Problems solved by technology

However, the existing smart sockets generally have the following defects: 1. It does not have a wave recording function, and cannot effectively record the working status of the components during use.
2. If a fault occurs, the socket will fail after a power outage and will no longer have any functions
As a result, this type of smart socket cannot completely and effectively record the changes of power-related parameters during the fault occurrence process, which is not convenient for subsequent analysis

Embodiment Construction

[0025] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0026] see figure 1 , an intelligent socket with a power failure fault wave recording function of the present invention includes a signal processing unit, a zero-crossing switching unit, a communication unit, a control unit, a wave recording unit, an energy storage element, an interface unit and a power supply.

[0027] The signal processing unit collects voltage and current waveforms, performs filtering and shaping, and converts them into tested signals that can be input to the control unit.

[0028] The zero-crossing switching unit performs switching and switching control on the load at the output end of the smart socket when the voltage and current cross zero.

[0029] The communication unit is used for the communication between the control un...

Abstract

The invention discloses an intelligent socket with a power failure fault wave recording function, comprising a signal processing unit, a zero-crossing switching unit, a communication unit, a wave recording unit, an energy storage unit, a control unit and a power supply; the signal processing unit collects voltage and current The waveform is filtered and shaped, and converted into a tested signal that can be input into the control unit; the zero-crossing switching unit will switch on and off the load at the output end of the smart socket when the voltage and current cross the zero point respectively; the wave recording unit is used for recording The number of cycles before and after the power outage is calculated, and transmitted to the host computer to form a real-time changing curve; the control unit performs discrete wavelet transform and signal energy analysis on the tested signal input by the signal processing unit to determine whether there is an arc fault on the load side and its level, and Decide on the appropriate action. The invention can record the waveforms before and after the fault occurs when the socket loses power when the fault occurs, which is convenient for fault location and subsequent fault cause analysis.

Description

technical field [0001] The invention belongs to the technical field of intelligent power distribution and utilization, and in particular relates to an intelligent socket with a power failure fault wave recording function. Background technique [0002] Existing smart sockets are designed based on remote monitoring of electrical equipment, and are mainly used in the field of smart homes, which can realize data collection and data transmission under normal working conditions. However, the existing intelligent socket generally has the following defects: 1. It does not have a wave recording function, and cannot effectively record the working status of the components during use. 2. If a fault occurs and the power is cut off, the socket will become invalid and no longer have any functions. As a result, this type of smart socket cannot completely and effectively record changes in power-related parameters during the fault occurrence process, which is inconvenient for subsequent anal...
