Description

Mechanical digital code disc electromagnetic converter

The utility model is that a kind of machinery is counted converts the special code memory to, and the mechanical digital dish magnetoelastic transducer that can directly export, adopt this converter can realize machinery numeration transmission automatically in real time, on the electricity meter counter especially for watt-hour meter, after the conversion of this device, to spend in real time and show that converting number to exports, and can realize the function of automatic data logging, and can realize computer networking, Radio Data-transmission etc.

At present, various converter of the prior art, can only convert the amount of being converted to one or several pulse output whenever to be transformed into an amount, can not directly represent natural number, if will obtain natural number, then must advanced horizontal pulse count, as photoelectric commutator, carrying out pulse recording must be gone to finish by a cover electronic circuit (as digital circuit or single-chip microcomputer), and just must cause the rising of cost with electronic circuit, reliability reduces, have a power failure to need additional supplies (as battery) to keep data, will cause the difficulty promoted in actual use, particularly for civilian product (as watt-hour meter), with regard to one of cost, the user just can't bear this expensive expense (about about 1,000 yuan).

The purpose of this utility model is in order to overcome above-mentioned shortcoming, workout cost, reliability and the problem of safeguarding the aspect, designed a kind of Hall circuit of using the data-switching of mechanical type numeration has been become specific group code output, passive, non-contact type mechanical digital disk magnetoelastic transducer.

The purpose of this utility model is achieved in that the principle of work according to Hall element, when on Hall element, having corresponding magnetic field to pass through, signal output is promptly arranged after the Hall element energized, have or not magnetic field, just corresponding have a no signal, this just is equivalent to Hall element also is an information storage device, utilize this principle, available at least 4 Hall elements combination, when several magnet steel by necessarily regularly arranged (arranging) by the difference of ten natural numbers 0～9 with the Hall element of diverse location near the time, can make 0～9 natural number be transformed into array output by the sign indicating number (0 and 1) of Hall element output, the utility model be with mutually not the phase code character represent ten natural numbers of 0-9.

Magnet steel sticked on (character wheel can be cylindrical on each character wheel of mechanical type register, also can be tabular), at least 4 magnet steel on each character wheel, the position that these magnet steel are pasted is that arrangement position and the code character by every at least 4 Hall elements determines, and between the Hall element on circumference apart angle be 36 ° integral multiple, when each of register turns over a natural number like this, just will make magnet steel on circumference, rotate 36 °, and Hall element is (at least 4 of the Hall element) that is fixed on the fixed head, in the time of will appearing at different natural numbers like this, be on the different angle position, different group code output will appear in Hall element, convert 10 natural numbers to 10 different special code outputs thereby reached, if with each the equal way like this on the mechanical counter, can reach from the data-switching of reading window or pointer indication and become corresponding group code output.Again because the output information (0 or 1) of Hall element is only relevant with the magnet steel position, and there is not the transfer process of its electrical information, so just can reach when not carrying group code, just can Hall element not switched on, in case when needing the output group code, energized is exportable group code to adding correspondent voltage on the Hall element, can not have frictional rotation relatively between Hall element of the present utility model and the character wheel.

Below in conjunction with accompanying drawing the utility model is described in further detail.
