The invention relates to computing and can be used in automated control systems to ensure the synchronization of several computers and the possibility of functioning of multi-machine complexes on a single real-time scale in time and. A multi-channel device for synchronization of multi-machine complexes is known, containing in each channel an Emitter-generator, a multi-bit counter and a decoder 111. The disadvantage of this device is its low reliability, since in case of a failure of the master oscillator to synchronize all devices. In addition, the device does not ensure the functioning of all computers in a single real time scale. The closest technical. Essentially, a multichannel device for synchronizing multi-machine complexes that provides multi-machine complexes on a single time scale and contains a master oscillator, a multi-bit counter, a decoder, two OR elements, a trigger, two in each channel. No switch, while the output of the first element OR of each channel is connected to the reset trigger input, the reset input of the multi-bit counter and one of the inputs of the first And element, the second input of which is connected to the zero output of the trigger and the output of the multi-discharge counter is connected to the decoder the inputs of the switch, the output of which connect. It is connected with the input of the second element I, the other input of which is connected to the output of the master oscillator and with the counting input of the multi-bit counter, and the outputs of the first and second elements AND through the second element IL. connected to the output of this channel of the device, the output of the second element of each channel is connected to the inputs of the first elements of OR adjacent channels 12. The disadvantage of the device is complexity. The purpose of the invention is to simplify the device. The goal is achieved by the fact that the device for synchronization of multi-machine complexes containing n tasks for generators (n is the number of channels), n time sensors, two OR elements, two AND elements, two triggers, a counter, a decoder, a switch, and the switch inputs are connected respectively, with the outputs of the decoder, the inputs of which are connected to the outputs of the counter bits, the output of the first element OR is connected to the input of the nth time sensor, the outputs of the time sensors are the device outputs, a group of n elements is entered, mp the delay element, and the outputs of the master oscillators are connected respectively to the first inputs of the elements AND groups, the second inputs of which are connected to the outputs of the switch, the outputs of the elements AND groups, are connected respectively to the inputs of the first OR element, whose output is connected to the inputs from the first through (n-1 a) time sensors, with zero input of the first trigger, with zero input — the second trigger, with the input of the first delay element, the output of which is connected to the single input of the first trigger, with the input of the second delay element, output which is connected to the first input of the first element And, the second input of which is connected to the output of the first trigger, the output of the first element And is connected to the single input of the second trigger, to the first input of the second OR element, the second input of which is connected to the output of the second element And, the first input of which is connected with the output of the second trigger, the second input of the second element AND is connected to the output of the third delay element, the input of which is connected to the output of the second OR element and to the counting input of the counter. The drawing shows the block diagram of the device. The device contains a master oscillator 1, the element And 2, the element OR 3, the element 4 delay, trigger 5, element b delay, element 7, element OR 8, trigger 9, element 10 delay, element 11, counter 12, decoder 13, switch 14, time sensors 15, device outputs 16. The device operates as follows. In the initial state, the counter 12 is in the zero state and at the first output of the decoder 13 there is a single signal, which, depending on the selected priority, via the switch 14 goes to element 2. 2. From the output of the corresponding master oscillator 1, the clock pulses through the input of the element OR 3, and from the output of the latter to the sensors 15, the time of all computers and at the same time to the input of setting the triggers 5 and 9 to the zero state and to the input of the element 4 delay. If the master oscillator, which synchronizes the operation of the computer, functions stably, then the next clock pulse delayed by 0.75 pulse follow-up period goes to the single trigger input 5 and to the input of the delayed element b delayed by another 0.75 pulse follow-up period element And 7, which is closed, since trigger 5 is in the co

that nii

If the master oscillator, which synchronizes the operation of all computers, becomes out of order and the clock pulses of this generator stop, the last pulse of this generator will come from the output of element 4 to the input of trigger 5 and set it to state H, since from the output of the element OR 3 the next impulse trigger 5 does not remain in the state H and the impulse from the output of delay element 6 delayed by 1.5 periods goes through the open element AND 7 to the input of the element OR 8 and to the input of the setting of the trigger 9 to the coC output of the element

standing

OR 8, the pulse will go to the input of the delay element 10 and to the input of the counter 12, setting it to the state. At the second output of the decoder. 13, according to Wits, a single signal, which through the switch 14 arrives at the input of the element AND 2, thereby allowing the arrival of clock pulses from the next second master oscillator 1 to the input of the element OR 3.

If the second connected generator is in good condition, the incoming clock pulse from the output of the OR 3 element will set triggers 5 and 9 to the state O, and the device will function as described above. If the second generator

defective, i.e. the impulse will not come from it during the 1.5 period, then from the output of the delay element 10 the impulse delayed by 1.5 periods will go through the open element

O and 11 to the input of the element OR 8, since the trigger 9 is in the state

From the output of the element OR 8, the pulse arrives at the input of the element 10 of the delay and at the input of the counter 12, increasing its content by one. At the next output of the decoder, according to a Vits, a single signal that connects the next generator for synchronization.

0 If the next generator is faulty, then after 1.5 periods the next generator is connected. Thus, the generators will be connected until a working generator is connected and the pulse from its output through the AND 2 element, the OR 3 element goes to the zero inputs of the flip-flops 5 and 9; . work will continue. Technical and economic effect of

the use of the invention consists in simplifying the technical implementation of the device, as compared with the prototype it has fewer elements and connections. In this case, the proposed device is more adapted to changes in the channel of the device, i.e. satisfies the extensibility property.
