Specific embodiment
It is powered by the external 24V DC power supply of 24V DC supply input J2 to controller, 24V DC power supply passes through steady
Pressure chip 7805 exports stable direct current 5V power supply, and direct current 5V power supply exports stable 3.3V further through voltage stabilizing chip 1117-33
Power supply, pin type sensor are fixed on above tank lid, and pass through tank lid and plastic rod, plastic rod lower section and foam
Block is linked together, and foam block passes through the plastic rod vacantly lower section in water tank and produces when the water level in water tank is lower to foam block
Raw buoyancy is smaller, acts on the pressure on pin type sensor with regard to small by plastic rod, 2 foot of pin type sensor and 3 feet
The voltage difference of output is just smaller, and the numerical value exported by modulus conversion chip is with regard to small, singlechip chip STM32F030F4P6 detection
When smaller to numerical value, it is low level that single-chip microcontroller, which controls 10 feet by high level jump, and 2 feet of optocoupler 2701 also switch to low level, by
The conducting of this optocoupler 2701,3 feet of optocoupler 2701 are identical as the voltage of 4 feet (ignoring 2701 inside tube voltage drop of optocoupler), triode Q1
1 foot also switch to high level, triode Q1 conducting, 1 foot of relay RELAY switchs to low level, and then relay RELAY inhales
It closes, 3 feet of relay RELAY and the conducting of 4 feet, the 220V AC power source accessed by 220V ac power input end J2, water pump
Work is started power up, is injected water into water tank by water pipe, the water level in water tank starts to increase, and the water level in water tank changes
When, the buoyancy that foam block generates also changes, and the pressure acted on pin type sensor is not also identical, pin type sensor
2 feet and the voltage difference of 3 feet output also change, so system can measure the water level conditions in water tank in real time, work as water
When water level in case is higher, the voltage difference of 2 foot of pin type sensor and the output of 3 feet is exported with regard to larger by modulus conversion chip
Numerical value with regard to big, when singlechip chip STM32F030F4P6 detects that numerical value is larger, single-chip microcontroller control 36 pins jumped by low level
Become high level, 2 feet of optocoupler 2701 also switch to high level, and then optocoupler 2701 does not work, and 3 feet of optocoupler 2701 switch to low electricity
Flat, 1 foot of triode Q1 also switchs to low level, triode Q1 cut-off, and 1 foot of relay RELAY switchs to high level, relay
RELAY is disconnected, and Pump Failure stops working.
