Description
(54) УСТРОЙСТВО ДЛЯ КОНТРОЛЯ СОСТОЯНИЯ ОБЪЕКТОВ(54) DEVICE FOR MONITORING THE CONDITION OF OBJECTS
Изобретение относитс к технике автоматического контрол и может быть применено дл обегающего контрол состо ни технологических датчиков, в том числе и датчиков сигнализации.The invention relates to an automatic control technique and can be applied for ambient control of the state of process sensors, including alarm sensors.
Известно устройство дл контрол , в котором дл передачи сигналов от технологических датчиков используютс многожильные кабели, а опрос датчиков осуществл етс путем посылки сигналов кодового выбоpa соответствующего датчика по нескольким жилам кабел I.A control device is known in which multi-strand cables are used to transmit signals from process sensors, and the sensors are polled by sending code signals from the corresponding sensor over several wires of cable I.
Это устройство не позвол ет контролировать исправность линии св зи, нарущение которой (обрыв или короткое замыкание) приводит к по влению ложной информации. This device does not allow monitoring the health of the communication line, the violation of which (interruption or short circuit) leads to the appearance of false information.
Из известных устройств наиболее близ-ким по технической сущности к предложенному вл етс устройство дл контрол состо ни объектов, содержащее блок опроса m групп технологических датчиков, выходы, которого соединены с управл ющими входами m ключей и с первыми входами блока обработки информации, вторые-входы которого подключены к выходам п приемниковOf the known devices, the closest in technical essence to the proposed is a device for monitoring the state of objects, comprising a polling unit of m groups of process sensors, outputs that are connected to control inputs of m keys and with first inputs of information processing unit, second inputs which is connected to the outputs of the n receivers
сигналов, выходы ключей соединены с m контрольными проводами линии св зи, к каждому из которых подключены первые клеммы переключающих контактов п-1 технологических датчиков 2.signals, the outputs of the keys are connected to the m control wires of the communication line, each of which is connected to the first terminals of the switching contacts n-1 of the technological sensors 2.
Это устройство ненадежно в работе, поскольку возможен прием ложной информации при нарущении линии св зи или выходе из стро приемников сигналов.This device is unreliable in operation, since it is possible to receive false information if the communication line is broken or the signal receivers are deactivated.
Цель изобретени - повыщение надежности устройства.The purpose of the invention is to increase the reliability of the device.
