Control method for farmland irrigation and fertilization

Abstract

The invention discloses a control method for farmland irrigation and fertilization. The method comprises the following steps of 1) establishing communication connection in which wireless communication connection is established between an onsite control system laid in farmland to be irrigated and a network coordination controller via the ZigBee wireless communication network, and wireless communication connection is also established between a monitoring center server laid in a remote monitoring center and the network coordination controller via the GSM network; 2) sending parameter collection commands in which the monitoring center server sends a soil environment detection command and a water detection command to a core processor; 3) collecting and processing onsite data; 4) transmitting data wirelessly and remotely; 5) raising alarm against faults and sending a fertilization and irrigation command; and 6) executing a control command. According to the invention, the ZigBee wireless communication technology is applied to the control method, the whole control system is thus characterized by high robustness, low power consumption and low cost, and the control method can be widely popularized and used.

Description

technical field [0001] The invention relates to a control method, in particular to a control method for irrigation and fertilization of farmland. Background technique [0002] my country is a large agricultural country. Improving the efficiency of agricultural water use, developing water-saving agriculture, and actively promoting water-saving irrigation and fertilization technologies are important strategies for ensuring national water security, food security and ecological security, and promoting sustainable development of agriculture and rural economy. status and role. [0003] Traditional irrigation schemes do not yet have intelligent self-service functions. Pre-set operations are often implemented through pre-stored irrigation and fertilization strategies. During the irrigation process, only the switch and timing of irrigation equipment can be controlled; and existing irrigation methods require professional knowledge. Knowledgeable management personnel monitor in real ti...

[0003] Traditional irrigation schemes do not yet have intelligent self-service functions. Pre-set operations are often implemented through pre-stored irrigation and fertilization strategies. During the irrigation process, only the switch and timing of irrigation equipment can be controlled; and existing irrigation methods require professional knowledge. Knowledgeable management personnel monitor in real time and respond to equipment failures or abnormal phenomena during irrigation and fertilization in a timely manner, which wastes human resources and affects irrigation efficiency
