[0016] 2. Through the connection mechanism set, the controller in the initial state controls the electromagnet to be energized, the button battery provides power for the electromagnet, and the card block is made of iron material.

When the cylinder is fully inserted into the column groove and can no longer be lowered, the card slot is exactly at the position of the card block, and then the controller controls the electromagnet to cut off the electromagnetic suction and disappear. At this time, the spring resets and pushes the card block out of the empty slot and into the inside of the card slot, which is conducive to completing the connection between the placement box and the box cover by fixing the cylinder. When the placement box needs to repair the internal circuit board or other electrical components, the electromagnet is energized again, and then the card block leaves the card slot under the action of the magnetic suction force. At this time, the cylinder is pulled by the handle, and then the cylinder leaves the inside of the rectangular block, which is conducive to completing the separation of the placement box and the box cover, and is convenient for repairing the inside of the placement box. 3. Through the moisture-proof mechanism, a desiccant is placed inside the storage box before the box cover is connected to the placement box. The desiccant helps prevent moisture from being generated inside the placement box. When the box cover is connected to the placement box, the pressure plate on the inside of the box cover enters the inside of the groove. The diameter of the pressure plate is one-third of the groove. When the pressure plate enters the groove, the pressure plate presses the airbag and then a part of the airbag is squeezed out of the groove. The extruded part helps fill the gap at the connection between the box cover and the placement box, which helps prevent dust or moisture from entering through the gap.

[0021] A pressure sensor-based pipeline liquid level Internet of Things monitoring device comprises: a container 1, wherein liquid is stored in the container 1, a mounting bracket is provided at the bottom of the container 1, a placement box 2 is provided at the front of the container 1, the placement box 2 can be connected to the container through a rope or a suction cup, or fixed on a wall through a hole in an outer shell, or can be placed anywhere within 1 meter and not on the container, the placement box 2 is connected to a power plug 3, the container 1 is connected to a pipeline 4, the pipeline 4 is connected to a three-way head 5, a pressure sensor 6 is installed on the top of the three-way head 5, the placement box 2 is connected to an electric wire 8 and a data transmission line, and the pressure sensor 6 is connected to the placement box 2 through the electric wire 8 and the data transmission line.

[0022] It can be concluded that the placement box 2 is hung in front of the container 1 by a rope, or can also be attached to the container 1 by a suction cup, and the power plug 3 is plugged in to power on the Internet of Things monitoring device. The device collects the voltage value of the pressure sensor in real time through the ADC module circuit in the integrated circuit. The processor in the circuit calculates the liquid level depth corresponding to the current pressure according to the current pressure value received by the pressure sensor 6, and then sends the current liquid level depth to the Internet of Things platform through the communication module. The platform processes the current value accordingly, such as the current value is less than a certain value to trigger an alarm or calculates the current liquid level by how much it has increased or decreased by the previous value, etc., so as to perform corresponding actions. The device is not easily interfered with, so that the monitoring information is accurate. The processor calculates the liquid level depth corresponding to the current pressure according to the current pressure value, which solves the problem of discovering that the liquid in the container is exhausted, and solves the problem that it is difficult to discover or discover late after the pipeline connecting the container or the container leaks or the liquid in the container is stolen, and solves the problem of unauthorized liquid filling.

[0023] Furthermore, a circuit board 10 is installed inside the placement box 2, and a moisture-proof mechanism is provided inside the placement box 2 to prevent the circuit board 10 from getting damp and unable to work. The moisture-proof mechanism includes a storage box 11 provided inside the placement box 2, and the storage box 11 is provided with an opening to absorb moisture. The front of the storage box 11 is provided with an openable cover, and a desiccant is provided inside the storage box 11. The desiccant can be easily replaced by opening the cover. A controller 12 is provided inside the placement box 2, and a humidity sensor 14 and a temperature sensor are installed on the circuit board 10.

[0024] It should be noted that the humidity sensor 14 and the temperature sensor are electrically connected to the controller 12 . The humidity sensor 14 is used to monitor the humidity inside the placement box 2 . The signals monitored by the humidity sensor 14 and the temperature sensor are transmitted to the controller 12 .

[0025] Furthermore, the placement box 2 is provided with a groove 17 , and an air bag 18 for sealing and dustproofing is placed inside the groove 17 . A rectangular pressing plate 19 is provided on the inner side of the box cover 9 , and the width of the pressing plate 19 is one third of the width of the groove 17 .

[0026] Specifically, before the box cover 9 is connected to the placement box 2, a desiccant is placed inside the storage box 11. The desiccant helps prevent moisture from being generated inside the placement box 2. When the box cover 9 is connected to the placement box 2, the pressing plate 19 on the inner side of the box cover 9 enters the interior of the groove 17. The diameter of the pressing plate 19 is one-third of the groove 17. When the pressing plate 19 enters the groove 17, the pressing plate 19 presses the airbag 18 and then a part of the airbag 18 is squeezed out of the groove 17. The squeezed part helps fill the gap at the connection between the box cover 9 and the placement box 2, which helps prevent dust or moisture from entering through the gap.

[0027] In addition, the placement box 2 is provided with a box cover 9, and the placement box 2 is connected to the box cover 9 through a connecting mechanism, and the connecting mechanism includes rectangular blocks 23 at the four corners of the placement box 2, and the rectangular blocks 23 are provided with column grooves 24. The four corners of the placement box 2 are slidably connected with cylinders 25, and a handle 26 is fixed at one end of the cylinder 25, and the cylinder 25 is provided with a card slot 27.

