Pig farm environment monitoring method based on patrol car and address borrowing routing algorithm

Abstract

The invention discloses a pig farm environment monitoring method based on a patrol car and an address borrowing routing algorithm. First, a pig farm environment monitoring system based on a patrol car and an address borrowing routing algorithm is built, comprising a pig farm wireless sensor network with mobile coordinator nodes constructed based on a ZigBee wireless communication technology, a pig farm embedded field control center, and a user remote control center. Second, in view of isolated network points caused by limited transmission range of the ZigBee protocol, a new network address borrowing routing algorithm based on two-hop neighbors is adopted, the existing address borrowing routing algorithm is optimized, the address borrowing range of a father node is set to two-hop neighbor nodes, and addresses are borrowed from descendant nodes of the same branch first. On one hand, the problem of isolated network points is relieved, the network access rate of network nodes is improved, and the networking time and energy loss are reduced. On the other hand, efficient network access of isolated network nodes under the pig farm environment monitoring system taking coordinators as mobile nodes is realized.

Description

technical field [0001] The invention relates to embedded technology and wireless sensor network technology, in particular to a pig farm environment method with a patrol car and an address-by-address routing algorithm. Background technique [0002] The domestic pig industry is in a stage of rapid development, and is developing towards large-scale and modernization, and responds to increasing production costs and fluctuating market conditions with efficient production. However, for intelligent farming, there are still problems such as low automation level of breeding equipment, high labor intensity, poor environmental equipment, lack of intelligence, inability to meet the needs of information-based farming, and low production efficiency. [0003] The pig farm environmental monitoring system is based on wireless sensor networks to monitor various environmental indicators in real time and intelligently control various equipment. Applying wireless sensor network to pig environme...

Problems solved by technology

Yao Yukun and others proposed an efficient address allocation algorithm based on borrowed addresses. The borrowing range of routing orphan nodes is first selected as the same branch node to improve the detour problem, but the borrowing range is small, and the success rate of nodes joining the network is reduced.
