    摘要： A motion control system for an independent cart system provides for an improved system for controlling operation of movers in areas of high traffic. A controller monitors operation of the movers to detect heavy traffic. In heavy traffic, the controller may bring a mover to a stop to avoid collisions. Once a mover is stopped, the segment controller will look at the present location of the mover and determine whether it is at the desired position set in the motion command. If the mover is not at the desired position, the stop was a result of heavy traffic. After detecting heavy traffic, the controller commands the mover to resume travel using a modified motion command. The modified motion command will command the first mover to its desired position but will command the move at a reduced rate or using a reduced response in the controller.

    摘要： A system for determining a stationary state of a rail vehicle on a track includes a first radar mounted at an end of the rail vehicle and a second radar mounted at another end of the rail vehicle. A speed sensor is mounted on the rail vehicle. A series of fixed reflective track features are found along the track. A processing unit, communicably connected with the speed sensor, the first radar and the second radar receives data from the first radar and the second radar corresponding to the distance to the fixed reflective track features and determines the stationary state or low-speed condition of the rail vehicle and checks the state or condition by comparing it with an output of the speed sensor.

    摘要： A method and device for dynamically adjusting train interval based on wide-area interlocking control, and a computer-readable storage medium. The method includes: (1) dynamically managing trains; (2) identifying a following relationship; if there is a following relationship, performing step (3), otherwise, controlling the train using existing control technology; (3) identifying weather; if the thunderstorm weather occurs, performing step (4); otherwise, adjusting the train interval by existing control technology; (4) acquiring operation states of a wireless communication system, traction power grid, traction drive system and train control system in real time; if the operation conditions are normal, performing step (5), otherwise, performing step (6); (5) independently analyzing the safety of actual following distance by the preceding and following trains in real time; performing interlocking control according to analysis results; and (6) activating a fail-safe interlocking control module to ensure dynamic and safe control of the train interval.
