The stay time threshold value of setting.
Step 2：The speed of visitor is obtained by Big Dipper Differential positioning module, the same time is obtained by accelerometer module
Under visitor acceleration.
Step 3：Main control module in tourist security managing device using polynomial least square approximation come to speed and
The sampled point of acceleration realizes smothing filtering.
Step 4：Judge whether visitor's speed of t is less than 0.1 less than the absolute value of 0.1 (being approximately 0) and acceleration
(being approximately 0).It is to be transferred to step 5；No, t=t+1 is transferred to step 4.
Step 5：Tourist security managing device records the time, and the time is the initial time t for calculating stay time0=t.
Step 6：Whether t=t+1, judge visitor's speed of t less than 0.1 (being approximately 0) and the absolute value of acceleration
It is to be transferred to step 7 less than 0.1 (being approximately 0), no, t=t+1 is transferred to step 4.
Step 7：Tourist security managing device calculates stay time Δ t=t-t of the visitor in certain position0。
Step 8：Judge whether stay time exceedes the threshold value for setting, be to be transferred to step 9, it is no, it is transferred to step 6.
Step 9：Tourist security managing device starts audio alert, and the automatic warning message that visitor's residence time is long
Service monitoring center is sent to the positional information of visitor, and notifies that nearest staff checks.
3-step 9 of above-mentioned steps is realized by the main control module in tourist security managing device.
3rd, wander away prompting
With reference to Fig. 5, prompting of wandering away to implement step as follows：
Step 1：Tourist security managing device A (main frame) and N number of tourist security managing device B1……BN(slave) has independence
Numbering ID, when visitor gets tourist security managing device by the bluetooth module in device to tourist security managing device A
(main frame) and N number of tourist security managing device B1……BN(slave) is bound.
Step 2：Configuration file of the storage in the memory module of tourist security managing device is read, in obtaining configuration file
The threshold value of the distance of setting.
Step 3：Tourist security managing device Bi(i=1,2 ..., N) pass through the bluetooth module of its own to visitor every 1s
Security control apparatus A sends the information, tourist security managing device A receive informations such as numbering, latitude and longitude information, time.
Step 4：Main control module in tourist security managing device A manages dress according under same UTC time with tourist security
Put BiThe longitude and latitude of (i=1,2 ..., N), calculates the distance between tourist security managing device.
Step 5：Between the tourist security managing device that main control module in tourist security managing device A obtains step 4
The threshold value of distance that is read with step 2 of distance be compared, when tourist security managing device A and tourist security managing device
BiWhen the distance between (i=1,2 ..., N) exceedes default threshold value, tourist security managing device A starts language by voice module
Sound warning reminding visitor, and show B on the display module of tourist security managing device AiThe position of (i=1,2 ..., N).
It should be noted last that, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted.Although ginseng
The present invention has been described in detail according to embodiment, it will be understood by those within the art that, to technical side of the invention
Case is modified or equivalent, and without departure from the spirit and scope of technical solution of the present invention, it all should cover in the present invention
Right in the middle of.
