Embodiment

Shown in Fig. 1; The alarm of note-book computer device comprises notebook computer, is made up of power supply, cryptochannel, probe, warning circuit and dial-up circuit; Connect through lead therebetween, power supply, cryptochannel, probe, warning circuit and dial-up circuit are installed in notebook computer casing inside.Power supply is made up of 5V three ends fixing output integrated regulator and a ceramic disc capacitor, connects through lead therebetween.Cryptochannel is made up of three power supply toggle switches; Connect through lead therebetween; When three power supply toggle switches are installed in notebook computer casing inside; Should stir handle to it and be exposed at the notebook computer casing outside, be beneficial to regulate the power supply toggle switch from the notebook computer casing outside through stirring handle.Probe is made up of a universal mercury cut-off, a resistance, an one-way SCR and a relay, connects through lead therebetween.Warning circuit is made up of a warning integrated circuit, a PNP triode and a loudspeaker, connects through lead therebetween.Dial-up circuit is made up of a resistance, a switch diode, an adjustable resistance, an electrochemical capacitor, a time integrated circuit, two relays, a silicon rectifier diode and a mobile phone, connects through lead therebetween.

Shown in Fig. 2, G is the battery of notebook computer.Form power supply by 5V three ends fixing output integrated regulator A1 and ceramic disc capacitor C1.Form cryptochannel by three power supply toggle switch SA, SB, SC, SA1, SA2, SA3, SA4, SA5, SA6, SA7, SA8, SA9 are nine power contacts on the SA; SB1, SB2, SB3, SB4, SB5, SB6, SB7, SB8, SB9 are nine power contacts on the SB; SC1, SC2, SC3, SC4, SC5, SC6, SC7, SC8, SC9 are nine power contacts on the SC.By universal mercury cut-off SQ, resistance R 1, one-way SCR VS and relay K 1 are formed probe.By warning integrated circuit A2, PNP triode VT and loudspeaker B form warning circuit.By resistance R 2, switching diode VD1, adjustable resistance RP; Electrochemical capacitor C2, time integrated circuit A3, relay K 2, K3; Silicon rectifier diode VD2 and mobile phone A 4 are formed dial-up circuit; 1,2 leg of A4 are respectively positive source and the negative input of A4, and what A4 was last 3 is numerical keys 3 of A4, and the last KG of A4 is the switch switch of A4.When the power supply of G output gets into A1, can be stabilized in 5V, the effect of C1 is a transient response of improving load.The 5V power supply is imported SA, SB, SC through lead.When the 5V power supply gets into SA; Because the SA1 of SA, SA2, SA4, SA5, SA6, SA7, SA8, SA9 are through the mutual UNICOM of lead; Therefore the handle of stirring that needs only SA pushes any one power contact among SA1, SA2, SA4, SA5, SA6, SA7, SA8, the SA9; The 5V power supply all can be supplied power to subsequent conditioning circuit, because SA3 is not and other eight power contact UNICOMs, so during with the stirring handle and push SA3 of SA; The 5V power supply just can not supplied power to subsequent conditioning circuit, has so just formed a password figure 3; When the 5V power supply gets into SB; Because the SB1 of SB, SB2, SB3, SB4, SB5, SB6, SB8, SB9 are through the mutual UNICOM of lead; Therefore the handle of stirring that needs only SB pushes any one power contact among SB1, SB2, SB3, SB4, SB5, SB6, SB8, the SB9; The 5V power supply all can be supplied power to subsequent conditioning circuit, because SB7 is not and other eight power contact UNICOMs, so during with the stirring handle and push SB7 of SB; The 5V power supply just can not supplied power to subsequent conditioning circuit, has so just formed a password figure 7; When the 5V power supply gets into SC; Because the SC1 of SC, SC2, SC3, SC4, SC6, SC8, SC7, SC9 are through the mutual UNICOM of lead; Therefore as long as during with the stirring handle and push any one power contact among SC1, SC2, SC3, SC4, SC6, SC7, SC8, the SC9 of SC; The 5V power supply all can be supplied power to subsequent conditioning circuit, because SC5 is not and other eight power contact UNICOMs, so during with