(2), circuit working principle
1, rob, fire, theft, the rescue warning course of work:
Report to the police after the generation, corresponding input port 19,20,21 or 22 one-tenth high level charge to its corresponding electric capacity by resistance R 25, R17, R18 or R19.When charging potential acquires a certain degree, corresponding diode D1, D2, D3 or D4 conducting.Triode T7 drives the T8 conducting by by the end of saturated, and battery B begins to be the entire circuit power supply.Because the auto-lock function of resistance R 23 and diode D8 guarantees the circuit continuous operation.Single-chip microcomputer U2 control U1 reads the state of each input port.The corresponding alert program of starting after automatic program identification.U2 control T6 conducting, the relay J adhesive, telephone line switches on the alarm circuit.U2 control T5 ends, and makes T4, the T3 conducting, and telephone line is through reverse-connection preventing circuit B2 like this, and T3 is added on the DTMF function circuit.Single-chip microcomputer U2 control DTMF function circuit is decided the place and is sent corresponding warning dtmf signal or send the beeper alarm signal to the individual to giving.Afterwards, U2 controls each circuit and recovers ortho states, control T7, and T8 ends.The entire circuit dead electricity, alarm cycle finishes.R11, E2, Z1 provides operating voltage for U3, and T2 and peripheral circuits are the dtmf signal output driving circuit, C1, R5, R4 are the dtmf signal input circuit.
2, the antitheft operation principle of telephone line:
If someone phreaking, its line voltage descends, and the output voltage of bridge circuit B5 also descends thereupon.Transistor T 9 ends by being saturated to, T10, and T11, T12, T13 is conducting thereupon.Electric capacity E12 charging, charging potential raises and makes D6, T7, the T8 conducting, circuit powers on.Control T1 conducting after single-chip microcomputer U2 identification, buzzer B3 pipes, the prompting owner.The DTMF of U2 control simultaneously function circuit sends interference signal to telephone line makes appropriator can not normally dial phone.
3, limit is made a long-distance call or is limit and beat the designated telephone operation principle:
Closing Switch K3 presets this function.When normal use phone, because of bridge circuit B4 in the negative road of disconnecting, so optocoupler O1, O2 is by by the end of conducting, triode T14 conducting is charged to electric capacity E13.Charging potential makes diode D5 after raising, triode T7, and the T8 conducting, circuit powers on.Single-chip microcomputer U2 control DTMF function circuit receives the telephone number that telephone set dials.When differentiating is that U2 control relay J switched telephone line after toll telephone or a certain limit were made a phone call, and telephone set can not use.Then, U2 control each several part circuit recovers ortho states, the circuit dead electricity, and the work period finishes.
4, remote telephone operation principle:
K switch 1 closure, this function presetting.After phone was squeezed into, bell signal was coupled by capacitor C 9, bridge circuit B1 rectification, and electric capacity E14 filtering, and resistance R 3, R45 charges to electric capacity E7.Charging voltage rises and makes D7, T7, and the T8 conducting, circuit powers on.After the single-chip microcomputer U2 identification, control DTMF function circuit sends answer signal to the other side.After the other side receives answer signal, press predetermined number button (remote control of every road all has the predetermined number of oneself).Single-chip Controlling DTMF function circuit receives the signal of sending, and judges the back by analysis by its serial ports P3.0, and P3.1 transmits signal to integrated circuit U4, the work of control corresponding relays.Triode T15, T16, T17, T18 are the drive circuit of each relay, relay is the normal output of making war.The user is remote-controlled to open a certain relay, also remote-controlledly closes a certain relay.Behind the cut-off, U2 control each several part circuit recovers ortho states, the circuit dead electricity, and the work period finishes.
5, other:
Push switch K2, luminous tube L1 is bright.According to its brightness, judge what of battery electric quantity.
Theft-proof sensor is by the door lock initialize switch, and door status switch is formed.Smoke detector is commercially available universal smoke detector.
