Power cord intelligent plug

Abstract

The invention relates to the field of utility power monitoring and control, and relates to a power cord intelligent plug for monitoring and controlling utility power. Compared with the prior art or application, the invention solves the problems in terms of intellectualization and miniaturization of a power cord plug, and has the advantages of simple structure, convenient assembly, low cost and easy mass production. The invention designs and integrates the following components in hardware: relay and drive components, voltage measuring components, current measuring components, electric leakage measuring components, ungrounded wire and null-live line reverse connection monitoring components, isolated inductive button components, and one of LCD displays, WIFI and ISM wireless networking modules. The invention designs the following functions and controls in software: adjustable upper and lower limit thresholds of the safety voltage, adjustable upper and lower limit thresholds of the safety current, adjustable upper limit threshold of the safety electric leakage, the four-period timing on / off, the alternating current frequency measurement, the volatile power consumption metering, local human-computer interaction control, and remote control commands, and integrates the HEXPLUS IoT communication protocol of the applicant's independent intellectual property rights.

Description

technical field [0001] The invention relates to the field of mains power monitoring and control, in particular to a power cord smart plug for monitoring and controlling the mains power. Background technique [0002] The vast majority of ordinary electronic and electrical equipment for civilian use needs to use mains power (mainland China's mains power specification is 50Hz AC 220V). The method of connecting to the mains power is usually to insert a power cord with a plug into the socket. The plugs and sockets meet the standards of their respective countries. Standard, so any plug can be inserted into any socket, the ordinary plug only plays the role of plugging in and pulling out the power, and the leakage protection plug can also play the role of automatically disconnecting the mains due to leakage, usually used for washing machines, water heaters and the like Electrical equipment that is closely related to water and gas, but compared with ordinary plugs, leakage protection...
