Embodiment Construction

[0025] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not constitute a conflict with each other.

[0026] Such as figure 1 As shown, firstly, four LED lighting strips 2, 3, 4 and 5 that emit light uniformly are arranged horizontally on the four walls of the rectangular indoor space 1. The installation height of each LED lighting strip is the same, and two relative installations are kept The lengths of the LED lighting strips are consistent and relatively aligned, and a mobile platform 6 is placed in the area surrounded by the four LED lighting strips.

Abstract

The invention discloses an energy-carried positioning method in a plane environment. The method comprises the following steps: setting up horizontal and vertical LED lighting strips, a mobile platformand a solar energy epoxy panel in a rectangular room; the solar energy epoxy panel detecting the light intensity and the flicker signals from four LED lighting strips; sending part of the signals output from the solar energy epoxy panel directly to a storage module for storage; sending part of the signals output from the solar energy epoxy panel to four band-pass filters that match the flicker frequency of the respective LED lighting strips to extract the harmonic components of the signals output from the solar energy epoxy panel, which match the flicker frequency of the four LED lighting lights, and then transmitting the harmonic components to a positioning controller; and the positioning controller determining the horizontal position and the vertical position of the mobile platform in the indoor space according to the relative relationship between the solar energy epoxy panel and the amplitude of the harmonic components matching the flicker frequency of the LED lighting lights. Thehorizontal and the vertical positions are combined to achieve the planar position sensing, self-positioning and electrical energy storage of the indoor mobile platform in an indoor environment.

Description

technical field [0001] The invention relates to the technical field of planar position positioning, in particular to an energy-carrying positioning method in a planar environment. Background technique [0002] The plane location positioning technology in the indoor environment is the key technology for building autonomous walking and positioning platforms such as automatic walking cars and intelligent service robots, and these platforms are the basis for building smart factories, smart logistics, smart public service facilities and smart home equipment . In the external form of rising labor costs and aging population, it is becoming more and more urgent to develop indoor positioning technology with higher precision, adapt to the general internal environment of buildings, and not rely on special ground signs. Therefore, this technology has important practical significance. [0003] Traditional positioning technologies are mainly divided into GPS systems in open environments...
