Description

Technical Field

[0001] The present application relates to the technical field of tobacco detection, and in particular to a moisture content detection device and a tobacco stack environmental parameter detection system. Background Art

[0002] Tobacco typically needs to be stored in warehouses for at least three years to allow for natural aging before it can be used in production. For large tobacco stacks, the weight of each stack can range from several to tens of tons. During storage, the tobacco stack environment fluctuates, often leading to problems such as insect infestation and mold. Therefore, precise monitoring of parameters such as temperature and humidity, oxygen concentration, wrapper temperature, and / or tobacco moisture is essential.

[0003] However, current methods for monitoring tobacco stack environmental parameters rely primarily on manual testing, which is labor-intensive and complex. Data recording errors can lead to confusion in guiding oxygen reduction and pest control, resulting in a waste of resources. Furthermore, the nitrogen filling and oxygen reduction process in tobacco factories also requires personnel to enter the low-oxygen work area to record data, which presents certain safety risks.

[0031] It will be apparent to those skilled in the art that various modifications and variations can be made in this application without departing from the spirit or scope of this application. Therefore, this application is intended to cover modifications and variations of this application that fall within the scope of the corresponding claims (technical solutions claimed for protection) and their equivalents. It should be noted that the embodiments provided in the examples of this application can be combined with each other without contradiction.

[0032] Before describing the technical solutions provided by the embodiments of the present application, in order to facilitate understanding of the embodiments of the present application, the present application first specifically describes the problems existing in the related art:

[0033] Tobacco typically needs to be stored in warehouses for at least three years to allow for natural aging before it can be used in production. For large tobacco stacks, the weight of each stack can range from several to tens of tons. During storage, the tobacco stack environment fluctuates, often leading to problems such as insect infestation and mold. Therefore, precise monitoring of parameters such as temperature and humidity, oxygen concentration, wrapper temperature, and / or tobacco moisture is essential.

[0034] However, current methods for monitoring tobacco stack environmental parameters rely primarily on manual testing, which is labor-intensive and complex. Data recording errors can lead to confusion in guiding oxygen reduction and pest control, resulting in a waste of resources. Furthermore, the nitrogen filling and oxygen reduction process in tobacco factories requires personnel to enter low-oxygen work areas to record data, posing a safety risk. Furthermore, currently used temperature and humidity sensors and oxygen content sensors are mostly independent products with low integration levels. Each sensor needs to be individually installed, which is a significant workload.

[0035] In view of the above research findings of the inventors, the embodiments of the present application provide a wireless temperature, humidity and oxygen content detection device and a tobacco stack environmental parameter detection system, which can solve at least one of the above technical problems existing in the related art.

[0036] The following first introduces the wireless temperature, humidity and oxygen content detection device provided in the embodiment of the present application.

[0037] In some embodiments, the wireless temperature, humidity, and oxygen content detection device can be placed in an airtight tent, where one or more tobacco piles are placed. The wireless temperature, humidity, and oxygen content detection device can be placed near the tobacco piles. For example, the wireless temperature, humidity, and oxygen content detection device can be placed on the tobacco piles, with each tobacco pile being equipped with one or more wireless temperature, humidity, and oxygen content detection devices.

[0038] Figure 1 A circuit diagram of a wireless temperature, humidity and oxygen content detection device provided in an embodiment of the present application. Figure 1 As shown, the wireless temperature, humidity, and oxygen content detection device 10 may include a first processor 110, a temperature and humidity sensor 120, an oxygen sensor 130, a first signal processing circuit 140, and a first wireless communication module 150. The temperature and humidity sensor 120 may be electrically connected to the first processor 110 and may be configured to collect temperature and humidity data around the tobacco stack and transmit the temperature and humidity data around the tobacco stack to the first processor 110. Specifically, the temperature and humidity sensor 120 may be configured to generate and transmit the temperature and humidity data around the tobacco stack to the first processor 110 in response to the temperature and humidity around the tobacco stack. The temperature data collected by the temperature and humidity sensor 120 reflects the temperature around the tobacco stack, and the humidity data collected by the temperature and humidity sensor 120 reflects the humidity around the tobacco stack.

[0039] The oxygen sensor 130 can be used to detect the oxygen content, or oxygen concentration, around the tobacco stack. Specifically, the oxygen sensor 130 can output a current signal in response to the oxygen content around the tobacco stack. Typically, the current signal output by the oxygen sensor 130 has a relatively low value, such as a microampere level. To improve the accuracy of oxygen content detection, the wireless temperature, humidity, and oxygen content detection device 10 is equipped with a first signal processing circuit 140.

[0040] like Figure 1 As shown, the first signal processing circuit 140 is electrically connected between the oxygen sensor 130 and the first processor 110. The first signal processing circuit 140 can be configured to receive the current signal output by the oxygen sensor 130 and convert the current signal into a voltage signal. After converting the current signal into a voltage signal, the first signal processing circuit 140 can also be configured to amplify the voltage signal and perform analog-to-digital conversion on the amplified voltage signal, i.e., convert the amplified voltage signal into a digital signal. The first signal processing circuit 140 then transmits the digital signal to the first processor 110. The first processor 110 can read the digital signal output by the first signal processing circuit 140, such as a discrete combination of 0s and 1s, to obtain oxygen content data around the tobacco stack.

[0041] The first wireless communication module 150 can be electrically connected to the first processor 110, and the first wireless communication module 150 can communicate with the first processor 110. The first wireless communication module 150 can be used to receive temperature data around the tobacco stack, humidity data around the tobacco stack, and oxygen content data around the tobacco stack sent by the first processor 110, and wirelessly transmit the temperature data around the tobacco stack, humidity data around the tobacco stack, and oxygen content data around the tobacco stack to the gateway device, and transmit the temperature data around the tobacco stack, humidity data around the tobacco stack, and oxygen content data around the tobacco stack to the host computer through the gateway device, thereby realizing automatic detection of temperature, humidity, and oxygen content around the tobacco stack.

