[Abstract]:In order to monitor the key environmental parameters of grape and reduce the labor intensity of agronomists, a grape cultivation monitoring system based on layered WSN network and Wi-Fi technology was proposed. The acquisition node is constructed with CC2530 wireless emission chip as the core, and the corresponding software and hardware design is carried out to complete the real-time acquisition of air temperature and humidity, soil temperature and humidity and so on. In order to solve the problem of node location, combined with the requirement of grape cultivation, the network structure based on virtual cell was adopted, the cell cluster head selection mechanism was optimized, the multi-hop transmission was completed by using hierarchical method, and the automatic retransmission error correction mechanism was adopted. Compared with the typical LEACH-C algorithm, the network node mortality of the improved algorithm is reduced by about 23%. Combined with the Wi-Fi technology of multi-point access, the monitoring range of the system is extended. The upper computer monitoring system can operate intuitively, and can monitor the change of parameters in the process of grape growth in real time, and automatically alarm and instruct the operation according to the expert experience database. The system is stable and reliable and can meet the needs of planting management.