the stirring handle and push SC5 of SC; The 5V power supply just can not supplied power to subsequent conditioning circuit, has so just formed a password figure 5; Effect through SA, SB, SC will form password 375 like this, know as the user under the situation of password, and input password 375, the 5V power supply just can not supplied power to subsequent conditioning circuit, thus the utility model can not reported to the police.When use is set up defences, any power source contact beyond the password that handle pushes setting of stirring of SA, SB, SC, subsequent conditioning circuit will be in electricity condition.After the 5V power supply of SA, SB, SC output gets into subsequent conditioning circuit, the 5V power supply through VD2 to A4 power supply make it to be in electricity condition because VD2 has the pressure drop of 0.8V, the supply voltage that gets into A4 like this is exactly 4.2V; When VD2 was to the A4 power supply, RP charged to C2 at the 5V power supply, and when just beginning, the 2nd pin of A3 is an electronegative potential, and A3 set makes its 3rd pin output noble potential, and it is closed that the K3 that continues gets its normally opened contact of electric adhesive; After 10 seconds, C2 upper extreme point position (i.e. the 6th pin current potential) rises to three of supply voltage/two o'clock, and A3 is reset, its 3rd pin output electronegative potential, and then the K3 dead electricity is broken off; Because being the normally opened contacts through lead and K3, two power contacts under the KG key of A4 link to each other; So at its 3rd pin output noble potential of A3 set; K3 gets its normally opened contact of electric adhesive in 10 closed seconds; Two power contacts under the KG key of A4 also can UNICOM, is equivalent to the human hand by 10 seconds of KG key, and A4 will Auto Power On and is in holding state like this.After A4 was in holding state, if there is the thief to steal when moving notebook computer, SQ will rock, and its internal water silver tipped contact will be connected moment, after the moment connection of SQ internal water silver tipped contact, will trigger VS through R1, and it is closed that the K1 that continues gets its normally opened contact of electric adhesive.After K1 got its normally opened contact closure of electric adhesive, the KI normally opened contact of 5V power supply after getting electric closure given its follow-up circuit supply; The A2 that continues gets the electrician and does, and from its 2nd pin output audio signal, the sound signal of output will drive B and send loud alarm sound through the VT power amplification; When A2 got electrician's work, it is closed that K2 also can get its normally opened contact of electric adhesive.Because being the normally opened contacts through lead and K2, two power contacts under 3 keys of A4 link to each other; So after K2 got its normally opened contact closure of electric adhesive, two power contacts under 3 keys of A4 also can UNICOM, is equivalent to pushing 3 keys by A4 of human; Like this; Because the signal-key dialing function of A4, the telephone number that is stored under 3 keys will be dialed away, notifies the user alert.Effect through above circuit when the utility model just can have alert after setting up defences, has had the function of audible alarm and dialing alarm.In actual use, through changing the last power contact of SA, SB, SC and the mode of connection of circuit, just can form different ciphers.

In Fig. 2, G is the battery of notebook computer.The A1 model is 7805, and A2 is a LC170 type warning integrated circuit, and A3 is 555 type time integrated circuits, and A4 is a mobile phone.The C1 specification is 0.1UF, and the C2 specification is 25V10UF.SA, SB, SC are the small power supply toggle switches with nine power contacts.SQ is small-sized universal mercury cut-off.The R1 resistance is 3K, and the R2 resistance is 2K, and RP is the 1M adjustable resistance.The VS model is MCR100-1.K1, K2, K3 are 4100 type 5V relays.The VT model is 9012.B is 8 Ω, the small-bore coil-moving speaker of 0.25W.The VD1 model is 1N4148, and the VD2 model is 1N4001.