[0042] The wireless temperature, humidity and oxygen content detection device provided in the embodiments of the present application can, on the one hand, realize automatic detection of temperature, humidity and oxygen content around the tobacco stack, reduce the workload of detection personnel and improve detection efficiency; on the other hand, the wireless temperature, humidity and oxygen content detection device can wirelessly transmit the temperature data, humidity data and oxygen content data around the tobacco stack to the gateway device, and then transmit it to the host computer through the gateway device, thereby realizing automatic uploading and recording of data, reducing the error rate of data recording and improving detection accuracy; on the other hand, during the nitrogen filling and oxygen reduction process, automatic detection of temperature, humidity and oxygen content around the tobacco stack can be realized without personnel entering the low-oxygen working area, which can improve detection safety and reduce detection risks; on the other hand, the wireless temperature, humidity and oxygen content detection device adopts wireless communication, reduces a large amount of wiring and is easy to arrange; in addition, the wireless temperature, humidity and oxygen content detection device integrates temperature and humidity sensors and oxygen sensors, improves the integration of the detection device, and further reduces the layout workload.

[0043] Generally speaking, tobacco stack environmental parameters require long-term monitoring. However, the inventors of this application discovered that currently used monitoring products often have a battery life of less than three months, failing to meet the actual needs of the tobacco industry. Furthermore, airtight tents are generally not allowed to be opened after nitrogen filling and oxygen reduction, making it impossible to replace batteries or monitoring products in a timely manner, resulting in a gap in testing.

[0044] In view of this, according to some embodiments of the present application, the first processor 110 may optionally be a low-power chip. For example, the first processor 110 may be a low-power chip whose output current in low-power mode is less than a preset threshold. This can improve the battery life of the wireless temperature, humidity, and oxygen content detection device, meeting the practical needs of tobacco stack environmental parameter detection.

[0045] In some specific embodiments, the first processor 110 may optionally use an ultra-low-power STM32L0 series chip, i.e., an STM32L0 series single-chip microcomputer. The STM32L0 series chip integrates a high-performance Arm Cortex-M0+ 32-bit RISC core with an operating frequency of 32 MHz, which can increase the battery life of the product while meeting the processing speed.

[0046] The first processor 110 has multiple pins. For example, the debug pins of the first processor 110 can be connected to a debug module, which can be used to debug the first processor 110. In addition, the first processor 110 can also be connected to a first reset module, which can be used to reset the first processor 110.

[0047] Figure 2 This is a circuit connection diagram of the first signal processing circuit in the wireless temperature, humidity and oxygen content detection device provided in the embodiment of the present application. Figure 2 As shown, according to some embodiments of the present application, optionally, the first signal processing circuit 140 may include a voltage divider module 141 , at least one operational amplifier module 142 and an analog-to-digital conversion module 143 . Figure 2 The following description takes as an example that the first signal processing circuit 140 includes two operational amplification modules 142 , namely a first operational amplification module 1421 and a second operational amplification module 1422 .

[0048] like Figure 2 As shown, voltage divider module 141 is electrically connected between oxygen sensor 130 and at least one operational amplifier module 142. Voltage divider module 141 can be used to convert a current signal into a voltage signal. A first end of voltage divider module 141 is electrically connected to the output end of oxygen sensor 130, and a second end of voltage divider module 141 is grounded. After the current signal flows through voltage divider module 141, voltage divider module 141 generates a voltage, thereby converting the current signal into a voltage signal. Voltage divider module 141 can be a voltage divider resistor. The resistance value of the voltage divider resistor can be flexibly adjusted according to actual conditions, and this application does not limit this.

[0049] After the voltage divider module 141 converts the current signal into a voltage signal, the voltage value of the voltage signal is also small, such as only at the millivolt level. At least one operational amplifier module 142 can be electrically connected to the voltage divider module 141, and at least one operational amplifier module 142 can be used to amplify the voltage signal to obtain an amplified voltage signal. Figure 2As shown, after the voltage signal is amplified by the first operational amplifier module 1421 and the second operational amplifier module 1422, a voltage signal with a relatively large voltage value, such as a voltage signal of 0.4V-2V, can be obtained. The amplification factors of the first operational amplifier module 1421 and the second operational amplifier module 1422 can be flexibly adjusted according to actual conditions, and this application does not limit this.

[0050] Each operational amplifier module 142 may include an operational amplifier and an adjustment resistor. The adjustment resistor is electrically connected to the operational amplifier, and the amplification factor of the operational amplifier module 142 can be adjusted by adjusting the resistance value of the adjustment resistor.

[0051] like Figure 2 As shown, the analog-to-digital conversion module 143 is electrically connected between at least one operational amplifier module 142 and the first processor 110. The analog-to-digital conversion module 143 can be used to convert the amplified voltage signal into a digital signal and transmit the digital signal to the first processor 110. In some examples, the analog-to-digital conversion module 143 can be an analog-to-digital conversion (AD) chip. The clock pin, enable pin, and data output pin of the AD chip can be electrically connected to different I / O pins of the first processor 110, respectively. The AD chip can be used to perform analog-to-digital conversion on the amplified voltage signal output by the operational amplifier module 142, convert the amplified voltage signal into a digital signal, and transmit the digital signal to the first processor 110. The first processor 110 can be used to read the digital signal output by the AD chip to obtain oxygen content data around the tobacco stack.

[0052] Considering the complex detection environment during tobacco stack oxygen detection, in some embodiments, the oxygen sensor 130 may be equipped with an oxygen detection probe. For example, in some examples, the oxygen sensor 130 may be an O2-C2 oxygen sensor.

[0053] In this way, since the oxygen detection probe has strong anti-interference ability, it can accurately measure the oxygen content around the tobacco stack, and the calibration cycle is long, which can reduce the calibration cost.

