Definitions

  • the invention relates to a communication method capable of transmitting mutual data via multiple UWB (ultra wideband) nodes in closed environments.
  • UWB ultra wideband
  • Wi-Fi Wireless Fidelity
  • Bluetooth is used as a short distance communication method. It provides very low power consumption and is a low cost method.
  • a station device is required for communication with Wi-Fi. With this station device, it offers a wide area of influence.
  • GSM is an open, digital cellular radio network. It is used for voice calls, text messages and data calculation.
  • Analogue or digital systems can be used for radio communication.
  • Analogue systems provide voice communication and are not preferred for data exchange.
  • Digital systems are a faster and more efficient method for voice and data communication. In this way, uninterrupted communication can be provided in very large and large areas.
  • GSM's signal strength is affected in closed areas and signal strength is interrupted.
  • Wi-Fi and Bluetooth signals have a much more limited range of effect than RF signals and are interrupted more frequently, so these signals cannot be used over much wider distances.
  • Some disadvantages of current RF communication methods are that the radio broadcast can be distorted by false signals and personal data can be accessed more easily without permission. In general, an inspection is carried out in the area where communication is desired and may require pre-installation.
  • UWB signals cause very little interference with existing radio systems. Since UWB signals have a low power spectral density, they resemble noise and this reduces the probability of detection of UWB signals and secure communication can be provided. Devices with UWB technology have a long battery life. They are much less affected by multipath channel effects and jamming effects.
  • UWB signals have the advantage of penetrating through many objects (e.g. walls, doors, etc.) in closed areas.
  • US2022210631A1 relates to method and device for device discovery using UWB.
  • EP3866524A1 relates to UWB communication node and system for facilitating secure placement of UWB communication nodes.
  • EPl 124211 A3 relates to a wireless telemetry system integrated with a broadband network.
  • the International patent document numbered WO2022213183A1 relates to ultra- wideband (UWB) communication methods and systems.
  • the object of the present invention is to provide an UWB-based closed environment communication method which does not require pre-installation, communication starts by leaving devices in the newly discovered environment during the entrance to the cave or closed area, with these easily portable devices, the location of the devices can be changed modularly, the devices can be left fixed or new devices can be added to the environment, the user exploring in the cave or closed area has the opportunity to communicate with a user in the communication network or in the information centre, and data, voice, picture and image information can be shared end-to-end in the environment.

  • Figure 2 Schematic view of the communication data transfer protocol of the communication method according to the invention, showing the interrupts and actions of the nodes.
  • FIG 3 A schematic view of the communication data transfer protocol of the communication method according to the invention, in which data is transferred in one direction.
  • Figure 4 Schematic view of the communication data transfer protocol in which bidirectional data transfer occurs in the communication method according to the invention.
  • the communication method according to the invention comprises the steps
  • the first UWB communication node (2) listening to the neighbouring UWB communication node (2) which is further away from the outside (further inside), if no data is received from the neighbouring UWB communication node (2) which is further away from the outside, recognising itself as the farthest UWB communication node (2) and transmitting the data package (4) with data transmission priority to the previous UWB communication node (2) which is closer to the outside, If the data transmission priority order is from outside to inside, the first UWB communication node (2) listening to the neighbouring UWB communication node (2) which is closer to the outside (further out) than itself, if no data is received from the neighbouring UWB communication node (2) which is closer to the outside than itself, recognising itself as the nearest UWB communication node (2) and transmitting the data package (4) to the next UWB communication node (2) which is further away from the outside with data transmission priority,
  • the relevant UWB communication node (2) receiving this data and setting its timer to t+1 according to the UWB communication node (2) from which it receives data,
  • Each UWB communication node (2) transmitting the priority data received at time t in the direction of data transmission priority to its neighbouring nodes together with the data it holds, if any.
  • the aim of the invention is to provide a network structure that can transmit data through more than one UWB communication node (2).
