Title:
SYSTEM AND METHOD OF POSITIONING INSIDE BUILDINGS
Document Type and Number:
WIPO Patent Application WO/2023/089362
Kind Code:
A1
Abstract:
The subject of the invention is a system for determining the position inside objects. It is characterized by the fact that it consists of radio probes (1, 2, 3,..., n) working in Bluetooth 5 technology arranged sequentially on the perimeter of the analyzed object, each of which contains a transmitting microcontroller and a receiving microcontroller, which are connected via a transmitting microcontroller with a Bluetooth 5 expansion card (4), and this one is connected by serial connection to the central unit (5) connected to the reconstructing server (7). A method for determining the position inside objects using the system. It is characterized in that from the transmitting microcontroller of radio probes (1, 2, 3,..., n) a communication packet with the user data range up to 31 bytes is released, containing the values of RSSI indicators of other scanned devices and the TX power parameter defining the transmit power of the antenna transmitting device, while by means of receiving microcontrollers from radio probes (1, 2, 3,..., n) sent signals are received from other radio probes (1, 2, 3,..., n), from which the receiving microcontrollers calculate RSSI index for the radio probe (1, 2, 3,..., n) from which the packet was sent, and then arranges the RSSI pointers at a fixed location of the data container according to the order number of the radio probe (1, 2, 3,..., n), and all communication packets sent by transmitting microcontrollers are updated by receiving microcontrollers located on the same laminate and are sent out with the help of transmitting microcontrollers from radio probes (1, 2, 3,..., n) working in the Bluetooth technology 5 arranged successively on the perimeter of the analyzed object, a radio signal with a communication packet with a user data range of up to 31 bytes is transmitted, and at irregular intervals it is scanned by the central unit (5), in which after receiving the data, the identification number of the transmitting microcontroller is checked and the received row is placed inside the matrix body in the position consistent with the ordinal number of the radio probe (1, 2, 3,..., n), while irregular intervals between scanning individual system elements cause independent refreshing individual rows of the matrix, while from the central unit (5) a matrix with a dimension of n x n and non-zero diagonal is sent to the reconstructing server (7) using the Apache Kafka data bus, while this data bus does not introduce any changes in the message and without disturbing the data structure and them to algorithms using Tikhonov regularization, Gauss-Newton method, the method of contour sets and artificial intelligence mechanisms, while the reconstruction based on the background matrix and the measurement matrix is presented in the form of a heat map in one of the server services (7).
