Abstract The improvement of the sensor power supply system in intelligent greenhouse is a research hotspot at present. In intelligent greenhouse environment monitoring demand is high, the traditional cable power supply volume is big, poor security and inconvenient to the characteristics of the paper by using the principle of the wireless power supply, design a kind of orthogonal magnetic field, the Transmitting coil and Repeating coil to receive the mutual inductance coil superposition to satisfy the sensors in the power supply requirements of different spatial location, and greatly reduces the power supply equipment covers an area of. The theoretical circuit diagram is given and the theoretical analysis and formula derivation of uniform magnetic field are performed. Mathcad was employed to simulation analysis of Receiving coils in different states, and Maxwell was used for comparison of hypnotic field cloud images. At the same time, the influence of different relative positions on the receiving power of wireless power transmission system is tested and discussed, and the method to improve the wireless power supply transmission efficiency of smart greenhouse sensor is explored. Finally, the feasibility of the system is verified by simulation and experiment.
