Abstract

The invention discloses an energy-saving control circuit of an embedded system. The circuit comprises a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a sixth resistor, a first triode, a second triode, a first diode, a second diode, a first capacitor, a voltage stabilizing tube and a key. The circuit is connected with a battery and the embedded system respectively in a battery power supply system, the turn-on / off of a power supply system is controlled through control of the key, and the embedded system is used for judging power supply or end of the power supply of the battery power supply system according to a key signal in order to determine whether to switch off a battery or not. The energy-saving control circuit has the advantages that the adoption of the battery for supplying power is judged accurately according to the operation of the key by a user, the battery is switched off directly when power is not supplied, the battery power supply is not turned off, and the energy consumption of the battery is not in a consuming state, thereby improving the constant power supply capacity of the battery power supply system.

Description

technical field [0001] The invention relates to an embedded system control technology, in particular to an energy-saving control circuit of an embedded system. Background technique [0002] With the development of modern technology, embedded systems have been widely used in various industries, and have been widely used in battery-powered systems. As the core part of the battery-powered system, the embedded system controls whether or how the battery in the battery-powered system supplies power. Its performance directly affects the continuous power supply capability of the battery-powered system. [0003] In the existing battery-powered system, the embedded system usually controls the battery to enter the working state or standby state according to the received input signal, but even when the embedded system is working in the standby state, the battery-powered system will have tens to hundreds of The current of uA exists, and the energy consumption of the battery is always in...
