摘要
随着我国经济的不断发展,人们对快速出行的需求日益增大。为缩短行车间隔时间,以移动闭塞为基础,提出了快慢车越行模式,并设计了基于移动闭塞的越行系统。该系统采用开源电子原型平台作为控制中心,利用测距芯片实时检测两车之间距离,并实现了车-车通信;测距芯片传回的信息交由基站内的核心控制系统,系统再对数据进行处理分析,并判断两车距离是否小于预先设定的安全防护距离;控制中心针对不同情况对快慢车的电机驱动模块发送相应命令,实现两车安全防护下的越行功能;在越行站内设置越行警示灯,给相关工作人员及乘客提供预警,排除因进站信号机亮红灯锁闭使快车不能实现越行的隐患。利用该系统,可缩短乘客等待时间、增大行车密度、减少部分轨旁设备的建设。
With the continuous development of China′s economy,people′s demand for fast travel is increasing.In order to shorten the time between trains,based on moving block,the fast and slow vehicle overrunning mode is proposed,and the overrunning system based on moving block is designed.The open source electronic prototype platform is used as the control center,and the distance between the two vehicles is detected by the ranging chip in real time,and the vehicle-to-vehicle communication is realized.The information returned by the ranging chip is sent to the core control system in the base station,and the system processes and analyzes the data,and determines whether the distance between the two vehicles is less than the pre-set safety protection distance.According to different conditions,the control center sends corresponding commands to the motor drive module of the fast and slow vehicles to realize the function of overrunning under the safety protection of the two vehicles;The overpass warning light is set in the overpass station to provide early warning to relevant staff and passengers,and eliminate the hidden danger that the express can not realize the overpass due to the red light and lock of the inbound signal.Using this system,the waiting time of passengers can be shortened,the traffic density can be increased,and the construction of some trackside equipment can be reduced.
