Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0044] In one embodiment, such as Figure 1 As shown, an environmental temperature and humidity acquisition device is provided, including a first monitoring device, a second monitoring device, a first wireless communication module, and a wireless gateway. The first monitoring device includes a temperature and humidity monitoring device and a wired communication module; the temperature and humidity monitoring device of the first monitoring device is connected to the wired communication module; the wired communication module is connected to the first wireless communication module. The second monitoring device includes a temperature and humidity monitoring device and a second wireless communication module; the temperature and humidity monitoring device of the second monitoring device is connected to the second wireless communication module; the second wireless communication module is wirelessly connected to the first wireless communication module.

In this embodiment, the wired communication module and the first wireless communication module are wired together. It should be noted that... Figure 1 Solid lines indicate wired connections, while dashed lines indicate wireless connections.

[0045] Optionally, the wired communication module in this embodiment can be a communication line or other communication equipment.

[0046] Optionally, in this embodiment, the first monitoring device is a wired temperature and humidity acquisition device. After the temperature and humidity monitoring device acquires the environmental temperature and humidity information, it sends it to the wired communication module via wired communication. The wired communication module then transmits the temperature and humidity information acquired by the first monitoring device to the first wireless communication module via wired communication.

[0047] Optionally, in this embodiment, the second monitoring device is a wireless temperature and humidity acquisition device. After acquiring the temperature and humidity information, the temperature and humidity monitoring device sends the temperature and humidity information to the first wireless communication module through the second wireless communication module.

[0048] Optionally, in this embodiment, the first wireless communication module sends the temperature and humidity information collected by the first and second monitoring devices to the wireless gateway, which then sends the temperature and humidity information to the remote control system. The remote control system can determine whether the current environment is suitable for tobacco product production based on the temperature and humidity information, and can also control relevant equipment for tobacco production based on the temperature and humidity information, such as adjusting the ambient temperature or humidity.

[0049] Optionally, in this embodiment, the first wireless communication module may be a LoRa module, which may be an SX1278 wireless transceiver module based on the Semtech SX1278 chip.

[0050] Optionally, in this embodiment, the wireless gateway can be a LoRa gateway module. The LoRa gateway module can be a gateway with model number XZ-DSG1.

[0051] Optionally, in this embodiment, the remote control system can be a remote monitoring system developed based on the THINGWORX platform.

[0052] In this embodiment, temperature and humidity data in the tobacco production environment can be collected using a first monitoring device and a second monitoring device. The first monitoring device can be applied to environments with complex conditions and weak wireless signal strength. The temperature and humidity monitoring device transmits the collected temperature and humidity information to a wired communication module via wired communication. The wired communication module then transmits the collected temperature and humidity information from the first monitoring device to a first wireless communication module via wired communication. The second monitoring device can be applied to environments with strong wireless signal strength. Based on the second wireless communication module, it transmits the collected temperature and humidity information to the first wireless communication module via wireless communication. The first wireless communication module then transmits the temperature and humidity information collected by the first and second monitoring devices to a remote control system via a wireless gateway. Based on the first and second monitoring devices, normal collection and timely transmission of temperature and humidity information in environments of varying complexity can be achieved. This increases the flexibility of deploying temperature and humidity monitoring devices, reduces wiring complexity and maintenance difficulty, and provides a good technical foundation for intelligent and timely sensing in tobacco production.

[0053] In one embodiment, to increase the practicality of the first monitoring device and the second monitoring device, such as Figure 2 The temperature and humidity monitoring device includes a device body and a temperature and humidity sensor 3. The device body includes a housing 1 and a microcontroller installed inside the housing 1. The temperature and humidity sensor 3 is mounted on a mounting plate 2, which is detachably connected to the housing 1 or the tobacco production equipment. The outer side of the housing 1 has one or more fixing plates 11, each with a strip-shaped fixing hole 12. The housing 1 is mounted on the fixing plate 11. When installing the device body of the monitoring device, bolts are passed through the strip-shaped fixing holes 12 to press the fixing plate 11, thereby serving to mount the device body. The microcontroller is connected to the temperature and humidity sensor 3. Optionally, in this embodiment, the fixing plate 11 and the housing 1 can be integrally formed, or they can be welded or bonded together.

