In order to improve the current testing status of the missile control cabin,a kind of control cabin testing system taking PXI bus industrial computer as its core was designed. In this system,high precision sensor and signal conditioning circuit is used for data acquisition,and CPLD is used to execute the angle value resolving of incremental encoder and the time?sequence control of the exciting signal,which cooperate with the monitoring software on Visual Studio platform to carry out data analysis and processing. On the basis of the testing system architecture,the circle built?in test design makes full use of the flexibility of CPLD,which greatly saves the resources of hardware. The circle built?in test of the system was achieved,which improved the reliability of testing system. The control cabin testing system with high precision,high efficiency and low error was realized.
