The present disclosure discloses a method for managing liquefied natural gas (LNG) tanking safety based on location matching and an Internet of Things system. The method includes that an intelligent terminal perceives and acquires terminal operation information, generates a request for tanking, and sends the request to a management platform; the management platform obtains vehicle information of an LNG tanker after receiving the request, generates a task plan for tanking and sends the task plan to the LNG tanker and the intelligent terminal respectively; the LNG tanker drives to a location of the terminal according to the task plan, and the management platform performs real-time tracking and monitoring on a driving path of the LNG tanker; the LNG tanker completes a two-way location matching authentication with the intelligent terminal through the management platform after arriving at the location of the terminal and performs tanking for the LNG distributed energy intelligent terminal.
