Abstract

The invention provides a full-airplane horizontal measurement method based on a work space measurement location system. The method comprises first determining the number of measured work spaces and laser scanning base stations according to appearance dimensions and positions of measuring points; then using a standard ruler to calibrate external parameters of the measured work spaces formed by all the laser scanning base stations, and building a work space measurement location system coordinate system; then unifying the work space measurement location system coordinate system and an airplane coordinate system; using vector rods of the work space measurement location system to respectively perform contact measurement on each measuring point; and finally enabling measured coordinate values of each measuring point to be led into a data processor of the work space measurement location system, and comparing the actually-measured coordinate values with a theoretical value so as to judge whether airplane deformation is within an allowed range. The full-airplane horizontal measurement method solves the problems that a traditional airplane horizontal measurement method is poor in measurement precision, large in workload and low in measurement efficiency and is subjected to influences of operator's proficiency and the like.

Description

The full machine level measurement method of aircraft based on work space measurement and positioning system
Technical field
The invention belongs to the on-the-spot large scale three-dimensional coordinate measurement of airplane industry technical field, particularly relate to the full machine level measurement method of a kind of high precision airplane digitalization based on work space measurement and positioning system.
Background technology
Work space measurement and positioning system (wMPS:Workspace Measurement Positioning System) is a kind of demand for industry spot global measuring and control and a kind of large scale network type measuring system of growing up it is advantageous that the networked high-precision automatic measuring that can realize the large scale volume coordinate.This system forms by a plurality of rotary laser emitters (cell site) measures network, employing positions single receiver based on the space angle intersection method for automatic measurement of optoelectronic scanning, the cell site outwards launches the light signal with angle information when work, for the photelectric receiver in the measurement space provides positioning service.When work in the cell site, its rotation platform at the uniform velocity rotates and outwards launches the planar laser that two bundles together rotate with turntable around stationary shaft, and the laser instrument on the pedestal sends the omnidirectional light pulse as the sync mark of single-revolution rotation starting point when rotation platform goes to a precalculated position simultaneously.Receiver receives sync mark light signal and plane of scanning motion light signal and by internal timer record time value this moment, and then calculates the angle that the cell site turns over.After oneself knows cell site's azimuth information, only need to obtain the angle measurement of two above base stations, the method that just can use angle crosses calculates the receiver accurate coordinates of this moment.
Aircraft take a flight test, fight and train etc. in the flight course, usually can be subject to larger mistake load, this can cause the permanent strain of airframe, wing and empennage.But can not in time find and take corresponding measure if deflection is excessive, can directly have influence on the flying quality of aircraft, even jeopardize flight safety.Airplane horizontal survey is to utilize the horizontal survey point on fuselage, wing and the empennage to come the relative position of aircraft all parts and the in use inspection of deformation thereof are confirmed.Therefore, for guaranteeing good flying quality and higher flight safety, the horizontal survey of aircraft has very important meaning.
The method of traditional survey aircraft fuselage, wing and empennage distortion is as main aircraft to be carried out horizontal survey take the traditional optical surveying instrument, and the survey instrument that uses is optical theodolite and steel tape etc.This traditional measuring method measuring accuracy is poor, workload large, it is low and be subject to easily the impact of operating personnel's proficiency to measure efficient, and therefore, the measuring method that designs a kind of high-accuracy high-efficiency rate becomes airplane horizontal survey work problem demanding prompt solution.
Summary of the invention
The purpose of this invention is to provide and the present invention proposes the full machine level measurement method of a kind of aircraft based on work space measurement and positioning system, solve that the measuring accuracy that exists in the conventional airplane level measurement method is poor, workload large, to measure efficient low and be subject to easily the problems such as impact of operating personnel's proficiency.
Technical scheme of the present invention: the full machine level measurement method of aircraft based on work space measurement and positioning system comprises the steps:
(1) according to physical dimension and the location positioning surveying work space of measurement point and the quantity of laser scanning base station of tested aircraft, so that each measurement point is positioned at the best effort distance of Laser emission base station, and the laser intersection angle that send two Laser emission base stations is 60 °-90 °, and guarantee that measurement point without blocking, has preferably measurability;
(2) use station meter that the demarcation of external parameter is carried out in the surveying work space that all laser scanning base stations consist of, set up work space measurement and positioning system coordinate system;
(3) choose reference point and set up aircraft axes at airframe, so that the coordinate figure of reference point in aircraft axes is definite value; Then the coordinate of datum mark under work space measuring system coordinate system, work space measuring system coordinate system and aircraft axes are unified, thereby so that the coordinate figure that records under work space measuring system coordinate system is scaled the coordinate figure in aircraft axes;
(4) use the vector rod of work space measurement and positioning system respectively each measurement point to be carried out contact type measurement, record successively the coordinate figure of each measurement point on fuselage, the wing; For measurement point higher on the aircraft tail, cooperate the vector rod to measure by extension rod;
The coordinate figure of each measurement point that (5) will record imports in the data processor of work space measurement and positioning system, draw the Measured Coordinates value of each measurement point in aircraft axes, theoretical value compares in Measured Coordinates value in the aircraft axes and the aircraft axes, and then judges that aircraft distortion is whether in permissible range.
Beneficial effect of the present invention: the present invention adopts work space measurement and positioning system to finish the full machine horizontal survey task of aircraft, and method is simple to operate, and is lower to the requirement of staff's number and technical merit; Measuring accuracy is high, and measuring speed is fast, has reduced greatly the surveying work amount; Measurement result directly imports data processor and theoretical value compares, and comparative result is convenient to analysis and adjustment is carried out in the distortion at each position of aircraft with form output display intuitively.
