Wireless communication system and method for determining position of target object

Abstract

The invention relates to wireless communication technologies for target position measurement in the moving process, and provides a wireless communication system and method for determining the position of a target object. The problems that the target object is low in accuracy of the missing prevention function, low in speed, poor in safety, high in cost and the like are solved. The wireless communication system comprises a main machine and a secondary machine, wherein the main machine comprises a Bluetooth module, a processor module, a mobile sensor, an alarm apparatus and a positioning display, and the secondary machine comprises a Bluetooth module. The wireless communication method comprises the steps that the coordinates of three track points of the main machine are obtained through sensor signal calculation; the distance between each track point and the secondary machine is obtained through a Bluetooth RSSI technology, a security alarm prompt is given out when the distance between each track point and the secondary machine exceeds the security distance, target tracking is started, and the coordinates of the secondary machine are calculated. If the secondary machine moves, the sampling rate of the track points of the main machine is increased, and KALMAN filtering is used for correcting the sampling result so as to improve positioning accuracy. The wireless communication system and method for determining the position of the target object are high in security, short in positioning time, high in object searching speed and positioning accuracy, easy to implement and large in market size.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to the technology used by wireless communication technology to measure the position of a target in the process of moving. Background technique [0002] It is necessary to protect important targets (items, or people) safely, such as wallets, handbags and other valuables, children, the elderly and other important people. Especially for white-collar workers living in metropolises and high-end business people, due to the pressure of work and life, their attention is often occupied by other affairs, and they may lose their vigilance to the things around them. It is hoped that there is a processing center that can help and ensure the safety of the important targets that are carried or guarded. The purpose is to immediately detect and trigger an alarm to track the movement of the target when the important target exceeds the safe distance, so as to realize the reacquisition of th...
