Description

Technical Field

[0001] The utility model belongs to the technical field of measuring devices, and in particular relates to a cigarette package temperature and humidity detector. Background Art

[0002] Tobacco leaf, the primary raw material in the cigarette industry, is crucial to company profitability. Due to its high hygroscopicity, tobacco leaves are susceptible to pests and mildew during storage. Furthermore, their quality influences physical properties like elasticity and toughness, as well as their aroma and flavor. Furthermore, the storage environment also influences storage quality, making monitoring tobacco package temperature essential.

[0003] Currently, existing cigarette pack inspection devices typically consist of a probe, a transmission line, and a main unit. While capable of measuring cigarette pack temperature and humidity, these devices are often limited by space. In the complex and cramped environment of tobacco warehouses, the fixed length of the probe and the lack of overall flexibility make it difficult to precisely insert the probe into the ideal inspection position for different cigarette packs, making the device unsuitable for frequent use in tobacco warehouses. This not only significantly reduces inspection efficiency and prolongs the inspection cycle, but also increases the operator's workload and difficulty. Utility Model Content

[0004] The purpose of the utility model is to provide a cigarette package temperature and humidity detector with a retractable probe, accurate measurement and the ability to reduce the constraints of a narrow environment.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A cigarette package temperature and humidity detector, comprising:

[0007] Control components;

[0008] a second telescopic rod, one end of which is connected to the control assembly and a hollow channel is provided along the central axis of the second telescopic rod;

[0009] a first telescopic rod, slidably disposed in the hollow channel of the second telescopic rod;

[0010] A limiting portion, provided on the outer side of the first telescopic rod, for limiting and fixing the first telescopic rod and the second telescopic rod;

[0011] a probe needle connected to the end of the first telescopic rod away from the control assembly;

[0012] The temperature sensor and the humidity sensor are respectively arranged inside the probe needle and are used to send data to the control component through the input end.

[0013] Furthermore, the limiting portion is a telescopic marble, and the telescopic marble limits the sliding of the first telescopic rod relative to the second telescopic rod by providing a through hole matching the telescopic marble on the side wall of the second telescopic rod.

[0014] Furthermore, the control component includes:

[0015] a battery, disposed inside the control assembly and close to an upper wall of the control assembly housing;

[0016] A main control assembly is arranged below the battery and close to the lower wall of the control assembly housing;

[0017] A display, disposed on the lower surface of the control component housing and electrically connected to the main control component;

[0018] an antenna, disposed on a side of the control component housing and electrically connected to the main control component;

[0019] The indicator light is arranged on the upper surface of the housing of the control component and is electrically connected to the main control component.

[0020] Furthermore, the main control component includes: a main control circuit board, a clock, a single-chip microcomputer and a communication module; the clock is electrically connected to the corresponding electrical connections on one side of the main control circuit board, the single-chip microcomputer is electrically connected to the corresponding electrical connections in the middle of the main control circuit board, and the communication module is electrically connected to the corresponding electrical connections in the middle of the main control circuit board.

[0021] Furthermore, the display is electrically connected to each other through the corresponding electrical connections of the main control circuit board through the cable, the temperature sensor and the humidity sensor are electrically connected to the main control circuit board through wires, and the communication module is electrically connected to the antenna through wires and the corresponding circuit on the main control circuit board.

[0022] Furthermore, the housing of the control assembly is in a concave shape, and a folding portion is rotatably provided at the concave position of the housing, and the folding portion is fixedly connected to the second telescopic rod.

[0023] Furthermore, a plurality of fine hole structures are provided on the outer wall of the probe needle, and the positions of the fine hole structures correspond to the temperature sensor and the humidity sensor.

[0024] Furthermore, the temperature sensor is a thermocouple temperature sensor or a thermal resistor temperature sensor, and the humidity sensor is a capacitive humidity sensor or a resistive humidity sensor.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] The present invention completes the detection operation by integrating the control component, the first telescopic rod, the second telescopic rod and the probe needle into one body. Specifically, by configuring the existing rod body to be a rod body that can be telescoped back and forth with a limit portion, the problem that traditional probes are difficult to accurately measure the position to be detected due to the limitation of their fixed length is solved. At the same time, unlike the traditional structure in which the probe and the control component are separated, the present device improves the operator's flexibility in hand-held operation by integrating the four parts into one body, and reduces the operator's labor intensity and work difficulty.

