DE1076738B - Arrangement for generating a pulse combination assigned to a signal - Google Patents

Description

GERMAN

The invention relates to an arrangement for generating a pulse combination assigned to a signal, in which a constant number of pulses is given within a constant time and the total time is divided into m time segments, of which η time segments are occupied with pulses, see above

that pulse combinations can be generated, with

both the number of time segments m and the number of time segments occupied with pulses η ίο can be selected arbitrarily.

The invention is based on the object of simplifying such a device in terms of circuitry in such a way that that at any time an unlimited expansion of the facility with a minimum of technical effort Funding is possible.

According to the invention, this object is achieved in that in an arrangement with m time segments and η time segments occupied with pulses, a control line system is present which has intersection points to each of which a pulse generator is connected, each of which allows the setting of associated memories, which in turn the intersection points Prepare the logic circuits assigned to the control line system so that when the pulses determined by the wiring arrive from a clock generator, the pulse telegram assigned to the crossing points is sent to a common output bus.

The device according to the invention offers several advantages over the previously known arrangements. Not only does it allow an arbitrary choice with a small expenditure of technical means, it also eliminates the stencils previously required. The subject of the application can be expanded to an unlimited extent at any time simply by adding individual memories and logic circuits, with the wiring always remaining clear, even in the case of an extensive system. A special feature of the subject of the application is that, regardless of the size of the system, only a single output manifold is required, while a large number of output lines are required in older facilities. Compared to the previously known arrangements, the subject matter of the invention also offers the advantage that the coding takes place with clock pulses. Through contacts, as they are required in older facilities, are therefore omitted in the subject of the application. Furthermore, the time clocks can also be generated with electronic counting chains, which is why no large control outputs, such as those required by relay circuits, are required. The operational safety of the new facility is high, arrangement for generating

Applicant:

Voigt & Haeffner Aktiengesellschaft,
Frankfurt / M., Hanauer Landstr. 142-172

Dipl.-Ing. Georg-Siegfried Licht, Hanover,
has been named as the inventor

because in the event of a diode failure (loss of the blocking effect) or if only a single storage device fails no pulse combinations come about, and no pulse or wrong code is sent.

The new facility is to be explained in more detail using the block diagram. It consists of the clock generator 1, several signal generators z. B. 2 a, 2 b, 2 c, also a number of memories 3, 4, 5, 6 and finally from the "And" / "Or" circuits 7, 8, 9. The mode of operation of the new device is as follows:

If, for example, the signal transmitter 2a is actuated, then this causes the memory 4 and 5, and although in the sense of the arrows shown there. The consequence of this is that the “ands / words” switching combination 7 a voltage is present. If the timer 1 now uses the control lines 10, 11, the Transmission of the signal combination II, III, then the element 7 responds, and the pulse combination is delivered via the common output busbar 12.

The signal given at the intersection A of the control lines 13, 15 for the memories 4, 5 sets the memories so that the "And" / "Or" combination 7 located at the same intersection of the memories is marked. Shortly thereafter, the timer 1 is started by a starting device, not shown. When the clock pulses arrive via the control lines ΙΟ, 11, a pulse telegram corresponding to intersection A is sent to the output bus 12 common to all “And” / “Or” combinations. The same occurs when the signal generator 2 b, Ic are actuated. A pulse diagram is then output which corresponds to the intersection point B or C.

The new device is generally useful for converting a signal, e.g. B. of messages or Commands in telecontrol technology in pulse combinations.

Patent claims: 1. Arrangement for generating a pulse combination assigned to a signal, in which a constant number of pulses is given within a constant time and the total time is divided into m time segments, of which η time segments are occupied with pulses, so that Pulse combinations can be generated, whereby both the number of time segments m and the number of time segments η occupied by pulses can be selected arbitrarily, characterized in that in an arrangement with m (e.g. m = 3) time segments and _n (e.g. B. »= 2) time segments occupied with pulses a control line system (13, 14, 15, 16) is present, the intersection points (A, B ₁ C) , to each of which a pulse generator (2 a, 2 b, 2 c) is connected, each of which allows the setting of assigned memories (e.g. 4, 5 through 2a), which in turn prepare logic circuits (7, 8, 9) assigned to the crossing points of the control line system so that when the pulses determined by the wiring arrive from a Time clock (1) the pulse telegram assigned to the crossing points is sent to a common output bus line (12). 2. Arrangement according to claim 1, characterized in that for preparing the logic circuits η groups of binary memories are provided, of which each group (m-n + i) contains individual memories. 3. Arrangement according to claim 1 and 2, characterized in that a pulse combination can only be formed if one of the "and" / "or" combinations representing the logic circuits from each of the memory groups has a marking potential and at the same time from the clock during 11 a voltage is applied for periods of time determined by the type of wiring.
