Definitions

  • the present disclosure relates in general to the field of information gathering, and more particularly to a system and method for remotely reading utility meters.
  • a typical and longstanding method of determining how much energy a consumer of electricity uses during a given time period involves the sending of an electric company employee to the consumer's home or business where an individual meter may be read. This process may require thousands of man-hours every reporting cycle. An employee may regularly visit several accounts in order to read the amount of energy consumed by each of the several accounts. These readings, which may be, for example, monthly, are often difficult to obtain because of such things as dangerous neighborhoods, unfriendly pets, and meters in inaccessible locations.
  • Some utility providers are beginning to use specialized devices that allow for automated meter reading.
  • Several companies manufacture such devices.
  • a utility provider e.g., a local electric company
  • the landline may be the telephone line providing service to the consumer's premises.
  • the device in the meter tracks and stores the utility usage and, on a regular basis, sends the usage data to the utility provider or a system manager collecting usage data for the utility provider via the landline. As such, the utility provider may no longer need to send an employee out every month to read a meter.
  • Utility companies have also automated the reading of meters with wireless systems. This approach alleviates the need for a landline, but implementation of the system may be relatively expensive especially for sporadic coverage of meters since a wireless backbone system must generally be installed for the entire coverage area.
  • an existing wireless system may be used, but this usually requires a relatively expensive device capable of two-way cellular communication to be installed in every meter to be read remotely and data transmission rates are not typically cost effective. The costs associated with installing this system may be prohibitive, especially when applying it as needed instead of en masse.
  • a system and method for remotely reading utility usage from utility meters are disclosed that provide significant advantages over prior developed systems.
  • the disclosed embodiments allow a utility provider to accurately and efficiently track, report, and bill for a consumer's utility usage.
  • a system incorporating teachings of the present invention may include, for example, a plurality of meter readers.

  • a meter reading system for remotely reading meters may, in operation, transmit a first utility usage signal from a first meter reader to a remote collector.
  • the operation may also include transmitting a second utility usage signal from a second utility meter reader to the remote collector.
  • Each of these usage signals may be converted into utility usage data for the respective utility meters.
  • This usage data may be stored at the remote collector. This storage may, in some embodiments, represent the first time usage data is stored.
