[0002] In the current medical environment, the demand for clinical blood is increasing year by year. Given the particularity and sensitivity of blood and its products, professional means and equipment must be used in their storage and transportation, especially in emergency rescue and strategic resource dispatch situations, the key role of blood is becoming more and more prominent. Therefore, it is particularly important to monitor the location of blood during transportation, ensure that blood is not illegally taken out, and verify whether the blood is successfully delivered to the destination.

[0003] At present, the main method of blood transportation is through blood transfer boxes. The current transport boxes have relatively complete functions and can basically monitor the temperature and humidity information of the blood bags in the box and locate their positions. However, blood transportation currently relies mainly on 4G to send information. When the 4G signal is weak or cannot be covered, this method will cause data packet loss due to signal loss. In addition, in the 4G network, attackers may intercept and tamper with data through MitM attacks (man-in-the-middle attacks), and the potential data security risks of external systems make the sensitive information of the blood transfer box subject to interruption and leakage, and cannot safely and effectively provide real-time data of blood, thereby limiting the emergency response capabilities of staff.

[0017] A specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0018] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the technical solutions of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0019] At present, the main method of blood transportation is through blood transfer boxes. The current transport boxes have relatively complete functions and can basically monitor the temperature and humidity information of the blood bags in the box and locate their positions. However, blood transportation currently relies mainly on 4G to send information. When the 4G signal is weak or cannot be covered, this method will cause data packet loss due to signal loss. In addition, in the 4G network, attackers may intercept and tamper with data through MitM attacks. In addition, the potential data security risks of external systems make the sensitive information of the blood transfer box subject to interruption and leakage, and cannot safely and effectively provide real-time data of blood, thereby limiting the emergency response capabilities of staff.

[0020] To this end, an embodiment of the present invention provides a blood transport method that can ensure the security of the transmission of blood information and related information of the transport box, so that staff can perform emergency response processing.

[0021] At least one embodiment of the present invention provides a blood transport method, including: high-frequency collection of the unlocking status of a blood transport box, blood storage bag information, the temperature inside the blood transport box, and positioning data, and transmitting the encrypted data to a cloud platform via 5G, and in the absence of a 5G signal, transmitting the encrypted data to the cloud platform via a Beidou short message module, and the cloud platform reversely decrypting the received data to obtain the real data of the blood transport box.

[0022] In the blood transfer method provided in the above-mentioned embodiment of the present invention, by encrypting the unlocking status of the blood transport box, blood storage bag information, temperature inside the blood transport box and positioning data, it can prevent them from being intercepted during the transmission process, and transmit the encrypted data to the cloud platform through the combination of 5G and Beidou short message module to ensure the continuity and timeliness of data transmission.

[0023] The present invention is described below by several specific embodiments. In order to keep the following description of the embodiments of the present invention clear and concise, the detailed description of known functions and known components may be omitted. When any component of the embodiments of the present invention appears in more than one accompanying drawings, the component may be represented by the same reference numeral in each of the accompanying drawings.

[0024] like Figure 1 As shown, Figure 1 This is a first flow chart of a blood transfer method provided by an embodiment of the present invention. An embodiment of the present invention provides a blood transfer method, including: high-frequency collection of the unlocking status of a blood transport box, blood storage bag information, temperature inside the blood transport box, and positioning data, encrypting the above data, transmitting the encrypted data to a cloud platform through a 5G communication module, and in the absence of a 5G signal, transmitting the encrypted data to the cloud platform through a Beidou short message module, and the cloud platform reversely decrypting the received data to obtain real data of the blood transport box.

[0025] A blood transport method provided by an embodiment of the present invention encrypts the unlocking status of a blood transport box, blood bag information, temperature inside the blood transport box, and positioning data collected in the case of emergency rescue and strategic resource scheduling, thereby avoiding the risk of being intercepted and leakage of data information of the blood bags in the box, thereby ensuring data security. The encrypted data is then transmitted to the cloud platform through a 5G communication module. In the absence of a 5G signal, the encrypted data is transmitted to the cloud platform through a Beidou short message module. With the help of 5G high-speed transmission technology or Beidou short message technology, the data of the blood transport box can be quickly uploaded to the cloud platform, ensuring real-time updating of information and avoiding the risk of being unable to make timely adjustments and take countermeasures due to delayed or lost information collection, thereby ensuring the safety and efficiency of blood transportation. Finally, the cloud platform reversely decrypts the received data to obtain the real data of the blood transport box, so that the staff can collect the real data of the blood transport box as soon as possible, thereby performing emergency response processing.

[0026] Specifically, in this embodiment, the unlocking state of the blood transport box, blood bag information, temperature inside the blood transport box, and positioning data are collected at high frequency, and the data are encrypted by high-frequency encryption, that is, the data is encrypted once every second. High-frequency encryption reduces the risk of data being cracked, and is synchronized with real-time monitoring during blood transportation, ensuring accurate recording and immediate response of blood status at any time point. In an emergency, the blood transport box can quickly encrypt the latest data to prevent key information leakage, while ensuring that the quality of the blood is not affected.

[0027] Specifically, the positioning data is collected in real time through the Beidou navigation system. Compared with the GPS navigation system currently used in blood transportation, the Beidou navigation system effectively solves the problem of data packet loss caused by GPS signal loss during transportation, thereby ensuring the continuity and stability of blood transfer box location monitoring. The Beidou system, with its wider coverage, demonstrates superior signal coverage and positioning accuracy. Compared with the GPS system, it significantly improves the reliability and accuracy of monitoring and prevents the leakage of sensitive information during blood transportation.

