Description

Pulse counting arrangement with a counting core made of a material with a rectangular shape Hysteresis behavior In the case of electronic counters with electron tubes or Transistors are constructed, has the identification of the count by the current-carrying or de-energized state has the disadvantage that the failure of the supply voltage in the information stored in the electronic meter is lost.

Another disadvantage is that when the electronic is idle Meter to store the information then present in the meter, always power must be expended.

When building an electronic meter with toroidal cores and diodes the large number of diodes is disadvantageous.

Other types of pulse reducers consist of perforated plate-shaped Ferrite material with a rectangular hysteresis loop and are used as counting transfluxors designated. Through the holes of these plates, windings are passed, which the individual Link magnetic areas together. The counting status is determined by the direction the magnetic fluxes around these holes, and each increment causes a corresponding change in the direction of flow. The operation of such counting transfluxors but always requires an upstream eternary reduction stage.

Is this ternary reduction stage like the one described at the beginning Binary scaler constructed, so this stage also has the disadvantages that in the event of a power failure the stored information is lost and when the meter is idle there is no powerless information Information storage is possible.

Although the stored in the magnetically working counting transfluxor Information is retained and stored without performance, apply to the off Ternary coaster and counting transfluxor already existing coaster unit identified disadvantages.

Even if the ternary scaler would work as a constant step-down element, i.e. with no-power information storage and without loss of information in the event of a failure of the supply voltage, the step-down consisting of the constant ternary converter and counting transfluxor has the disadvantage that the counting transfluxor returns after a certain number of input pulses (e.g. ten) must be brought into its starting position by a reset pulse. It is therefore not possible to connect a reduction stage, consisting of a permanent ternary reduction and counting transfluxor with a reduction ratio of 1: b, in series in order to achieve a reduction ratio of 1: ba for constantly applied input pulses. Intermittent reset pulses are always necessary for the individual counting transfluxors, and the input pulses that are present during the reset pulse are not taken into account for the counting process, which then leads to incorrect counting.

Another known possibility of pulse reduction is to in a ferrite plate with a rectangular hysteresis loop of various toroids To arrange diameter, each of which toroid z. B. from a set of holes consists of a central hole and several holes evenly spaced are arranged around the central hole and in which all holes of such a toroid have the same diameter. Magnetically more independent of one another through such a sentence and a winding is guided in its diameter of staggered toroids (e.g. ten). If now after magnetic saturation of all toroids of a set one through the winding flowing current has a magnetization direction opposite to the saturation state the toroid causes, then the number of remagnetized toroids by the Determines the amplitude of the current.

But also this z. B. trained for the decimal system counter with memory properties lacks the possibility of connecting z. B. c decimal counters constantly- applied input pulses in proportion 1: 10c to be reduced, since after every ten input pulses with each decimal counter by means of a reset pulse all toroids of a set in the same direction in terms of direction magnetic saturation must be brought. The during the duration of the Reset pulse applied input pulses are not taken into account for counting and consequently lead to incorrect measurements. It's an arrangement too known that in a ferrite ring with a rectangular hysteresis loop even more Bores through the windings are passed, but only for storage purposes with non-destructive information retrieval and not, as according to what has been shown so far, can be used for counting purposes. The mode of operation corresponds to the arrangement that of a Zweilochtransfluxor, only with the difference that in the addition in the ferrite ring arranged holes guided output winding due to the Reverse magnetization around each hole closing magnetic flux a higher one Voltage is induced, which increases the internal resistance of the transfiuxor is equivalent to.

An electronic meter without the disadvantages mentioned, such as the performance-related information storage and the associated loss of information in the event of failure of the supply voltage as well as the fact that series connections of individual permanent coaster are not possible, is now created according to the invention, that a suitably drilled and provided with windings plate or disc made of a material with a rectangular hysteresis loop is used.

A preferred embodiment of the invention provides a disk with a centric hole. In the disc ring there are now more, axially Directional 3 - n bores, with n = 1, 2, 3, 4 ..., all of which are in turn through further bores are interconnected, provided. In addition, there are bores in the radial direction provided, which from the outer circumference of the disc ring to the 3 - n axial bores bump. In all axial bores and in those that connect them to one another, as well as the last-mentioned bores, windings are accommodated.

