Abstract
A telemetry system for a surface maintenance machine such as a scrubber or a sweeper has a plurality of sensors which monitor machine operating conditions. The sensors are periodically scanned and repetitive outputs indicative of sensor condition are used to provide tone coded telemetry signals. The tone coded signals are modulated on a suitable carrier frequency and are sent to a receiver which is remote from the sensors. The receiver decodes the tone coded signals to provide a display of the conditions being monitored by the sensors. The tone coded outputs from the transmitter also include an identification of the particular machine which is providing information for the display at the receiver.