[0054] Figure 3 This is a circuit connection diagram of the temperature and humidity sensor in the wireless temperature, humidity and oxygen content detection device provided in the embodiment of the present application. Figure 3As shown, in some embodiments, the temperature and humidity sensor 120 can optionally use a high-precision GXHT30C temperature and humidity module. The temperature and humidity sensor 120 can be powered by a 3.3V power supply and transmit data with the first processor 110 via an Inter-Integrated Circuit (I2C) communication method. I2C communication only requires two signal lines, one data line (SDA) and one clock line (SCL). This simplified cable requirement reduces complexity.

[0055] Combine Figure 1 and Figure 3 As shown, in some embodiments, the temperature and humidity sensor 120 is provided with a clock signal output terminal THSCL and a data signal output terminal THSDA. The clock signal output terminal THSCL of the temperature and humidity sensor 120 is electrically connected to the clock signal input terminal of the first processor 110, and the data signal output terminal THSDA of the temperature and humidity sensor 120 is electrically connected to the data signal input terminal of the first processor 110. The temperature and humidity sensor 120 and the first processor 110 communicate via I2C, and the temperature and humidity sensor 120 can transmit the collected temperature and humidity data around the tobacco stack to the first processor 110.

[0056] like Figure 3 As shown, the clock signal output terminal THSCL of the temperature and humidity sensor 120 may be connected to a first pull-up resistor R38 , and the data signal output terminal THSDA of the temperature and humidity sensor 120 may be connected to a second pull-up resistor R39 .

[0057] In some embodiments, optionally, the first wireless communication module 150 may include a LoRa wireless communication module, which can realize wireless data transmission over a longer distance. LoRa (Long Range) wireless communication, for example, can realize wireless communication of several kilometers, and the LoRa wireless communication module can be battery-powered and can operate in low-power mode, thereby further extending the service life and endurance of the wireless temperature, humidity and oxygen content detection device, and meeting the actual use requirements of tobacco stack environmental parameter detection. In addition, LoRa wireless communication enhances anti-interference capability through technologies such as spread spectrum modulation and frequency hopping, and is suitable for working in complex channel environments.

[0058] The first wireless communication module 150 can communicate with the first processor 110 via a serial peripheral interface (SPI) communication method.

[0059] There are four main pins that can be used for SPI communication:

[0060] MOSI (Master Out Slave In): The master device sends data to the slave device.

[0061] MISO (Master In Slave Out): The slave device sends data to the master device.

[0062] SCK (Serial Clock): A clock signal generated by the master device, used to synchronize data transmission.

[0063] SS (NSS, CS): The master device selects the slave device, and the master device specifies to communicate with a certain slave device.

[0064] SPI communication typically has a high transmission rate, making it suitable for fast transmission of large amounts of data. Furthermore, it requires a simple pinout, typically requiring only four main signal lines, making it easy to connect to the hardware.

[0065] The first wireless communication module 150 may further be provided with a reset pin, which may be electrically connected to the first processor 110 .

[0066] The inventors of this application have further discovered that current temperature, humidity, and oxygen sensors are mostly powered by lithium batteries. However, tobacco is flammable, so when powered by lithium batteries, there is a risk of battery spontaneous combustion and tobacco burning. In view of this, in some embodiments of this application, the first processor 110 uses a low-power chip, such as the STM32L0 series chip, and uses a 3.6V dry cell battery to power the wireless temperature, humidity, and oxygen content detection device, thereby reducing the risk of battery spontaneous combustion and tobacco burning.

[0067] Figure 4 Another circuit diagram of the wireless temperature, humidity and oxygen content detection device provided in the embodiment of the present application. Figure 4 As shown, in some specific embodiments, optionally, the wireless temperature, humidity and oxygen content detection device 10 may further include a first power supply 160 and a first power supply chip 170. The first power supply 160 may be a 3.6V dry cell battery.

[0068] The first power chip 170 can be electrically connected to the first power supply 160. Specifically, the input end of the first power chip 170 can be electrically connected to the first power supply 160, and the output end of the first power chip 170 can be electrically connected to the first processor 110, the temperature and humidity sensor 120, the oxygen sensor 130 and the first wireless communication module 150. The first power chip 170 can be used to convert the 3.6V electrical signal output by the first power supply into an electrical signal of a target voltage value, and power the first processor 110, the temperature and humidity sensor 120, the oxygen sensor 130 and the first wireless communication module 150 through the electrical signal of the target voltage value. The target voltage value can be flexibly adjusted according to actual conditions, and this application does not limit this. For example, in some examples, the target voltage value can be 3.3V.

[0069] In this way, the embodiment of the present application uses a 3.6V dry battery to power the wireless temperature, humidity and oxygen content detection device, which can reduce the risk of battery spontaneous combustion and tobacco combustion.

[0070] According to some embodiments of the present application, optionally, the wireless temperature, humidity and oxygen content detection device 10 may also be provided with a first shell (not shown in the figure), and the first shell is provided with a vent. The material of the first shell and the number of vents can be flexibly adjusted according to actual conditions, and this application does not limit this. The first processor 110, the temperature and humidity sensor 120, the oxygen sensor 130, the first signal processing circuit 140 and the first wireless communication module 150 can all be located in the accommodation space formed by the first shell.

[0071] In this way, components such as the temperature and humidity sensor and the oxygen sensor are integrated into the first housing, making it easy to carry and deploy, reducing deployment workload. Furthermore, the first housing is provided with ventilation holes that allow air to circulate inside and outside the first housing, facilitating the temperature and humidity sensor and the oxygen sensor to detect temperature, humidity, and oxygen content data around the tobacco stack.

[0072] According to some embodiments of the present application, one or more tobacco stacks may be optionally placed in each airtight tent, and each tobacco stack may be equipped with at least one wireless temperature, humidity, and oxygen content detection device 10. Each wireless temperature, humidity, and oxygen content detection device 10 may be used to detect temperature data, humidity data, and oxygen content data around the corresponding tobacco stack, thereby improving the accuracy of environmental parameter detection of each tobacco stack.