  • UWB technology it will be possible to communicate between the information centre (1) and the mobile UWB node (3) in areas where inter-operator communication is required (such as caves, warehouses, labyrinths) without the need for pre-installation.
  • messages, voice, pictures and images will be shared between devices. If there are UWB positioning modules in the environment, positioning information can also be sent to the information centre.
  • the invention covers end-to-end communication by placing UWB communication nodes (2) in succession at a distance that can communicate with each other.
  • These modules can be placed at predetermined points or can be placed as a new node in the environment so as not to be disconnected from the communication network during operation.
  • These modules which will provide wireless communication, have the capacity to operate for a long time thanks to their low energy consumption.
  • Slotted ALOHA will be used to control message transmission and controller process timing. Each ALOHA time slot has the same length. In order to create a constant data flow without data loss due to UWB signal collision, only a single unit needs to transmit data between neighbouring nodes. This problem requires both UWB nodes to transmit data at an allocated time and neighbouring UWB nodes to listen at the same time. As a result of Slotted ALOHA, collisions of UWB messages will be eliminated/minimised.
  • each UWB communication node (2) has a processing cycle that starts and ends according to the allocated time sequence. This processing cycle comprises one session. In each session, there are 4 allocated time slots for the desired operations. Each time slot has an allocated start and execution time to maintain synchronisation.
  • the total number of UWB nodes between UWB nodes determines the length of the communication time, as it creates extra nodes and extra data packages (4). Even if there are more than two neighbours, the node ignores the messages of non-consecutive neighbours. However, the module needs to take UWB message collision into account and create an empty session for each neighbour.
  • FIG. 1 There is an information centre (1) outside the indoor area. Inside the indoor area, there are fixed wireless UWB communication nodes (2). Mobile UWB nodes (3) are mobile and perform reconnaissance. Mobile UWB nodes (3) transmit the received data to the nearest UWB communication node (2).
  • each row represents a UWB communication node (2) and each column represents a time slot.
  • the example shows an instance with 5 UWB communication nodes (2) and 10 time slots.
  • the top row represents the information centre (1) and the bottom row represents the farthest (deepest in the cave) UWB communication node (2).
  • the priority of transmitting data packages (4) per unit time to avoid overlapping UWB messages is, in this implementation, from the inside to the outside (5). In other words, the data package (4) transmitted outwards by the UWB communication node (2) located at the deepest part of the cave has priority.
  • Data transmission from outside to inside (6) is not prioritised and the transmission of this data package (4) will wait for the time period in which the relevant UWB communication node (2) will talk, i.e. transmit data.
  • the information centre (1) (node shown in the first line) transmits a data package (4) to the UWB communication node (2) (node shown in the second line) at the entrance of the cave.
  • the UWB communication node (2) shown in the second line, understands that the data package (4) is not prioritised. Therefore, it does not set its timer with the received data and waits for the data package from the next node.
  • the UWB communication node (2) (the node shown in the last line) at the deepest part of the cave transmits the data package (4) received from the mobile communication nodes (3) to the previous UWB communication node (2) (the node shown in the fourth line).
  • the UWB communication node (2) shown in the fourth line receives the data from the deepest UWB communication node (2) shown in the last line.
  • the data package (4) also contains the information that the data has priority. Therefore, the node in the fourth row transfers this data to the node in the third row at t+1 (second time slot).
  • the node in the third queue realises that the data has priority and transfers it to the node in the second queue at time t+2 (third time slot).
  • time t+2 (i.e. in the third time slot), with the data package received from the node in the third slot, it shares the data received at time t+3 (i.e. in the fourth time slot) with the node in the first slot and the node in the third slot, realising that the priority is from inside to outside.
  • it transfers the data received from the first-order node to the third-order node and the data received from the third-order node to the first-order node at t+3.
  • it is determined in which time period and multiples each node will transmit data. While data transmission from inside to outside (5) is completed in 4 time slots, data transmission from outside to inside (6) is completed in 10 time slots. Thus, data collision is prevented.
