| 摘要 |
<p>This invention relates to data recording apparatus that includes a self-contained monitor (10) adapted for attachment to a machine to monitor one or more parameters of operation of the machine. The monitor includes a transducer (12) adapted to sense changes in state of one or more of the monitored parameters of machine operation and to convert the sensed change in parameter state to recordable machine parameter data, a data store (14) adapted to receive and store the data and a power supply (16) adapted to provide operating power to the transducer and data store. The data recording apparatus includes a data communication device externally of the monitor, which data communication device is adapted to supply the monitor with power to enable data communication between the monitor and the external data communication device.</p> |