[0073] Figure 5 This is a circuit diagram of an eight-position dial switch in the wireless temperature, humidity and oxygen content detection device provided in the embodiment of the present application. Figure 5 As shown, in order to distinguish the data uploaded by different wireless temperature, humidity and oxygen content detection devices, in some embodiments, the wireless temperature, humidity and oxygen content detection device may further include an eight-position dial switch 180. Figure 1 and Figure 5 As shown, the eight-position DIP switch 180 can be electrically connected to the first processor 110. The eight-position DIP switch 180 is provided with multiple switch buttons 180a, such as eight switch buttons 180a. Each switch button 180a can be set to an on state or an off state. The combination of multiple switch buttons 180a in different states is used to set the data upload time interval, communication address, communication channel and / or communication mode of the wireless temperature, humidity and oxygen content detection device.

[0074] Each switch button 180a can be set to "ON" or "OFF." A combination of multiple switch buttons 180a can represent a specific binary number. For example, a combination of two switch buttons 180a can represent binary numbers from 00 to 11, a combination of three switch buttons 180a can represent binary numbers from 000 to 111, and a combination of eight switch buttons 180a can represent binary numbers from 00000000 to 11111111.

[0075] The data upload interval is the time interval between two consecutive data uploads by the wireless temperature, humidity, and oxygen content detection device. The uploaded data may include temperature data, humidity data, and oxygen content data around the tobacco pile. The data upload interval can be flexibly adjusted based on actual conditions, such as 4 hours, 10 hours, or other time intervals, and this application does not limit this. The communication address, communication channel, and / or communication mode are used to distinguish data uploaded by different wireless temperature, humidity, and oxygen content detection devices.

[0076] like Figure 5As shown, in some specific embodiments, the eight-position dial switch 180 may optionally include a first eight-position dial switch 181 and a second eight-position dial switch 182. The first eight-position dial switch 181 can be used to set the data upload interval and communication channel of the wireless temperature, humidity, and oxygen content detection device. For example, the combination of the first four switch buttons 180a in the first eight-position dial switch 181 is used to set the data upload interval of the wireless temperature, humidity, and oxygen content detection device, i.e., a binary number ranging from 0000 to 1111. The combination of the last four switch buttons 180a in the first eight-position dial switch 181 is used to set the communication channel of the wireless temperature, humidity, and oxygen content detection device, i.e., a binary number ranging from 0000 to 1111. The second eight-position dial switch 182 can be used to set the communication address and communication mode of the wireless temperature, humidity, and oxygen content detection device. For example, the combination of the first six switch buttons 180a in the second eight-position dial switch 182 is used to set the communication address of the wireless temperature, humidity, and oxygen content detection device, i.e., a binary number ranging from 000000 to 111111. The combination of the last two switch buttons 180a in the second eight-position dial switch 182 is used to set the communication mode of the wireless temperature, humidity and oxygen content detection device, that is, the binary number is from 00 to 11.

[0077] When the first wireless communication module 150 wirelessly transmits the temperature data around the tobacco stack, the humidity data around the tobacco stack, and the oxygen content data around the tobacco stack to the gateway device, it can send a binary number representing the communication address, communication channel, and / or communication mode of the wireless temperature, humidity, and oxygen content detection device to the gateway device, thereby facilitating the gateway device and / or the host computer to distinguish the data uploaded by different wireless temperature, humidity, and oxygen content detection devices.

[0078] When detecting the environmental parameters of tobacco stacks, multiple gateway devices and multiple wireless temperature, humidity and oxygen content detection devices 10 can be set up to detect the temperature data, humidity data and oxygen content data around multiple tobacco stacks. Each gateway device can be associated with at least one wireless temperature, humidity and oxygen content detection device 10, that is, receive data uploaded by at least one wireless temperature, humidity and oxygen content detection device 10. All wireless temperature, humidity and oxygen content detection devices 10 associated with the same gateway device can use the same communication mode and the same communication channel, and different wireless temperature, humidity and oxygen content detection devices 10 associated with the same gateway device can use different communication addresses. That is, different communication modes and / or different communication channels can be used to distinguish different gateway devices, and different communication addresses can be used to distinguish different wireless temperature, humidity and oxygen content detection devices 10 associated with the same gateway device.

[0079] In this way, by setting the data upload time interval, communication address, communication channel and / or communication mode of the wireless temperature, humidity and oxygen content detection device through the eight-position dial switch, it is possible to automatically upload and record the environmental parameters of multiple tobacco stacks while distinguishing the data uploaded by different wireless temperature, humidity and oxygen content detection devices, thereby reducing the data recording error rate and improving the detection accuracy.

[0080] Based on the same or similar technical concept as the wireless temperature, humidity and oxygen content detection device provided in the above embodiment, the embodiment of the present application also provides a core temperature detection device. The core temperature detection device can be arranged inside the tobacco stack, such as at the center of the tobacco stack. The core temperature detection device can be used to detect the core temperature data inside the tobacco stack.

[0081] Figure 6 This is a circuit diagram of a core temperature detection device provided in an embodiment of the present application. Figure 6 As shown, the core temperature detection device 20 may include a second housing 210, a core temperature sensor 220, a second processor 230, and a second wireless communication module 240. The core temperature sensor 220, the second processor 230, and the second wireless communication module 240 may be located in the accommodation space formed by the second housing 210.

[0082] The core temperature sensor 220 may be electrically connected to the second processor 230 . The core temperature sensor 220 may be used to collect core temperature data inside the tobacco stack and send the core temperature data to the second processor 230 .

[0083] The second wireless communication module 240 can be electrically connected to the second processor 230. The second wireless communication module 240 can be used to wirelessly transmit the core temperature data forwarded by the second processor 230 to the gateway device, and transmit the core temperature data to the host computer through the gateway device.

