Abstract

A fire-extinguishing equipment includes: a fire-extinguishing apparatus which transmits electromagnetic waves in a predetermined output direction and discharges an extinguishing agent; an electromagnetic wave-receiver which is provided in an fire extinguishing object and receives the electromagnetic waves; and a controller which controls the fire-extinguishing apparatus to start to discharge the extinguishing agent when the output direction is set to a direction of the fire extinguishing object and the electromagnetic wave-receiver receives the electromagnetic waves.

First claim

The invention claimed is:

1. A fire-extinguishing equipment comprising:
a fire-extinguishing apparatus which transmits electromagnetic waves in a predetermined output direction and discharges an extinguishing agent in a discharge direction identical to the output direction;
an electromagnetic wave-receiver which is provided in a fire extinguishing object and receives the electromagnetic waves; and
a controller which controls the fire-extinguishing apparatus to start to discharge the extinguishing agent when the output direction is set to a direction of the fire extinguishing object and the electromagnetic wave-receiver receives the electromagnetic waves,
wherein the fire-extinguishing apparatus has (i) an electromagnetic wave-transmitter which transmits the electromagnetic waves and (ii) a nozzle from which the extinguishing agent is discharged, the electromagnetic wave-transmitter being fixed to the nozzle such that the output direction of the electromagnetic waves is identical to the discharge direction of the extinguishing agent from the nozzle, and
wherein the electromagnetic wave-receiver outputs a reception signal to the controller when the electromagnetic wave-receiver receives the electromagnetic waves from the electromagnetic wave-transmitter, and the controller outputs, to the fire-extinguishing apparatus, a fixing command for instructing the direction of the nozzle to be fixed when the controller receives the reception signal from electromagnetic wave-receiver.

2. The fire-extinguishing equipment according to claim 1 ,
wherein the output direction of the fire-extinguishing apparatus is adjustable, and
wherein the fire-extinguishing apparatus transmits the electromagnetic waves while the output direction of the fire-extinguishing apparatus is sequentially changed from an initial direction, and when the electromagnetic wave-receiver receives the electromagnetic waves, the controller starts to discharge the extinguishing agent in a state where the output direction is fixed to a direction in which the electromagnetic waves are received.

3. The fire-extinguishing equipment according to claim 1 , further comprising:
a fire detector provided in the fire extinguishing object,
wherein, when the fire detector detects an occurrence of a fire and the electromagnetic wave-receiver receives the electromagnetic waves, the controller further controls the fire-extinguishing apparatus to start to discharge the extinguishing agent.

4. The fire-extinguishing equipment according to claim 3 , further comprising a plurality of the fire extinguishing objects,
wherein the electromagnetic wave-receiver and the fire detector are provided in each of the fire extinguishing objects, and
wherein the controller stores in advance an initial output direction of the fire-extinguishing apparatus for each of the plurality of fire extinguishing objects, and sets the output direction of the fire-extinguishing apparatus to the initial output direction corresponding to the fire extinguishing object having the fire detector that detects the occurrence of the fire.

5. A fire-extinguishing equipment comprising:
a fire-extinguishing apparatus which is provided with an electromagnetic wave-receiver configured to receive electromagnetic waves, the fire-extinguishing apparatus configured to discharge an extinguishing agent in a discharge direction directly opposite to a receive direction of the electromagnetic waves; and
an electromagnetic wave-transmitter provided in a fire extinguishing object and configured to transmit electromagnetic waves in a predetermined output direction; and
a controller which controls the fire-extinguishing apparatus to start to discharge the extinguishing agent when the output direction is set to a direction of the fire-extinguishing apparatus and the electromagnetic wave-receiver receives the electromagnetic waves,
wherein the fire-extinguishing apparatus has a nozzle from which the extinguishing agent is discharged, the electromagnetic wave-receiver being fixed to the nozzle such that the output direction of the electromagnetic waves is directly opposite to the discharge direction of the extinguishing agent from the nozzle, and
wherein the electromagnetic wave-receiver outputs a reception signal to the controller when the electromagnetic wave-receiver receives the electromagnetic waves from the electromagnetic wave-transmitter, and the controller outputs, to the fire-extinguishing apparatus, a fixing command for instructing the direction of the nozzle to be fixed when the controller receives the reception signal from electromagnetic wave-receiver.

6. The fire-extinguishing equipment according to claim 1 ,
wherein in response to a determination that a fire is detected on the fire extinguishing object, the controller is configured to transmit a fire-extinguishing command to the fire-extinguishing apparatus including an initial direction corresponding to a position of the fire extinguishing object, and
wherein in response to receiving the fire-extinguishing command, the fire-extinguishing apparatus sequentially changes the output direction towards the initial direction corresponding to the position of the fire extinguishing object while the electromagnetic waves are transmitted, and
wherein in response to a determination that the electromagnetic wave-receiver receives the electromagnetic waves, the controller is configured to transmit the set position command such that the output direction is fixed to a direction in which the electromagnetic waves are received.
