Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, a kind of acousto-optic voice alarm safe fence described in the utility model, it mainly comprises the guard rail of at least two guard rails or a disjunctor, described guard rail is separately installed with and adopts infrared opposite-radiation module to block protection zone, infrared emission unit 1 and supporting infrared receiver 2, described infrared emission unit 1 is by infrared transmitter 3, warning alarm module 4 and battery module 5 form, described infrared receiver 2 is by supporting with infrared transmitter 3 and receive the infrared remote receiver 6 of infrared signal, voice recording-reproducing assembly 7, warning alarm module 4 and battery module 5 form, warning alarm module 4 wherein in infrared emission unit 1 is attached to and is controlled by often opening or normally closed Controlling vertex of infrared receiver 2.
Shown in Fig. 3,4, the voice recording-reproducing assembly in described infrared receiver comprises: the ISD1820 selected employs chip, and by the TDA2030 power amplifier chips and the playback that are connected with 8 Ω/8W supersound projectors be connected; Warning alarm module in described infrared emission unit and infrared receiver is all selected can at the highlighted LED array of Chang Liang and flicker two kinds of MODE of operation as warning lamp.
Described infrared emission unit and infrared receiver be separate configurations battery module all separately, and this battery module adopts 4 3.7V/1500mAH high-performance lithium batteries, and is configured with external power supply adapter as charging device; The warning lamp of described warning alarm module is configured with the better taper reflection lampshade of alarming effect.
Safe fence adopts infrared opposite-radiation to detect when having people or foreign matter swarms into by infrared transceiver module 1, the ISD1820 controlling voice recording-reproducing assembly 2 employs the supersound projector of chip, TDA2030 power amplifier chips and 8 Ω/8W, the one section of voice recorded before broadcasting are reminded, control the highlighted LED array of warning lamp module 3 simultaneously, carry out flicker to report to the police, warning lamp module 3 configures taper reflection lampshade, makes alarming effect better.The power supply of whole system is provided by 4 3.7V/1500mAH high-performance lithium batteries of battery and charging module 4, and continuous firing reaches more than 12 hours, and charging adopts external power supply adapter.
