Summary of the invention
The purpose of this utility model provides a kind of simple in structure, anti-invasion intelligent alarm protective guard that safeguard function is strong.
For achieving the above object, the utility model adopts following technical scheme:
Anti-invasion intelligent alarm protective guard described in the utility model comprises the fence body of being made by insulation materials and metal tube, it is characterized in that: be provided with three in the metal tube of fence body and establish alert line, wherein two ends of establishing alert line are electrically connected, other has two high-tension electricity polar curves to be electrically connected with the metal tube that is provided with at interval respectively, have junction box on the fence body, this junction box with establish alert line and the high-tension electricity polar curve is electrically connected.
Have warning circuit in the above-mentioned junction box, this warning circuit comprises control circuit and is connected the sound circuit and the high-pressure generating circuit of the controlled end of control circuit, the trigger end of control circuit respectively with establish alert line and be connected, the high-voltage output end of high-pressure generating circuit is connected with the high-tension electricity polar curve.
Between control circuit and high-pressure generating circuit, also be connected with delay circuit.
After adopting technique scheme, the wire netting body constitutes the protection of first road, when the people cuts off fence, the alert line of establishing that is embedded in the metal tube is experienced extraneous variation and is sent signal to junction box, control circuit control alarm buzzer in the warning box sends chimes of doom, high pressure generator produces high voltage, on fence, produce electric spark, constitute the protection of second road, alarm call can be put through the telephone number that the user presets simultaneously, when reporting to the police, criminal is played the effect of deterrence, reach the purpose of prevention criminal invasion and remote alarms.
Description of drawings
Further specify the utility model below in conjunction with drawings and Examples:
Fig. 1 is the sectional view of the fence body of an embodiment of the present utility model;
Fig. 2 is the circuit diagram of the junction box of an embodiment of the present utility model.
The specific embodiment
As shown in Figure 1, the housing of fence body adopts insulation materials manufacturings such as plastics, 1, three of some metal tube longitudinally is installed on the housing is established alert line A, B, C and pass from metal tube 1, and the metal tube 1 that is provided with is connected with two high-tension electricity polar curve D, E respectively at interval.
As shown in Figure 2, if alert line A, establish alert line B, establish alert line C and be connected with three points of A1, B1, C1 in the junction box respectively by jack, triode BG1, BG2, BG3 and peripheral circuit thereof constitute control circuit, speech IC IC1 and peripheral cell thereof constitute sound circuit, and high pressure generator and peripheral cell thereof constitute high-pressure generating circuit.The control output end of control circuit is connected to the power input (i.e. the 1st, the 2nd pin) of speech IC IC1.The base stage of triode BG1 is connected to the B1 point by resistance R 1, and emitter stage is connected with the power end of speech IC IC1, is connected to the A1 point by resistance R 3 simultaneously.The base stage of BG2 is received the emitter stage of BG3, and the base stage of BG3 is connected to the emitter stage of BG2 and is connected with the emitter stage of BG1, is connected to the negative pole of power supply simultaneously again by capacitor C 5.The colelctor electrode of BG2 is by establishing the positive pole that alert K switch is connected to battery pack, and the base stage of BG2 is connected on the colelctor electrode of BG1 by capacitor C 4 and resistance R 4.The colelctor electrode of BG3 is connected to the emitter stage of triode BG4 by resistance R 5 and is connected to the negative pole of battery pack simultaneously, and the base stage of BG4 is connected with the 4th pin signal output part of speech IC IC1, and the colelctor electrode of BG4 is connected to the positive pole of battery pack by loudspeaker Y.
A1 in circuit diagram, C1 point is by establishing alert line short circuit, and when the B1 point was unsettled, the 1st, the 2nd pin of speech IC IC1 can not get operating voltage, can not send signal; During A1, C1 point open circuit, A1 point current potential raises, triode BG3 conducting, and the base potential of BG2 reduces, triode BG2 conducting.The the 1st, the 2nd pin of speech IC IC1 obtains positive voltage and works, and from the 4th pin output alarm signal, the 3rd pin output control signal, the alarm signal of the 4th pin output promotes loudspeaker Y and sends alarm sound after triode BG4 amplifies.After speech IC IC1 gets electric work, even short circuit A1, C1 point once more, it is quit work, because the base stage of BG3 is directly received the power end of speech IC IC1, and the A1 point is the base stage that is connected to BG3 by resistance R 3, even the short circuit once more of A1, C1 point, the voltage of power end still exists.
The 3rd pin signal output part of speech IC IC1 is connected to the base stage of switch triode BG5 by resistance R 6, the emitter stage of BG5 connects the negative pole of battery pack, collector connecting relay J1 receives the earth terminal (1 pin) of IC 2 simultaneously, and the control end of relay J 1 can be used for controlling alarm call and dial the telephone number that presets when meeting accident.
Be the direct current that obtains about 12V after the rectifier bridge rectification formed by transformer B1 step-down, diode D2-D5, capacitor C 6 filtering in addition by one tunnel AC power, its ground wire links to each other with the negative pole of battery pack, and+12V end is connected to the 4th pin and the 8th pin of relay J 1 and high pressure generator G and IC 2.IC 2 and peripheral circuit thereof and the relay J 2 that is connected between its 1st pin and the 3rd pin have constituted delay circuit, make IC 2 prolong a period of time trigger relay J2 again after the electric work, and the power supply of the logical high pressure generator G of controlled termination by relay J 2.The controlled end J2-1 of relay J 2 connects the power input of power supply+12V end and high pressure generator G, and output D1, the E1 of high pressure generator is connected respectively on high-tension electricity polar curve D, the E.
When the fence body destroyed, if the annexation of alert line A, B, C changes, the power supply of on-delay circuit when control circuit control sound circuit sends alarm sound, relay J2 action after prolonging a period of time, connect the power supply of high pressure generator G, produce high-voltage arc between metal tube 1, the deterrence criminal must not be close.
IC 1 in the present embodiment is that model is the speech IC of K9561, and the model of IC 2 is NE555.
