(54) DEVICE FOR RECEPTION OF INFORMATION

I

The invention relates to information systems and can be used in discrete communication equipment.

A device for receiving discrete signals having a single-action parallel register II is known.

A disadvantage of this device is low immunity, which reduces the reliability of this information.

The closest to the technical entity to the proposal is a device for receiving information, having in each information channel the first element I, the output of which through the memory block is connected to the information output of the device and to the first input of the comparison unit, the second input of which the first input of the first And are connected to the corresponding information input at the device, the output of the comparison block of each information channel is connected to the corresponding input of the NAND element, the output of which is connected to the "Query" output. recording, the control input of the device is connected to the second inputs of the first elements AND of all information channels 2.

The disadvantage of the device is low noise immunity.

The aim of the invention is to increase the reliability and expand the functionality of the device.

To do this, a delay element and a second AND element are introduced into the device, the first inputs of which are connected to the control input of the device, the output of the delay element is connected to the second input of the second AND element, the output of the AND-NOT element is connected to the third input of the AND element, the output of which is connected to the control device output.

The drawing shows the functional diagram of the device.

The device has information inputs I, information outputs 2, control input 3, output "Request transfer 4, memory blocks 5, AND elements 6, comparison blocks 7, AND-NOT element 8, second And 9 element, delay element 10 and control output II.

The device works as follows.

In the event of occurrence, at the information inputs I of the code combination, which differs from the combination present in the memory blocks 5, the signal "Request for recording information."

After a certain time, the control input 3 of the device receives a signal that opens the first elements AND 6. and the code

the combination is entered into memory blocks 5, while in the channel with the faulty memory cell there is a mismatch of its state with the information value at information input f, and the signal "Information recording request is saved at output 4.

At the three inputs of the element And 9 at the same time there are three signals and they give a fault signal at the output 11. In the absence of faults, there is no fault signal at output 11. In the case of the presence of a delay element Yu at the input of the second element AND 9, the control signal from device 3 is shifted in time by an amount that overlaps the total switching time of the first elements And 6, memory blocks 5, blocks 7 comparison and the element AND-NOT-8.
