Method and system for monitoring and transmitting utility status via universal communications interface
View Patent ↗A method and system for monitoring utility meter status, and transmitting a status message via an output device connected to a universal communications interface in the event that the utility meter status meets a predetermined condition. Typically, the predetermined condition is a power loss, signified by a drop in voltage or current. The system is connected to a utility meter, such as an electric meter. The voltage level of the electric meter is monitored through a voltage input interface. An analog-to-digital converter transforms the voltage waveform into a series of digital data packets, which are then transmitted to a microprocessor. The microprocessor monitors the digital signal for a power loss indication, or other predetermined condition. Once a predetermined condition is met, the microprocessor transmits a status message across a universal serial bus to a universal communications interface. The universal communications interface is connected to at least one slot, which contains at least one output device. The universal communications interface is further able to determine the proper signal format employed by the output device for information transmission. Upon receipt of the status message, the universal communications interface converts the status message to the signal format employed by the output device, and passes the converted status message to the output device via the slot. The output device may then transmit the status message to a remote receiver in order to quickly and accurately update distant locations regarding the utility meter.
1. A system for monitoring and transmitting utility status via a universal communications interface, comprising:
an input interface operative to receive a utility status signal from a utility meter;
a processor functionally coupled to the input interface for receiving the utility status signal from the input interface and operative to generate a status message based on the utility status signal;
a universal communications interface, local to the utility meter, functionally coupled to the processor and configurable for communicating with a plurality of different types of communication devices, each different type of communication device operative to communicate with a receiving device via one of a plurality of different communication mediums;
a slot functionally coupled to the universal communications interface and configured to interchangeably connect one of the plurality of different types of communication devices;
wherein the processor communicates with the universal communications interface to determine which one of the plurality of different types of communication devices is connected to the slot; and
wherein the processor formats the status message into a format compatible with the connected communication device and transmits the formatted status message to the universal communications interface for transmission to the connected communications device.
2. The system of claim 1 , wherein the plurality of different communication mediums are selected from the group consisting of radio frequency waves, telephone lines, cable lines, fiber optic lines, satellite links, and power lines.
3. The system of claim 1 , wherein the utility status signal comprises an analog wave form; and
