摘要
为了实现便携式光电瞄准镜电池信息监测,考虑到光电瞄准镜低功耗、小尺寸的要求,提出一种仅使用单片FPGA作为处理器的电池监测系统结构。系统对2个串联的18650电池进行实时状态监测,FPGA对电池信息和图像信息进行同步融合叠加,在OLED屏上显示。显示屏上可以直观看到剩余电量、电池温度、电压、电流信息,当电池电量不足或者电流、电压异常时,通过字体颜色变红给出相应警示。经过多次反复系统实验,光电瞄准镜的电池监测系统具有精度高、稳定性高等特点,具有工程实用性。
In order to monitor the battery information of portable photoelectric sighting telescope,considering the requirement of low power consumption and small size of photoelectric sighting telescope,a structure of battery monitoring system using single-chip FPGA as processor is proposed in this paper.Two 18650 series battery packs are monitored in real time by the system.Battery information and image information are superimposed synchronously by FPGA,and displayed on OLED screen.Surplus electricity,battery temperature,voltage and current information can be seen intuitively on the display screen.When the battery capacity is insufficient or the current/voltage is abnormal,the corresponding warning is given by reddening the font color.After repeated system experiments,the battery monitoring system of photoelectric sighting telescope has the characteristics of high accuracy and stability,which has engineering practicability.
