When the flame and the position where the flame is generated are detected by the conventional devices as described in (1) to (3) above, there are the following problems. (1) In the case of the surface scanning type detection device, it is necessary to perform image processing in order to extract the characteristics of the flame, but generally the image processing is complicated and therefore the device becomes expensive. Also, the sensor itself is generally expensive. If the image range of the sensor is less than the detection range, it is necessary to equip a plurality of sensors or change the detection direction of the sensor at all times, which is more expensive. Moreover, since the scanning mechanism (mechanism for changing the direction of the sensor) always operates, it is not preferable in terms of power saving, price, reliability and the like. (2) In the case of point scanning type detection device and line scanning type detection device,
Although an inexpensive sensor can be used, it is not preferable as in the above (1) because the scanning mechanism is always activated. Also,
Since the scanning method also sequentially scans regardless of the flame generation position, if a flame occurs at the position where the scanning ends, the next scan must be waited for, and the flame detection is delayed. An object of the present invention is to provide a flame position detection device that can be inexpensively configured and that can quickly and accurately detect a flame generation position.

As a result of taking the above-mentioned means, the following effects occur. According to the flame position detection device of the present invention, when a flame is detected by any one of the plurality of flame detection means, the cylindrical member is scan-driven so that all of the plurality of flame detection means detect the flame, Since the position of the flame is calculated based on the direction of the baseline, a plurality of inexpensive sensors are used as the flame detecting means, and the arrangement of these is as described above, and the flame is obtained by appropriately combining with the driving means. The detection range is constantly monitored without driving the driving means, and when a flame is generated, the driving means can drive the base line to quickly face the flame. Therefore, the position of the flame can be calculated based on the direction of the flame, and early detection of the fire occurrence and early determination of the fired position can be promoted.

Upon receiving the signal from any of the flame sensors 105 to 108, the flame detection calculation unit 131 outputs the flame detection output S1 to the outside. Further, the detection unit operation direction determination unit 132 is configured in advance by the flame sensor 1 of the first quadrant.
Operation direction corresponding to 05 (arrow 1 in FIG. 4 (b))
A signal indicating that the detection cylinder 100 is moved in the direction 15) is output to the detection unit scanning mechanism unit 122 of the scanning mechanism unit 12.

When the detection section operating direction determination section 132 receives a signal indicating that a flame has been detected from all the flame sensors 105 to 108, it stops outputting to the detection section scanning mechanism section 122 and the flame position calculation section. A command to calculate the flame position is sent to 135. At this time, as described above, the point E exists on the extension line of the base line f.

The flame position detecting device 1 is composed of the detecting unit 11, the scanning mechanism unit 12, the orientation sensor 15, and the control unit 13 for controlling these, which are shown in the above (1) and (2). Works as follows. (1) First, the baseline direction of the detection unit 11 is assumed to be held by the scanning mechanism unit 12 in such a direction as to be able to monitor the entire monitoring target range a by four quadrants. Then, when a flame is generated in the monitored range a, any of the flame sensors 105 to 108 installed in each quadrant immediately detects it. (2) Next, the scanning mechanism unit 12 moves the baseline f of the detection unit 11 toward the quadrant in which the flame is detected. Eventually, the flame sensor of the quadrant other than the quadrant in which the flame was first detected also flames. Will come to detect. At this time, the point where the flame is generated is on the extended surface of the partition plates 102 and 103 which divide the quadrant on which the flame sensors 105 to 108 for detecting the flame are installed. Here, as the operating direction of the scanning mechanism section 12, instead of the operating direction up to now, the scanning mechanism section 12 is operated in the direction of the phantom in which the flame is newly detected. (3) Eventually, flames are detected in all quadrants, and the scanning mechanism section 12 stops operating in this state. At this time, the base line f indicates the direction in which the flame is generated. The output of the orientation sensor 15 at this time indicates the orientation of the flame. Therefore, the flame position is derived from the orientation information, the mounting position of the detection unit 11, and the shape information of the monitoring target range a. When the flame is no longer detected in all quadrants, it is considered that the flame has disappeared, and the scanning mechanism unit 12 returns to the initial pointing direction.
