摘要
为了详细分析ATT7022B在ARM上的实际应用的方法,阐述了电能芯片ATT7022B的特性和工作原理,并结合在矿用综合保护器项目中对各项电力参数采集的应用,给出了LPC2292与ATT7022B硬件接口设计和软件编程实现方法。利用该设计能够很好地测量各项电力参量,极大地减小了计算上的误差和设计复杂性。测试的结果表明ATT7022B具有精度高,操作方便等优点。
For analysing of the way of practical application of ATT7022B in ARM in detail, the identity and principle of energy chip ATT7022B are introduced, and combining with the applications of protection devices in the mine for the parameters collection, the design of LPC2292 and ATT7022B hardware interface and Software programming are given. The design paramters can be used to measure various very well, and the calculation error and design eomplexing are reduced. The test results show that ATT7022B has a high accuracy, easy to operate, and other advantages.
