Range can equally prevent children from going astray from the group, if children have gone beyond the region of setting, ipc monitor terminal will have alarm to mention
Show.
It is as follows to implement detailed step for a kind of children's positioning monitoring system disclosed in this invention:
The first step, check system equipment, before positioning monitoring system is installed, the software and hardware part first to system do sufficiently
Inspection, check whether master positioning base station in system hardware, UWB locating base station, wireless aps and intelligent positioning bracelet work normally,
The monitoring software for monitoring terminal whether normal operation, after inspection, starts to build position detecting system；
Second step is respectively mounted master positioning base station, UWB locating base station and wireless in each room and children's activity region
AP, guarantees at least one master positioning base station of each region, a UWB locating base station and multiple wireless aps, master positioning base station,
UWB locating base station and wireless aps are mounted in same level, are mounted on wall indoors, are fixed by A-frame, triangle
For the supporting leg 27 and wall of bracket at 45 degree of angles, supporting leg 26, in this way can be with perpendicular to 10-20 centimetres of metope, base station and metope distance
Make the glitch-free receiving and transmitting signal in base station, if then can choose longer tripod in outdoor without wall and stand in ground, distance
Half meter of ground or more can do corresponding adjustment according to the actual situation, set each UWB locating base station, wireless aps and master positioning
Base station installation site, guarantee cover all areas in kindergarten comprehensively；
Third step imports scene map at the monitoring software interface of monitor terminal, setting and reality at the interface of monitor terminal
The consistent base station coordinates point of border locating base station coordinate, setting fence choose whether display and go through, it is specified that children's activity range
History track, it is all be provided with after, in monitor terminal display interface it is seen that base station coordinates in scene map and enclosing
Column range；
4th step, when children wear positioning bracelet enter in monitoring range, the UWB positioning and communicating module in positioning bracelet to
Multiple UWB locating base stations send data-signal, and multiple UWB locating base stations determine the first of bracelet according to UWB positioning and communicating module
Then first location information is fed back to the UWB positioning and communicating module in positioning bracelet by location information；Wifi in positioning bracelet
Locating module sends data-signal to multiple wireless aps, and multiple wireless aps signals determine the second of bracelet according to wifi locating module
Then second location information is fed back to the wifi locating module in positioning bracelet by location information；
5th step, master positioning base station receive positioning bracelet in the first location information and the second location information, then by with
Too the first location information and the second location information are transmitted to central server by net, and central server is in the first location information
Data in data and the second location information carry out algorithm fusion, parse location information, location information is then passed through ether
Net is transmitted to monitor terminal；
6th step, checks whether the intelligent positioning bracelet worn in the interface of monitor terminal and children has warning note, point
The label node of monitor terminal monitoring interface is hit, can show the physiological health parameter value of this children, if detected children
Every physiological parameter has been more than human normal health indicator, this label node will be in flashing state, corresponding physiologic parameter value
Also color change will occur, while intelligent positioning bracelet will carry out audio alert and light warning by alarm module；If intelligence
Positioning bracelet falls off or damages energy, children press distress call key, children have gone beyond work set by fence
Dynamic range, intelligent positioning bracelet will all carry out audio alert and light warning by alarm module, while have police in monitor terminal
Report sounds, and the corresponding label of this children can remind care provider timely to check tool in red alarm condition in monitoring interface
Body situation.
The present invention makes full use of UWB location technology, wifi location technology, passes for nurse difficulty problem existing at present
Sense network technology, computer software and hardware technology etc. invent a kind of children's positioning monitoring system, according to actual needs, to system
Innovation in all directions is carried out.Invention increases self safe precaution abilities of children, alleviate the nurse pressure of caregiver,
Solve that function existing for current intelligent positioning monitoring system is not complete, positioning is inaccurate, smart machine is inconvenient to carry and reliable
Property the various problems such as poor, it is ensured that the growth of children's healthy and strong health under the environment of comfortable safety.
Although the embodiments of the present invention have been disclosed as above, but it is not limited in listed fortune in specification and embodiments
With.It can be applied to various suitable the field of the invention completely.It for those skilled in the art, can be easily real
Now other modification.Therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is not limited to
Specific details and legend shown and described herein.
