摘要
根据便携式拉曼光谱仪的电源需求,设计了一种小体积、数字化的电源管理系统。该电源管理系统以STM32为主控芯片,采用TI公司的电池管理芯片BQ3060和BQ24005实现锂电池的管理,设计了供电电源切换模块和开关控制模块分别用于控制双电源的切换和系统的开关机,利用DC/DC转换模块保证系统恒定的电压输出,最后通过软件编程协同各个子模块使系统能实时查询电源状态且自行调整供电策略。该电源管理系统经制板调试后以小型拉曼光谱系统作为负载进行供电测试,结果表明,该系统供电过程中输出功率平稳,温度变化范围小,能实时管理电源并向用户反馈供电电源状态,满足设计需求,为便携式拉曼光谱仪的电源管理设计提供了良好的解决方案。
According to the power demand of portable Raman spectrometer,a small volume,digital power management system is designed.This power management system takes STM32 as the main control chip,adopts TI company′s battery management chip BQ3060 and BQ24005 to realize the management of lithium battery,designs the power supply switching module and switch control module to control the double power supply switching and the system switching machine,and uses the DC/DC conversion module to ensure the constant voltage output of the system.Finally,through software programming,the system can inquire the power supply status in real time and adjust the power supply strategy.After debugging the power management system with small Raman spectroscopy system as the load power supply test,the results show that the system’s power supply,small temperature change range,feedback can real-time management of power supply and power supply condition meet the design requirements.This system provides a good solution for portable Raman spectrometer power management system.
