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.
