Structure is simple, small volume, frequency response are wide, output voltage change greatly with long service life the advantages of, therefore, measurement, automate,
The field such as computer and information technology is widely used.
People make wheeled type distance measuring apparatus using the principle of Hall effect in the prior art, and this wheeled type distance measuring apparatus is mainly used in
The upper size on ground is measured, the switch change detection pulse number produced when it is rotated on the ground by wheel, by calculating
Wheel girth and perforate number calculate distance.
Hand-held type miniature wheeled type distance measuring apparatus be mainly used in measurement small article size, such as casing, furniture, still
The problem of the meeting producing ratio of hand-held type miniature wheeled type distance measuring apparatus is more, such as after being quickly measured, wheel leaves measuring surface
Afterwards because the inertia of rotation can allow wheel to be rotated further, very big error can be now produced, also is difficult to accomplish anti-inside machine in addition
The effect of dirt and waterproof.
The content of the invention

Magnetic device, at least one pair of hall device being engaged with the polarity of magnetic device, Hall device are mounted with wheel seat
The heat treatment that magnetic device is produced when part is by detecting that measurement wheel is rotated, which is exported, gives control circuit, calculates the distance of measurement.
In the preferable embodiment of the present invention, both sides are each provided with notch, turn of the measurement wheel on the wheel seat
The two ends of moving axis are placed in the notch of both sides, rotary shaft can along notch activity, make measurement wheel can away from or close to hall device.
In the preferable embodiment of the present invention, spring pressure is additionally provided between the rotary shaft and wheel seat of the measurement wheel
Contracting part, measurement wheel is away from hall device under the effect of spring-compressed part, and measurement wheel may move close to Hall device in stress
Part.
In the preferable embodiment of the present invention, be also equipped with interactive keyboard and display screen on housing, distinguish all with
Internal control circuit connection, interactive keyboard is to switch instrument and arrange parameter, and control circuit output result is on a display screen
Display.
In the preferable embodiment of the present invention, a trigger switch is additionally provided with wheel seat, detection measurement wheel
It is close, to trigger the work of hall device, control circuit and display screen.
Having technical effect that for the preferable technical scheme of the present invention, adopts the measurement wheel for the device that is magnetic and with Check up polarity
Hall device realizes wheeled ranging, wheel leave hall device after measuring surface detection it is also all when interrupt, prevent measurement wheel
Inertia, which is rotated, can produce very big error, and instrument internal can also accomplish good dust-proof and waterproof effect in addition.

Part can not detect the magnetic in measurement wheel.
Fig. 2 is state of the rangefinder in measuring surface in embodiment.
Fig. 3 is the partial structurtes diagram one of the rangefinder in embodiment.
Fig. 4 is the partial structurtes diagram two of the rangefinder in embodiment.
Embodiment
Technical scheme is described in detail with specific embodiment below in conjunction with accompanying drawing, so that the skill of this area
Art personnel can understand the complete understanding present invention.
Shown in reference picture 1-4, the present embodiment is a kind of hand-held wheeled type distance measuring apparatus, includes housing 1, in the corner of housing
Set and rotatable measurement wheel 3 is installed on wheeled base 2, wheel seat, the circumference side of measurement wheel, which is fixed with, to be alternately arranged and polarity
Opposite magnetic device 31, is mounted with the hall device 4 being engaged with the polarity of magnetic device for a pair, Hall on wheel seat
The heat treatment that magnetic device is produced when device is by detecting that measurement wheel is rotated, which is exported, gives control circuit, calculates the distance of measurement.
Interactive keyboard 5 and display screen 4 are also equipped with housing, is all connected respectively with internal control circuit, interactive keyboard is to open
Instrument and arrange parameter are closed, control circuit output result is shown on a display screen.
Magnetic device 31 in the present embodiment is magnet, and magnet is evenly distributed on measurement wheel circumference sideways, N poles and S poles
Magnet is alternately arranged, and magnet is shaped in measurement wheel during making, and hall device 4 is two, and N poles and S poles are can detect respectively
Heat treatment.
Both sides are each provided with notch 21 on wheel seat 2, and the two ends of the rotary shaft 32 of measurement wheel are placed in the notch 21 of both sides, turn
Moving axis 32 can along notch activity, make measurement wheel can away from or close to hall device.Also set between the rotary shaft and wheel seat of measurement wheel
Spring-compressed part 22 is equipped with, measurement wheel is away from hall device under the effect of spring-compressed part 22, and measurement wheel can in stress
Move closer to hall device.
It is additionally provided with a trigger switch on wheel seat, not shown in trigger switch figure, it is used to detect connecing for measurement wheel
Closely, the work to trigger hall device, control circuit and display screen.
It is when resting, outwards to be flicked by measurement wheel by spring-compressed part, Hall device that it, which measures the process realized,
The illegal magnetic signal detected in measurement wheel of part, so the state that measurement wheel is left in clutch, it is impossible to detect magnetic
Variable signal, even if measurement wheel is rotated or the rotation of other external force because of inertia, nor affects on the result of measurement.
When starting measurement, measurement wheel stress is moved inward, while can add a trigger switch, is allowed and is controlled circuit work
Make, triggering processor starts to detect signal.Hall device can detect N and the S signal of the magnetic in measurement wheel, before a little also
The S polar regions allowed in measurement wheel should be debugged in advance and N polar regions are mutually corresponding with hall device respectively, all the time in N, S
Or S, N-state, the mode that can now cross counting detects N, the variable quantity of S polarity, while can be become by the NS polarity of measurement wheel
Change judges that measurement wheel is advance or retrogressing.
For example when the polarity that the first two hall device is detected is respectively N poles and S poles, this goes ahead, and is detected as S to N
Change, this walk backward then be N to S change, phase place change is just on the contrary, so by recognizing that phase place change can obtain
Direction.Calculating, which can be crossed, just can obtain the distance that measurement wheel is walked.Apart from the magnetic spacing * magnetic numbers of alternations of computing formula=wheel.
Because wheel can be placed in outside completely, only have magnetic field to be connected with enclosure interior, magnetic field is because that can penetrate non magnetic material
Material.So can so carry out good waterproof, dust-proof effect.
Above example, preferably embodiment only of the invention, but protection scope of the present invention are not limited to
This, any one skilled in the art the invention discloses technical scope in, the change that can readily occur in or replace
Change, should all be included within the scope of the present invention.Therefore, protection scope of the present invention should be with the protection of claims
Scope is defined.
