Abstract

The invention relates to the technical field of electronics, in particular to a solar power supply remote measure and control three-phase motor full automatic irrigation water pump. The water pump comprises a soil humidity sensor, a wireless transmitter, a water source detection sensor, a water source optical coupler control switch, a wireless receiver and a three-phase motor water pump. The solar power supply remote measure and control soil humidity water pump achieves full automatic irrigation control in the crop field wherein an altering current power supply is inconvenient to lay, especially in the crop field away from a water source, insufficient in water source and with uneven terrain, enables different crops to be in the optimum growth state, and greatly improves the agriculture planting production level. The soil humidity sensor and the water source detection sensor adopt electrode sine wave sensing, and effectively prevent electrolytic etching and prolong service life. The water pump has the advantages of wireless receiving/transmitting crystal oscillators, high stable frequency remote measure and control, pulse coding, high coding capacity, high anti-interference and stable reliable operation in adjacent crop fields without interference. The water pump is widely applied to crop field irrigation to ensure soil humidity and meet the crop growth requirement.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a fully automatic irrigation water pump of a three-phase motor with solar power remote measurement and remote control. Background technique [0002] The soil where plants grow needs to maintain a certain humidity. Manually controlling soil humidity is not accurate and requires a lot of labor, which is not suitable for modern agricultural production requirements. In particular, the water source is insufficient or far away from the water source in the arid and poor areas with little rain, or the terrain is uneven, and the AC power grid is inconvenient to lay, which affects agricultural production. Contents of the invention [0003] The purpose of the present invention is to provide a farmland where the AC power grid is inconvenient to lay, measure the soil wetness and dryness information wirelessly, transmit the electromagnetic wave space to the wireless receiver with the wat...
