Fig. 5. the utility model embodiment synoptic diagram.

See accompanying drawing, a kind of lamination warning archive cabinet, comprise a plurality of joint cupboards, it is characterized in that also being provided with joint cupboard base member case 1 and remote-control burglar alarm, remote-control burglar alarm comprises telepilot 5, receiver 6, alarming horn 7 and power supply 8 and power switch 9, have trigger switch k1, k2 on the interior edge strip 3 of the cupboard doorframe of the superiors joints cupboard 2, the bottom of joint cupboard 2 is provided with plug A1, B1; Have trigger switch K1, k2 on the interior edge strip 3 of the cupboard doorframe of bottom joint cupboard 4, the top of bottom joint cupboard 4 is provided with socket A2, B2 and trigger switch K3, and plug A1, B1 are equipped with in the bottom of bottom joint cupboard 4; In the joint cupboard base member case 1 receiver 6, alarming horn 7 and power supply 8 and power switch 9 are housed, socket A2, B2 and trigger switch K3 are equipped with in joint cupboard base member case 1 top, four pin of joint cupboard base member case 1 also are equipped with trigger switch K4, wherein plug A1, B1 join with socket A2, B2 are corresponding, and trigger switch K1～K4 is connected by plug A1, B1 and socket A2, B2 are parallel; Socket B2 on the joint cupboard base member case 1 connects power cathode, and socket A2 joins through relay J 1 contact and the alarming horn 7 of receiver 6, alarming horn 7 another termination power switches 9.

Have trigger switch k1, k2 on the interior edge strip 3 of the cupboard doorframe of the joint cupboard 10 in the middle of being placed on, socket A2, B2 and trigger switch K3 are equipped with in top, and plug A1, B1 are equipped with in the bottom.

Lamination warning archive cabinet can be formed with two～six joint cupboards.

Trigger switch K3 is equipped with in about joint cupboard top or front and back, also can on joint four corners, cupboard top trigger switch K3 be housed.

Joint cupboard base member case 1 is separated with bottom joint cupboard 4, and joint cupboard base member case 1 and bottom joint cupboard 4 also can be an integral body.

Remote-control burglar alarm, adopt the circuit of Chinese patent 96212492.3, referring to Fig. 3, Fig. 4, remote control alarming unit comprises telepilot 5, receiver 6, power supply 8, power switch 9 and alarming horn 7, telepilot comprise scrambler and self-excited oscillator wherein scrambler by the coding ic chip ₁With timing resistor R ₂Form, self-excited oscillator is by BG ₁, L ₁, C ₁, C ₂, C ₃, R ₃, R ₄Form.Telepilot also is provided with a self-lock switch K, the termination power positive pole of self-lock switch K, and the other end of self-lock switch K also connects voltage stabilizing diode WD and LED, and another termination coded set of WD becomes 18 pin of piece, another termination power cathode of LED.Receiver comprises Armstrong circuit, amplification and rectification circuit, demoder, phase inverter and pilot relay J ₁, the contact of pilot relay J1 is serially connected between trigger switch and the alarming horn 7; In fact Armstrong circuit gets the receiving unit of superregenerative receiver, and it is by R ₅～R ₇, C ₇～C ₁₂, D ₁, L ₂, L ₃And BG ₂Form, receive frequency is by L ₃, C ₇Determine.The coded signal that demodulates is through C ₁₃Be coupled to the amplifier shaping circuit.Amplification and rectification circuit is by R ₁₀～R ₁₂, C ₁₄～C ₁₆, BG ₃And IC ₃Form IC ₃Be the operational amplifier integrated package, play shaping operation at this.Coded signal is through BG ₃Amplification, IC ₃Deliver to decoding integrated package control end IC after the shaping ₂14 pin.At this moment, if signal and demoder coding is identical, IC then ₂17 pin output high level.IC ₂Output terminal through diode D ₂With phase inverter input resistance R ₁₄Connect.Phase inverter is by R ₁₄, D ₃, C ₁₁And BG ₄Form relay J ₁Be the phase inverter load.When pressing self-lock switch K, this moment, a modulated carriers signal was sent in telepilot work, and receiver receives that this modulated carriers signal is through amplifying shaping, if this decoding signals IC ₂Coding and scrambler IC ₁It is identical to encode, then IC ₂Output terminal 17 pin are high level, make BG ₄Conducting, relay J ₁Adhesive, relay J ₁Contact goes to control being switched on or switched off of remote-control burglar alarm, promptly connects and reports to the police or the releasing warning.

The trigger switch that this lamination warning archive cabinet uses is a normally closed push button switch, is in normal open state at ordinary times.When archive cabinet was placed, the trigger switch button of each layer was depressed, and is in normally open, can not send chimes of doom.When moving if any the people, trigger switch K3 button is upspring, and energized is sent chimes of doom.Open the cupboard door if any the people, trigger switch K1, K2 button are upspring, and energized is sent chimes of doom.
