A disadvantage of the known device is low speed, since the signal enabling polling; A corresponding source of information appears at the output of the devices only after the interrogation pulse signal circulating around the ring arrives at the switch corresponding to this channel. The aim of the invention is to increase speed. This goal is achieved by the fact that a multichannel device for controlling the sequence of processing requests, containing channels, and in each, cmc channel, three triggers and the first element I, and the single input of the first trigger is connected to the corresponding request input of the first trigger connected to the corresponding output of the device, to the forward output of the second trigger and to the information input of the third trigger of its channel; the output of the first trigger is connected to the first input of the first element And its channel, which input is connected to the inverse output of the third trigger, direct output, the third trigger is connected to the zero input of the second trigger of its channel, which synchronizes the inputs of the third trigger of all channels connected to the polling input of the device, three AND elements are introduced, two OR elements, IPI-NE element and the trigger, and in each channel - the second element AND, in all channels except the first and last, elements OR, NOT and YNI-NOT, in the last channel - elements NOT and ILY-NOT, while the device's polling input is connected to the first input first element OR you the stroke of which is connected to a single trigger input, the output of which is connected to the first input of the first element And, the zero input of the trigger is connected to the output of the first element And to the first inputs of the second element And of all channels, the second input of the first element And is connected to the input of clock and pulse devices and to the first input of the second element I, the second input of which is connected to the first input of the third element I and with the output of the element S1I-NO, the output of the second element I connected to the zero inputs of the third flip-flops of all channels, the request inputs of the devices va is connected to the inputs of the second element OR, the output of which is connected to the second input of the third element AND whose output is connected to the second input of the first element OR, the outputs of the first elements AND channels are connected to the inputs of the element OR NOT, the output of the first element AND of the first channel is connected to the second the input of the second element AND its channel and to the first inputs of the elements OR and OR-NOT the second channel, the output of the first element AND the second channel is connected to the vtorz1m input of the element OR its channel the latter is connected to the first E1 input of the element OR NOT of the following. channel outputs of the first elements And channels, except the first. through the elements flE of their channels are connected to the second inputs of the elements OR NOT their channels. The drawing shows a functional diagram of the proposed device. The multichannel device for controlling the order of processing requests contains a trigger 1, elements SHSh 2 and 3, elements AND 4-6, element OR-NOT 7, and in each channel triggers 8-10, element AND 11, element OR 12, element 13, the OR-NO 14 element and the AND 15 element, the device's request inputs 16, the device outputs 17, the device polling input 18, and the device 19 clock pulses input. The device works as follows. In the case when each consecutive application arrives at the corresponding input after completing the service of the previous application, the impulse request signal arriving at the input 16 (for example, the first channel) of the device switches the corresponding trigger 8 to one. At the output of the trigger 8 a high potential level is formed, as a result, the element 11 turns off and at its output a low level of potential changes to a high level of potential from the output of the element 11 and opens the element 1 and through the element OR-NOT 7 the elements AND A and 5. But before the element 4 and 4 is closed, its second input from the request input 16 through the element OR 3 will receive a pulse request signal, which passed the element 4 and the element OR 2

Trigger 1 is turned on in the single state. At the output of the latter, a high potential level is formed, as a result, element 6 opens and another clock pulse from input 19 sets trigger state 1 to zero state and trigger element 9 through open element I 15. As a result, at the output of the trigger 1 - a low potential, which closes the element And 6, and at the output of the trigger 9 - a high potential. From the output of the flip-flop 9, the signal goes to the corresponding output 17 of the device and the zero input of the flip-flop 8, which switches to zero at this signal. The signal from output 17 enables polling corresponding.

the prohibition (blocking) of the transmission of readiness signals for servicing information sources through elements 11. The device is ready to service the next requests.

In the case of simultaneous requests for its inputs, all the corresponding triggers 8 are switched to one state. On

The 0 output of all the corresponding AND 11 elements is a positive signal (ready signal), but only one AND 15 element is open, namely that channel,

5 which has the smallest number in comparison with those channels to which requests came. When this happens, the maintenance of the relevant source of information, in this case the first. The end of the survey of the specified channel occurs when a control pulse arrives at the input 18 of the device. This impulse arrives at the synchronization inputs of the flip-flops 10 and through the element OR 2 to the unit input of the flip-flop 1. In addition, this impulse arrives simultaneously with the clock pulse acting on the input 19 of the device. The control pulse with its trailing edge switches the trigger 10 of the first channel to one state, since at that time a positive signal acts on its information input from the output of the corresponding trigger 9. A high potential level is formed at the direct output of trigger 10, and a low potential level is formed at its inverse output, as a result, trigger 9 is reset to zero, and the passage of a positive signal (signal of service readiness of the corresponding subscriber) through element 11 is prohibited. A signal from the output 17 of the first channel, enabling interrogation of the corresponding source of information, is removed. After the appearance of a low potential at the output of the element 11 of the first channel, the element 15 closes and the next clock pulse from the input 19 of the device does not pass to the output of the element 15. At the same time, a positive potential appears at the output of the element OR-NOT 7 4 and 5 are opened, and the clock pulse from input 19 brings all triggers 10 to the zero state, as a result of which the source of information is removed in the same way as the one described. Upon completion of the service of this request, the trigger 10 of the corresponding channel is triggered. As a result, the latter, using the corresponding element I 11, blocks the readiness of this channel until the service of all requests from other subscribers is completed and the element 5 is opened. Element And 15 of the next channel. The device performs maintenance of the relevant source of information, etc. At the end of the service of the last source of information, similarly to that described, the locks are released (the trigger 10 is transferred to the zero state). The application of the invention allows to increase the speed of the device.