The counting status is reversed by the direction of the magnetic fluxes the axial holes shown. As a result, remains in this in the invention Ber Wise manufactured counter core the once entered information even in case of failure the operating voltage, it is therefore a powerless information storage possible, and also by the fact that the fluxes in the counting core in the axial and radial plane close, the input impulses steady, i.e. without an intervening one Reset pulse are counted. Furthermore, there are no further switching elements for the construction are required, the overall structure is very space-saving.

The axial bores contain the windings that receive the counting pulses be fed; through the holes connecting the axial holes are the Windings to which the zeroing pulse is applied. In the radial direction from the outer circumference of the disc ring on the 3 - n-th axial bore An output winding is housed in the bore.

The windings to which the counting pulses are fed are now connected to one another without the interposition of any active or passive switching elements in such a way that the windings mi -1- 3p, m2 -t- 3 p and m8 + 3 p with ral = 1, rrez = 2, % = 3 and p = 0, 1, 2, 3, 4 ... are connected in series.

The windings to which the zeroing pulse is applied are all connected in series. The series connection is to be provided in such a way that the magnetic Flow course between the 3 - n-th and the first axial bore in opposite directions the remaining rivers.

The exact guidance of the individual windings and details about the flow profile can be taken from the following description of an exemplary embodiment emerged.

For the exemplary embodiment, a counter core with n = 3, that is nine axial holes selected. In Fig. 1 and 2 is a counting core 11 in front and side views with the axial bores 1_ to 10., the bores running in the radial direction 12 to 20 and the bores 21 to 21 connecting the axial bores 1_ to 9 229 shown.

For the initial state is from F i g. 5 shows the course of the magnetic fluxes 0 to 09 on the face of the counter core, shown by arrows, from FIG. 6 after the in F i g. 5 indicated section EF the course of 03 and 08 can be seen inside the counter core. The course of the flows 0 ″ e2, 04 to 07 and 09 in the interior of the counter core corresponds to that given for the initial state in FIG. 6 for the two flows 03 and 08.

F i g. 7 shows the arrangement of the counting pulse windings W1 to Ws, which are guided through the axial bores 1 to 9 and the radial bores 12 to 20.

From Fig. 8 is after the in F i g. 7 specified section 1-K, the The exact course of the counting pulse windings W., and W9 can be seen.

According to the information ml + 3 p, m2 + 3 p and m3 + 3 p with Ml = 1, M2 = 2, m, = 3 and p = 0, 1, 2, 3 ... are the windings W1, W4 , W7, the windings W2, W5, W8 and the windings Ws, WB, W9 connected in series and on the one hand connected to common ground, on the other hand connected to the terminals 30, 31 and 32, to which the successive counting pulses are applied.

In Fig. 9 is the section GH according to FIG. 1 with the arrangement of the winding where shown in bore 21. Through all the bores 22 to 29 connecting the axial bores and the radial bores 12 to 20 , a winding Wo is guided in the manner as shown in FIG. 9 can be seen. All windings Wo are shown in FIG. 10 and 11 are connected to one another and, on the one hand, to ground and, on the other hand, to terminal 33, that a negative pulse is applied to terminal 33, which is shown in FIG. 5 and 6 sets the flow course specified for the initial state, the flow course between the bores 1_-2, 2-3, 3_-4, 4-5, 5-f, b _-_ 7, _7-_8 and $ -9 so in the same direction, between the holes 9-1_ is opposite to this but.

F i g. 12 shows the counting core in a front view with the counting pulse windings W1 to W9, the output winding W12, which is led through hole 12 and is connected to ground on the one hand and to terminal 34 on the other hand, and the flow curve 01 to 09 for the initial state shown by arrows. The successive negative input pulses must now be fed to terminals 30, 31 and 32 in a cyclical sequence.

