Description
Technical field
The utility model belongs to the ranging technology field, is specifically related to a kind of distance-measuring device.
Background technology
Along with science and technology development with rapid changepl. never-ending changes and improvements, to needing accurate distance or measurement of length in the use of various instruments.Development is distance-measuring device miscellaneous thereupon.But because hardware constraints, the distance that most of distance meters can be measured can not satisfy client's demand by chance; The measuring instrument that can meet consumers' demand such as range finder using laser, can reach accurate, remote measuring distance; But its price is higher, and volume is bigger; Carry also inconvenience, the thing followed, in use; Because structure is comparatively complicated, user's program that operates is comparatively loaded down with trivial details, has increased Measuring Time.
The utility model content
To the problems referred to above; The utility model provides a kind of distance-measuring device, and testee places the preceding certain distance of this distance-measuring device, and the user is positioned at this distance-measuring device other end of this testee relatively; This distance-measuring device comprises: the image height measuring appliance is measured; Be used to measure the height of testee imaging, the image distance measuring appliance is measured, and is used to measure the distance of user's eyes to this imaging; Single-chip microcomputer, the height of preset this testee; This single-chip microcomputer receives the height and the distance of these user's eyes to this imaging of this imaging, and calculates the concrete numerical value of this certain distance according to the altitude gauge of this preset testee.
Wherein, this image height measuring appliance comprises a capacitor grid transducer.
Wherein, this image height measuring appliance has a vernier scale, and this capacitor grid transducer is measured the displacement that this vernier moves, and this displacement parameter is passed to this single-chip microcomputer.
Wherein, when a starting point of this measuring appliance and this vernier and testee became a horizontal line, the displacement parameter that this single-chip microcomputer receives was exactly the height of this imaging.
Wherein, this image distance measuring appliance has infrared distance measurement probe, is used to measure the distance of this distance-measuring device to user's eyes.
Wherein, this this distance-measuring device of infrared distance measurement probe measurement is to the distance of user's eyes, and this single-chip microcomputer receives the parameter of this distance, and transfers to this single-chip microcomputer.
Wherein, more comprise supervisory keyboard.
Wherein, more comprise a LED display.
Description of drawings
Fig. 1 is the structure drawing of device of the utility model.
Embodiment
Fig. 1 is the utility model distance-measuring device structural drawing, before testee places distance-measuring device, and keep certain distance, and the user is positioned at this distance-measuring device other end of this testee relatively.This distance-measuring device has the image height measuring appliance of an employing capacitor grid transducer.This distance-measuring device is lifted; Move its position; Adjust this vernier scale b simultaneously and become a horizontal line with the vernier scale b and the object being measured of this image height measuring appliance until the start position a of this distance-measuring device; This moment this vernier scale b apart from d, this capacitor grid transducer measures the position d that this vernier scale b moves, and sends this moving parameter d the single-chip microcomputer with range converter of this measurement mechanism to.This single-chip microcomputer changes into this parameter d computing the height t of testee imaging.
The image distance measuring appliance of this distance-measuring device is equipped with the distance of infrared distance measurement probe measurement user eyes to this imaging through front end.Specific as follows, the user is positioned over horizontal eye position with this distance-measuring device, and as far as possible away from eyes, and make device vertical, the vernier scale b on the image height on the carriage is measured.This infrared distance measurement probe receives the infrared ray that user's eyes are sent, and is sent to this single-chip microcomputer.When vernier scale b starting point and testee become a vertical line up and down, press the button of supervisory keyboard, single-chip microcomputer gather user's eyes to this imaging apart from l.
The height h of this tested physics of meeting desire storage in this single-chip microcomputer.
Can draw according to geometrical principle: the distance/image height of object distance=object height * imaging, in the utility model, the object distance=hxl/t of measured object.The object distance of the measured object of measuring is presented on the LED display.
Measuring distance device in the utility model more can comprise a six press keys and a LED display.
Wherein, the whole device of the distance-measuring device in the utility model is designed to the form of slide calliper rule, and volume is little, is easy to carry.
This device distance measuring precision depends mainly on the selection of target; The known altitude of select target is a key parameter, is actually used in mainly to be used for measurement target people's distance, can select a plurality of target measurements; Average, to reduce the range observation error that the height evaluated error is brought.
What should explain at last is: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this instructions has carried out detailed explanation with reference to the above embodiments to the utility model,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of the spirit and the scope of the utility model, and it all should be encompassed in the claim scope of the utility model.
