INTELLIGENT AUTOMATIC FIRE WARNING SYSTEM

摘要

PURPOSE:To reduce artificial misinformation and to improve reliability by setting the operational level of sensors in accordance with setting places. CONSTITUTION:The outputs of the sensors 1 are converted into digital multiple signals by repeaters 1a and transmitted to a receiver 2. A comparison discriminating means 22 compares the detection signals of respective sensors 1 which a multiplex transmission unit 25 in the receiver 2 has fetched with information data of a main storage means 21 at every sensor, and a warning means 3 is operated based on the compared result. Detection data being the output of the comparison discriminating means 22 is stored in a temporary storage means 23. When a data rewriting means 34 receives data updating signals by the operation of a data alternation setting switch, it allows the main storage means 21 to store and update updating data which can be obtained by adding previously set correction data to detection data stored in the temporary storage means 23.
