[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-7 , an embodiment provided by the present invention:

[0029] An Internet of Things inclination monitoring device includes a base 11, an installation chassis 12, a placing plate 14 and an electrical bin 15. The surface of the base 11 is provided with a first groove 1, a second groove 2, a third groove 3 and a fourth groove 4. The surface of the placing plate 14 is provided with a clamp 13. The bottom end of the placing plate 14 is fixedly connected with an angle steel 16. The surface of the installation chassis 12 is provided with a screw hole, and the inner side of the screw hole is sleeved with a leveling screw 17. The first groove 1, the second groove 2, the third groove 3 and the fourth groove 4 form a cross-shaped groove on the base 11, and the base 11 is fitted with a measuring device through the cross-shaped groove. When the base 11 is installed and used, the second groove 2 is located due south, the first groove 1 is located due north, the third groove 3 is located due west, and the fourth groove 4 is located due east. The inside of the electrical bin 15 is provided with electrical components. The electrical components include a signal transceiver module, a calculation and storage module and an inclination measurement module. The signal transceiver module uses an Internet of Things module to send inclination detection signals. The calculation and storage module uses a single-chip microcomputer chip to process the signals received from the inclination measurement module and send them to the Internet of Things module for transmission.

[0030] Furthermore, the screw holes opened on the surface of the mounting chassis 12 are distributed in four groups. The leveling screws 17 are correspondingly connected to the screw holes. The leveling screws 17 are in abutting contact with the surfaces of the mounting chassis 12 and the placing plate 14. Through the connection between the leveling screws 17 and the screw holes, the leveling adjustment of the mounting chassis 12 and the base 11 during placement and use is realized. Under the action of the clamp 13 and the angle steel 16, it can be selected according to the use site and scenario.

[0031] Furthermore, a limiting groove 18 is opened on the surface of the placing plate 14. A clamping block 19 is slidably connected to the surface of the placing plate 14 through the limiting groove 18. A resisting rod 20 penetrates through the surface of the clamping block 19. The clamping block 19 is in abutting contact with the surface of the leveling screw 17. The cross-section of the limiting groove 18 is in a "T" shape. A sliding block is fixedly connected to the bottom end of the clamping block 19, and the sliding block is slidably connected to the limiting groove 18. The clamping block 19 is composed of two parts. The cross-section of one part of the clamping block 19 is in an "L" shape, and the other part of the clamping block 19 is in a plate shape. The resisting rod 20 penetrates through the clamping block 19 and is in abutting contact with the surface of the placing plate 14 through threads. Through the sliding connection between the sliding block on the clamping block 19 and the limiting groove 18, the acting position of the clamping block 19 on the placing plate 14 can be adjusted. Under the abutting contact between the resisting rod 20 and the placing plate 14, the supporting and limiting control of the acting position of the clamping block 19 is realized. Under the action of the clamping block 19, the acting position of the leveling screw 17 on the placing plate 14 can be limited and supported, improving the stability of the mounting chassis 12 during placement and use on the placing plate 14. Inside the cross-shaped groove on the surface of the base 11, there are a linear resistor 5, a liquid storage chamber 6, a protection resistor 7, a constant voltage power supply 8, a current detector 9 and an insulating column 10. The linear resistor 5, the liquid storage chamber 6, the protection resistor 7, the constant voltage power supply 8, and the current detector 9 are all existing products, and their working principles are prior art, so no more description will be made here. The liquid storage chamber 6 stores a conductive liquid, and the specific composition of the conductive liquid is determined according to the environment and climate conditions. The linear resistor 5 and the conductive liquid in the liquid storage chamber 6 are electrically connected to the calculation and storage module.

[0032] When the measuring device is in a horizontal position, the conductive liquid in the liquid storage chamber 6 is in a horizontal state under the action of gravity and does not contact the linear resistor 5, and the circuit is in an open state. The calculation and storage module determines that the monitored object is stable and has not tilted.

[0033] When the measuring device tilts, for example, only tilts in the west (W) direction, the conductive liquid in the liquid storage chamber 6 is in a horizontal state under the action of gravity, and part of the liquid contacts the linear resistor 5, and the circuit is turned on. In the measuring device on the west (W) side, the current flow direction is A->B->C, and the current measurement result on the west (W) side is: Due to different tilting degrees, the position of point B will change, and the value of R AB will also change, and finally the measured I WThe value also changes according to different inclinations; the current measurement result on the east (E) side is: is a fixed value, denoted as I 全 ; the measured values I N and I S of the measuring devices on the north (N) side and the south (S) side have only two states, 0 or I 全 , and the current measurement detector in the measuring device will measure I W , I E , I N , I S The four measured values are transmitted to the calculation and storage module. The calculation and storage module calculates according to the states of the four measured values to obtain the inclination angles in the four azimuth components. The calculation method is: where I0 is the current value measured when the measuring device is in a vertical state.

[0034] According to the angles of the four azimuths, the tipping angle and the tilting azimuth are calculated. OL is the object to be measured for tipping. A perpendicular line LP is drawn from L to the W-E, S-N plane, and the foot of the perpendicular is P. Perpendicular lines are drawn from P to the WE axis and the SN axis respectively, and the feet of the perpendiculars are X and Y. It can be known that the two angles θ1 and θ2 are measured by the WE measuring device and the SN measuring device respectively. Let PL be d. According to geometric knowledge, PX⊥WE, PY⊥SN, LP⊥OP, PX = YO, PY = XO. From the trigonometric relationship, it can be calculated that:

[0036] The inclination angle

[0037]

[0038] The tilting azimuth angle (west-south W-S)

[0039]

[0040] This invention mainly relies on the principle that liquid automatically levels under natural gravity; utilizes the liquid fluid characteristics and high conductivity of conductive liquid to achieve real-time monitoring and alarming of the horizontal condition of the monitored object, uses solar panels and storage batteries to achieve stable power supply for the system, uses IoT cards to achieve real-time reporting of monitoring data, designs a simple and reliable mechanism through basic electrical physics and mechanical geometry principles, powers with solar panels, and uses a single-chip microcomputer and IoT cards to achieve data transmission and monitoring; can achieve low cost, small size, low power consumption, high reliability and durability; after the monitor is deployed, it can be maintenance-free, with low failure rate, and can automatically connect to the network and form a network, and the background automatically monitors to achieve early warning and alarming functions.
