Patrol completion degree evaluation and calculation method

Abstract

The invention relates to a patrol completion degree evaluation and calculation method, and belongs to the technical field of real-time monitoring management. The method includes the steps of determining a patrol route by obtaining positioning data of a detected device, setting the effective patrol range according to the positioning data of the detected device, judging whether the positioning coordinates of patrol personnel are within the effective patrol range of the detected device or not by collecting the positioning coordinates of the patrol personnel in real time, conducting distance measurement and calculation when the patrol personnel enters the effective range, recording the shortest distance to serve as effective data for patrol evaluation, and not conducting distance measurement or calculation for the personnel and devices if the patrol personnel does not enter the effective range or moves out of the effective range. A large amount of unnecessary system calculation is avoided so that the system operation expenses can be reduced, and the effect is quite obvious especially for large patrol systems.

Description

technical field [0001] The invention relates to a method for evaluating and calculating the in-place inspection degree, which belongs to the technical field of real-time monitoring and management. Background technique [0002] At present, the equipment inspection work in satellite navigation mode is to use positioning technology (GPS, Beidou satellite navigation system, GLONASS, Galileo satellite navigation system, etc.) One-time distance is used as the evaluation basis for the degree of inspection in place. This calculation method is calculated from the starting position of the inspection route to the end position of the inspection route, and the calculation ends. [0003] The formula used to calculate the exact distance between two points is: [0004] Set point A, the latitude and longitude coordinates are (φ 1 ,λ 1 ), set point B, the latitude and longitude coordinates are (φ 2 ,λ 2 ), Δ is the distance, and the distance is: [0005] cosΔ=A1·A2+B1·B2+C1·C2; [0006...

Problems solved by technology

[0009] However, the calculation of this method is very cumbersome, and the real-time calculation will bring a large amount of calculation to the system. In addition, the inspection route for the inspection personnel to perform an inspection task is long and there are many inspection equipment. If starting from the inspection route to At the end, the distance calculation is carried out throughout the process, and the amount of calculation is very large. In addition, the positions of all inspection equipment and inspection personnel are measured and calculated at the same time during the inspection process. The system overhead is huge, and there are many invalid data for measurement and calculation, which greatly reduces the operating efficiency of the system.

[0010] The patent application with the patent number 200910235673.4 proposes a line inspection management system and method, which can monitor whether the inspection of the staff is in place, and evaluate the status of the inspection of the staff by calculation, but the method also needs from From the beginning to the end of the inspection route, it is also necessary to measure the distance throughout the whole process, and the calculation amount is very large. In addition, the positions of all inspection equipment and inspection personnel are measured and calculated at the same time during the inspection process. There are many invalid data measured and calculated, which reduces the operating efficiency of the system.
