Description

The invention relates to electrical measuring equipment and can be used in automated control systems.

The aim of the invention is to increase speed by reducing the processing of each pulse in a separate channel and extending the functionality by defining any given part of the pulse.

The drawing shows a structural electrical circuit device.

The device consists of n channels 1-1, 1-2, ..., 1-p, each of which contains the main inputs 2-1, 2-2, .. ,,, 2-p, additional inputs 3-1, 3-2, o .., 3-p, main outputs 4-1, 4-2 ,, ,,., 4-p, additional outputs 5-1, 5-2, o .., 5-p, first 6 and the second 7 elements OR, the first 8, the second 9 and the third 10 keys, the driver 11, the reversible counter 12, the inverter 13 and the second delay line 14, as well as the first delay line 15 and the first 16 and second 17 oscillating pulse generators, , the output of the element OR 6 is connected to the control input of the key B, the first signal output of which is connected to the control input of the key 9 and the second input of the imaging device 11, the first input of which is connected to the second input of the element OR 6, the second input of which is connected to the second output of the key 8 and the auxiliary output of the channel, the first input of the imaging device 11 is connected to the first input of the element OR 7 and the output of the reversing counter 12, the summing input of which is connected to the output of the key 9, and the subtracting input through the inverter 13 and the second delay line 14 to the output of the key 10, the control input of which is connected to the second output of the imaging device 11, the third input of which connected to the output line 15 of the delay, the input of which is connected to the input of the device and the input of the key 8, and the outputs of the generators 16 and 17 are connected respectively to the inputs of the keys 9 and 10.

The device works as follows.

The controlled pulse enters the main input 2-1 of the first channel 1-1 and through the normally closed output of the key 8 to the control input of the switch 9, switching it to the closed position. Filling pulses of the frequency F from the generator 16 through the key 9 are fed to the summing input of the counter 12. Upon completion of the monitored pulse, the key 9 returns to its initial state and disconnects the generator 16 from the summing input of the counter 12. At the same time, the driver 11 outputs the signal to the key 8j which disconnects the channel 1-1 from the subsequent input pulses, connecting the input 2-1 to the main input of the next channel, With the arrival of the input pulse delayed on the delay line 15, the driver 11 switches The key 10 to the closed position allows the passage of filling pulses from the generator 17 with the frequency KF to the subtraction input of the counter 12 through the delay inverter 13 and 14.

m - the minimum required 0 number of bits of the counter; n - minimum. required number of channels. Since the delay tj is always less than t „c, after switching the key 10 to the closed position, the counting pulses can be simultaneously applied to the summing and calculating inputs. In order to exclude incorrect operation, the inverter 13 and the delay line 14 serve in the circuit, the delay time of which must be longer than the counter response time. As a result of the summation and subtraction of the pulses, the counter is nullified and a pulse, which indicates the determination of a predetermined part of the input pulse, is detected. The pulse from the output of the counter 12 through the driver 11 returns the key 10 to the initial state, disconnecting the generator 17 from the subtracting counter of the counter 12. From the other output of the driver 11, through the WL 6 element, the key 8 receives a control signal that returns it to the initial state. Channel 1-1 is free from processing the first monitored pulse and is ready to process subsequent pulses. However, if at this moment the next monitored impulse passes through the normally open output of key 8, then THIS impulse through the OR 6 element maintains the control signal on key 8 and until the end of the monitored impulse does not open the previous channel that is not processed, preventing false alarms. The impulse from the output of the counter through the element OR 7 is fed to the main output of the device. On the element OR 7, the output pulses are combined with the pulses coming from the subsequent channels.