[0039] In order to make the technical means, creative features, purpose and efficacy of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making creative work are all within the scope of protection of the present invention. The experimental methods in the following embodiments are all conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0040] like Figure 1-Figure 7 , in this embodiment, it includes: a probe assembly 1 and a control assembly 2 connected to the probe assembly 1;

[0041] The probe assembly 1 includes: a probe needle 14, a first telescopic rod 10, and a second telescopic rod 11; the probe needle 14 is connected to one end of the first telescopic rod 10, and the other end of the first telescopic rod 10 is slidably arranged in the hollow channel of the second telescopic rod 11, and the first telescopic rod 10 is fixed to the second telescopic rod 11 by the limit of the limit part 12;

[0042] It should be noted that the limiting portion 12 is a telescopic marble, which is arranged in a circular array on the outer periphery of the first telescopic rod 10, and a through hole matching the telescopic marble is provided on the end of the second telescopic rod 11 close to the first telescopic rod 10;

[0043] Specifically, when a longer telescopic rod is needed for detection, the first telescopic rod 10 is pulled out of the hollow channel of the second telescopic rod 11. At this time, the telescopic ball is in a compressed state because it is inside the second telescopic rod 10. When the first telescopic rod 10 drives the telescopic ball to be pulled out along the channel and reaches the through hole opened in the second telescopic rod 11, the telescopic ball is in an extended state, and the first telescopic rod 10 and the second telescopic rod 11 are fixed; conversely, when the telescopic rod needs to be shortened, the telescopic ball is compressed and the first telescopic rod 10 is pushed into the channel until the first telescopic rod 10 returns to the short state;

[0044] It should be noted that when the first telescopic rod 10 is retracted into the inner space of the second telescopic rod 11 , the probe needle 14 is located outside the probe needle 14 ;

[0045] It should be noted that a temperature sensor 15 and a humidity sensor 16 are provided inside the probe needle 14;

[0046] Specifically, through the detection of the two sensors, the data is finally sent to the control component 2 through the input end;

[0047] Among them, the control component 2 includes:

[0048] The battery 21 is disposed inside the control assembly 2 and close to the upper wall of the housing of the control assembly 2;

[0049] The main control assembly is arranged below the battery 21 and close to the lower wall of the control assembly 2 housing;

[0050] The display 24 is provided on the lower surface of the housing of the control component 2 and is electrically connected to the main control component;

[0051] Antenna 22, provided on the side of the housing of the control component 2 and electrically connected to the main control component;

[0052] The indicator light 25 is provided on the upper surface of the housing of the control component 2 and is electrically connected to the main control component;

[0053] The outer shell of the control assembly 2 is in the shape of a concave character, wherein a folding portion 13 is provided at the concave position of the outer shell;

[0054] It should be noted that the folding portion 13 is connected to the housing via a rotating shaft, and the folding portion 13 is connected outwardly to the second telescopic rod 11;

[0055] Specifically, when the control component 2 needs to be in close contact with the detection smoke box 3, the folding button 20 is pressed, and the probe component 1 and the control component 2 become vertical. Finally, the probe component 1 is vertically inserted into the detection smoke box 3, and the control component 2 and the detection smoke box 3 are in close contact.

[0056] In this embodiment, the main control component includes: a main control circuit board 23, a clock 801, a single chip microcomputer 802 and a communication module 803;

[0057] Among them, the clock 801 is electrically connected to the corresponding electrical connections on one side of the main control circuit board 23, the single-chip computer 802 is electrically connected to the corresponding electrical connections in the middle of the main control circuit board 23, the communication module 803 is electrically connected to the corresponding electrical connections in the middle of the main control circuit board 23, the display 24 is electrically connected to the corresponding electrical connections of the main control circuit board 23 through the wiring, the temperature sensor 15 and the humidity sensor 16 are electrically connected to the main control circuit board 23 respectively through wires, and the communication module 803 is electrically connected to the antenna 22 through wires and the corresponding circuits on the main control circuit board 23.

[0058] In this embodiment, a fine hole structure is provided on the outer wall of the probe needle 14 . The position of the fine hole structure is opposite to the temperature sensor 15 and the humidity sensor 16 . A dustproof net is covered along the periphery of the fine hole structure.

[0059] In this embodiment, the temperature sensor 15 is a thermocouple temperature sensor or a thermal resistor temperature sensor, and the humidity sensor 16 is a capacitive humidity sensor or a resistive humidity sensor.

[0060] like Figure 8-11The working process includes system initialization, peripheral initialization, network initialization, data measurement and data transmission. The specific steps are as follows:

[0061] (1) System initialization phase:

[0062] At the initial system startup, comprehensive system interface initialization begins. The clock is accurately set, providing a stable time base for the entire system. GPIO (General Purpose Input / Output) pins are initialized and configured to ensure proper communication with external devices. Timers are enabled, playing a crucial role in subsequent timing processes, such as controlling sleep duration and data collection intervals. The serial port, a key communication interface, utilizes efficient DMA (Direct Memory Access) for communication. Its baud rate is set to 115200 baud, which meets the data transfer requirements between the system and external devices or debug terminals, ensuring timely and accurate data exchange. Simultaneously, other system interfaces, such as I2C and SPI, are also initialized, laying the foundation for communication with various peripherals.

