Technical Field

[0002] With the rapid development of precision agriculture and smart agriculture, the demand for real-time, efficient, and multi-dimensional environmental data monitoring in agricultural production is increasing. Traditional agricultural management relies on manual observation and experience-based judgment, resulting in low efficiency, inaccurate data, and high labor costs. In recent years, the development of the Internet of Things, sensor technology, and edge computing has driven the upgrading of agricultural monitoring equipment. For example, fixed monitoring stations are used to collect farmland data through devices such as temperature and humidity sensors, soil nutrient analyzers, and spectrometers, combined with wireless transmission technology to achieve remote monitoring.

[0003] However, fixed monitoring stations still have many limitations in practical applications. The construction of fixed monitoring stations requires pre-drilling trenches and laying cables, as well as deploying power supply and communication facilities, which is a complex process with high construction costs. Fixed monitoring stations have poor flexibility and are difficult to adapt to scattered small-scale farmland or complex terrain, and the trenching process can damage the farmland structure.

The mounting mechanism 4 is equipped with multiple ground pins 4. 1. A plurality of through holes 42, wherein each ground pin 41 is located in a corresponding through hole 42 and can move relative to the ground pin 41 along the axial direction of the through hole 42. The bottom end of the ground pin 41 is a pointed end and the top end is an expanded end. The size of the expanded end is larger than the size of the through hole 42. When fixed, the pointed end of the ground pin 41 passes through the through hole 42 and moves downward along the axial direction of the through hole 42 to insert into the soil until the expanded end contacts the top surface of the through hole 42, thus fixing the ground pin 41 in the soil. The expanded end of the ground pin 41 is stuck outside the through hole 42 to fix the installation mechanism.

[0022] The monitoring mechanism 1 has a sleeve 11 fixed at its bottom, which is fitted onto the top of the support rod 2. The side wall of the sleeve 11 has a pair of threaded through holes 12 symmetrically arranged.

[0031] For general soil and paddy fields, the needle 41 can be inserted. The assembly of the support rod 3 and the installation mechanism 4 of this utility model can be directly inserted into the soil for fixation.
