Abstract: In order to solve the problem on which manual meter reading is of heavy work, time consuming and error prone, intelligent watt-hour meter based on wireless technology was designed. Considering the requirement of function and performance, the implementation scheme of intelligent watt-hour meter based on wireless technology was provided. MSP430F149 was used as the core processor. Electric energy acquisition was realized through transformers and ADE7755. The wireless function is realized by Si4432. Then the module circuits of the clock, the memory, the reference source, the display and the power supply were designed. Based on the hardware platform established, the software function of the watt-hour metering, wireless meter reading and multi-rate watt-hour metering were developed. Through testing, the requirement of function and performance of intelligent watt-hour meter are met in this design. A good solution to the promotion of electric energy automatic metering and reading is provided.
