Inspection method and inspection system based on multi-sensor intelligent terminal

The invention discloses an inspection method and an inspection system. The inspection system comprises a background management center, and an intelligent mobile terminal, such as an android mobile terminal, supporting NFC (Near Field Communication), a gyroscope, an electronic compass and an accelerometer. The method comprises the steps of prearranging an inspection route and the inspection time by the background management center, and appointing an inspector; automatically generating an inspection task by the background management center, and sending the inspection task to the appointed inspector; when the inspector reaches the fixed starting point, reading the label of the starting point by the intelligent mobile terminal so as to start the inspection; in the inspection process, calculating the displacement distance away from the former known point through an accelerometer and a gyroscope of the intelligent mobile terminal so as to calculate the current position, thus drawing and recording the inspection route; when the inspector reaches the next inspection point, reading the label of the inspection point, correcting the calculating error of the terminal position, and repeating the process until the inspector reaches the last inspection point; additionally remarking the excursion, overtime and point leakage conditions, and marking the finish of the inspection; after the inspector returns to a central control room to access WIFI (Wireless Fidelity) of the central control room, automatically authenticating the identity by the background management center and the mobile terminal and transmitting the inspection records; and carrying out statistical analysis on the inspection records including the inspection route by the background management center so as to assist performance management and decision. According to the inspection method and the inspection system, the intelligent mobile terminal can be used for recording the route of the inspector in real time, and monitoring and alarming the condition that the inspector deviates the inspection route and inspects overtime and the like in real time, the problems that the existing off-line inspection system only can be used for monitoring the inspector through scattered inspection points and cannot master the inspection state in real time can be solved, and meanwhile, the defects that in order to realize the functions, the originally used on-line inspection system is high in cost and cannot be flexibly changed as whole wiring construction is needed can be overcome. Particularly, the inspection method and the inspection system provided by the invention can be applied to outdoor inspection, and also can be applied to indoor inspection, thus effectively overcoming the defect that the inspection system based on GPS (Global Positioning System), GIS (Geographic Information System) and GPRS (General Packet Radio Service) cannot be effectively applied to indoor inspection.
