The utility model provides a kind of acousto-optic electronic caution board, belongs to electric system warning sign technical field.

Background technology

Existing warning sign mostly is a plate with the caution poster, function singleness, and the caution effect is also undesirable, can not play warning function effectively.

The utility model content

The purpose of this utility model provides and a kind ofly can overcome above-mentioned defective, rational in infrastructure, multiple functional, caution acousto-optic electronic caution board satisfactory for result.Its technical scheme is:

Comprise with the warning sign of caution poster, it is characterized in that: microwave induced module, on-off circuit and alarm module are installed on warning sign, wherein microwave induced module comprises battery BT, microwave remote sensor H and K switch, wherein microwave remote sensor H meets battery BT through K switch, and output terminal is through on-off circuit module taking alarm.

Described acousto-optic electronic caution board, on-off circuit comprises triode Q and relay J, wherein the base stage of triode Q connects the output terminal of microwave remote sensor H, grounded emitter, collector meets battery BT through relay J and K switch successively, the moving contact 2 of relay J meets battery BT through K switch, and normally closed contact 1 sky connects, the input end of normally opened contact 3 modules taking alarm.

Described acousto-optic electronic caution board, alarm module comprises resistance R 1-3, capacitor C 1-3,555 timer U1, voice module U2, loudspeaker L and speedlight VD, the 1 pin ground connection of 555 timer U1 wherein, after 2 pin and 6 pin join respectively through capacitor C 1 ground connection, succeed the normally opened contact 3 of electrical equipment J through the bleeder circuit of resistance R 1-2 formation, the junction of resistance R 1-2 connects 7 pin of 555 timer U1,4 pin of 555 timer U1, after joining, 8 pin succeed the normally opened contact 3 of electrical equipment J respectively, connect the trigger end of voice module U2 through capacitor C 3,3 pin of 555 timer U1 meet speedlight VD, 15 foot meridian capacitor C2 ground connection, 1 pin of voice module U2 meets battery BT through K switch, 3 pin ground connection, 4 pin and 5 pin meet loudspeaker L.

Its principle of work is: this acousto-optic electronic caution board hangs on the high voltage equipment, when the people is close, it is movable in reconnaissance range that microwave induced module has detected the people, can make the on-off circuit closure by the output high level, the warning of sounding that is triggered of audio alert module, the luminous warning of luminous alarm module work simultaneously stops sound and light alarm after a while.

The utility model compared with prior art on the basis of existing poster caution, has been set up sound, light is reported to the police, and is multiple functional, warns satisfactory for resultly, has reduced unheeded situation, unheeded situation when particularly having reduced night or light difference.
