Identification and distance detection for ultrasonic sensor by correlation method
This paper presents a method for identification and distance detection for ultrasonic sensors of indoor mobile robot by using correlation scheme. The transmitted signal is identified by correlation between known model patterns and the patterned signal from transmitters and this scheme is useful when multiple sensors are involved. Distance detection by correlation is shown to be more accurate th...
متن کاملPerformance Analysis of PING))) Ultrasonic Distance Sensor
The concept of a robot refers to a machine or device with the capacity to perform complex actions [MerriamWebster01]. In this current era of technology, robotics serves as more than just a branch of science [Wikipedia02], but a field with opportunity to improve the lives of people around the world. From designing a self-driving wheelchair for those in retirement communities struggling with mobi...
متن کاملZigbee-Based Wireless Distance Measuring Sensor System
A cost effective ZigBee-based wireless parking sensor system is presented in this article. Ultrasonic transmitter and receiver are used for distance measurement. An evaluation, control and wireless data transfer are realized by one chip Panasonic hybrid chip PAN4450 (8-bit microcontroller + IEEE 802.15.4 radio). System consists of four independent distance sensors and one central display and co...

This document presents the principle of ultrasonic distance measurement is described, the main error sources of ultrasonic distance measurement are analyzed also. A method of improving precision of ultrasonic distance measurement in air, in which the transmission speed of ultrasonic wave if corrected by measured air temperature and the forward edge of receive wave can be determined accurately b...
متن کاملLow-Cost Ultrasonic Distance Sensor Arrays with Networked Error Correction
Distance has been one of the basic factors in manufacturing and control fields, and ultrasonic distance sensors have been widely used as a low-cost measuring tool. However, the propagation of ultrasonic waves is greatly affected by environmental factors such as temperature, humidity and atmospheric pressure. In order to solve the problem of inaccurate measurement, which is significant within in...
