A system for monitoring the operational status of a plurality of mechanical components, such as various bearings, speed reducers and the like. Each of the mechanical devices includes a respective local transmitter in electrical communication with various local sensors. Among the sensors which may be utilized are a temperature sensor and a shaft speed sensor, as well and an accelerometer for detecting vibration. The local transmitter receives information from the sensors and provides status information in a predetermined output format, such as a serial digital format. Unique electronic identifiers are assigned to respective of the local transmitters to facilitate selective communication with a central monitoring processor. As a result, the status information will be supplied to the central monitoring processor at predetermined times. Preferably, electrical communication between the local transmitters and the central monitoring processor is effected utilizing a bus line structure including a main trunk and a plurality of branch lines, wherein the respective local transmitters are connected to the branch lines. |
