Abstract:
A remote utility reading and control system includes a central utility use data bank which communicates by communications link with a plurality of relay modules located at power sub-distribution transformers. Each relay module separately addresses and communicates by PLC with a number of site units in its locality. The site units may include on/off controls for buildings, light systems or single pieces of equipment, or may include utility meters or real power meters. The PLC communication utilizes error checking and message verifying to acquire valid status or measurement signals, which are then transmitted to the central data bank. A CRC error code identifies faulty messages. After multiple interrogation, five responses are stored, and a message is confirmed only when three of five reponses are identical. Systems for electricity, water, and gas are described.
