SU570206A1 - Multichannel pulse counter - Google Patents

Description

one- .;..,

The invention relates to computing and can be used to calculate the total number of pulses over several channels.

A multichannel counter is known that contains ij memory elements,

The disadvantage of such a multichannel counter is the possibility of losing information in case of coincident polling pulses with count pulses.

Also known Multichannel pulse counter, containing: storage cells, the elements of OR and AND, and the outputs of the storage cells are connected to the first inputs of the first elements AND

The disadvantage of this device is the low accuracy of the counting, which is associated with the loss of information in the event that the polling pulses of the storage cells coincide with the counting pulses.

The purpose of the invention is to increase the accuracy of the account.

This is achieved by the fact that a multichannel pulse counter containing memory cells, elements AND and OR, and

The memories of the memory cells are connected to the first inputs of the first elements And, additionally, a polling pulse generator, a distributor, a NO element, a delay element, and an anchor are added. In this case, the outputs of the storage cells are connected to the inputs of the first element OR, the output of which is connected to the first direct input of the NO element, the second direct input of which is connected to the output of the polling pulse generator, the input of the NO element is connected to the distributor input, and the inverse input of the NO element is connected to the output the second element OR, the input of the element delay and the indicator input, the outputs of the distributor are connected to the second inputs of the first elements AND, the outputs of which are connected to the first inputs of the second And elements, the second inputs of which connected to the output of the delay element, and the outputs of the second elements And are connected to the installation inputs of the memory cells.

The drawing shows a structural circuit of a multi-channel pulse counter.

Mnogokanalny counter nmpupsrv sodergkvt aapomivayushayyshe cell 1, epegpy AND 2 AND 3, the elements OR 4 and 5, the generator 6 polling pulses, the distributor 7, the epemite NO 8, SieflepscKHfl indicator and the indicator number 10 and the set of the set of the set of set numbers and the set of the numbers of aaflepscKHfl and the indicator Both 2 and the inputs of the first segment OR 5, the output of which is connected to the first direct INPUT element NO 8, the second direct input of which is connected to the output of the generator 6 of polling pulses. The output of the element NO .8 is connected to the input of the distributor 7, and the inverse input of the element NO 8 is connected to the output

the second element OR 4, the input of the delay element 9 and the input of the indicator 10. The outputs of the distributor are connected to the second inputs of the first AND 2 elements, the outputs of which are connected to the first inputs of the second elements AND 3, the second inputs of which are connected to the output of the delay element 9, and the outputs of the second elements And 3 are connected to the installation notes memorizing cells 1 ..

The device operates as follows When one or several pulses of the pair arrive at the inputs; storage cells 1 signals from the outputs of storage cells 1 are fed to the inputs of elements AND 2 and through the element OR 5 serves the enabling signal to the logic element NO 8, which connects v (generator 6 pulse of the interrogation to the vtschadu, -distributor 7, Distributor 7 YYat impulses to their outputs up to X then, wy & a signals from its output do not coincide with 1x signals from cell 1 that operated, after which the signal from the selected element AND 2 goes through the element OR 4 to the inverse input of the element NO 8, stopping thereby distributing When the delay element 9 is used for the time needed to write the counting pulse into the indicator 10. The signal from the delay element 9 then switches the corresponding element 3, returning the activated

Shake cell i in the initial state and preparing it for receiving the following pulse count. The signal from the inverse input element NO 8 is removed, and the distributor 7 continues to search for the next cell 1, which is in a single state.

Thus, in a multichannel counter, lost information is eliminated if the input pulses coincide with the polling pulses.
