The obtain manner of key command has single-button and many buttons two kinds, that is:, for many buttons, when pressing different buttons, represent different instruction implications; For single button, with different by under type, different instruction implications can also be represented, comprising: click, multi-hit, long by; Click, once short tactile pushing button; Multi-hit, repeatedly short tactile pushing button; Length is pressed, and pushes button and continues for some time;
The switch command that different key commands is corresponding different, the visible light signal that different switch commands is corresponding different;
Switch command has: provide a more than switch command; Switch command is the combination of one group of binary number " 1 " and " 0 ", and " 1 " and " 0 " compound mode of each switch command is different;
The KC end of switch module, according to " 1 " and " 0 " of switch command, the conducting that control KI holds and KO holds and disconnection, when the signal that KC termination receives is for " 1 ", the conducting of control KI end and KO end; When the instruction that KC termination receives is for " 0 ", the disconnection that control KI holds and KO holds; Vice versa;
Device provides light illumination mode and communication pattern, and the switching of pattern is realized by switch control module; When not receiving key command, device is light illumination mode, and switch control module is held by control KC, keeps the conducting of KI end, KO end, to realize the continued power of electric power source pair of module back-end circuit; After switch control module receives key command, device enters communication pattern, and switch control module is held by control KC, realizes KI end and holds in conducting and the quick switching disconnecting two states, to reach the object of transmit button signal with KO;
Car light is used under light illumination mode, provides stable illumination; In a communication mode, under the driving of driver module, send visible light signal;
The each module of device works on power, switch control module, the initialization of transmission control module, energy-storage module storage of electrical energy, send control module directly to be powered by power module by Voltage stabilizing module, switch module acquiescence holds control KI to hold by KC and KO holds maintenance conducting, and driver module acquiescence controls car light and continues to light illumination;
Switch control module is after device works on power, start to detect key command, if key command detected, enter communication pattern, when key command being detected not yet after a time delay, switch control module enters resting state, and switch module acquiescence holds control KI to hold by KC and KO holds maintenance conducting;
Send control module after device works on power, starting sense switch instruction, if the switch command of detecting, entering communication pattern, when switch command being detected not yet after a time delay, send control module and enter resting state, driver module acquiescence controls car light and continues to light;
Device, when communication pattern, by pushing button, sends key command to switch control module; By switch control module according to the key command detected, the KC to switch module holds transmit button instruction, and control KI holds and KO end switches in conducting and disconnection two states, is switched, produce switching signal by state; Energy-storage module is when KI end and KO end disconnect, and the electric energy that release stores, by Voltage stabilizing module for sending control module temporary power; Send control module, held by FU and detect the instantaneous state that KI holds and KO end disconnects, and activate from resting state according to this state; Hold detection KI end and KO to hold in conducting and the switching signal disconnecting two states switching generation by FI, and according to switching signal, by driver module according to drive singal, control car light and send visible light signal.
