Description

The invention relates to computing technology 5 or, more precisely, to a device for transferring digital data to a computer using a sampling of analog values at regular intervals of time.

The purpose of the invention is to improve the accuracy of the increase in speed.

The drawing shows a diagram of the proposed device.

The device for generating time stamps contains a generator 1 pulse-from Z5, the first divider 2 frequencies, the per-key 3, the first block 4 of keys, the register 5 of memory, the second block 6 of keys, the first counter of 7 pulses, first, 8 and the second 9 the triggers, the first element OR 10 is the first II, the second 12 / rety 13s the fourth 14 and the installation 15 inputs, the first 16 and the second 17 outputs 5 the second key 18, the second divider 19 frequency 5 the third switch 20, the second 21 counts pulse third Christmas tree 22 keys and the second element

ty 23,

The device works as follows

In the initial state, the keys 3, 18 (20 are closed, the triggers 8 and 9 are in the initial state5, i.e. there are no signals on the outputs 1.6 and 17 of the device, counters 7 and 21 are inactive. To start the device on its mouth - The input time code is supplied to the input terminals 15. Then, during the time the signal is active, input 4 of the device also receives a pulse 4 key block opens and the time interval code goes to register b, where it is stored, and correspondingly to information inputs 5 blocks b to 22 keys . Simultaneously, the impulse from the device. 14 code through this The PN 10 enters the control input of the key block 6 and the time interval code - the AI is entered into the counter 7. Then a pulse is sent to the input 12 of the device, a stable opening key 3, and pulses through the generator I, divider 3 and key G 3 is sent to the counting input of the counter 7. At the same time, the impulse from the start 2 of the device blocks the key 8 and overturns the trigger 8 into the initial state or confirms this state and also, passing through the 55 element OR 23, opens the key block 22, providing receipt of a code of a time interval in the counter 21 with

Register 5 through a block of 22 keys. In this case, the signal at the output of the overflow of the counter 21 disappears and the key 18 is blocked. As the pulses arrive at the counting input of counter 7, the latter overflows the J overflow signal from its output through the element OR 10 opens block 6 of keys and again transfers the code of the time interval from register 5 through block 6 of keys to counter 7 and the cycle repeats. At the same time, before the disappearance of the signal from the output of the counter 7, the trigger 8 overturns, and the second signal appears on its second output.

time, arriving at the first output 16 of the device, and at its first output a resolution signal appears, arriving at the keys 18 and 20 and passing through the HLR element 23, which ensures the transfer of the time interval code from the register 5 through the key block 22 to the counter 21 filling the counter 21 in the absence of computational responses: the device on the Timestamp it overflows, and the signal from its output goes through the key 18 to the trigger 9 and overturns it, causing the appearance of the signal Error. at the second exit, I 7 device. The computing complex responds to this signal and starts working on the emergency branch of the program. In this case, the input device 13

a signal is given that returns trigger 9 to the initial state and the error signal at the output 17 of the device disappears. The device 12 also signals the reset trigger 8 to the initial state, the counter 21 stops counting pulses, and the source code of the time interval is entered again, and so on. With the timely response of the computing complex to the time stamp at the output 16 of the device, the signal from the computing complex is fed only to the input 12.

Termination of the device operation is provided by applying a signal to the device input 1I. In this case, the key 3 stably closes and the counter 7 stops counting the pulses.

The use of the invention allows to increase the accuracy and increase the speed, exclude the occurrence of emergency situations during the operation of the computing complex, due to

which reduces the loss of its useful time.
