ABSTRACT:
In a system for monitoring trash compactors, each monitoring unit associated with a trash compactor comprises a transducer for sensing hydraulic pressure, for generating an analog signal from the sensed pressure, and for converting the analog signal to a frequency signal, and a microprocessor. The microprocessor compares pressure signal values generated from the frequency signal over timed intervals to a specified value indicative of a compaction. The microprocessor also compares the maximum pressure signal value generated therefrom, under certain conditions, to a threshold value indicative of the trash compactor having a substantially empty compactor and to a threshold value indicative of the trash compactor having a substantially full container. Whenever a specified, plural number of substantially empty compactions have been determined and whenever a specified, plural number of substantially full compactions have been determined, status signals are transmitted by the system to a central computer, via a modem.
