Embodiment Construction

[0041] The present invention will be further described below in conjunction with accompanying drawing.

[0042] Such as figure 1 As shown, the power dual-mode communication architecture based on the IEEE1901.1 communication standard of the present invention is composed of a broadband carrier communication (HPLC) chip, a software radio frequency module (or chip), and a power line drive circuit. HPLC chip and power line drive circuit constitute the traditional wired broadband power carrier communication. HPLC baseband chip and software radio frequency module (or chip) constitute the wireless broadband communication.

[0043] The HPLC baseband chip is a chip based on the IEEE1901.1 standard. Since the IEEE1901.1 standard adopts the OFDM communication method, it requires a high frequency error (<0.5%) between transceivers. If the center frequency of the transceiver radio frequency carrier is 500MHz, then the crystal oscillator stability of the system is required to be better th...

Abstract

The invention discloses a power dual-mode communication method based on an IEEE1901.1 communication standard. An HPLC chip and a power line drive circuit form the traditional wired broadband power line carrier communication, and an HPLC baseband chip and a software radio frequency module form the wireless broadband communication. The method is characterized by being realized through the frequencysynchronization and the intermediate frequency signal processing. the method fully utilizes the advantages of the IEEE1901.1 in the electric power communication and gives full play to the advantages of the wireless communication, so that an algorithm of wireless communication based on IEEE1901.1 is provided, the IEEE1901.1 can work in a power line carrier wave wired communication mode and the wireless communication in a state grid special frequency band, and can transmit and receive at any specified point frequency in a power grid communication frequency band, and the communication in two modes of the same standard is realized. By the method, the power broadband communication has the advantages of long communication distance, low module cost, low power consumption, wide application range and the like.

Description

technical field [0001] The invention relates to a dual-mode communication method based on the IEEE1901.1 low-voltage power line broadband carrier communication protocol, wherein the dual mode includes low-voltage power line broadband carrier communication and wireless broadband carrier communication, and the two modes use a complete Q / GDW 11612 physical layer , link layer and application layer. [0002] technical background [0003] IEEE1901.1 "Technical Standard for Intermediate Frequency (Below 12MHz) Power Line Carrier Communication for Smart Grid Applications" is a data link layer technology based on the State Grid Corporation of China Q / GDW 11612 "Technical Specification for Interconnection and Interoperability of Low-Voltage Power Line Broadband Carrier Communication" specification. The IEEE 1901.1 standard builds a high-bandwidth, high-reliability, low-latency, and low-cost power line communication network to support various application scenarios such as remote automa...
