(54) DEVICE FOR CORRECTION OF ACCOUNT ERROR

one

The invention relates to the field of computing technology and, in particular, to devices for correcting the counting error.

A correction device comprising a trigger, keys, a main counter, inverse outputs of which are connected to signal inputs of transfer keys, outputs of which are connected to inputs of an additional counter, outputs of which are connected to inputs of a decoder, control inputs of transfer keys are connected to the first input of the device, and the counting input of the additional counter is connected to the second input of the device.

The purpose of the invention is to reduce the equipment of the device.

This is achieved by connecting the output of the decoder to the polling key control input, the output of which is connected to the trigger input, the output of which is connected to the control inputs of the input key and the blanking key, the outputs of which are connected respectively to the counting and installation Inputs of the main counter, signal

input key input is connected with counting | the input of the additional counter, and the signal inputs of the polling and power keys are connected to the third and fourth inputs 5 of the device, respectively.

The drawing shows a block diagram of the proposed device. The device for correction of the error of the account contains an additional counter 1, the main account is

0 tick 2, transfer keys 3, decoder 4, interrogation key 5, trigger 6, input key 7, blanking key 8, first 9, second 10,: third 11 and fourth 12 inputs of the device.

accounts works as follows.

In the original state mostly. 2 and an additional 1 counters information is not contained, at the output of the decoder 4

0 no signal, commands Transfer (input 9) Poll (input 11), Reset (input 12) no. I.

The counting cycle begins with the arrival of a predetermined number of pulses at input 1O.

new 2 and additional 1 counters. At the end of the counting cycle, input 11 is followed by the Poll command. If the number of pulses; entering additional counter i is greater than one or N, a signal appears at the output of decoder 4, 1 opens and polling key 5 for a polling command received at input 1. Trigger 6 flips and closes input key 7 and blanking key 8, /

At the end of the Polling command follows input 9, the Transfer command, the information recorded in main counter 2, is transferred in the inverse code to the supplementary:) counter 1. At the end of the Transfer command, it is followed by input 12 to the Reset command, which however does not return the main counter 2 is reset, since the blanking key 8 is closed by the output signal of the trigger 6. At the end of the Reset command, the receipt of a new pulse sequence at the input 1O of the device follows. However, these impulses are received only in additional counter 1, since the input key 7 is closed for input signals by the output signal of trigger 6. If the number of pulses received during this cycle in additional counter 1 is equal to or different from the previous value by + J pulse, then the additional counter 1 is filled with the value of 0.1 or M pulses, since the sum of the number of pulses in the main code with the same number of pulses in the inverse code is equal to the total capacitance Y of the counter. At the output of the decoder 4, there is no signal and the Poll command at input 11 does not pass via polling key 5. The trigger state 6 does not change. The INPUT transfer command 9 again transfers to the additional counter 1 the previous information in the inverse code. The Reset on input 12 command does not come through the key 8 for the installation inputs of the main counter.

 ka 2, and it stores the previous information.

If the number of input pulses differs from the original value by more than + 1 pulse, after the end of the count, a signal appears on the output of decoder 4, which opens the interrogation key 5 for the Poll signal. The trigger b is transferred and opens the input key 7 and the blanking key 8. The Reset signal, having passed through the blanking key 8, returns the main counter 2 to the initial state. Next, the pulse recording cycle is repeated. By changing the number of pulses at which a signal appears at the output of the decoder 4, it is possible to significantly increase the dead zone of the corrector.