[0063] (2) Peripheral initialization stage:

[0064] Initialize the power management chip and enable the LDO (low-dropout linear regulator) to provide a stable and appropriate power supply to all system modules. Next, initialize the FLASH (flash memory) and FRAM (ferroelectric random access memory) to ensure proper functioning of the data storage media. Load the firmware from the storage device into the RAM (running memory), a critical step for the system's proper functioning. Finally, interact with the temperature and humidity sensors, reading their ID information for accurate sensor identification and data reading, preparing for environmental data collection.

[0065] (3) Network initialization phase:

[0066] The system attempts to obtain the CCID (Integrated Circuit Card Identifier), a key identifier for the device on the network. It then checks the M5311's network connection status. This process is crucial, as successful network connection is necessary for the device to communicate with external servers. If it detects that it is not connected to the network, the system automatically attempts to reconnect, demonstrating a degree of self-recovery. However, if network connection fails after three consecutive queries, the system shuts down the M5311 to avoid excessive resource consumption and waits for the next connection opportunity. Once network connection is successful, the system immediately connects to the server via UDP (User Datagram Protocol) and establishes a connection flag, indicating that the device now has network conditions for data transmission with the server.

[0067] (4) Sleep mode stage:

[0068] After completing the initialization described above, the system enters sleep mode for 5 minutes. During this period, most system functions remain in a low-power standby state, with only essential wake-up mechanisms remaining for monitoring. This helps reduce system energy consumption and extend the device's overall battery life. This sleep mechanism can effectively improve the device's practicality, especially in power-demanding applications.

[0069] (6) Measurement data stage:

[0070] After the 5-minute sleep mode ends, the system reactivates. First, the LDO is turned on to ensure stable power supply to all modules. Next, the corresponding I2C interfaces are initialized, which are key channels for communication with the temperature and humidity sensors. The temperature and humidity sensor IDs are read again to confirm proper connection and identification. The firmware is then reloaded into the RAM to ensure the integrity and accuracy of the system's functional logic. Parameter configuration is performed to prepare for the upcoming data reading. After a 2.5-second delay, which ensures sufficient time for the sensors to stabilize data collection, the temperature and humidity values, as well as the current time, are read. Finally, the collected data is carefully written to the flash memory in a specific format, with the write location accurately calibrated for rapid location and extraction during subsequent data reading and processing.

[0071] (7) Data sending phase:

[0072] When a wake-up interrupt arrives, the system first checks the connection flag. If the connection flag is True, indicating a normal network connection with the server, the system then reads data from the flash memory. Based on the distance between the read and write pointers, the system intelligently determines whether a single or multiple frames of data are being sent. This data processing method flexibly adapts to transmission requirements of varying data volumes. It then reads signal quality information and combines it with other important data, such as the CCID, device ID, firmware version, and IP address, into a complete communication protocol frame according to the established communication protocol. This frame is then sent to the server and awaits an ACK (acknowledgement) signal from the server. Upon receiving the ACK, the next frame is positioned to be sent, preparing for the next data transmission. If the connection flag is False, indicating a network connection anomaly or not yet established, the system does not transmit data and instead turns off the LDO, entering a low-power standby state, awaiting the next timer interrupt to retry network connection and data transmission.

[0073] (8) Normal sleep mode stage:

[0074] After completing data transmission, the system enters regular sleep mode, with a default wake-up time of once an hour. In regular sleep mode, the system further reduces power consumption. With the exception of a few modules, such as timers, that maintain the wake-up mechanism, most other functional modules cease operation. This periodic sleep and wake-up mechanism ensures the system can continue to perform its tasks while minimizing unnecessary energy consumption. This allows the device to operate stably for extended periods of unattended operation, making it suitable for a variety of applications with comprehensive requirements for power consumption and sustainability, such as environmental monitoring and remote data collection. Furthermore, when necessary, the system repeats the above steps to ensure continuous data collection and transmission, and stable system operation.

[0075] It should be noted that the circuits, electronic components and modules involved are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.

[0076] Measurement process:

[0077] When the device is inserted into the cigarette pack, it sleeps for 5 minutes and then starts measuring and uploading data 5 minutes later, avoiding the problem of high temperature of the measuring pack core.

[0078] 1. In standby mode, press and hold the button for 8 seconds, the indicator light will flash slowly, and there will be two beeps, then the device will turn on and enter data collection mode;

[0079] 2. Enter 5-minute sleep mode;

[0080] 3. If the 5-minute sleep time is up, the temperature, humidity, moisture and other data will be collected and transmitted to the backend at the same time;

[0081] 4. Enter normal sleep mode (wake up once every hour by default);

[0082] 5. If there is a single key press, the process will start from step 2;

[0083] 6. If you need to stop measuring midway, press and hold the button for 8 seconds, the indicator light will flash quickly, and it will beep three times, then it will enter the standby state.

[0084] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
