Abstract

The invention discloses a power management device which comprises a power circuit and a control unit, wherein the power circuit receives an input power having a voltage value, and the voltage value isrespectively converted into a first converted signal having a first voltage value and a second converted signal having a second voltage value by a first voltage converter and a second voltage converter; the first voltage converter restarts according to a first reset signal, and the second voltage converter restarts according to a second reset signal; the control unit receives the corresponding first converted signal and the corresponding second converted signal, and compares the first voltage value with a first reference range and the second voltage value with a second reference range; when the first voltage value is not in the first reference range and the second voltage value is in the second reference range, the first reset signal is transmitted; and when the first voltage value is inthe first reference range and the second voltage value is not in the second reference range, the second reset signal is transmitted.

Description

technical field [0001] The invention relates to a power management device and method, in particular to a power management device and method for electronic equipment or machines. Background technique [0002] With the advancement and development of science and technology, people rely more and more on the convenience brought by electronic products in their daily life. In addition to facilitating people's lives in daily life, electronic devices can also be used in various industries. As far as the photography industry is concerned, assuming that it is necessary to take a long-term record of the life of observing wild animals, it is impossible to do it manually for a long time. Therefore, it is often necessary to set up outdoor prey trackers in specific places where wild animals often appear. Since the outdoor prey tracker is set up in the wild for a long time and left unattended, when the power supply is unstable due to certain factors, it is easy to cause malfunction of the m...
