Embodiment

Most preferred embodiment of the present utility model is such.With reference to Fig. 1-Fig. 5, detect resistance change amount in the life net with the electronics bridge diagram, thereby reach the purpose of alarming anti-theft.Be to turn to various floral designs arbitrarily in the life net by a thin high resistance measurement silk series connection of children, make the interior any place of whole life net trigger alarm set point, because the resistance wire of life net can not split off, or certain section short circuit or human body touch resistance wire electric conductor, otherwise report to the police immediately.Antitheft life net is mounted in outside window, the anti-theft net of making as conventional stainless steel and iron bar, the robber at first will destroy antitheft life net before going into window, and the alerting signal of antitheft life net was not reported owner and operator on duty already and performed antitheft reply and prepare when the robber also prized window.Whole antitheft life net comprises by high resistance measurement silk screen I (1,6), the detection of electronics electric bridge II (2), operational amplification circuit III (3), audio alarm IV (4), PT2262 integrated wireless emission V (5) and forms, and be installed on window frame or the doorframe.Turn to silk screen with high resistance measurement silk (1,6), the silk screen eye can have grid, also straight lattice can be arranged, various silk screens such as rectangle, prismatic, rectangle.With inorganic or organic synthesis material, the synthetic equivalent R of material such as synthetic carbon film, thermal decomposition carbon film, metal film, metal oxide film, chemical deposited film, metal nitride film, piece metal film, metal glaze, system is used for antitheft life net.Film in silk screen or metal material top layer with the high resistance measurement material, also available high resistance measurement material is soaked in the metal nexine, detects emit signal by circuit computing and reaches to report to the police or trigger burglary-resisting system and work when these retes or nexine high value electronic material are damaged promptly.Specifically be with reference to Fig. 1, turn to antitheft life net with high resistance measurement silk (6), the extension line of high resistance measurement silk (6) (45,46) is connected on the electronics electric bridge respectively and detects input end X, Y (26,27), detect II (2), adjust locking through the electronics electric bridge again, when the output of the resistance of extension line (45,46) changes positive negative error 5% (its sensitivity can be adjusted), trigger executive circuit through operational amplification circuit III (3) audio alarm IV (4) is provided power supply, trigger coding emission integrated PT2262V (5) simultaneously.With reference to Fig. 2, antitheft life net window frame (44) is made with insulator or plastic-steel material, scurry the anti-theft wire that is being connected in series the high resistance measurement silk in insulating material window bar (43) contains, window bar should be to make with plastic-steel or insulating material, and every window bar bearing pressure optimum value can be selected for use about 25kg-50kg.Window frame (44) and insulator or plastic-steel material (41) but mixed injection molding or plastic-steel combination.High resistance measurement silk (6) is resistance wire or the resistance material (comprising film, coating, wire rod, sheet material) that is wound in the antitheft life net grid.With reference to Fig. 3, form bridge diagram by antitheft resistance wire (42) with adjustable resistance W1 (28) and resistance R 1, R2, R3 (8,14,32) diode D1, D2, D3, D4 (9,13,29,31), by triode BG1 (11), triode BG2 (30), diode D5, D6 (12,10), resistance R 4 (16) is formed the output of electronics electric bridge.Triode BG3, BG4 (18,35), capacitor C 2, C3 (34,37), resistance R 5, R6, R7 (19,20,36) form operational amplification circuit.Form executive circuit by resistance R 8 (38), diode D7 (21), coiling group coil groups Q1 (22) and MDR (23), the warning power supply is provided and triggers coded telecommand emission integrated wireless emission PT2262 (39).C (47) is a human body touch sensitivity adjustment electric capacity, and W2 is adjustable resistance (17).It is such that the utility model is installed and used, and arranges the high resistance measurement silk or connect various electric elements with conductor wire in the life net grid.Synthesize the various netted or patterns of braiding with the form that injection moulding is sprayed paint.Resistance material with non-wirewound system mixes the life net that causes.For example make the electric conductor of shapes such as bar, side, circle with synthetic materials such as organic or inorganics, or the conductive material that sprays, plates, is fired into.Put into resistance wire or components and parts or synthetic R material and to carry out injection moulding in the mould, punching out becomes or turns to the antitheft life net of various floral designs.At existing antitheft or antitheft door net, spraying or wrapped being covered with on the grizzly bar.This antitheft life net can an independent usefulness, also can a plurality ofly be connected in series and share a burglar alarm life net.Outer or destroy when impaired when the external high resistance measurement that touches, the resistance value of life net output is changed, other Circuits System work generation signal and handling is reported to the police or is opened other burglary-resisting system work afterwards, reaches the alarming anti-theft purpose.Each electric elements of this antitheft life net of reporting to the police connect and connect by Fig. 3 circuit.Connect with W1 by alarming anti-theft resistance simultaneously and be combined into a resistance R, bridge diagram W1 is the correcting potential device, form the R electric bridge by W1R1, R2, R3, R4, form the output of electronics electric bridge by BG1, D5, D1, D2, BG3, D6, D3, D4, R4, be damaged when the alarming anti-theft resistance wire resistance of W1 is changed, make A, B point produce potential difference (PD), thereby make BC1, BC2, the electronics bridge diagram of being formed is by positive potential of R4 output.No matter that is positive negative potential for an A-B point current potential, but the R4F point all is positive potential output.No matter the alarming anti-theft resistance of W1 series connection is open circuit or short circuit, the R4 output of this electronics electric bridge can both guarantee it is positive potential output.W2, C2, BG3, BG4, R5, R6, R7, C3 form operational amplification circuit, and W2 is the adjustment potentiometer that sensitivity is amplified in this computing.R8, MDR, D7, Q1 form executive circuit, after R4 has positive potential output, amplify the BG4 emitter through computing and just produce a positive potential through the conducting of R8 triggering MDR controllable silicon, make the adhesive of Q1 relay, the contact of the contact Q1K of relay becomes conducting by separation, triggers the work of integrated wireless emission PT2262 coded set electricity, sends wireless alarm signal, and by negative electricity of MDR controllable silicon anode output, for alarm bell warning power supply.
