Embodiment Construction

[0070] The present invention proposes a multi-frequency ad hoc network and a communication method suitable for a power line carrier communication system, which supports uplink random access, active reporting, two-way interaction, intelligent copying and other services. The invention utilizes single-frequency equipment to realize multi-frequency networking, selects the optimal operating frequency according to the actual channel conditions of the nodes, increases the number of slave stations directly communicating with the master station, reduces the number of relays and the number of hops, and improves the network terminal to end-to-end latency and throughput performance.

[0071] The single-frequency device means that the device has only one receiving / transmitting module, and can only receive / transmit in one frequency at the same time, and the device can adjust the central frequency point and bandwidth of the receiving / transmitting frequency at different times.

[0072] Such a...

Abstract

The invention provides a multi-frequency self-networking and communication method suitable for a power line carrier communication system. The method includes the following steps that: the power line carrier communication system is initialized, and the working frequency of the system is configured; a node having master station functions searches a power line carrier communication network and decides whether to build a new network through judgment according to a search result; a networking mode is enabled, a multi-frequency multi-hop power line carrier communication network is built; and networking is terminated, a conventional communication mode is enabled, and multi-frequency multi-hop data communication between a master station and a slave station can be realized. The multi-frequency self-networking and communication method suitable for the power line carrier communication system supports multi-frequency multi-hop communication, is of great significance for the improvement of the reliability of the power line carrier communication system, the improvement of node access rate and the expansion of network coverage range, supports intelligent electricity utilization business such as active reporting and bilateral interaction, is applicable to the future development direction of the power line carrier communication network, and has a wide application prospect.

Description

Technical field: [0001] The invention relates to a multi-frequency ad hoc network and a communication method, in particular to a multi-frequency ad hoc network and a communication method suitable for a power line carrier communication system. Background technique [0002] Due to the different link lengths, load conditions, and network branch conditions in different geographical locations, the channel attenuation of the power line carrier communication network shows frequency selectivity. In addition, the noise distribution of the power line carrier communication network is also different, and the noise also shows frequency selectivity. Frequency selective attenuation and frequency selective noise directly result in certain frequencies not being used properly in certain areas. In other words, the power line carrier communication network has the characteristics of frequency selectivity, and the optimal communication frequency of different links is different. [0003] In the ...
