Embodiment 1

[0032] refer to Figure 1-3 , a low-power inclination sensor based on the NB-IOT Internet of Things, including a housing 1, and the housing 1 is respectively provided with a power storage module 2, a charging module 3, a control module 4, a sensor measurement module 5 and a communication module 6, The power storage module 2 is a rechargeable storage battery, the charging module 3 is a solar panel or a USB charging module, the charging module 3 is isolated from other electrical components by a shielding layer 14, an acceleration sensor for measuring inclination changes is arranged in the sensor measurement module 5, and a communication module 6 includes a low-power NB-IoT module and an antenna. The communication module 6 transmits the inclination data measured by the inclination sensor to the terminal display. A flat board 7 parallel to the XY plane of the acceleration sensor is fixed on the bottom of the housing 1. The flat board 7 is connected with a push rod 10 through a spr...

Embodiment 2

[0035]As shown in Figure 2-3, on the basis of Embodiment 1, in order to further improve the accuracy of installation, so that the sensing line is parallel to the axis of the measured surface, a number of evenly distributed pressure sensitive blocks 8 are fixed under the flat plate 7, And the pressure-sensitive sensing blocks 8 are symmetrically distributed in the X and Y directions of acceleration sensing, and the bottom of each pressure-sensitive sensing block 8 is connected with a push rod 10 through a spring 9, and the spring 9 is limited by the slide provided by the housing 1 under the flat plate 7. In the groove 11, the ejector rod 10 is slidingly matched with the chute 11, so that the ejector rod 10 can compress the spring 9 and enter the chute 11 after being subjected to external pressure. The pressure sensitive block 8 is a pressure sensor, and the pressure sensor is X Distributed symmetrically with the Y direction, each pressure sensor is connected with a push rod 10 t...

Embodiment 3

[0038] refer to Figure 6 , on the basis of Example 2, when the installation part is a round shaft or a round pipe, it is usually difficult to install, and it is not easy to determine the X and Y directions of the round shaft. For round shafts or round pipes, it is only necessary to ensure that multiple sets of The pressures detected by the four pressure sensors symmetrical to each other in the Y direction are the same, and the detected pressures are the same, that is, it is determined that the sensing line is parallel to the axis, and the mounting plate 12 is a flexible part. When installing, adjust the Mounting plate 12, after the installation is completed, the mounting plate 12 hugs the round shaft or the round pipe, and the push rod 10 is symmetrically distributed on the arc surface of the round shaft or the round pipe to press the round shaft or the round pipe, so that the inclination sensor of the present invention Firmly fixed on the round shaft or round pipe, compared ...

Abstract

The invention discloses a low-power-consumption tilt angle sensor based on the NBIOT Internet of Things, and relates to the technical field of sensors. The low-power-consumption tilt angle sensor comprises a shell and a mounting plate, the shell and the mounting plate are fastened through bolts to clamp a measured piece 15, and a power storage module, a charging module, a control module, a sensor measurement module and a communication module are arranged in the shell separately. An acceleration sensor for measuring inclination angle changes is arranged in the sensor measuring module, a plane plate parallel to the XY plane of the acceleration sensor is fixed to the lower portion in the shell, a plurality of pressure-sensitive induction blocks which are evenly distributed are fixed to the lower portion of the plane plate, and the pressure-sensitive induction blocks are symmetrically distributed in the X direction and the Y direction of the acceleration sensor. The lower portion of each pressure-sensitive induction block is connected with an ejector rod through a spring. The tilt angle sensor can be used for a long time in various environments, is convenient to install, keeps high-precision measurement, especially outdoors, and can be widely applied to the fields of bridges, unmanned aerial vehicles, ships and the like.

Description

technical field [0001] The invention belongs to the field of sensors, in particular to a low-power inclination sensor based on the NB-IOT Internet of Things. Background technique [0002] The inclination sensor based on the principle of acceleration is the direction of digital development of current inclination measuring instruments. Inclination sensors are very common in people's daily life, involving many applications, and can be used in construction, roads, automobiles, bridges, petroleum, coal mines and geological exploration and other fields. [0003] Generally, in order to improve the measurement accuracy of the inclination sensor, the installation surface of the sensor should be kept parallel to the measured target surface during installation, and the influence of dynamics and acceleration on the sensor should be reduced. For products with a range of ≤60°, please install them horizontally. There are X and Y direction indicator stickers on the front of the sensor. You...
