Abstract
Изобретение относитс к вычислительной технике и автоматике и примен етс дл ввода и контрол датчиков дискретных сигналов в сложных информационно-управл ющих системах. Цель изобретени - по нттиСКльтс ых авповышение надежности и достоверности контрол датчиков дискретных сигналов за счет введени блока контрол достоверности, элементов И, изменени конструкции узлов св зи и введени новых св зей между указанными элементами. Устройство содержит матрицу 1 узлов 2 св зи,установленных на пересечении управл ющих 3 и информационных 4 шин, блок 5 опроса, блоки приема и индикации состо ни 7 и адреса 15, блок тестировани 11, блок 9 контрол достоверности и логические элементы И 17, что позвол ет контролировать целостность линии св зи с датчиком в случае разомкнутого контакта датчика и устанавливать достоверность прин того кода, а также обеспечиваетс возможность гор чего резервировани при построении схемы контрол с асинхронным принципом работы. 6 ил. Ю70 Ы. h«4;...lTttt со СThe invention relates to computing and automation and is used to input and monitor sensors of discrete signals in complex information control systems. The purpose of the invention is to increase the reliability and reliability of monitoring sensors of discrete signals by introducing a reliability control block, AND elements, changing the design of communication nodes and introducing new links between these elements. The device contains a matrix of 1 communication nodes 2 installed at the intersection of control 3 and information 4 buses, polling block 5, receiving and indicating state 7 and address 15 blocks, testing block 11, confidence control block 9 and logic elements 17, that allows you to monitor the integrity of the communication line with the sensor in the event of an open contact of the sensor and to establish the reliability of the received code, and also provides the possibility of hot backup when building a control circuit with an asynchronous principle of operation. 6 Il.
