Realize the flexible switch of various types of sensors connected to the hardware board; In the process of production, dynamic reconfiguration technology can be used to dynamically and real-time configure system functions, configuration is flexible and convenient, and improve the utilization of hardware resources. In this paper, a FPGA chip is implemented. The combination of sensor data acquisition technology and reconfigurable technology. Compared with the common data acquisition equipment, the design improves the speed of data acquisition and processing, not only can static reconfigure the system functions. It can also reconfigure the functions of the system in real time. This design has made a new attempt for the sensor data acquisition in the field of industrial automation. It also provides a new model for the development of the next generation sensor data acquisition technology.
