“神州”号内燃动车组监控装置制动计算参数及三显示区段监控模式的选择

针对“神州”号内燃动车组最高运行速度180km/h,动车组监控模式中制动模式曲线计算参数的不同和北京一天津间行车设备采用三显示交流计数自动闭塞,进行了制动计算参数的选择和三种控制模式的比较,并进行了试验验证。试验表明,“神州”号内燃机动车组制动模式曲线设定的计算参数符合实际;北京一天津间最好采用四显示自动闭塞;为了适应目前的三显示自动闭塞,监控模式以连接控制为宜,同时按闭塞分区长度来限速。

Selection of braking calculation parameters for "SHEN ZHOU" HAO DMU monitoring device and monitor modes for three-aspect section

SHEN ZHOU" HAO DMU has a max running speed of 180 km/h, of which the calculation parameters of the braking mode curve in the monitor ing mode are different. Between sections of Beijing to Tianjin its running equip ment are of automatic blocking with three-aspect & AC counting. Braking calcula tion parameters are selected and three control modes are compared. Test shows th at the calculation parameters set for the braking mode curve of the DMU are prac tical. It is also shown that between sections of Beijing to Tianjin it's better to have four-aspect automatic blocking for currently three-aspect automatic bl ocking, and that the monitor mode is better to be continuous control with the sp eeds limited by lengths of blocking sections.
