Abstract
The utility model discloses a kind of novel water level detector, a kind of novel water level detector can not only realize the detection function to water level, simultaneously the water level signal detected can be exported, and add water level it is too low when light indicating circuit and too high water level when audible alarm circuit.The utility model has the advantage of：When water level is too low, light emitting diode extinguishes, and prompts user's water level too low, and when water level is too high, buzzer rings, and prompting user's water level is too high, and such user can just be controlled water level well, will not cause water shortage, will not also cause the waste of water resource；Water level detecting signal can be exported simultaneously, if other control system is also required to gather water level information, it is only necessary to detect the low and high level signal of specified location pin with regard to current water level information can be judged.
Description
Technical field
A kind of novel water level detector is the utility model is related to, especially sound and light alarm can be realized according to the height of water level
The level switch of function.
Background technology
The level switch circuit structure of commercial type is complicated at present, while in use, can not timely by
On the one hand the too high or too low information transmission of water level may cause water shortage phenomenon, on the other hand be likely to result in water money to user
The waste in source, while function is single, can not be added to other control systems.
The content of the invention
The purpose of this utility model is to provide a kind of new level switch, can not only realize the detection to water level
Function, while sound light alarming circuit is added, sound and light of alarm can be realized according to the height of water level, overcome existing water level
Detector because remind user not in time and caused by the waste problem of water shortage problem or water resource.
The technical solution of the utility model is：A kind of novel water level detector, the detector pass through triode and optocoupler
Combination realized to the detection function of water level, at the same add water level it is too low when light indicating circuit and too high water level when sound
Warning circuit.

Water shortage is caused, will not also cause the waste of water resource；Water level detecting signal can be exported simultaneously, if other control system
When needing to gather water level information, it is only necessary to detect the low and high level signal of specified location with regard to current water level information can be judged.
Brief description of the drawings
Fig. 1 is the circuit diagram of novel water level detector.
Embodiment
First place three water level points a, b and c, common port TC, TC and c a point is contour, when water level is less than c points, c and
TC is not turned on, and triode Q3 base stages are low level, therefore triode Q3 ends, and light emitting diode D does not work, and optocoupler M3 does not work,
Q6 ends, and low water level detection output point OUT3 is still high level, and similarly, triode Q1, Q2, Q4 and Q5 cut-off, buzzer S is not
Ring, middle water level detecting output point OUT2 and high water level detection output point OUT1 is still high level；When water level reaches c points, c and TC
Conducting, triode Q3 base stages are high level, therefore triode Q3 is turned on, and light emitting diode D is lighted, optocoupler M3 work, Q6 conductings,
Low water level detection output point OUT3 is low level；When water level reaches b points, b turns on TC, and triode Q2 base stages are high level,
Therefore triode Q2 conductings, optocoupler M2 work, Q5 conductings, middle water level detecting output point OUT2 is low level；When water level reaches a points
When, a is turned on TC, and triode Q1 base stages are high level, therefore triode Q1 is turned on, and buzzer S rings, and optocoupler M1 work, Q4 is led
Logical, high water level detection output point OUT1 is low level.
When other control system need gather water level information when, it is only necessary to judge water level detecting output point OUT1, OUT2 and
OUT3 low and high level, the Position Approximate of water level can be judged, if high water level detection output point OUT1 is low level, explanation
Water level is greater than or equal to a points, if middle water level detecting output point OUT2 puts down for low spot, and high water level detection output point OUT1 is high electricity
It is flat, illustrate water level between a points and b points, by that analogy.
