Problems solved by technology

However, such distribution is relatively sparse, and the staff in the pipe gallery cannot receive 3 or more signal strength values ​​at the same time
And when the traditional position fingerprint method is used for positioning, a large number of offline data points need to be collected, and this method requires a huge labor cost

Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation.

[0029] figure 1 A flowchart for constructing the wireless location fingerprint database of the present invention. The off-line location fingerprint database construction process of the present invention is as follows: in the acquisition stage, firstly carry out the location fingerprint data collection to each point of the target area, then carry out filter processing, construct the collection location fingerprint library; Points, use the adaptive simulated annealing-particle swarm-kriging interpolation algorithm to calculate the interpolation value of each point, that is, the received signal strength value, and construct the interpolation location fingerprint database. Combining the collected location fingerprint database with the interpolated location fingerprint database can jointly constitute the offline location fingerprint database p...

Abstract

The invention discloses an off-line position fingerprint database construction method based on adaptive simulated annealing-particle swarm-Kriging interpolation, and the method comprises the following steps: collecting the received signal intensity values of a part of points, and carrying out the parameter optimization of a theoretical spherical model variation function through an adaptive simulated annealing particle swarm optimization algorithm, and establishing a self-adaptive simulated annealing-particle swarm-Kriging interpolation model. Through the interpolation model, the received signal strength value of the prediction point is estimated, and the received signal strength value and the value of the collection point jointly construct a complete offline position fingerprint database.

Description

technical field [0001] The invention relates to the field of indoor positioning, in particular to an off-line location fingerprint library construction method based on an adaptive simulated annealing-particle swarm-kriging interpolation algorithm. Background technique [0002] The personnel positioning system is an important part of the operation and maintenance management of the urban underground utility corridor. From the perspective of safety, the inspectors of the underground utility corridor not only need to overcome the complicated working conditions caused by the complex environment, but also face a certain degree of danger. In the event of an emergency, the system of the integrated pipe gallery operation and maintenance center needs to calibrate the specific location of the staff member in time for rescue. According to different applications of positioning technology, the positioning system in the construction of domestic comprehensive utility corridors can be divid...
