Abstract

The invention relates to an anti-oscillation circuit and method and an intelligent terminal. The anti-oscillation circuit comprises a standby power supply, a reset circuit and a system power supply circuit. The standby power supply is connected with the system power supply circuit, and the reset circuit is connected with the system power supply circuit which is connected to a to-be-powered system.The reset circuit comprises a reset chip, and the reset chip comprises a RESET pin. The system power supply circuit comprises a power supply chip. The power supply chip comprises an enable pin. The RESET pin is connected with the enable pin; when the standby power supply is started, the reset circuit controls the on-off of the power supply chip according to the voltage of the system power supplycircuit. According to the application, the enable pin of the power supply chip for supplying power to the system is controlled by using the reset circuit, so that the power supply of the system can beswitched off at the end of the power supply of the standby power supply, thereby avoiding repeated restart of the terminal caused by oscillation of the system voltage, and effectively preventing repeated oscillation of the output at the end of the power supply of the standby power supply.

Description

technical field [0001] The present application relates to the technical field of electricity consumption information collection, in particular to an anti-oscillation circuit, method and intelligent terminal. Background technique [0002] On the power consumption information collection terminal, according to enterprise standards, after the terminal is powered off, the terminal needs to work for another 3 minutes to save and upload data. At present, the domestic general method is adopted in the traditional technology, and the backup power supply is directly added to the terminal to meet this demand. [0003] During the implementation process, the inventors found at least the following problems in the traditional technology: During the test, it was found that the terminal would restart repeatedly at the end of the power supply using the traditional method of adding backup power. This phenomenon cannot occur, and traditional software and hardware cannot solve this problem. Co...
