Description

Technical Field

[0001] Embodiments of the present disclosure relate to the field of computer technology, and in particular to a method, system, and device for transmitting vital sign data. Background Art

[0002] In current ward nursing work, monitors are widely used to monitor patients' vital signs (such as blood pressure and heart rate) in real time. However, patients often require multiple types of monitors to collect different vital sign data, making it difficult to synchronize these data in a timely manner. Furthermore, the disparity between the number of patients and the number of medical staff is significant. Therefore, conventional ward rounds make it difficult to effectively detect and treat patients with sudden abnormalities.

[0010] In a fifth aspect, some embodiments of the present disclosure provide a computer-readable medium having a computer program stored thereon, wherein when the program is executed by a processor, the method described in any implementation of the first aspect above is implemented.

[0011] The above-described embodiments of the present disclosure have the following beneficial effects: Through the vital sign data transmission methods of some embodiments of the present disclosure, timely synchronization of vital sign data collected by different types of monitors is achieved, enabling medical staff to remotely analyze patient vital sign data and promptly locate the patient's location when abnormalities occur, thereby effectively identifying and treating abnormal patients. Specifically, patients often require multiple types of monitors to collect different vital sign data. Different monitors have different hardware characteristics, making modification of existing monitors extremely difficult. Alternatively, purchasing a similar monitor with data synchronization capabilities also incurs significant purchase and equipment replacement costs. Therefore, the vital sign data transmission methods of some embodiments of the present disclosure first perform multi-source protocol data decoding on a read vital sign data set by a vital sign monitoring device to obtain a decoded vital sign data set. The vital sign monitoring device reads vital sign data collected by at least one monitor via a wired connection, where the at least one monitor uses different protocols to collect vital sign data for the same patient. In practice, considering the difficulty of retrofitting existing monitors, the present disclosure utilizes an external vital sign monitoring device to uniformly collect signals from multiple monitors corresponding to a single patient. Furthermore, given the varying signal protocols of different monitors, the vital sign monitoring device utilizes synchronous acquisition and multi-protocol decoding to obtain vital sign data collected by different types of monitors. Next, the decoded vital sign data set is uniformly encoded by the vital sign monitoring device to obtain an encoded vital sign data set. Next, in response to the vital sign monitoring device adopting a wireless transmission mode, a target router performs a non-sensing authentication on the vital sign monitoring device, wherein the vital sign monitoring device is within the signal range of the target router. The wireless transmission mode reduces the cost of large-scale wired wiring and line modification. Furthermore, vital sign monitors often require frequent movement (for example, after patient A is discharged from the hospital, the vital sign monitor used on patient A may need to be used on patient B). Therefore, vital sign monitoring devices also need to be moved between different wireless network environments, making conventional authentication methods complex. Therefore, the non-sensing authentication method ensures automatic networking and data transmission, regardless of changes in the wireless network environment. Furthermore, in response to successful authentication and the target mobile terminal being within the signal range of the target router, the encoded vital sign data set is transmitted to the target mobile terminal via the target router in a point-to-point transmission manner, wherein the target mobile terminal is device-bound to the at least one monitor. This point-to-point transmission avoids the time consuming process of transmitting data to the server and then forwarding it to the target mobile terminal, significantly ensuring the timeliness of data transmission, particularly for vital sign data that changes in real time.Finally, in response to the successful transmission, the vital sign status recognition model embedded in the above-mentioned target mobile terminal is used to identify the vital sign status according to the above-mentioned encoded vital sign data set to generate the vital sign status. By embedding the vital sign status recognition model into the target mobile terminal, the edge layout of the model is realized, which can further reduce the data processing pressure of the server. At the same time, for vital sign data that need to be processed in a timely manner, the time consumption in the process of transmitting the data back to the server can be further reduced. In this way, the vital sign data collected by different types of monitors can be synchronized in a timely manner, so that medical staff can remotely analyze the patient's vital sign data and locate the patient's position in time when the patient is abnormal, so as to achieve effective discovery and treatment of abnormal patients.

