Abstract

The utility model discloses an acousto-optic alarm signboard. The signboard employs a hollow sandwich structure, wherein a pyroelectric infrared alarm circuit, an LED lamp and a loudspeaker are arranged in an interlayer of the signboard, and the LED lamp and the loudspeaker are connected with the pyroelectric infrared alarm circuit. When the pyroelectric infrared alarm circuit senses that a human body enters a sensing area, the LED lamp is controlled to emit light alarm signals, while the loudspeaker is controlled to emit sound alarm signals. The signboard with an acousto-optic alarm device is arranged in a danger area of a transformer substation, so that the signboard is more eye-catching, and when a working staff enters the danger area for mistake, a pyroelectric infrared sensor is used to monitor human-body signals and a driver is used to drive the loudspeaker and the LED lamp to emit acousto-optic alarm signals, thereby timely warning the working staff to pay attention to safety, and avoiding hazards.

Description

The sound and light alarm Sign Board
Technical field
The utility model relates to the telltale with electricity transmission, is specifically related to a kind of sound and light alarm Sign Board.
Background technology
In existing transformer station, different electric pressure equipment all are equipped with corresponding Sign Board, to prevent operations staff and maintainer's mistakenly entering charged chamber.But existing Sign Board is fairly simple, need initiatively to go the identification marking board to prevent dangerous the generation by the staff, particularly the charged service work place of neighbouring device may not stepped on charging equipment and framework if the staff sees Sign Board clearly by mistake, thereby have an accident.Therefore need to improve existing nameplate, get rid of potential safety hazard.
The utility model content
The utility model provides a kind of sound and light alarm Sign Board, and the staff who enters the forbidden zone is carried out sending the sound and light alarm signal behind the initiative recognition, reminds the staff in time to withdraw from, thereby reduces the probability of casualties and device damage.
Described Sign Board adopts the hollow interlayer structure, is provided with the rpyroelectric infrared warning circuit in described interlayer inside, and the LED lamp and the loudspeaker that are connected with described rpyroelectric infrared warning circuit; Described rpyroelectric infrared warning circuit senses human body and enters after the sensing region, controls described LED lamp and sends caution light; Control simultaneously the described loudspeaker alerting signal of sounding.
Concrete, described rpyroelectric infrared warning circuit comprises Fresnel Lenses, pyroelectric infrared sensor, filtering and amplifying circuit, voltage comparator and the driver that connects successively, wherein said voltage comparator also is connected with reference voltage; Described driver also is connected with switch.
Described rpyroelectric infrared warning circuit sensing range is hazardous location in the transformer station.
Also has the writing that adopts reflective powder spraying on the described Sign Board.
Described LED lamp is installed on around the described Sign Board, adopts the horse race lamp mode to move.Described LED lamp is green when non-alarm condition; Described LED lamp is for red when sending the light warning signal.
Described switch has manual and automatic transmission; When described switch was positioned at manual gear, the described LED lamp of described driver drives and described loudspeaker sent the sound and light alarm signal; When described switch was positioned at automatic catch, according to described pyroelectric infrared sensor sensing human body signal, the described LED lamp of described driver drives and described loudspeaker sent the sound and light alarm signal.
Be provided with the Sign Board of acoustic-optic alarm in the hazardous location of transformer station, not only more eye-catching, and after the staff is strayed into the hazardous location, monitor human body signal by pyroelectric infrared sensor, send the sound flash alarm system signal by driver drives loudspeaker and LED, in time remind the staff to take care, avoid having an accident.
Description of drawings
The structural representation of the sound and light alarm Sign Board that Fig. 1 provides for the utility model embodiment;
