Module to the energy-storage module of device rear end, Voltage stabilizing module, send the on and off that control module, drive module, car light are powered；Switch
The KI ends of module under the control at KC ends, are realized conducting and are disconnected with KO ends, and with turning on and disconnecting the switching of two states, produce
Raw switching signal；The state of KC ends acquiescence, is the conducting for controlling KI ends and KO ends；
Energy-storage module is used to be turned at KI ends and KO ends, when having power module to power, collects and store electric energy；At KI ends and KO ends
Disconnect, when power module is not powered, discharge the electric energy of storage, as temporary source, to send control module temporary power；
Voltage stabilizing module is used for when power module or energy-storage module are powered, to send the power supply output that control module provides stabilization；
Voltage stabilizing module obtains electric energy by WI ends from outside；
Sending control module is used to, by Voltage stabilizing module, be powered by power module or energy-storage module；KI ends and KO are detected by FU ends
The instantaneous state for disconnecting is held, and is activated from resting state according to the state；The conducting at KI ends and KO ends is detected by FI ends and is broken
Being switched fast for two states opened and the switching signal for producing, and according to the switching signal, send to drive module by FO ends
Corresponding drive signal, drives car light to send visible light signal by drive signal；The state of FO ends acquiescence, output one makes drive
Dynamic model block can control the level that car light is persistently lighted；
Drive module is used to, according to the drive signal that control module FO ends export is sent, drive car light to send visible light signal；Drive
The state of dynamic model block acquiescence, is that control car light is persistently lighted；
Key command, device provides more than one key command, with the different conditions of different button and its button, represents different
Key command；
The acquisition modes of key command have two kinds of single-button and many buttons, i.e.,：For many buttons, when pressing different buttons, table
Show different instruction implications；For single button, different instruction implications can also be represented with different by under type, including：
Click, it is multi-hit, long by；Click, it is once short tactile to push button；It is multi-hit, it is repeatedly short tactile to push button；Length is pressed, and is pushed button
And continue for some time；
The different switch order of different key command correspondences, the different visible light signal of different switch order correspondences；
Switch order has：More than one switch order is provided；Switch order is the combination of one group of binary number " 1 " and " 0 ", each
" 1 " and " 0 " combination of individual switch order is different；
The KC ends of switch module, according to " 1 " and " 0 " of switch order, the conducting and disconnection at control KI ends and KO ends, when KC terminations
When the signal for receiving is " 1 ", the conducting at control KI ends and KO ends；When the instruction that KC terminations are received is " 0 ", KI ends and KO are controlled
The disconnection at end；Vice versa；
Device provides light illumination mode and communication pattern, and the switching of pattern is realized by switch control module；Refer to button is not received
When making, device is light illumination mode, and switch control module keeps KI ends, the conducting at KO ends, to realize power supply mould by controlling KC ends
Continued power of the block to back-end circuit；After switch control module receives key command, device enters communication pattern, switch control
Module realizes that KI ends are turning on and disconnecting being switched fast for two states with KO ends by controlling KC ends, and switch is sent to reach
The purpose of signal；
Car light is used under light illumination mode, there is provided the illumination of stabilization；In a communication mode, under the driving of drive module, send
Visible light signal；
Each module of device works on power, and switch control module, transmission control module initialization, energy-storage module storage electric energy send
Control module is directly powered by Voltage stabilizing module by power module, and switch module acquiescence controls KI ends and KO ends to keep leading by KC ends
Logical, drive module acquiescence control car light persistently lights illumination；
Switch control module starts to detect key command, enters if key command is detected and lead to after device works on power
Letter pattern, when by being still not detected by key command after a time delay, switch control module enters resting state, and switch module is write from memory
Recognize and control KI ends and KO ends to be held on by KC ends；
Control module is sent after device works on power, starts detection switch instruction, enter logical if switch order is detected
Letter pattern, when by being still not detected by switch order after a time delay, sends control module and enters resting state, and drive module is write from memory
Recognize control car light persistently to light；
Device, by pushing button, key command is sent to switch control module in communication pattern；By switch control module root
According to the key command for detecting, switch order is sent to the KC ends of switch module, control KI ends and KO ends are in conducting and disconnection two
The switching of the state of kind, is switched by state, produces switching signal；Energy-storage module discharges the electricity of storage when KI ends and KO ends disconnect
Can, it is transmission control module temporary power by Voltage stabilizing module；Control module is sent, detects what KI ends and KO ends disconnected by FU ends
Instantaneous state, and activated from resting state according to the state；Detect that KI ends and KO ends are turning on and disconnecting two states by FI ends
Switch the switching signal for producing, and according to switching signal, by drive module according to drive signal, control car light sends visible ray letter
Number.
