本发明提供一种自动触发的磁浮轨道在线监测系统,包含:数据采集模块,其常态为休眠状态,用于采集磁浮列车经过监测点时的轨道状态参数;自动触发模块,其基于与监测点位置对应的至少一个定子段的电流信号生成第一、第二触发信号;所述第一触发信号用于在磁浮列车到达所述监测点前驱动数据采集模块开始工作,磁浮列车到达监测点时,数据采集模块已经进入稳定工作状态;所述第二触发信号用于在磁浮列车离开监测点后驱动数据采集模块进入休眠状态。本发明还提供一种自动触发的磁浮轨道在线监测方法。本发明能够在列车接近监测点时提前自动触发数据采集模块,保证数据采集模块采集有效数据并具有足够的响应时间,本发明的系统功耗低,使用寿命长。
The invention provides an automatically-triggered maglev track on-line monitoring system, which comprises a data acquisition module which is in a dormant state in a normal state and is used for acquiring track state parameters when a maglev train passes through a monitoring point; the automatic triggering module is used for generating a first triggering signal and a second triggering signal based on the current signal of at least one stator section corresponding to the position of the monitoring point; the first trigger signal is used for driving the data acquisition module to start working before the maglev train arrives at the monitoring point, and the data acquisition module enters a stable working state when the maglev train arrives at the monitoring point; the second trigger signal is used for driving the data acquisition module to enter a dormant state after the maglev train leaves the monitoring point. The invention further provides an on-line monitoring method for the automatically-triggered maglev track. The data acquisition module can be automatically triggered in advance when a train approaches a monitoring point, it is guaranteed that the data acquisition module acquires effective data and has enough response time, and the system is low in power consumption and long in service life.
