Abstract: Utilizing the communication interface of standard equipment and based on the VEE Pro software-exploiting platform, an automatic calibration platform was designed for the test load control and data acquisition system. It contains four main modules, i.e. equipment information collection module, servo control channel calibration module, data acquisition channel calibration module and printing module. The functions of real-time display, error alert, data processing and data automatic saving can be realized. Practices show that the platform is reliable, effective and accurate. It plays an important role in all kinds of helicopter experiments, and can be applied widely.
