技术领域technical field
本发明属于仪器设备检测校准技术领域,特别涉及一种室内图像式垂准仪校准装置。The invention belongs to the technical field of instrument detection and calibration, in particular to an indoor image-type vertical collimator calibration device.
背景技术Background technique
垂准仪是以重力线为基准,利用与视准轴重合的可见光或激光产生一条向上和向下的铅垂线,用于测量相对铅垂线的微小水平偏差以及进行铅垂线的定位、物体垂直轮廓测量的计量仪器。常用的垂准仪有光学垂准仪、带激光器的光学垂准仪、激光垂准仪和激光自动垂准仪。它广泛用于高层建筑、高塔、烟囱的施工,发射阱、架及大型柱形机械设备的安装,电梯检测,大坝的水平位移测量,工程监理和变形观测等场合,为国家经济建设和军事发展提供有力保障。近年来,随着国民经济的快速发展,对垂准仪的需求越来越大,对垂准仪的准确度要求也越来越高,出厂和使用过程中的垂准仪都需要校准和调校,否则使用失准或已经损坏的垂准仪将会使建筑工程产生巨大的安全隐患,为此 2002 年国家质量监督检验检疫总局出台了JJF1081-2002《垂准仪校准规范》,通过校准保证垂准仪的计量性能准确度,从而给施工建设提供一个可靠的标准。The vertical collimator is based on the gravity line, and uses the visible light or laser coincident with the collimation axis to generate an upward and downward plumb line, which is used to measure the slight horizontal deviation relative to the plumb line and to position the plumb line, Metrology instrument for measuring the vertical profile of an object. Commonly used collimators include optical collimators, optical collimators with lasers, laser collimators and laser automatic collimators. It is widely used in the construction of high-rise buildings, towers and chimneys, the installation of launch traps, racks and large-scale cylindrical mechanical equipment, elevator detection, horizontal displacement measurement of dams, engineering supervision and deformation observation and other occasions. Military development provides a strong guarantee. In recent years, with the rapid development of the national economy, the demand for collimators is increasing, and the accuracy requirements for collimators are also getting higher and higher. The collimators need to be calibrated and adjusted during delivery and use Otherwise, the use of an inaccurate or damaged collimator will cause huge safety hazards in construction projects. For this reason, in 2002, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China issued JJF1081-2002 "Vertical Calibration Specification", which is guaranteed by calibration. The measurement performance accuracy of the vertical collimator provides a reliable standard for construction.
JJF1081-2002《垂准仪校准规范》规定了竖轴与望远镜视准轴的同轴度、一测回垂准测量偏差等参数技术要求,并对垂准仪技术指标的校准方法进行了说明,指出光学垂准仪和带激光器的光学垂准仪的一测回垂准测量标准偏差按室内方法校准,可以采用类似经纬仪水准仪检定装置对其进行校准,激光垂准仪的一测回垂准测量标准偏差按室外方法校准,但采用室外方法对激光垂准仪进行校准时存在以下问题:(1)激光垂准仪的校准是在室外大于40 m 的场地上进行的,气流扰动、空气污染、机械振动等环境因素都对激光的稳定性有较大影响;(2)室外工况环境也对测量人员精确而稳定地布置和架设测量设备提出了较高的要求,且校准时需要两个以上的人员配合完成;(3)校准数据需要校准人员在分度值较大的直角坐标板上进行人工估读。JJF1081-2002 "Calibration Specification for Vertical Collimator" stipulates the technical requirements for parameters such as the coaxiality of the vertical axis and the collimation axis of the telescope, the deviation of the vertical alignment measurement for one measurement round, and explains the calibration method of the technical indicators of the vertical collimator. It is pointed out that the standard deviation of the one-round vertical alignment measurement of the optical vertical collimator and the optical vertical collimator with laser is calibrated according to the indoor method, and can be calibrated by a similar theodolite level verification device. The one-round vertical alignment measurement of the laser vertical collimator The standard deviation is calibrated according to the outdoor method, but the following problems exist when using the outdoor method to calibrate the laser vertical collimator: (1) The calibration of the laser vertical collimator is carried out on an outdoor site greater than 40 m, and there are air disturbances, air pollution, Environmental factors such as mechanical vibration have a great impact on the stability of the laser; (2) The outdoor working environment also puts forward higher requirements for the measurement personnel to accurately and stably arrange and erect the measurement equipment, and more than two calibrations are required. (3) The calibration data needs to be manually estimated and read by the calibration personnel on the Cartesian coordinate board with a larger index value.
