ABSTRACT:
A call in-bound remote reading and data collection system for the remote reading of utility meters, including a data processor and a remotely located meter interface unit (MIU) interconnected to at least one utility meter to be read. Also disclosed is a meter interface unit and a method for the remote reading of utility meters and the collection of data. The data processor collects, stores and processes data and includes a modem to interconnect the data processor to conventional telephone lines. The MIU is interconnected to the telephone lines and the data processor, to transmit scheduled meter reading to the data processing means, when a prespecified interval has elapsed. The MIU is also interconnected to transmit unscheduled or demand meter readings when the MIU receives telephone line transmissions requesting such a reading (e.g. receipt of a specified tone). A modem is used to interconnect the MIU so it can communicate over the telephone lines. The MIU includes a microprocessor that generally controls the operation of the MIU and supervises the transfer of data between the data processor and the meter interface unit. Specifically the microprocessor processes commands from the data processor and outputs data, in response to the commands received, to the data processor.
