Abstract

The invention relates to a wireless network terminal node with a function of automatic water-saving irrigation and application thereof. The wireless network terminal node comprises a ZigBee module, a temperature and humidity sensor, a water supply branch electromagnetic valve, a solar cell panel and a rechargeable battery, wherein the solar cell panel is electrically connected with the rechargeable battery; the rechargeable battery is electrically connected with the ZigBee module, the temperature and humidity sensor and the water supply branch electromagnetic valve respectively; and the ZigBee module is electrically connected with the temperature and humidity sensor and the water supply branch electromagnetic valve respectively. Detection on soil temperature and humidity and corresponding control on the water supply branch electromagnetic valve can be completed by means of the wireless network terminal node, and an irrigation control system is formed by the wireless network terminal node with master control equipment, so thatunattended automatic water-saving irrigation control for crops at different growing stages can be realized. The wireless network terminal node has the characteristics of high system layout flexibility, convenience in operation management, relatively low cost and the like, and is especially suitable for automatic water-saving irrigation control of large-area fields.

Description

technical field [0001] The invention relates to a wireless network terminal node for automatic water-saving irrigation and an application thereof, belonging to the technical field of water-saving irrigation. Background technique [0002] Today, the increasing scarcity of fresh water resources and the gradual increase in labor costs have made automatic water-saving irrigation technology an important direction for the development of water irrigation for modern agriculture, forestry and animal husbandry. Unattended automatic water-saving irrigation equipment needs to meet many basic functional requirements including: soil temperature and humidity data collection, independent control of water supply branch on-off, water supply control, etc. For the automatic water-saving irrigation control of large-scale fields, due to the large number of water supply branches and soil temperature and humidity test points, if long-distance connections are used for power supply and data collectio...
