MEASURING SYSTEM FOR DIAGNOSIS EXECUTING TIME

摘要

PURPOSE:To easily and accurately measure the diagnostic time by carrying out a diagnostic process after a function executing process via a pseudo load function means of an off-line monitor device which is started with a timer interruption. CONSTITUTION:An off-line monitor device 10 is started with a timer interruption and carries out a monitor action of the high priority. Then a pseudo load function executing means 12 performs the pseudo execution of a load function for a period set by a load factor setting means 13. Then a diagnosis executing means 14 a diagnostic process of the lowest priority in the remaining timer period and the executions are carried out by both means 12 and 14 or an execution is done by the means 14 in each timer cycle period before the next monitor action is performed in a timer interruption period. Thus it is possible via such an off-line execution to avoid such an inconvenient case where the diagnostic function is kept interrupted owing to the execution of a function of the high priority. Then the diagnostic time is measured easily and accurately by a timepiece device of a CPU.