[0028] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0029] refer to Figure 1 , shows a process 100 of some embodiments of the method for transmitting vital signs data according to the present disclosure. The method for transmitting vital signs data includes the following steps:

[0030] Step 101 : A vital sign monitoring device is used to perform multi-source protocol data decoding on a read vital sign data set to obtain a decoded vital sign data set.

[0031] In some embodiments, an entity executing a vital sign data transmission method (e.g., a computing device) can, through a vital sign monitoring device, perform multi-source protocol data decoding on a read vital sign data set to obtain a decoded vital sign data set. The vital sign monitoring device reads vital sign data collected by at least one patient monitor using a wired connection. At least one of the monitors utilizes different protocols and is used to collect vital sign data from the same patient. At least one of the monitors utilizes at least one data encoding protocol. At least one of the monitors includes an Ethernet interface. The vital sign data can represent any of the patient's blood pressure, heart rate, blood oxygen saturation, heart rate variability, pulse, and respiratory rate data. The use of a wired connection between the monitor and the vital sign monitoring device is problematic because, when a large number of monitors are used, wireless connections can lead to channel interference. Furthermore, some monitors lack wireless data transmission capabilities, and modification is costly.

[0032] For example, see Figure 2 A front view of the vital signs monitoring device shown, and Figure 3 The rear view of the vital signs monitoring device shown in the figure includes: a shell 1, 10 first Ethernet interfaces 2 (a set of first Ethernet interfaces), a second Ethernet interface 3, and a wireless signal transceiver 4. Specifically, the first Ethernet interface 2, the second Ethernet interface 3, and the wireless signal transceiver 4 are all provided with indicator lights to indicate the working status of the interfaces and the transceivers. Specifically, in the wireless transmission mode, the vital signs monitoring device transmits data with the target router through the wireless signal transceiver 4. In the wired transmission mode, the vital signs monitoring device transmits data through the network optical cable provided between the second Ethernet interface 2 and the target router; the monitor supplies power to the vital signs monitoring device through PoE. Specifically, among the 10 first Ethernet interfaces 2, there is one first Ethernet interface that can be powered by PoE.

[0033] In addition, the vital signs monitoring device also includes: a decoding module, an encoding module and an MCU module. The decoding module includes: a hard decoder and a soft decoder. The hard decoder includes: a signal preprocessing unit and N hard decoding units. The signal preprocessing unit is used to segment the vital signs data, perform two-dimensional expansion on the segmented vital signs data, and perform sequence restoration on the data decoded by the hard decoding unit. The N hard decoding units are connected to the signal preprocessing unit in parallel. The hard decoding unit is used to decode the segmented vital signs data assigned by the signal preprocessing unit. The hard decoding unit can be a decoding unit equipped with a hardware decoding circuit according to the encoding and decoding method corresponding to the monitor. For details, see Figure 4The figure shows the relationship between the components of the vital sign monitoring device, in which 10 first Ethernet interfaces 2 (a set of first Ethernet interfaces) are connected to the MCU module 5 via a wired connection. The MCU module 5 is used to perform data scheduling and issue control instructions. There is bidirectional interaction between the MCU module 5 and the decoding module 6. There is bidirectional interaction between the MCU module 5 and the encoding module 7. The MCU module 5 is connected to the second Ethernet interface 4 by wire. Furthermore, the decoding module 6 includes: a hard decoder 8 and a soft decoder 9. Specifically, the soft decoder 9 can use the CPU resources in the MCU module 5 to implement soft decoding of data. The hard decoder 8 includes: a signal preprocessing unit 10 and N hard decoding units 11. The N hard decoding units 11 perform data interaction with the signal preprocessing unit 10 in parallel.

[0034] It should be noted that the computing device described above can be either hardware or software. When the computing device is hardware, it can be implemented as a single terminal device (vital sign monitoring device). When the computing device is software, it can be installed in the hardware devices listed above. It can be implemented as a single software or software module. This is not specifically limited here.

