【Abstract】 An intelligent measurement system of goat dynamic performance is developed to meet the demand of the national high speed train project. The system is composed of model ZX-Ⅱ measurement recording instrument of goat performance and data management system. The pulling force, voltage and current signals are measured in real time. Software filter and isolation technique between digital and artificial circuit increase the interference rejection ability of the measurement system. The results show that the system is reliable.更多还原
