Wireless communication Ad-Hoc Network-based intelligent agricultural system

Abstract

The invention discloses a wireless communication Ad-Hoc Network-based intelligent agricultural system, comprising a center coordinator, field nodes, a strip field pump room control node, and Ad-Hoc modules; the strip field pump room control node and the plurality of field nodes form a group of unit strip field and are respectively and internally provided with the Ad-Hoc modules; each Ad-Hoc module consists of a singlechip and a radiofrequency chip; the field nodes are internally provided with independent power sources; the strip field pump room control node is directly connected with mains supply. Network connection is performed by adopting different nodes in a relay or wireless connection manner, mounting is convenient, communication is stable, a communication distance is far enough, and a communication link is different from place to place, and is more reasonable; the system uses a nationally specified metering frequency 490M and opens 16 channels, a whole communication module is in low power, is not easily distributed and can stably transmit; a working current is small, a dormant current is low and the system is very energy-saving and electricity-saving.

Description

technical field [0001] The present invention relates to the field of intelligent agriculture, in particular to an intelligent agricultural system based on wireless communication ad hoc network. Background technique [0002] In order to alleviate the increasingly tense situation of agricultural water use, the country has gradually increased the construction of water-saving irrigation in recent years, and several "agricultural intelligent water-saving irrigation systems" have been launched at home and abroad. The general situation mainly includes infrastructure control and data collection, statistics, Analyze two major aspects to carry out research and exploration. In terms of infrastructure control, the communication control system is the current sampling cable device in China. The cost of use is high. If you encounter roads or water conservancy facilities, it is extremely difficult to install a wireless system communication system that uses sampling and transparent transmis...

Problems solved by technology

[0005] In order to solve this problem, micro-power wireless communication technology is included in the latest series of standards of the State Grid Corporation of China's power consumption information collection system. In 2005, the Radio Commission's "Technical Requirements for Micro-power (Short-range) Radio Equipment" The document stipulates that 470MHz~510MHz is the dedicated frequency band for civil radio metering instruments, but the allowable transmission power is only 50mW. The communication distance is too short to meet the needs of meter reading applications. The existing technology can only increase the transmission distance through relay transmission. When it is used in a large area, the selection of relay nodes is impossible, and it still needs to be realized by manual settings.
