Problems solved by technology

With the development of the national economy, computer remote network reading applications are becoming more and more widely used. Usually, position sensors and electronic memory are added to mechanical transmission instruments to meet the needs of remote readings. The position sensors are composed of reed switches, Hall or Wiegand sensors. , while the electronic memory needs to be powered on for a long time, its disadvantage is that the anti-interference is poor, and it is easy to cause the loss of the counting signal and cause the electromechanical data to be out of sync.

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Fig. 1 to Fig. 8 show an embodiment of the mechanical counter with electromagnetic induction coding 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 the condition of non-contact. The present invention installs several inductance coils 5 along the circumferential direction on the outer edge of the counting wheel 1, and forms an oscillating circuit with the capacitor 6, and embeds a metal conductive substance 8 of a certain shape in the counting wheel 1 along the circumferential direction.

[0026] The electromagnetic induction coding mechanical counter of the present invention includes a plurality of counting wheels 1 with counting wheel shafts 3 , the counting wheels 1 are connected with a carry control...

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...
