The active infrared range unit employs the single-chip microcomputer for counting, and controls infrared emission power with moving speed of a detecting object. The dynamic distance between the detecting object and a detected object can be measured, and the measuring accuracy is substantially improved.
Description
Technical field
This paper relates to the range finding field, relates in particular to a kind of infrared active distance measuring equipment.
Background technology
Along with development of electronic technology, microwave radar range finding, ultrasonic ranging and infrared distance measuring laser ranging have successively appearred.Wherein laser ranging is to be radiated at the detecting laser beam master who reflects on the measured object by laser beam to survey distance between thing and the measured object.Owing to be subjected to factor affecting such as boisterous influence the, the movement of dynamic object, pollutions, be that the laser beam detection range on certain power that reflects reduces 1/2-1/3 than the ultimate range that may survey, lose very greatly, influence the degree of accuracy of measurement; The microwave radar ranging technology for military and partial circuits such as equipment that some commercial development is adopted and oscillator are expensive, beaten a drum now and is not opened up the commercial market; Research was done in ultrasonic ranging at home and abroad existing people, owing to adopt special professional component to make its price height, was difficult to promote; Infrared ray has extensive basic physical transfer characteristic-reflection, refraction, scattering as a kind of special light wave.Cut for its technical difficulty for a short time, the cheap performance of installation cost is good, is convenient to civilian popularization.
Summary of the invention
Defective or deficiency at the existence of above-mentioned background technology, the purpose of this utility model is, a kind of infrared active distance measuring equipment is provided, adopt single-chip microcomputer " counting " mode to handle, in addition with the control of main survey thing translational speed to infrared emission power, make the winner survey thing and measured object its spacing under dynamical state can be measured, and accuracy of measurement has had large increase.
In order to realize above-mentioned task, the utility model adopts following technical solution to be achieved:
A kind of infrared ray is distance measuring equipment initiatively, comprises with the single-chip microcomputer being infrared ray transmitter module, infrared echo receiver module, sound and light alarm module, the measured distance display module of control core.Wherein single-chip microcomputer links to each other with power module with infrared ray transmitter module, infrared echo receiver module, sound and light alarm module, measured distance display module respectively.
The utility model also has following other technologies characteristics:
Described single-chip microcomputer is selected the ATmega16L single-chip microcomputer for use.
Described infrared ray transmitter module adopts the infraluminescence pipe, and the infraluminescence pipe adopts model 5308IRC-10.
Described infrared echo receiver module adopts infrared remote receiver HDX2HDX2
Described actual range display module LCD LCDs.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to Fig. 1, a kind of infrared active distance measuring equipment comprises with the single-chip microcomputer being infrared ray transmitter module, infrared echo receiver module, sound and light alarm module, the measured distance display module of control core.Wherein single-chip microcomputer links to each other with power module with infrared ray transmitter module, infrared echo receiver module, sound and light alarm module, measured distance display module respectively.
Single-chip microcomputer of the present utility model is selected the ATmega16L single-chip microcomputer for use, and it comprises 8 AVR microprocessors of high-performance, low-power consumption, advanced risc architecture, erasable 10,000 times of the EEPROM of 512 bytes, four-way PWM, 8 tunnel 10 ADC.
The luminotron of infrared ray transmitter module adopts model 5308IRC-10.
The infrared remote receiver of infrared echo receiver module adopts H-DX2.
The sound and light alarm module is reported to the police to device.
The actual range display module adopts the LCD LCDs.
Power module provides power supply for device.
The utility model is by " counting " mode, measure by the single-chip microcomputer processing, the step of specific implementation is: the infrared ray transmitter module is in emission state all the time, infrared emission tube is determined its emissive power according to the translational speed of registration thing itself, when speed is big, select high-power gear, select the miniwatt gear when low speed moves.In order to remove undesired signal, when infrared remote receiver receives the infrared ray of measured object reflected back for the N time, provide a count enable signal through the processing of circuit single-chip microcomputer, the counter of single-chip microcomputer begins to count with certain frequency; When the infrared ray receiver receives the infrared ray of reflected back for the second time, provide one through the processing of circuit single-chip microcomputer and stop count pulse, counter stops counting.By programming, single-chip microcomputer is handled automatically, multiply by umber of pulse with the cycle of pulse and just obtains launching infrared ray to the mistiming of receiving infrared-ray.Be that t=NT can calculate two distances between the object by two formula.
