Further, if it is determined that the mutual authentication is successful, the method can further include: the candidate to-be-connected health monitoring device and the base station generate a shared key by using a preset key agreement algorithm based on the fifth public key, the fifth private key corresponding to the fifth public key, the sixth public key and the sixth private key, and send the shared key to the server, and the server stores the correspondence between the identifier information of the health monitoring device and the shared key. In specific implementation, after the mutual authentication between the base station and the candidate to-be-connected health monitoring device is successful, the base station and the candidate to-be-connected health monitoring device further generate a shared key by using an ECDH key agreement algorithm based on the fifth public key, the fifth private key corresponding to the fifth public key, the sixth public key and the sixth private key.

Further, the base station sends the shared key to the server, and the server stores the correspondence between the identifier information (that is, the MAC address information of the to-be-activated health monitoring device) of the candidate to-be-connected health monitoring device and the shared key after receiving the shared key sent by the base station.

[0058] 546、 After the mutual authentication is successful, the base station and the candidate to-be-connected health monitoring device are connected. In this step, after the mutual authentication between the base station and the candidate to-be-connected health monitoring device is successful, a Bluetooth connection is established.

[0059] 547、 After the health monitoring device and the base station are connected successfully, the health monitoring device returns connection success information to the base station.

[0060] 548、 The health monitoring device reports the collected health monitoring data to the base station. In a specific implementation, the health monitoring device encrypts the real-time collected health monitoring data according to the shared key negotiated with the base station and a preset encryption algorithm to generate encrypted health monitoring data, and sends the encrypted health monitoring data to the base station. The preset encryption algorithm can be, but is not limited to, a symmetric encryption algorithm such as an AES (Advanced Encryption Standard) encryption algorithm, and the embodiments of the present application do not limit this.

[0061] 549、 The base station sends the health monitoring data uploaded by the health monitoring device to the server. In a specific implementation, the base station receives the encrypted health monitoring data uploaded by the health monitoring device, and uploads the encrypted health monitoring data to the server. When the base station receives the encrypted health monitoring data uploaded by the health monitoring device, the base station can also decrypt the encrypted health monitoring data based on the shared key negotiated with the health monitoring device and the preset encryption algorithm, process the decrypted health monitoring data, such as processing the format of the health monitoring data into a data format supported by the server, and then upload the processed health monitoring data to the server after encrypting the processed health monitoring data according to the shared key and the preset encryption algorithm.

[0062] 5410、 The server stores the health monitoring data uploaded by the base station. In a specific implementation, the encrypted health monitoring data uploaded by the base station to the server further includes identification information of the health monitoring device, the server looks up the corresponding shared key according to the identification of the health monitoring device, the server decrypts the encrypted health monitoring data according to the shared key, and stores the decrypted health monitoring data.

[0063] 5411. The server returns a data upload success notification to the base station. Therefore, after health monitoring data is uploaded to the server, medical staff can use a designated mobile terminal to log in to the server to view and download the health monitoring data of the monitored individuals in real time, thus achieving real-time viewing and monitoring of health monitoring data. The data transmission method provided in this application embodiment activates a health monitoring device through a designated mobile terminal or base station. Upon successful activation, the activation success information is sent to a server. The server marks the health monitoring device as activated. The base station detects connectable monitoring devices within its coverage area, designates these as candidate health monitoring devices, and sends their association information to the server. If the server determines that the connection conditions are met based on the association information and the status of the candidate health monitoring devices, it returns a message to the base station instructing the connection to that candidate health monitoring device. The base station then connects to the candidate health monitoring devices and sends the health monitoring data obtained from each connected health monitoring device to the server. In this embodiment, it is not necessary to use the mobile terminal of the monitored object to activate the health monitoring device and upload the monitored health data to the server. Instead, a designated mobile terminal (such as a medical staff's mobile terminal or an independent mobile terminal) or a base station is used to activate the health monitoring device, and the base station detects connectable candidate health monitoring devices within its coverage area. The server determines whether candidate health monitoring devices meet the connection conditions. The base station connects to the candidate health monitoring devices that meet the connection conditions. The base station can upload health monitoring data obtained from the health monitoring devices to the server in real time. This avoids the problem that the monitored object cannot activate the health monitoring device and upload health monitoring data because it does not have a mobile phone or other mobile terminal, or does not know how to operate the health monitoring application on its mobile terminal. Furthermore, the base station provided in this application embodiment can detect connectable health monitoring devices within its coverage area in real time. When the monitored object wearing the health monitoring device moves and the health monitoring device loses communication with the connected base station, it will be detected in time by a base station that can cover the current location of the health monitoring device, thereby connecting to a base station that meets the conditions and continuing to complete the real-time upload of health monitoring data.
