Abstract
A control system is disclosed which permits information captured by each sensor to be sent exactly to a main controller and a fall in the level of sensor signals with time to be automatically compensated for with no need to make sensor signal lines long and without reducing the sensor monitoring accuracy and limiting the number of sensors used. The levels of signals from sensors connected to each of unit controllers are compared with slice levels. The results of comparisons are converted into a serial signal and then transmitted to the main controller. Each time the sensor signal level is monitored, the optimum slice level therefor is set.
