The anti-theft lock for a watercraft according to claim 6, wherein the power supply circuit (205) provides power to the wireless communication circuit (202), the sensing circuit (203), the motor (204) driving circuit (201) via an external power supply or battery; the sensing circuit (203) and the motor (204) are both connected with the wireless communication circuit (202); the wireless communication circuit (202) comprises a GPRS circuit, a SIM card circuit, a debugging interface circuit and a watchdog circuit, wherein the SIM card circuit, the debugging interface circuit and the watchdog circuit are all connected with the GPRS circuit, the GPRS circuit is in wireless communication connection with the information management circuit (300), and the lock can be opened only after the position of the monitoring logistics is remotely authorized.
8. The anti-theft lock for a watercraft according to claim 7, wherein the information management circuit (300) comprises at least a transceiver circuit in communication with the GPRS circuit; the device at least comprises a memory for storing preset unlocking positions and unlocking time information; the calculation circuit compares the received unlocking position information and time information of the request with preset unlocking positions and unlocking times.
