Embodiment Construction

[0015] like Figure 1-5 Shown, the soil water content tester based on embedded system provided by the present invention comprises host computer (such as figure 1 shown) and lower computer (such as image 3 shown). Please refer to figure 1 , The upper computer includes a minimum S3C44B0X system 13 for mutual communication, a color LCD display and a touch screen 16, a touch screen controller 15, an EEPROM memory 12, a wireless communication module 11, and a network controller such as RTL8019. The S3C44B0X minimum system 13 only integrates 8KB of RAM without integrating FLASH-ROM and SDRAM. The present invention expands the FLASH and RAM outside the S3C44B0X minimum system 13 to form a basic minimum system, and burns the firmware in it. program. The color LCD display 16 with a touch screen is a four-wire resistive touch screen, and the ADS7843 is selected as the touch screen controller 15 . The wireless communication module 11 must be consistent with the wireless communicati...

Abstract

The invention provides a soil moisture content monitoring instrument based on an embedded system, which comprises an AVR series Megal 16 singlechip, an arch electrode couple and a soil moisture sensor comprising signal conditioning circuits; a Samsung ARM7 S3C44BOX chip, peripheral circuits and an epigynous machine controlling system which comprises a liquid crystal monitor with a touch screen; a wireless communication module; and a power supplying system which comprises a solar panel and a storage battery. The singlechip gathers directly the soil electrical conductivity data which are measured by the soil moisture sensor and transferred into soil moisture data inside the singlechip; at the same time, through the wireless communication module and according to the requirements of the epigynous machine, the measured data are transmitted in real time or fixed time, or the controlling orders of the epigynous machine are received.

Description

technical field [0001] The invention relates to a soil moisture monitoring device, which is especially suitable for hills, mountains or farmlands with large areas where the soil moisture changes greatly, and is used for monitoring soil moisture. Background technique [0002] The modernization of China's agriculture and rural areas is entering a new period of modernization driven by informatization. After more than 20 years of practical exploration and prediction of future development trends, it is shown that the development trend of China's agriculture is from agricultural modernization to agricultural informatization, from modern agriculture to Information Agriculture. Informatization of agricultural production management, informatization of agricultural science and technology, informatization of agricultural management and informatization of agricultural resources and environment are important components of informatization agriculture. The transformation from traditional a...