[0084] The core temperature detection device provided in the embodiments of the present application can, on the one hand, realize the automatic detection of the core temperature inside the tobacco stack, reduce the workload of the detection personnel, and improve the detection efficiency; on the other hand, the core temperature detection device can wirelessly transmit the core temperature data inside the tobacco stack to the gateway device, and then transmit it to the host computer through the gateway device, thereby realizing automatic uploading and recording of data, reducing the error rate of data recording, and improving the detection accuracy; on the other hand, during the nitrogen filling and oxygen reduction process, the core temperature inside the tobacco stack can be automatically detected without personnel entering the low-oxygen working area, which can improve the detection safety and reduce the detection risk; on the other hand, the core temperature detection device adopts wireless communication, which reduces a lot of wiring and is convenient for layout.

[0085] According to some embodiments of the present application, the second processor 230 may optionally be a low-power chip. For example, the second processor 230 may be a low-power chip whose output current is less than a preset threshold in a low-power mode.

[0086] In this way, the life of the core temperature detection device can be improved to meet the actual use requirements of tobacco stack environmental parameter detection.

[0087] In some specific embodiments, optionally, similar to the first processor, the second processor 230 can use an ultra-low-power STM32L0 series chip, i.e., an STM32L0 series single-chip microcomputer. The STM32L0 series chip integrates a high-performance Arm Cortex-M0+ 32-bit RISC core with an operating frequency of 32 MHz, which can increase the battery life of the product while meeting the processing speed.

[0088] The second processor 230 has multiple pins. For example, the debug pins of the second processor 230 can be connected to a debug module, which can be used to debug the second processor 230. In addition, the second processor 230 can also be connected to a second reset module, which can be used to reset the second processor 230.

[0089] Figure 7 This is a circuit connection diagram of the core temperature sensor in the core temperature detection device provided in the embodiment of the present application. Figure 7 As shown, in some embodiments, the core temperature sensor 220 can optionally be a high-precision HT30 temperature sensor. The core temperature sensor 220 can be powered by a 3.3V power supply and communicate with the second processor 230 via an Inter-Integrated Circuit (I2C) bus. I2C communication requires only two signal lines: a data line (SDA) and a clock line (SCL). This simplified cabling reduces complexity.

[0090] Combine Figure 6 and Figure 7 As shown, in some embodiments, the core temperature sensor 220 is provided with a clock signal output terminal THSCL and a data signal output terminal THSDA. The clock signal output terminal THSCL of the core temperature sensor 220 is electrically connected to the clock signal input terminal of the second processor 230, and the data signal output terminal THSDA of the core temperature sensor 220 is electrically connected to the data signal input terminal of the second processor 230. The core temperature sensor 220 and the second processor 230 communicate via I2C, and the core temperature sensor 220 can transmit the collected core temperature data inside the tobacco stack to the second processor 230.

[0091] like Figure 7 As shown, the clock signal output terminal THSCL of the core temperature sensor 220 may be connected to a first pull-up resistor R48 , and the data signal output terminal THSDA of the core temperature sensor 220 may be connected to a second pull-up resistor R49 .

[0092] In some embodiments, the second wireless communication module 240 may optionally include a LoRa wireless communication module, which can achieve wireless data transmission over longer distances. LoRa (Long Range) wireless communication can, for example, achieve wireless communication over several kilometers, and the LoRa wireless communication module can be battery-powered and can operate in low-power mode, thereby further extending the service life and endurance of the core temperature detection device, meeting the actual use requirements of tobacco stack environmental parameter detection. In addition, LoRa wireless communication enhances anti-interference capabilities through technologies such as spread spectrum modulation and frequency hopping, making it suitable for working in complex channel environments.

[0093] The second wireless communication module 240 can communicate with the second processor 230 via a serial peripheral interface (SPI) communication method.

[0094] SPI communication typically has a high transmission rate, making it suitable for fast transmission of large amounts of data. Furthermore, it requires a simple pinout, typically requiring only four main signal lines, making it easy to connect to the hardware.

[0095] The second wireless communication module 240 may further be provided with a reset pin, and the reset pin may be electrically connected to the second processor 230 .

[0096] The inventors of this application further discovered that most current core temperature sensors are powered by lithium batteries. However, tobacco is flammable, so using lithium batteries to power them poses a risk of battery spontaneous combustion and tobacco burns. In light of this, in some embodiments of this application, the second processor 230 utilizes a low-power chip, such as an STM32L0 series chip, and a 3.6V dry cell battery is used to power the core temperature detection device, thereby reducing the risk of battery spontaneous combustion and tobacco burns.

[0097] Figure 8 This is another circuit diagram of the core temperature detection device provided in the embodiment of the present application. Figure 8 As shown, in some specific embodiments, optionally, the core temperature detection device 20 may further include a second power supply 250 and a second power supply chip 260. The second power supply 250 may be a 3.6V dry cell battery.

[0098] The second power chip 260 can be electrically connected to the second power supply 250. Specifically, the input end of the second power chip 260 can be electrically connected to the second power supply 250, and the output end of the second power chip 260 can be electrically connected to the core temperature sensor 220, the second processor 230, and the second wireless communication module 240. The second power chip 260 can be used to convert the 3.6V electrical signal output by the second power supply 250 into an electrical signal of a target voltage value, and power the core temperature sensor 220, the second processor 230, and the second wireless communication module 240 through the electrical signal of the target voltage value. The target voltage value can be flexibly adjusted according to actual conditions and is not limited in this application. For example, in some examples, the target voltage value can be 3.3V.

[0099] In this way, the embodiment of the present application uses a 3.6V dry cell battery to power the core temperature detection device, which can reduce the risk of battery spontaneous combustion and tobacco burning.

[0100] According to some embodiments of the present application, optionally, the second housing 210 is provided with ventilation holes (not shown in the figure). The material of the second housing and the number of ventilation holes can be flexibly adjusted according to actual conditions, and this application does not limit this.

[0101] In this way, the core temperature sensor and other components are integrated into the second housing, making it easy to carry and deploy, reducing deployment workload. In addition, the second housing is provided with a vent hole, which allows air to circulate inside and outside the second housing, facilitating the core temperature sensor to detect the core temperature data inside the tobacco stack.

