Abstract

The invention discloses a multi-grade sound-light alarm device which comprises a central control unit, a sound alarm unit and a light alarm unit. The multi-grade sound-light alarm device is characterized in that the central control unit is connected with the sound alarm unit and the light alarm unit separately and further connected with a power supply unit and a communication unit; a buzzer is adopted as the sound alarm unit, a single chip microcomputer is adopted as the central control unit, 24-V power supply is adopted as the power supply unit, a three-color highlighted integrated LED lamp sheet is adopted as the light alarm unit, and the communication unit achieves signal access. According to the multi-grade sound-light alarm device, a common cathode lamp sheet is adopted as the three-color highlighted integrated LED lamp sheet, graded alarming can be conducted according to the set grade, and therefore people can visually know the alarming grade and intensity.

Description

technical field [0001] The invention relates to a multi-stage sound and light alarm device. Background technique [0002] Sound and light alarm devices, as various alarm indicating devices, have a very large market demand in petroleum, chemical, smelting and other industries. With the development in recent years, a wide variety of sound and light alarm products have been developed, but the single alarm method adopted by large institutes is only a method, and there are few products that are classified according to the alarm signal, and a certain number of LED lights are used for the indication of the light alarm. way, which not only increases the production process. At the same time, the intensity of the alarm indication is relatively simple, and most of them can only be one color or flashing pattern. The alarm prompt is relatively weak. [0003] With the continuous improvement of human production level at this stage, the requirements for sound and light alarm devices are ...
