Specification

Description:FIELD OF THE INVENTION
This invention relates to zigbee-enabled low-power localization system for seamless indoor-outdoor positioning methods.
BACKGROUND OF THE INVENTION
Long-term operation and exceptional accuracy are guaranteed by this energy-saving design, which makes it perfect for a variety of applications requiring reliable and efficient localization capabilities. This development presents a sophisticated localization system designed to easily track and locate items or people traveling between interior and outdoor environments by utilizing a combination of wireless connectivity, motion detection, and GPS technology.
The main problem this invention attempts to solve is the need for a localization system that can easily follow and accurately determine the location of things or people when they move from interior to outdoor spaces. Existing systems often struggle to provide reliable and consistent location data in these many contexts, which leads to inefficiencies in applications used for asset tracking, navigation, and monitoring.
US9482739B2: An apparatus and method is provided for indoor/outdoor transition detection of devices to improve selection of the navigation algorithms. To determine whether an outdoor-to-indoor transition has occurred, a mobile device can determine whether a difference between an indoor position determined using indoor position information and outdoor position determined using outdoor position information is less than a threshold and can conclude that the mobile device transitioned from outdoor to indoor of the structure, if the difference is less than the threshold. Also, to determine whether an indoor-to-outdoor transition has occurred, the mobile device can determine whether an indoor position survey area exists, determine whether an outdoor position determined based on outdoor position information is outside of the survey area, and determine whether a signal strength associated with the outdoor position location information is greater than a threshold.

The coordinated actions of specialized nodes outfitted with a variety of sensors and communication modules enable this innovation to function. The system combines motion sensing, GPS positioning, and intelligent ZigBee technology to provide seamless indoor-outdoor localization while consuming the least amount of electricity. This ensures accurate and consistent location in a variety of settings while maintaining energy efficiency, making it appropriate for a broad range of uses, from navigating complex indoor spaces to tracking and monitoring outside assets. The invention uses a carefully thought-out series of steps to achieve precise positioning indoors and outdoors while consuming the least amount of energy. The two specialized nodes at its core, ZELPT_PSNode and ZELPR_PSNode, are each equipped with customized parts made for their respective functions.
First, let's examine ZELPT_PSNode's functioning. An STM32 Processor Board is used by this node to manage the different operations of the system. It uses a GPS module to collect external positional data and a ZigBee module for wireless communication within the network. Additionally, a Bluetooth module uses BLE finding modules to assist in determining initial placement. When a Motion Sensor notices noticeable movements, the location server is updated. The application of BLE locating modules is given priority by the system in order to save energy. After location data is gathered, ZigBee wireless transport modules are used to send it to the location server. In order to calculate precise positioning, the server combines this data with GPS information and applies triangulation algorithms. In contrast, the ZELPR_PSNode works on a similar principle but is optimized for outdoor or remote deployment scenarios. It shares components like the STM32 Processor Board and ZigBee Module but incorporates more capabilities like a GSM Modem for communication over cellular networks and an RJ45 Ethernet Module for wired connectivity. An LED Indicator provides a visual indicator on the node's status. Notably, this node operates powered by a Solar Power Supply, enhancing its autonomy and sustainability in outdoor environments.
BEST METHOD OF WORKING
To enable precise indoor-outdoor localization and continuous positioning data refinement with minimal power consumption, the ZELPT_PSNode, equipped with an STM32 Processor Board, a ZigBee Module, a GPS Module, a Bluetooth Module, a Motion Sensor, and a Power Supply, is used to facilitate the seamless integration of ZigBee technology with GPS and motion sensors.
For effective outside positioning and network connection, the ZELPR_PSNode, which is outfitted with an STM32 Processor Board, a ZigBee Module, a GSM Modem, an RJ45 Ethernet Module, an LED Indicator, and a Solar Power Supply, is utilized.
The innovation's central component, the ZigBee Modules built into both of the motes, allows for effective wireless communication within the network and makes it easier for location data to be transmitted between nodes and the central server for seamless indoor-outdoor positioning.
The ZELPT_PSNode's embedded GPS Module provides outdoor positioning data that, when paired with information from other sensors, allows for exact triangulation for indoor-outdoor localization.
The BLE locating module, which is also built into the ZELPT_PSNode, is used by the Bluetooth Module to determine the initial position of the system. This improves the accuracy and efficiency of the system in inside contexts where GPS signals may be scarce or nonexistent.
The GSM modem attached to the ZELPR_PSNode is used to enable communication over cellular networks, guaranteeing the system's operation in regions where ZigBee communication may be restricted and offering connectivity for the transmission of location data in remote or outdoor deployment scenarios.
