Design of hardware and software, it is achieved the transmission of character string；Receiving terminal, uses CCD to use high frame frequency as photo-detector, hardware device
More than 100fps, high sensitivity, high-responsivity CCD camera；Camera shoots with frame frequency identical with light source, and designs
Software carries out collection and the process of data to CCD camera, the rule of modulated signal is presented, obtains corresponding gray value,
Thus complete the transmittance process of information, it is achieved the reception of character string；Described charging socket is arranged at the side of door close；
Described field programmable gate array, inside includes configurable logic blocks CLB, input/output module IOB and interior
Three parts of portion's line；FPGA utilizes small-sized look-up table (16 × 1RAM) to realize combination logic, and each look-up table is connected to one
The input of individual d type flip flop, trigger drives other logic circuits again or drives I/O, thus constituting and both can realize combination
Logic function can realize again the basic logic unit module of sequential logic function, and these intermodules utilize metal connecting line to interconnect
Or it is connected to I/O module；The logic of FPGA loads programming data by internally static storage cell and realizes, and is stored in
Value in memory cell determines the side of connection between logic function and each module of logical block or between module with I/O
Formula, and finally determine the function achieved by FPGA, FPGA allows unlimited number of programming.
4. according to the water heater control system of a kind of long-range LBS location navigation described in claim 1, it is characterised in that described use
Family equipment can use photographic head to shoot LED lamp, and have application program and be decoded LED, obtains the volume of correspondence
Code information, is attached with navigation server by wireless network, obtains navigation information；Key to be sent is TTL level letter
Number, i.e.+5V represents high level " 1 ", and 0V represents low level " 0 "；Described LED drive module includes PNP type paster audion
S8550 and related peripheral device thereof, for realizing the signal of telecommunication conversion to optical signal；One one-to-many of described optical key module
Device；Optical key is a kind of transmitting terminal based on single-chip microcomputer STC12C2052AD design.
5. according to the water heater control system of a kind of long-range LBS location navigation described in claim 1, it is characterised in that navigation clothes
Business device storage LED coding and the corresponding informance of position, cartographic information, described navigation server is for the calculating of indoor positioning；
After subscriber equipment inputs target resource, use handheld device photographic head shooting LED lamp；Then, the application in handheld device
LED is decoded by program, obtains the coding information of correspondence；Handheld device is carried out even by wireless network and navigation server
Connect, the relation table in enquiry navigation server, obtain LED position；Application program on server uses indoor positioning algorithms
Obtain the positional information of handheld device, and return to handheld device, in conjunction with the map in handheld device, it would be desirable to navigation information
It is shown in user device screen.