A first negative input pulse at terminal 30 causes, via winding W1, the fluxes 01 and 09 to reverse and to close counterclockwise on the front side and clockwise on the rear side, viewed from the front side. The rivers 01 and 09, of which, before the first input pulse, the river 09 has closed around the bore 21 connecting the axial bores 1 and _9, the flow 01 has closed around the bore 22 connecting the axial bores 1 and 2, which is therefore in the moving in the axial plane, now close in the radial plane at the front and rear of the counter core.

With the first input pulse, the rivers are now also energized around windings W4 and W7. But since the excitation is measured in such a way that the Coercive field strength only in one ring area of two adjacent axial ones Drilling is exceeded, no reversal of flows 04 and 07 is possible.

In Fig. 13 the flux distributions are on the face of the meter core shown how they adjust themselves after the first input pulse.

With a second negative input pulse, which now has to be fed to terminal 31, the flows 01 and 02 close counterclockwise on the front side, clockwise, viewed from the front side, on the back of the counter core. The flux curve has now been rotated from 0 to the radial plane, and the flux 09 closes again in the axial plane, but in the opposite direction compared to the curve before the first input pulse.

Also now no more rivers are reversed, although at the same time via the windings WS and W, an excitation occurred.

In Fig. 14 is the course of the river on the face of the counter core the second input pulse.

The third negative input pulse reaches terminal 32 and reverses the flows (P3 and 04, the fourth negative input pulse must be applied again to terminal 30 and reverses the flows 04 and $ 5. After the eighth negative input pulse, that of terminal 31 is supplied, a flux distribution is established at the end face of the counter core as shown in FIG.

The ninth negative input pulse, which is fed to terminal 32, reverses rivers 08 and 09. With this flux reversal from 0 $ and 09 it is in winding W "induces a voltage i11. This voltage serves as an output voltage and can at the terminal 34 z. B. can be removed to control a second counter core. The flux distribution that occurs after the ninth input pulse is shown in F. i g. 16 shown.

A comparison of FIG. 16 with FIG. 5 shows that now, so after nine input pulses, the initial state of the flux distribution is set again Has. With this counter core, a pulse reduction of 1: 9 can be achieved. A tenth negative input pulse has the same effect as the first input pulse.

So there is the possibility to do so in chronological order input pulses that are constantly applied to terminals 30, 31 and 32 continuously dem Feeding the counting core without interrupting the counting process by intermittent reset pulses having to interrupt.

From the description of the switching arrangement and its mode of operation goes shows that one assumed for the initial state also in the opposite direction Flow distribution that does not affect the mode of action, only the flow directions must together with the direction of winding of the individual windings, set once and then to be kept. Rather, it is possible that the current sequence of the flux reversal, in the example described with negative input pulses from river 01 to 02, 03, 04 etc., i.e. clockwise, by positive input pulses can reverse, so z. B. from 05 to 04, 03 etc., which means that with the counter core can be counted up and down.

It can also be seen that the central bore 10 for the function is not essential to the circuit. But you can save material and weight be left.

Depending on the number of axial bores, the various reduction ratios can now be achieved. With variation of n in the range 1 to 10 and thus the number 3 - n of the axial bores from 3 to 30 , the reduction ratios are 1: 3, 1: 6, 1: 9, 1:12, 1:15, 1:18, 1:21, 1:24, 1:27 and 1:30 were obtained. In addition, further reduction ratios can be achieved in that an output winding is provided not only at the 3rd-n-th axial bore, but also at the 1- n-th and 2-n-th axial bores. In a counter core with z. B. n = 5, if the axial bores 1 h = 5, 2 - n = 10 and 3 - n = 15 output windings are provided, a reduction ratio of 1: 5 can be achieved. All three output windings must be led to another output that is common to all three. At this common output, an output pulse can then be picked up after every fifth input pulse, and after fifteen input pulses the counter core has reached its initial state again. If a11 these possibilities are used, sixteen different reduction ratios, namely 1: 2 to 1:10, 1:12, 1:15, 1 : 18, 1:21, 1:24, 1:27 and 1:30.
