Communication device and method of NFC-based low-power-consumption irrigation facility

Abstract

The invention discloses a communication device and method of an NFC-based low-power-consumption irrigation facility. The communication device comprises a master control MCU, a magnetic driving valve and a voltage stabilizing and boosting circuit and further comprises an NFC storage unit for receiving regulation and control parameter update, wherein the master control MCU is respectively connected with the magnetic driving valve and the voltage stabilizing and boosting circuit, the NFC storage unit performs internal data transmission with the master control MCU through an internally-integrated I2C communication interface and is connected with an external sensing antenna through an internally-integrated RF interface. When the communication device and method performs the irrigation regulation and control parameter update, the NFC storage unit in the device, namely a target device is in a radio frequency card simulation mode, a radio frequency field is not required to be produced, a load modulation technology is adopted to return irrigation parameters to an NFC initiation device, meanwhile irrigation parameter writing-in can be quickly performed through the NFC initiation device, and set timely update of the irrigation parameters is achieved. Therefore, when an energy capture function of the NFC storage unit is in a working state, the NFC storage unit can provide redundant caught energy for work of other devices.

Description

technical field [0001] The invention relates to the field of agricultural intelligent irrigation, and the main content is an irrigation facility communication device and method based on NFC (Near Field Communication) low power consumption. Background technique [0002] The low-power irrigation control device has the characteristics of small size and low power consumption, and is suitable for flexible deployment and management in orchards with complex terrain and harsh environments. After adding an intelligent irrigation control device to the traditional irrigation system, it can realize regular and quantitative drip irrigation for fruit trees, which not only saves agricultural irrigation water consumption, but also improves the utilization rate of agricultural irrigation water. [0003] At present, commonly used intelligent irrigation control devices are usually composed of single-chip microcomputers, power circuits, human-computer interaction interfaces, AC / DC solenoid valv...

AI Technical Summary

Problems solved by technology

The process of setting irrigation control parameters using buttons or touch screen will generate instantaneous power consumption, increase the number of times the buttons are used, and reduce the service life of the device. A common solution is the irrigation parameter programmer based on the infrared transceiver module. This solution not only generates The power consumption is high, on the other hand, it is also necessary to configure a special dustproof protective cover for the infrared receiving head, which is not the ideal solution
