Intelligent management method of solar sprinkler

Abstract

The invention discloses an intelligent management method of a solar sprinkler. The method comprises an intelligent sprinkling management strategy and a solar lithium battery charge management strategy, wherein the intelligent sprinkling management strategy is comprehensively formulated according to a water demand, heat resistance and a disease law of a lawn; the water demand is obtained according to a change of appearance quality of the lawn under different water-holding capacities; the heat resistance is obtained from the change of the seepage conductivity outside the lawn before and after the lawn is sprayed; the disease law means that irrigating at night can aggravate disease and insect disaster of the lawn, and the solar lithium battery charge management strategy means a process of carrying out intelligent charging of constant-pressure, constant-flow and trickle charging modes on a lithium battery by a power management chip according to the detected electric quantity. According to the intelligent management method, intelligent control of the solar sprinkler can be achieved, communication between a PC (personal computer) and each irrigating node can be achieved by a CAN (controller area network) bus, and distributed network management is achieved. Therefore, a normal growth requirement of the lawn is met; waste of water resource is reduced, and an intelligent level of the sprinkler is improved at the same time.

Description

technical field [0001] The invention relates to the field of intelligent irrigation, in particular to an intelligent management method of a solar sprinkler irrigation device. Background technique [0002] The total amount of water resources in my country is 2.8 trillion square kilometers, with a per capita share of about 2,200 cubic meters, which is only 25% of the world's per capita share. Problems such as uneven distribution of water resources in time and space, water pollution, and imbalances in water ecosystems have exacerbated the current supply and demand of water resources. contradiction. Therefore, for our country, the rational planning and utilization of water resources is imminent. Scientific and rational use of limited water resources, effective control of irrigation water consumption, timely supply of water according to natural precipitation, reservoir water storage, exploitable groundwater and crop growth needs are necessary scientific means to promote water con...

AI Technical Summary

Problems solved by technology

[0004] At present, lawns generally still use artificial sprinkler irrigation or solenoid valve timing sprinkler irrigation, and there are a small amount of research on intelligent sprinkler irrigation, but only simple management of lawns has been realized, and there is no scientific, reasonable and perfect intelligent management method applied to practice. , resulting in a serious waste of water resources

Some sprinkler irrigation devices with relatively advanced technology use wireless sensor technology or GPRS technology for remote control, which has no advantage for general lawn sprinkler irrigation.
