Description

Technical Field

[0001] This application relates to the field of wireless sensor monitoring technology for temperature and humidity in tobacco boxes, and particularly to a wireless distributed detection system for monitoring temperature and humidity in tobacco boxes using wireless sensors. Background Technology

[0002] Moisture content detection in tobacco warehouses is a key parameter for controlling the temperature and humidity environment during tobacco storage. At this stage, the moisture content of tobacco leaves needs to be maintained within a stable "safe range," typically 12%-15%. Environmental factors primarily affect the following: In high humidity, tobacco leaves absorb moisture from the air, increasing their moisture content. When the moisture content exceeds 15%, mold will multiply rapidly, causing the tobacco leaves to rot, produce a musty smell, and become completely unusable. Excessive fermentation leads to excessively dark color or even carbonization. Humid environments easily breed pests such as tobacco beetles, while in low humidity environments, tobacco leaves release moisture into the dry air. When the moisture content is below 10%, the tobacco leaves become brittle, lose elasticity, and are easily broken during handling and processing, resulting in a significant decrease in yield. Excessive dryness causes the loss of volatile aroma compounds. High temperatures accelerate the process of moisture absorption or release, while also accelerating changes in chemical composition and the activity of insects and mold.

[0003] However, it is difficult to flexibly adjust the temperature and humidity monitoring locations in the smoke box, and temperature and humidity cannot be used together or in separate zones, which limits its application and affects the flexibility of monitoring. Summary of the Invention

[0004] This application is made in view of the above-mentioned problems, and its purpose is to provide a wireless distributed detection system for monitoring the temperature and humidity of a smoke box using a wireless sensor, so as to solve the problems mentioned in the background art. To achieve the above objectives, the present invention provides the following technical solution: a wireless distributed detection system for monitoring the temperature and humidity of a cigarette box using a wireless sensor, comprising a collection plate and a guide rod. A fixed plate is provided on one side of the collection plate, and a threaded rod is installed inside the fixed plate. The guide rod is slidably disposed inside the fixed plate. Built-in slots are provided on both sides of the inside of the collection plate. A humidity sensor body is installed inside one set of the built-in slots, and a humidity probe is installed at the bottom of the humidity sensor body. A mesh cover is fitted onto the outside of the humidity probe. A temperature sensor body is provided on one side of the inside of the collection plate, and a cleaning brush is arranged in a ring inside the built-in slots.

[0005] Furthermore, the fixing plate is provided in two sets, and the two sets of fixing plates are distributed in a one-to-one correspondence with the threaded rod and the guide rod.

[0006] Furthermore, another set of the built-in slots contains a temperature sensor body, and a temperature probe is installed at the bottom of the temperature sensor body.

[0007] Furthermore, a pad is provided on one outer surface of both the temperature sensor body and the humidity sensor body in an arc shape.

[0008] Furthermore, a drive assembly for auxiliary driving is provided at the bottom center of the assembly plate, and the drive assembly includes a servo motor, a drive gear and a rack. The output end of the servo motor is equipped with a drive gear through a drive shaft, and a rack is meshed on the outer surface of the drive gear.

[0009] Furthermore, the rack is provided in two sets, and each end of the rack is equipped with an adjustment component for auxiliary positioning.

[0010] Furthermore, the adjustment assembly includes a fixed outer frame, a pressure sensor, and a positioning plate, with the positioning plate slidably installed inside the fixed outer frame, and a pressure sensor provided on one side of the positioning plate.

[0011] Furthermore, the fixed outer frame is fixedly installed on one side of the outer surface of the assembly plate, and the fixed outer frame has a hollow structure, and the fixed outer frame is distributed in a one-to-one correspondence with the positioning plate.

[0012] Furthermore, the output terminals of the temperature probe and humidity probe are electrically connected to a data acquisition module, the output terminal of the data acquisition module is electrically connected to a chip module, and the output terminal of the chip module is electrically connected to a storage module.

[0013] Furthermore, the output of the storage module is electrically connected to a classification module, the output of the classification module is electrically connected to a SWARM wireless communication module, and the output of the SWARM wireless communication module is electrically connected to a terminal platform module.

[0014] Compared with the prior art, the present invention has the following beneficial effects: the servo motor in the drive assembly drives the drive gear and rack to mesh and transmit power, which can drive the adjustment assembly to move precisely. In conjunction with the pressure sensor in the adjustment assembly, the contact pressure between the positioning plate and the smoke box is sensed in real time, which is convenient for adapting to the smoke box environment under different monitoring conditions and reducing the limitations of use. The temperature probe and humidity probe can move in the axial direction or downward through the design of the fixing plate, threaded rod and guide rod, which is convenient for the temperature probe and humidity probe to adjust their positions as needed for synchronous or independent monitoring. At the same time, the arc-shaped pad made of rubber can buffer and protect the temperature sensor body and humidity sensor body, improving the installation stability and service life of the device.

