The task of high-speed transmission can be ensured, as is well known, by transmitting two lines of information that make up the signal, not 1 base, but in time, but simultaneously along different channels. L, .1 this is required

It is provided by the arrival of signals consisting of each group of impulses, representing the unit packages transmitted over the channels.

To ensure that the order is received without distortion and the elimination of false orders, it is transmitted in the form of a signal consisting of several pulses that are independently recorded at the receiving point. The smallest possible number of pulses in a signal are two pulses.

In order to ensure failure-free transfer of an order, it is transmitted by several independent signals sent via different channels. The smallest possible number of signals transmitting a single order are two signals.

To ensure a short transmission time, all pulses constituting one order (several signals) are transmitted simultaneously on different channels.

FIG. 1 shows the transfer of orders given simultaneously by two signals, each of which is composed of two pulses; in fig. 2 shows the transfer of two such orders; FIG. 3 illustrates the essence of the invention — signal transmission over two channels with pulses shifted in time; FIG. 4 - receiving at the receiving station collection signal.

FIG. Figure 1 shows the known method of transmitting an order, executed by two signals consisting of one — of pulses a and b, transmitted over two channels, and the second — of pulses a and b, transmitted over two other channels. Thus, the simultaneous transmission of orders over multiple channels causes an increase in the number of channels by as many times as the multiplicity of orders to prevent failure.

If it is necessary to transmit more orders, it is necessary to further increase the number of pulses so that each of the signals of one assignment corresponds to its own, only a combination of pulses is inherent in it, as shown in FIG. 2, regarding the transfer of the order / signals made up of impulses a and b and, respectively, a and b, and order I - signals made up of impulses ai (and, respectively, a and 6.

With the proposed method of remote control, shown in FIG. 3, in each signal transmitted by a combination of pulses, these pulses are shifted in time by an amount At sufficient to trigger an electromagnetic, magnetic, electronic, or any other relay. As can be seen from FIG. 3, in this case, the transmission of a signal by even two pulses makes it possible to obtain at least two combinations and, obviously, a greater number of combinations can be obtained if pulses of different lengths are used.

Thus, due to a slight increase in the transmission time due to a pulse shift in time, it is possible to increase the number of possible combinations and reduce the number of communication channels.

The simultaneous transmission of signals from different points allows you to receive at the receiving point a collective order acting on the descrambler. FIG. 4 shows the sending of two transmitting points L and 5 signals, the composition of the liens of the impulses aa and bb, forming collective orders / and /.

As channels of communication, channels of any purpose can be used — communication, telemetry, telecontrol, tele-dialing, telephony and protection.
