Embodiment

[0095] First, the present invention describes the simulation parameters, uses Matlab to carry out simulation verification, and the compressed sensing reconstruction algorithm is the BP algorithm. The model positioning area is set as a square area of ​​50m×50m, divided into 196 grids of 14×14. The value of the sensor number M is 49, and the maximum number of iterations is 6. Signal strength-distance model parameters: P 0 =-40dBm, n p = 2,D 0 =1.

[0096] The target is at the center of the grid:

[0097] Place the target at the center of the grid at different positions, and use the compressed sensing positioning algorithm to calculate the maximum x of the reconstructed X under different signal-to-noise ratios n The grid value corresponding to the component, that is, the specific position of the target. Figure 4 The positioning results of the system under three conditions of no noise, SNR=5dB and SNR=20dB are given with the number of targets being 15. It can be seen from ...

Abstract

A compressive sensing-based power grid equipment patrol inspection positioning method is disclosed. A positioning method applied to power grid equipment patrol inspection is provided via combination of compressive sensing and a method of joint alternate iteration of multiple objects. Coarse positioning is realized via a compressive sensing algorithm; as for a condition that the objects are not positioned at a network center, fine positioning is conducted via the method of joint alternate iteration of multiple objects and a diamond search method. Compared with a traditional compressive sensing and positioning algorithm, the compressive sensing-based power grid equipment patrol inspection positioning method is advantageous in that positioning accuracy is improved, equipment can be positioned rapidly, tour inspection workers can be monitored in real time, work quality of the tour inspection workers is improved, and management efficiency is enhanced; great significance for power grid equipment patrol inspection intelligentization, power grid daily operation and maintenance and management efficiency improvement and power grid automatic operation and maintenance and management improvement is realized.

Description

technical field [0001] The invention relates to the technical field of power grid patrol inspection, in particular to a power grid patrol inspection and positioning method. Background technique [0002] With the continuous development of power grid technology and the continuous deepening of power grid transformation, the scientific, economical and efficient operation of the power grid has put forward higher requirements for the level of automatic operation and maintenance management of the power grid. The power grid must further strengthen the refined management of daily operations of enterprises and improve the efficiency of daily operation and maintenance management. The inspection of power grid equipment is one of the important contents of power grid operation and maintenance management. The wireless monitoring technology of equipment and the monitoring technology of inspection personnel in place are put on the agenda. [0003] Traditional power grid equipment inspection...
