Example Embodiment

[0025] The present invention will be further described in detail below with reference to the embodiments of the drawings.

[0026] Figures 1 to 8 show an embodiment of the electromagnetic induction coding mechanical counter of the present invention. According to the principle of electromagnetic induction, the invention uses electronic technology to read the synchronous data of the mechanical counter under non-contact conditions. In the present invention, a plurality of inductance coils 5 are installed along the circumferential direction on the outer edge of the counting wheel 1 and form an oscillating circuit with the capacitor 6, and a metal conductive material 8 of a certain shape is embedded in the counting wheel 1 along the circumferential direction.

[0027] The electromagnetic induction coding mechanical counter of the present invention includes a plurality of counting wheels 1 with a counting wheel shaft 3, the counting wheel 1 is connected with a carry control transmission...

Abstract

The EMI-coded mechanical counter comprises: a counting wheel embedded conductive metal, a carryover control gear wheel, some inductance coils every with capacitor arranged outside of the counting wheel, a circuit board included a waveform oscillation trigger circuit and reading circuit and communication circuit and a SCM. Wherein, the embedded metal can be arranged as concentric closed ring or spiral or other shape. This invention is simple and reliable, and benefit to data auto-collection and information management.

Description

technical field [0001] The invention relates to the field of counting devices, in particular to an electromagnetic induction coded mechanical counter that uses electromagnetic induction eddy current attenuation oscillation technology to realize conversion and identification of electronic signals of traditional mechanical counters. It is widely used in the fields of data acquisition and data communication of automation devices such as electric meters, water meters, and gas meters. Background technique [0002] The current traditional mechanical counter is composed of a counting wheel and a transfer wheel controlled by carry. For example, the Chinese patent application No. 02259101.X is a utility model patent for "a mechanical counting device with an electric code output interface". Composed of output and data encoders, the counting wheel rotates relative to the position detection and data encoders. The mechanical counting wheel is used for counting and storing data, and the...
