本发明涉及自动测量技术领域，特别是涉及一种移动式站台限界测量仪和测量方法。The invention relates to the technical field of automatic measurement, in particular to a mobile station limit measurement instrument and a measurement method.
背景技术Background technique
随着近些年铁路的快速发展，列车运行速度越来越快，营运里程不断增加，因此对运输安全的要求也就越来越高。With the rapid development of railways in recent years, the trains are running faster and faster, and the operating mileage is increasing, so the requirements for transportation safety are getting higher and higher.
站台作为一个旅客上下车的场所，列车停稳后车辆与站台之间会有一个间隙，间隙过大时不能保证旅客安全、方便的进出车辆，间隙过小时则易造成列车剐蹭，因此站台边缘相对轨道的横向及垂向尺寸必须满足铁路站台限界的要求。The platform is a place for passengers to get on and off the train. After the train stops, there will be a gap between the vehicle and the platform. If the gap is too large, it cannot ensure the safety and convenience of passengers entering and exiting the vehicle. If the gap is too small, it is easy to cause the train to scratch. The lateral and vertical dimensions of the track must meet the requirements of railway platform boundaries.
随着线路的长期运营，受到多种因素影响，站台相对于线路的位置关系会发生变化，一旦站台某些部位侵入限界之内，有可能发生列车剐蹭事故，给铁路安全运营带来不良影响。按照站台限界管理要求，各房建部门要对管内站台限界实施动态管理，定期检测，全面、及时掌握站台限界的动态变化情况。目前铁路房建部门多采用手持工具进行测量，测量效率低，只能在个别断面进行定点测量，受人为因素的影响较大，检测精度低，耗费时间长、需要人力多。With the long-term operation of the line, affected by various factors, the positional relationship of the platform relative to the line will change. Once some parts of the platform intrude into the limit, train scratching accidents may occur, which will bring adverse effects on the safe operation of the railway. According to the requirements for the management of platform boundaries, each housing construction department shall implement dynamic management of the platform boundaries within the management, conduct regular inspections, and comprehensively and timely grasp the dynamic changes of the platform boundaries. At present, railway housing construction departments mostly use hand-held tools for measurement, and the measurement efficiency is low. Only fixed-point measurement can be carried out on individual sections. It is greatly affected by human factors, and the detection accuracy is low. It takes a long time and requires a lot of manpower.
因此需要研制一种移动式站台限界测量仪，对站台限界进行快速、连续检测。Therefore, it is necessary to develop a mobile platform limit measuring instrument, which can quickly and continuously detect the platform limit.

y1＝f-b；y1 =fb;
其中，m＝n/2；x1、y1分别为站台实测限界的横向、垂向距离。Among them, m=n/2; x1 and y1 are the lateral and vertical distances of the actual measured limit of the station, respectively.
本发明的有益效果：Beneficial effects of the present invention:
本发明实施例提供的移动式站台限界测量仪和测量方法，可实现对站台限界尺寸的移动连续测量，显著提高测量效率。The mobile station limit measuring instrument and the measuring method provided by the embodiments of the present invention can realize the moving and continuous measurement of the limit size of the station, and significantly improve the measurement efficiency.
具体体现在：Specifically reflected in:
(1)采用二维传感器快速获取站台断面数据，检测速度快，检测精度高。其断面采集间隔可小于10mm，相当于对站台的连续检测，因此在纵向上不会遗漏最不利断面；，在横断面上，同样为连续采集，无需人工定位最不利点，因此确保了测量的准确性和快速性。(1) Two-dimensional sensors are used to quickly obtain platform cross-section data, with fast detection speed and high detection accuracy. The section collection interval can be less than 10mm, which is equivalent to the continuous detection of the platform, so the most unfavorable section will not be missed in the longitudinal direction. Accuracy and speed.
(2)传感器定位装置通过在立柱上设置滑动定位组件，可以使传感器检测到不同高度站台的限界检测数据；通过设置立柱定位组件，保证了立柱与检测框架之间的重复定位的准确性，并且本实施例的立柱定位组件的具体结构，实现了立柱与检测框架的拆卸、拼装简单便捷，易于操作、节省时间，安全可靠，并且便于运输及存放的效果，并且保证立柱与检测框架的重复定位的准确性。(2) The sensor positioning device can enable the sensor to detect the limit detection data of platforms of different heights by setting the sliding positioning assembly on the column; by setting the column positioning assembly, the accuracy of repeated positioning between the column and the detection frame is ensured, and The specific structure of the column positioning assembly in this embodiment realizes the simple and convenient disassembly and assembly of the column and the detection frame, is easy to operate, saves time, is safe and reliable, and is convenient for transportation and storage, and ensures the repeated positioning of the column and the detection frame. accuracy.
(3)采用检测框架实现测量仪的平稳移动，在测量过程中操作人员只需平稳推动测量仪即可，大大降低了操作人员的工作复杂度。(3) The detection frame is used to realize the smooth movement of the measuring instrument. During the measurement process, the operator only needs to push the measuring instrument smoothly, which greatly reduces the work complexity of the operator.
