The shortages of classic BP Neural Network for fault diagnosis of analog circuit are put out. A method is put forward to improve the classic BP Neural Network. 分析了传统BP型神经网络在模拟电路故障诊断中应用所存在的缺点,提出了解决办法。
The data is sent to A / D through conditioning circuit, and then it is sent into PC by FIFO buffer through EZ-USB. After algorithm conversion, the D / A conversion outputs analog signal to carry out real-time control. 采集的数据经调理电路送A/D模数转换,再由FIFO缓存器经EZ-USB送上位机处理。经算法变换后的数据,由D/A转换输出模拟信号,实现实时控制。
Analog computation is carried out of the operating conditions of the saturator-hot water column by the use of the PRO - ⅱ software. 应用PRO-Ⅱ软件模拟计算饱和热水塔的工作状态。
When digital TV will replace analog TV, analog TV and gradually fade out the market. 届时数字电视将代替模拟电视,模拟电视逐步淡出市场。
