Power supply management method and power supply management device

Abstract

Embodiments of the invention provide a power supply management method and a power supply management device. The method comprises the following steps: a power supply management device detects whether a first power source outputs power; when detecting that the first power source outputs power, the power supply management device makes a channel supplying power to electronic equipment connected so as to enable the first power source to supply power to the electronic equipment; and when detecting that the first power source outputs no power, the power supply management device makes the channel disconnected after the channel is in a connected state for a first period of time, so as to switch a second power source from a state of supplying power to the electronic equipment to a state of stopping supplying power to the electronic equipment. According to the method and the device provided by the embodiments of the invention, the problem that the electronic equipment is often powered off abnormally when powered by a single channel of power source and the problem that the power source runs out due to long-time use of the other channel of power source are avoided, and the reliability of the equipment is improved.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and in particular to a power supply management method and device. Background technique [0002] With the popularity of smart devices, more and more mobile vehicles have begun to deploy on-board smart devices. For example, intelligent routers are deployed on buses and coaches, and the intelligent routers provide functions such as wireless network hotspot access and uplink data access. In order to maintain the normal operation of the vehicle-mounted smart device, it is often required that the mobile vehicle provide working power for it. Generally, the mobile vehicle can provide two types of power sources for the on-board smart devices: one is powered by the engine; the other is powered by the on-board battery. But often only a single power supply can be used to power the vehicle-mounted smart device. [0003] If only the electricity output by the engine is used to power the on-boa...
