[0024] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] An in-hospital intelligent medical consultation assistance system for the elderly includes a user management platform and a device terminal; the device terminal is provided with an intelligent medical consultation assistance module; the intelligent medical consultation assistance module includes: a camera unit scans the medical consultation code and quickly binds the patient's identity information; a sensor unit is connected to the storage unit and is used to collect the patient's heart rate, blood oxygen, and standing posture data in real time; a positioning unit is connected to the storage unit and periodically collects the patient's location information, and the communication module periodically sends the data collected by the storage unit to the user management platform; the communication module receives the text information sent by the user management platform in real time; the voice unit plays voice according to the text of the communication module to guide the patient to complete the medical consultation; the communication module sends emergency assistance information to the user management platform; and a touch screen is provided to allow users to conveniently operate functional applications. The user management platform is provided with: the platform obtains the vital signs and standing posture data of the monitored bound personnel, and reminds medical staff to handle after receiving abnormal data; the platform sends text to the communication module of the terminal device; the platform monitors the status of the bound personnel, and promptly reminds medical staff to handle after receiving emergency help information.

[0027] Among them, please refer to Figure 1 As shown, the device terminal is a scenario where medical guidance is required, such as a smart bracelet, a smart watch, a smart tablet and other device terminals.

[0028] Elderly users can scan their personal medical codes through device terminals to bind their identity information. After the user management platform obtains the personnel information, it automatically collects the business nodes of each stage of their medical treatment process.

[0029] When elderly users need to proceed to the next step of business, the user management platform automatically sends voice and text notifications to guide the users to complete the medical treatment.

[0030] The device terminal obtains the current user's location information in the hospital in real time, and automatically and accurately guides the user to the business location he needs to go to next.

[0031] The user management platform provides real-time reminders and notifications based on the current business status of the bound user, such as which department to go to, the current queue number, etc.

[0032] After binding a person, medical staff can view the current status of the bound person on the user management platform, including their precise location information, vital signs information, help status information, etc.

[0033] When the device terminal collects the user's vital data, medical staff can bind the person's vital data, including blood oxygen, heart rate, and standing status, on the user management platform. If abnormal data appears, the platform will also issue a prompt reminder.

[0034] When the bound user sends an emergency request through the device terminal, the user management platform will notify the medical staff on duty in real time and push the user's precise location information.

[0035] In the embodiments, as referenced Figure 2 As shown, when a user uses a device terminal, he or she first needs to perform identity authentication binding to complete the establishment of the user identity relationship.

[0036] After the user completes the binding, he can use the touch screen operating system software of the device terminal to help him complete the medical treatment.

[0037] Users can view functional modules by swiping left and right on the touch screen.

[0038] Users can view their heart rate, blood oxygen, and standing posture data by clicking on the vital signs monitoring function; click on emergency help to quickly initiate a rescue request to the hospital; click on the message notification to view the medical guidance instructions issued by the user management platform.

[0039] Since this system can collect authentication information and vital signs information sent by all equipment terminals, and analyze the collected big data on this basis, it can be used to guide and optimize daily work, meet the needs of operators for information guidance and intelligent analysis of personnel, areas and time using big data, help hospital staff to optimize resource allocation, and maintain and update the system in a timely and targeted manner, providing better support and service management for the front-end.

[0040] Embodiment 1:

[0041] Take the updating of the geographical location data of the elderly by the positioning unit of the present invention as an example.

[0042] like Figure 3As shown, the positioning unit includes a Bluetooth receiving device and a positioning device. The positioning unit receives a signal containing the location information of the Bluetooth beacon sent by the Bluetooth beacon within the activity range of the elderly through the Bluetooth receiving device. The signal is processed by the positioning device to determine the location of the elderly. The location information is sent to the service center platform through the communication module. The Bluetooth beacon includes multiple Bluetooth beacons deployed in the area where positioning is required and Bluetooth beacons already in public places.

[0043] According to a preferred embodiment, the positioning unit updates the geographical location of the elderly in the following manner:

[0044] When the elderly person holding the positioning unit enters the coverage of the Bluetooth beacon, the Bluetooth receiving device of the positioning unit receives the broadcast message sent by at least one Bluetooth beacon. The broadcast message sent by each Bluetooth beacon includes the location information and type of the Bluetooth beacon. The positioning device determines the location of the user device based on the RSSI of the broadcast message corresponding to each Bluetooth beacon received and the location information and type information of the Bluetooth beacon in the broadcast message.

[0045] According to a preferred embodiment, the distance formula is as follows:

[0046]

[0047] refer to Figure 3 Point A has coordinates (x1, S1), point B has coordinates (x2, C2), and point C has coordinates (x3, y3). The distances between the target point P and these three reference points are: d1 from A, d2 from B, and d3 from C. These three equations form a system of equations, and the goal is to solve (x, y). By expanding these equations and eliminating variables algebraically, two solutions are usually obtained, one of which is the true position of the target point. To simplify the solution process, it is usually necessary to first subtract two of the equations to eliminate one variable (such as y), then solve for another variable (such as x), and then substitute it into another equation to solve for the remaining variable.

[0048] For example:

[0049]

[0050] These two equations can be subtracted to eliminate the square term, and the linear relationship about x and y can be obtained, and then the coordinates of the target point can be obtained by substituting them into the solution. During the calculation process, RSSI measurement will be affected by obstacles such as walls and furniture, resulting in signal attenuation and measurement errors.

