Abstract
The utility model discloses a gear type counter electronic counting device. Under the precondition that the structures of the original instrument and the original meter and the metering mode are not changed, by using simple technology, a reading gear (5) is additionally provided with a sensing chip of a capacitance element (1) (a resistor or an inductance element) which is embedded with ten different quantity values; the sensing chip synchronously rotates with the reading gear (5), so an electric brush which is arranged on a meter outer shell (8) contacts different copper sheets (3) on the chip to form different loops; thereby, different voltages, different currents or different frequency signals are obtained to achieve the purpose that the corresponding data on a gear type counter is identified.
Description
The utility model relates to a kind of numeral accumulative total, reading device that applies to the gear type instrument and meter.
At present, the gear type counter extensively applies in the mechanical type instrument and meter, as electric energy meter, water meter, gas meter, tachometer gage or the like.This class instrument is in product up-gradation with to when undergoing technological transformation with instrument, and what at first run into is problem how to discern cumulative amount, and existing common way is that Hall element is installed on gear, draws pulse signal and is handled, stored by CPU.But there are a lot of problems in the method: the one, changed the metering method of former instrument and meter, and to when undergoing technological transformation, increased error source with instrument; The 2nd, the signal processing circuit complexity has increased cost; The 3rd, be not easy to the technological transformation in the usefulness instrument, the waste that has increased resource; The 4th, on some special instrument, prevent cheating, poor anti jamming capability; The 5th, on some long-term instrument of all working, its reliability is difficult to guarantee.
The purpose of this utility model provides a kind of under the prerequisite that does not change original instrument structure and metering method, adopt simple technology, the gear type counter electronical reading device of the required strong interference immunity of signal Processing, precision height, electric current that error is little, voltage, frequency signal can be provided.
The technical solution adopted in the utility model is:
This device is the chip of the cylinder table shape that an additional center is a cylindrical hole on the reading gear of original instrument, and pylon upper part diameter and post are high to have the inner bottom surface of dialling wooden fork to be complementary with the meter reading gear.Going up the equal circumference branch at chip bottom surface (anchor ring) has ten mean lines, embeds the capacity cell of different values on every mean line respectively, and also available resistance or inductance element substitute.One end of the capacity cell of these ten different values all links together with the copper sheathing that is fixedly mounted in chip center's through hole.What be connected respectively with the other end of ten capacity cells is ten mutually isolated "T"-shaped copper sheets, and copper sheet is embedded on the external peripheral surface of this chip bottom surface respectively uniformly.This chip is to have the one side of dialling wooden fork to fixedly connected with the reading gear, and the central copper axle of reading gear just in time is passed in the copper sheathing in chip center's through hole, and this central copper axle is drawn an electrode, makes an end shared electrode of ten capacity cells by copper sheathing.On chip with the reading gear of instrument dial the wooden fork relevant position, have two and dial the wooden fork holes so that the wooden fork of dialling on the reading gear passes, stir the corresponding rotation of gear of being responsible for the next bit counting by its original carry mode, thereby finish carry work.Also be fixedly connected with the brush that a spring copper sheet is processed on the relevant position of meter case, brush is drawn another electrode thus.The other end of brush always contacts with one of ten copper sheets on the chip.Along with the rotation of reading gear, chip also rotates synchronously, and when the reading gear rotated 36 °, brush just contacted with corresponding copper sheet on the chip, forms a corresponding loop, produces the signal of a correspondence.If the reading gear rotates a week (promptly 360 °), brush contacts respectively with ten copper sheets, forms ten different loops, produces the signal of ten different values, thereby reaches the purpose of corresponding data on the identification gear type counter.
The gear type counter electronical reading device that the utility model proposes, be to install specific sensing chip additional by simple process, thereby under structure that does not change former instrument and meter reading device and metering method prerequisite, reach low-cost to the update of measuring instrument and meter and for transformation in the usefulness instrument.Simultaneously, this device can carry out interim reading, and is not only low in energy consumption, the reliability height, and anti-cheating performance, antijamming capability are strengthened, and do not change the accuracy class of former measuring instrument.
