2) instruction is inputted to computer, the USB interface of the USB interface of this instruction by computer, USB transceiver reaches the USB converting unit of USB transceiver and changes, USB converting unit is connected with central processing unit, for the instruction that becomes the central processing unit of USB transceiver to identify the USB instruction transformation of computer, central processing unit is connected with RF Transmit-Receive Unit, above-mentioned instruction, after central processing unit is processed, is sent to the wireless transceiver being connected with digital camera and external flash lamp by RF Transmit-Receive Unit; Same, RF Transmit-Receive Unit receives the information that wireless transceiver feedback is come, after processing, central processing unit converts the discernible usb data of computer to through USB converting unit, then return to computer, the RF Transmit-Receive Unit of USB transceiver is under normal conditions in accepting state, in the time that central processing unit sends order, this RF Transmit-Receive Unit, in transmission state, returns to accepting state immediately after being sent completely;
3) instruction of computer is after USB transceiver sends, RF Transmit-Receive Unit in the wireless transceiver being connected with digital camera and photoflash lamp receives, instruction after reception is through central processing unit processing, and convert through USB converting unit the USB instruction that digital camera can be identified to, then process by the USB interface of wireless transceiver, the central processing unit that this instruction is sent to digital camera by the USB interface of digital camera, digital camera carries out the adjustment of working status parameter according to the USB instruction receiving; After digital camera is adjusted working status parameter, this parameter is sent back to the USB converting unit of wireless transceiver through the USB interface of digital camera, the USB interface of wireless transceiver, be converted to the parameter that wireless transceiver can be identified, then central processing unit is sent to this parameter the USB transceiver being connected with computer through RF Transmit-Receive Unit, under the common state of this RF transceiver, it is also accepting state, after the order of reception central processing unit sends parameter, return to immediately again accepting state; The working status parameter of digital camera is after USB transceiver receives, through central processing unit processing, and be converted to through USB converting unit the USB parameter that computer can be identified, send again computer to, on computer screen, show the working status parameter of the digital camera after this adjustment, thereby realize the adjustment of computer logarithmic code camera working status parameter;
4) on the other hand, in the time need to adjusting the working status parameter of photoflash lamp, instruction is inputted to computer, this instruction is sent to through the RF of USB transceiver Transmit-Receive Unit the wireless transceiver being connected with external flash lamp, after the RF Transmit-Receive Unit of wireless transceiver receives, through central processing unit processing, be converted to through converting unit the instruction that photoflash lamp can be identified again, then through hot shoe seat, hot shoe interface, reach the central processing unit of photoflash lamp, central processing unit is adjusted working status parameter according to this instruction, then after adjusting, data are through hot shoe interface, hot shoe seat reaches the converting unit of wireless transceiver, the data that can identify through being converted to wireless transceiver, again after central processing unit is processed, be wirelessly transmitted to the RF Transmit-Receive Unit of USB transceiver by the RF Transmit-Receive Unit of wireless transceiver, again after central processing unit is processed, be converted to by USB converting unit the data that computer can be identified, then through USB interface, the USB interface of computer reaches the central processing unit of computer, on computer screen, show the working status parameter of the photoflash lamp after this adjustment, thereby realize the adjustment of computer to photoflash lamp working status parameter,
5) when carrying out shooting work and photoflash lamp, synchronously draws while dodging by needs camera, computer is wirelessly transmitted to order the RF Transmit-Receive Unit of the wireless transceiver being connected with digital camera and external flash lamp simultaneously by USB transceiver, the USB interface of then passing through successively central processing unit, USB converting unit, USB interface and the digital camera of wireless transceiver is sent to the central processing unit of digital camera, after treatment, digital camera enters shooting state; The instruction that while digital camera draws triggering sudden strain of a muscle returns to wireless transceiver through the hot shoe seat of digital camera and the hot shoe of wireless transceiver, then this instruction is passed central processing unit processing back through drawing sudden strain of a muscle triggering input unit again, the instruction of after processing, triggering being drawn to sudden strain of a muscle divides two paths to send, wherein a road is triggered the instruction of drawing sudden strain of a muscle and is reached external flash lamp, trigger flashing through converting unit, hot shoe seat; Another road instruction is wirelessly transmitted to the wireless transceiver connecting from different external flash lamps by RF Transmit-Receive Unit, the RF Transmit-Receive Unit of other wireless transceiver is received to trigger and is drawn after the instruction of sudden strain of a muscle, after central processing unit is separately processed, reach connected external flash lamp, trigger flashing by converting unit, hot shoe seat; The cooperation in the triggered time by logarithmic code camera shutter opening time, path one in whole process, the triggered time in path two, when realizing camera shutter and opening, the external flash lamp on the wireless transceiver connecting with camera and synchronize and draw the object of sudden strain of a muscle with external flash lamp and camera shutter on other wireless transceivers of wireless transceiver wireless connections.
