Claim 1:
2. An Internet of Things system for smart gas safety inspection route based on a Geographic Information System (GIS), wherein the Internet of Things system includes a smart gas safety management platform, and the smart gas safety management platform is configured to:
determine track information of an inspector according to location data of the inspector, wherein the location data is obtained based on an inspection device, the location data including at least one of satellite positioning information, motion information, or orientation information of the inspector, wherein to determine track information of an inspector according to location data of the inspector, the smart gas safety management platform is further configured to:
obtain the satellite positioning information of the inspector based on the inspection device;
in response to the satellite positioning information satisfying a preset signal condition, determine a reference location of the inspector based on the satellite positioning information;
determine the track information of the inspector based on the reference location and a gas pipeline network and station map, wherein the gas pipeline network and station map is obtained based on a gas GIS;
determine a calculated location of the inspector by using the reference location as a reference according to the motion information and the orientation information;
determine at least one inspection target near the calculated location that satisfies a preset location condition based on the gas pipeline network and station map;
in response to a count of the at least one inspection target satisfying a preset count requirement, obtain at least one image of the at least one inspection target by a photographing device; and
determine the track information of the inspector based on the at least one image of the at least one inspection target and the calculated location;

in response to the track information satisfying a preset requirement,
determine a recommended inspection route based on the track information and gas monitoring data, and prompt the recommended inspection route through a display screen based on a first display parameter;
wherein to determine the recommended inspection route based on the track information and gas monitoring data, the smart gas safety management platform is further configured to:
obtain inspection branching route information based on a content of an inspection task, wherein the content of the inspection task includes at least one inspection branching route connected with an inspection main route;
determine an inspection priority of the at least one inspection branching route based on the inspection branching route information and the gas monitoring data;
determine the recommended inspection route based on the inspection priority and the track information;

wherein to determine the recommended inspection route, the smart gas safety management platform is further configured to:
identify an inspection phase of the inspector;
in response to the inspection phase being a first phase, obtain a remote inspection branching route based on at least one precise location of the inspector; and
determine the recommended inspection route according to a preset inspection rule based on an inspection priority of the remote inspection branching route;

in response to the track information not satisfying the preset requirement,
determine a display condition of the display screen based on a second display parameter.
