step 1, defining a Bluetooth Beacon Beacon as an anchor node, and acquiring coordinate values of each anchor node;
step 2, acquiring a real-time strength value of a Bluetooth signal sent by a first positioning node received by each anchor node, and obtaining a distance value between the first positioning node and each anchor node through an RSSI ranging algorithm according to the Bluetooth signal strength value;
acquiring a Bluetooth signal strength value sent by a second positioning node received by each anchor node, and obtaining a distance value between the second positioning node and each anchor node through an RSSI (received signal strength indicator) ranging algorithm according to the Bluetooth signal strength value;
step 3, establishing an equation set, wherein the equation set comprises the following steps:
Az＝b，
wherein,
wherein x1、x2…、xkExpressed as abscissa value, y, of each anchor node1、y2…、ykExpressed as ordinate values of the respective anchor nodes, d1、d2…dkExpressed as a distance value between the positioning node and each anchor node;
substituting the coordinate values of the anchor nodes obtained in the step 1 into an equation set, substituting the distance values between the first positioning node and the anchor nodes obtained in the step 2 into the equation set, calculating and solving through the equation set to obtain the coordinate values of the first positioning node, and recording as (k)1,m1)；
Substituting the coordinate values of the anchor nodes obtained in the step 1 for an equation set, substituting the distance values between the second positioning nodes and the anchor nodes obtained in the step 2 into the equation set, calculating and solving through the equation set to obtain the coordinate values of the second positioning nodes, and recording as (k)2,m2)。
9. The medical intelligent monitoring method based on the medical intelligent bracelet according to claim 5, wherein the bracelet further comprises a display module, the display module is used for displaying a two-dimensional code, and the two-dimensional code is used for scanning and acquiring through a terminal device: item information of the patient needing self-care, patient re-diagnosis time information and patient re-diagnosis place information.
10. The medical intelligent monitoring method based on the medical intelligent bracelet according to claim 9, wherein the terminal device is any one of a mobile phone or a tablet computer.
