Networking control method and automatic flushing system of flushers used in public toilet

The invention relates to a networking control method and an automatic flushing system of flushers used in a public toilet. Each squatting position in the public toilet is provided with one flusher provided with a sensor, a single-chip and an electromagnetic valve. The control method comprises the following steps of: a) connecting the single-chip of each flusher together by using a bus; b) detecting the squatting position by the sensor, from the time when a person is detected at the squatting position to the time when the person leaves the squatting position, recording the residence time of the person at the squatting position; and c) when detecting that the person leaves the squatting position, checking whether other flushers are flushing at that time, if so, waiting, otherwise, flushing.The automatic flushing system adopting the method controls each flusher in a unified mode to avoid water pressure reduction caused by flushing at the same time so as to guarantee public health and save water resources; and si
