Unmanned vehicle, system, and method for initiating a fire extinguishing action

An unmanned vehicle for initiating a fire extinguishing action, comprising:

• a vehicle sensor unit that is designed for detecting a fire parameter KF of a vehicle monitoring region,
• a vehicle communication unit for a signal exchange with a central unit having a central fire alarm system, or with a stationary fire detector, wherein the vehicle communication unit is designed for receiving an instruction signal SI that represents a reference fire status ZR for a fire detector monitoring region of the stationary fire detector, and a target location and/or a target region, and
• a navigation control unit,
• wherein the navigation control unit is designed for navigating the vehicle to the target location and/or to the target region, preferably in an autonomous manner, based on the received instruction signal SI,
• wherein the vehicle is configured for detecting the fire parameter KF in the form of a verification fire parameter KV of the fire monitoring region, at the target location or in the target region by the vehicle sensor unit, configured for determining a verification fire status ZV by evaluating the verification fire parameter KV, and designed and/or configured for initiating a fire extinguishing action if the verification fire status KV was determined,
• wherein the vehicle comprises a fire extinguishing unit for extinguishing a fire, wherein the vehicle is designed for carrying out a fire extinguishing action with the aid of the fire extinguishing unit,
• wherein the fire extinguishing unit comprises a nozzle, which is designed for discharging and spraying an extinguishing medium for extinguishing a fire, and an externally accessible output connector for making available extinguishing medium, wherein said output connector can be coupled to a mating connector of a stationary extinguishing device in order to make available extinguishing medium to the stationary extinguishing device, and
• wherein the fire extinguishing unit comprises a controllable triggering unit having a controllable valve, which is designed for controlling an extinguishing medium flow to the nozzle and/or the output connector, wherein the vehicle is designed for generating a triggering signal for the triggering unit and for controlling the triggering unit by the triggering signal such that the triggering unit releases an extinguishing medium flow to the nozzle and/or the output connector when the triggering unit is activated by the triggering signal, wherein the vehicle is designed for transmitting a signal, which represents the triggering time, at which the triggering unit releases the extinguishing medium flow, and/or a triggering period of the released extinguishing medium flow, to the central unit.

A method for initiating a fire extinguishing action, comprising the following steps:

• receiving an instruction signal SI by a vehicle communication unit of an unmanned vehicle, wherein a vehicle sensor unit of the vehicle is designed for detecting a fire parameter KF of a vehicle monitoring region, and wherein the instruction signal SI represents a reference fire status ZR for a fire detector monitoring region of a stationary fire detector, and a target location or a target region;
• navigating the vehicle to the target location or to the target region in an autonomous manner, based on the instruction signal SI received by the vehicle;
• detecting the fire parameter KF in the form of a verification fire parameter KV of the fire detector monitoring region, by the vehicle sensor unit;
• determining a verification fire status ZV by evaluating the verification fire parameter KV by the vehicle;
• and
• initiating a fire extinguishing action by the vehicle if the verification fire status KV was determined;
• wherein the method further comprises the following additional step, which is carried out prior to the reception of the instruction signal SI:
• transmitting the corresponding instruction signal SI to the vehicle communication unit of the vehicle by a signal transmitting unit of a central unit.
