s109: calculating the position relation between the preset position and the position information;
s110: and extracting the vibration module corresponding to the position relation, starting the vibration module corresponding to the position relation, and indicating the walking direction to the user by the started vibration module.
Specifically, in S101, four vibration modules are disposed at the quartering position of the navigation bracelet, and the four vibration modules are respectively used for indicating the front, rear, left, and right positions of the user, and the four vibration modules do not fixedly indicate a certain direction. The user wears the navigation bracelet earlier to under the normal flagging state of arm, observe the position that every vibration module distributes, then reset the direction that every vibration module instructed, for example, be located the navigation bracelet the place ahead for vibration module A1, set the direction that vibration module A1 instructed as the place ahead so, explain with user's visual angle, the 12 o' clock directions of navigation bracelet are promptly in the place ahead of navigation bracelet.
The normal state of arm drop is similar to the state of arm when walking, and the swing amplitude of arm is smaller when walking, so the direction indicated by the vibration module when arm drop can also represent the direction indicated by the vibration module when walking.
In S102, an air pollution index uploaded by each air detection device is acquired.
In S103, the air detection device is set at a preset position, a corresponding relationship is established between the air pollution index uploaded by the air detection device and the preset position set by the air detection device, and the air pollution index of the place can be grasped according to the preset position.
And when the air pollution index is updated, synchronously updating the corresponding relation comprising the air pollution index.
In S104, when the user wears the navigation bracelet and goes out, the system acquires the position information uploaded by the navigation bracelet, wherein the position information comes from a positioning module in the navigation bracelet.
In S105, a topographic map of the hospital is built in the system, the topographic map covers each path in the hospital, the path where the user is located is determined according to the position information, the path is defined as a first path, when the user enters a next path, the next path is defined as the first path, and the definition of the previous path is cancelled.
A second path, which may include multiple paths, is extracted that is connected to the first path.
In S106, it is determined whether the number of second paths is greater than one.
In S107, if the second path includes two or more paths, it is necessary to provide a navigation service for the user, and a preset position closest to the current position information of the user is extracted from each second path.
For example, the preset position a on the second path a, the preset position B on the second path B, and the preset position C on the second path C are extracted.
And then extracting an air pollution index A corresponding to the preset position A, extracting an air pollution index B corresponding to the preset position B, and extracting an air pollution index C corresponding to the preset position C.
In S108, an air pollution index having the smallest value is extracted from the three air pollution indexes.
And if the numerical value of the air pollution index A is minimum, extracting a preset position A.
In S109, the positional relationship between the preset position a and the user' S current position information is calculated.
In S110, if the preset position a is located on the left side of the current position information of the user, extracting a vibration module located on the left side of the navigation bracelet, and starting the vibration module on the left side to remind the user to walk to the left side.
If the second paths are densely distributed and cannot be distinguished only by the left side or the right side, at the moment, the user adjusts the occupation of the user, so that the vibration module in front of the navigation bracelet is right opposite to each second path, and when the vibration module in front is started, the user walks to the right front to find the correct second path.
Example two
As shown in fig. 2, the user sets a travel distance;
calculating a first distance traveled by the user, and subtracting the first distance from the appearance distance to obtain a second distance;
extracting a shortest total path connecting the first path to an initial position;

if yes, extracting a vibration module behind the indication, starting the vibration module, and reminding a user to return according to the original path.
Recording the path walked by the user from the starting position, and defining the path as the original path.
As shown in fig. 3, when the user returns along the original route, whether the user deviates from the original route is determined according to the current position information of the user;
if yes, calculating the position relation between the original path and the current position information of the user;
and extracting the vibration module corresponding to the position relation, starting the vibration module corresponding to the position relation, and indicating the walking direction to the user by the started vibration module.
Specifically, the user can set a parameter of the travel distance before walking each time, when the user goes out, the system calculates a first distance that the user has walked according to the change of the position information, and then the travel distance subtracts the first distance to obtain a second distance, wherein the second distance is the distance to be walked by the user.
Extracting a second path connected with the first path, extracting a third path connected with the second path, always extracting an Nth path connected with an initial position, forming a plurality of total paths from the first path to the Nth path, extracting a shortest total path from all total paths formed by the system, judging whether the shortest total path is less than or equal to the second distance, if so, indicating that the shortest total path exceeds a set travel distance if the user continues to walk forwards, and at the moment, starting a vibration module behind a navigation bracelet to remind the user to return according to the original path.
And in the walking process of the user, recording the walking path of the user according to the change of the position information, and defining the walking path as an original path.
And when the user returns from the original path, the user walks according to the original path, when the position information of the user is not on the original path, the navigation service is provided for the user again, the position relation between the original path and the current position information of the user is calculated, a vibration module corresponding to the position relation is extracted, and the vibration module is started.
EXAMPLE III
And uploading the complete walking path after the user finishes walking, wherein the walking path can be downloaded and used by other users.
