Embodiment 8：
The real-time release of dimmer command：
It is exactly to send dimmer command principal mode that control stick is slided on network Control Console.The control stick slided on network Control Console
It is very more, the position of all slip control sticks is gathered, could form dimmer command data after calculating processing is dealt into the machine
PC104 so using multiple 51 singlechip groups into Single Chip Processor Groups, is each responsible for data acquisition, the calculating processing sum number of Control Console
According to I/O, to avoid data exchange in multiple shared RAM of 51 single-chip data deposit.51 microcontrollers and PC104 are held using parallel port is soft
Hand transmits data.It is transmitted in this way, data calculate side in acquisition, operating lever operation action generation is slided to transmission so as to reduce
Dimmer command to the machine PC104 time.51 microcontrollers notify it to start to receive data to PC104 using parallel port interrupt, once
Transmit a dimmer command data block.After network Control Console PC104 receives dimmer command data block, by network to all-network
Light-adjusting cabinet broadcasts 802I3 frames, and the data of frame are dimmer command data blocks.After binding and layout, frame is transmitted to by network interface card using long-range DMA
Transmission buffering area, initialization send control register, then send frames on network.The network interface card of network light-adjusting cabinet passes through this
Frame deposit is received buffering ring by ground DMA, is coordinated by host and long-range DMA the frame received in buffering ring reading in memory.Then,
Parallel port interrupt request is proposed to 51 microcontroller of the machine, receives dimmer command by simultaneously port transmission dimmer command data, 51 microcontrollers
Afterwards, DMX512 control data control lamp luminescences are exported.The transmission of dimmer command is as shown in Figure 2.
Meanwhile 51 microcontroller of network light-adjusting cabinet gathers current dimming state data, forms state data packets to PC104 parallel ports
Request is interrupted, and is transferred to PC104 by parallel port, each network light-adjusting cabinet status data includes loop current 96, drawer temperature
48, drawer use state 48, light-adjusting cabinet voltage 6 and fan-status 24.PC104 is on the one hand by light-adjusting cabinet state at this
It is shown on machine LCD, while by network, by these status data transfers to network monitoring host, network monitoring host application journey
Sequence shows in visual form light-adjusting cabinet state in the Shipping Options Page of corresponding network light-adjusting cabinet.If the data in status data
It transfinites, then schemes sudden strain of a muscle and sounding alarm.
Embodiment 9：
51 microcontrollers and PC104 soft handshake communication parallel：
It once needs to transmit a data block between 51 microcontrollers and PC104, and is two-way, so using parallel interface,
Work in two-way EPP modes.But if using standard parallel EPP modes of shaking hands firmly, 51 microcontrollers must have to be connect accordingly
Mouth cooperation (such as 8255) could be realized.In the system, 51 microcontrollers have some parallel ports that can utilize in itself, so ourselves
Soft handshake method is defined, and is made
The standard of soft handshake is not clashed with EPP modes, otherwise can not just be realized.
The signal wire of soft use of shaking hands is as follows：
51 microcontrollers and PC104 transmitted in both directions：Data cable Data0-Data7；51 microcontrollers are to PC104：Interrupt requests ACK is accurate
Get ready/data have taken nWait away；PC104 is to 51 microcontrollers：Interrupt requests nlnit, be ready to/data have taken nWrite away.51
When microcontroller is needed to PC104 transmission data, parallel port interrupt request (ACK) is proposed to PC104.After PC104 enters parallel port interrupt,
Inform that 51 microcontrollers receive DSR by putting nWrite signals, 51 microcontrollers are after the nWfite home position signals of PC104
Data are sent, and nWait home position signals, PC104 is made to receive a data after detecting nWait home position signals, and are made
NWrite is set to 0.51 microcontrollers are ready for sending next data after sentencing the clear position of nWfite signals.It will be opened after often sending a data
Dynamic timing, is timed to and does not still detect signal, then it is assumed that transmission goes wrong, and stops the transmission of this data block.51 is single
It is as shown in Figure 3 that piece machine sends data block program circuit.
