Description
Technical field
A kind of water supply instruction system is the utility model is related to, more particularly to a kind of cutting off the water based on force sensing resistance refers to water supply
Show system
Background technology
Force sensing resistance is a kind of pressure-dependent resistance of resistance, also referred to as piezoresistive.So-called piezoresistance effect is
The effect that the resistivity of semi-conducting material changes with the change of mechanical stress.Can be by force sensing resistance according to the characteristics of force sensing resistance
Apply in fields such as torque meter, semiconductor microphone, pressure sensors.At present, whether there is water supply in the water pipe in water supply field
We can only just can know that by opening tap, and such method is time-consuming and waste water resource.
Utility model content
Problem to be solved in the utility model is to provide a kind of cutting off the water and water supply instruction system based on force sensing resistance,
Its cost is low, simple in construction, it is not necessary to opens tap and only needs the indicator lamp for watching instruction system just to can know that in water pipe
Whether water supply is had.
In order to solve problem above, the technical solution of the utility model is as follows：
A kind of cutting off the water and water supply instruction system based on force sensing resistance, its structure includes stage circuit, secondary circuit and water
Pipe；The stage circuit is by a force sensing resistance, a first class of protection resistance, an one-level dc source and an electromagnet string
Connection forms closed circuit；The secondary circuit includes a second class protection resistance, a LED light, a two level direct current
Source and a tongue tube；Tongue tube and LED light in the secondary circuit is in parallel, the second class protection in the secondary circuit
Resistance and two level dc source are connected with the LED light and the tongue tube；Electromagnet and institute in the stage circuit
The tongue tube stated in secondary circuit is adjacently positioned；The force sensing resistance in the stage circuit is located in the pipe of water pipe.
The beneficial effects of the utility model are：Whether resistance that water can change force sensing resistance is had in water pipe, force sensing resistance
The change of resistance can change the change of the current strength in stage circuit, and the change of the current strength in stage circuit can change electricity
The change of the electromagnetic force size of magnet, what the change of the electromagnetic force of electromagnet can control the tongue tube in secondary circuit connects through and off
Open, disconnection and the connection of tongue tube can have influence on whether LED light lights.Therefore whether having water in water pipe, we can directly lead to
Cross whether viewing LED light lights and know.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in figure 1, its structure of the utility model includes stage circuit 1, secondary circuit 2 and water pipe 3；Stage circuit 1 by
One one-level dc source 13 of first class of protection resistance 12, one of force sensing resistance 11, one and the series connection formation of electromagnet 14 are closed
Close circuit；Secondary circuit 2 includes a two level dc source 23 and one of LED light 22, one of second class protection resistance 21, one
Individual tongue tube 24；Tongue tube 24 and LED light 22 in secondary circuit 2 is in parallel, the second class protection resistance 21 in secondary circuit 2
Connected with two level dc source 23 with LED light 22 and tongue tube 24.
In order that the electromagnetic force of electromagnet 14 can have an impact to tongue tube 24, the electromagnet 14 and two in stage circuit 1
Tongue tube 24 in level circuit 2 is adjacently positioned；Offer that through hole makes stage circuit 1 on the tube wall of water pipe 3 is routed through water pipe 3
Pipe and the force sensing resistance 11 in stage circuit 1 is located in the pipe of water pipe 3.
The utility model so works：As shown in figure 1, when having water in water pipe 3, force sensing resistance 11 is under pressure increasing
Big resistance diminishes so that become big by the current strength of electromagnet 14 in stage circuit 1, passes through the current strength of electromagnet 14
Becoming big causes electromagnetic force caused by electromagnet 14 to become big so that neighbouring tongue tube 24 is connected, and tongue tube 24 just makes after connecting
Obtaining the voltage at the both ends of LED light 22 in secondary circuit 2 and reducing causes LED light 22 not light；Do not have when in water pipe 3
During water, the resistance of force sensing resistance 11 becomes big and to diminish and then electric caused by electromagnet 14 by the current strength of electromagnet 14
Magnetic force diminishes, and electromagnetic force caused by electromagnet 14 diminishes and then so that tongue tube 24 disconnects, tongue tube 24 causes two after disconnecting
The voltage rise at the both ends of LED light 22 in level circuit 2 is so that LED light 22 is luminous.According to principles above
Directly just can know whether there is water supply in water pipe 3 by the way that whether LED light 22 is luminous.
