摘　　要：为提高柴油机ESC测试效率,利用RS485通信,将排放测试设备做成网络节点,并在工业组态软件中编程,实现测试过程自动化.系统用于4 JB1柴油机标定实验中,经试验验证,ESC自动测试系统效率高,其数据分析功能能指导工作人员优化标定参数,系统自开发至今运转正常.In order to increase the efficiency of testing the ESC for a diesel engine, relevant emission measuring devices were used to be network nodes by means of RS485 and test process automation was achieved by programming in Industrial Configuration Software. This system was used in the calibration experiments of a 4JB1 diesel engine. The results illustrated that the ESC system reached a higher efl＇iciency in testing process, and its function on data analysis was helpful for testers to optimize the calibration parameters.
