摘 要：The working condition of the condenser in power plant is an important factor that affects the economic operation of the power plant.Rubber ball cleaning is a main method to deal with the condenser fouling.The thesis,dealing with the problem of counting errors of rubber ball in the process of condenser cleaning,based on CPLD(Complex Programmable Logic Device) technology,designs a programme have rubber balls checking and counting automatically.The program takes use of the controlled laser sensors to count the number of rubber balls in every single pipe and the parallel processing capacity of CPLD,and have the number of different pipes counted and shown.Experiments have proved its constancy and accuracy.