[0028] As an optional method, high-frequency collection of the unlocking status of the blood transport box, blood storage bag information, and temperature inside the blood transport box specifically includes: collecting its unlocking status through the electromagnetic lock used on the blood transport box, collecting blood storage bag information by reading the RFID electronic tag on the blood bag, collecting the internal temperature through the temperature sensor inside the blood transport box, sticking an RFID electronic tag with the blood bag data on the surface of the blood bag to be transported, and putting it into the blood transport box. The blood bag RFID electronic tag used is customized for each blood bag, and the data block of each RFID electronic tag stores the information of the blood bag. When the blood bag is put into the box, the blood transport box reads the RFID electronic tag data block information. During each unpacking operation, the blood transport box will automatically identify and read the RFID electronic tag on the blood bag.

[0029] Currently, there is a lack of monitoring of the power status of blood transport boxes, and there is a risk of sudden power outages during transportation, which may cause the transport box to be unable to open normally, affecting the safe delivery of blood.

[0030] Based on the above problems, in an embodiment of the present invention, the information that needs to be encrypted also includes the power level of the blood transport box. Real-time collection of the power level of the blood transport box can prevent the inability to collect accurate location information of the blood transport box due to power exhaustion, and prevent the temperature sensor from being unable to read the temperature inside the blood transport box in real time due to power interruption, thereby ensuring that the blood is stored within the specified temperature range and maintaining the quality and safety of the blood.

[0031] Specifically, the encryption processing method is AES encryption processing. AES encryption processing can ensure that sensitive data in the blood transportation process, such as positioning information and temperature data, is protected from unauthorized access and tampering. The fast encryption characteristics of AES ensure real-time encryption processing of key information such as the power, location and temperature of the blood transport box, without affecting the response time and data transmission efficiency of the blood transport box system.

[0032] Further, the AES encryption process specifies the use of CBC mode, PKCS5Padding padding, 128-bit key length and UTF-8 encoding. The present invention adopts CBC mode for AES encryption. Even if a ciphertext block is tampered with, it will affect the decryption of all subsequent ciphertext blocks, so that data tampering can be detected. PKCS5Padding can fill data blocks of different lengths as needed, which is suitable for encryption of variable-length data. The 128-bit key length maintains a high encryption and decryption speed while providing sufficient security, which is suitable for resource-constrained mobile devices. Due to the different language environments of the blood transport box and the cloud platform, UTF-8 encoding is used. The blood transport method provided by the present invention supports a multi-language environment, so that the data transmitted by the blood transport box can be read by the cloud platform.

[0033] As a preferred method, the above data is encrypted by AES and then encoded by BASE64 before being transmitted to the cloud platform. The blood transport method provided by the present invention adopts BASE64 encoding to ensure that the encrypted data can be seamlessly transmitted between different systems and protocols, which is crucial for the various communication channels that may be involved in the blood transport process. In addition, through BASE64 encoding, binary data compatibility problems that may occur during the transmission process are effectively avoided, ensuring the integrity of blood transport information. BASE64 itself does not provide encryption function, but it can be used as an additional layer to hide data content and provide additional security for blood transport information.

[0034] As a specific implementation method, Figure 2 As shown, Figure 2 This is a second flow chart of a blood transfer method provided by an embodiment of the present invention. The embodiment of the present invention provides a blood transfer method, including:

[0035] S1. Use a dedicated NFC card to open the blood transport box. The dedicated NFC card is specially equipped for the transporter and used as an administrator card to ensure that only the authorized transporter can unlock the blood transport box;

[0036] S2, attaching an RFID electronic tag with the blood bag data to the surface of the blood bag to be transported, and placing it in a blood transport box. The blood bag RFID electronic tag used is customized for each blood bag, and the data block of each RFID electronic tag stores the blood bag information;

[0037] S3. When the blood bag is put into the box, the blood transport box reads the RFID electronic tag data block information. At each unpacking operation, the blood transport box will automatically identify and read the RFID electronic tag on the blood bag. The ultra-high frequency radio frequency identification RFID technology used to read the RFID tag information of the blood bag is an automatic identification technology based on wireless communication. It can realize the accurate identification and management of the target object by automatically identifying the tag. The ultra-high frequency RFID electronic tag attached to the blood bag has obvious advantages over other frequency band tags: it can identify high-speed moving objects and can read multiple tags at the same time; it has strong penetration and anti-interference capabilities, and can work stably in harsh environments; at the same time, it also has high security and confidentiality, is reusable, and has a large data storage capacity. When the blood bag is placed in the blood transport box, the system can automatically read the blood bag information, thereby realizing real-time monitoring of the blood bag, ensuring the continuity and accuracy of monitoring, and monitoring whether the blood bag is illegally taken out or replaced during the blood transportation process, thereby creating safety hazards and regulatory blind spots;

[0038] S4. During the transportation of the blood transport box, the power monitoring module monitors the power of the blood transport box in real time, effectively preventing problems such as loss of transport box data and inability to unlock due to power exhaustion during transportation, ensuring the continuity and safety of the blood transportation process, thereby ensuring that blood can be delivered safely and timely;

[0039] S5. The temperature sensor in the blood transport box monitors the temperature in the box;

[0040] S6. Beidou navigation system in the blood transport box locates the position of the blood transport box in real time;

[0041] S7, every 1 second, the blood transport box performs AES encryption processing on the unlocking status of the blood transport box, the blood bag RFID tag information, the temperature inside the blood transport box, the power of the blood transport box, and the Beidou positioning data;

[0042] S8. The encrypted data is transmitted to the cloud platform via 5G. In the absence of 5G signals, the blood transport box transmits the encrypted data to the cloud platform via the Beidou short message module;

[0043] S9, the cloud platform performs AES reverse decryption on the received data to obtain the real data of the blood box;

[0044] The LCD screen of the blood transport box displays the data inside the box in real time.

[0045] The above inventions are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
