Jiancheng Song · Colliery Mechanical & Electrical Technology · 2004
In this paper, MAX-EPM7128SLC84-15 chip is adopted in detecting BCD code of two-speed and two-loop magnetic starter. The logical schematic diagram is designed and some software programs are given. CPLD (Complex Programmable Logic Device) technology is applied in dialogue between operator and computer. The practice shows that by adopting CPLD in detecting BCD code the data are transmitted accurately and kept well secret, which is provided with higher applied value.
