Referring to fig. 1, a measurement principle of an electronic inclinometer according to an embodiment of the present invention is as follows:
the electronic inclination measuring device is vertically arranged on an object to be measured, when the object to be measured is vertical, light rays emitted by a laser emitter 5-3 in a measuring circuit 5 irradiate on a photosensitive receiving diode 6-2 of a display circuit 6 through a through hole 2-11 in a partition plate 2-1, so that a loop of the display circuit 6 is conducted, a vertical direction indicator lamp 6-3 is lightened, and the object to be measured is in a vertical state; when an object to be detected inclines, the ball body 3-3 rotates on the ball seat 3-5 and drives the laser emitter 5-3 to incline synchronously through the laser seat 4, the photosensitive receiving diode 6-2 of the display circuit 6 cannot receive a light source signal to cause the circuit of the display circuit 6 to be disconnected, the vertical direction indicator lamp 6-3 is turned off, and the object to be detected is judged to be in a non-vertical state through the turning-off of the vertical direction indicator lamp 6-3. That is to say, whether the verticality of the object to be detected is in a vertical state is judged by turning on or off the vertical direction indicator lamp 6-3, and the method has the advantages of simplicity, convenience and quickness in judging the verticality of the object to be detected. The upper shell cavity 2-4 is required to be non-transparent, so that interference on judgment of the verticality of the object to be detected caused by the fact that the photosensitive receiving diode 6-2 receives an external light source is avoided.
When an object to be measured inclines, the ball 3-3 rotates on the ball seat 3-5 to synchronously drive the pressure plate 3-4 to incline, the inclined pressure plate 3-4 is pressed down onto the piezoresistor 5-1 through the contact 3-44 on the pressure plate, the piezoresistor 5-1 generates different resistance values under the action of different pressures, the current value generated by the resistance value change of each measuring branch is measured through the ammeter 5-2, and then the direction or directions of the object to be measured are reflected through the current values. At the moment, the inclination angle of the object to be measured can be converted according to the relation between the current value and the inclination angle so as to measure the numerical value of the specific inclination angle of the object to be measured. When the object to be measured inclines, the inclination angle of the object to be measured can be converted according to the relation between the current value and the inclination angle by judging the inclination direction of the object to be measured through the current value change of the ammeter 5-2 in the measuring branch, so that the numerical value of the specific inclination angle of the object to be measured is measured, and the method has the advantage of high measurement precision.
When the pressing plate 3-4 is inclined in one or more of the front, rear, left, and right directions, it can be judged that one of the front and rear directions is inclined by turning on or off the inclined direction indicator lamp in the front-rear direction, and it can be judged that one of the left and right directions is inclined by turning on or off the inclined direction indicator lamp in the left-right direction. For example, if the tilt indicator lamp is turned on to indicate that the front and the left are tilted, the turn-off state of the tilt indicator lamp indicates that the rear and the right are tilted; of course, turning off the tilt indicator light may indicate that the front and left sides are tilted, and turning off may indicate that the rear and right sides are tilted. Wherein the pressure plate 3-4 is inclined in at least one direction and at most three directions.
