Abstract
The invention relates to a laser range finder which can measure area automatically and the device comprises a display module, a singlechip, a laser ranging module, a stepper motor and an input keyboard. The rotating angle of the stepper motor per time can be controlled by the keyboard input value inputted to the input keyboard and the laser ranging module measures distance under the control of the stepper motor while each measured result is stored in a RAM, at last, the required area can be acquired by overlapping the results. Compared with the prior art, the invention has the characteristics of simple and convenient operation, rapid speed, low requirement for measuring environment, high measuring accuracy, etc.
Description
Technical field
The invention belongs to the automatic measuring instrument field, relate to a kind of laser range finder of automatically measuring area.
Background technology
Along with the continuous development of science and technology with to the continuous maturation of laser research, laser ranging more and more widely be applied to Defence business and industrial.
Traditional laser range finder can only be simple measuring distance, the perhaps set area of graph of simple application formula computation rule.Get artificial repetitive operation when wanting the calculation of complex area, the computing that superposes, cumbersome, make mistakes easily; And people's sight line has error, the deviation effects result of the angle of measuring distance, and error is very big in the time of long-pending over there cutting apart; Some measured zone is complete irregular figure, does not have unified formula to seek, and the process of cutting apart stack is very loaded down with trivial details, and makes mistakes especially easily.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of sharp simple to operate for the weak point that overcomes above-mentioned prior art existence, and convenient, speed is fast, and is low to the measurement environment conditional request, the laser range finder of the automatically measuring area that measuring accuracy is high.
Purpose of the present invention can be achieved through the following technical solutions: 1. the laser range finder of an automatically measuring area, it is characterized in that, this device comprises display module, single-chip microcomputer, laser ranging module, stepper motor, input keyboard, by the each angle of rotating of the keyboard input-value control step motor of input keyboard, the laser ranging module is carried out the measurement of distance under Stepping Motor Control, each result who measures is saved among the RAM, and being superimposed at last obtains trying to achieve area.
Described laser ranging module comprises Laser emission, laser pick-off, submodules such as control.
The number of times that described keyboard input-value is represented to rotate a circle stepper motor laser range finder measured, the rotation of Single-chip Controlling stepper motor.
Described laser ranging module is carried out the measurement of distance under Stepping Motor Control.
The calculating of described area replaces the area of irregular figure with leg-of-mutton area.
Compared with prior art, the present invention is directed to existing laser range finder application limit, and the inconvenience on using, this laser range finder just can be finished the measurement of this region area automatically as long as rotating a circle with fixed point.This fixed point can freely be provided with, as long as all right in this surface area, does not have the error that vision is selected, and is easy to use, remedied the deficiency of traditional product.Except being used for traditional range observation, can also be used for finishing automatically the measurement of specific region area.Have the following advantages:
1) this laser range finder can also be finished the measurement of area automatically except finishing the measurement of distance
2) effective especially to the measurement in areas with irregular and space
3) any can both finish the measurement of area arbitrarily in the specific region, and is easy to use, and measurement environment is not had harsh requirement.
4) because the value of N can freely be set, and N is big more, the area of measurement is accurate more, can satisfy high-precision requirement;
5) because the N value is freely to set, the user can adjust precision as required, can better meet user's requirement.
Description of drawings
Fig. 1 is a system chart of the present invention;
Fig. 2 is a control flow chart of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1, a kind of laser range finder of automatically measuring area is mainly by display module, single-chip microcomputer, laser ranging module (comprising Laser emission, laser pick-off, submodules such as control), stepper motor, compositions such as input keyboard.
The angle of the each rotation of keyboard input-value control step motor, laser range finder carries out the measurement of distance under Stepping Motor Control, and each result who measures is saved in the middle of the RAM, and being superimposed at last obtains trying to achieve area.This laser range finder can be measured the area of specific region automatically, is not subjected to the restriction of region shape, need not manually start to cut apart.Keyboard input-value N passes to single-chip microcomputer, the angle of the each rotation of Single-chip Controlling stepper motor.The every rotation of stepper motor once, laser range finder is finished once the measurement of distance, each result who measures is kept in the middle of the RAM.Finish the measurement of distance when laser range finder after, according to the data in the middle of the RAM, single-chip microcomputer is finished the calculating of area.Use sine and calculate each little leg-of-mutton area, then all little leg-of-mutton areas are stacked up, promptly obtain the area of trying to achieve, single-chip microcomputer send display device output with its value then.
The calculation flow chart of area is as shown in Figure 2:
1) keyboard input digit, this numeral stepper motor number of times that laser range finder is measured that rotates a circle, the rotation of Single-chip Controlling stepper motor.Such as, N=720, stepper motor rotates once every 0.5 degree, and laser range finder carries out once the measurement of distance; N=1440, stepper motor rotates once every 0.25 degree, and laser range finder carries out once the measurement of distance.Each angle of measuring
2) laser range finder carries out the measurement of distance under Stepping Motor Control.
3) each measurement result is saved among the RAM.
4) reference area.The angle of each rotation is very little, the approximate area that replaces irregular figure with leg-of-mutton area.
5) show the area value that calculates.
