摘　　要：在站间隔的影响下地铁列车编队控制信号传输时延增大,为精准控制地铁列车的周期性间隔,提升列车编队的运行安全性,在宽带无线信息传输下设计地铁列车编队全周期运行控制系统。分别从车载设备、轨旁设备两个方面,完善运行控制系统的基础应用部件。联合宽带无线信息传输技术,对中控主机捕捉到的地铁列车信号进行编码。求解到站追踪间隔、出站追踪间隔与咽喉区长度,并以此为基础,实现地铁列车编队的全周期控制。联合优化后的应用部件,实现地铁列车编队全周期运行控制优化。实验结果表明:设计系统应用后,地铁列车的时间周期性间隔被控制在4~6 min,距离周期性间隔始终大于400 m,符合列车编队的安全运行标准。Under the influence of station spacing,the transmission delay of subway train formation control signal increases.In order to accurately control the periodic interval of subway trains and improve the operation safety of train formation,the sub⁃way train formation full⁃cycle operation control system is designed under the broadband wireless information transmission.The ba⁃sic application components of the operation control system is improved in the aspects of on⁃board equipment and trackside equip⁃ment.The subway train signal captured by the central control host is coded in combination with broadband wireless information transmission technology.The arrival tracking interval,departure tracking interval and station throat section length are solved.On this basis,the full⁃cycle control of metro train formation is realized.The full⁃cycle operation control optimization of subway train formation is realized in combination with the optimized application components.The experimental results show that the time peri⁃odic interval of metro trains is kept within 4~6 min,and the distance periodic interval is always greater than 400 m after the ap⁃plication of the designed system.Therefore,it conforms to the safe operation standard of train formation.
