Embodiment

In the utility model, as shown in Figure 1, by 220 volts of civil powers through power transformer B ₁, step-down is 12 volts of alternating currents, again through D ₁～D ₄(1N4007) bridge circuit rectification, capacitor C ₁Become DC current after (220 μ F25V) filtering, electric current is through current-limiting resistance R ₁(10～20Q2W), unilateral diode D ₆(1N4007) out-put supply, (80～120dB) indoor call alerts devices (6) provide the steady operation power supply to give (T-125) digital wireless remote control segmentation receiver (1), (NS-1100) human inductor (2) and Y on the one hand; Give on the other hand and prevent to stop the go-home accumulator E of civil power _cThe 12V dc-battery carries out frivolous charging effect, to guarantee the circuit normal power supply.When door is opened, i.e. K switch ₁(or K ₂) when being switched on, relay J is passed through in its loop ₂(HH52P) normally closed switch J _2KBe connected on relay J ₁(HH52P) normally closed switch J _1KWith the AB terminal shortcircuit, force hands-free switch (4) short circuit with telephone set (5), telephone set (5) work, electric current will be from the C point in delay circuit Fig. 3 again of flowing through behind the switch (3) of the Q point the telephone set (5), when the C point has had electric current to pass through, through time delay resistance R ₂(18KQ) give capacitor C ₂(100 μ F25V) charges, etc. capacitor C ₂The end charging, when voltage rises to 1 volt, triode BT (C9014) conducting, collector and emitter have electric current to pass through thereupon, and at this moment the coil L of reed switch relay (7) (2000 circle) has electric current by producing magnetic field, makes the K switch of reed switch relay (7) ₃Two ends E, D are held by the switch (8) that redials that short circuit goes to trigger telephone set (5), and telephone set (5) is remembered in advance at interior number aut sign to master cellular phone.In like manner, in the people entered fence coverage, human inductor (2) output terminal was exported noble potential, was connected in parallel on the relay J of output terminal like this ₃Action drives switch J _3KShort circuit is held to opening by telephone work through A, B.G, H are in parallel with the hands-free switch of telephone set (5) power supply (4); Q, M are in parallel with telephone set (5) circuit work power; The Q point is telephone set (a 5) base plate cathode power supply, and the M point is telephone set (a 5) base plate negative power supply, and W, I are the binding post of microphone MIC.Switch (3) makes the delay circuit among Fig. 3 rise to delay time and works about 1 second when connecting, telephone set (5) becomes time-delay from dialling device, can work as the use of regular phone machine after closing.Fig. 1 repeat circuit J ₁Effect be when owner will open the door, by connecting digital wireless remote control transmitter switch, instruct digital wireless remote control segmentation receiver (1) output terminal relay J ₁Action, thus drive its normally closed switch J _1KThe AB loop is cut off in action, thereby when guaranteeing that owner opens the door, circuit does not produce false alarm.Indoor warning instructs digital wireless remote control segmentation receiver (1) to make relay J by connecting digital radio remote control switch transmitter ₂Work drives relay J _2KAction is cut off the AB loop, contact J _2KTurn to O road closure, draw the alert loop of circular, when opening door, K switch ₁, K ₂When being switched on, indoor call alerts device (6) work.Or enter in (NS-1100) human inductor (2) fence coverage as the people, make the relay J of (NS-1100) human inductor (2) ₃The output noble potential makes switch J _3KCall alerts device (6) is also worked in the closed-chamber.In case when occurring stopping civil power, circuit is transformed into powered by direct current automatically, enter on the alertly, realize non-stop run.
