燃料电池检测与控制系统开发

Development of Fuel Cell System Monitoring and Control System

开发了可实现远程操控的燃料电池检测与控制系统。硬件方面将树莓派和Arduino作为系统的上位机和下位机,另基于改进差分放大器法设计了燃料电池单电压巡检模块;系统软件主要由4个模块构成:数据采集、数据上传、远程控制、GUI应用程序。该系统基于云技术可实现电脑和移动终端对燃料电池状态的实时监测、离线监测以及远程控制,具有体积小、功耗小、成本低、使用方便等优点,现已成功应用于重庆大学汽车燃料电池系统实验室,并取得较好成果。

This study presents a remote monitoring and control system of fuel cell. In the hardware system, the Raspberry Pi and Arduino are as the master board and slave board, respectively, after analyzing their function and performance. In addition, a single-voltage monitoring hardware module of fuel cell is designed by using an improved differential amplifier method. While in the software design, it consists of data acquisition module, data upload module, remote control module and GUI application. Finally, cloud technology is adopted to achieve real-time monitoring, off-line monitoring and remote control for fuel cell status by computers and mobile terminals. The designed system has several advantages, such as small size, low power consumption, low cost and easy to use. It has been successfully applied to a project of a fuel cell vehicle in the Chongqing University Fuel Cell Vehicle Laboratory.
