Device and method for monitoring irregular settlement of two sides of subway track
The invention relates to a device and a method for monitoring irregular settlement of two sides of a subway track, and belongs to the field of track traffic transportation. The irregular settlement monitoring device comprises a sensor module, a data acquisition module, a data processing module and a state evaluation module. The irregular settlement monitoring method comprises the following steps: continuously measuring and calculating acceleration data of each carriage by a subway train fleet provided with a monitoring device; judging whether the left and right acceleration vector included angle of the subway train carriage is greater than a first threshold value; judging whether the angle is larger than the first threshold value or not when other carriages of the subway train pass through the position; and sequentially analyzing whether the irregular settlement phenomenon of the two sides of the suspected rail occurs on all the subway trains passing through the suspected settlement point or not in the same evaluation grade time period or other evaluation grade time periods. According to the invention, the automation of irregular settlement monitoring of the two sides of the subway track is realized, and the efficiency and the automation degree of existing regular manual inspection can be improved and perfected.
本发明涉及一种地铁轨道两侧不规则沉降监测装置和方法，属于轨道交通运输领域。所述不规则沉降监测装置，包括传感器模块、数据采集模块、数据处理模块和状态评估模块。所述不规则沉降监测方法，包括：安装有监测装置的地铁列车车队连续测量并计算每节车厢的加速度数据；判断地铁列车车厢左、右两侧加速度矢量夹角是否大于第一阈值；判断所述地铁列车其他车厢通过此位置时的是否大于所述第一阈值；依次分析在同一及其他评价等级时间段内，所有通过所述疑似沉降点的地铁列车是否出现疑似轨道两侧不规则沉降现象。本发明实现了对地铁轨道两侧不规则沉降监测的自动化，能提高和完善现有定期人工检查的效率和自动化程度。
