2) train approaching protection
列车接近防护
3) train nearly alarm
列车接近报警
1.
Advanced a new programme about raising speed train nearly alarm system,on the basis of GSM-R,combined GPS and GIS,real-time monitoring position and speed of online running train,through computer network collected data to alarm server,transmitting alarm message from alarm server to alarm location of having alarm receiving equipment.
提出了一种新的提速列车接近报警方案,它以铁路移动通讯网络(GSM-R)为基础,结合全球定位系统(GPS)和铁路地理信息系统(GIS),实时监测在线运行列车的位置和速度,通过计算机网络汇总数据到报警服务器,由报警服务器向有报警接收设备的报警点发送报警信息。
4) Train approach annunciator
列车接近报警器
1.
Train approach annunciator is an important part in railway safety system and also a measure for ensuring the safety of railway working staff.
针对编组站的特殊环境,开发了一种基于高性能ARM单片机LPC2132、超声波换能器,以及RS-485串行通信总线的列车接近报警器。
6) approximating sequence
接近序列
1.
In this paper we proved there exists blocks of approximating sequence which is equivalent to the basis of 1_p (1≤<∞)and spreading model F of weakly stable Banach space E contains copy of lp or co and if l_p F then l_p
本文主要是证明了稳定Banach空间上任何接近序列有等价于1_p(1≤P<∞)单位向量基的块序列,及弱稳定Banach空间E的模F含1_p或C_o副本,并且当1_p(?)F时有1_p(?)E。
