The utility model can take alarm actions effectively and visually. The utility model overcomes the defect of the existing static character alarm tablets.
Description
The utility model relates to a kind of voice warn device, is applicable to such as the prompting people to note or the warning place.
Usually in occasions such as warehouse, oil depots,, the labels of warning such as " no smoking ", " No burning " to be installed all in accordance with regulations for the prompting people note taking precautions against fire etc.But for various reasons, this static indicative caution notice can not attract much attention sometimes, and security incident happens occasionally.
The utility model purpose is to provide a kind of and has the warn device of function of voice, so as warning effect of performance effectively, the generation of minimizing security incident.
The technical solution of the utility model is to utilize human body through the infrared sensor warning region, the signal that the infrared ray of being launched by sensor reception human body produces, through amplifying, after shaping and the logical process, the work of driving sound circuit, send such as voice such as " when---no smoking ", " when---No burnings ", play sound effect of warning.This device more can attract much attention than the simple board of warning.Auxilliary driving light indicator illuminates the label of warning, and is more intuitive, clear, play the effect of warning effectively.
Further specify the technical solution of the utility model below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is the circuit structure block diagram of a kind of embodiment of the utility model.
Fig. 2 is the electrical schematic diagram of Fig. 1 embodiment.
Fig. 3 is the electrical schematic diagram of the attached multichannel control alarm of Fig. 1 embodiment.
This embodiment provide one have that voice are warned, comprehensive warn device that light-operated indication and signal send multichannel control warning function.Main circuit is the voice circuit of warning, these voice circuit of warning comprises human-body infrared sensing device (BH), (multistage) amplifying circuit (T1, A1), shaping circuit (A2), the diode (D2) that the output terminal of shaping circuit (A2) passes through connects the input end of signal amplifier (A3) through integrating circuit, it among the embodiment anode of operational amplifier (A3), the signal input part of the output termination speech IC (HFC5225) of signal amplifier (A3), the signal output part of speech IC is by wave filter (C13, R22, R23, C12) connect the signal input part of note amplifier (LM386), audio signal output end connects loudspeaker (SP).For guaranteeing the circuit steady operation, and reduce quiescent dissipation and multiple voice signal function is provided when no signal is imported, this embodiment also provides following technical measures.(1), the inverting input (negative terminal among the figure) at operational amplifier (A3) connects a delay switch circuit, when leading to the assurance power supply, make main circuit enter a reliable and stable duty, delay switch circuit is made up of switching tube (T2) and differentiating circuit (C8, R13), and the inverting input (negative terminal of A3) of the output termination operational amplifier (A3) of switching tube (T2), electric capacity (C8) connect power supply.(2), between the output terminal of operational amplifier (A3) and speech IC input end, meet a voice signal selector switch K1.Use selector switch and storage multilingual, for example the voice of " no smoking ", " No burning " etc. are integrated, and the multiple function of warning of lovely realization is used for different occasions.(3), connect the signal output part of the input termination operational amplifier (A3) of a switching tube (T5), switching tube (T5) at the ground end (2 end) of audio signal amplifier (LM386), when the A3 no signal is exported, T5 is in cut-off state, note amplifier is not worked, in the time of can making no extraneous signal like this, note amplifier is in off position, to reduce quiescent dissipation.
By Fig. 2, the output terminal of this embodiment main circuit operational amplifier (A3) also connects the optically-controlled signal circuit of warning, when extraneous light is dark, make signal by this circuit of warning, drive pilot lamp and illuminate the board of warning, optically-controlled signal is warned circuit by light sensor (R15), operational amplifier (A4), switching tube (T3) and pilot lamp (L1) are formed, the warn input end (anode of A4 among the figure) of operational amplifier (A4) of circuit of the output termination optically-controlled signal of operational amplifier in the main circuit (A3), light sensor (R15) is attempted by operational amplifier (A4) input end, the output terminal of operational amplifier (A4) connects the input end of switching tube (T3) by resistance (R18), and pilot lamp (L1) is serially connected in the load circuit of T3.When extraneous light was dark, A4 can make pilot lamp bright with signal by R18 driving switch pipe T3.
By Fig. 2, the signal output part of this embodiment main circuit operational amplifier (A3) connects by resistance (R19) opens the signal input part of missing method triode (T4), the output terminal of triode (T4) connects sampling interface (CZ), (CZ) sends signal by interface, is used for outer signals and detects.Fig. 3 provides the embodiment electrical schematic diagram of multichannel control alarm.This multichannel control alarm is by signal input interface (A, B), and voltage comparator (A5), signal amplifier (A6), chimes of doom integrated package (HFC9564), note amplifier (T1) and loudspeaker (SP) are formed.The signal input interface (A, B) of multichannel control alarm connects sampling interface (C2).When input interface detects a human mobile signal or circuit and breaks down, the A terminal voltage will be higher than comparative voltage, voltage comparator (A5) will be exported a signal, this signal is amplified to chimes of doom integrated package (HFC9564) through shaping, behind the note amplifier, loudspeaker send the voice sound of warning, and the operator on duty of announcement notes.
In sum, the utlity model has following advantage and good effect: (1) has sound effect of warning, and the board of warning than simple more can attract much attention; (2) have the optically-controlled signal alarm function, illuminate the board of warning by driving indicator lamp, overcome the board of generally warning does not have the effect of warning in the dark situation of extraneous light defective; (3) set up multichannel control warning device, can be with the sampled signal dispensing such as the warning device that arranges in the night shift room, in case go wrong, the operator on duty finds at once. Because the warn device that the utility model integrates that voice are warned, light-operated indication and signal send multichannel control warning function can play warning effect effectively, is a kind of speech sound alarm device of practicality.
