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.

Why electronic altitude touch machine based on capacitance touch principle is difficult to the requirement meeting regular test and examination, and reason is: 1) poor sensitivity, if particularly touch not reaction with nail position, causes often occurring dispute in penalty; 2) capacitive altitude touch machine is also easily subject to external interference, all more responsive to environment temperature temperature and humidity, poor reliability; 3) be substantially all wall-hanging, can not move, height can not be adjusted, use inconvenience; 4) LCDs is too small, clear not.
Summary of the invention
The present invention is directed to capacitance present and touch electronic altitude touch machine poor sensitivity, not accurately, the shortcoming heightened can not be moved, provide one and can accurately measure and adjustable laser altitude touch machine.
The present invention includes laser beam emitting head, laser pick-off head, main circuit board and support bar; Support bar is used for the adjustment of altitude touch machine height; Laser beam emitting head is connected with drive plate, and laser pick-off head is connected with main circuit board; Described laser altitude touch machine adopts the laser array of vertical direction to check altitude touch height; When the laser of a certain height is blocked, the laser pick-off head of respective heights does not receive correlation laser signal, so just can judge the highest altitude touch height of measured.
Described laser array adopts n to detect the maximum height of altitude touch to Laser emission receiving system, installs a pair Laser emission and receiving sensor in altitude touch machine every distance d; The highest described altitude touch height H=h+(N-1) * d, h be a pair, bottom laser sensor respective heights, N is the numbering of the highest laser array touched of finger of tested personnel, N >=1.
Electronic altitude touch machine control method based on laser pick-off principle comprises the following steps:
, start up system run (open system power supply);
, whether the amplifier that reads on all laser pick-off heads of control program on main circuit board export the signal of telecommunication, judges whether current all laser all receives (namely whether having laser to be blocked), if all do not received, then jumps to
, otherwise jump to
;
, continue to read the amplifier of all laser pick-off heads and whether export the signal of telecommunication, judge current so whether laser all receives, if all do not received, then jump to
, otherwise continue to read the signal of telecommunication;
, control program on main circuit board read by the signal of telecommunication that amplifier exports and currently do not received the accurate numbering of the receiver of laser and send to associated satellite equipment;
, LED display shows the information such as altitude touch height, qualified height and test result after control program work on;
, continue to read the amplifier of all laser pick-off heads and whether export the signal of telecommunication, judge current so whether laser all receives, if all do not received, then jump to 7., otherwise continue to read the signal of telecommunication;
, control program on main circuit board read by the signal of telecommunication that amplifier exports and currently do not accepted the accurate numbering of the receiver of laser and send to associated satellite equipment;
8., next constantly repeat
-
operation.
Furtherly, after associated satellite equipment receives the accurate numbering of the receiver not receiving laser, the actual height corresponding to this numbering is calculated according to algorithm.If receive multiple numbering, then the standard of getting maximum height and default contrasts, and it is qualified to judge whether, and is shown on LED display by specifying information.
Beneficial effect of the present invention: laser sensor is for the accurate location of height of touch, and support bar is used for the adjustment of altitude touch machine height.The technical program achieves the Height Adjustment of accurate location and the altitude touch machine of touch and doing by the launch and accept of laser and support bar, because laser has fabulous monochromaticjty, one-way and anti-infection property, laser altitude touch machine is hardly by external interference, its reliability is that other scheme can not be compared, also can solve the problem can not reacted when condenser type altitude touch machine nail touches simultaneously, ensure that this altitude touch machine can be applied to each large occasion.
In a word, a kind of described in the technical program accurately can measure and adjust the equipment of height, efficiently solves current altitude touch machine poor sensitivity, accurate not, irremovable problem.
