Description

The invention relates to telemechanics and can be used to transmit discrete information. The purpose of the invention is to increase the speed and information content of the device. The drawing shows the functional diagram of the device. The device contains an input 1, a distributor 2, a counter 3, a driver 4 commands, a switch 5, a multiplexer 6, a driver 7 control signals, blocks 8 sensors of the forest alarm-telemeasurement, shift register 9, elements 10, the element OR NOT 11, the element IC1E 12, outputs I 3 and 14. The device works as follows. When the clock pulses arrive at the input 1, the distributor 2, connected in a ring circuit, forms n + 1 pulses, each with a duration of m ticks C (n + 1), the pulse is cut through with ticks. In this connection, the duration of the transmission cycle is equal to mv (n +) cycles. Last beat at. the transmission cycle is used as a marker parcel and is output to the output 14 of the device. To read TCITI information, the device from the clock sequence from input 1 generates a transformer 4 and switch 5 with a pulse sequence of щ clock cycles for each block 8. At each clock cycle, block 8 provides information about the state of one of the m TC sensors or the value of one of m bits Dov digital code TI. Thus, the device operates cyclically, during a single transmission cycle, the output 13 of the device generates a series of pulse code signals per m TC sensors and m times 572 rows of TI o, n n blocks 8 (and is the number of blocks 8 serviced in one transmission cycle). In the subsequent cycles, information from the remaining blocks 8 is read, the maximum number of which can be 2, where k is the width of counter 3, which counts the transmission cycles and generates the loop address in the driver 4. The logical combination of the n and k signals in the driver 4 determines the program read information from the blocks 8. The frequency of the signals (control commands) of this program, satisfying the specified criterion, is dialed in the shaper 4 out of 1,2 ... n impulses of the distributor 2 and k information outputs of the counter 3. For example p, one of the groups of TC sensors allows a lower sampling rate. By combining in the shaper 4 the least significant bit of the counter 3 with the corresponding pulse of the shaper 2 the selected block 8 will be serviced only in odd transmission cycles. In this case, even transmission cycles can be used to service an additional block 8. Thus, the device can serve more than n blocks 8 of the same duration of the transmission cycle. At the command of the driver 4, the switch 5 skips n cycles to the input of the corresponding block 8, and the corresponding element AND IO and the element OR-NOT 1I connect the output of this block to the output 13 of the device. When the pulse information passes to the input 13 by the register 9, the driver 7 and the multiplexer 6, control signals are generated which, together with the address of the transmission cycle at the (n + 1) -th position of the distributor 2, are transmitted to the output 13 of the device.