[0035] In some optional implementations of some embodiments, the execution subject performs multi-source protocol data decoding on the read vital sign data set through a vital sign monitoring device to obtain a decoded vital sign data set, including:

[0036] In the first step, for each vital sign data in the above vital sign data set, the following decoding steps are performed:

[0037] The first sub-step is to parse the encoding protocol type corresponding to the above vital signs data.

[0038] In practice, different vital sign devices use different data encoding methods for the collected vital sign data. Therefore, by parsing the header file of the data packet, you can parse the protocol identifier that identifies the encoding protocol type, and then map it to the encoding protocol type corresponding to the vital sign data.

[0039] In the second sub-step, in response to parsing the above-mentioned coding protocol type and the decoding module included in the vital signs monitoring device including a hard decoder for the above-mentioned protocol type, the above-mentioned vital signs data are decoded by the hard decoder corresponding to the above-mentioned protocol type to obtain the decoded vital signs data corresponding to the above-mentioned vital signs data in the above-mentioned decoded vital signs data set.

[0040] The hardware decoder includes a signal preprocessing unit and N hard decoding units. The signal preprocessing unit is used to segment vital sign data, perform two-dimensional expansion of the segmented vital sign data, and perform sequence restoration on the data decoded by the hard decoding unit. The N hard decoding units are connected in parallel to the signal preprocessing unit and are used to decode the segmented vital sign data assigned by the signal preprocessing unit. The hardware decoder can effectively alleviate CPU computing pressure, especially for low-power MCU modules. It can also further reduce power consumption and heat generation.

[0041] As an example, the vital sign data may represent heart rate data. Figure 5 The following is a schematic diagram of the process for generating decoded vital sign data. The vital sign data 501 may be a 1×L sequence of heart rate values. The heart rate values ​​in the vital sign data 501 are encoded using the encoding protocol specified by the vital sign instrument and therefore cannot be directly read. L represents the sequence length. The signal preprocessing unit 10 expands the 1×L sequence of heart rate values ​​(vital sign data) into N H×M two-dimensional heart rate value matrices 502. N×H×M ≥ L. That is, when the matrix is ​​not divisible, the two-dimensional expansion is achieved by padding with zeros. The N H×M two-dimensional heart rate value matrices 502 correspond one-to-one to the N hard decoding units 11. These N hard decoding units 11 can decode the data in parallel to obtain N decoded heart rate value sequences 503. Finally, the signal preprocessing unit 10 concatenates the N decoded heart rate value sequences 503 in time sequence to obtain decoded vital sign data 504 corresponding to the vital sign data 501.

[0042] The third sub-step is, in response to parsing the above-mentioned encoding protocol type and the decoding module not including a hard decoder for the above-mentioned protocol type, decoding the above-mentioned vital signs data through the soft decoder included in the above-mentioned decoding module to obtain the decoded vital signs data corresponding to the above-mentioned vital signs data in the above-mentioned decoded vital signs data set.

[0043] In practice, the soft decoder uses the CPU resources in the MCU module to decode the vital signs data according to the decoding algorithm corresponding to the encoding protocol type. Considering that some encoding protocols are used less frequently, designing a dedicated hardware decoder would be inefficient. Therefore, soft decoding is implemented using the CPU resources in the MCU module to ensure the robustness of the decoding module.

[0044] Step 102: uniformly encode the decoded vital sign data set by a vital sign monitoring device to obtain an encoded vital sign data set.

[0045] In some embodiments, the execution entity may uniformly encode the decoded vital sign data set through a vital sign monitoring device to obtain an encoded vital sign data set. In practice, the execution entity may employ the HL7 (Health Level Seven) encoding protocol to uniformly encode each decoded vital sign data in the decoded vital sign data set to obtain an encoded vital sign data set.

[0046] In some optional implementations of some embodiments, the execution subject uniformly encodes the decoded vital sign data set through the vital sign monitoring device to obtain an encoded vital sign data set, including:

[0047] In the first step, for each decoded vital sign data in the decoded vital sign data set, the following encoding steps are performed:

[0048] The first sub-step is to determine the first-order derivative value sequence corresponding to the decoded vital sign data.

