Description

information through the EL-4 element into block 2. Channels K 8, -8 ,, with the same name from T 7, -7 are opened, and through that, on the 1st input to-ry, the signal of the switched on code channel from the control input (HC ) devices, the corresponding channel of block 1t is turned on. The delay time in block 9 is equal to the duration of ne

The invention relates to the technology of the transmission of discrete messages and can be used in trajectory measurement systems (STI), mainly in the radio engineering symmetry of near navigation (RSBN) dp information transmission.

The purpose of the invention is to increase the amount of information transmitted.

The drawing shows the structure of the electrical circuit of the device.

A device for transmitting information contains a code 1 block, a block 2 for entering and storing information, the first and second elements OR 3, 4, the AND elements, the main and additional synchronizers, triggers 7, -7 | switches, block 9 delay.

The device works as follows.

: In the initial state, one of the control inputs of the device and through it the corresponding first inputs of the switches 8, -8 receive the signal of the number of the working channel from the code channel switch of the onboard equipment STI (RSBN) o At the corresponding time instances synchronizers turn on starting impulses transfer of the same information sources. The total control of synchronizers 6 (-6) j, which ensures the mismatch in time of the waveforms that carry information from different onboard sources, is carried out by signals from the ground station STI (MSBN) via a common timer of the onboard equipment STI (not shown) about the trigger pulses of the synchronizers through the first the element OR 3 is fed to the starting input of coding block 1, one-time

rendered codograms. Due to the non-repeating connection of 1 channel inputs K 8, -8j, to V B of the device, the signal of the code channel number changes on the HC of block 1, and the transmission of information from the other source of information will go to another code channel. 1 il.

The If - 7ts trigger with the same name as the source of information is switched on, the output of which opens the corresponding element AND 5, -5jjj, allowing the input of information from the corresponding information source through the second element OR 4 into the information input and storage unit 2. Parallel to the signal from the output of the included corresponding trigger 7-7 / y, the second inputs open with the same names with the trigger 7 | The -7fj channels of all the switches, and through the one at the first input of which the signal of the included code channel STI (RSBN) from the control input of the device goes, includes the corresponding code channel of the coding unit 1.

The information entered into block 2 is coded (recorded in block 1 and passed through its information output to the transmitter.) After the codogram is transmitted, the included trigger 7 returns to zero (7c and the device returns to its original state. Delay time block 9 equals; h; the length of the transmitted codograms.

After the next following sync signal from another synchronizer 6 | -6), the process is repeated, but information is already entered from another source of information through the corresponding element 5 (-5 (. In addition, due to the non-repeating connection of the first channel inputs of switches 8, -8ts | to the control inputs of the device at the control inputs of the coding unit 1 will change the control signal of the code channel number and the transmission of information from another information source will go to another code channel.
