CROSS-REFERENCE TO RELATED APPLICATION This application is a 371 of international application of PCT application serial no. PCT/CN2021/105101, filed on Jul. 8, 2021, which claims the priority benefit of PCT application no. PCT/CN2020/133734, filed on Dec. 4, 2020. The entirety of each of the above-mentioned patent applications is hereby incorporated by reference herein and made a part of this specification. TECHNICAL FIELD The invention mainly relates to the field of medical devices, in particular to an analyte detection system. BACKGROUND The pancreas in a normal human body can automatically monitor the blood glucose level and automatically secrete required amount of insulin/glucagon. In the body of a type 1 diabetes patient, the pancreas does not function properly and cannot produce enough insulin for the body. Therefore, type 1 diabetes is a metabolic disease caused by abnormal pancreatic function, and diabetes is a lifelong disease. At present, there is no cure for diabetes with medical technology. The onset and development of diabetes and its complications can only be controlled by stabilizing blood glucose. Diabetics need to have their blood glucose measured before they inject insulin into the body. At present, most of the testing methods can continuously measure blood glucose level and send the data to a remote device in real time for the user to view. This method is called Continuous Glucose Monitoring (CGM). The method requires the device to be attached to the skin and the sensor in the device is inserted into the subcutaneous tissue fluid. At present, when using the analyte detection system, users need to locate different input positions in the remote device and manually input instructions on the remote device, so as to control the analyte detection system to perform the corresponding functions. This input process is cumbersome and the user experience is poor.
