いる（特願昭58−249141号）。(Prior Art) As a conventional flame detection device, the inventors of the present application have proposed that when a flame detector for overall monitoring detects the occurrence of a fire, a pair of fire source detection devices further detects the location of the fire source. It has been proposed to be applied to an automatic fire extinguishing system that directs the nozzle to the fire source position according to the calculation result based on the detection information from the source detection device and releases extinguishing liquid to extinguish the fire (Japanese Patent Application No. 58-249141). ).

し、対応する検出器を水平方向に走査して火源を
探索していた。 In this automatic fire extinguishing system, each of the pair of fire source detection devices includes a detector for detecting a fire source, a vertical control means for scanning the detector in a vertical direction, and a horizontal control means for scanning the detector in a horizontal direction. The vertical deflection angle of each detector is initially set to substantially directly downward, and when the fire detector detects a fire, the horizontal direction control means of each fire source detection device is driven. , the corresponding detector was scanning horizontally to search for the fire source.

同様に探索動作を繰り返し火源の位置を検出して
いた。 If the fire source is not detected by the above operations, the vertical direction control means of each fire source detection device is further driven to set the vertical deviation angle of the corresponding detector upward by a predetermined angle from directly below. , After completing the setting of the deflection angle, drive each horizontal direction control means, scan the corresponding detector in the horizontal direction to search for the fire source, and repeat the search operation in the same manner to detect the position of the fire source. Was.

定された各偏位角毎に一対の検出器を水平方向に
走査しており、垂直方向の指向角が火源位置に達
したとき、水平方向の走査で火源を検出してい
た。 That is, the vertical directivity angles of the pair of detectors are set upward by equal angles set in advance, and the pair of detectors is scanned in the horizontal direction at each set deflection angle. When the vertical pointing angle reached the fire source location, the fire source was detected by horizontal scanning.
（発明が解決しようとする問題点） しかしながら、火源検出装置の手前側から遠方
までの全ての監視区域内に亘つて検出器の垂直方
向の偏位角を予め設定した等角度ずつ偏位設定す
る場合には、以下の問題があつた。(Problem to be Solved by the Invention) However, the vertical deviation angle of the detector is set in equal angle increments within the entire monitoring area from the near side to the far side of the fire source detection device. When doing so, the following problems arose.
即ち、監視区域内に設置した火源検出装置の手
前側に位置する炎に標準を合せ、火災と判断する
最小の炎の大きさを基準火源と想定し、この標準

査幅が広くなり、基準火源と等しい大きさの炎を
検出できなくなる虞れがあり、更に単位偏位角を
再分割して炎を検出しなければならなかつた。 In other words, the standard is set to the flame located in front of the fire source detection device installed in the monitoring area, and the minimum size of the flame that is judged to be a fire is assumed to be the standard fire source, and the standard fire source is set to detect this standard fire source. When the vertical deflection angle is set to vertically deflect the detector, the vertical deflection angle of the detector is sequentially set upward, and the detector is directed toward the far side of the monitoring area to detect the farthest floor surface. When scanning, the scanning width of the floor surface scanned per unit deviation angle becomes wider, and there is a risk that flames of the same size as the reference fire source cannot be detected, and the unit deviation angle is further subdivided. the flame had to be detected.
また逆に、監視区域の遠方に位置する基準火源

出ができなかつた。 Conversely, if you align the standard with a reference fire source located far away from the monitoring area and set the deflection angle so that it can detect the distant reference fire source, the vertical pointing angle of the detector will move towards the front of the monitoring area. When the fire source is directed, the scanning width of the floor surface scanned per unit deflection angle becomes narrower than necessary, and the number of scans increases, making it impossible to efficiently detect the fire source.

