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

Embodiment 1

[0036] refer to figure 1 The control method of the intelligent acousto-optic alarm device shown, the control method is: the power supply is transmitted to the power supply line in different environments with more than two different voltages or frequencies, and the audible-visual alarm device automatically uses the built-in detection unit. Detect the voltage or frequency of the power supply line, and then automatically start the sound and light alarm to work in different states according to the detected voltage value or frequency value in different ranges. That is, the control method of the intelligent sound and light alarm device is: set two or more different voltages, frequencies or power supply lines of the voltage and frequency, and set a detection unit on the sound and light alarm device, and use the detection unit to detect the sound. The voltage and frequency of the access power line of the light alarm device, or different values ​​of the voltage and frequency values, ac...

Embodiment 2

[0048] refer to Figure 4 The technical features of the intelligent acousto-optic alarm device with various warning modes are as follows: it is realized by electronic circuit, and the detection unit is passed through the rectification and filtering circuit 5, the detection circuit 6, the trigger 34, the time oscillator 35 and the high Composed of a frequency oscillator 36, the voltage threshold or frequency threshold is detected by the detection circuit 6 to trigger the time oscillator and the high frequency oscillator to oscillate. The detection unit is connected with the sound and light warning unit to form a warning device 3 with an integrated structure. The detection unit 4 triggers to change the oscillation time of the time oscillator 35, the output voltage of the high frequency oscillator 36, etc. by detecting different voltage values ​​and frequency values ​​on the power supply line, thereby automatically starting different warning effects of the alarm device. All the ...

Embodiment 3

[0051] The technical characteristics of this embodiment are: the alarm system also includes lighting lamps 8 distributed in various areas of construction operations, the lighting lamps 8 adopt LED lights, and the LED lights are auxiliary alarm equipment for warning equipment, and have an alarm function, namely When the warning device 3 activates the alarm function, the LED lighting lamp 8 also plays a warning role, which can cause flashing warnings in different ways, or even change colors and other effects. All the other are the same as the above embodiment.

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...
