Background
In the prior art, a blood glucose detection system uses a blood glucose meter that is connected to a Personal Computer (PC) terminal by a Universal Serial Bus (USB), and logs in to a server imss (diabetes information management software) client, and uploads blood glucose data to an imss server for viewing, uploading, downloading, and managing the blood glucose data.
However, because different operating systems of the PC terminals are different, before the blood glucose meter and the PC terminal are connected, a corresponding USB driver needs to be installed for the operating system of the PC terminal, which is inconvenient to operate. Even if the USB driver is installed, the PC cannot identify the blood glucose meter due to the fact that the reduced operating system lacks many USB system configuration files, and therefore blood glucose data cannot be uploaded to the iwsm server. In addition, due to the adoption of the USB wired connection, the fault risk is increased.
Therefore, a new method is needed, which can simply and rapidly upload blood glucose data.
