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, and more particularly relates to a technology for determining the position of a target during movement. Background technique [0002] It is necessary to protect important objects (objects or persons) safely, such as valuables such as wallets and handbags, and important persons such as children and the elderly. Especially for white-collar workers living in big cities and high-end business people, because of the pressure of work and life, their attention is often occupied by other affairs, and they may lose their vigilance to the caretaker around them. It is hoped that a processing center can help and ensure the safety of important objects carried or cared for. The purpose is to immediately detect important objects when they exceed the safe distance, trigger an alarm to track the movement of the objects, and realize the re-acquisition of the objects. [0003] At present, there are two main cat...
