Design of power supply system on a data recording device
As the special working environmentSofSpower supply system on data recording device, it proposes a rechargeable power supply system that can realize power change from ground power to power itself, and manage the charging of lithium battery. It introduces the process of power change through enable port of linear regulator controlled by power control module, and the management of lithium battery charging by BQ2057. It also gives the reliability designs such as prevention of single sensor short circuit, cooling optimization, lithium battery technology. Tests show that, this power supply system is stable, safe and reliable, and can supply more than 2 hours.
