A guide-type virtual wall system. The system comprises a beacon (11, 44) and a robot (12), wherein a transmission module of the beacon (11, 44) directionally transmits a first signal, and a region covered by the first signal is a beacon signal region (13). The robot (12) comprises a beacon signal receiving module corresponding to the beacon signal transmission module. After the robot (12) enters the beacon signal region (13) and the first signal is detected by the beacon signal receiving module, the robot (12) advances towards the direction of the beacon (11, 44), and then crosses over or exits from the beacon signal region (13) until a second signal is detected by the robot (12). The system can restrict the robot (12) from entering a certain region, and the region where a virtual wall is located is not missed, and at the same time, enables the robot (12) to cross over the virtual wall to enter the restricted region when required. |