[0015] The temperature probe at the bottom of the temperature sensor body and the humidity probe at the bottom of the humidity sensor body can simultaneously collect temperature and humidity data inside the tobacco box. The cleaning brush with a ring inside the built-in groove can clean the surface of the end area when the threaded rod is rotated to drive the temperature and humidity probes axially, avoiding impurities from affecting the monitoring accuracy. At the same time, the mesh cover design can protect the humidity probe when it is inserted into the tobacco box for humidity monitoring, avoiding unnecessary scratches and affecting its service life. In addition, the mesh design of the mesh cover can block large tobacco leaves from entering without blocking moisture, ensuring the humidity monitoring effect. The acquisition module quickly collects the probe data and transmits it to the chip module. Together with the storage module, the data is retained, providing a reliable basis for subsequent analysis and greatly improving monitoring efficiency and data accuracy.

[0016] After classifying and organizing the temperature and humidity data in the storage module, the classification module transmits the data to the terminal platform module via the SWARM wireless communication module. This enables distributed data aggregation from multiple monitoring points without complex wiring, meeting the monitoring needs of large-scale cigarette box storage scenarios. At the same time, the terminal platform module can receive data in real time, allowing staff to remotely monitor the temperature and humidity status of the cigarette box, promptly handle abnormal situations, reduce manual inspection costs, and improve management efficiency.

