Abstract

A monitoring system for combined heat and power (CHP) units (1) has a main monitoring computer (2) at a remote central location connected to the CHP units (3). Data is processed and energy management information, as well as repair and maintenance procedures, can be derived by the remote and local computers (2, 3). Energy management information can also be obtained locally by means of a PC connected by a dial-up or network link (7) to a data access device (4b) of the local computer (3).

Claims

1. A power equipment monitoring system for monitoring performance data of individual power equipment units, said system comprising sensors (1d) associated with each said unit (1), a data collection and processing device (4a) local to each said unit adapted to receive and process data from the respective sensors, monitoring equipment (2) adapted to receive data from each data collection and processing device (3) for fault and maintenance monitoring purposes, characterized by the provision of a data access device (4b) associated with each data collection and processing device (4a), said data access device (4b) being accessible remotely, separately from the monitoring equipment (2) to provide a display, using a remote computer (8), of data from a selected said data collection and processing device (3) characterized in that the data access device is arranged to store data from the data collection and processing device (4a) in a format which can be utilized to generate the said display at the remote computer using an internet web browser.

2. The system according to claim 1 characterised in that there is a respective data access device (4b) for each data collection and processing device (4a).

3. The system according to claim 1 characterised in that the data access device (4b) is disposed locally to the data collection and processing device (4a).

4. The system according to claim 1 further in combination with power equipment units comprising combined heat and power (CHP) units.

5. The system at claim 4 including multiple power equipment units wherein performance data of each individual power equipment units is also monitored by the system.
