Method for carrying out an automatic selective election in a multi-digit decadic system and Circuit for their implementation

The invention "relates to a method of implementation an automatic selective choice in a multi-digit decadic system and a circuit for the implementation this method, especially for use in extensive radio station networks.

In the "previously" known solutions, a selective Choice of the location of a control system on fixed, possibly "mobile subscribers" are both Pulse codes as well as codes with tone frequencies are used.

In systems with pulse codes, the choice of subscriber in the case of individual calls is made with the help of reading of transmitted pulses and in the case of a group selection with the help of an evaluation of the number the transmitted pulses and their groups, including the evaluation of different pulse lengths, as well as of impulse pauses between individual impulse groups.

In these systems there is a requirement for a precise Pulse shape and fairly precise pauses between the pulse groups. This requirement is only substantial with a " complicated circuit for the formation of the pulse groups and their transmission on the transmitter side and only with a relatively complicated circuit of a decoding device on the receiver side to realize where further the introduction of an automatic preparation of the enterprise would be difficult can. These systems are more suitable for subscriber selection in wired devices.

As far as “systems of selective choice with use” are concerned is about codes in tone frequencies, basically two selection methods can be used.

With the first method, especially for individual Calls is suitable either corresponds to any frequency number the number of an individual participant or this

Hummer represents a combination of two or more (sound frequencies that act ion at the receiver With the help of filters and other frequency circles can be distinguished. .

The second method is that the control station in the same way encoded digits of the individual Sends out decades with a subsequent code.

In the first method, there is a disadvantage in one large size and complexity of the code setup for a large number of participants, especially on the sender side. Difficulties can also arise here with intermodulation frequencies arise.

With the other method, the basic disadvantage is that that by the previously known decoding methods Signals in two or several consecutive ones the same * digits cannot be broken down,

Both methods have the common disadvantage "that it is not possible »in a simple way with one Participants can quickly change the number as it is Example in rail transport where the number of the train set on the station of the unit of action must be alternated on different trains of one pictorial Streclcenfah ^ planes (Schatibild) is used.

In both cases it would be a difficult one Replacement of filters or a very complicated switch system.

known devices for selective dialing by any method with codes in code frequencies have not yet solved the implementation of an automatic preparation of the operation, especially is advantageous for Vjiseribahn dispatching.

The invention eliminates the disadvantages mentioned and provides the advantages of a unique and operational automatic selective election.

This method can be used for selective group voting in place of at least one of the numerical decades, a frequency combination of the signal of the group selection is formed and transmitted is, in the case of a match in the digits of the other decades a connection with the participants of all digits of the selected decade is ensured is, the locking signal at these subscribers only causes a display of the group connection.

the lock signal C is decoded in the same way. Its logical "1" becomes the second system of connection paths of the decoding matrix DMC for digits about an iris of the logical. "Or" function PLC the auxiliary signals (D 127, D 128) are transmitted to the third input of the control memory PR (T 104, T 105). It deletes this memory. Thereby the logical "1" becomes at the common output of the decoding matrix DKD for decades in parallel via the regenerator RG- (T 122) to the first inputs of the circuit for the logical "And" function of digit selection (D 103, D 104) and des Circle for the logical "And" function HG · the group selection (D 105, D 106), where the logical "1" at the exit 0 "comes the gate slip and this with consideration to the logical "1" from the memory PG- the group selection (T 120, T 121) including the regenerator RG (T 122) ..

When the match of the »pale, which is blocked by the blocking signal C, the memory PS of the agreement remains in the overturned state, which means that ^{the logic" 1 "remains at the output A M} even after the function of the signal has ended.

Here it is also necessary to state that on output A "a logic" 1 ", which at the zeroing signal '

This memory tilts into the Kullage, which could not result from the agreement of the choice at which time the third input of the mentioned memory remains blocked.

f) In the case of group selection, the logical "1", the from the signal of the group selection G- is given, the logical "1" of the digits is replaced, whereby these are placed directly in the circle for the logical "or" function SG of the digits (D 130 - D 135) is transferred, where the further process is analogous to the process mentioned under b) to &.).

The logical "1" from the signal G- is also sent to the second input of the memory PG- the group selection (T 120, T 121) transferred, which tips over and it to the beginning a logical "1" on the output G ", similar to the logical" 1 "on the output G when G-ewinn occurs after point e) above, but with an inverse! function of the same.
