However, in the known devices, if there is information on the controlled point, the duty pulse from the controlled point stops and the light goes out

duty mode. With the help of control keys, the opornos of this controlled point is made to determine the change in the state of objects, fixed by the output signaling elements, which are common to all controlled points. After interrogating this monitored item and translating it again, on duty, information about the state of objects on it is erased, and the output signaling elements are prepared to receive information from other monitored items, which takes a lot of time to manually poll the monitored clause in .15 In order to expand the functionality of the device and increase its speed, triggers, AND elements, registration blocks and OR elements, each of 20 and formation trigger; d the control trigger is connected to the first inputs of the signal elements AND, united by a group of objects, and to the first input of the AND element, whose output is connected to the first input of the call trigger, the second input of the last one is connected to the control output And, and the first output is connected to the first input of the address element I, connected by the second input to the address of the distributor cell, the output of the address element AND is connected to the zero inputs of the control trigger and the registration unit, Information The e inputs of which are connected to the outputs of the signal elements 35 I, the address cell of the distributor of the subsequent information channel is connected to the first input of the control element AND of the previous information channel, the second outputs of the trigger 1 triggers of each information channel 40 of the formation channel are connected to the element I, whose output is connected to the second inputs of the control elements of each information channel, the third inputs of which are connected to (the first output of the 45-unit receiving signals, the second output of the signal receiving unit is connected to the second the inputs of the signal elements AND of each channel, the output of the last cell of the distributor is connected to the second input of the element AND reset 50 of the information channel and the single input of the control trigger of each ipformative channel, the common call cell of the distributor I, the output of which 55 connected to the (First input of the first element OR, the output of the oepiBoro element OR is connected to the second input of the command transmission unit, the output of the addressing elements AND of each information channel is connected60 to The first input of the call trigger of each information channel is connected to the corresponding input of the second OR element, the output of which is connected to the second G5 5321 9 4 input of the All-Calling Element AND, each functional cell of the distributor is connected to the corresponding third inputs of the sieve elements AND of each information channel . The drawing is a diagram of the proposed Dnipropetcher half-set of the device for telecontrol n remote signaling. The dispatching half-set consists of the distributor 1 i.h with the address and working part, the automatic start unit 2, the 3-clock former, the 4th pulse transmission unit, the command transmission unit 5, the control keys 6, the signal receiving unit 7, call triggers 8, And 9 control elements, And 10 element, And 11 adresable elements, And 12 primary calling element, OR 13 first element, second SLI 14 element, PI 16 signaling element registration blocks 16, control trigger 17 and Reset And 18 elements and information channels 19 Dispatch Noluco kits, devices for remote control and remote signaling operates as follows, in the standby mode, each monitored item at the respective work ta-kT pulse distributor 1 enters the standby mode, which is received by signal receiving unit 7. In the presence of a pulse, a 1 appears at the first input of the signal receiving unit 7, and a zero appears at its second output, and zero at the first. In the absence of a pulse, zero appears at the input of the signal receiving unit 7, and zero appears at the second output. In standby mode, when a duty pulse arrives from all monitored points, the call triggers 8 are not activated at the corresponding cycles (the first monitored point corresponds to the second cycle of the distributor 1, the second controlled point - the third., Etc.), since the third the inputs of the control elements AND 9 from the first output of the signal receiving unit 7 are supplied zero. The first inputs of the control elements I 9 receive a pulse at the corresponding clock cycles of the distributor 1, and the second inputs receive a unit of the element 10, the inputs of which are connected to the single outputs of the 8 trigger triggers, the first lody of the address elements M 11 do) T zero from the first outputs of the 8-lz trigger, besides, the same zero signal goes to the second input of the All-call element AND 12 through the second element OR 14, therefore the outputs of the address element And 11 and the general-call element And 12 through the first element OR 13 for the corresponding measure Job distributor 1 do not affect the second input unit 5 send commands. As a result of this call, the controlled points do not occur, they do not