Ultrasound Indoor Positioning System

This paper is designed having introduced that ultrasonic distance measurement technology-based interior of one kind fixer system mainly. Ultrasonic positioning is simple in structure, practical, low cost, the advantages of precise ranging. Therefore, was widely applied to various fields.Ultrasonic technology application current situation the main body of a book has been introduced . Have explained content and significance that the problem studies . Have introduced the ultrasonic sensor characteristic property detailedly. System choice sensor application has provided a rationale. This paper described the general concept of system design. Hardware details of the synchronous wireless signal processing circuit, ultrasonic transceiver circuits, temperature compensation circuitry, etc. Software introduces the indoor positioning algorithms, Main Controller program flow and measuring the point program structure of microcontroller.This article also analyzed the experimental results,introduce that to may produce the error cause having been in progress, As a basis for improving the system accuracy has taken appropriate measures.
