Laser reception principle based electronic height instrument

Abstract

The invention relates to a laser reception principle based electronic height instrument. The laser reception principle based electronic height instrument has much limitation on its application due to the defects that the instrument is easily disturbed externally, inaccurate and the like. The laser reception principle based electronic height instrument comprises laser emission heads, laser reception heads, a main circuit board and support rods. The support rods are used for height adjustment of the height instrument. The laser emission heads are connected with a driving board. The laser reception heads are connected with the main circuit board. According to the height instrument, touch height is detected through vertical laser arrays; when lasers at a certain height are blocked off, the laser reception heads at the corresponding height do not receive correlation laser signals, and thus, the highest touch height of a testee can be judged. By the laser reception principle based electronic height instrument, the problems of low sensitiveness, low accuracy and incapability of moving of existing height instruments are solved effectively.

Description

Technical field [0001] The invention belongs to the technical field of automation equipment. It relates to an electronic height profiler based on the principle of laser receiving. Background technique [0002] In the current market, the most common height toucher is an electronic height toucher based on the capacitive touch principle, and there is also an electronic height toucher based on the principle of infrared detection. [0003] Electronic height detectors based on the principle of infrared detection, because infrared detectors are easily interfered by outdoor sunlight or indoor lights, their reliability is worse, and their use range is smaller. Now they are rare in the market. The electronic touch height device based on the capacitive touch principle has the advantages of simple structure and low cost. However, its shortcomings such as susceptibility to external interference and inaccuracy also lead to many limitations in its application. For example, in some formal tests...