[0051] Noise interference can be reduced by filtering algorithms (such as Kalman filtering). At the same time, the signal may be reflected or refracted, resulting in multipath effects. Correction can be made by modeling the environment or combining multiple sensors (such as accelerometers, gyroscopes).

[0052] Embodiment 2:

[0053] Take the fall detection unit of the present invention updating the motion data of the elderly as an example.

[0054] The fall detection unit includes an acceleration sensor, a gyroscope sensor and a microprocessor. The fall detection unit detects the acceleration value and angular velocity value of the elderly in the X-axis, Y-axis and Z-axis directions through the acceleration sensor and the gyroscope sensor and sends the acceleration value and angular velocity value to the microprocessor for data processing, and then the fall detection unit sends the processed data to the service center platform through the communication module.

[0055] Falls are usually accompanied by the following typical characteristics: Sudden change in acceleration: When falling, the human body will experience a rapid change in acceleration, especially in the vertical direction (for example, from standing to falling). Sudden change in posture: Falling can cause a significant change in body posture, which is manifested as a sharp fluctuation in angular velocity and a sharp change in posture. Stillness of movement: A characteristic after a fall is the cessation of movement. Usually the device will detect a period of acceleration and angular velocity close to zero. These characteristics can be captured by accelerometers and gyroscope sensors to help the system detect fall events.

[0056] According to a preferred embodiment, the acceleration amplitude formula is as follows:

[0057]

[0058] Collect three-axis acceleration data a_x, a_y, a_z in real time. If the acceleration amplitude |A| suddenly exceeds a preset threshold (such as 2 times the acceleration of gravity), it can be suspected that it is a fall event. When the acceleration amplitude |A| suddenly exceeds the threshold, it is marked as a possible fall event.

[0059] According to a preferred embodiment, the formulas for the angular velocity amplitude and the attitude change angle are as follows:

[0060]

[0061] Δθ=θ final -θ initial ,

[0062] Collect three-axis angular velocity data ω_x, ω_y, ω_z in real time. If the angular velocity amplitude |ω| changes suddenly, it also indicates that a drastic change in posture may have occurred. Before and after the peak acceleration occurs, check whether the angular velocity amplitude |ω| changes drastically. If the angular velocity changes significantly, the fall is further confirmed. At the same time, when the posture angle changes by more than a certain angle (such as 60° or 90°), the fall is further confirmed. During the calculation process, possible false alarm scenarios include fast daily activities such as jumping, sitting down, standing up, etc. In order to reduce false alarms, context-aware judgments can be made by integrating multiple sensor data and combining the user's historical behavior patterns. Some falls may not trigger obvious changes in acceleration or angular velocity, resulting in missed reports. In order to reduce missed reports, the detection sensitivity can be increased, or the accuracy can be improved through machine learning models.

[0063] Based on the communication module, a customized encryption process is used to exchange data between the device terminal and the user management platform, thereby avoiding problems such as data being intercepted during transmission and causing sensitive data leakage of personnel information.

[0064] Embodiment 3:

[0065] Take the exercise data reporting of the elderly in the present invention as an example.

[0066] The communication module includes two encryption modes. One is AES encryption and the other is RSA mode. The former is used in the two data communication processes where the terminal device requests the user management platform to allocate the RSA key and confirms the receipt of the RSA key. The latter is used throughout the entire business-related process between the terminal device and the user management platform.

[0067] The communication module uses SOCKET communication technology to establish a connection channel. After the channel is successfully established, the terminal device and the user management platform enable the AES encryption mode and send an instruction to allocate the RSA key to the user management platform. The instruction is first encrypted by the AES key X agreed upon by the terminal device and the user management platform. The native instruction is a JSON string containing information related to the terminal device. It is encrypted by the AES key and generated into an encrypted string of the HEX type and sent to the user management platform using SOCKET. After receiving the information, the user management platform uses the key X to decrypt it. After decryption, it confirms the legitimacy of the terminal device based on the relevant information. After passing, it will generate the RSA key S of the user management platform and save it locally. Then, the public key SP of the key S is extracted to construct a JSON string of relevant information. Referring to the same AES encryption mode as the terminal device, it is generated into an encrypted string of the HEX type and sent to the device terminal through SOCKET. After receiving the data, the device terminal uses the key X to decrypt it to obtain the public key SP and save it locally. At the same time, the public key SP is used to encrypt and generate the RSA key C of the device terminal. After that, the public key CP of the secret key C is extracted to construct a JSON string of related information, and then a confirmation instruction is sent to the user management platform. The user management platform saves the public key CP and responds to this instruction to the terminal device, and switches to RSA mode. After the device terminal receives the response instruction from the user management platform, it also switches to RSA mode. At this point, the data encryption level is improved and the data cannot be cracked.

[0068] After the RSA mode is successfully switched, the communication module will extract the motion data of the elderly in the storage unit, encrypt the constructed motion data instructions with the public key SP, and send them to the user management platform after encryption. After receiving the data, the user management platform uses the private key of the corresponding secret key S to decrypt it, and saves the data in the platform after decryption. Then, the response data is encrypted and sent using the public key CP, and the terminal device uses the private key of the secret key C to decrypt it. After decryption, the entire motion data reporting process is completed.
