【Abstract】 With the train speed increase and heavy haul technology developed in our country, the existing single car brake tester can′t meet the required test functions and accuracy, so a new automatic test method base1d on PLCs and their communication technology are presented. Then the system′s architecture and its main working principle are described.更多还原
