Abstract

A failure detection apparatus (10) includes a RAM (125) and a controller (122) configured to execute processing related to detection of a physical quantity in a predetermined sampling period (T₁). The RAM (125) includes partitioned areas generated by partitioning the entire area of the RAM (125). The controller (122) is configured to execute sequential failure detection on a portion of the partitioned areas during a time when the controller (122) is not executing the processing in each of the sampling periods (T₁).

Claims

1. A failure detection apparatus comprising:

a RAM; and

a controller configured to execute processing related to detection of a physical quantity in a predetermined sampling period;

wherein the RAM comprises a plurality of partitioned areas generated by partitioning an entire area of the RAM; and

wherein the controller is configured to execute sequential failure detection on a portion of the plurality of partitioned areas during a time when the controller is not executing the processing in each of a plurality of the sampling periods.

2. The failure detection apparatus of claim 1, wherein the controller is configured to execute failure detection on a priority basis on a specific partitioned area among the plurality of partitioned areas.

3. The failure detection apparatus of claim 2, wherein the specific partitioned area belongs to a calculation result storage area configured to store a result of calculation processing executed by the controller.

4. The failure detection apparatus of claim 1, wherein the controller is configured to execute processing related to detection of a property of a liquid.

5. A failure detection method to be executed by a failure detection apparatus comprising a RAM,

wherein the RAM comprises a plurality of partitioned areas generated by partitioning an entire area of the RAM;

wherein the failure detection method comprises;

executing processing related to detection of a physical quantity in a predetermined sampling period; and

executing sequential failure detection on a portion of the plurality of partitioned areas during a time when the processing is not being executed in each of a plurality of the sampling periods.

6. A non-transitory computer readable recording medium having stored thereon instructions to be executed on a failure detection apparatus comprising a RAM that includes a plurality of partitioned areas generated by partitioning an entire area of the RAM, the instructions causing the failure detection apparatus to execute the steps of:

executing processing related to detection of a physical quantity in a predetermined sampling period; and

executing sequential failure detection on a portion of the plurality of partitioned areas during a time when the processing is not being executed in each of a plurality of the sampling periods.