A flame detection device comprising a control means and a horizontal control means for horizontally scanning a detector,
In order to be able to efficiently detect fire sources over the entire area within the monitoring area, we have previously assumed multiple minimum standard fire sources that can be identified as flames on the floor and walls within the monitoring area, and set standards that are adjacent to each other. A deflection angle setting section for setting a vertical deflection angle on a beam line connecting one upper end and the other lower end of the fire source is provided, and a vertical direction control means is provided based on a command from the deflection angle setting section. This is how it was done.

The fire source detection device 4 also includes a detector 4a for detecting a fire source, a vertical control means 4b (for example, a pyroelectric element, etc.) for vertically controlling the detector 4a, and a horizontal control means for controlling the detector 4a in the horizontal direction. The horizontal direction control means 4c is provided. Each of the vertical direction control means 3b, 4b and the horizontal direction control means 3c, 4c has a corresponding detector 3.
The position of the fire source is detected by controlling the detectors 3a and 4a independently and scanning each detector 3a and 4a vertically and horizontally in response to a command from a control section, which will be described later. Reference numeral 5 denotes a nozzle device installed at the center of rotation of the pedestal 2, which includes a nozzle 5a that emits extinguishing liquid, and a radiation direction control means 5b that directs the nozzle 5a to the fire source position detected by the fire source detection devices 3 and 4. and a radiation state control means 5c that controls the radiation state by adjusting the opening degree of the injection port of the nozzle 5a according to the distance to the fire source. Reference numeral 6 denotes a direction control means, which controls the rotation of the pedestal 2 in the horizontal direction, thereby controlling the fire source detection device 3,

Area No. 1 and Area No. 2 will be monitored exclusively. When any of the detection elements built into the fire detector 9 detects a fire, it sends detection information to the circuit section 10. That is, detection information from the fire detector 9 is input to the control section 17 via the input interface 15.

Then, the direction control means 6 is driven to rotate the pedestal 2 so that the fire source detection devices 3, 4 and the nozzle device 5 face the fire area, for example, area No. 2. Further, the control section 17 has a built-in deflection angle setting section 14 for setting the vertical deflection angle of the detectors 3a and 4a.

For example, while controlling the horizontal direction control means 3c and 4c, the rotation angle of the pedestal 2 is adjusted by controlling the direction control means 6 to direct the detectors 3a and 4a and the nozzle 5a together in the front direction. Further, as shown in FIG. 5B, the vertical direction control means 3b and 4b are controlled to direct the vertical deviation angle of the detector 4a directly downward, and the vertical deviation angle of the detector 3a is monitored. The deflection angle is set approximately toward the center of the area, for example, at a deflection angle θ4. In the block 22, the fire detector 9 monitors the occurrence of fire in each monitoring area. For example, as shown in FIG. 5A, the fire detector 9 monitors the occurrence of fire in monitoring area No.
If a fire occurs in
is detected, the process proceeds from block 22 to block 23, and the direction control means 6 is driven. Direction control means 6
The mount 2 is rotated horizontally by the drive of the detector 3.
a, 4a and the nozzle 5a are integrally opposed to each other in the direction of area No. 2, and in the block 24, the detectors 3a,
4a to perform flame detection operation. That is, the deflection angle in the vertical direction is such that the detector 4a is directly downward, and the detector 3a is
is set at the deviation angle θ4, and while maintaining the vertical deviation angle of each detector 3a, 4a at the initial value by operating the horizontal direction control means 3c, 4c, the area No. 2 is sequentially moved. Scan horizontally. In block 25, it is determined whether flame has been detected by detector 3a. If no flame has been detected, the process proceeds to block 26, in which the detection information from detector 4a is decoded. Block 2
6, if flame detection information cannot be obtained, the process proceeds to block 27, and the vertical direction control means 3b, 4
b is driven to deviate the vertical directivity angles of each of the detectors 3a and 4a upward by a predetermined angle.
That is, as shown in FIG. 3, the vertical deflection angle of the detector 4a is set from the downward direction to the deflection angle θ1, and the detector 3a is set to the deflection angle θ5 from the deflection angle θ4. Further, the process proceeds to block 24, in which the horizontal direction control means 3b and 4b are driven to horizontally scan the area No. 2 while maintaining the vertical deviation angles of the detectors 3a and 4a at .theta.5 and .theta.1, respectively.

