Abstract

PROBLEM TO BE SOLVED: To quickly and exactly detect fire source, by constituting the device rotating a fire source sensor capable of controlling scanning speed, slowing down the speed after detecting the target fire source, and scanning again the vicinity of the fire source. SOLUTION: A fire source sensor 1 is provided with a detection element 2, a computer 5 connected with the detection element 2, a view field angle control plate 9, horizontal direction rotation means, etc. The fire source sensor 1 is scanned with higher speed than normal scanning speed and wider view angle θH controlled by a view angle control plate 9. When the detection element 2 detects heat ray from the fire source 15, the computer 5 gets the output as input and stores the fire source position in the memory. Scanning is continued and the first scanning is finished. Then, the fire source sensor 1 returns to the vicinity of the stored fire source position, and changes the scanning speed to slower rescanning speed obtained by operation and the view angle to narrower view angle θL according to the scanning speed. The output is inputted in the computer 5 from the detection element at this moment. The computer 5 specifies the location of the fire source 15 based on the input.

2. Description of the Related Art A fire source sensor is provided with a detecting element such as a pyroelectric element, and monitors a fire while rotating horizontally at a predetermined angle. Then, when a fire occurs and the fire source sensor detects the fire source, the detection output is transmitted to the control panel.

When a pyroelectric element is used to measure the temperature of a fire source, the detection output of the pyroelectric element is small and thus is greatly affected by external noise. For this reason, it is difficult to obtain accurate fire information, which causes false reports and unreported reports. Therefore, in order to solve this problem, a detection output from the pyroelectric element is transmitted to a control panel via a noise filter.

When a noise filter is used, noise is removed, but output responsiveness deteriorates. That is, when the detection output of the pyroelectric element passes through the noise filter, the output waveform changes, and returns to the original output waveform after a lapse of a predetermined time. This predetermined time is referred to as the rising time of the output waveform, and this time is predetermined by the performance of the noise filter or the like.

ある。
For this reason, the fire source cannot be accurately detected unless the time during which the fire source can be measured within the viewing angle, that is, the time during which the fire source can be monitored is longer than the rise time of the output waveform. Further, in order to accurately detect the position of the fire source, it is necessary to narrow the viewing angle. Therefore, when scanning with a narrow viewing angle, scanning at a high speed makes it impossible to accurately detect a fire source, so that the scanning must be performed at a low speed. However, low-speed scanning is problematic because it takes too much time to complete scanning.

The case where the viewing angle is different between the list scanning speed and the rescanning speed has been described. However, the gain may be corrected by setting the viewing angle at both scanning speeds to be the same as described below. That is, when the fire source monitorable time TH (s) at the scan list scanning speed VH (rad / s) is shorter than the rise time t (s) of the output waveform from the noise filter, the output level is gain-corrected. The output level may be the same as that at a scanning speed VL (rad / s) lower than the list scanning speed. This gain correction GH is obtained by the ratio of the fire source monitoring possible time TH to the output waveform rise time t (s), that is, GH = t / TH.
