Energy-saving management method and system based on power line carrier

Abstract

The invention relates to an energy-saving management method and system based on a power line carrier. The method comprises the steps as follows: an intelligent power control terminal transmits a control command and receives state information; the control command and the state information are transmitted by the power line carrier; and an intelligent power terminal device actuates and returns the state information after receiving the control command. The system comprises the intelligent power control terminal, a modulator-demodulator, and the intelligent power terminal device. The intelligent power control terminal is electrically connected with the modulator-demodulator, and is used for sending the control command to an intelligent power terminal and receiving the state information returned by the intelligent power terminal; the modulator-demodulator is used for receiving and sending the power line carrier; and the intelligent power terminal device receives and actuates the control command of the intelligent power control terminal, and returns the state information according to the control command simultaneously. The invention can implement communications by using an existing power distribution network and does not need rewiring; moreover, power line networks are broadly distributed and are convenient to access; and the modulator-demodulator is used for data sending and receiving, which is quick and stable.

Description

technical field [0001] The invention relates to the field of electric power, in particular to an energy-saving management method and system based on power line carrier. Background technique [0002] In recent years, with the development of the economy, the advancement of science and technology, and the advent of the Internet age, people's demand for electricity has reached a new level. Building control systems, various security and fire protection systems, network equipment, a large number of applications of computers, and the introduction of various new household appliances have greatly increased people's demand for electricity. Can not be ignored. [0003] Therefore, many energy-saving systems and products have emerged, but because of the need for data exchange between various devices, it is necessary to set up communication lines between terminals. If new lines are set up, the project will be complicated and huge. Although existing Carrier communication is performed on ...

[0003] Therefore, many energy-saving systems and products have emerged, but because of the need for data exchange between various devices, it is necessary to set up communication lines between terminals. If new lines are set up, the project will be complicated and huge. Although existing Carrier communication is carried out on the power line, but the existing technology lacks the corresponding intelligent power supply control terminal, even if the user has an intelligent power supply terminal device, the corresponding energy-saving management operation cannot be performed
