3 Claims

1. A management method for smart gas safety inspection route based on a Geographic Information System (GIS), wherein the method is executed by a smart gas safety management platform of an Internet of Things system for smart gas safety inspection route based on the GIS, comprising:

determining 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 the determining track information of an inspector according to location data of the inspector includes:

obtaining the satellite positioning information of the inspector based on the inspection device;

in response to the satellite positioning information satisfying a preset signal condition, determining a reference location of the inspector based on the satellite positioning information;

determining 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;

determining a calculated location of the inspector by using the reference location as a reference based on the motion information and the orientation information;

determining 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, obtaining at least one image of the at least one inspection target by a photographing device; and

determining 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,

determining a recommended inspection route based on the track information and gas monitoring data, and prompting the recommended inspection route through a display screen based on a first display parameter, wherein the determining a recommended inspection route based on the track information and gas monitoring data includes:

obtaining 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;

determining an inspection priority of the at least one inspection branching route based on the inspection branching route information and the gas monitoring data;

determining the recommended inspection route based on the inspection priority and the track information;

identifying an inspection phase of the inspector;

in response to the inspection phase being a first phase, obtaining a remote inspection branching route based on at least one precise location of the inspector; and

determining the recommended inspection route according to a preset inspection rule based on an inspection priority of the remote inspection branching route; and

in response to the track information not satisfying the preset requirement,

determining a display condition of the display screen based on a second display parameter.