[0049] In practice, since the decoded vital sign data is still a one-dimensional time series, the forward difference method can be used to calculate the first-order derivative value sequence corresponding to the decoded vital sign data.

[0050] For example, the decoded vital sign data represents the decoded heart rate data. The decoded vital sign data may be [89, 90, 92, 120, 134, 110, 100, 80]. The corresponding first-order derivative value sequence may be [1, 2, 28, 14, -24, -10, -20].

[0051] The second sub-step is to generate the initial segmentation tree.

[0052] The first-order derivative value sequence corresponds to the root node of the initial segmentation tree. Specifically, the tree node stores the starting position and ending position of the (first-order derivative value) sequence in the decoded vital sign data. For example, see Figure 6 In the updated segmentation tree shown, the decoded vital sign data 504 may be [89, 90, 92, 120, 134, 110, 100, 80]. The root node in the updated segmentation tree corresponds to [1, 2, 28, 14, -24, -10, -20] (a sequence of first-order derivative values). The root node then stores [starting position: 1, ending position: 8].

[0053] The third sub-step is to perform the following sampling area determination steps based on the first-order derivative value sequence:

[0054] Step 1: Split the first-order derivative value sequence into the first derivative value sequence and the second derivative value sequence.

[0055] In practice, let the number of first-order derivative values ​​in the first-order derivative value sequence be Num. When Num is an even number, the number of first-order derivative values ​​in the first-order derivative value sequence is Num / 2. The number of first-order derivative values ​​in the first-order derivative value sequence is Num / 2. When Num is an odd number, the number of first-order derivative values ​​in the first-order derivative value sequence is Num / 2+1. The number of first-order derivative values ​​in the first-order derivative value sequence is Num / 2. When Num is an odd number, Num / 2 is rounded down.

[0056] As an example, the first derivative value sequence is [1, 2, 28, 14, -24, -10, -20]. The first derivative value sequence is [1, 2, 28, 14]. The second derivative value sequence is [-24, -10, -20].

[0057] Step 2: Update the initial segmentation tree according to the first derivative value sequence and the second derivative value sequence to obtain an updated segmentation tree.

[0058] For example, see further Figure 6 , the root node in the updated partition tree includes two leaf nodes. Both leaf nodes are connected to the root node. Among them, the left leaf node corresponds to the first derivative value sequence [1, 2, 28, 14]. The left leaf node stores [starting position: 1, ending position: 5]. The right leaf node corresponds to the second derivative value sequence [-24, -10, -20]. The right leaf node stores [starting position: 5, ending position: 8].

[0059] Step 3: Determine the standard deviations corresponding to the first derivative value sequence, the first derivative value sequence, and the second derivative value sequence, respectively, to obtain the first standard deviation, the second standard deviation, and the third standard deviation.

[0060] In practice, the standard deviation formula can be used to determine the first, second, and third standard deviations. For example, the standard deviation (first standard deviation) for [1, 2, 28, 14, -24, -10, -20] is approximately 17.14. The standard deviation (second standard deviation) for [1, 2, 28, 14] is approximately 10.91. The standard deviation for [-24, -10, -20] is approximately 5.89.

[0061] Step 4: In response to the second standard deviation being less than or equal to the first standard deviation and the third standard deviation being less than or equal to the first standard deviation, or the tree depth of the updated segmentation tree being greater than or equal to the preset tree depth, the above-mentioned sampling area determination step is terminated.

[0062] In practice, since standard deviation calculation is required, a preset tree depth constraint is set to avoid the problem of large data calculation amount caused by excessive tree depth.

[0063] Fourth sub-step: In response to the second standard deviation being greater than the first standard deviation, the first derivative value sequence is used as a first-order derivative value sequence, and the above-mentioned sampling area determination step is performed again.

