In conjunction with Fig. 1, a kind of lift rail perpendicularity detection system of the invention, including measuring mechanism, runing rest, serial ports Server 9 and control module;
Measuring mechanism includes the first ranging laser 1-1, the second ranging laser 1-2 and double-shaft tilt angle sensor 2, rotation Bracket includes supporting plate 3, shaft 4, shaft coupling 5, motor 6, cabinet 7 and motor driver 8;
The first ranging laser 1-1, the second ranging laser 1-2 and double-shaft tilt angle sensor 2 are arranged at bracket On plate 3, the motor is connected by shaft coupling 5, shaft 4 with supporting plate 3, and one end of motor driver 8 is connected to the motor, another End is connected by serial server 9 with control module, and control module controls supporting plate 3 and rotates;It is examined on measuring mechanism acquisition guide rail The position data of measuring point and the inclination data of measuring mechanism are sent to control module through serial server 9, and control module is according to connecing The position data and inclination data received determines slide rail verticality deviation.
The motor driver 8 and serial server 9 are arranged in cabinet, and supporting plate 3 is used as case lid, pass through shaft 4 It is movably arranged on cabinet.
The X-axis of the axis of the first ranging laser 1-1 and the second ranging laser 1-2 and obliquity sensor 2 is kept In parallel, two ranging lasers at the center of Y direction away from for 6-8mm, if spacing is greater than 10mm, it cannot be guaranteed that two rangings Laser all measures guide rail data;If spacing is too small, work region feature can not be preferably embodied with the plane that the data are fitted;
Or first ranging laser 1-1 and the second ranging laser 1-2 axis and obliquity sensor 2 Y-axis keep In parallel, two ranging lasers are at the center of X-direction away from for 6-8mm.
The present invention is further explained in the light of specific embodiments.
Embodiment
The rail survey unit structure of the present embodiment is as shown in Figure 1, the first ranging laser 1-1, the second ranging laser 1-2 and double-shaft tilt angle sensor 2 are located at 3 top of supporting plate, and the central axes of two ranging lasers and double-shaft tilt angle sensor 2 Y-axis it is parallel;Shaft coupling 5 and motor 6 are mounted in the shaft 4 of supporting plate 3, so that supporting plate 3 drives in above-mentioned component and motor It is rotated under the control of dynamic device 8;Serial server 9 and motor driver 8 are located inside cabinet 7.
The top view of above-mentioned component is as shown in Fig. 2, the two-laser spacing 8mm used in the present embodiment, range accuracy 0.1mm, the intelligent AIS-2000 double-shaft tilt angle sensor of obliquity sensor selection, 0.001 degree of precision.
The connection relationship of each element of measuring device and the flow direction of control information and data are as shown in figure 3, control module passes through Computer 10 realizes that 8 one end of serial server connects computer, and one end is separately connected ranging laser 1-1 and 1-2, twin shaft inclines Angle transducer 2 and motor driver 8, so that the data for acquiring sensor are sent to computer, or computer is generated Driving instruction is sent to motor driver 8.
Control module of the invention has the function of control and measure device and Measurement and Data Processing, control flow such as Fig. 4 It is shown comprising the steps of:
S1 opens serial ports, initializes the maximum height value H of guide rail to be measured and the space D of two ranging lasers;
S2, setting current cycle time i is 0, maximum cycle n=H/D;Set present level h0=0;
S3 reads the reading of obliquity sensor and 2 ranging lasers;
S4, according to next point height h=h to be measured0+ D calculates supporting plate and reaches the angle that the position need to rotate, and will Angle number is converted into the umber of pulse of control motor;
Control signal is issued motor driver, and drives supporting plate to go to specified angle under the effect of each component by S5;
S6 suspend mode 1 second, enables obliquity sensor measured value more stable;If i≤n, current cycle time i adds the value of 1, h to be assigned to Present level h0, then repeatedly step (3)-(6) operation;Otherwise, end loop executes S7;
S7, bracket sheet reset, measurement process terminate.
After measurement, original distance and inclination data are saved into array, are then converted under horizontal coordinates Coordinate data.If the inclination angle for measuring initial position is α0And β0, i.e. the posture of measuring device and the X-axis of horizontal coordinates and Y-axis Angle.In measurement process, the distance d that certain test point is measured by ranging laser 1-1 on guide rail, inclination alpha and β, then the point is converted Coordinate (x, y, z) under to horizontal coordinatesTAre as follows:
The test point of ranging laser 1-2 acquisition will be also moved under the coordinate system of laser 1-1 after above-mentioned transformation. After all detection point transformation, data processing is ready in coordinate value deposit array.
The data processing function of control module is divided into permutation detection and part detection both of which;According in national standard, About the measuring for verticality requirement of detection " the relative maximum deviation between the every 5m plumb line measured value of each column working face of guide rail ", permutation When detection, the perpendicularity deviation data at every 5 meters of intervals from guide rail bottom end to top, i.e. detection starting altitude h are exported1=0, detection Terminate height h2=H (the guide rail maximum height of user's input), intermediate detection height are followed successively by 5m, 10m ... ..., H/5m;Office Portion's detection then can be achieved to input the start-stop height h of guide rail section to be detected by user to the detection of any guide rail section interested1And h2, Intermediate detection height is followed successively by h1,……h1+h2/h1* 5, from calculate angle for, permutation detection be locally detect it is special Situation.
The basic principle of two kinds of detection patterns is similar with calculating process, as shown in figure 5, because measurement is only capable of obtaining guide rail surface Sparse test point can not obtain guide rail and arbitrarily detect total data in height, solution here are as follows: using to be detected Nearby four test points fit the section guide rail surface to height, then calculate the level at two guide levels and detection height The intersection point of face and vertical plane is to get perpendicularity deviation out.The specific detecting step of each guide rail section is as follows:
(1) data screening: from found out respectively in measurement data from, only height h and h+5 nearest four points, a~d and j ~m;
(2) plane fitting: utilizing least square method, is fitted respectively by point a~d and j~m and detects, stops near height Two plane P1And P2, that is, find out guide level equation A1x+B1y+C1z+D1=0 and A2x+B2y+C2z+D2=0 coefficient;
(3) intersection is determined: i.e. guide level P1And P2Respectively with detection height levels z1=h and z2The intersection l of=h+51 And l2
(4) perpendicularity deviation, i.e. straight line l are determined1And l2Intersect with plane x=5 (plane that 5mm is in horizontal plane) Distance between resulting two intersection point.
If guide rail top surface working face is parallel with yz plane, when guide rail only has the inclination for rotating around x axis and generating, current work Make the perpendicularity deviation in face close to 0, but side working face will test out perpendicularity deviation;Similarly, when guide rail is only rotated around y-axis And generate inclination when, top surface working face will detect perpendicularity deviation, and side then zero deflection;When guide rail has around x-axis and y-axis When rotation, top surface, side can detect deviation.
When the system works, stair shaft bottom or carriage top surface, two ranging laser face guide rails, it is ensured that laser point are placed in It can get on working face of guide rail.The runing rest of measuring device is under the control of control module, intermittent to rotate to a series of Angle position, measuring mechanism then above acquire the inclination data of guide rail range data and current location at various locations, and are sent to Computer, until completing the data acquisition of permutation guide rail.The process that data acquisition and perpendicularity deviation calculate is not necessarily to manual intervention, High degree of automation, speed are fast, and avoid the error introduced by manual operation.