[0054] In this embodiment, the temperature and humidity sensor 3 is mounted on the mounting plate 2. The mounting plate 2 is detachably connected to the housing 1, so that the mounting plate 2 can be fixedly installed with the housing 1 to form an integrated temperature and humidity monitoring device. Alternatively, it can be a separate connection. For example, when monitoring the temperature and humidity inside tobacco production equipment, the temperature and humidity sensor 3 can be installed inside the tobacco production equipment. To avoid the housing 1 occupying internal space and to avoid the microcontroller inside the housing 1 affecting its service life due to excessive temperature or humidity, the housing 1 can be installed outside the tobacco production equipment. This achieves a unique design for the temperature and humidity monitoring device, allowing for flexible selection of the assembly method between the temperature and humidity sensor 3 and the housing 1 according to different application environments. It can be a separate combination or an integrated combination.

[0055] It should be noted that, as Figure 2 As shown, the outer side of the housing 1 also has an interface, through which the microcontroller connects to a wired communication module or a wireless communication module. If the environment has weak wireless signal strength, a wired communication module can be connected, forming the first monitoring device. If the environment has strong wireless signal strength, to reduce wiring difficulty, a wireless communication module can be connected via the interface, forming the second monitoring device. The microcontroller's function is to process the temperature and humidity signals collected by the temperature and humidity sensor 3 (the processing method can be implemented using existing technology and will not be elaborated here), obtain the temperature and humidity information, and then upload it to the remote control system.

[0056] In one embodiment, such as Figure 3 , Figure 4 As shown, a fixing post 4 is fixedly mounted on the circuit board of the temperature and humidity sensor 3. The fixing post 4 has an internal threaded hole, and the mounting plate 2 has a through hole corresponding to the internal threaded hole. The fixing post 4 is fixed to the mounting plate 2 by the first bolt 21.

[0057] In this embodiment, the design of the fixing column 4 enables the combined installation of the temperature and humidity sensor 3 and the mounting plate 2. Furthermore, the design of the fixing column 4 ensures that after the temperature and humidity sensor 3 is installed on the mounting plate 2, the fixing column 4 acts as an isolation, leaving a gap between the temperature and humidity sensor 3 and the mounting plate 2, thereby increasing the accuracy of temperature and humidity monitoring.

[0058] In one embodiment, such as Figure 5As shown, the outer plate of the housing 1 has a recessed platform for mounting the temperature and humidity sensor 3 and the mounting plate 2. The temperature and humidity sensor 3 is mounted on the side of the mounting plate 2 adjacent to the recessed platform. The mounting plate 2 is detachably connected to the outer plate of the housing 1 or the tobacco production equipment by a second bolt 22. Based on the structural design of this embodiment, the temperature and humidity sensor 3 is embedded (embedded in the recessed platform) in the housing 1, making the outer surface of the housing 1 flatter and more aesthetically pleasing, and also preventing the temperature and humidity sensor 3 from being exposed and easily damaged.

[0059] In one embodiment, such as Figure 6 As shown, the temperature and humidity sensor 3 is connected to the microcontroller via a connecting cable 5. An extension cable 51 is also provided in the middle of the connecting cable 5 to extend its length. The outer plate of the housing 1 also has a cable groove 13 for placing the connecting cable 5. Optionally, the extension cable can be a spiral-shaped flexible connecting cable, or it can be a bundled cable harness.

[0060] Optional, such as Figure 6 As shown, the outer panel has a storage slot 14 for placing the extension cable 51.

[0061] In this embodiment, the outer panel of the housing is also provided with a wire groove 13 and a storage groove 14 for placing the extension cable 51, so as to avoid the connecting cable 5 being exposed to the outside, which is not only unsightly, but also easy to damage the connecting cable 5. Based on the extension cable 51, when the temperature and humidity sensor 3 is installed separately from the housing 1, the temperature and humidity sensor 3 can be installed at a farther position on the housing 1, and can be used in more complex environments.

[0062] In one embodiment, the temperature and humidity sensor 3 is a DHT11 type digital temperature and humidity sensor 3.

[0063] Optionally, in this embodiment, pin 2 of the temperature and humidity sensor 3 (i.e. Figure 7 Pin 2 of the sensor is connected to the microcontroller; pin 1 of the temperature and humidity sensor 3 is connected to the power supply; pin 4 of the temperature and humidity sensor 3 is grounded.

[0064] Optionally, in this embodiment, a pull-up resistor is also connected to pin 2 of the temperature and humidity sensor 3 on the communication line between the sensor and the microcontroller. One end of the pull-up resistor is connected to the communication line, and the other end is connected to the power supply (i.e., Figure 7 (VDD end in the middle).

[0065] In one embodiment, a tobacco production apparatus is provided, wherein the tobacco production apparatus includes the environmental temperature and humidity acquisition device provided in any of the above embodiments. The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; however, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification.

[0066] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
