Member and centralized control unit, the transmitting unit include information decoding unit, miniature laser driver and microlaser sequence,
The receiving unit includes optical receiver sequence units and signal driving sequence units, and the controlled unit includes load switch
The action message of the master switch sequence is encoded to control information by sequence and execution unit sequence, the information coding unit
After be sent to the centralized control unit, the information decoding unit be driven after controlling information decoding by the miniature laser
Device controls the microlaser sequence and carries out corresponding actions, and the optical receiver sequence units are received described miniature by optical fiber
The action message of laser series simultaneously drives sequence units to control load switch sequence progress corresponding actions by signal, described negative
Load switch sequence accordingly controls the execution unit sequence movement.
Switch in the master switch sequence connects power supply by pull-up resistor respectively and is separately connected the information and compiles
Code unit, the centralized control unit control connects multiple information coding units, to receive the control information of multichannel.Just
The information coding unit connects power supply by pull-up resistor under normal state, and the information input terminal of information coding unit is logic 1
State, after some in master switch sequence closes the switch, information coding unit corresponds to the information input terminal of the switch by should
Switch ground connection, the information input terminal are logical zero state.Information coding unit is carried out according to the switch motion information that sequence is opened in master control
