The traditional method of engine test system existing time-consuming, low precision and massive data analysis problems, to improve this, introduced a method to constructing aircraft engine test system using LabVIEW. The test platform which is based on data acquisition card, serial and network can complete the environment adaptability and reliability test of the test object easily. Multi-threading technology and synchronization control technology are used in the software development process to solve the problem about integration and collaboration in the multi-frequency multi-tasking data acquisition system, and this method can improves the efficiency and effectiveness of the test.
