Definitions

  • the present invention relates to a system for monitoring a previously travelled pathway.
  • a system for monitoring a previously travelled pathway is a system whereby battery-powered wireless devices are deployed by a user at intervals while entering a potentially hostile area, and which can provide ongoing monitoring and reporting of the conditions along the pathway for the purpose of identifying potential threats to the user at their current location, to identify threats to the user's future exit pathway, to support finding a user in the event of them falling into difficulty and to support multiple pathways that monitor condition and relate the information to worker location.
  • a system for monitoring at least one previously travelled pathway comprising: a user device comprising means for interacting with a user; and node devices arranged to be deployed on a pathway as a user travels, the nodes further being arranged to communicate with at least one other node device, the user device or a device external to the system to reflect a change in a predetermined factor in the region of the deployed node device on the pathway.
  • the node device may respond to the proximity of other node devices or user devices.
  • the present invention provides a monitoring network having plural node devices provided, for example, by small battery powered sensors that are wirelessly connected to a unit carried by the user and optionally also connected wirelessly to other users or to a control centre outside of the risk zone.
  • the node devices are distributed by the user on the way into the risk zone and once deployed periodically broadcast one or more local factors, for example temperature, toxic substances, sound, movement of the node or movement in the vicinity of the node.
  • Information from the monitoring node devices can be shared between workers at the scene, and with control centre personnel to maintain a continuously updated picture of the conditions inside the risk zone.
  • Lighting may be incorporated in the node devices and can be triggered by a number of sources and can provide immediate visual clues to navigate towards an exit or towards a trapped worker.
  • Ranging information can be used to identify the closest node device, to report the progress of a rescuer towards the compromised worker, or the progress of a worker towards an exit, providing immediate audio or visual updates to the user, rescuer or a control centre.
  • Such ranging techniques can be applied to enhance the system further, using resolved distance between one or more user devices and one or more node devices to identify when a worker passes into or out of a risk zone where node devices have already been deployed by that worker, or previously deployed by another worker.
  • Figures 1 and 2 are schematic diagrams of example user devices and nodes that can be provided in a system according to the present invention.
  • Figure 3 is a drawing showing a possible scenario employing the present invention of the system.
  • FIG. 1 shown is a possible form of a User Device 1 and node device 3 for use in the invention, it includes the following features:
  • the User Device 1 containing both an integrated battery 2 an electronic circuit 2, one or more monitoring node devices 3 which may be temporarily clipped into the User Device.
  • Component 4 is the monitoring node inside the User Device and reference 5 shows a slot through which the nodes could be deployed.
  • a user interface 6 is provided through a display, indicator lights and/or an audio interface.
  • FIG. 2 shows another possible form of the User Device 1 and node device 3, and includes the following features:
  • the User Device 1 contains both an integrated battery 2 and electronic circuit 2 and one or more monitoring nodes 3 which may be temporarily clipped into the User Device.
  • Item 3 is the monitoring node device detached from the User Device.
  • a user interface 6 is provided through a display, indicator lights and/or an audio interface to enable a user to interact with, and operate, the invention.
  • Figure 3 shows a yet further example system according to the invention, in which the user device 1 is configured to be worn on a user's limb.
  • Components corresponding to those in the earlier examples have the same numbering.
  • a user will take the user device 1 into a hazardous situation, removing nodes 3 as they progress and placing them in appropriate locations.
  • the user device 1 may be arranged to dispense nodes 3 automatically at predetermined times and/or distances or when wireless connection with a previous node is determined to have dropped to a level which is likely soon to become unreliable.
  • Each node device 3 can wirelessly communicate either with the user device 1 , a device external to the main system, which may be a second user device, or a combination thereof, and/or may also communicate with each other.
  • the communication will generally be wireless and in accordance with one of a number of known standards of RF, Bluetooth (RTM) or similar types or customized to this application.
  • Each user node device 3 will usually have its own independent short or long term power supply that may or not be rechargeable.
  • each monitoring node device 3 can monitor for a factor that may compromise the path in which they have been placed, that parameter being, for example temperature, air quality, radiation or chemical contamination, and if an appropriate factor is detected or a parameter threshold exceeded then notification can be provided to its external communication source and/or the user component for appropriate action to be taken.
  • the node devices 3 may be arranged to detect the pressure or movement by objects or people. Either new or previously used node devices 3 may be reused and re-attached to the same or another user device 1.
  • the node devices 3 and user device 1 can be configured to automatically update one another with required information to build future pathway(s) associated with that worker. In this way, any node can be re-used or re-loaded by any worker through the single action of placing the node device into the user device, greatly simplifying re-loading or re-use of node devices.
  • the system may be arranged to create multiple pathways by sharing of previously deployed node devices, whereby a user that operates within a certain distance of a node device previously deployed by another user may adopt that previously deployed node device into their own pathway. This allows the re-use of node devices previously deployed, avoiding the need to deploy multiple node devices along the main pathway into the risk area, for example along a main corridor.
  • the first entrant into a building can then deploy their node devices and other workers can adopt these shared node devices into their own pathway instead of deploying their own, thereby preserving their node devices for later use. If the system incorporates automatic deployment of node devices, then that deployment can be automatically inhibited along the shared pathway.
  • FIG. 4 shows a potential application of the system.
  • a firefighter 10 is fighting a primary fire 20.
  • the firefighter (10) has deployed a number of node devices 3 on entry to the fire zone forming a monitored pathway 40. Should a secondary fire source 50 breakthrough then it would trigger one of the monitoring node devices 3 to alert the firefighter of a potential risk to their exit.
  • a node is out of direct range to a User, it could pass signals via other node devices 3 in order to reach its intended destination.

Abstract

L'invention concerne un système de contrôle d'un chemin déjà parcouru. Le système comprend un dispositif d'utilisateur comprenant des moyens d'interaction avec un utilisateur et des dispositifs de nœuds agencés pour être déployés sur un chemin pendant le parcours d'un utilisateur. Les nœuds sont agencés pour communiquer avec au moins un autre dispositif de nœud ou le dispositif d'utilisateur ou un dispositif externe au système pour refléter un changement d'un facteur préétabli dans la zone du dispositif de nœud déployé sur le chemin.
