燃料电池单片电压巡检显示模块设计

The Design of Displaying Module about Cell Voltage Monitor System of Fuel Cell

为了能够准确实时的监测燃料电池单片电压,设计了单片电压巡检系统显示模块。该模块主要由单片机PIC18f258、液晶显示器CA12864F及键盘组成。单片机对采集的各单片燃料电池电压信号经滤波、统计分析后,将各单片电压及统计信息发送给液晶显示器,并通过按键导航控制液晶显示。该显示模块已在燃料电池巡检系统中得到成功应用。

In order to supervise cell voltage of fuel cell real timely and accurately, this paper has designed displaying module in the system of cell voltage monitor. The module was composed by PIC18f258, LCD CA12864F and keyboard. The PIC sent cell voltages and gather information to LCD after filter and statistic of voltage signal. Then, control it by key-press. It has being successfully used in cell voltage monitor system.
