Description

Technical Field

[0001] This utility model relates to the field of logistics transportation monitoring technology, and in particular to a parcel transportation status monitoring device and a box. Background Technology

[0002] With the rapid development of the global e-commerce and logistics industry, parcel transportation volume has exploded. During transportation, parcels frequently face complex environments such as stacking, compression, drops, moisture, and high temperatures. These factors can not only cause damage to goods but also trigger disputes of liability between users and logistics companies. Current technologies largely rely on manual visual inspection or environmental recorders deployed in certain stages, but these methods suffer from problems such as complex installation, high costs, and inability to comprehensively monitor the status of parcels.

[0003] In the prior art, utility model patent CN207650403U proposes a real-time package tracking device, mainly used to solve the problem that customers cannot keep track of the package's location in real time during traditional express delivery. This device consists of three parts: an RFID tag, a vehicle-mounted terminal, and a remote server. However, this patented device only focuses on acquiring the package's location information and does not effectively monitor changes in the package's posture, environmental conditions, and stress during transportation. In actual transportation, packages may encounter collisions, drops, severe vibrations, pressure, or even inversion, all of which can damage the contents. However, this device does not integrate corresponding sensor modules and cannot capture these physical state changes, leading to uncontrollable transportation risks and difficulty in tracing after-sales issues. Utility model patent CN205384695U discloses a cargo monitoring device and system, mainly used for real-time monitoring and anti-theft management of cargo units during express delivery and delivery. This device, by installing a GPS module, Bluetooth module, motion monitoring module, and mobile data communication module on the cargo unit, can acquire the cargo unit's location, movement status, and communication signals with the delivery person's mobile terminal in real time. However, it lacks the ability to sense environmental parameters such as temperature, humidity, and pressure. In actual logistics transportation, these factors often have a direct impact on the safety of the items inside the package, especially when transporting fragile goods, precision instruments, or environmentally sensitive items (such as medicines and fresh produce). The device cannot provide effective monitoring and early warning, limiting its applicability in high-standard transportation applications. While the device integrates positioning, Bluetooth, motion monitoring, Hall effect sensors, and communication modules, offering numerous functions, it lacks low-power consumption or energy harvesting design, which will lead to battery life issues in long-distance transportation or power-constrained scenarios.

[0004] This invention can monitor the temperature and humidity inside a package, the pressure it experiences, and any impact damage, as well as any accidental opening or deviation from the transport route during transit. External personnel can use NFC-enabled devices such as mobile phones to read the monitoring results of the package's internal environment without interrupting the packaging. This enhances the convenience and effectiveness of transport compliance verification and provides a clear traceability path for subsequent issues such as package damage or lost contents.

[0014] Furthermore, the device is also equipped with a plastic grid structure.

[0015] Furthermore, the antenna area of ​​the near-field communication module faces outwards from the enclosure.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0029] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0030] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation besides the orientation of the device as described in the figures. For example, if the device in the figures is inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0031] Figure 1In this invention, a parcel transportation status monitoring device includes a working part and a power supply part. The working part includes a microcontroller and a sensing and communication module. The sensing and communication module includes a temperature and humidity sensor, a pressure sensor 8, a photosensitive sensor 1, an inertial measurement unit, a near-field communication module 7, and a positioning module. The microcontroller establishes communication connections with each component in the sensing and communication module through an inter-integrated circuit bus (I2C bus) to form a stable data acquisition device.

[0032] The sensing and communication module generates environmental and status signals, the microcontroller collects these signals, analyzes, records, and stores them, and the power supply provides power to the operating components.

[0033] Among them, environmental and status signals include temperature and humidity signals, pressure signals, light signals, attitude and motion signals, position signals, and near-field communication interaction signals.

[0034] Furthermore, the power supply section includes a battery and an external TYPE-C power supply interface 4, through which the external power supply provides power to the device.

[0035] For the microcontroller (MCU), ultra-low-power microcontrollers such as the STM32L476 and STC8G1K08A 36I-SOP8 can be selected; for the inertial measurement unit (IMU), the BMI270 can be selected; and for the near field communication module (NFC), the NTAGI can be selected. 2 The C Plus2K series chip, for example, uses the u-blox M10 chip for the positioning module. The battery is an SR-type zinc-silver oxide button cell. The internal module connections and communication methods are as follows: Figure 1 As shown.

[0036] Furthermore, the temperature and humidity sensor is model STTS22H. The temperature and humidity sensor is used to monitor the temperature and humidity inside the package in real time to ensure that the environment during transportation meets the storage requirements of the goods, and outputs temperature and humidity signals to the microcontroller.

[0037] The pressure sensor 8 is model FSR UX 402. The pressure sensor 8 is used to sense whether the package is being squeezed or subjected to abnormal external force, and outputs a pressure signal to the microcontroller.

[0038] The photosensitive sensor 1 is model MAX44007. It is used to determine whether the package has been opened during transportation. Because there is no light inside the package when it is normally closed, once it is opened, the external light will be detected, and a light signal will be output to the microcontroller.

[0039] Furthermore, the inertial measurement unit integrates a three-axis accelerometer, which can be used to identify changes in the package's orientation, vibration, or collisions during transportation, thereby assessing whether rough handling occurred during logistics. It also outputs attitude and motion signals to the microcontroller.

[0040] The near-field communication module 7 integrates an EEPROM memory for short-range wireless communication, facilitating data reading and writing, and is suitable for operations such as status query, identification, and device debugging. It also outputs near-field communication interaction signals to the microcontroller.

[0041] The positioning module is used to achieve real-time package location tracking, record transportation routes, and improve logistics transparency. It also outputs location signals to the microcontroller.

