Take a kind of intelligent terminal of supporting video as example, the communication pattern that intelligent terminal adopts comprises: speed is the asynchronous communication of 9600bit/s, and each byte data adopts 11 and transmits: 1 initial, 1 stop, a bit check and 8 bit data.Information is with the form transmitting-receiving of frame, and on a complete information frame, continuous byte sequence forms, and clear and definite beginning and end mark are arranged, so that the take over party can identify a complete frame, the frame format of agreement regulation is as shown in table 1.
Table 1 frame format
Intelligent terminal can transmit simple video message, selects bus type RS-485 as communication interface; Each intelligent terminal utilizes built-in single-chip microcomputer reception from the information corresponding to self of main frame as slave computer; Main frame can adopt broadcast mode to send message, also can realize point-to-point communication; Intelligent terminal has self a address, realizes between the two communication by handshake.
The hardware that intelligent terminal adopts comprises:
Support that the acp chip of the intelligent terminal of video is the video superimpose chip, the function of realization comprises:
(1) correctly communicate by letter with main frame according to the agreement of appointment, the send and receive multipage tranaction; (2) character that main frame sends is constantly taken out in the addressing by the video superimpose chip from self-built character library, the character of appointment is superimposed on video; (3) support by keyboard, the note that receives to be carried out the operation of appointment, be divided into three buttons according to actual conditions and carry out different operating: button 1 is completed upwards page turning demonstration character, button 2 realizes that downward page turning shows character, the short message that button 3 deletions have been read; (4) can tackle burst power cut-off incident and response processing, canned data before still can reading after again resetting.
The video superimpose chip can be selected eight kinds of different video display modes by three line sel2~sel0, referring to table 2, can show at most 8 (OK) * 16 (row)=128 a different 16*16 dot character.
The model selection that table 2 video superimpose chip is supported
The video superimpose chip is comprised of several functional units such as inner sequential control, address code generation, overlaying character information processing, video synchronizing information processing, self-sustained oscillation loop and display mode selections, the character information that is used for storing in the outer EEPROM of sheet, single dual port RAM or Flash changes the information that may be superimposed on vision signal into, and can regulate the superposed positions of character on monitor by inner sequential control.The character superpositing unit module that forms with the video superimpose chip is that the mode that articulates with uniqueness is operated in the frequency image monitoring system that is comprised of video camera and monitor.
Stack enters a 16*16 dot character information in the video superimpose chip, takies storer 32byte.The explanation lattice information form and at the storage mode of storer as an example of character H example supposes that the address realm of character H in storer is 0030H~004FH, altogether 32 bytes.Table 3 has recorded the lattice information form of character H, and the video superimpose chip is read the character lattice information and it is converted into the information that can be superimposed upon on original video image by the address wire reference-to storage.
Table 3 character H lattice information form
The character library circuit:
Support in the intelligent terminal of video, because overlaying character must change arbitrarily, thus except the secondary character library of standard, self-defined 100 character icons also, total is about 8000 characters; Each character takies 32byte, and the information of total data takies approximately 300kbyte; The expense of lattice information that directly transmits these characters is very large, so add that a slice 512K ROM preserves the lattice information of these characters and as self-built character library.Single-chip microcomputer only needs to send to from the corresponding address of character self-built character library that host computer receives paging preservation in two 2KRAM, and at this moment the data in RAM are called the offset address of character.During reading, the RAM at first offset address of output character in the EEPROM that deposits self-built character library, is then exported the lattice information of corresponding character again by the ROM of this locality.The video superimpose chip needs only with being connected the offset address that can seek character with the outer RAM of seven address wire braces of A5~A11 of video superimpose chip with the outer RAM of sheet being connected of character repertoire, transmitted dexterously font address, compress the data volume of serial communication, reduced the capacity of RAM.

Need single-chip microcomputer to send the offset address of character in character library to RAM in the intelligent terminal of supporting video, realize write-in functions, need again the video superimpose chip that the address information of itself is passed to RAM, by RAM, self-built word-base chip is exported in the address of correspondence, complete the function of reading, such two different chips can produce address conflict to the RAM read-write.Adopt a kind of special address switchover mode to make common single port RAM can complete the function of expensive dual port RAM, two group of seven bit address bus in the intelligent terminal of support video received on two alternative chips, and the address bus of work is by the output terminal (AY6~AY0) be switched of alternative chip.When single-chip microcomputer write the offset address of character in the RAM, the gating signal 257WR of alternative chip was low level, and AA6~AA0 is selected for the single-chip microcomputer address wire; When passing through the video superimpose chip from the ROM sense data, alternative CE signal 257WR is high level, the address wire AB6 that just becomes the video superimpose chip that at this moment works in system~AB0.
Power-down protection circuit:
Supporting will have power-down protection circuit in the intelligent terminal of video, and namely the offset address of external a slice FLASH ROM store character in character library prevents the generation of this situation.Because show 12 pages of short messages, the pattern of chip is selected again to maximize, and namely every page shows 128 different characters.Single-chip microcomputer stores them in RAM outside sheet in FLASH ROM sending the character offset address, when the restart routine initialization, information before the power down of automatically reading to preserve in flash memory, and empty outside FLASH ROM in deletion information, so just realize online burning, solved the problem of power down drop-out.
Character stack and position control circuit:
Support in the intelligent terminal of video, selected max model to show character, namely every page can be superimposed with 8 (OK) * 16 (row)=128 a different character, so three mode line sel2~sel0 of video superimpose chip connect high level; The signal of the character output terminal Dout of video superimpose chip is subject to the control of a switch triode Q1, and on the vision signal of the input that is added to, potentiometer W4 is used for regulating the brightness of character stack; Two the potentiometer W1 and the W2 that are connected on the monostable chip by adjusting can change respectively the horizontal and vertical display position of character on screen; Potentiometer W3 on the self-sustained oscillation loop regulates the width of character.Can also change the character supercircuit and change display format, such as character is presented on black screen, only needs to increase a commutation circuit external signal is turn-offed, change the demonstration blank screen into, remake the character stack and get final product.
