Abstract
The utility model relates to a vigilance speech reminding circuit in the field of safety precautions. The technical proposal is that: the utility model consists of a human body passing through circuit that comprises resistances R1 and R2, an infrared light emitting diode D and an infrared photosensitive triode LD and a delay control circuit that consists of a capacitance C, a resistance R3 and triodes BG1 and BG2; the collector of the triode BG2 is connected with a speech chip IC and a horn L. The utility model has the advantages of simple structure, convenient to be arranged. When arranged in public places, the utility model can perform the function of safe and effective speech reminding.
Description
Technical field
The utility model relates to a kind of warning voice warning circuit in safety precaution field.
Background technology
The alert license bearing of safety miscellaneous is all placed in present tourist attractions, bank and many danger zones, but adopt the literal alerting pattern of various materials mostly, with the passage of time its literal can come off, many do not read or people that eyes are bad just not can obtain prompting arranged again, often cause many unnecessary accidents.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, provide a kind of can be with language from the moving warning voice warning circuit that gives a warning
Its technical scheme is: form human body through testing circuit by resistance R 1, R2, infrarede emitting diode D, infrared phototriode LD; Form delay control circuit by capacitor C, resistance R 3 and triode BG1, BG2; The collector of triode BG2 connects speech chip IC and loudspeaker L.
The utlity model has simple in structurely, convenient by dress, in the public arena of needs it is installed, can play safe and effective voice suggestion effect, people's safety is secure greatly.
Description of drawings
Accompanying drawing is the circuit theory diagrams of a kind of embodiment.REN refers to human body among the figure; D, LD are that infraluminescence, photosensitive transmitting-receiving are to pipe; IC is speech chip (existing product); L is loudspeaker.
Embodiment
Be further described with regard to its principle of work below in conjunction with accompanying drawing: device installs and opens K switch, when nobody crosses warning line usually, do not block owing to have between the infrarede emitting diode D, infrared phototriode, so triode BG1, BG2 end IC non-transformer loop and not working.If when someone crosses warning line, block owing to produce between infrarede emitting diode D, the infrared phototriode, so triode BG1 is by also charging to capacitor C rapidly by becoming conducting, simultaneously, triode BG2 conducting IC obtains electric power loop and works, and loudspeaker send the caution voice, the warning line even if the pedestrian speeds away, because the effect of capacitor C, resistance R 3, sound circuit also can be worked a period of time, so that enough informations to be provided.
Claims (1)
1. the warning voice warning circuit is characterized in that: connect to form human body through testing circuit by resistance (R1, R2), infrarede emitting diode (D), infrared phototriode (LD); Connect to form delay control circuit by electric capacity (C), resistance (R3) and triode (BG1, BG2); The collector of triode (BG2) connects speech chip (IC) and loudspeaker (L).
