Problems solved by technology

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
Alarm reminder is relatively weak

Abstract

The invention discloses a wireless sending multistage sound-light alarm device which comprises a central control unit, a sound alarm unit and a light alarm unit. The device is characterized in that the central control unit is connected with the sound alarm unit and the light alarm unit, and the central control unit is further connected with a power supply unit, a communication unit and a wireless sending module; a buzzer is adopted in the sound alarm unit, a single-chip microcomputer is adopted in the central control unit, 24V power supply is adopted for the power supply unit, a three-color highlight integrated LED lamp sheet is adopted in the light alarm unit, and the communication unit serves as signal access. Radio waves of 433 MHz are adopted for the wireless sending module. Received alarm information is subjected to secondary transmission in a wireless mode. A common cathode lamp sheet is adopted in the three-color highlight integrated LED lamp sheet, and grading alarm can be carried out according to the fixed grade. Therefore, people can visually know the alarm grade and strength.

Description

technical field [0001] The invention relates to a wireless sending 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, there are many kinds of acousto-optic alarm products, 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...
