Definitions

  • optical sensors that can detect columns of smoke that arise in the event of a forest fire.
  • These sensors are, for example, rotatable cameras, which, however, have the disadvantage that they are less effective at night and are susceptible to incorrect detection, for example in the event of clouds of dust as a result of agricultural activities.
  • optical systems can usually only recognize the forest fire when the forest fire has already progressed and the columns of smoke are visible over greater distances.
  • Monitoring from a high orbit by means of an IR camera built into a satellite has the disadvantage that the resolution of the cameras over the great distances prevents forest fires from being recognized in the early phase.
  • a satellite is also expensive to purchase and maintain, especially when the satellite is launched.
  • This system has the disadvantage that the control terminal triggers the alarm and must have a powerful RF unit for this.
  • the sensors require a GPS unit that constantly sends a signal to the control terminal, so the power consumption of the sensors is high and the service life of the energy sources (batteries) of the sensors is limited.
  • the ACK signal generation unit has a processor and a memory. Processor and memory are standard components and are therefore inexpensive to manufacture.
  • the first gateway and the second gateway are combined with a plurality of mesh gateway devices and at least one of the mesh gateway devices has no direct IP connection.
  • Mesh gateways consist of a combination of the first gateways and the second gateways.
  • the mesh gateways communicate with one another using a multi-hop radio network, and at least one mesh gateway is connected to the network server using the standard Internet protocol.
  • the second gateway is provided for communication by means of a standard IP connection and using the LoRaWAN protocol with the network server. At least one of the first gateways communicates directly with a second gateway. The second gateway sends the data from a terminal device directly to the network server using an Internet protocol.
  • This type of communication and division of the gateways into two types of gateways significantly expand the LoRaWAN network, whereby standard LoRaWAN-compatible end devices can still be used, which can be distributed and networked far in impassable areas that cannot be reached with conventional radio networks. These end devices are any commercially available devices that do not have to be adapted in order to use the advantages of the mesh network.
  • the object is also achieved by means of the method for the early detection of a forest fire.
  • the ACK signal is sent from the first gateway to the terminal.
  • the ACK signal ensures that a message from the terminal to a gateway has been correctly transmitted to the gateway.
  • the end device does not have to have a permanently active download / receive window and therefore has to be permanently active.
  • the power consumption is reduced and the service life of the terminal is increased.
  • Another significant advantage is that the direct sending of the ACK signal means that the time specified in the terminal for receiving the ACK signal is not exceeded. If the gateway (as provided for in the LoRaWAN standard) were to wait for the response from the network server, this would lead to a runtime being exceeded (RX1 / RX2) in the end device (timeout), which can lead to communication being aborted.
  • the first gateway forwards the message to a second gateway and / or the network server.
  • the first gateway and second gateway are connected to one another via a meshed multi-hop network, so that the front-end gateway does not need a direct connection while it is communicating with the end devices.
  • This also extends the range of the LoRaWAN network, because the front-end gateway is connected to the border gateway via the meshed multi-hop network and can therefore forward the data from the end devices to the Internet network server.
  • the ACK signal is generated and / or sent by a front-end gateway (FGD).
  • FIG. 7 schematically shows an embodiment of the LoRaWAN network 1, into which the forest fire early detection system 10 according to the invention is integrated.
  • the front-end gateways FGD and border gateways G2 described in FIGS. 5 a - c and 6 a - c are combined in one device.
  • These mesh gateways MDGn consist of a combination of the front-end gateways FGDn and the border gateways G2.
  • the mesh gateways MDGn communicate with one another by means of a multi-hop radio network MHF and at least one mesh gateway MDG is connected to the network server NS via a cable connection WN using the standard Internet protocol IP.
  • a mesh gateway MDGn After receiving a message from a terminal EDn, a mesh gateway MDGn sends an ACK signal ACK to the terminal EDn that sent the message.
