System for a machine or plant having a large number of sensors and/or actuators
First Claim
1. A system for a machine having a large number of units selected from the group consisting of sensors and actuators, the system comprising:
- connecting cables;
at least one communications device connected to at least two of the units through said connecting cables, said communication device mounted on the machine, said communications device having at least one of a modulator/coder and a radio transmitter for transmitting sensor signals disposed downstream of said modulator/coder, and a radio receiver and a demodulator/decoder for receiving actuator drive signals disposed downstream of said demodulator/decoder;
a base station communicating via radio signals with said communications device, said base station having at least one of a radio receiver and a demodulator/decoder for receiving sensor signals disposed downstream of said radio receiver, and a modulator/coder with a radio transmitter for transmitting actuator drive signals disposed downstream of said radio transmitter; and
a central computer connected to said base station.

Abstract
A system is proposed for a machine or plant having a large number of sensors and/or actuators. At least one communications device is provided, to which at least two sensors and/or actuators are connected via short connecting cables, is mounted on the machine or plant. The communications device has a modulator/coder with a downstream radio transmitter for transmitting sensor signals, and/or has a radio receiver with a downstream demodulator/decoder for receiving actuator drive signals. The communications device communicates via radio signals with a base station, which is connected to a central computer for the machine or plant. The base station has a radio receiver with a downstream demodulator/decoder for receiving sensor signals, and/or has a modulator/coder with a downstream radio transmitter for transmitting actuator drive signals.
