| titleOfInvention | Cistern water level measurement method and device |
| abstract | The disclosure is directed to cistern water level measurement method and devices.This method comprises: triggering is supplied to the switching signal of electromagnet, the electromagnet is used to control the switch of the tank filler opening electromagnetic valve, and the switching signal is pulse width modulating signal；The duty ratio of the pulse width modulating signal is gradually increased, and detects whether the electromagnetic valve is opened；When the electromagnetic valve is opened, the duty ratio of current pulse length modulated signal is obtained；Current cistern water level is calculated according to the duty ratio of the corresponding relationship and the current pulse length modulated signal of the duty ratio of the pulse width modulating signal pre-established and cistern water level.The technical solution does not need additionally to increase the circuit elements such as sensor, and using the inherent characteristic of circuit element, the detection of cistern water level is realized using software algorithm. |
