Digital inputs are processed by fpga after being isolated by photocouplers . the results of digital inputs saved in fpga are read by tms320lf2407 periodically . the digital outputs being written to fpga are used to control empcs after being isolated by photocouplers and driven by darlington transistors 由于数字量的路数较多，因此采用了fpga进行扩展和简单处理，数字量输入通过光电隔离后送给fpga进行软件滤波，其结果由tms320lf2407定时读取； tms320lf2407输出的数字量先送给fpga ，再由fpga经过光电隔离和功率驱动后去控制机电式功率控制器。
