The present invention discloses a method for monitoring an OS task of an RTOS microcomputer capable of sensing real time errors generated in a microcomputer. A method for monitoring other tasks according to the present invention comprises a) a step of setting two micro computer as a master (MC2) and a slave (MC1) and of determining the task complete condition of the master (MC2) and the slave (MC1) within the tolerance time of the set task and b) a step of executing resynchronization between the master (MC2) and the slave (MC1) when the errors having the over tolerance time are detected from the master (MC2) or the slave (MC1) according to a result determined in the step a) in a method for monitoring the OS task of the system using two microcomputers (MC1, MC2) including an independent real time operating system (RTOS). Therefore, the present invention senses real time errors generated in the microcomputer by monitoring the errors on which the OS task is not operated in the accurate time by the interference of an interrupt, the error of a timer for operating the OS, or the task having the high priority order. |
