TE is a test operation panel provided with test switches (not shown) operated during testing and a changeover switch SW for selecting a test target;
Reference numeral 2 denotes a television receiver that receives images transmitted from the ITV camera 1, and 53 a camera receiver that outputs a rotation signal to the camera rotation device 1a by operating a camera rotation switch (not shown) on the operation console 51. A rotation control unit 54 detects the rotation angle and elevation angle of the ITV camera 1 from the detection circuit of the camera rotation device 1a by operating a water cannon nozzle aiming switch (not shown) on the operation console 51, and detects the position coordinates of the fire spot. The position determination unit 55 is composed of an arithmetic device such as a microprocessor that calculates the position signal and outputs the position signal.

A water cannon aiming rotation control section 56 is a discharge control section that outputs a discharge control signal to the fire extinguishing water supply source 4 by operating a discharge switch (not shown) on the console 51. Further, 7 is a fire receiver that receives a fire signal from a fire detector or a manual notification device (not shown) provided along the object to be extinguished, or a notification from an emergency telephone or the like.

Next, the operation of the test apparatus shown in FIG. 1 will be explained, but first, the operation as a water cannon fire extinguishing system will be explained first. An image receiving switch (not shown) on the operation console 51 is turned on to receive the image of the ITV camera 1 on the receiver 52, and a camera rotation switch (not shown) on the operation console 51 is also turned on to control the camera rotation control section 53. Outputs a rotation signal. In response to this rotation signal, the camera rotation device 1a rotates the ITV camera 1 for measurement and monitoring in the left, right, up and down directions in order to photograph the object to be extinguished, and the ITV camera 1 rotates each part of the object to be extinguished. The images are sequentially displayed on the receiver 52.

[0010] In such a state, when the occurrence of a fire is notified via the fire receiver 7, the operator
monitor the condition of the object to be extinguished. When it is confirmed that the ITV camera 1 has captured the fire spot with the shooting aim by seeing the image of the fire spot reflected in the center of the screen of the receiver 52, the camera rotation switch (not shown) on the console 51 is turned off and the camera is turned off.

Next, the water cannon aiming rotation control section 55 detects the rotation angle signal and the elevation angle signal of the water cannon 3 from the detection circuit of the water cannon rotation device 3a, and compares them with the above calculation results. The aiming control signal is output to the water cannon rotating device 3a so that the difference becomes 0, and when the calculated value and the detected value become equal, the output of the aiming control signal is stopped and the rotating mechanism of the water cannon rotating device 3a operates. At the same time, completion of the aiming work is displayed on the console 51. When the operator turns on a discharge switch (not shown) on the operation console 51, the discharge control section 56 controls the water cannon 3.
The fire extinguishing water supply source 4 supplies fire extinguishing water to the water cannon 3 under the control of the discharge control signal, and the water cannon 3 supplies fire extinguishing water to the fire extinguishing water supply source 4. Spray water on the fire spot.

Next, the television whose operation has been explained above will be described.
The operation when testing a camera-linked water cannon fire extinguishing system according to the present invention will be explained using FIG. 2 as well.

As shown in FIG. 2, there are
A plurality of test targets TT are installed within the movable limit range of both the ITV camera 1 and the water cannon 3. Each test target TT is
It can be selected using the changeover switch SW on the test operation panel TE.

When starting a test, the operator first selects an arbitrary test target TT using the changeover switch SW on the test operation panel TE, and then operates a test switch (not shown). When the test switch is operated, the rotation angle and elevation angle signals of the ITV camera 1 corresponding to the position of the selected test target TT are output from the test operation panel TE to the camera rotation control unit 53. The dynamic control unit 53 is an IT
The camera rotation device 1a is rotationally controlled so that the V-camera 1 is directed toward the selected test target. At the same time, test operation panel T
From E, the rotation angle and elevation angle signals of the water cannon 3 corresponding to the position of the similarly selected test target TT are output to the water cannon aiming rotation control section 55, and as a result, the water cannon aiming rotation control section 55 controls the rotation of the water cannon rotation device 3a so as to direct the water cannon 3 toward the selected test target. Furthermore, an operation signal is given to the visible light laser LA from the test operation panel TE, and this causes the visible light laser LA attached coaxially to the water cannon 3 to operate, causing the water cannon 3 to face. Laser light is emitted in a certain direction.

If the fire extinguishing system is normal, the ITV camera 1 rotates the camera rotation device 1 under the control of the camera rotation control section 53.
The selected test target TT is rotated by
The TV camera 1 captures the image with its shooting sight, and at the same time, the water cannon 3 is also rotated by the water cannon rotation device 3a under the control of the water cannon aiming rotation control unit 55, and is attached to the water cannon 3. The visible light laser LA will irradiate the selected test target TT.

The operator observes the image receiver 52 and confirms that the selected test target TT has been captured by the ITV camera 1 with the shooting sight, and the laser beam from the visible laser LA is directed toward the test target TT. By checking the reflected light that is irradiated and reflected by the fire extinguisher,
It can be seen that the interlock between the camera 1 and the water cannon 3 can operate normally.

After the above test operation is completed, the operator can continue the test operation by selecting another test target using the changeover switch SW, if necessary.

In the above embodiment, the water cannon is directly used as a test target, the ITV camera is controlled so as to look directly at the water cannon, and the ITV camera is aimed at the direct light of the laser emitted from the water cannon. You can also check the functionality and accuracy by confirming that it has been captured.

Further, as the light emitting means, a light emitting device may be used which uses a lamp or the like as a light source and emits a beam of red, blue or yellow light.

[0021]

As described above, according to the present invention, by selecting the test target with the changeover switch, the television camera and the water cannon are automatically controlled to rotate toward the test target, and the water cannon is turned to the test target. When facing the target, light such as a laser beam is irradiated onto the test target using a light emitting means such as a visible light laser, and this is observed with a television camera that is also directed at the test target. Since it is possible to know that both water cannons are accurately aimed at the test target, there is an effect that the test can be conducted effectively without actually spraying water and damaging other equipment.