[0064] Fifth sub-step: In response to the third standard deviation being greater than the first standard deviation, the second derivative value sequence is used as a section of the derivative value sequence, and the above-mentioned sampling area determination step is performed again.

[0065] The sixth sub-step is to segment the decoded vital sign data according to the numerical sequence boundaries corresponding to the leaf nodes in the updated segmentation tree to obtain sub-decoded vital sign data sequences.

[0066] For example, see Figure 6 The updated segmentation tree shown in the figure shows that the decoded vital sign data can be segmented at position 5 to obtain sub-decoded vital sign data sequences. The obtained sub-decoded vital sign data sequences are [89, 90, 92, 120, 130] and [130, 110, 100, 80] respectively.

[0067] The seventh sub-step is to sample the sub-decoded vital sign data in the sub-decoded vital sign data sequence according to the node level number corresponding to the leaf node in the updated segmentation tree to obtain a sampled vital sign data sequence.

[0068] The sampling frequency of data sampling is positively correlated with the number of node layers. Specifically, the deeper the node layer a leaf node is located, the higher the corresponding sampling frequency. In practice, a mapping table between node layers and sampling frequencies can be constructed, and the sampling frequency corresponding to each leaf node can be determined by table lookup.

[0069] For example, see Figure 7 Another tree structure diagram of the updated segmentation tree shown in FIG. Figure 7 The updated split tree shown in the figure has a tree depth of 4 and split positions of 5, 20, and 60. Figure 7 The updated segmentation tree shown in the figure shows that the fluctuation is mainly observed in the rear part of the decoded vital sign data. Therefore, the sampling rate of the data at position [1,5] in the decoded vital sign data is less than the sampling rate of the data at position [5,20] in the decoded vital sign data. The sampling rate of the data at position [20,60] in the decoded vital sign data is equal to the sampling rate of the data at position [60,N] in the decoded vital sign data.

[0070] In the eighth sub-step, a segmentation marker is inserted between every two pieces of sampled vital sign data in the sampled vital sign data sequence to obtain encoded vital sign data in the encoded vital sign data set corresponding to the decoded vital sign data.

[0071] The segmentation identifier is a triplet, including: an end character corresponding to the previously sampled vital sign data, a check character corresponding to the previously sampled vital sign data, and a sampling frequency corresponding to the next sampled vital sign data. The check character may be a CRC (Cyclic Redundancy Check) check character.

[0072] The above-mentioned content of "in some optional implementation methods of some embodiments" is a core invention point of the present disclosure. By combining the standard deviation, the volatility of the encoded vital signs data is characterized. In this way, combined with the volatility of the data, the encoded vital signs data is variable-length segmented and encoded from a finer scale. Compared with the traditional fixed-frequency sampling method, the attention paid to high-volatility data is greatly improved, and the sensitivity to low-volatility data is reduced. At the same time, by setting the segmentation mark, the sampled vital signs data is re-encoded, which realizes the variable-length encoding of the data and facilitates the subsequent data recovery. In this way, more efficient encoding of the data is achieved.

[0073] In some optional implementations of some embodiments, after the execution subject uniformly encodes the decoded vital sign data set through the vital sign monitoring device to obtain the encoded vital sign data set, the method further includes:

[0074] The first step is to transmit the encoded vital signs data set to the target router in a wired transmission mode through the second Ethernet interface included in the vital signs monitoring device in a wired transmission manner in response to the transmission mode of the vital signs monitoring device, and to transmit the encoded vital signs data set to the cloud server through the target router in a wireless transmission manner.

[0075] In the second step, in response to the successful transmission, it is determined whether the target mobile terminal is in an online state.

[0076] In practice, the target server may send status verification information to the target mobile terminal, and when receipt information is received, it indicates that the target mobile terminal is in an online state.

[0077] In the third step, in response to the target mobile terminal being in an online state, determining whether a target socket connection exists in the socket connection pool.

