It makes the moving block system become the developmental trend of the train signal control system. 移动闭塞系统取消了固定闭塞系统的闭塞分区,这就极大地增加了线路上列车运行的密度,提高了轨道线路的通过能力,这就使移动闭塞成为列车信号控制系统的发展趋势。
By the structure of fixed block and fixed bush, not only die is steel saved, but also the ability of exhaust is improved, so the quality of the product is improved. 采用镶块、镶套结构,不仅节省模具钢,而且改善了模具的排气性,提高了产品的质量。