[0028] In addition, an elastic sealing ring 28 is provided at the top of the column groove 24, a replaceable button battery 29 is installed in the rectangular block 23, empty grooves 31 are provided on both sides of the column groove 24, an electromagnet 32 ​​is fixed inside the empty groove 31, a spring 33 is fixed on one side of the electromagnet 32, a card block 34 cooperating with the card slot 27 is provided inside the empty groove 31, and one end of the spring 33 is fixedly connected to the card block 34.

[0029] It is emphasized that the controller 12 in the initial state controls the electromagnet 32 ​​to be energized, the button battery 29 provides power for the electromagnet 32, and the card block 34 is made of iron material. When the electromagnet 32 ​​is energized, the magnetic force adsorbs the card block 34, and the rebound force of the spring 33 is less than the suction force brought by the electromagnet 32 ​​to the card block 34, so the spring 33 is compressed at this time and the card block 34 is adsorbed and retreated, and then the cylinders 25 at the four corners of the box cover 9 are inserted into the column grooves 24 of the rectangular block 23. When the cylinder 25 is completely inserted into the column grooves 24 and cannot be lowered any further, the card grooves 27 are just located at the position of the card block 34, and then the controller 1 2 The electromagnetic attraction of the control electromagnet 32 ​​disappears. At this time, the spring 33 is reset and pushes the block 34 out of the empty slot 31 into the inside of the slot 27, which is conducive to completing the connection between the placement box 2 and the box cover 9 by fixing the cylinder 25. When the placement box 2 needs to repair the internal circuit board 10 or other electrical components, the electromagnet 32 ​​is energized again, and then the block 34 leaves the slot 27 under the action of the magnetic attraction. At this time, the cylinder 25 is pulled by the handle 26, and then the cylinder 25 leaves the inside of the rectangular block 23, which is conducive to completing the separation of the placement box 2 and the box cover 9, and is convenient for repairing the inside of the placement box 2.

[0030] Working principle: The placement box 2, power plug 3, pipe 4, tee 5, pressure sensor 6, wire 8, and integrated circuit constitute the Internet of Things monitoring device. The placement box 2 can be connected to the container through a rope or a suction cup, or fixed on the wall through the hole of the shell, or placed anywhere within 1 meter and not on the container. Plug in the power plug 3 to power on the Internet of Things monitoring device. The device collects the voltage value of the pressure sensor in real time through the ADC module circuit in the integrated circuit. The processor in the circuit calculates the liquid level depth corresponding to the current pressure according to the current pressure value received by the pressure sensor 6, and then sends the current liquid level depth to the Internet of Things platform through the communication module. The platform processes the current value accordingly, such as the current value is less than a certain value to trigger an alarm, or calculates the current liquid level by how much it has increased or decreased by comparing it with the last value. How much, etc., so as to perform corresponding actions. The device is not easily disturbed, so that the monitored information is accurate. The processor calculates the liquid level depth corresponding to the current pressure according to the current pressure value, which solves the problem of discovering that the liquid in the container is exhausted, and solves the problem that it is difficult to discover or discover late after the pipeline or container connecting the container leaks or the liquid in the container is stolen. During the cooperation period between the two parties, Party A supplies liquid products to Party B's container. If a third party wants to cooperate with Party B, it will inevitably add liquid to the container. At this time, Party A will receive a telephone notification in time through this device to protect its legitimate rights and interests or discover its own problems through relevant actions to improve its competitiveness and solve the problem of unauthorized liquid filling. Before using the Internet of Things monitoring device, the box cover 9 needs to be connected to the placement box 2 through a connecting mechanism. The details are as follows;In the initial state, the controller 12 controls the electromagnet 32 ​​to be energized, and the button battery 29 provides power for the electromagnet 32. The card block 34 is made of iron material. When the electromagnet 32 ​​is energized, the magnetic force attracts the card block 34. The rebound force of the spring 33 is less than the suction force brought by the electromagnet 32 ​​to the card block 34. Therefore, the spring 33 is compressed at this time and the card block 34 is adsorbed and retreated. Then, the cylinders 25 at the four corners of the box cover 9 are inserted into the column grooves 24 of the rectangular block 23. When the cylinder 25 is completely inserted into the column grooves 24 and cannot be lowered any further, At this time, the card slot 27 is just located at the position of the card block 34, and then the controller 12 controls the electromagnet 32 ​​to cut off the electromagnetic attraction, and the spring 33 is reset at this time to push the card block 34 out of the empty slot 31 and into the interior of the card slot 27, which is conducive to completing the connection between the placement box 2 and the box cover 9 by fixing the cylinder 25. When the placement box 2 needs to repair the internal circuit board 10 or other electrical components, the electromagnet 32 ​​is energized again, and then the card block 34 leaves the card slot 27 under the action of the magnetic attraction. At this time, the handle 26 pulls the cylinder 25, and then the cylinder 25 leaves the inside of the rectangular block 23, which is conducive to completing the separation of the placement box 2 and the box cover 9, and is convenient for repairing the inside of the placement box 2. Through the moisture-proof mechanism, the desiccant is placed inside the storage box 11 before the box cover 9 is connected to the placement box 2. The desiccant is conducive to preventing moisture from being generated inside the placement box 2. When the humidity sensor 14 detects that the humidity inside the placement box 2 is too high, it will send a desiccant notification to the user through the Internet of Things platform. When the temperature sensor senses that the temperature is too high, it will promptly notify the user by phone to confirm whether there is a fire. When the box cover 9 is connected to the placement box 2, the pressure plate 19 on the inside of the box cover 9 enters the inside of the groove 17. The diameter of the pressure plate 19 is one-third of the groove 17. When the pressure plate 19 enters the groove 17, the pressure plate 19 presses the airbag 18 and then a part of the airbag 18 is squeezed out of the groove 17. The squeezed part is conducive to filling the gap at the connection between the box cover 9 and the placement box 2, which is conducive to preventing dust or moisture from entering through the gap. ;
