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 an infrared controlled multistage sound-light alarm device. The device comprises a central control unit, a sound alarm unit and a light alarm unit, and is characterized in that the central control unit is connected with the sound alarm unit and the light alarm unit respectively, and further connected with a power supply unit, a communication unit, a wireless communication module and an infrared communication module respectively; the sound alarm unit adopts a buzzer, the central control unit uses a single chip microcontroller, the power supply unit uses a 24-volt power supply, the light alarm unit uses a three-color highlighting integrated LED light sheet, and the communication unit is used for accessing signals. According to the invention, the infrared controlled multistage sound-light alarm device can not only realize self-grading alarms through a wired way, but also receive external alarm information through a wireless way to carry out alarm indication. The three-color highlighting integrated LED light sheet uses a common cathode light sheet which can carry out the grading alarms according to set grades, so that people can intuitively understand the alarm grades and intensities.

Description

technical field [0001] The invention relates to an infrared-controlled 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 lig...
