Abstract
The utility model discloses a device for measuring the length of an object with regular movement through photoelectric detection, belonging to the electromechanical class. The device mainly comprises a control core, two groups of counter-emission infrared transmitters-receivers, a serial port, a power supply unit, a keyboard unit and an LCD (liquid crystal display) unit, wherein the control core is a 51-series single chip; and each counter-emission infrared transmitter-receiver consists of an infrared luminous tube unit and an infrared receiving unit. For the device, the two groups of counter-emission infrared transmitters-receivers detect the movement situation of the object; the single chip is used for timing; the length of the moving object can be calculated by the distance value between the two detectors; the LCD module can display the length of the object and is provided with a circuit for measuring the length of the object with regular movement through photoelectric detection, therefore, the device has the advantages of simple structure, high reliability, low cost, etc.
Description
Technical field
The utility model relates to electrical category, measures the device of regular mobile object length for providing a kind of by Photoelectric Detection, refers to pass through the device that Photoelectric Detection measure regular mobile object length of photoelectricity as detection means especially.
Background technology
(1) along the overall measurement direction rule is installed, is come gauge length by the scale size of object process.
(2) become vision signal with the CCD photosensitive imaging and with signal transition,, after the microprocessor processing, obtain the physical length that object is measured through mould/number conversion.
(3) use the displacement of polychromatic light radiation of light source modulating device responsive objects to check object length so that change the distribution spectral content of the light that arrives detecting device.
(4) displacement detector of employing optical profile type is checked object length by the relative position of a main scale and an indicator scale.
Yet, existing regular mobile object length measurement method structure comparatively complicated some also to use as CCD photosensitive imaging device etc. higherly than the expensive device cost, when measuring, exist and use inconveniently, measure shortcomings such as out of true.
