Document Type and Number:
WIPO Patent Application WO/2012/006789
Kind Code:
A1
Abstract:
A counting device comprises a signal wheel (1) driven by an equipment to be measured. The signal wheel (1) is coaxially provided with at least one group of holes. Each group of holes is composed of multiple holes, and the holes are provided with the inductors (11) which have different numerical values. An induction mechanism is provided with contacts (31) which have the same number as hole groups on the signal wheel (1), and is used for sensing the inductors (11) and acquiring the inducted signal, and the signal is transferred to a signal processor by a signal wire (2). According to the accepted single signal value and/or continuous signal values, the signal processor is able to determine the number of movement unit distance and movement direction of the equipment to be measured.
