The invention, which relates to the maglev train control technology, discloses a speed measuring and positioning method and system for a maglev train and the maglev train, and. According to the speedmeasuring and positioning method, on-board equipment acquires speed and position information of a first speed measurement system in a normal case; a ground traction control system acquires speed and position information of a second speed measurement system; the speed and position information of the first speed measurement system is directly transmitted to the on-board equipment and the speed and position information of the second speed measurement system is directly transmitted to the ground traction control system at the same time. Because of no transmission delay, the on-board equipment andthe ground traction control system synchronously receive the speed and position information of the train, so that the communication period is greatly shortened, the transmission delay of the speed andposition information is greatly shortened, and the reliability of the system is improved. The first speed measurement system and the second speed measurement system can operate independently and information interaction can be realized through the communication bus, so that cooperative work of the two speed measurement systems is realized and control over head-to-tail switching of trains is achieved.
本发明公开了一种磁浮列车的测速定位方法、系统以及磁浮列车,涉及磁浮列车控制技术。所述测速定位方法,在正常的情况下,车上设备采信第一测速系统的速度和位置信息,地面牵引控制系统采信第二测速系统的速度和位置信息,由于第一测速系统的速度和位置信息直接传输给车上设备的同时,第二测速系统的速度和位置信息直接传输给地面牵引控制系统,无传输延时,使车上设备和地面牵引控制系统同步接收到列车的速度和位置信息,大大降低了通讯周期和速度与位置信息的传输延迟,提高了系统的可靠性;第一测速系统和第二测速系统既能够独立运行,又能通过通信总线实现信息交互,从而实现了两种测速系统的协同工作,以及列车首尾切换的控制。
