ABSTRACT:In highway vehicle energy recovery power generation system, vertical axis wind turbines placed on both sides of the road is the core of the system. In order to make the generator can operate better, get power efficiency is relatively high. Need to run parameters of the generator were measured.

In this paper is based on the STC15F2K40S2 MCU as the core controller, sensor, by Holzer RS232 and FM12864-12L liquid crystal display devices and C programming language used to design a simple vertical axis wind turbine run data recorder. The system can measure various parameters relative wind generators accurately when the wind wheel rotation speed, and the wind speed, the output voltage and current. Introduces the serial communication between data acquisition system of MCU and PC and single chip microcomputer, give full play to the MCU performance. The measured data can be displayed visually.

The hardware circuit is simple, the software function is relatively perfect, the control system is reliable and high performance price ratio is the biggest feature of the system.