[0042] The power supply section includes an integrated built-in button battery and an external Type-C power interface 4. The built-in battery provides power for daily operation, supporting independent and stable operation of the module during package transportation. If the battery level is low, the microcontroller writes low battery information to the near-field communication module 7. Upon arrival at the transit station, the near-field communication module 7 is activated to remind staff to replace the battery. When the device requires maintenance, debugging, or firmware upgrades, an external power source can be connected via the Type-C interface to achieve higher power and more stable power supply. The battery is designed to be replaceable, improving the maintainability and lifespan of the device. During maintenance, the Type-C interface can be used to communicate with the microcontroller via serial port.

[0043] Figure 2-4 This utility model embodiment also includes a parcel transportation status monitoring box, based on the aforementioned parcel transportation status monitoring device. The overall structure is compact and easy to integrate into a parcel box. It includes a device housing, on the outer surface of which are mounted a photosensitive sensor 1, a power supply interface 4, a near-field communication module 7, a first device fixing magnet 5, and a first copper terminal 6. The power supply interface 4 is a TYPE-C interface, used for device debugging, firmware upgrades, or external power supply. The first device fixing magnets 5, in conjunction with the magnetic structure within the box, are used for quick installation and stable fixation. There are four magnets in total, each approximately 1cm in diameter and 3mm thick, embedded in the plastic shell of the device. There are two first copper terminals 6, which serve as signal connections to the pressure sensor 8 inside the box. The specific dimensions are approximately 1.5cm × 12cm × 5cm. The device contains a temperature and humidity sensor, an inertial measurement unit, and a positioning module.

[0044] The internal structure of the enclosure is specifically designed to accommodate monitoring devices. The bottom of the enclosure has recessed areas. The groove is equipped with a second copper terminal 11 and a second device fixing magnet 10. The first device fixing magnet 5 and the second device fixing magnet 10 cooperate to fix the device on the box. There are a total of 4 second device fixing magnets 10, and their size is the same as the magnets on the monitoring device. They form an adsorption structure with the magnets to achieve quick positioning and installation of the device.

[0045] Furthermore, the top cover of the enclosure is equipped with a cover support column 9 at the corresponding position of the pressure sensor 8. The first copper terminal 6 and the second copper terminal 11 are connected to each other to complete the transmission of the pressure signal generated by the pressure sensor 8. The pressure sensor 8 is installed inside the enclosure to sense changes in the pressure of the top cover.

[0046] Furthermore, the device is also equipped with a battery compartment 3, which contains a battery, and can also be powered by an external power source through the power supply interface 4.

[0047] Furthermore, such as Figure 3 As shown, the device is also equipped with a plastic grid structure 2, which facilitates the entry of external ambient air into the device, thereby enabling the temperature and humidity sensor to accurately sense the internal environmental conditions of the package.

[0048] Furthermore, the antenna area of ​​the near-field communication module 7 faces outwards from the enclosure, facilitating non-contact data reading by external devices.

[0049] During installation, the monitoring device is magnetically attached to the inner wall of the enclosure, with its NFC antenna facing outwards. Operators can interact with the data via mobile phones and other terminal devices. At the same time, the copper terminals form electrical contact with the enclosure pressure sensor 8 to ensure the integrity and effectiveness of the environmental perception data.

[0050] like Figure 5 As shown, the usage process of this device is as follows: Once the package is sealed and the monitoring device is installed in the groove inside the box via the magnetic attraction between the first device fixing magnet 5 and the second device fixing magnet 10, staff can use external devices such as mobile phones to approach the near-field communication module 7, activate the module, and write the target transportation environment parameters. The written parameters include: the upper and lower limits of temperature and humidity from the temperature and humidity sensor, the upper limit of pressure from the pressure sensor 8, the sampling period of the microcontroller, operator identification information, and configuration timestamps, thus completing the pre-transport parameter preset.

[0051] After receiving the configuration data from the near-field communication module 7, the microcontroller automatically switches to monitoring mode; according to the set sampling period, it periodically collects environmental and status data such as temperature, humidity, pressure, orientation, and positioning inside the package via the I2C bus.

[0052] The microcontroller analyzes the collected data to determine if any parameters exceed the limits. If any parameter exceeds the set threshold, the excess information and the corresponding timestamp are immediately recorded and written into the EEPROM of the near-field communication module 7, forming an immutable exception log.

[0053] During non-sampling periods, the microcontroller and its connected sensor modules automatically enter a low-power standby state to extend the device's battery life and wait for the next sampling trigger.

[0054] When a package is subjected to a collision or vibration during transportation, the inertial measurement module actively detects abnormal acceleration and triggers the microcontroller to record the current attitude and collision information in real time, marking it as a potential violent transportation event.

[0055] If the package is opened abnormally, the photosensitive sensor 1 will detect the change in ambient light and actively wake up the microcontroller to trigger the recording of the abnormal opening status, ensuring the integrity and traceability of the transportation process.

[0056] The microcontroller writes the abnormal state triggered by the inertial measurement module or the photosensitive sensor 1 into the EEPROM of the near-field communication module 7, and then switches back to the low-power state to ensure the energy efficiency and continuous operation capability of the device.

[0057] When the package arrives at the transit station, staff can activate the near-field communication module 7 via an external reading device to retrieve all historical data stored in the EEPROM and upload it to the cloud server. The device will then analyze this data to determine if any abnormal behavior, such as rough handling or unauthorized opening of the package, occurred during transport.

[0058] After the transportation process is completed, the device enters reset mode, clears temporary data, and waits for the start of the next transportation task, forming a closed-loop management.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
