According to the characteristic of train operation, the switch curve information based train positioning method is proposed in this paper, in which GPS receiver and inertial sensors are employed to obtain train`s operation state in switch, such as the train`s velocity, accelerator, and angular rate. The study calculates the difference of turning radius and rate of curvature and finds the running direction. Then the track occupied identification is realized accurately with the comparison to on-board track map database.
本文根据列车在铁路线路上运行的特点，提出了基于道岔曲线信息的列车定位方法，该方法利用GPS及惯性传感器辅助提取列车在道岔处的速度、加速度、角速度等运行特征，得到列车在道岔处的转弯半径、曲率变化及运行方向，并通过与车载地图数据库进行比较，实现准确的轨道占用识别及列车定位。
Hook empty-load, outward travel at low speed and extreme position limiting at max radius is 5m jib(outward R=50m, inward R=7.5m), enable one switch of the radius limiter(outward and inward travel is controlled by its parting limiter switch), when the trolleying to and extreme position limiting at max radius, enable another limiter switch(ourward and inward limiter switch), then trolley stop travel, when travel it again, the trolley just travel in the center of the jib frame.
4.4.3 幅度限位器调整(结构调整方法见外购件说明书) adjusting method for radiuslimiter(the procedures is shown as the outsourcing instructions)(1)吊钩空载，以低速档运行，向外行至距最大幅度处5 米时(向外时 R=50 米，向内时 R=7.5 米)，幅度限位器中的一个开关恰好动作(向外，向内分别由一个限位开关控制)，当小车行至最大幅度时，另外一个限位开关动作，小车停止运行，再启动时，小车只能往臂架中央运行。
By turning a switch, I established contact between the induction coil and the glass spiral, and the sea, lit up by our four lanterns, was illuminated for a radius of twenty-five meters.
我转动螺丝钉，使电磁铁跟曲玻璃管接通，灯亮了，海中有我们四盏探照灯的照射，周围二十五米内都明亮起来。
We know it will cause a vapor-liquid transition or switch between open and closed when change the radius of the nanotube or the channel-water interaction is triggered.
我们知道，改变纳米通道的半径或者纳米通道和水之间的相互作用，将会引起纳米通道内的汽液相变和开关状态的转换。
