Description
Technical field
The present invention relates to a kind of water supply instruction system, more particularly to a kind of cutting off the water based on force sensing resistance system is indicated with supplying water
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 torque meter, semiconductor microphone, the field such as pressure sensor.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.
The content of the invention
Problem to be solved by this invention is to provide a kind of cutting off the water and water supply instruction system based on force sensing resistance, its into
This is low, simple in construction, it is not necessary to open tap and only need to watch instruction system indicator lamp just can know that in water pipe whether
There is water supply.
In order to solve problem above, technical scheme 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；Institute
Stage circuit is stated by a force sensing resistance, a first class of protection resistance, an one-level dc source and an electromagnet series connection shape
Into closed circuit；The secondary circuit include a second class protection resistance, a LED light, two grades of dc sources and
One tongue tube；Tongue tube and LED light in the secondary circuit is in parallel, the second class protection resistance in the secondary circuit
Connected with two grades of dc sources with the LED light and the tongue tube；Electromagnet in the stage circuit and described two
Tongue tube in level 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 invention are as follows：Whether there is water to change the resistance of force sensing resistance, the resistance of force sensing resistance in water pipe
Change can change the change of the current strength in the change of the current strength in stage circuit, stage circuit and can change electromagnet
Electromagnetic force size change, the change of the electromagnetic force of electromagnet can control the connecting and disconnecting of the tongue tube in secondary circuit,
The disconnection of tongue tube can have influence on whether LED light lights with connection.Therefore whether having water in water pipe, we can directly pass through
Whether viewing LED light is luminous and knows.
Brief description of the drawings
Fig. 1 is the structure and circuit diagram of the embodiment of the present invention.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples：
As shown in figure 1, its structure of the invention includes stage circuit 1, secondary circuit 2 and water pipe 3；Stage circuit 1 is quick by a power
Resistance 11, a first class of protection resistance 12, an one-level dc source 13 and a series connection of electromagnet 14 form closed circuit；Two
Level circuit 2 includes a second class protection resistance 21, a LED light 22, two grades of dc sources 23 and a tongue tube
24；Tongue tube 24 in secondary circuit 2 and LED light 22 are in parallel, second class protection resistance 21 in secondary circuit 2 and two grades it is straight
Stream power supply 23 is connected with LED light 22 and tongue tube 24.
In order that the electromagnetic force of electromagnet 14 can produce the electromagnet 14 and two in influence, stage circuit 1 to tongue tube 24
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 force sensing resistance 11 in stage circuit 1 is located in the pipe of water pipe 3.
The present invention so works：As shown in figure 1, when having water in water pipe 3, force sensing resistance 11, which is under pressure, increases resistance
Value diminishes so that become big by the current strength of electromagnet 14 in stage circuit 1, becomes big by the current strength of electromagnet 14
So that the electromagnetic force produced by electromagnet 14 becomes big so that neighbouring tongue tube 24 is connected, tongue tube 24 just causes two after connecting
The voltage at the two ends of LED light 22 in level circuit 2, which is reduced, causes LED light 22 not light；When there is no water in water pipe 3
When, the resistance of force sensing resistance 11 becomes big and by the current strength of electromagnet 14 to diminish and then the electromagnetism produced by electromagnet 14
Power diminishes, and the electromagnetic force produced by electromagnet 14 diminishes and then so that tongue tube 24 disconnects, tongue tube 24 causes two grades after disconnecting
The voltage rise at the two ends of LED light 22 in circuit 2 is so that LED light 22 is luminous.Just can be with according to principles above
Directly it just can know whether there is water supply in water pipe 3 by the way that whether LED light 22 is luminous.
