Research on Diesel Generator Controller for Base Station

摘要:

针对山区、偏远乡村等地的通信基站用柴油发电机设计一款专用控制器；基站使用柴油发电机供蓄电池充电作为电源,控制器实现蓄电池电量监控,显示以及控制柴油发电机自动停开机和对蓄电池充电的功能；控制器以具有Cortex-M4内核的STM32F407芯片为核心,通过μC/OS-II实时操作系统和PID算法对发电机和蓄电池充电进行实时控制；实验表明,控制器能够实现发动机的自动控制,在为蓄电池充电过程中恒压波动小于±0.1 V,恒流波动小于±0.2 A,实现蓄电池快速稳定充电,满足基站的供电需求。

Abstract:

Design a dedicated controller to control the diesel generators which is used as power source for the communication base station built on the island or remote village. Base station uses the battery as a power source, the controller monitors the battery power and control diesel generator to charge the battery.The controller use STM32F407 chip with Cortex-M4 architecture as the core and use μC / OS-II real-time operating system and PID algorithm to ensure the stability of the battery charging. Experiments show that the generator can be automatically controlled by the controller and the charging voltage and current fluctuations were less then ±0.1V and ±0.2A.
