Localisation of Inspection Probes in A Storage Tank

Abstract

Indoor Positioning System (IPS) has been widely used in today’s industry for the various purposes of locating people or objects such as inspection, navigation, and security. Many research works have been done to develop the system by using wireless technology such as Bluetooth and Wi-Fi. The techniques that can give some better performances in terms of accuracy have been investigated and developed. In this paper, ZigBee IEEE 802.15.4 wireless communication protocols are used to implement an indoor localization application system. The research is focusing more on analyzing the behaviour of Received Signal Strength Indicator (RSSI) reading under several conditions and locations by applying the Trilateration algorithm for localizing. The conditions are increasing the number of transmitters, experimented in the non-wireless connection room and wireless connection room by comparing the variation of RSSI values. Analysis of the result shows that the accuracy of the system was improved as the number of transmitters was increased.

Fast 50 Hz Updated Static Infrared Positioning System Based on Triangulation Method

“…A variety of wireless techniques are used for different purposes [ 10 ]. For instance, Bluetooth technology is used for locating people in office spaces [ 11 ], while Wi-Fi technology combined with received signal strength index (RSSI) analysis is used for locating pedestrians [ 12 ] or static storage tanks [ 13 ]. UWB technology, with some computational simplifications, can be used to calculate the location of robots on the production hall [ 14 ].…”
