Research Of The Comprehensive Testing System For Aero-Generator

This paper introduces an Aero-Generator testing system. Integrating virtual instrument technology with microcontroller technology, the system completes the test of regulation project and the recode of operation condition for Aero-Generator. The test system not only can use on test, regular check and fault detection for Aero-Generator, but also can apply to the normal mechatronics detection system.The hardware of this system is made of 3 parts. They are AC electronic load module, data acquisition and storage module, and data transmission module. Considering different equipment and practical need of simulation on the ground, an AC electronic load system has been designed for the Aero-Generator basing on PWM Technology, MCU and high power. In provide of satisfying the users, basing on MCU, an airborne data acquisition system has been designed to count the real time gathering circuit. In order to satisfy the need of high speed data storage for airborne equipment, an application system has been designed with 16MB storage capacity basing on MCU. The data transmission module has also been designed to satisfy the data transfer with the controlling software and hardware. Can bus transformation RS-232 bus has been used in the transmission module. Meantime, we design two kinds of power supply module and analyze the anti-disturbance design of system.Taking Lab Windows/CVI 6.0 as developing tool, the Aero-Generator software system is designed, realizing the control of AC electronic load, data collection and record. The software of this system solves the problems and improves the nature for the ant jamming by human. Meanwhile the technology of multi-threading can be used to realize the concurrent processing and improve the ability of real-time. Surely, the technology of multi-threading can be used to realize the concurrent processing and improve the ability of real-time. In the end, this paper accomplishes the function of effective data storage, printing testing reports and characteristic curve, and so on.The AC electronic load, data collection, and recording module have been deployed. The system which runs stably and reliably achieves the expected functions and precisions.
