Description
Technical field
The utility model relates to a kind of survey instrument, particularly a kind of electronic angle gauge.
Background technology
Traditional protractor does not have display device, only determine angular dimension with the scale of operator's the direct observation angle rule of eyes, in the time measuring, because of difference or the visual angle difference of survey crew, make measuring error larger, precision is relatively low, and be subject to the correct degree impact of gauger's skill level and operation, easily cause artificial deviation, the occasion of measuring accuracy being had relatively high expectations at some cannot provide relatively accurate measurement data, is unfavorable for the production of high-accuracy product.
Utility model content
The utility model proposes a kind of electronic angle gauge, solve standing crop hornwork measuring accuracy poor, be subject to the problem of Human disturbance introducing error.
The technical solution of the utility model is achieved in that
A kind of electronic angle gauge, comprises semi-circular plate, pointer, rotational potentiometer, A/D convertor circuit, computing circuit, display device and supply unit; Described rotational potentiometer is fixedly installed in the center on base on semi-circular plate, and one end of described pointer is fixedly connected on the knob of rotational potentiometer; Described rotational potentiometer is electrically connected with described A/D convertor circuit, and described A/D convertor circuit is electrically connected with described computing circuit, and described computing circuit is electrically connected with described display device.
Further, described semi-circular plate is along the circumferential direction provided with angle index.
Further, the length of described pointer equals the radius of semi-circular plate.
Further, the other end of described pointer is top shape.
Known by above description, the utility model compared with prior art, the utlity model has following advantage:
The utility model converts digital signal by the resistance value that rotational potentiometer is changed to by A/D convertor circuit, will, by digital signal is carried out to computing, convert angle value to and show by display device, has intuitively, measures the advantages such as accurate.
