Power supply monitoring method and system

Abstract

The invention relates to a power supply monitoring method and system, and the method comprises the steps: obtaining the temperature information of a current power supply circuit through a temperature monitoring structure, carrying out the analog-to-digital conversion of the temperature information, transmitting the converted data information to a numerical value display structure, and when the temperature information is larger than a preset threshold value, enabling the numerical value display structure to display the temperature information; the method comprises the following steps: determining a fault of a target power supply, sending a cut-off signal to a power supply control device, collecting voltage information of a current circuit through a voltage monitoring structure, carrying out analog-to-digital conversion on the voltage information, sending the converted data information to a numerical value display structure, and driving a piston to move through expansion according to the preheating expansion characteristic of expansion oil. The heat of the circuit is obtained by measuring the movement distance of the piston, and the circuit is cut off when the heat reaches a certain value, so that the circuit is protected.

Description

technical field [0001] The invention relates to the related field of circuits, in particular to a power monitoring method and system. Background technique [0002] The power supply is a device that converts other forms of energy into electrical energy and provides electrical energy to the circuit (electronic equipment); the power supply is based on the principle of "magnetism" and is composed of renewable energy such as water power, wind power, sea tide, dam water pressure difference, solar energy, and Burn coal, oil residue, etc. to generate electricity sources. [0003] Common power sources are dry batteries (direct current) and household 110V-220V AC power sources. [0004] Power supply monitoring is a real-time monitoring of one or more of the input voltage, operating frequency, operating frequency, refresh rate, overload capacity, and overload capacity; [0005] However, most of the monitoring equipment only raises the early warning when the power supply value is less...

AI Technical Summary

Problems solved by technology

[0005] However, most of the monitoring equipment only raises the early warning when the power value is less than or greater than the specified value, and does not perform real-time protection. It still needs to be done manually, and the degree of automation is relatively low.
