By integrating the battery charging and discharging and power detection module, the peripheral device power supply voltage regulating module, the switch control module and the like, the device can effectively manage the power supply of the millimeter wave cloud radar automatic test instrument, ensuring the convenience and stability of the instrument in field testing and use. The power management master can monitor the battery power state, charging and discharging process and the electrical parameters of peripheral devices in real time, intelligently control the on-off of the charging circuit through data analysis and processing, prevent overcharging or undercharging of the battery, and prolong the service life of the battery. Through the state display module, users can intuitively understand the working state of each device (or module) of the millimeter wave cloud radar automatic test instrument, the battery power condition and the internal environment temperature and humidity condition of the instrument, discover and handle abnormal conditions in time, and improve the reliability and safety of the equipment.