[0102] According to some embodiments of the present application, one or more tobacco stacks may be optionally placed within each airtight tent, and each tobacco stack may be provided with at least one core temperature detection device 20. Each core temperature detection device 20 may be used to detect core temperature data within the corresponding tobacco stack, thereby improving the accuracy of environmental parameter detection for each tobacco stack.

[0103] In order to distinguish the data uploaded by different core temperature detection devices, in some embodiments, the core temperature detection device 20 may further include an eight-position dial switch. Figure 5 The structure of the eight-position dial switch 180 shown is the same. For details, please see Figure 5 , not shown separately here. An eight-position DIP switch can be electrically connected to the second processor 230. The eight-position DIP switch includes multiple switch buttons, such as eight switch buttons, each of which can be set to either an on or off state. The combination of multiple switch buttons in different states is used to set the data upload interval, communication address, communication channel, and / or communication mode of the core temperature detection device.

[0104] Each switch button can be set to "ON" or "OFF." A combination of multiple switch buttons can represent a specific binary number. For example, a combination of two switch buttons can represent binary numbers from 00 to 11, a combination of three switch buttons can represent binary numbers from 000 to 111, and a combination of eight switch buttons can represent binary numbers from 00000000 to 11111111.

[0105] The data upload interval is the time interval between two consecutive data uploads by the core temperature detection device. The uploaded data may include the core temperature data within the tobacco stack. The data upload interval can be flexibly adjusted based on actual conditions, such as 4 hours, 10 hours, or other time intervals, and this application does not limit this. The communication address, communication channel, and / or communication mode are used to distinguish data uploaded by different core temperature detection devices.

[0106] In some specific embodiments, the eight-position dial switch may optionally include a third eight-position dial switch and a fourth eight-position dial switch. Figure 5 The structure of the first eight-position dial switch 181 is the same as that of the fourth eight-position dial switch. Figure 5 The structure of the second eight-position dial switch 182 is the same as shown. For the specific structure, please see Figure 5 , which are no longer shown separately here.

[0107] The third eight-position DIP switch can be used to set the data upload time interval and communication channel of the core temperature detection device. For example, the combination of the first four switch buttons in the third eight-position DIP switch is used to set the data upload time interval of the core temperature detection device, that is, the binary number ranges from 0000 to 1111. The combination of the last four switch buttons in the third eight-position DIP switch is used to set the communication channel of the core temperature detection device, that is, the binary number ranges from 0000 to 1111. The fourth eight-position DIP switch can be used to set the communication address and communication mode of the core temperature detection device. For example, the combination of the first six switch buttons in the fourth eight-position DIP switch is used to set the communication address of the core temperature detection device, that is, the binary number ranges from 000000 to 111111. The combination of the last two switch buttons in the fourth eight-position DIP switch is used to set the communication mode of the core temperature detection device, that is, the binary number ranges from 00 to 11.

[0108] When the second wireless communication module 240 wirelessly transmits the core temperature data to the gateway device, it can send a binary number representing the communication address, communication channel and / or communication mode of the core temperature detection device to the gateway device, thereby facilitating the gateway device and / or the host computer to distinguish the data uploaded by different core temperature detection devices.

[0109] When detecting environmental parameters of tobacco stacks, multiple gateway devices and multiple core temperature detection devices 20 can be set up to detect the core temperature data inside multiple tobacco stacks. Each gateway device can be associated with at least one core temperature detection device 20, that is, it can receive data uploaded by at least one core temperature detection device 20. All core temperature detection devices 20 associated with the same gateway device can use the same communication mode and the same communication channel, and different core temperature detection devices 20 associated with the same gateway device can use different communication addresses. In other words, different communication modes and / or different communication channels can be used to distinguish different gateway devices, and different communication addresses can be used to distinguish different core temperature detection devices 20 associated with the same gateway device.

[0110] In this way, by setting the data upload time interval, communication address, communication channel and / or communication mode of the core temperature detection device through the eight-position dial switch, it is possible to distinguish the data uploaded by different core temperature detection devices while realizing automatic uploading and recording of environmental parameters of multiple tobacco stacks, thereby reducing the data recording error rate and improving detection accuracy.

[0111] Based on the same or similar technical concepts as the wireless temperature, humidity and oxygen content detection device and the core temperature detection device provided in the above embodiments, the embodiments of the present application also provide a moisture content detection device. The moisture content detection device can be arranged inside the tobacco stack, such as in the center of the tobacco stack. The moisture content detection device can be used to detect the moisture content data inside the tobacco stack.

[0112] Figure 9 This is a circuit diagram of a moisture content detection device provided in an embodiment of the present application. Figure 9 As shown, the moisture content detection device 30 may include a third housing 310, a moisture content sensor 320, a wired communication module 330, a third processor 340, and a third wireless communication module 350. The moisture content sensor 320, the wired communication module 330, the third processor 340, and the third wireless communication module 350 are located in the accommodation space formed by the third housing 310.

[0113] The moisture content sensor 320 may be used to collect moisture content data within the tobacco stack.

[0114] The wired communication module 330 is electrically connected between the moisture content sensor 320 and the third processor 340 . The wired communication module 330 can be used to send the moisture content data inside the tobacco stack collected by the moisture content sensor 320 to the third processor 340 .

[0115] The third wireless communication module 350 can be electrically connected to the third processor 340, and can be used to wirelessly transmit the moisture content data inside the tobacco stack forwarded by the third processor 340 to the gateway device, and transmit the moisture content data to the host computer through the gateway device.

[0116] The moisture content detection device provided in the embodiments of the present application can, on the one hand, realize the automatic detection of the moisture content inside the tobacco stack, reduce the workload of the detection personnel, and improve the detection efficiency; on the other hand, the moisture content detection device can wirelessly transmit the moisture content data inside the tobacco stack to the gateway device, and then transmit it to the host computer through the gateway device, thereby realizing automatic uploading and recording of data, reducing the error rate of data recording, and improving the detection accuracy; on the other hand, during the nitrogen filling and oxygen reduction process, the moisture content inside the tobacco stack can be automatically detected without personnel entering the low-oxygen working area, which can improve the detection safety and reduce the detection risk; on the other hand, the moisture content detection device adopts wireless communication, which reduces a lot of wiring and is convenient for layout.

