Working method between main frame and the extension set,, both can adopt the host query mode, also can adopt extension set warning (interruption) mode, the utility model is with the extension set warning working method brief description course of work.

Warning extension set IC1, with the P1 mouth connected＜normal,＜maintenance 〉,＜power fail 〉,＜high pressure the phase failure 〉,＜power the phase failure 〉,＜power electric leakage 〉,＜illumination fracture of wire 〉,＜illumination electric leakage〉end, carry out binary coding by its physical location, be respectively FEH, FDH, FBH, F7H, EFH, DFH, BFH, 7FH, be stored in the data buffer 40H of internal memory RAM---47H unit, and＜power fail 〉,＜high pressure the phase failure 〉,＜power the phase failure 〉,＜power electric leakage 〉,＜illumination fracture of wire 〉,＜illumination electric leakage〉report to the police,＜power fail〉right of priority is the highest, reduces successively (software realization).With this extension set coding (extension number), two bytes are stored in 30H, the 31H unit of RAM, and make the extension set coding consistent with the host keyboard coding, key assignments equals the row value and adds train value, the extension set binary coding promptly equals the main frame key assignments, can change, and when digital host shows extension number, then should in program, make the key assignments sign indicating number convert decimal code to and show by table-look-up instruction.General＜powered remote control is opened 〉,＜lighting remote controlled opening〉key assignments code (respectively accounting for a byte) is stored in R0 (00H), the R1 (01H) of RAM general-purpose register, so that main frame uses when sending out remote signal.

The IC2 of main frame opens up extension number code storage district at internal memory, is 15 extension sets if any 15 switchgear buildings, then opens 30H---the memory block (each extension number two byte) of 30 unit of 4DH, deposit 15 extension sets codings, and other gets 4EH, 4FH makes buffer.The 2nd, the fault code area, eight dummy cells of 50H---57H reach in order to depositing power failure＜normal 〉,＜maintenance〉code.The 3rd, the remote control mode district, R1 (00H), two unit of R2 (01H) are stored in [powered remote control is opened] and [lighting remote controlled opening] key assignments code.R3 (02H) deposits＜forbids〉code.Other gets R4 (03H) and uses as scan counter.

The extension set master routine is that scan round P1 mouth is every, and during non-fault, everybody is 1, when breaking down, corresponding position is 0, transmits and penetrates subroutine, gets the extension set coding of 40H, 41H unit successively and 30H---the number of corresponding failure address location among the 37H (being failure code) send totalizer A, send P31 (TXD) with A, launch by radiating circuit, simultaneously, failure code is exported by the P2 mouth, sound and light alarm is so that maintenance.

Main frame receives alerting signal, and is temporary, gets the first two byte (extension number) and send totalizer A, get (30H) successively---(4DH) send A, carry out the XRL logical operation, relatively be zero with its negate (needing noble potential output when showing), and be stored among 4EH, the 4FH, in order to showing, this is the affirmation process, if non-vanishing (emission is described or receives wrong), main frame is promptly transmitted automatically and penetrated the subroutine inquiry, the extension set that breaks down receives promptly and retransmits that main frame is heavily received.After the affirmation, promptly from reception buffer, get failure code and send A, negate, again it is sent failure code register 50H---among the 57H one, in order to showing, change display subroutine afterwards, by P1.7 output scanning voltage, the BG4 conducting, send the output of P2 mouth with (4FH), show a position, P1.6 output scanning voltage, send the output of P2 mouth with (4EH), show ten, again by P1.5 output scanning voltage, BG6 conducting, with address (50H)---one numerical value (failure code) in (57H) send the output of P2 mouth, the dependent failure pilot lamp is bright, and scanning output is by the control of R4 register shift, as seen, each warning, address 4EH, content in 4FH and the failure code register all need rewrite.Simultaneously, program makes P3.5 that output be arranged, and makes the loudspeaker warning of sounding, and can stop by it by [forbidding] key.Print then by the printout of [printing] key as need.

When main frame receives power leakance electric alarm or power for illumination leakage-current alarm, should launch remote control and open signal: press assignment key A → press figure key (extension number) → again to press power remote control key point B or lighting remote controlled key point C, launch (subsequently can the scene of sending someone check touch the electric leakage reason).

Extension set is received remote control and opened signal, and is temporary, gets the first two byte successively and send totalizer A, and send A with (30H), (31H), and relatively be zero, promptly confirm as this extension set of remote control, then change the remote control open routine, get working storage the 3rd byte and send A, the numerical value of getting R0, R1 successively send A comparison, and being confirmed to be remote controlled powered establishing by cable still is that the remote control illumination is established by cable, then, by P3.4 or P3.5 output noble potential, make triode BG2 or BG3 conducting, work is started in the realization remote control.
