Abstract
A controller is provided with a plurality of CPUs and temperature sensors disposed in the vicinity of the CPUs, individually. The CPUs reciprocally read temperature data detected by the temperature sensors. When the read temperature data exceed a predetermined threshold, it is determined that the CPUs are likely to undergo thermal runaway, and the CPUs are then stopped.
Claims4
A controller comprising:
- a plurality of CPUs;
- and
- temperature sensors disposed in the vicinity of the CPUs, individually, wherein
- the CPUs are configured to reciprocally read temperature data detected by the temperature sensors, and
- the controller comprises a CPU stop section configured to determine that the CPUs are likely to undergo thermal runaway and then stop the CPUs if the temperature data read by the CPUs exceed a predetermined threshold.
