Intelligent acousto-optic alarm device, and control method and alarm system thereof

Abstract

The invention discloses an intelligent acousto-optic alarm device, and a control method and alarm system thereof. The control method is characterized in that a power supply sends different voltages or frequencies to a power supply line in different environments, the acousto-optic alarm device uses a built-in detection unit to detect the voltage or frequency of the power supply line automatically, and according to the ranges of the detected voltage or frequency values, the alarm device is started automatically and works in different states. According to the invention, an alarming function can be started rapidly, delay in evacuation caused by delay or lag of alarm is prevented, the alarming effect of the alarm device is greatly improved, the alarm device can play a better role, and thus, accidents are reduced.

Description

technical field [0001] The present invention relates to a control method and equipment of an alarm device applied in fields such as construction work sites, factories, schools, residences, office buildings or public places, and in particular relates to an intelligent alarm system with sound and light alarms using multiple alarm modes. type alarm device. technical background [0002] There are many people in construction sites, factories, schools, residences, office buildings or public places, and the area distribution is often very large. There are many separations between different areas, and communication between them is almost impossible. When an accident occurs, it is difficult to find it in the first place and choose the correct way to respond in time to inform them to evacuate. For example, in the construction site, the construction environment often has various potential dangers, especially the construction of ships, bridges, tunnels, hydropower stations, and large u...

AI Technical Summary

Problems solved by technology

The traditional sound and light alarm is usually a simple mode of manual activation, unless it is for a special detection alarm such as smoke detection, it cannot predict or detect emergency events in real time, and needs to be activated after the area personnel find an emergency event Alarm alarm, which often takes a certain amount of time

[0005] (2) Light and sound alarm modes are fixed and uncontrollable

In the normal state, when the alarm is activated, the sudden sound of the alarm and the flashing light on the site will frighten and cause panic in the people in the area, which will increase the danger of the personnel. , on-site personnel cannot distinguish the degree of danger of the emergency

[0006] (3) Traditional sound and light alarms use high-voltage halogen lamps or ordinary light bulbs as optical signals. Under harsh working environments, internal components are prone to aging and damage, and the drive circuit is prone to failure.

In addition, halogen lamps and ordinary light bulbs are not efficient and emit a lot of heat

[0007] (4) The traditional sound and light alarm lacks intelligent control technology, and it is very difficult to realize the loudness and frequency control of the sound or the frequency control of the light flash
