[0027] like Figure 1-Figure 3 As shown, this embodiment provides a cold chain monitoring system with an intelligent temperature scale, including: a box body 1, a humidifying and cooling component 2, a plurality of temperature scale components 3 and a reading and writing component; a storage space is formed inside the box body 1, and the storage space is used to store items that need to be transported; the humidifying and cooling component 2 is installed on the outer wall surface of the box body 1, and the outlet end of the humidifying and cooling component 2 is connected to the storage space through a pipeline, and can transport cold air or humidified air to the storage space; a plurality of temperature scale components 3 are attached to the items stored in the storage space, and the temperature scale component 3 includes a main board 301, an RFID electronic temperature measuring chip 302, a memory 303, a first transceiver antenna 304 and a second transceiver antenna 305, and the RFID electronic temperature measuring chip 302, The memory 303, the first transceiver antenna 304 and the second transceiver antenna 305 are all installed in the main board body 301, and the RFID electronic temperature measurement chip 302 is electrically connected to the memory 303, the first transceiver antenna 304 and the second transceiver antenna 305 respectively. The memory 303 is electrically connected to the first transceiver antenna 304. One side of the main board body 301 can be pasted on the object, and a through hole corresponding to the RFID electronic temperature measurement chip 302 is opened on the side; the read-write component is electrically connected to the first transceiver antenna 304 for batch reading the temperature information in the memory 303, and the read-write component is electrically connected to the second transceiver antenna 305 for obtaining the temperature information of a single object.

[0028] With the growing demand for cold chain logistics, monitoring the temperature of items during transportation has become crucial. Although traditional RFID wireless temperature measurement methods can monitor temperature, they usually require the use of specific RFID readers and do not support reading through general devices such as smartphones, limiting usage scenarios. The above solution provides a cold chain monitoring system with an intelligent temperature scale, which aims to achieve diversified temperature reading and improve the flexibility and efficiency of logistics monitoring. A storage space for items to be transported is formed inside the box 1, and the humidification and refrigeration component 2 is installed on the outer wall of the box 1, and cold air or humidified air is delivered to the storage space through a pipe to maintain or adjust the temperature and humidity in the storage space. The temperature scale component 3 is attached to the object, and specifically includes a main board body 301, an RFID electronic temperature measuring chip 302, a memory 303, a first transceiver antenna 304 and a second transceiver antenna 305. The RFID electronic temperature measuring chip 302 is used to measure the temperature and store the data in the memory 303. The first transceiver antenna 304 is electrically connected to the read-write component and is used to batch read the temperature information in the memory 303. The second transceiver antenna 305 is electrically connected to the read-write component and the RFID electronic temperature measuring chip 302, allowing the read-write component to directly obtain the temperature information of a single object through near field communication (NFC) or RFID. One side of the main board body 301 can be attached to the object and is provided with a through hole corresponding to the RFID electronic temperature measuring chip 302; in addition, the read-write component is electrically connected to the first transceiver antenna 304, and can batch read the temperature information stored in multiple temperature scale components 3; and is electrically connected to the second transceiver antenna 305, and can individually read and verify the temperature information of a single object. The system supports reading temperature information through both RFID and NFC, which improves the versatility and convenience of the system, allowing staff to monitor temperature changes at any time to ensure that the refrigerated temperature of items during transportation meets the requirements, improves the efficiency and accuracy of cold chain logistics monitoring, and reduces transportation risks.

[0029] It is worth mentioning that the read-write component is external and has no connection with the box 1. The read-write component can be installed in the control room or cab of the cold chain transport vehicle to facilitate staff to monitor at any time.

[0030] Furthermore, the main board 301 is provided with a fastener 306, and the main board 301 can fit the RFID electronic temperature measurement chip 302 to the surface of the object through the fastener 306. The fastener 306 provided on the main board 301 can be in various forms, such as a clip, a magnet, an adhesive, a hook, etc., and is used to fix the main board 301 and the RFID electronic temperature measurement chip 302 to the surface of the object. Through the use of the fastener 306, the RFID electronic temperature measurement chip 302 can be more closely attached to the surface of the object, which helps to improve the accuracy of temperature measurement, because the closer the contact between the temperature measurement chip and the object, the more accurate the temperature transfer and measurement. Fasteners 306 can ensure that the temperature scale component 3 will not fall off during transportation, and can remain stable even when the object is moved or vibrated. Different designs of fasteners 306 can adapt to the surfaces of objects of various shapes and materials, increasing the versatility of the system. Well-designed fasteners 306 should allow staff to quickly and easily install and remove the temperature scale component 3 without causing damage to the object or the temperature scale itself. In addition, the design of the main body 301 and fasteners 306 ensures that the RFID electronic temperature measurement chip 302 can stably measure the temperature of the object for a long time, which is crucial for temperature monitoring in cold chain logistics. Through such a design, the cold chain monitoring system can more reliably monitor the temperature of the object, thereby improving the quality and safety of the entire logistics process. This is particularly important for the transportation of fresh food, agricultural and sideline products, vaccines, and medicines that require precise temperature control.

