After decode it, and the identity information of return information device holder, while cloud server sends geographical position to intelligent terminal
Solicited message is put, after intelligent terminal receives the Geoposition Request information from cloud server, is sent to cloud server
Present apparatus geographical location information.
The purpose of the present invention can also further be realized by following technical measures：
Aforementioned intelligent alignment system, wherein intelligent terminal are to support the mobile phone of NFC function.
Aforementioned intelligent positioning system information coding method, wherein transfer storage coding method includes：Information is encoded
When, by the data of n byte, the buffering area of a 8n bit is successively put into, that be introduced into is high-order, data deficiencies n byte,
Remaining bit is supplied with 0 in buffer, takes out 6 bit every time, is selected according to its value
Character code in ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123 456789 is made
For the output after coding, constantly carry out, completed until fully entering data conversion；
The first step：First character obtains first character, is got according to this numerical value corresponding on table by moving to right 2
Character, is exactly first aim character；
Second step：First character and 0x03 operated with (＆) and move to left 4, then second character moves to right 4
With the former mutually or (|), obtain second target character；
3rd step：Walk to gather more than and finally obtain (n+1)th target character；
When former data are not the integral multiples of n, if finally remaining next input data, 1 is added after coding result
"="；If being finally left two input datas, add 2 "=" after coding result；If being finally left n data, coding knot
Just add n-1 "=" after fruit, if not being left any data, without addition.
Aforementioned intelligent positioning system information coding method, wherein cloud server decode it after coding information is received
Method for carry out inverse operation obtain true form.
Compared with prior art, the beneficial effects of the invention are as follows：Intelligent positioning system intelligent terminal embeds massaging device
NFC label carry out induction mode and read data, massaging device is avoided because charging or replacing battery without separately powering up power supply
That brings is inconvenient for use；Intelligent terminal need not install any App, as long as supporting NFC function, by sensing NFC chip, will obtain
To relevant information, suitable for the fast track to motive objects etc., positioning.The information coding method of the alignment system of the present invention is complete
Compatible NFC chip provides a kind of data-encoding scheme, can meet grid information while chip memory space is saved
The requirement of transmission, solve NFC chip memory is smaller, traditional approach positioning slowly and part NFC chip compatibility issue.
