<p>PURPOSE:To easily discriminate an alarm display factor displayed on an alarm display window by using an analyzer to analyze many alarm signals for analysis of a scrum factor or the scrum generating time, etc., and displaying these analysis results on an alarm display device. CONSTITUTION:Plural trouble factor signals 1 are inputed to an alarm display unit 2 and the output signal of the unit 2 is inputed to an alarm display device 3 consisting of plural alarm display window, etc. Thus a lamp blinks on an alarm display window. The output signal of the unit 2 is also sent to an alarm display/analysis device 4. This device 4 consists of an input device 5, an input discriminating device 6, a logical arithmetic unit 7, a scrum discriminating device 8 which discriminates the presence or absence of a scrum based on the output signal of the device 6, a scrum factor collecting device 9 which stores the state of the scrum factor in a scrum state based on the output signal of the device 8, an after-scrum information collecting device 10 which stores an alarm ON state after the scrum state, an alarm display information display device 11 which displays the alarm display information, i.e., the output signals of both devices 9 and 10, and a print device 12.</p> |
