【摘要】：为了解决磁跟踪系统体内装置的能量供应问题,研究了一种低功耗、高效、智能化的能量管理方法.主要包括主控制器、升压电路、非接触式开关、电源路由器和负电荷泵.随着纽扣电池电量的消耗,升压电路由主控制器智能化选通,当电池电压大于3.3V时关断,小于或等于3.3V时开启,由此减小了升压芯片在前期的能量损耗.另外,主控制器进一步控制电源路由器,根据体内装置的工作状态,按照需要选通后级电路.经实验验证,能量管理模块可延长纽扣电池的工作时间,最大程度地降低了无效能量损耗,满足磁跟踪系统完成消化道检查所需的时间要求.
[Abstract]:In order to solve the problem of energy supply in magnetic tracking system, a low power, efficient and intelligent energy management method is studied. Includes main controller, boost circuit, non-contact switch, power router and negative charge pump. With the consumption of button battery, the booster circuit is intelligently switched on by the main controller. When the voltage of the battery is higher than 3.3 V, and when the voltage is lower than or equal to 3.3 V, the energy loss of the booster chip is reduced. In addition, the main controller further controls the power supply router, according to the operating state of the device, according to the need to switch the back stage circuit. The experimental results show that the energy management module can prolong the working time of the button battery, reduce the invalid energy loss to the maximum extent, and meet the requirements of the magnetic tracking system for completing the digestive tract examination.
