This paper introduces the software structure and core technology of the automatic torque converter test system. In this system, the hierarchical structure and interface technology of the virtual instrument software are used to realize the flexible configuration of the test system. By setting up the measurement channel attribute model and the sensor attribute model based on the knowledge base, the interchangeability between the instrument hardware and the sensor ; Through the critical area locking technology to solve the multitasking concurrent process and database sharing security issues. The application of these key technologies improves the reusability of the test system software so that the user can upgrade the test system, exchange and update instruments and sensors without modifying the software source code, greatly reduce the maintenance cost of the test system, Extend its life cycle, access to user praise
