Device for triggering an event in phase with an angular position of a rotary component and application thereof |
摘要 |
An encoder delivers a pulse input signal in phase with equal angular steps of a rotary component, such as a toothed wheel driven by the crankshaft of an internal combustion engine. A missing tooth defines a reference position at which a synchronizing signal is also delivered. A counter is incremented by the pulse input signal and is reset by the synchronizing signal. A comparator compares the count in the counter with a number in a memory circuit to deliver a signal for triggering an event when the count in the counter coincides with the number in the memory circuit. The counter comprises a first counting circuit providing the least significant outputs of the counter and a second counting circuit providing the most significant outputs. The first counting circuit is reset by the input signal, and the second counting circuit by the synchronizing signal.
