A power connection device

Abstract

A power supply connection device, including: an electric connector, a shell connected to the electric connector, and at least one socket disposed on the shell, and also including: a modulation / demodulation module, a control module and a data acquisition module, wherein the control module and the data acquisition module are separately connected to the at least one socket. The control module is used for controlling the ON or OFF of the socket according to a control signal. The data acquisition module is used for acquiring the ON or OFF state of the socket and operational parameters. The modulation / demodulation module is used for receiving a signal transmitted via an electric power line, extracting the control signal from the received signal and transmitting same to the control module, and receiving the data acquired by the data acquisition module, modulating the data acquired by the data acquisition module and then transmitting same to the electric power line. The power supply connection device provided in the present application can not only perform remote monitoring on the state of the power supply connection device, but can also perform remote control on the power supply connection device.

Description

technical field [0001] The present application relates to the technical field of electrical appliances, in particular to a power supply connection device. Background technique [0002] Existing home automation network, data transmission can be carried out through wireless network, wired network and wireless network. [0003] Wireless networks generally use radio frequency transceivers (Radio Frequency Transceiver) to form a network with power supply equipment to monitor or control power supply equipment. The reliability of the connection transmission control signal will be reduced, resulting in delays and even system instability. [0004] Wired networks can lay special data lines between devices, for example, existing broadband network data lines, which require special planning and design during design, and require separate wiring during implementation, resulting in high costs, especially The project of transforming the existing family house is very difficult and even impo...

Problems solved by technology

[0003] Wireless networks generally use radio frequency transceivers (Radio Frequency Transceiver) to form a network with power supply equipment to monitor or control power supply equipment. The reliability of the connection transmission control signal will be reduced, resulting in delays and even system instability

[0004] Wired networks can lay special data lines between devices, for example, existing broadband network data lines, which require special planning and design during design, and require separate wiring during implementation, resulting in high costs, especially The renovation project for existing family houses is very difficult and even impossible

In addition, the wired network can also form a network through the power line between devices, that is, use power line communication, so that as long as the device is connected to the power supply, no separate wiring is required, but the existing home automation network using power line communication, one is to connect the power line As a broadband network, the network is only connected to the Internet; the other usually only uses the main control device to control the power consumption of the controlled device, such as a computer connected to the main control device, and a printer coupled to the computer, Peripherals such as scanners and stereos are connected to the controlled device, so that when the user powers off the computer, the master control device will control the controlled device to power off, that is, other peripherals will also be powered off at the same time

[0005] Through the research of the prior art, the inventor found that: compared with the radio frequency signal, although the home automation network using the power line communication does not need separate wiring, and the control signals will not interfere with each other, the reliability is high, but it can only realize the power supply The power supply mode of the equipment is controlled, that is, power-on or power-off control, but the status of each power supply equipment cannot be monitored, which cannot meet the needs of home automation
