Abstract
A monitoring system for monitoring equipment has first data processing means for executing a primary, critical task and second data processing means for executing a secondary, non-critical task. The second data processing means receives its power supply from the first data processing means via protective circuitry so as to prevent electrical failures in the second data processing means from affecting operation of the first data processing means.
Claims17
A data processing system configured for processing input data, wherein:
- the data processing system comprises first data processing means;
- and wherein
- the first data processing means is configured for performing a primary data processing task;
- and wherein
- the first data processing means has a first power input for connection to a power supply, and a first power output;
- and wherein
- the first data processing means has a protective circuit between the first power input and the first power output, and
- the protective circuit is configured for preventing a power consumer connected to the first power output from affecting operation of the first data processing means via the first power input.
A data processing system configured for processing input data, wherein:
- the data processing system comprises first data processing means and second data processing means;
- and wherein
- the first data processing means is configured for performing a primary data processing task;
- and wherein
- the second data processing means is configured for performing a secondary data processing task;
- and wherein
- the first data processing means has a first data input for receiving the input data;
- and wherein

A monitoring system for monitoring an operational condition of equipment, the monitoring system comprising:
- a sensor for generating a sensor signal indicative of the operational condition;
- and
- a data processing system comprises first data processing means;
- wherein
- the first data processing means is configured for performing a primary data processing task;
- and wherein
- the first data processing means has a first power input for connection to a power supply, and a first power output;
- and wherein
- the first data processing means has a protective circuit between the first power input and the first power output, and
- the protective circuit is configured for preventing a power consumer connected to the first power output from affecting operation of the first data processing means via the first power input, and wherein
- the data processing system is configured for monitoring the operational condition of the equipment on the basis of the input data representative of the sensor signal.
