The transmitting portion of control unit is used using the switched capacitor D/A converters that distorted signals is small, frequency stability is high, receiving portion
Reception, separation and decoding in completion dtmf signal, and exported in the way of 4 parallel-by-bit binary codes；Adjustable dual-audio mould
The dutycycle of formula, can suppress dialing tone and adjustment signal gain automatically, and the data/address bus with standard is compatible with Transistor-Transistor Logic level；Adopt
Control is programmed with VG2 microcontrollers, can be achieved to dial number number progress telephone annunciation and report by DTMF transmission circuits
Police, and the user instruction of reception distal end are operated accordingly to household equipment.
7. the intelligent domestic appliance controller as claimed in claim 6 based on multimedia processor, it is characterised in that the storage mould
Block has 16 bit data bus and 24 bit address buses, the function with Manchester's code, collision detection and repeating transmission；Can be with
Peripheral circuit completes sending and receiving for data together, and full duplex, transmitting-receiving speed can reach 10Mbps simultaneously；Built-in 16KB's
SRAM is used for the buffering of data transmit-receive, supports wire jumper and wire jumper free, the upper operation mode of plug and play；RTL8019AS is operated in jump
Under line mode, IOS3~IOSO is low level, and it is Ox300 to set its I/O base address；The memory module only be to address
0x300~0x31F signal produces response；IRQS2~IRQS0 is low level, and INT0 is selected the output as interrupt requests,
PLl, PLO are that low level sets the function with automatic detection interface type.
8. the intelligent domestic appliance controller as claimed in claim 7 based on multimedia processor, it is characterised in that the analog audio
Video superposition input interface can also carry out color balance processing, the method for the color balance processing to the video image received
Comprise the following steps：
Step 1：The pixel of the image information received is stored in matrix by order module；
Step 2：Order module is ranked up according to the size of each pixel value to the pixel in matrix；
Step 3：Order module set optimization rate as；It is determined that optimization quantity is；Sorted during the point for then needing optimization
Before matrix afterwardsWith it is rearPixel；Therefore the maximum of the pixel of optimization can be drawn
ProducePoint, and optimize pixel minimum valueProducePoint；
Step 4：Color value is more than by pixel optimization modulePixel be all modified to；Color value is less thanPixel be all modified to；
Step 5：Generation color value scope existsNew images；
Step 6：Set new color value as, then have：;；
It may finally draw：。
