Abstract

Embodiments of the invention disclose a watchdog-based power supply circuit, a meteorological station, a power supply method and a watchdog; the input end of a power-on control module in the power supply circuit is connected with a power supply, and the output end of the power-on control module is connected with a power utilization module; the control end of the power-on control module is connected with the output end of a watchdog module; the power utilization module outputs a dog feeding signal, a dog feeding length setting signal and a working mode signal for expressing the working mode ofthe power utilization module to the watchdog module; and the watchdog module is used for setting the dog feeding duration in the working mode expressed by the working mode signal according to the received dog feeding duration setting signal, and controlling the power-on control module to supply power to the power utilization module or stop supplying power according to whether the dog feeding signal is received or not within the dog feeding duration, so that a relatively long feeding time can be set when the power utilization module is in a sleep mode, the power utilization module has a relatively long dormant time in the sleep mode so as to reduce the power consumption of the power supply, and the power supply can quickly recover electric energy.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of power supply, and in particular to a power supply circuit based on a watchdog, a weather station, a power supply method and a watchdog. Background technique [0002] The weather station is an outdoor device that can monitor plant growth, collect soil data and weather information. Since the weather station is located outdoors far away from the urban area, the weather station is usually powered by solar panels. [0003] Since the weather station is controlled remotely, it is inconvenient to deal with abnormal problems on the weather station on the spot. Usually, a watchdog is set on the weather station to reset the system and restart the to normal working condition. [0004] However, the feeding time of the watchdog is relatively short, generally within a few seconds, and when the weather station is performing tasks with high power consumption such as video or voice communication,...
