The utility model can be taken along, is safe and reliable, can alter the phonetic content of a warning board at any moment, is free from the restriction by language kinds, is suitable for safe warning effect in various transformer substations and an oil depot, a gas station, a fireproof depot, a theft protection depot.
Description
The utility model relates to a kind of safety alarm device that is used for transformer station, is a kind of automatic speech warning safe board specifically.
At present, power department is in order to solve the safety problem that the mistakenly entering into charged zone causes personal injury accidents, and the existing practice is to make a small-sized word board, near static being hung on the caution district.If someone mistake is bumped or the safety board will be changed direction when meeting wind, lose warning function, mistake was bumped charging equipment after the personnel that cause on the contrary entered charging zone, caused the generation of human casualty accident.With respect to strategic point such as refuelling station, oil depot, fire prevention, antitheft warehouse also need use that the warning safe board is provided, and equally also above-mentioned situation can occur.Existing thus warning safe board is warned in use that reliability also requires further improvement and is perfect.
The purpose of this utility model provides a kind of warning safe board that has warning function, can send voice suggestion in certain distance, thereby has effectively avoided personnel casualty accidents generation, the personal safety of assurance.
For achieving the above object, technical solution of the present utility model is finished by following measure: a kind of automatic speech warning safe board, comprise and adopt detection head, signal indication, photoelectricity isolation, logic, switch, speech memory, note amplifier, loudspeaker are formed, it connects positive-negative power by detecting head, connects integrated circuit (IC) by signal output part
