Embodiment Construction

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the home grid of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] In daily life, basic electrical appliances must be connected to the power line of the home grid. By adding control components, the existing power line can be used to realize smart home management; Basic electrical appliances must first be equipped with wireless connection devices to achieve intelligent management, which increases the cost and makes it more difficult. It can be seen that the wired method is more suitable for realizing the intelligent management of basic electrical appliances than the wireless method.

[0033] The invention provides a smart home grid with a wired broadcasting function, and the switch control signal is set to be transmitted on the power line that originally can only tr...

Abstract

The invention belongs to the power transmission and transformation technical field and relates to a household power grid. The household power grid comprises a power line, a plurality of electrical appliances connected with the power line and controllers corresponding to the electrical appliances; the household power grid further comprises a field control unit and a central control unit; the field control unit comprises a modulator connected with the controllers and a demodulator connected with the electrical appliances, wherein the modulator is used for generating and transmitting switch control signals, and the demodulator is used for receiving and extracting electrical appliance control signals; the central control unit is connected with the modulator and demodulator and is used for receiving the switch control signals of the modulator, generating corresponding on-off control signals, and sending the on-off control signals to the demodulator; the demodulator receives the on-off control signals and adopts the same as the electrical appliance control signals. The household power grid has the advantages of simple and easily-editable control logic, high security, low cost and so on.

Description

technical field [0001] The invention belongs to the technical field of power transmission and transformation, and in particular relates to a household power grid. Background technique [0002] Power transmission and transformation technology is an important technology for power plants to generate electricity for users, and provides an important foundation for human civilization. At present, the entry standard of the home grid is 220V / 50Hz or 110V / 60Hz. Due to the complexity of the building or community grid, the entry voltage needs to be filtered and isolated to avoid interfering with the operation of the home grid and ensure that the entry voltage and frequency meet the requirements. [0003] With the wide application of electronic technology in real life, people are more and more aware of the various conveniences that electronic products bring to life. A variety of electrical appliances are involved in the home grid, and most of them are devices that involve switching, su...
