Embodiment 1

[0020] Such as Figure 1~3 As shown, a multi-channel soil moisture acquisition system and method based on AT89C52, when the acquisition task needs to be performed, the operator powers on and initializes the system, presses the acquisition button 4 on the outer frame 1 of the acquisition system, and the single-chip microcomputer passes the query Or the interrupt mode judges that data acquisition is needed, then the soil moisture sensor 7 of the front-end eight channels will collect the soil moisture analog signal, after being converted into a corresponding digital signal by the ADC0809 analog-to-digital converter, it will be passed to the acquisition control circuit, and the single-chip microcomputer will The obtained data is processed and saved. After the external device is connected to the mobile storage device through the USB transmission interface 8, click the save button 6 to save the data to the storage device, which is convenient for processing and analyzing the data in t...

Abstract

The invention discloses a multi-channel soil moisture content collecting system and method based on an AT89C52. By combining the sensor technology and the single-chip microcomputer technology, the soil moisture contents of multiple points in an area are effectively collected; the collecting system comprises a power supply part, a soil moisture content sensor, an ADC part, an LCD part, a collecting button part, a display button part, a storage button part and a collecting control circuit. The collecting control circuit is electrically connected with the soil moisture content sensor, the ADC part, the LCD part, the collecting button part, the display button part and the storage button part. The power supply part supplies power to the collecting system. The system is simple in design, small in size, convenient to carry and quite suitable for collecting soil moisture contents of multiple points outdoors.

Description

technical field [0001] The invention belongs to the technical field of soil moisture data collection, in particular to a multi-channel soil moisture collection system based on AT89C52. Background technique [0002] The present invention originates from the actual need to measure the soil moisture required for crop growth in the experiment. Soil moisture is the water content of the soil, which is not only an important factor for crop growth, but also an indicator of the degree of soil drought in the region. The moisture content of crops plays an important guiding role in the next step of precise irrigation of crops. The traditional soil moisture collection method uses methods such as drying, which not only destroys the integrity of the soil, but also has cumbersome operations and poor efficiency, which cannot meet the current needs for rapid and portable soil moisture detection. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention p...
