Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail.
Seeing Fig. 1, this utility model includes pallet 7, and pallet 7 is provided with optical distance measurement apparatus 1, radio transmitting device 2, data processing equipment 4 and data presentation device 5.Wherein, described optical distance measurement apparatus 1 includes that motor 3, radio transmitting device 2 and screw mandrel 6, motor 3 and radio transmitting device 2 are arranged on screw mandrel 6.
It is connected by radio transmitting device 2 between data processing equipment 4 with optical distance measurement apparatus 1, and wireless bidirectional communication can be carried out；It is attached by USB data line between data processing equipment 4 and data presentation device 5, carries out parallel port communication by taking p0 mouth, simple and convenient.
Radio transmitting device 2 includes laser generator and laser pickoff, utilizes the mode of optic communication to carry out wireless two-way transmission information between generating laser and laser pickoff.Generating laser and laser pickoff are arranged on screw mandrel 6.
Data processing equipment 4 is 51 single-chip microcomputers, and data presentation device 5 is LCD1602 display screen, and single-chip microcomputer is connected by parallel port with display screen.
Pallet 7 side is provided with touch switch and outlet.
Seeing Fig. 2, the principle of optical ranging system of the present utility model is as follows:
1. ranging unit
Use the range finding of isoceles triangle method.The property theorem of foundation triangle, it is known that its bottom side length and base angle size thereof, can calculate the height of this triangle.This method utilizes this principle.Minute surface is parallel with base, and on base, laser and base form an angle injection light, return to the moveable receptor on base, draw the distance of lasing light emitter and receptor, and then be computed drawing the distance of base and minute surface after direct reflection.
Laser is launched in screw mandrel one end, returns through direct reflection, constitutes isosceles triangle with base.Base angle determines that, base is obtained by following process: motor drives the laser pickoff slide block on screw mandrel to stop after the laser being transmitted back to being detected, single-chip microcomputer statistics motor pulses.The motor umber of pulse that turns around is fixed, and slide block displacement is fixed known.Then base is a length of: umber of pulse takes advantage of displacement number.
After drawing base, height can be obtained according to Vector triangle.Height seeks to the distance measured.
Theoretical Calculation
Hot spot is had, then in order to accurately, value-taking mean value process be used to draw base length after laser-bounce.
Turning around want n pulse if base is motor, m distance length walked by a circle, records and receives photoelectricity machine and walked N number of pulse, and light has disappeared M pulse, and incident angle is a, and measurement distance is h, then
2. communication part
Communication part uses class infrared-ray communication.Signal is transferred to a series of binary pulse string signal by transmitting terminal, is gone out by Laser emission.Receiving terminal transfers pulse signal to digital signal again, shows after process.Using laser pulse delivery data, equally, these data need integration to process, and the most still use 51 single-chip microcomputers to process, and display module uses LCD1602.This module can reality 16 letter or numbers, be entirely capable of realizing the function of display distance.
3. the movement of sensor
Use motor to drive screw mandrel, sensor is placed on screw mandrel slide block, calculate slide block sliding distance, and then calculate the distance requiring to survey.Screw mandrel rotation precision is high, motor pulse stabilization, can calculate slide block distance by the punching of control system rapid pulse, and easy to operate, precision is high.
4. data process and control part
It is core that these part data process, and realize calculating the distance of generating laser and sensor, and can the distance of sensor to minute surface be calculated, and control display shows, and transfers data to pulse signal and launch.To realize the most multi-functional simultaneously, take individual module the most complicated, therefore, be employed herein 51 single-chip microcomputers.
89C51 is that a kind of band 4K byte flashes the low-voltage of programmable and erasable, high-performance CMOS 8-bit microprocessor.It has the flicker able to programme of 4K byte, and 32 I/O draw mouth, it is possible to module each to its programming Control works, thus reaches to process requirement.
Work process of the present utility model is: after first turning on power supply, and generating laser starts carry pulse signal and launched by signal, is received the signal reflected by minute surface (determinand) afterwards by laser pickoff.The optical signal received is converted into the signal of telecommunication by receiving terminal, by drawing mouth, the signal of telecommunication is transferred to data processing equipment (single-chip microcomputer), data by the calculating process in above-mentioned principle, then are shown by data processing equipment by the signal that receives by the data line between display.
