PURPOSE:To transfer easily information required extremely for the user, by installing a sensor for abnormality detection with priority levels added. CONSTITUTION:When the sensor for anomaly detection operates, information is read into input memory part 7 through sensor connection terminal part 6, and the output is applied to comparing circuit 9. The output of circuit 9 is stored in the operation memory. The number of these storage contents is stored in counter 13. If another sensor input occurs under this state, its contents are stored in memory part 7; however, since these contents are different from contents of operation memory 8, they are read into memory 8 and register 10 by the output of comparing circuit 9. Next, the number of pulses proportional to the output of register 10 is recorded in counter 14. Contents of counters 13 and 14 are compared with each other; and if the value of counter 14 is smaller, channel comparator 15 is operated to return the channel to the origin. At this time, a control signal is issued, and channel selection is performed again to reproduce the preferential channel. |
