The invention relates to the technical field of electronics, in particular to a three-phase motor water pump allowing wireless remote measure and control of soil humidity. The water pump comprises a soil humidity sensor, a soil humidity measuring bridge, a low frequency crystal oscillator, a differential amplifier, a detector, a power amplifier, 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 water pump achieves full automatic crop field irrigation control through oil humidity sensing, crop field moisture remote measure and control and wireless transmitting and receiving, enables the crops in the crop field far away from a water source, insufficient in water source and with uneven terrain 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 alternating current 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 that soil humidity can meet the crop growth requirement.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a wireless telemetry and remote control soil humidity three-phase motor water pump. 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. Especially in arid and barren areas with little rainfall, the water source is insufficient or far away from the water source, or the terrain is uneven and the farmland is inconvenient for irrigation, which affects agricultural production. Contents of the invention [0003] The purpose of the present invention is to provide a wireless telemetry and remote control soil humidity three-phase motor water pump for measuring farmland soil moisture and drying information wirelessly, electromagnetic wave space transmission to a wireless receiver with water so...
