Specific embodiment
Please refer to figs. 1 to 4, that show the specific structure of the preferred embodiment of the utility model, include
Host 10 and multiple sub-controllers 20.
The host 10 has bus management module 11, keystroke interface 12, the wireless communication for connecting with portable equipment 31
Module 13, the usb 14 for being connect with the equipment 32 with usb communication function and for connecting with upper layer bus 33
LIN transceiver 15；The bus management module 11 is responsible for the signal of each interface input of processing, translates into corresponding bus internal command
Format is simultaneously sent in bus；The portable equipment 31 is smart phone, tablet computer etc., the equipment 32 with usb communication function
For PC etc.；Keystroke interface 12 is directly connected to the key of the port MCU of host 10, and switch atmosphere can be configured in 10 program of host
Enclose the system-level control of the functions such as lamp system；The host 10 and common portable equipment that the wireless communication module 13 is used for as system
