Wireless sensor network-based greenhouse group control system and control method thereof

Abstract

The invention discloses a wireless sensor network-based greenhouse group control system and a control method thereof. Each greenhouse is provided with a plurality of wireless sensor nodes and a cluster head node for acquiring environmental factors of the greenhouses according to needs, wherein the wireless sensor nodes and the cluster head nodes autonomously form wireless sensor networks by wireless communication; the wireless sensor nodes transmit monitoring data to the corresponding cluster head nodes in a multi-hop way; the cluster head nodes transmit the data to a gateway node which uploads the data to a communication server; the communication server performs two-way communication with a control computer; and the control computer makes corresponding guidance schemes according to the data monitored by the wireless sensor networks in real time, and synchronously transmits control instructions to the wireless sensor networks according to the guidance schemes. In the system and the method, the real-time data monitored by each sensor node in the greenhouses can be timely and accurately acquired, and the control instructions can be fast transmitted to the sensor nodes after specific production guidance is made or early-warning setting is performed according to the monitoring data.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a greenhouse group wireless sensor network control system and a control method thereof. Background technique [0002] A greenhouse is a facility that uses artificial buildings to implement high-yield and efficient modern agricultural production methods through adjustable technical means. It is a place to change the external environment for plant growth, create the best conditions for plant growth and development, and avoid the impact of external four seasons and harsh climate on its growth and development. Solar greenhouse is a large-scale and rapid development of facility agriculture after my country's reform and opening up, and has become an important part of the adjustment of agricultural industry structure. At present, greenhouse environment control mainly includes computer control systems based on single-chip microcomputers, industrial control computers or p...
