Abstract

THE AUTOMATIC METHOD OF THE SUBSCRIBER SIGNAL PACKAGE, consisting of the S transmission from each subscriber of packets of signals consisting of each of the information signals, as well as the priority signal, the address signal of the recipient subscriber and the address signal of the subscriber sender, followed by storing the specified signal packets in groups according to priority signals in order to form them, with the first one transmitting a signal packet c. by receiving the highest priority signal, and when receiving the subscriber’s address signal, the received batch of signals is compared with the subscriber’s own address signal and if they match, the received signal of the forwarding signals to the subscriber is different in that; in order to reduce the signal selection time, when receiving a subscriber’s own address signal with the received signal of the receiving subscriber, the received signal compares the priority signals of the received signal with the priority signals of the previously stored signal packets with the highest priority. That packet of signals above Prio & the received packet of signals is transmitted to the next subscriber with the priorities of previously stored signal packets, and if the priority signal is not exceeded, the received packet of signals is remembered by the last packet in the group with the corresponding priority signals, and the packet of highest priority among the subscriber is transmitted: l number previously stored signal packets. about: 00 joint venture

Description

The invention relates to radio engineering and can be used in the transmission of discrete signals over communication channels of information computing and telemetry systems.

There is a known method of automatic selection of subscriber signal packets for transmission over communication channels of an information network, concluding that each subscriber forms a packet of signals consisting of information signals, a reception signal, a recipient address signal and a sender address signal, and transmit them on the node xmmutation. At the switching points of the communication channels, they store the received signal packets and S correspondence; with signals of their priorities, are transmitted to other switching nodes l. .

The disadvantage of this method is the relatively large time selection packet signal subscriber.

The closest to the proposed method is the auto selection of subscriber signal packets, which consists in transmitting from each subscriber a packet of signals, each consisting of information signals, as well as a priority signal, the destination signal of the recipient subscriber, and the subsequent signal of the specified subscriber. packets of signals in groups in accordance with the priority signals in the order of their formation, with the first transmit a packet of signals with the signal of Higher Priority, when receiving the address signal The recipient of the received signal is compared with the subscriber’s own address signal, if they match, the received signal is transmitted to the subscriber 2J.

However, according to a known method, due to the uneven service of each packet of signals in the same priority group, the time for selecting a packet of signals from each subsequent subscriber connected to the common information highway of the communication system increases.

The purpose of the invention is to reduce the time of selecting a packet of signals when transmitting along a common information highway.

This goal is achieved by the fact that, according to the method of auto selection of a subscriber signal packet, consisting in transmitting from each subscriber a packet of signals consisting of each information signal as well as a priority signal, the address signal of the recipient subscriber

and a forwarding subscriber's signal, followed by storing the indicated signal packets in groups in accordance with the priority signals in order of their formation, with the first signal packet transmitted with the highest priority signal, when receiving the received signal packet subscriber of the received signal packet compare0 with their own address signal of the subscriber;

5 signals of the subscriber with the address signal of the subscriber-recipient of the received signal batch compare the priority signals of the received signal packet with the priority signals of the previously stored signal packets with the highest priority and when the priority of the received signal signal exceeds the priority of the previously stored signal packets the received packet signals are transmitted to the next subscriber, and if the priority signal is not exceeded, the received signal packet remembers the received signal packet later in the Group with its corresponding ignoring priorities, and transmitting to the next subscriber a packet of signals with the highest priority from among the previously stored packets

FIG. 1 shows the structural electrical circuit of the information transmission system, which implements the proposed method; in fig. 2 - variation of the subscriber unit execution unit. The information transfer system (Fig. 1), which implements the proposed method, contains the input line of the information highway 1, the receiver

c 2, shift register 3, switches 4 and 5, element OR b, transmitter 7, information line output line 8, gate driver 9, keys 10 and 11, block 12 of the comparison of address signals, block 13.

 comparison of priority signals, element 14, element 15, keys 16 and 17, controlled switch 18, priority signal encoder 19, buffer blocks 20; j, 20, ...

Vlok 22 of the subscriber (Fig. 2) contains the register-generator 23, the receiving buffer memory block 4, the sender address register 25, the recipient address register 26, the data register 27 and the priority register 28. The information transmission system works as follows.

In the subscriber block 22 (FIG. 2), the signals from the sender's address, the recipient's address and the priority signal in the respective registers 25-28, form a signal packet in the register-former 23. Under the action of the priority signal received at the first control input of the controlled switch 21 (Fig. 1), the signal packet is stored in the buffer blocks of the memory (the FBT number corresponds to the priority signal number).

The incoming signal packet from the input line of the information line 1 is received at receiver 2, the signal of the recipient's address and the priority signal are stored in shift register 3. Upon arrival of a packet of signals, the driver of the 9 strobe gaps for gates equal in duration to the transmission time of the address signal and the priority signal. At these time intervals, the address signal of the incoming signal packet through the key 10 enters the address comparison block 12, which also receives the subscriber’s own address signal (from the sender’s address register 25). When the address signals match, the switch 4 switches to position 2 and the input to the VDI signal packet enters the receiving buffer memory unit 24 in the subscriber unit 22. If not matched, then in the transmission interval of the priority signal of block 13, comparison of the near ground signals, the highest priority signal, which comes from the priority encoder 19,

the signal that determines the highest priority signal from the priority signals of the signal packets stored in the BBP 20o - 20z, and at. a priority signal

the signal packet through key 11. If the incoming signal of the incoming signal packet is smaller, then

at the output of the element And 14 will be one logical signal, which

0 will switch switch 5 to position 2.

In addition, the key 17 under the action of the same signal will miss the priority signal of the incoming packet

5 signals for switching the controlled switch 21 on the second control input to the corresponding BBP 20-20,: in this case the incoming signal packet through

0 switches 4 and 5, the second information input of the controlled switch 21 will go to the corresponding BBP 20 - 20 (4. At the same time, under the action of a single logical signal from AND 14, the key 16 will open and the highest priority signal will go to the controlled switch 18 from the encoder 19, the prior "signal, under the action of which the control 18 switches through the element OR 6 and the transmitter 7 to the output line of the information trunk 8, that of BB.P

e 20 ((- 20 ,. in which the burst of signals with the highest priority is currently stored.

The method provides a reduction in the time it takes to select a packet of signals when transmitting along a common information highway.
