초록 ▼

The present invention relates to an automatic meter reading transponder. The transponder is comprised of a receiver for receiving an external instruction and a transmitter for transmitting data. A CPU is connected to the receiver and the transmitter. A ROM is connected to the CPU and ROM contains a program for controlling the operation of the CPU. A real time clock is connected to the CPU for determining sequential predetermined time periods. Three input terminals are connected to the CPU for receiving data to be stored in a RAM. One of the three input terminals has pulses impressed thereon, the number of pulses being representative of electric power consumption. The one input terminal is also connected, via the CPU to a time-of-day memory. The memory is comprised of a plurality of discretely addressable registers wherein the CPU equates each addressable register sequentially with a consecutive one of the predetermined time periods, so that each register sequentially contains a count which is representative of the power consumed during its associated time period or any fraction thereof. The CPU activates the transmitter to transmit data upon receipt of the external instruction. The data is, in part, the contents of each register in the time-of-day memory transmitted in sequence.
