摘　　要：本文介绍了一种采用CAN总线的多用户电能表设计。首先介绍了CAN总线优点和电能表的特点以及硬件方案设计,接着详细探讨了电能表主要模块功能。该电能表既可以计量多户家庭的用电情况,还具有断电控制、实时处理速度快、性价比高的特点;尤其,增加可透支用电的设计,具有人性化的优点。The design of multi-user Watt - hour meter based on the CAN is presented in the paper. First, The advantages of CAN and the trait of the meter,and the overall structure design are introduced. Second, the main module units are discussed in detail. The meter not only can measure the power for muhihousehold families, but also has the advantages of Power control,real- time processing speed, and high performance cost rate. In particular,the meter has the humanized advantages of overdraft consumption of energy in the design.
