Pavement settlement online monitoring method and system
The invention relates to a pavement settlement online monitoring method and system. The method comprises the steps arranging a monitoring standard template at a road surface monitoring point, and arranging a template standard line on the monitoring standard template; emitting laser to the template standard line through a laser emitting device; vertically aligning the laser emitting device with theplane where the monitoring standard template is located to obtain a light spot; determining a distance between the light spot and the template standard line, and setting the distance as a first distance; after the duration is set, determining a distance between the light spot and the template standard line, and setting the distance as a second distance; if the first distance is the same as the second distance, determining that the pavement settlement does not occur; if the first distance is different from the second distance, determining that pavement settlement occurs; acquiring a laser emission angle of an inclination angle measurement module; and determining a pavement settlement value of the pavement monitoring point according to the first distance, the second distance and the laser emission angle. Therefore, problems that in an existing measuring mode, the safety of measuring personnel cannot be guaranteed, the measuring cost is high, and pavement settlement data cannot be monitored on line in real time are solved.
本发明涉及一种路面沉降在线监测方法及系统。该方法包括：将监测标准模板设置在路面监测点，监测标准模板上设置模板标准线；通过激光发射装置发射激光至模板标准线；将激光发射装置垂直对准监测标准模板所在的平面，得到光斑；确定光斑和模板标准线之间的距离，设为第一距离；设定时长后，确定光斑和模板标准线之间的距离，设为第二距离；若第一距离和第二距离相同，则未发生路面沉降；若第一距离和第二距离不同，则发生路面沉降；获取倾角测量模块的激光发射角度；根据第一距离、第二距离和激光发射角度，确定路面监测点的路面沉降值。本发明解决了现有的测量方式中测量人员安全无法保证，测量成本高且路面沉降数据无法实时在线监测的问题。
