During the blood collection stage, historical blood information in the operating blockchain is retrieved, an RFID tag of the blood is constructed based on the historical blood information, current blood information of the blood is generated based on the RFID tag, and the current blood information is uploaded to the operating blockchain.

[0033] In the embodiment of the present invention, the RFID tag refers to a blood identification code, which is uniquely determined by the blood bag number and the blood product.

[0034] Furthermore, the embodiment of the present invention constructs an RFID tag of the blood according to the historical blood information, so as to avoid conflicts between the newly generated RFID tag and the RFID tag in the historical blood information.

[0041] Based on the signal propagation distance, a first storage address of the blood is determined.

[0042] Among them, the expandable positioning area refers to the hospital area. Since GPS positioning can only locate the entire area of ​​the hospital and cannot locate the positions of various departments within the hospital, the expandable positioning area is set. The non-expandable positioning area refers to the area without expandable positioning inside, such as traffic lights, parking lots, etc., which can be accurately located using GPS positioning. Furthermore, the channel state information is referred to as CSI for short, which refers to a type of information used to describe the characteristics and quality of a wireless channel in a wireless communication system. It provides information about the time-varying characteristics of the channel, including fading, multipath propagation, interference, etc. CSI contains information on The following aspects of information: Delay: describes the time delay of signal transmission from the transmitter to the receiver; Fading: measures the degree to which the signal strength weakens with increasing distance, that is, the fading characteristics of the signal; Multipath propagation: describes the situation where the signal reaches the receiver through different paths, including direct paths and reflected paths; Spectral efficiency: used to measure how many bits of information can be transmitted under a given bandwidth; Interference: describes the influence of other irrelevant signals on the current signal, such as co-channel interference or heterodyne interference; Noise: describes the random noise introduced by the environment and the receiver itself.

The neural network refers to a convolutional neural network model for domain adaptation, and its structure includes the following main components: Convolutional Layers: The convolutional layer is the basic component of the DA-CNN model.

In each convolutional layer, a series of convolution kernels perform convolution operations on the input and introduce nonlinearity through activation functions. These convolutional layers can extract high-dimensional features from the original image. Pooling Layers: The pooling layer is used to reduce the spatial size of the feature map while retaining the most important features. Domain Adaptation Layer: This layer is a key component of the DA-CNN model and is used to achieve domain adaptation. It eliminates domain differences by aligning the features of the source domain and the target domain. The domain adaptation layer usually uses some adversarial training methods, such as Domain Adversarial Neural Network (DANN) or Maximum Mean Difference (RMSD). Discrepancy, MMD), etc. Fully Connected Layers: The fully connected layer is used to map the output features of the convolutional layer to the space of the predicted target.

[0044] Optionally, the process of determining the first storage address of the blood based on the signal propagation distance is: after determining the propagation path of the signal between multiple transmitting antennas and multiple receiving antennas, the positioning of the blood between the multiple transmitting antennas and multiple receiving antennas can be determined.

[0045] It should be noted that the process of using the storage address to update the current blood information in the operating blockchain to obtain the first updated blockchain is: adding the storage address in the block space.

[0046] S4. In the blood delivery stage, the person delivering the blood is identified, the integrity of the blood is verified at the delivery person, and based on the integrity, the first updated blockchain is updated to obtain a second updated blockchain.

[0047] In the embodiment of the present invention, the delivery personnel include doctors from different departments, nurses from different departments and other personnel types.

[0048] Furthermore, the embodiment of the present invention verifies the integrity of the blood at the delivery person so that when the RFID tag is damaged, other methods can be used to detect the RFID tag, thereby ensuring successful blood number identification and timely detecting the blood volume when the blood volume changes, thereby improving recording accuracy.

[0049] Further, the checking the integrity of the blood at the delivery person includes: detecting the RFID tag of the blood at the delivery person; querying whether there is a target RFID tag consistent with the RFID tag in the first updated blockchain; when there is no target RFID tag consistent with the RFID tag in the first updated blockchain, determining the first integrity of the blood; when there is a target RFID tag consistent with the RFID tag in the first updated blockchain, calculating the blood weight of the blood using the following formula:

[0050] in, represents the blood weight, represents the pre-calibrated area coefficient, represents the projected area of ​​the blood, , represents a constant parameter; Query whether the weight of the blood is consistent with the weight of the blood product in the first updated blockchain, and when the weight of the blood is not consistent with the weight of the blood product in the first updated blockchain, determine the second integrity of the blood; when the weight of the blood is consistent with the weight of the blood product in the first updated blockchain, determine the third integrity of the blood.

[0051] It should be noted that the process of calculating the blood weight of the blood collects an image of the blood bag, uses image recognition technology to identify the projected area of ​​the blood in the image, and calculates the blood weight using trained area coefficients and constant parameters.

[0052] Furthermore, based on the integrity, the first updated blockchain is updated to obtain a second updated blockchain, including: identifying the current delivery person of the blood; querying the block space of the current delivery person in the first updated blockchain; when the integrity is the first integrity, querying the neighborhood RFID tag of the RFID tag; using the neighborhood RFID tag to identify the first target RFID tag of the RFID tag in the first updated blockchain; based on the first target RFID tag, performing a block update in the block space of the current delivery person to obtain a first second updated blockchain; when the integrity is the second integrity, adding blood product weight data to the block space of the current delivery person to obtain a second second updated blockchain; when the integrity is the third integrity, no update operation is performed in the block space of the current delivery person to obtain a third second updated blockchain.

[0053] Among them, the neighborhood RFID tag refers to other RFID tags from the same batch as the current RFID tag. Furthermore, the process of using the neighborhood RFID tag to identify the first target RFID tag of the RFID tag in the first updated blockchain is: query the corresponding recorded RFID tag of each neighborhood RFID tag in the neighborhood RFID tag in the first updated blockchain respectively, so that the first target RFID tag that has no corresponding neighborhood RFID tag can be determined from the recorded RFID tags.

[0054] S5. During the blood use phase, the blood bag carrying the blood is recovered in the second updated blockchain to obtain the blood circulation result of the blood.

[0055] Optionally, the process of recovering the blood bag carrying the blood in the second updated blockchain to obtain the blood circulation result of the blood is: recording the destruction information of the blood bag in the block space corresponding to the blood usage stage, and the destruction information includes the original address information of the blood bag, storage information, destruction mark, empty blood bag quantity, etc.

[0056] It can be seen that the embodiment of the present invention divides the blood operation stage to divide the long chain of blood operation into multiple shorter chains, so as to refine the blood operation process in each short chain later. Furthermore, the embodiment of the present invention constructs the operation blockchain of the operation stage to replace the cold chain monitoring system with the blockchain to realize the full chain tracking of blood and increase the confidentiality and non-tamperability of blood data. Furthermore, the embodiment of the present invention constructs the RFID tag of the blood according to the historical blood information to avoid the conflict between the newly generated RFID tag and the RFID tag in the historical blood information. The embodiment of the present invention tracks the storage address of the blood to display the specific location of the blood in the hospital. Furthermore, the embodiment of the present invention verifies the integrity of the blood at the delivery personnel to detect the RFID tag by other methods when the RFID tag is damaged, ensures the successful identification of the blood number, and detects the blood volume in time when the blood volume changes, thereby improving the recording accuracy.