receive signals about the status of objects, and information about the state of objects 5 at the controlled points is not received in blocks 15 of the registration. If at any controlled point, for example, at the first, there is a "change in the state of the objects, then at the second cycle of the distributor 1, corresponding to 5 for this controlled point, on the zhoa.e of the signal receiving unit 7 there is no imp.:. mode, at its first output, a unit arrives at the third 10 inputs of control elements AND 9, the second inputs of which receive a unit from AND 10, since all call triggers 8 are in their original, reset state} 1. At the same second cycle, a single pulse 15 from the second cell of the distributor 1 is delivered to the first input of the control element AND 9 of the first channel. The latter is triggered and cocks the first call trigger 8, with the result that zero is received from the first call trigger 820 and 10 arrives at its output, zero also appears at its output, and the input of call triggers 8 is disabled at the second inputs of the control elements 9. Thus, if on the following so-25 max there are no duty pulses, and the first output of the signal receiving unit 7 is 1, then the call triggers 8 are not activated, which prevents simultaneous calling of several controllable 30 points. The first trigger 8 calls on the first input of the first address element And 11 and through the second element OR 14 to the second input of the All-Calling Element And 12 prepares them to trigger. In the general call cycle of the distributor, 1 pulse from the common call cell arrives at the first input of the general call element AND 12, which triggers through the first element OR 13,40 the general call pulse arrives at the second input of the command transmission unit 5, sending a general call pulse to the communication line. However, none of the controlled points is put into operation, since in the link there is no impulse of the controlled point number. At the working time of the working part of the distributor 1, the signal from the communication line to the input of the signal receiving unit 7 does not receive the signaling alarms, and zero appears at its second output, therefore the signal elements AND 16 do not work, and the information on the state of the objects in the registration blocks 15 not recorded. In addition, the triggering of the signal elements 55 AND 16 is prohibited by the zero outputs of the control triggers 17, which are recovered from the corresponding address elements 11. At the last work cycle, distribute -60 l 1 a pulse arrives at the input of the synchromesh transmission unit 4 and the reset of the triggers 17 controls that are in the reset state. The same pulse arrives at the second inputs of the elements And 18 reset, through 65 6 which reset the triggers 8 call. But the elements AND 18 of the reset does not work, so, as their operation is prohibited on their first input by the corresponding control triggers 17. The first trigger 8 of the call remains cocked and continues to enable the first input of the first address element AND 11 and the second element OR 14 of the general call element AND 12 to trigger. In the next cycle "in the first clock cycle of the distributor 1, the output of the first cell sends a pulse to the second input of the first address element 11, which is triggered and through the first element OR 13 acts on the second input of the command transmission unit 5, sending to the communication line the "pulse number of the first controlled point, the same pulse from the output of the first address The common element AND 11 resets the first registration unit 15, preparing it to receive new information about the state of the objects at the first controlled point and cocks the first control trigger 17, preparing the first input element 18 for resetting the alarm elements AND 16 the first channel. On the remaining cycles of the address part of the distributor 1, the pulses of the number of other controlled points are not received in the communication line, since the other address elements AND 11 are not prepared for triggering by the corresponding call triggers 8, On the general call cycle of the distributor 1, the general call element And 12 and through the first element OR 13 acts on the second input of the command transmission unit 5, which sends a general call pulse to the communication line. Thus, a pulse train consisting of a pulse of the number of the first Controlled Point and a General Call Pulse enters the communication line and puts the first controlled point into an operating mode, which allows the transmission of an object state signal control point to controlled item. At the working hours of the working part of the distributor 1, information pulses are received from the first controlled point to the input of the signal receiving unit 7, acting through its second output on the second inputs of the signal elements I 16, the third inputs of which receive pulses from the corresponding functional cells of the distributor 1, resulting in . the corresponding signal elements AND 16 of the first channel are processed and. send signals to the first channel registration unit 15. The signal elements AND 16 of the other channels do not work, since they are not prepared for activation by the corresponding control triggers 17.
