2011 2nd Asia-Pacific Conference on Wearable Computing Systems

作者： Zheng-wei HU Laurent CHARLES Patrice MEDINA Christine HU North China Electric Power University

In order to develop a robust bio-logging system, one design method based on ASIC and multi-sensors was proposed in this paper. Due to the cost of ASIC design, XC3S1500-4FG20, one type FPGA of Xilinx Corporation, was selected for prototype test firstly. The final purpose of this design is to design one Application Specific IC to realize control functions of acquiring data with all the devices in this logging system. Light sensor, temperature sensor, pressure/temperature sensor, 3-D accelerator sensor, RTC and SD card six devices in total were included in this system. Each device was selected based on its functions and power dissipation. Interfaces that control data transfer between devices and FPGA were designed dedicatedly. For reusability, three level division method was proposed and adopted in design of interfaces. The FPGA prototype was design by using VHDL. An interface of RS232 was designed for transferring data between FPGA and PC. The acquired data were draw into graph by using MATLAB for visibility. Simulation was done in one lab of IPHC Strasbourg for 18 days. The correctness and efficiency can be confirmed by simulation results.
