Abstract
Disclosed is an apparatus and a control method of an automatic working system, and the control method comprises the following steps: generating a boundary signal by a signal generating apparatus; generating an electromagnetic field as the boundary signal flows by the boundary wire; detecting the electromagnetic field by an automatic moving device to at least generate a first detection signal and a second detection signal, and multiplying the first detection signal and the second detection signal to generate a product signal; determining a first signal point and a second signal point by the product signal; generating characteristic values based on parameters of the first signal point and the second signal point, comparing the characteristic values with preset thresholds, and judging whether the first detection signal is interfered by noise, thereby effectively removing an interference signal. Also disclosed is an automatic working system executing the above control method.
