Abstract
The utility model relates to a power supply control device, in particular to a pub noise warning control device, belonging to the field of city management. A contact of a relay is serially connected between a 220V alternating current input end and an output end, a photosensitive resistor, a triode and the relay are connected to form an electronic switch, a base electrode of the triode is connected to a microphone, and an emitter electrode thereof is connected with an LED light emitting diode. The pub noise warning control device is mounted in pubs in location requiring mute and can warn and control noise in time, and if noise exceeds a specialized range, the pub noise warning control device can control to cut off power and then restore power supply after a time.
Description
Technical field
The utility model relates to a kind of control device of power supply, and bar noise caution control device belongs to the city management field when special.
Background technology
Present a lot of locations in the city, in order to guarantee civic work, study and rest environment, all require the intensity of controlling noise, but often these locations are again the bustliniest places, city, be provided with many public places of entertainment, the frequent noise that occurs in bar at night can disturb residents, and is necessary in time to control.But city management in night department is next, can't in time manage, even also impossible general management is checked in overtime work.
Summary of the invention
Disturb residents for fear of noise, technical problem to be solved in the utility model provides a kind of bar noise caution control device, and it is simple in structure, can in time warn and control noise, noise to the bar provides timely prompting in advance, if noise surpasses specialized range, and then outage.
Solving the scheme that technical matters of the present utility model adopts is: the contact of series relay between 220V ac input end and output terminal, be connected to form electronic switch with photoresistance, triode and relay, transistor base inserts microphone, and emitter inserts the LED luminotron.
Relay described in the utility model adopts timing relay, after the setting-up time of bar outage arrives, can power again.Inserted voltage stabilizing diode in the path of relay, when noise figure surpassed setting, voltage stabilizing diode was breakdown, and relay is just started working.The LED luminotron is the lamp group that connects more than two, and noise is big more, and voltage is high more, and the LED light emitting diode of lighting is many more.
At first bar～220V alternating current is inserted the input end of bar noise caution control box, pick out by output terminal then, can use.Having under the situation of light daytime, because photoresistance CCD resistance value is little, and transistor base brownout and not conducting, bar noise caution control box is not worked.The night screen has hung down, and under unglazed situation, it is big that photoresistance CCD resistance value becomes, and transistor base voltage enters operating voltage, is in magnifying state.Noise changes noise signal into through microphone, after triode amplifies, lights the noise pilot lamp of LED luminotron.Can see the noise power in the bar intuitively, if surpass setting, transistor emitter voltage increases, and makes voltage stabilizing diode breakdown, the timing relay energising, normally closed contact is opened, the bar outage, after delay time arrives, timing relay reinstatement attitude, the bar powers again.
The beneficial effects of the utility model are: utilize photoelectric effect and electromagnetic induction principle, can effectively control the bar noise.Simple, intuitive, easy to use.
Description of drawings
Fig. 1 is the utility model profile synoptic diagram;
Fig. 2 is the utility model circuit diagram.
Each label is represented successively in Fig. 1～2: 1. control box, 2.220V ac input end, 3.220V ac output end, 4.LED luminotron, 5. rectifier transformer, 6. microphone.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing 1～2 and embodiment.
At first bar 220V alternating current is inserted the 220V ac input end 2 of bar noise caution control box 1, pick out by 220V ac output end 3 then, can use.Having under the situation of light daytime, because photoresistance CCD resistance value is little, and the transistor base brownout, not conducting of VT, bar noise caution control box 1 is not worked.When the evening draws on, under unglazed situation, it is big that photoresistance CCD resistance value becomes, and transistor base voltage enters operating voltage, and VT is in magnifying state.Noise changes noise signal into through microphone 6, after triode VT amplifies, lights the LED luminotron 4 noise pilot lamp in the control box 1, and noise is big more, and voltage is high more, and the LED luminotron of lighting 4 is many more, thereby can see the noise power in the bar intuitively.If noise surpasses setting, triode VT emitter voltage increases, and makes that voltage stabilizing diode D is breakdown, timing relay J energising, and normally closed contact is opened, the bar outage, after delay time arrives, timing relay reinstatement attitude, the bar powers again.Like this, effectively controlled the bar noise.
Claims (3)
1. a bar noise is warned control device, it is characterized in that: the contact of series relay between 220V ac input end and output terminal, be connected to form electronic switch with photoresistance, triode and relay, transistor base inserts microphone, and emitter inserts the LED luminotron.
