The The whole control network that is made of home controlling and the Internet as shown in Figure 1, what adopt in home controlling is asynchronous serial bus communication, it is to be asynchronous serial communication control of every electric equipment configuration in netting, make each electric equipment in the home controlling carry out asynchronous serial bus communication by asynchronous serial communication control through the serial asynchronous communication mouth, this communication structure and mode have existing resource is taken few, characteristics easy to implement, that implementation cost is low.Certainly, also can adopt other communication structure and communication mode.The structure of serial asynchronous communication controller as shown in Figure 2, the formation of serial asynchronous communication controller comprises the sending and receiving part, bus processing section and logic control part, the data buffering processing unit 1 that the formation of sending and receiving part comprises interface end asynchronous serial Transmit-Receive Unit and joins with it; The data buffering processing unit 2 that the formation of bus processing section comprises bus end asynchronous serial Transmit-Receive Unit and joins with it; Logic control partly comprises communication control unit, error count and fault processing circuit, csma conflict monitoring circuit.As shown in Figure 3, the formation of described interface end asynchronous serial Transmit-Receive Unit can comprise interface end asynchronous serial transceiver, the string that joins with transceiver-and change-over circuit and also-string change-over circuit; The formation of described data buffering processing unit 1 can comprise that interface reception data buffer and interface send the data buffer zone; The formation of described bus end asynchronous serial Transmit-Receive Unit can comprise bus end asynchronous serial transceiver, join with it also-string change-over circuit and string-and change-over circuit; The formation of described data buffering processing unit 2 can comprise that bus sends data buffer zone and bus reception data buffer; Described communication control unit can comprise the transmit control register heap, adds up and checking circuit, and the cyclic redundancy code generation circuit receives the control register heap, adds up and generative circuit address check circuit, CRC circuit, time-out check circuit.Again as shown in Figure 4, described interface reception data buffer can comprise data buffer zone 1, interface buffer control circuit 1; Interface sends the data buffer zone can comprise data buffer zone 2, interface buffer control circuit 2; Bus sends the data buffer zone can comprise data buffer zone 3, bus buffer district control circuit 1; The bus reception data buffer can comprise data buffer zone 4, bus buffer district control circuit 2; Receive the control register heap and can comprise that frame tagged word register file 2, interface transmit control register heap, bus receive control register heap, answering circuit 2 and answering circuit 4; The transmit control register heap can comprise that frame tagged word register file 1, interface receive control register heap, bus transmit control register heap, answering circuit 1 and answering circuit 3; Interface end asynchronous serial transceiver can comprise that interface asynchronism transceiver, frame format packeting circuit 1, frame format unpack circuit 1; Bus end asynchronous serial transceiver can comprise that bus asynchronism transceiver, frame format packeting circuit 2, frame format unpack circuit 2.Whole communication controller of serial interface bus can be made into an integrated circuit (IC) chip.Can realize error count and fault processing function with the fatal error testing circuit shown in the accompanying drawing 4 during concrete the making, and-string change-over circuit and string-and change-over circuit can merger unpack in the circuit in frame format packeting circuit and frame format.

The operation principle of communication controller of serial interface bus: the mode that equipment adopts universal asynchronous serial communication sends to the Asynchronous Serial Interface IRX of communication controller of serial interface bus and contains initial symbol, data length, control command word, destination address, data block, verification and and the frame sequence of end mark.Through communication controller of serial interface bus internal interface end asynchronous serial transceiver, be reduced into 8 bit stream, by string-and change-over circuit become parallel data and deposit the interface reception data buffer in.Simultaneously, send and add up and checking circuit, determine whether the transmission data are correct, send the transmit control register heap the result.The transmit control register heap extracts control command word, destination address and transmission data from the interface reception data buffer, and deposit bus in and send the data buffer zone, add local address, by the cyclic redundancy code generation circuit check code is deposited in check field simultaneously, and organize the bus transfer frame.(the bus transfer frame is the frame sequence with initial symbol, destination address, local address, control command word, length, data block, check field and end mark.) according to different control word decisions data to be sent to bus be to adopt the broadcast mode or the mode of intelligence transmission for transmit control register heap, start to send.The signal that collision detection provides according to carrier sense multiple access when being the bus free time, allows to send, and then starts to send.Bus sends the data buffer zone and data is sent also-gone here and there change-over circuit to form serial sequence.Send bus transfer frame through asynchronous serial bus interface BTX to communication bus by bus end asynchronous serial transceiver at last.Adopting the mode of " listening while saying " to determine whether to send successfully in the process of transmitting, specifically is that BRX by the asynchronous serial bus interface receives more whether the bit sequence of the bit sequence that sends to bus and transmission is input to the carrier sense multiple access collision detection circuit consistent.If consistent, then continue to send; If inconsistent then notify transmit control register heap and error count fault processing circuit immediately, stop transmission.If error count is overflowed, then carry out fault processing, stop to send, producing mismark etc.