[0078] Among them, the socket connection pool is used to cache socket connections in the connection-enabled state. The socket connection pool uses a timed connection verification method to verify the connection status of the socket connection and initialize the socket connection when the socket connection is in a non-communication state. The target socket connection is a two-way communication connection set between the target mobile terminal and the cloud server. The socket connection in the socket connection pool adopts the TCP protocol. By initializing the socket connection in the non-communication state, repeated verification of subsequent socket connections is avoided. The socket connection can be reused without updating the destination address and source address related information, thereby improving the efficiency of the socket connection. In addition, compared with the UDP (User Datagram Protocol) protocol, the TCP (Transmission Control Protocol) protocol is adopted to ensure the security of data transmission.

[0079] In the fourth step, in response to the non-existence, a socket connection in an initialized state is screened out from the socket connection pool, and a communication address corresponding to the target mobile terminal is allocated as the target socket connection.

[0080] Step 5: In response to the existence, the encoded vital sign data set is transmitted to the target mobile terminal through the target socket connection.

[0081] Step 103 : In response to the transmission mode of the vital sign monitoring device being the wireless transmission mode, a non-contact identity authentication is performed on the vital sign monitoring device through the target router.

[0082] In some embodiments, the execution subject may perform contactless identity verification on the vital sign monitoring device through a target router in response to the fact that the transmission mode of the vital sign monitoring device is a wireless transmission mode.

[0083] Optionally, the target router caches an identity authentication table, which includes: a first identity identifier, a first communication address, a token verification code, a second identity identifier, and a second communication address, wherein the first identity identifier is the identity identifier of the vital signs monitoring device, the first communication address is the communication address corresponding to the vital signs monitoring device, the token verification code is used for contactless identity authentication and identity identifier uniqueness verification of the vital signs monitoring device, the second identity identifier is the identity identifier of the target mobile terminal, and the second communication address is the communication address of the target mobile terminal.

[0084] In some optional implementations of some embodiments, in response to the transmission mode of the vital sign monitoring device being a wireless transmission mode, the execution subject performs a non-sensing identity verification on the vital sign monitoring device through a target router, including:

[0085] The first step is to determine whether the identity identifier corresponding to the above-mentioned vital sign monitoring device exists in the identity verification table.

[0086] In practice, the target router may scan the identity authentication table to determine whether the identity identifier corresponding to the vital sign monitoring device exists in the identity authentication table.

[0087] In the second step, in response to the existence, the target router initiates identity token verification for the vital sign monitoring device according to the token verification code included in the identity verification table.

[0088] The identity token is regularly updated and distributed to the vital sign monitoring device by the cloud server. In practice, the legitimacy of the identity token of the vital sign monitoring device can be verified using the token verification code. Specifically, a verification code corresponding to the identity token can be generated using a hash algorithm. By comparing the verification code with the token verification code, the legitimacy of the identity token can be determined.

[0089] The third step is to generate a verification result indicating that the vital sign monitoring device has passed the identity authentication in response to the verification being successful.

[0090] Step 104 : In response to the identity authentication being passed and the target mobile terminal being within the signal range of the target router, the encoded vital sign data set is transmitted to the target mobile terminal via the target router in a point-to-point transmission manner.

[0091] In some embodiments, the execution entity may transmit the encoded vital sign data set to the target mobile terminal via the target router in a point-to-point transmission manner in response to successful authentication and the target mobile terminal being within the signal range of the target router. The target mobile terminal and the at least one monitor are device-bound. In practice, using point-to-point communication allows data to be transmitted directly to the target mobile terminal without being forwarded to a cloud server, thereby ensuring efficient data transmission.

[0092] For example, see Figure 8 The data collection and transmission process is shown in Figure 1. A vital sign collection device 802 collects and processes the vital sign data collected by at least one monitor 801 via a wired connection. The device then transmits the encoded vital sign data set to a target mobile terminal 804 via a target router 803 in a point-to-point manner.

[0093] Step 105 , in response to the successful transmission, a vital sign state recognition model embedded in the target mobile terminal is used to perform vital sign state recognition based on the encoded vital sign data set to generate a vital sign state.