[0117] According to some embodiments of the present application, the third processor 340 may optionally be a low-power chip. For example, the third processor 340 may be a low-power chip whose output current is less than a preset threshold in a low-power mode.

[0118] In this way, the life of the moisture content detection device can be improved to meet the actual use requirements of tobacco stack environmental parameter detection.

[0119] In some specific embodiments, similar to the first and second processors, the third processor 340 may optionally employ an ultra-low-power STM32L0 series chip, i.e., an STM32L0 series single-chip microcomputer. The STM32L0 series chip integrates a high-performance Arm Cortex-M0+ 32-bit RISC core with an operating frequency of 32 MHz, which can increase the battery life of the product while meeting the processing speed requirements.

[0120] The third processor 340 has multiple pins. For example, the debug pins of the third processor 340 can be connected to a debug module, which can be used to debug the third processor 340. In addition, the third processor 340 can also be connected to a third reset module, which can be used to reset the third processor 340.

[0121] Figure 10 This is a circuit connection diagram of the moisture content sensor and the wired communication module in the moisture content detection device provided in the embodiment of the present application. Figure 10As shown, in some embodiments, the moisture content sensor 320 may optionally be a TK100T moisture content sensor. The moisture content sensor 320 may be powered by a 3.3V power supply and perform data transmission with the third processor 340 via the wired communication module 330 .

[0122] Combine Figure 9 and Figure 10 As shown, in some embodiments, the wired communication module 330 can be a 485 communication chip, and a first voltage divider resistor (such as Figure 10 The resistors R97 and R98 shown in FIG. 4 are shown in FIG. 4 ), and a second voltage divider resistor (such as R97 and R98) may be connected between the 485 communication chip and the third processor 340. Figure 10 The first and second voltage-dividing resistors (shown as resistors R91, R92, and R93) can provide voltage division and current limiting protection. The data transmit pin SF_TX and the data receive pin SF_RX of the 485 communication chip can be electrically connected to different I / O pins of the third processor 340. The moisture content sensor 320 can transmit the collected moisture content data from the tobacco stack to the third processor 340 via the 485 communication chip.

[0123] In some embodiments, the third wireless communication module 350 may optionally include a LoRa wireless communication module, which can achieve wireless data transmission over longer distances. LoRa (Long Range) wireless communication can, for example, achieve wireless communication over several kilometers, and the LoRa wireless communication module can be battery-powered and can operate in low-power mode, thereby further extending the service life and endurance of the moisture content detection device and meeting the actual use requirements of tobacco stack environmental parameter detection. In addition, LoRa wireless communication enhances anti-interference capabilities through technologies such as spread spectrum modulation and frequency hopping, making it suitable for operation in complex channel environments.

[0124] The third wireless communication module 350 can communicate with the third processor 340 via a serial peripheral interface (SPI) communication method.

[0125] SPI communication typically has a high transmission rate, making it suitable for fast transmission of large amounts of data. Furthermore, it requires a simple pinout, typically requiring only four main signal lines, making it easy to connect to the hardware.

[0126] The third wireless communication module 350 may also be provided with a reset pin, which may be electrically connected to the third processor 340 .

[0127] The inventors of this application have further discovered that most current moisture content sensors are powered by lithium batteries. However, tobacco is flammable, so using lithium batteries to power them poses a risk of battery spontaneous combustion and tobacco burns. In view of this, in some embodiments of this application, the third processor 340 uses a low-power chip, such as an STM32L0 series chip, and a 3.6V dry cell battery is used to power the moisture content detection device, thereby reducing the risk of battery spontaneous combustion and tobacco burns.

[0128] like Figure 9 As shown, in some specific embodiments, optionally, the moisture content detection device 30 may further include a third power supply 360 and a third power supply chip 370. The third power supply 360 may be a 3.6V dry cell battery.

[0129] The third power chip 370 can be electrically connected to the third power supply 360. Specifically, the input end of the third power chip 370 can be electrically connected to the third power supply 360, and the output end of the third power chip 370 can be electrically connected to the moisture content sensor 320, the wired communication module 330, the third processor 340 and the third wireless communication module 350. The third power chip 370 can be used to convert the 3.6V electrical signal output by the third power supply 360 into an electrical signal of a target voltage value, and power the moisture content sensor 320, the wired communication module 330, the third processor 340 and the third wireless communication module 350 through the electrical signal of the target voltage value. The target voltage value can be flexibly adjusted according to actual conditions, and this application is not limited to this. For example, in some examples, the target voltage value can be 3.3V.

[0130] In this way, the embodiment of the present application uses a 3.6V dry cell battery to power the moisture content detection device, which can reduce the risk of battery spontaneous combustion and tobacco burning.

[0131] According to some embodiments of the present application, optionally, the third housing 210 is provided with ventilation holes (not shown in the figure). The material of the third housing and the number of ventilation holes can be flexibly adjusted according to actual conditions, and this application does not limit this.

[0132] In this way, the moisture content sensor and other components are integrated into the third housing, making it easy to carry and deploy, reducing deployment workload. In addition, the third housing has ventilation holes, through which air inside and outside the third housing can circulate, facilitating the moisture content sensor to detect moisture content data within the tobacco stack.

[0133] According to some embodiments of the present application, one or more tobacco stacks may be optionally placed within each airtight tent, and each tobacco stack may be provided with at least one moisture content detection device 30. Each moisture content detection device 30 may be used to detect moisture content data within a corresponding tobacco stack, thereby improving the accuracy of environmental parameter detection for each tobacco stack.

