Title: AUTOMATIC MOBILE DEVICE, AUTOMATIC WORK SYSTEM AND CONTROL METHOD THEREOF
Abstract:
Provided are a control method for an automatic work system, an automatic work system performing the control method and an automatic mobile device. It has a flexible signal adjustment capability and an effective method for identifying an effective signal, with strong anti-motor interference, anti-adjacent interference, and anti-environmental interference. The control method comprises: a signal generator device (80) generates a boundary signal (SS); the boundary signal flows through a boundary (50) and generates an electromagnetic field; a detection device (110) on an automatic mobile device (10) detects the electromagnetic field to generate detection signals (ST1, ST1' and ST2'), amplifies the detection signals (ST1, ST1' and ST2') to form a gain signal (SG1), and compares a characteristic point of the gain signal (SG1) with a predetermined condition that the characteristic point is higher than lower thresholds (VL1 and VL1') and lower than upper thresholds (VU1 and VU1'); and according to comparison results, automatically adjusting the gain signal (SG1) so that the characteristic point of the adjusted gain signal (SG1) meets the predetermined condition, and to further process the gain signal (SG1).