[0094] In some embodiments, the above-mentioned execution subject can, in response to successful transmission, perform vital sign status recognition based on the encoded vital sign data set through the vital sign status recognition model embedded in the target mobile terminal to generate a vital sign status. In practice, considering the limited computing power of the target mobile terminal, a lightweight vital sign status recognition model can be adopted and embedded in the target mobile terminal. The training of the vital sign status recognition model can be executed on the cloud server and updated to the target mobile terminal in a regular manner through distribution. Specifically, since the encoded vital sign data set has obvious time series characteristics, the vital sign status recognition model can use the LightRNN model as the backbone network, and connect multiple classifiers, with the encoded vital sign data set as input, and output the vital sign status.

[0095] The above-described embodiments of the present disclosure have the following beneficial effects: Through the vital sign data transmission methods of some embodiments of the present disclosure, timely synchronization of vital sign data collected by different types of monitors is achieved, enabling medical staff to remotely analyze patient vital sign data and promptly locate the patient's location when abnormalities occur, thereby effectively identifying and treating abnormal patients. Specifically, patients often require multiple types of monitors to collect different vital sign data. Different monitors have different hardware characteristics, making modification of existing monitors extremely difficult. Alternatively, purchasing a similar monitor with data synchronization capabilities also incurs significant purchase and equipment replacement costs. Therefore, the vital sign data transmission methods of some embodiments of the present disclosure first perform multi-source protocol data decoding on a read vital sign data set by a vital sign monitoring device to obtain a decoded vital sign data set. The vital sign monitoring device reads vital sign data collected by at least one monitor via a wired connection, where the at least one monitor uses different protocols to collect vital sign data for the same patient. In practice, considering the difficulty of retrofitting existing monitors, the present disclosure utilizes an external vital sign monitoring device to uniformly collect signals from multiple monitors corresponding to a single patient. Furthermore, given the varying signal protocols of different monitors, the vital sign monitoring device utilizes synchronous acquisition and multi-protocol decoding to obtain vital sign data collected by different types of monitors. Next, the decoded vital sign data set is uniformly encoded by the vital sign monitoring device to obtain an encoded vital sign data set. Next, in response to the vital sign monitoring device adopting a wireless transmission mode, a target router performs a non-sensing authentication on the vital sign monitoring device, wherein the vital sign monitoring device is within the signal range of the target router. The wireless transmission mode reduces the cost of large-scale wired wiring and line modification. Furthermore, vital sign monitors often require frequent movement (for example, after patient A is discharged from the hospital, the vital sign monitor used on patient A may need to be used on patient B). Therefore, vital sign monitoring devices also need to be moved between different wireless network environments, making conventional authentication methods complex. Therefore, the non-sensing authentication method ensures automatic networking and data transmission, regardless of changes in the wireless network environment. Furthermore, in response to successful authentication and the target mobile terminal being within the signal range of the target router, the encoded vital sign data set is transmitted to the target mobile terminal via the target router in a point-to-point transmission manner, wherein the target mobile terminal is device-bound to the at least one monitor. This point-to-point transmission avoids the time consuming process of transmitting data to the server and then forwarding it to the target mobile terminal, significantly ensuring the timeliness of data transmission, particularly for vital sign data that changes in real time.Finally, in response to the successful transmission, the vital sign status recognition model embedded in the above-mentioned target mobile terminal is used to identify the vital sign status according to the above-mentioned encoded vital sign data set to generate the vital sign status. By embedding the vital sign status recognition model into the target mobile terminal, the edge layout of the model is realized, which can further reduce the data processing pressure of the server. At the same time, for vital sign data that need to be processed in a timely manner, the time consumption in the process of transmitting the data back to the server can be further reduced. In this way, the vital sign data collected by different types of monitors can be synchronized in a timely manner, so that medical staff can remotely analyze the patient's vital sign data and locate the patient's position in time when the patient is abnormal, so as to achieve effective discovery and treatment of abnormal patients.
