Abstract
The invention provides a technical scheme of a roller type length measurement device. The roller type length measurement device comprises a roller and a casing fixing the roller and is characterized in that the roller is fixed at the front end of the casing, an angle sensor is arranged on the roller, the angle sensor is connected with a single-chip microcomputer, the single-chip microcomputer is connected with a display, the display is fixed on the top of the casing, a plurality of circular grooves are arranged on two sides of the casing, a power supply is arranged at the rear end of the casing, and the power supply is connected with the single-chip microcomputer. The roller type length measurement device is simple in operation and high in measurement precision, does not require multi-user assistance, enables one user to finish measurement and saves labor and materials.
Description
Technical field
What the present invention relates to is a kind of instrument of measuring length, especially a kind of roller type length-measuring appliance.
Background technology
In the prior art, known technology is that people are when measuring object length, typically use the instrument measurements such as meter ruler, when the length of object was long, meter ruler length was inadequate like this, just needed repeatedly to measure, need many people to assist, complex operation not only, and affect measuring accuracy, this is the existing weak point of prior art.
Summary of the invention
Purpose of the present invention is exactly for the existing deficiency of prior art, and provides a kind of technical scheme of roller type length-measuring appliance, the measurement mechanism of this scheme, simple to operate, measuring accuracy is high, does not need many people to assist, one people can finish, and has saved manpower and materials.
This programme is achieved by the following technical measures: a kind of roller type length-measuring appliance, include roller, the housing of fixed idler whell, the characteristics of this programme are: described roller is fixed on the front end of housing, be provided with angular transducer on the roller, described angular transducer is connected with a single-chip microcomputer, described single-chip microcomputer is connected with a display, described display is fixed on the top of housing, be provided with the groove of a plurality of circles in the both sides of housing, rear end at housing is provided with power supply, and described power supply is connected with single-chip microcomputer.Described single-chip microcomputer is AT89C52.Described display is liquid crystal display.Power supply is direct supply.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing in this scheme, roller is arranged, be provided with angular transducer on the roller, the number of turns that the roller that can survey timely rolls, angular transducer passes the signal along to single-chip microcomputer, and single-chip microcomputer just can obtain the distance that housing moves according to the number of turns that roller rotates, show by display, fluted on the housing, the staff can hold housing, avoids landing.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and significant progressive, the beneficial effect of its enforcement also is apparent.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
Among the figure, 1 is roller, and 2 is housing, and 3 is angular transducer, and 4 is display, and 5 is power supply, and 6 is groove.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
Can find out by accompanying drawing, the roller type length-measuring appliance of this programme, include roller 1, the housing 2 of fixed idler whell 1, described roller 1 is fixed on the front end of housing 2, be provided with angular transducer 3 on the roller 1, described angular transducer 3 is connected with a single-chip microcomputer, described single-chip microcomputer is connected with a display 4, described display 4 is fixed on the top of housing 2, be provided with the groove 6 of a plurality of circles in the both sides of housing 2, be provided with power supply 5 in the rear end of housing 2, described power supply 5 is connected with single-chip microcomputer.Described single-chip microcomputer is AT89C52.Described display 4 is liquid crystal display.Power supply 5 is direct supply.
The present invention is not limited in above-mentioned embodiment, and the variation that those of ordinary skills make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
