Abstract
The invention provides an acousto-optic electronic warning board. The acousto-optic electronic warning board comprises a warning board in which a warning is written, and is characterized in that: a microwave induction module, a switching circuit and an alarm module are arranged on the warning board, wherein the microwave induction module comprises a battery BT, a microwave sensor H and a switch K; the microwave sensor H is connected with the battery BT through the switch K; and the output end of the microwave sensor H is connected with the alarm module through the switching circuit. The acousto-optic alarm function is added on the basis of the conventional warning, so the acousto-optic electronic warning board has complete functions and ideal warning effect, reduces the condition that the warning is neglected, particularly reduces the condition that the warning is neglected at night or in case of weak light, and has high work performance.
Description
Technical field
The invention provides a kind of acousto-optic electronic caution board, belong 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.
Summary of the invention
The purpose of this invention is to provide 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 present invention compared with prior art on the basis of existing poster caution, has 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.
