METHOD FOR CHECKING Russian patent published in 1998 - IPC

FIELD: agricultural manufacturing, in particular, stationary grain processing stations. SUBSTANCE: method involves use of alternating current power supply line for communication, generation of request signals and information signals as pulse bursts which rate is synchronized with voltage of power supply line, shift of information pulse bursts with respect to request pulse bursts by duration which is proportional to number of gauge to be requested. Clock signal is voltage of power supply line. Burst of request signals has greater number of pulses than burst of information signals. Invention specification provides principal circuit of device which implements said method. EFFECT: increased functional capabilities. 2 cl, 2 dwg
