Claims (2)

1. Способ контроля, основанный на формировании блоком контроля сигналов опроса, технологических датчиков и ответных информационных сигналов о контролируемом этими датчиками процессе и передаче указанных сигналов по общей линии связи, отличающийся тем, что в качестве линии связи используют промышленную сеть переменного тока, а сигналы опроса и информационные сигналы формируют в виде пачек импульсов, частота следования которых синхронизирована напряжением промышленной сети, при этом, информационные пачки импульсов сдвигают относительно пачки опроса, на время, пропорциональное номеру опрашиваемого технологического датчика, а в качестве тактового сигнала используют напряжение промышленной сети.1. The control method, based on the formation by the control unit of the polling signals, process sensors and response information signals about the process controlled by these sensors and transmitting these signals over a common communication line, characterized in that an industrial AC network is used as the communication line, and the polling signals and information signals are formed in the form of bursts of pulses, the repetition rate of which is synchronized by the voltage of the industrial network, while the information bursts of pulses shift the relative survey of packs for a time proportional to the number interviewee process transmitter, and in use as a clock signal voltage of the commercial network. 2. Способ контроля по п. 1, отличающийся тем, что пачку сигнала опроса формируют с большим числом импульсов, чем пачку сигнала, информирующую о выполняемом технологическом процессе в каждом контролируемом канале. 2. The control method according to claim 1, characterized in that the packet of the polling signal is formed with a larger number of pulses than the packet of the signal informing about the process being performed in each monitored channel.
