After the 1st pin of single-chip microcomputer, the 2nd pin, the 3rd pin, the 4th pin, the 5th pin and the 6th pin detect all states, comprehensive above-mentioned B, C, D condition, single-chip microcomputer does not send the lamp working that dialing instruction single-chip microcomputer makes photoelectric alarm circuit 7, and expression is broken down.
Three, big upright line Guo Zelintaiqu generation circuit is stolen:
1, when the o line is disconnected earlier:
The outage of A:o line disconnects 220V relay coil JKB, b, the energising of a two lines make 380V relay coil JKA closure, at this moment, relay coil JKD outage control its switch KD closure makes node P1 be connected with P2,6V battery discharging, but because node P2 will pass through P8, P9, KB1, P11 or P8, P9, KA6, P11 relay coil JKC is got, because KB1 disconnects, the KA6 closure, relay coil JKC both sides still get electric by a loop, the coil closure.
B: power control loop is in closure state, and open the contact of KB4, the closing of contact of KA3, and the closing of contact of KC3, and the contact of three switches is connected in parallel, so power control loop is in closure state.
C: the control loop that resets is in off-state, and open the contact of KB3, the closing of contact of KB3, and the closing of contact of KC2, and three switch contacts are connected in series, so the control loop that resets is in off-state.
D: trigger control loop and be in closure state, the closing of contact of KA5, open the contact of KB2, and two switch contacts are connected in parallel, and is in closure state so trigger control loop.
After the 1st pin of single-chip microcomputer, the 2nd pin, the 3rd pin, the 4th pin, the 5th pin and the 6th pin detect all states, comprehensive above-mentioned B, C, D condition, single-chip microcomputer are sent the loudspeaker work that dialing instruction single-chip microcomputer makes the lamp working and the sound warning circuit 6 of photoelectric alarm circuit 7.
2, when the disconnected earlier situation of the earlier disconnected identical o line of c line:
3, still analyze when the b line is earlier disconnected: power control loop is in closure state, trigger that control loop is in closure state, the control loop that resets is in off-state.Single-chip microcomputer sends the loudspeaker work that dialing instruction single-chip microcomputer makes the lamp working and the sound warning circuit 6 of photoelectric alarm circuit 7 according to above-mentioned information.
4, when the disconnected earlier situation of the disconnected earlier identical b line of a line.
5, when the people opened the electronic box of jack star by force, the travel switch 10 behind the jack star electric door transferred off-state to by original closure state, was equivalent to the disconnected earlier situation of c line.Automatic dialing alarm immediately.