う。 Similarly, the vertical deviation angle of each detector 3a, 4a is set upward by a predetermined angle stepwise based on a preset deviation angle setting program, and detection is performed at each deviation angle. Vessels 3a, 4a
Scan the area No. 2 horizontally and repeat the flame search operation. Here, if the search operation of the detectors 3a and 4a progresses and the detector 4a detects a flame,
Proceeding from block 26 to block 28, the horizontal control means 3c and vertical control means 3b of the fire source detection device 3 are driven to direct the detector 3a in the direction of the flame. In block 30, the size of the flame is determined based on information from detectors 3a and 4a.
If the size of the flame is less than a predetermined size, it is determined that there is no fire, and the process returns to block 21, where the initial state is set and the occurrence of a fire is monitored. If the size of the flame is larger than a predetermined size in block 30, it is determined that there is a fire, and the process proceeds to block 31, where the buzzer 7 is sounded and the lamp 8 is turned on to display an alarm. Further, the process proceeds to block 32, where the direction control means 6 is driven to control the rotation of the pedestal 2, so that the fire source detection devices 3, 4 and the nozzle device 5 are integrally opposed to each other in the direction of the flame. Block 3
3, readjustment is performed by deviating the pointing angles of the detectors 3a and 4a from the flame as the mount 2 rotates, and the horizontal direction control means 3c and 4c are operated to adjust the orientation angles of the detectors 3a and 4a. Point it in the direction of the flame. In the block 34, detection information is collected with the detectors 3a and 4a facing the flame.
The exact location of the flame based on the detection information from 4a,
That is, the distance and height to the flame are calculated. The nozzle device 5 is controlled based on the result of this calculation, and in block 35, the radiation direction control means 5b is operated to control the vertical direction angle of the nozzle 5a and direct the injection port in the direction of the flame. In block 36, the radiation state control means 5c is operated to adjust the opening degree of the injection port of the nozzle 5a and control the discharge state in which extinguishing liquid is discharged. In block 37, the fire pump 12 is operated by starting the motor 13, and the fire extinguishing liquid is supplied to the nozzle 5a.
and begin firefighting operations. Block 38
, it is monitored whether the fire has been extinguished based on the detection information from the fire detector 9. If the fire is not completely extinguished, the process returns from block 38 to block 34 and the detection information from detectors 3a and 4a is checked again. The fire source position is calculated by collecting information, and based on the calculation result, the radiation direction and radiation state of the nozzle 5a are readjusted to continue firefighting operations. When block 38 confirms that the fire is completely extinguished, block 39
Then, the motor 13 and fire pump 12 are turned off to stop firefighting. In block 40, the buzzer 7 and lamp 8 are turned off to stop the alarm, and the process returns to block 21, where the directivity angles of the detectors 3a and 4a are set to the initial state and fire monitoring is performed.

効果が得られる。(Effects of the Invention) As described above, according to the present invention, there is provided a detector for detecting a fire source generated in a monitoring area, a vertical direction control means for scanning the detector in the vertical direction, and a horizontal control means for scanning the detector in the vertical direction. In a flame detection device equipped with a horizontal direction control means that scans in the direction, a plurality of minimum reference fire sources that are determined as flames are assumed in advance on the floor and wall surfaces in the monitoring area, and reference fire sources that are adjacent to each other are assumed. A deflection angle setting section for setting a vertical deflection angle on a beam line connecting the upper end of one side and the lower end of the other side is provided, and the vertical direction control means is driven based on a command from the deflection angle setting section. By doing so, it is possible to efficiently search for the fire source throughout the monitoring area.

The accurate location of the fire source can be calculated based on the detected information. That is,
The position of the fire source can be detected based on the detection information obtained at the same time as the fire source search, and the unique effect of expediting fire extinguishing operations is obtained.
