Description

The device consists of a block I selection of primary information containing sensors and primary transducers. The outputs of block 1 are connected to the inputs of accumulators 2о, ..., 2n-i and information intended for accumulating discrete information and issuing a signal in scaled form, the outputs of which are connected to one of the inputs of amplifiers Zo, ..., by their inputs connected to Inverter inputs 4o. - .., ni, designed to implement the logical function "negation, and to one of the inputs of the And 5o, ..., 5i-i circuits, allowing to generate a device start signal for transmission at a certain moment through only one of the circuits and only at the idleness of the device by transmitting information that arrived at a different price earlier, for which the outputs of all inverters 4о, ..., 4п-л except the inverter of its circuit, as well as the outputs of the switching unit 6 of the communication equipment intended for switching the communication equipment, are connected to the remaining inputs zi from the mode "reception in the mode m "transmission, and vice versa. The inputs of block 6 are connected to the outputs of all AND 5o, .-, schemes, and one of the outputs of block 6 is connected to the inputs of all And 5o, ..-, 5p-i schemes to impose a ban on signal transmission when the communications equipment is in mode "transfer. In addition, the outputs of all circuits And 5o, ..., 5n-i are connected to the inputs of the encoding and input unit 7 connected to the input of the communication channel 8, to the second input of which another output of the unit 6 is connected. Channel 8 is connected with its own output and the input is connected to the input and output of the control room 9, where the transmitted information is recorded. The second output of the communication channel 8 is connected to the input of the election and deciphering unit 10, where response messages are generated about the reception of information on certain parameters from zero to (n-1) -th. The outputs of the block 10 is connected to one of the inputs of the block 11 of the control transmission and reception of information. The block 41 is intended for storing signals that characterize the operation of the object being monitored and arriving from information storage devices during the device occupancy period by sending information packages, as well as for storing signals while simultaneously receiving them from information storage devices, for launching the device for transmitting information signals on each of the parameters memorized by triggers 12о, ..., 12п-ь for the retransmission of the information signal in the absence of a response message from the control point p about the passed parameter; for transferring the device to transmitting an information signal on a different parameter in multiple retransmissions and information signal on the previous parameter and to indicate an alarm condition. The block 11 includes memory triggers 12o, ..., 12n-i, to the zero inputs of which are connected respectively the outputs of the block 10, to the single inputs of which and to the inputs of the node 13 of the formation of control pulses are connected the outputs of the amplifiers Zo. ..., Zp-1 Exit of triggers 12o,. . ., connected to the inputs of the circuits And 14o,. . ., 14ri-i directly and through amplifiers-inverters 15o ... circuits And 14i, 142, ..., 14n-i, i.e., apart from its circuit 14o, and the output of the trigger 12i is connected via an amplifier-inverter 15i to the inputs of the circuits And 142, 14z, ..., 14, ii, t that is, besides its own and previous In order number circuit And, and, finally, the output of the trigger through the amplifier-inverter is connected to the input circuit And 14n-1The remaining inputs of all circuits And connected to node 13, and the outputs of these circuits AND are associated respectively with the other inputs of amplifiers Zo, ..., Zi-i. In the initial state, the triggers 12o, ... are in the zero state, and block 6 supports the communication equipment in the “receive” mode. When the engine of a moving object is turned on and entered into the dynamic mode from the primary information selection block 1, continuous signals, converted into a discrete form, are fed to the 2o, .., 2n-1 data storage devices. At intervals equal to the duration of filling the 2nd, ..., 2n-i accumulators with information about the object's parameters, pulses are output from their outputs, which characterize a fixed parameter value, which are sent to the corresponding amplifiers. 2c information is fed to the amplifier Zo, after amplification, a 5 ° coincidence circuit is fed in and to a 4o inverter, the output of which imposes a ban on all AND 5i, ... circuits, except the And 5o circuit. In addition, the signal from the output of the amplifier Zo goes to the "single input of the memory trigger 12o, sets it to the" single state, and pa input to the node 13 of the formation of control pulses. The signal from the output of the AND 5o coincidence circuit is fed to the input of the switching unit 6 of the communications equipment, including its transmission, to the input of the coding and input unit 7. In this case, two pulses are output to channel 8 from block 7, modulated by the corresponding tonal frequencies in

depending on which chain the information signal comes to the communication channel. These pulses in block 7 are generated as follows: when a signal arrives from a corresponding circuit, transmitting information about a specific parameter, a push-pull pulse distributor is started, which, through the corresponding key circuits, switches each of the two tone frequency generators in succession. With the help of block 6, the permission is received by the reception of communication channel 8 from block 7 and the subsequent transmission of the information parcel to the dispatch station 9.

After receiving this information parcel, the dispatch center issues a reply package. In this case, there are two possible ways for the device to operate: when receiving a response parcel (see FIG. 2) and in the absence of receiving a response parcel (see FIG. 3). In the case of receiving a response parcel, it is deciphered by the electing and deciphering unit 10, and from its output a signal is set that sets the memory trigger 12o to zero, thereby indicating that the information parcel for this parameter is received by control station 9.

The same thing happens if a signal is issued according to the following parameter from another storage device, for example, from storage device 2n-1. In this case, the signal, after forming by the amplifier Zp-i, is similar to the amplifier Zo, sets its trigger memory 12p-1 into one state, enters the input of the 5n-i circuit and, through the inverter 4n-i, prohibits all I 5o, .. ., 5п-2, besides its own circuit, and from the circuit 5n-i is fed to the inputs of blocks 6 and 7 and further similarly via channel 8 of communication to the control room 9. If this information message is received by the control room, then a signal is output from which, after being decrypted by block 10, enters the “zero input of the memory trigger, sets it to “The zero state and confirming that the information parcel is received by this parameter and it is possible to transmit information to the next parameter.

The transmission signal is generated by the control pulse generation unit 13 or by the signal from the 2 o accumulators,. . ., information through amplifiers Zo,. . ., Зп-ь and the order of issuing information about the parameters is determined by the schemes "And 14о,. . ., due to the fact that in block 11, the outputs of each of the 12 o flip-flops,. . ., connected to the corresponding inputs of the circuits And 14b. . , 14n-i through inverters 15o, ..., prohibiting the issuance of information on those parameters whose sequence number is greater than the parameter number of the parameter that is currently being transmitted.

Thus, setting the “zero” of the memory trigger 12o allows obtaining a resolution for transmitting a signal about the second parameter from the AND circuit.

14, and setting zero to trigger 12 permits the transmission of a signal about the third parameter of the AND 142 circuit, etc., but despite this, receiving a signal from storage device 2o allows the device to turn on the transmission of information about the first parameter, and then go to performing an interrupted sequence.

where pic is the time equal to the duration of the information package; pauses - waiting time for a return message from the control room; pr is the time of the response send time, the response send will not follow and block 10 does not generate a signal for setting the memory elements to zero, for example, a 12l trigger, the control generation unit 13

pulse generates a signal to restart the device in the transmission mode, which through the circuit 14, - i (since the trigger 12p-1 is in the "one state") enters the input of the amplifier Zl- and starts the device to retransmit information about this parameter.
