Description

Technical Field

[0001] This utility model belongs to the field of sensor technology, specifically an assembly structure for an Internet of Things (IoT) sensor. Background Technology

[0002] Agricultural Internet of Things (IoT) refers to the Internet of Things that uses various instruments and meters to display data in real time or participate in automatic control processes. It can provide a scientific basis for precise agricultural regulation, achieving the goals of increasing yield, improving quality, regulating growth cycles, and enhancing economic benefits.

[0003] Agricultural IoT typically involves constructing a monitoring network of numerous sensor nodes. These sensors collect information to help farmers promptly identify and accurately pinpoint problems. This gradually shifts agriculture from a labor-intensive, machine-dependent production model to an information- and software-centric one, leading to the widespread use of automated, intelligent, and remotely controlled production equipment. Taking rural biogas as an example, sensors monitor biogas concentration in the environment in real time. When the concentration exceeds limits, a direct alarm is triggered or a related early warning system is activated, thus providing safety monitoring for the IoT and the entire agricultural system. Unlike sensors in other fields, sensors used in agricultural IoT operate unattended for extended periods. The durability of their assembly structure directly determines the maintenance and replacement cycle. Therefore, ensuring both excellent monitoring capabilities and a reliable assembly structure is a key technical challenge that needs to be addressed. Summary of the Invention

[0004] The technical problem to be solved by this invention is: how to ensure both good monitoring capabilities and a reliable assembly structure for toxic gas sensors in agricultural Internet of Things (IoT) applications.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution:

[0006] An assembly structure for an Internet of Things (IoT) sensor includes a protective shell, a top plate, claws, an airflow inlet, an airflow outlet, a control board, a columnar groove, a fan, an alarm, a detection probe, a grid, an LCD screen, a control panel, a vertical plate, a rotating plate, protruding teeth, a ring, and a top shell. The top plate is located on the upper side of the protective shell. Claws are fixed to the bottom of the top plate, and a groove matching the claws is provided on the upper side of the protective shell. The claws and grooves are fixed to each other. An airflow inlet and an airflow outlet are provided on the left and right sides of the top plate. The control board is secured inside the protective shell. A columnar groove is provided inside the protective shell, and a battery in the columnar groove powers the control board. A fan is fixedly installed at the airflow inlet, an alarm is fixedly installed inside the protective housing, and a detection probe is fixedly installed at the airflow outlet. The detection probe, alarm, and fan are each connected to the control board via cables. A grille is fixed on the upper side of the airflow outlet. An LCD screen and control panel are fixedly installed on the outer side of the protective housing. The LCD screen and control panel are also connected to the control board via cables. A vertical plate is located at the rear of the protective housing. The vertical plate has protruding teeth. A rotating plate is rotatably connected to the root of the vertical plate. The rotating plate also has other protruding teeth. A ring is provided on the protective housing, and a top shell is fixed on the top plate.

[0007] Preferably, an anode contact and a cathode contact are provided on both sides of the columnar groove, and the anode contact and the cathode contact form a circuit with the control board.

[0008] Preferably, the outer edge of the grille is circular, and there is an upwardly protruding cone in the middle of the grille, and the top of the grille is closed.

[0009] Preferably, the protective shell has a key and the control board has a hole, and when the control board is placed into the protective shell, the key and the hole are engaged.

[0010] Preferably, the protective shell includes a front shell, a rear shell, and a bottom shell, wherein the front shell and the rear shell are secured together to form a tubular body, which is secured to the upper side of the edge of the bottom shell.

[0011] Preferably, a rotating cover is provided on the bottom shell, and the columnar groove is retained inside the rotating cover.

[0012] Preferably, the control board communicates remotely with the IoT control system, uploading detection results from the detection probe and receiving control commands from the IoT control system.

[0013] Preferably, a power cord is used instead of the cylindrical slot and the battery, and the power cord is connected to a power source.

[0014] The protective shell serves as the external protection structure for the sensor. The top plate is fixed to the protective shell by clips, ensuring that the airflow inlet and outlet on the top plate are positioned above the inner cavity of the protective shell. The airflow inlet, the inner cavity of the protective shell, and the airflow outlet form an airflow channel. This airflow channel, driven by a fan, creates a unidirectional airflow. Detection probes (such as hydrogen sulfide sensors or ammonia sensors) react to the flowing toxic gases within this airflow channel, then send the reaction signal to the alarm for direct sounding or remote alarm activation. The control board controls and relays the above process; a battery within the columnar slot powers the control board. The grille protects the airflow outlet and detection probe. The LCD screen directly displays monitoring data from the control board, and the control panel allows input of control commands. Vertical plates, rotating plates, and protruding teeth clamp the entire sensor assembly structure in one location, while the annular body secures the entire sensor assembly structure in another location. The top shell protects the top plate.

[0015] In the above technical solution, the control board can be a conventional sensor control board, with options including Arduino series development boards, Raspberry Pi, STM32, etc. The detection probe can be a standard hydrogen sulfide sensor or an ammonia sensor. For hydrogen sulfide, an Alphasense H2S-A1 or Detcon TP-624C can be used; for ammonia, an Alphasense NH3-AF or a domestic Weisheng ME3-NH3 can be used. The alarm can be an electromagnetic active integrated buzzer, such as the Foshan Jingci 0905 buzzer. The detection probe, alarm, fan, etc., are electrically connected to the control board.

[0016] This invention discloses an assembly structure for an Internet of Things (IoT) sensor. This assembly structure conceals the core monitoring module within a protective shell and establishes a unidirectional airflow channel using the top inlet and outlet ports and a fan inside the protective shell; simultaneously, a built-in alarm is used for response. This assembly structure protects the monitoring, control, alarm, and power supply modules, ensuring stable monitoring functionality while maintaining a reliable assembly structure.