On the contrary,, at first be input to bus end asynchronous serial transceiver, be reduced to 8 bit stream, send serial-parallel conversion circuit, CRC circuit, time-out check circuit through asynchronous serial bus interface BRX if communication bus is sent a transmission frame sequence.String-also then deposit the bus reception data buffer in after the conversion; The cyclic redundancy check circuit obtains sending reception control register heap behind the result, determines whether transmission frame is effective; The signal whether the time-out check circuit then provides frame sequence to finish can accurately reset whole receiving circuit, enters new wait accepting state.The address check circuit then extracts DAF destination address field and local address relatively from the bus reception data buffer, determine to mail to local transmission frame.Destination address, control command word and data block deposit interface transmission data buffer zone in the control register heap copy bus reception data buffer by receiving.Simultaneously by add up and generative circuit obtain verification and, also deposit interface in and send the data buffer zone.Receive the control register heap and start the interface transmission, interface sends the data buffer zone data and forms 8 bit streams through parallel-to-serial converter, sends into interface end asynchronous serial transceiver and mails to equipment through Asynchronous Serial Interface ITX.

Frame tagged word register file 1 is the result who unpacks according to frame, stores the tagged word of representative frame into the relevant register heap, as command word, frame length, source address, destination address, local update address, local update control register etc.Interface transmit control register heap is when control interface transmission interface buffering area control circuit 2 starts work; Judge that interface sends condition, start to send; Control adds up and generates (adding up and generation module); Control interface frame format packing (frame format packing 1).It is that the verification received frame is corrected errors that bus receives the control register heap, judges frame head, postamble, judges cyclic redundancy code (CRC module), judge information bit length, judge receive time-out (time-out check module), by source address, destination address, the judgment frame sending direction; The audit interface state judges whether to move frame information to interface; When control bus reception data buffer control module 2 starts work.The result that frame tagged word register file module 2 unpacks according to frame stores the tagged word of representative frame into the relevant register heap, as command word, frame length, source address, destination address, local update address, local update control register etc.It is that the verification received frame is corrected errors that interface receives the control register heap, judges frame head, postamble, judges and add up and (add up and check module) that judgment frame length is judged receive time-out (time-out check module); The supervision bus state judges whether to the bus translation frame information; When control interface buffering area control circuit 1 starts work.Bus transmit control register heap is when control bus buffering area control module 1 starts work; Judge that bus sends condition, start to send; The Control Circulation redundant code generates (cyclic redundancy code generation module); Control bus frame format packing (frame format packetization module).The data buffer zone comprises the interface reception data buffer, interface sends data buffer zone, bus reception data buffer, bus transmission data buffer zone 4 block RAMs, and every block size is 8*32bit.The buffering area control circuit is used to produce read-write control signal, the read/write address of data buffer zone (RAM) and empties the buffering area signal.The frame structure parse module is the characteristics according to dissimilar frame structures, and frame data are unpacked.The frame structure packetization module is the characteristics according to dissimilar frame structures, and frame data are packed.Asynchronism transceiver (UART) module is to receive and the standard of transmission start-stop type charcter topology start bit, 8 bit data positions and a position of rest.Sample frequency is ten sixths of interface baud rate.If the charcter topology mistake, interface end abandons automatically; The fatal error of then carrying out bus end detects (fatal error detection module) and replys judge module: the acknowledgement frame that receives is handled accordingly; Check results to non-acknowledgement frame is replied processing accordingly; Chip is provided with frame is replied and warm reset (having only interface that this function is arranged); Start transmission transmission acknowledgement frame (having only bus that this function is arranged) according to bus acknowledge situation control interface.Carrier sense, collision detection module are used for the real-time listening bus, and address priority is judged in collision detection.The fatal error testing circuit is the charcter topology when set form when containing one or more non-tagmeme, then detects a form error, produces bus error (fatal error) when being accumulated to 128 form errors.And control interface transmit control register heap starts interface transmission transmission fatal error frame.

Because in the existing home control system, not idle not the using of full duplex serial communication interface that a programmable UART of having (asynchronism transceiver) function is all arranged in the single-chip microcomputer of each controlling object, therefore with the serial asynchronous communication controller therewith communication interface join, both need not transform existing controlling object, utilized the idle resource of controlling object again, and adopted the serial interface communication mode, line has only several, and adopt the parallel interface communication mode, then need tens.
