摘要

7. A circuit for remote, automatic, multi-location monitoring, containing local stations and a central station which are connected via independent one-way transmission lines, characterized in that the local circuit (UL) has a memory circuit (1) for the inputs from the energy meters connected via a multiplexer (2) to a flip-flop (4), which is connected to one input of an adder (5), whose second input is connected to a memory circuit (7), while the output of the adder (5) is connected via a buffer register (6) to an input of the memory circuit (7), whose second input is connected via an address multiplexer (8) to a control circuit (12), and the output of the memory circuit (7) is connected to a transmitter (10) via an output register (9); the central circuit (UC) has, at its input, independent receivers (21) connected to a register (22), their outputs being connected to a data transmission control circuit (23) and to a local station decoder (25), and the outputs are connected to the control circuit (23) and an output register (26), whose other inputs are connected to the control circuit (23) and to an address counter (24) also connected to the decoder (25), while the output register (26) is connected to a microcomputer (27).IMAGE
