Abstract
The utility model relates to a water level control and alarm device, which comprises an alarm portion and a control portion. Wherein the alarm portion comprises a loudspeaker, a crystal triode and a light-emitting diode (LED); the control portion comprises a crystal triode, a LED and a relay. When water level is at middle region, the high level causes the triode on the relay end to conduct, the coil end in the relay is energized, its switch end conducts, the work indicator lamp conducts and lights up, the alarm indicator lamp and the buzzer are unoperated; on the contrary, the triode of the alarm circuit conducts, and the indicator lamp and the buzzer operates. To sum up, The circuit of the utility model achieves the advantages of wide use, simple making, low cost, safety and reliability.
Description
Technical field
The utility model relates to a kind of warning system, is specifically related to a kind of water level control warning circuit.
Background technology
At present, a kind of warning system of prior art, constitute by detector, signal hop and alarm controller, by detector invasion information is become electronic signal and outwards transmission, by wireless transmission detector and wireless launcher are joined, in case the generation alert will send radio signal in the air.Wireless receiver receives that signal produces warning, notifies personnel to handle.The invasion information electronic signal that alarm controller can send intrusion detector becomes the sound and light alarm signal and is shown and write down, store.Its shortcoming is that system constitutes complexity, and wireless receiving may be by more powerful radiowave, and disturb in stray electrical places such as thunder and lightning.
The utility model content
The purpose of this utility model provides a kind of water level control warning system, and it can send warning under the too high or too low situation of water level, can prevent that water storage box is anhydrous, the situation of full water.
The purpose of the utility model water level control warning system is achieved through the following technical solutions: a kind of water level control warning system, comprise the warning part, and described warning partly comprises hummer, transistor, light emitting diode.Be characterized in: also comprise a control section.Described control section comprises transistor, light emitting diode, relay.The signal output part of control section is connected with the signal input part of the part of reporting to the police.
Above-mentioned water level control warning circuit, wherein, described light emitting diode of reporting to the police part is the relay indicating light of water pump, is yellow.
Above-mentioned water level control warning circuit, wherein, described control section comprises transistor, light emitting diode, relay.
Above-mentioned water level control warning circuit, wherein, the light emitting diode of described control section is an alarm lamp, is green.
The utility model water level control warning system makes it to compare with other prior aries owing to adopted above-mentioned technical scheme, has following advantage and positive benefit:
1, the utility model water level control warning system can play amplification owing to be provided with transistor, and making output current compare input current has bigger amplification.
2, the utility model water level control warning system is owing to be provided with light emitting diode, the duty of display element intuitively.
3, the utility model water level control warning system can make controlled output circuit conducting or disconnection owing to be provided with relay, advantage such as have that action is fast, working stability, long service life, volume are little.
Description of drawings
Fig. 1 is the circuit diagram of the warning device part of water level control warning system.
Fig. 2 is the circuit diagram of the control device part of water level control warning system.
Embodiment
See also shown in the accompanying drawing, a kind of water level control warning system, its part of reporting to the police comprises hummer 11, transistor 13, light emitting diode 12.See also shown in the accompanying drawing 2, the control section of water level control warning system comprises transistor 21, light emitting diode 22, relay 23.
The principle of work of this water level control warning system is by the transistor amplifying signal, by loudspeaker electric energy to be converted to acoustic energy.When C is 1 (water is in middle zone), high level makes the triode conducting of relay end, and the coil-end in the relay is subjected to electricity, its switch terminals (the controlled end of forceful electric power) conducting, and relay indicating light also conducting is luminous.At this moment, because of D is 0, the triode of warning circuit ends, and does not have electric current, and alarm lamp and hummer are not worked.Otherwise the relay switch end disconnects, the heavy current installation outage, and relay indicating light does not work, and the triode conducting of warning circuit, pilot lamp and hummer work.
In sum, the utility model can prevent effectively that water level is too high and excessively low, sends then alarm, and is of many uses, makes simply, with low cost, has safe and reliable advantage.