[0025] Terminology explanation: such as Figures 1 to 6As shown, a wireless distributed detection system for monitoring the temperature and humidity of a cigarette box using a wireless sensor includes a collection plate 1, a temperature sensor body 2, a humidity sensor body 3, an internal groove 4, a pad 5, a fixing plate 6, a threaded rod 7, a guide rod 8, a cleaning brush 9, a temperature probe 10, a humidity probe 11, a mesh cover 12, an adjustment assembly 13, a fixed outer frame 1301, a pressure sensor 1302, a positioning plate 1303, a drive assembly 14, a servo motor 1401, a drive gear 1402, a rack 1403, a data acquisition module 15, and a core. The assembly plate 1 includes a chip module 16, a storage module 17, a classification module 18, a SWARM wireless communication module 19, and a terminal platform module 20. A fixing plate 6 is provided on one side of the assembly plate 1, and a threaded rod 7 is installed internally on the fixing plate 6. A guide rod 8 is slidably disposed inside the fixing plate 6. Both sides of the assembly plate 1 have internal slots 4. A humidity sensor body 3 is installed inside one set of internal slots 4, and a humidity probe 11 is installed at the bottom of the humidity sensor body 3. A mesh cover 12 is fitted onto the outside of the humidity probe 11. A temperature sensor body 2 is installed on one side of the inner side of the composite board 1. The output ends of the temperature probe 10 and humidity probe 11 are electrically connected to the acquisition module 15, and the output end of the acquisition module 15 is electrically connected to the chip module 16. The output end of the chip module 16 is electrically connected to the storage module 17, the output end of the storage module 17 is electrically connected to the classification module 18, the output end of the classification module 18 is electrically connected to the SWARM wireless communication module 19, and the output end of the SWARM wireless communication module 19 is electrically connected to the terminal platform module 20. The acquisition module 15 quickly collects the probe data and transmits it to the chip module 16. In conjunction with the storage module 17, the data is retained to provide a reliable basis for subsequent analysis, which greatly improves the monitoring efficiency and data accuracy. After the classification module 18 classifies and organizes the temperature and humidity data in the storage module 17, it transmits the data to the terminal platform module 20 through the SWARM wireless communication module 19. Distributed data aggregation of multiple monitoring points can be achieved without complex wiring, which is suitable for the monitoring needs of large-scale cigarette box storage scenarios.Meanwhile, the terminal platform module 20 can receive data in real time, facilitating remote monitoring of the temperature and humidity status of the tobacco box by staff, timely handling of abnormal situations, reduction of manual inspection costs, and improvement of management efficiency. The internal groove 4 has a ring-shaped cleaning brush 9. The temperature probe 10 at the bottom of the temperature sensor body 2 and the humidity probe 11 at the bottom of the humidity sensor body 3 can simultaneously collect temperature and humidity data inside the tobacco box. The ring-shaped cleaning brush 9 inside the internal groove 4 can clean the end areas when the threaded rod 7 rotates, causing the temperature probe 10 and humidity probe 11 to move axially, preventing impurities from affecting monitoring accuracy. Simultaneously, the mesh cover 12 protects the humidity probe 11 when it is inserted into the tobacco box for humidity monitoring, preventing unnecessary scratches and extending its service life. Furthermore, the mesh design of the mesh cover 12 can block large tobacco leaves. The device does not block water vapor during entry, ensuring effective humidity monitoring. Two sets of fixing plates 6 are provided, with each set corresponding to a threaded rod 7 and a guide rod 8. The other set has a built-in groove 4 containing a temperature sensor body 2, with a temperature probe 10 installed at the bottom. A pad 5 is provided on one outer surface of both the temperature sensor body 2 and the humidity sensor body 3, and the pad 5 has an arc-shaped structure. The temperature probe 10 and humidity probe 11 can move axially or vertically along the threaded rod 7 through the design of the fixing plates 6, threaded rod 7, and guide rod 8, facilitating the adjustment of their positions for synchronous or independent monitoring. At the same time, the rubber-made arc-shaped pad 5 provides buffer protection for the temperature sensor body 2 and the humidity sensor body 3, improving the installation stability and service life of the device. A drive assembly 14 for auxiliary driving is provided at the bottom center of the assembly plate 1. The drive assembly 14 includes a servo motor 1401, a drive gear 1402, and a rack 1403. The output end of the servo motor 1401 is mounted with the drive gear 1402 via a drive shaft. The outer surface of the drive gear 1402 is meshed with the rack 1403. Two sets of racks 1403 are provided, and each end of the rack 1403 is equipped with an adjustment assembly 13 for auxiliary positioning. The adjustment assembly 13 includes a fixed outer frame 1301, a pressure sensor 1302, and a positioning plate 1303. The positioning plate 13 is slidably installed inside the fixed outer frame 1301. 03. A pressure sensor 1302 is provided on one side of the positioning plate 1303. The fixed outer frame 1301 is fixedly installed on the outer surface of one side of the assembly plate 1. The fixed outer frame 1301 has a hollow structure and is distributed one-to-one with the positioning plate 1303. The servo motor 1401 in the drive assembly 14 drives the drive gear 1402 to mesh with the rack 1403, which can drive the adjustment assembly 13 to move precisely. With the pressure sensor 1302 in the adjustment assembly 13, the contact pressure between the positioning plate 1303 and the smoke box is sensed in real time, which is convenient for adapting to the smoke box environment under different monitoring environments and reducing the limitations of use.Based on the above principle, the system foundation is first fixed by the fixing plate 6 on one side of the assembly plate 1. Tightening the threaded rod 7, in conjunction with the guiding action of the guide rod 8, drives the temperature sensor body 2 and the humidity sensor body 3 to move up and down axially, realizing the synchronous or independent adjustment of the monitoring positions of the temperature probe 10 and the humidity probe 11, adapting to the monitoring depth requirements of different smoke boxes. At the same time, the drive component 14 at the bottom center of the assembly plate 1 starts working. The servo motor 1401 outputs power to drive the drive gear 1402 to rotate through the drive shaft. Utilizing the meshing transmission between the drive gear 1402 and the two sets of racks 1403, the adjustment component 13 connected to the end of the rack 1403 is precisely displaced. During the displacement, the adjustment component 13 is slidably set in the fixed outer frame 1301. The positioning plate 1303 gradually adheres to the inner wall of the tobacco box. The pressure sensor 1302 senses the adhesion pressure in real time and feeds back a signal until the positioning plate 1303 reaches a stable adhesion state, completing the precise positioning of the system inside the tobacco box. This adapts to the monitoring environment of tobacco boxes of different specifications, reducing usage limitations. During this process, the arc-shaped pads 5 on one side of the outer surface of the temperature sensor body 2 and the humidity sensor body 3 play a buffering and protective role, improving the installation stability of the sensors and the overall service life of the device. After positioning, the temperature probe 10 at the bottom of the temperature sensor body 2 and the humidity probe 11 at the bottom of the humidity sensor body 3 are simultaneously inserted into the tobacco box to begin real-time collection of temperature and humidity data inside the tobacco box. The mesh cover 12 that is locked outside the humidity probe 11 can prevent impurities such as large tobacco leaves from entering. The sensor body is designed to allow water vapor to pass through without obstructing its flow, protecting the humidity probe 11 from scratches and extending its lifespan while ensuring humidity monitoring accuracy. If impurities adhere to the probe tip during monitoring, the sensor body can be moved axially again via the threaded rod 7, allowing the probe to pass through the annular cleaning brush 9 inside the built-in groove 4. The cleaning brush 9 cleans the surface of the probe tip area, preventing impurities from affecting subsequent monitoring accuracy. The temperature probe 10 and humidity probe 11 transmit the collected temperature and humidity signals to the acquisition module 15, which quickly collects various data and transmits them to the chip module 16. After preliminary processing, the chip module 16 transmits the data to the storage module 17 for storage, providing a reliable basis for subsequent data traceability and analysis. Data within the storage module 17 is transmitted to the classification module 18, which categorizes and organizes the data according to monitoring points, time, and other dimensions. The categorized temperature and humidity data is then wirelessly transmitted to the terminal platform module 20 via the SWARM wireless communication module 19. This eliminates the need for complex wiring, enabling distributed data aggregation from multiple monitoring points. The terminal platform module 20 receives the temperature and humidity data transmitted from each monitoring point in real time, allowing staff to remotely monitor the temperature and humidity status of all cigarette boxes. When the platform detects that the temperature and humidity data of a cigarette box exceeds a preset threshold, it will promptly issue an anomaly warning. Staff can quickly locate the abnormal cigarette box and take targeted measures, significantly reducing manual inspection costs and improving management efficiency in large-scale cigarette box storage scenarios.

Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