[0134] In order to distinguish the data uploaded by different moisture content detection devices, in some embodiments, the moisture content detection device 30 may further include an eight-position dial switch. Figure 5 The structure of the eight-position dial switch 180 shown is the same. For details, please see Figure 5 , not shown separately here. An eight-position DIP switch can be electrically connected to the third processor 340. The eight-position DIP switch includes multiple switch buttons, such as eight switch buttons, each of which can be set to an on or off state. The combination of multiple switch buttons in different states is used to set the data upload interval, communication address, communication channel, and / or communication mode of the moisture content detection device.

[0135] Each switch button can be set to "ON" or "OFF." A combination of multiple switch buttons can represent a specific binary number. For example, a combination of two switch buttons can represent binary numbers from 00 to 11, a combination of three switch buttons can represent binary numbers from 000 to 111, and a combination of eight switch buttons can represent binary numbers from 00000000 to 11111111.

[0136] The data upload interval is the time interval between two consecutive data uploads by the moisture content detection device. The uploaded data may include moisture content data within the tobacco stack. The data upload interval can be flexibly adjusted based on actual conditions, such as 4 hours, 10 hours, or other intervals, and this application does not limit this. The communication address, communication channel, and / or communication mode are used to distinguish data uploaded by different moisture content detection devices.

[0137] In some specific embodiments, the eight-position dial switch may optionally include a fifth eight-position dial switch and a sixth eight-position dial switch. Figure 5 The structure of the first eight-position dial switch 181 is the same as that of the sixth eight-position dial switch. Figure 5 The structure of the second eight-position dial switch 182 is the same as shown. For the specific structure, please see Figure 5 , which are no longer shown separately here.

[0138] The fifth eight-position dial switch can be used to set the data upload time interval and communication channel of the moisture content detection device. For example, the combination of the first four switch buttons in the fifth eight-position dial switch is used to set the data upload time interval of the moisture content detection device, that is, the binary number ranges from 0000 to 1111. The combination of the last four switch buttons in the fifth eight-position dial switch is used to set the communication channel of the moisture content detection device, that is, the binary number ranges from 0000 to 1111. The sixth eight-position dial switch can be used to set the communication address and communication mode of the moisture content detection device. For example, the combination of the first six switch buttons in the sixth eight-position dial switch is used to set the communication address of the moisture content detection device, that is, the binary number ranges from 000000 to 111111. The combination of the last two switch buttons in the sixth eight-position dial switch is used to set the communication mode of the moisture content detection device, that is, the binary number ranges from 00 to 11.

[0139] When the third wireless communication module wirelessly transmits the moisture content data to the gateway device, it can send a binary number representing the communication address, communication channel and / or communication mode of the moisture content detection device to the gateway device, thereby facilitating the gateway device and / or the host computer to distinguish the data uploaded by different moisture content detection devices.

[0140] When detecting environmental parameters of tobacco stacks, multiple gateway devices and multiple moisture content detection devices 30 can be set up to detect the moisture content data inside multiple tobacco stacks. Each gateway device can be associated with at least one moisture content detection device 30, that is, it can receive data uploaded by at least one moisture content detection device 30. All moisture content detection devices 30 associated with the same gateway device can use the same communication mode and the same communication channel, and different moisture content detection devices 30 associated with the same gateway device can use different communication addresses. In other words, different communication modes and / or different communication channels can be used to distinguish different gateway devices, and different communication addresses can be used to distinguish different moisture content detection devices 30 associated with the same gateway device.

[0141] In this way, by setting the data upload time interval, communication address, communication channel and / or communication mode of the moisture content detection device through the eight-position dial switch, it is possible to distinguish the data uploaded by different moisture content detection devices while realizing the automatic uploading and recording of environmental parameters of multiple tobacco stacks, thereby reducing the data recording error rate and improving the detection accuracy.

[0142] Based on the wireless temperature, humidity and oxygen content detection device 10, core package temperature detection device 20 and / or moisture content detection device 30 provided in the above embodiments, the embodiments of the present application also provide a tobacco stack environmental parameter detection system. The tobacco stack environmental parameter detection system may include a host computer and a gateway device. In addition, the tobacco stack environmental parameter detection system may also include at least one of the wireless temperature, humidity and oxygen content detection device 10, the core package temperature detection device 20 and the moisture content detection device 30.

[0143] For example, in some embodiments, a tobacco stack environmental parameter detection system may include a host computer, a wireless temperature, humidity, and oxygen content detection device 10, and a gateway device. The wireless temperature, humidity, and oxygen content detection device 10 is configured to detect temperature data, humidity data, and oxygen content data around the tobacco stack, and wirelessly transmit the temperature data, humidity data, and oxygen content data around the tobacco stack to the gateway device. The gateway device is communicatively connected to the wireless temperature, humidity, and oxygen content detection device and the host computer, respectively, and is configured to forward the temperature data, humidity data, and oxygen content data transmitted by the wireless temperature, humidity, and oxygen content detection device to the host computer.

[0144] For example, in some embodiments, a tobacco stack environmental parameter detection system may include a host computer, a core temperature detection device 20, and a gateway device. The core temperature detection device 20 is disposed within the tobacco stack and is configured to detect core temperature data within the tobacco stack and wirelessly transmit the core temperature data to the gateway device. The gateway device is communicatively connected to the core temperature detection device 20 and the host computer, respectively, and is configured to forward the core temperature data within the tobacco stack sent by the core temperature detection device to the host computer.

[0145] For example, in some embodiments, a tobacco stack environmental parameter detection system may include a host computer, a moisture content detection device 30, and a gateway device. The moisture content detection device 30 is disposed within the tobacco stack and is configured to detect moisture content data within the tobacco stack and wirelessly transmit the moisture content data to the gateway device. The gateway device is communicatively connected to the moisture content detection device 20 and the host computer, respectively, and is configured to forward the moisture content data within the tobacco stack sent by the moisture content detection device to the host computer.

[0146] For example, in some embodiments, the tobacco stack environmental parameter detection system may include a host computer and a gateway device. In addition, the tobacco stack environmental parameter detection system may also include at least two of a wireless temperature, humidity and oxygen content detection device 10, a core temperature detection device 20 and a moisture content detection device 30.
