Self-propelled device and work system thereof

A work system of a self-propelled device, comprising:

• a self-propelled device that autonomously travels and performs a work task;
• a base station that acquires satellite observation data, generates differential data according to analysis of the satellite observation data, and transmits the differential data to the self-propelled device;
• and
• an external device comprising a scanning device;
• a communication device;
• and a controller, electrically connected to the scanning device and the communication device, configured to scan a scanned part through the scanning device to acquire an identity code of the scanned part and transmit the identity code to the self-propelled device through the communication device.
