专利摘要:
PURPOSE: A one-axis horizontal sensor is provided to reduce parts count and simplify structure, while obtaining stability in detection. CONSTITUTION: A semi-circular film(5) and an air chamber(4) are arranged perpendicularly to a central axis(6), and the central axis has both ends fixed so that the central axis is rotatable. The semi-circular film has a wide variety of shapes having bright and dark sides. A printed circuit board(3) is fixed to the bright and dark portion of the semi-circular film, in such a manner that a photo-coupler(7) and a light source(8) are opposed each other, centering from the film. Thus, the air chamber fixed perpendicularly to the central axis always moves in a vertical direction with respect to a horizontal plane. Tilt angle of the bottom surface is calculated by measuring the intensity of a light source(8) through the bright and dark sides of the semi-circular film.

1-axis horizontal sensor {1-axis inclino sensor}
[3] There are many types of angle sensors, but each one has a complicated structure and precise cutting-edge method, which causes the failure and at the same time is expensive and complicated to use.
[4] Sensors with a method of measuring the position of bubbles in a liquid substance are not easy to measure the potential of the liquid and are only for horizontal posture control with zero inclination angle but are also not acceptable. Changes in the vertical position of the liquid surface due to expansion and contraction of the liquid caused by changes in the ambient temperature of the liquid, changes in the properties of the liquid, and instability of the contact surface due to the surface tension of the liquid cause errors of precision and reproducibility. The problem is that these sensors cannot be made with high precision because the liquid surface difference only produces small changes in output.
[5] There are sensors that measure the position of bubbles due to the reflection of light in the liquid phase, but they also have many problems, and there are many difficulties in the measurement of high-level electronic technology and position in terms of precision.
[6] Since angle measurement using magnetic field and mother field is not easy to measure the potential proportional to the magnetic force, conventional angle measurement involves many electronic components, while it is also difficult to correct fine magnetic field distortion and absolute angle measurement. Is difficult.
[7] In view of the above, the present invention can achieve excellent effects with a small number of electronic components, and various applications are possible.
[8] The measurement of the angle is the absolute angle measurement to measure relative to the horizontal plane, and the relative angle measurement to measure the change from any angle to any angle, but the present invention is configured to be able to easily measure the two angles It is possible to express stable and high resolution angle in various systems requiring angle measurement, and it is easier to use as a general sensor as well as a professional sensor rather than the existing expensive sensor. The application of the branch becomes possible.
[1] Fig. 1: Structure diagram of the sensor
[2] Fig. 2: Exposed form of semicircular film
[9] Looking at the detailed configuration of the present invention,
[10] Perpendicular to the central axis 6, a semicircular film 5 made of light and shade and an air chamber 4 are mounted, and both ends of the shaft are fixed with a tip so that the central axis 6 can rotate, and the semicircular film ( 5) can be configured in various shapes, make the contrast with the resolution of the desired angle, light it, and then fix it to the central axis.
[11] An air chamber fixed to the axis 6 by fixing the porter coupler 7 and the light source 8 to the circuit board 3 so as to face each other centering on the film where the contrast portion of the semi-circular film 5 is located. 4) is configured to always move perpendicular to the horizontal plane,
[12] Since the inclination angle of the bottom surface measures the intensity of the light source due to the circular film contrast 5, the inclination of the angle can be calculated, and the resolution of the angle is determined by the digital conversion of the analog photocoupler output voltage.
[13] The change of angle can be divided more finely by the structure and shape of light and shade exposed to semi-circular film, and the + and-angles can be arbitrarily set after setting the center angle.
[14] The output voltage can be measured up to 1/100 degrees or less with a resolution of 11 or 12 BIT in AD conversion.
[15] In this sensor, the micro vibration is attenuated by the liquid substance inside the sensor, and the liquid substance is related to the reaction rate of the angle according to the viscosity.
[16] In the fixed or stationary state, the voltage according to the absolute angle is always output, and even when measuring the relative angle, the changed output voltage is output by the tilt angle.
[17] Always monitor the tilting angle of buildings, bridges, tunnels, structures, etc. in that there are no driving parts (motor or gyro) at the time of measuring the angle, no substance sensitive to temperature, and a semi-permanent life. You can expect excellent effects when you use it, such as posture control of machinery robot, angle cutting in general woodworking, tilt measurement in civil engineering, calculation of position control in computer, computational control in construction, ship, aviation, furniture arrangement, astronomy, or computer There are many applications such as posture control.