[0031] Specifically, the fastener 306 is an elastic band. The elastic band has good flexibility, can adapt to objects of different shapes, is easy to wrap and fix, and can stretch and return to its original shape, so that it can fit tightly on irregular or curved surfaces. In addition, the elastic band is easy to operate, and can quickly fix the temperature scale assembly 3 on the object, and is also convenient to disassemble.

[0032] Optionally, one end of the fastener 306 is fixedly connected to the main board body 301, and the other end is snap-fitted to the main board body 301. One end of the fastener 306 is fixedly connected to the main board body 301, which ensures the stability of the temperature scale assembly 3, while the snap-fit ​​design of the other end provides a certain flexibility, which is convenient for installation and adjustment. The snap-fit ​​design allows the user to easily fix the temperature scale assembly 3 on the object, and the tension of the fastener 306 can be adjusted as needed. Since a part of the fastener 306 is re-snap-fittable, it means that after removing the temperature scale assembly 3, the same fastener 306 can be reused, thereby reducing the replacement cost; the snap-fit ​​design allows the fastener 306 to adapt to objects of different sizes, because the user can adjust the snap-fit ​​position according to the specific size of the object. This design ensures that the fastener 306 will not fall off accidentally during use, thereby protecting the safety of the temperature scale assembly 3. If the fastener 306 is damaged or needs to be replaced, this design makes the maintenance and replacement process easier.

[0033] Furthermore, the transceiver distance of the first transceiver antenna 304 is 0-20m, and the transceiver distance of the second transceiver antenna 305 is 0-10m. By providing two antennas with different reading distances, the system can adapt to different application scenarios and user needs, increasing its flexibility and practicality. The longer reading distance of the first transceiver antenna 304 can improve work efficiency because it allows multiple temperature scales to be read at one time, reducing the time and labor cost of reading one by one. The shorter reading distance of the second transceiver antenna 305 provides higher accuracy and is suitable for situations where detailed monitoring of individual items is required.

[0034] Furthermore, the reading and writing component includes an RFID reader and a portable electronic device, wherein the RFID reader is used to batch read the temperature information in the memory 303, and the portable electronic device is used to obtain the temperature information of a single item. The RFID reader is used to batch read the temperature information stored in multiple temperature scale components 3, which is suitable for large-scale monitoring and management scenarios, such as warehouses, logistics centers or cold chain transportation vehicles. It may be equipped with a longer reading distance and can cover a larger area at one time to improve work efficiency. The portable electronic device is used to obtain the temperature information of a single item, which is suitable for scenarios that require fine monitoring or temperature checks on a single item under specific circumstances. The portable electronic device may include a smart phone, a tablet computer or other handheld devices, which can communicate with the temperature scale component 3 via NFC technology. Combining RFID readers and portable electronic devices, the system provides flexibility, allowing users to choose the most appropriate reading method according to actual conditions. By using RFID technology and NFC technology, the system can be compatible with existing logistics and monitoring equipment, while also being able to take advantage of the popularity of modern electronic devices; and the use of portable electronic devices improves the convenience of the system, because staff can carry them with them and obtain temperature information at any time. In addition, RFID readers and portable electronic devices can be connected to a central database or cloud service to achieve real-time transmission and storage of data, facilitating subsequent analysis and processing.

[0035] In some embodiments, a waterproof shell 307 is also included, and the waterproof shell 307 is covered on the main body 301 and has a through hole opposite to the through hole. The waterproof shell 307 provides additional protection for the temperature scale component 3, so that it can be used in a humid or watery environment, such as a cold storage, rain that may be encountered during transportation, or during the cleaning process. The design of the waterproof shell 307 improves the durability of the entire temperature scale component 3, allowing it to withstand more severe environmental conditions. Through this design, the cold chain monitoring system can better adapt to a changing working environment, while protecting the temperature scale component 3 from the threat of moisture and other potential damage, ensuring the continuity and accuracy of temperature monitoring.

[0036] Specifically, the waterproof shell 307 is made of silica gel. Silica gel has good flexibility and can be designed to fit the shape of the main board body 301 tightly while being able to withstand the stress caused by the shape change of the object. It is also a known waterproof material that can effectively prevent water penetration and protect the internal electronic components. At the same time, silica gel can remain stable over a wide temperature range, which makes it suitable for use in cold chain monitoring systems that may experience extreme temperature changes.

[0037] Preferably, a temperature sensor and a humidity sensor are also included. The temperature sensor is installed in the storage space and is electrically connected to the humidifying and refrigerating component 2. The humidity sensor is installed in the storage space and is electrically connected to the humidifying and refrigerating component 2. By installing the temperature sensor and the humidity sensor, the system can monitor the temperature and humidity conditions in the storage space in real time, which is crucial to ensure the quality and safety of the items. The data collected by the sensor can be used to accurately control the operation of the humidifying and refrigerating component 2 to maintain ideal environmental conditions. The electrical connection between the sensor and the humidifying and refrigerating component 2 can realize automatic control, reduce manual intervention, and improve efficiency.
