Description

Technical Field

[0001] The present invention relates to the technical field of surveying and mapping equipment, in particular to a farmland fixed-point surveying and mapping equipment. Background Art

[0002] As we all know, in the land planning in the agricultural field, the fixed-point surveying and mapping equipment of cultivated land plays a key role. When carrying out the basic construction planning of farmland, it can accurately map the current status of the cultivated land, including the size, shape, boundaries, etc. of the plot, and provide accurate data support for the reasonable planning of irrigation channels, field roads and other infrastructure. In land consolidation projects, it is used to determine the scope and elevation changes of the land leveling area in order to accurately calculate the earthwork volume. For precision agriculture, the equipment can locate soil fertility monitoring points, pest and disease monitoring points, etc., to help farmers accurately apply fertilizers and pesticides.

[0003] After searching, a Chinese patent discloses a farmland fixed-point surveying and mapping equipment, and its application publication number is CN118376216B. This patent belongs to the technical field of surveying and mapping equipment, including a containing tube, a surveying ruler, a rotating shaft, a mounting tube, a movable tube, a support rod, a sliding rod, a connecting base plate, and a positioning and fixing needle. The mounting tube is fixedly mounted on the surface of the side plate, and the connecting base plate is mounted on one end of the mounting tube. The movable tube is rotatably connected to a plurality of the support rods, and the connecting base plate is rotatably connected to a plurality of the sliding rods. An air bag is installed at one end of the support rod away from the movable tube, and a positioning and fixing needle is fixedly installed on a side of the connecting base plate away from the mounting tube. The support rod and the sliding rod are provided to support and secondary fix the surveying and mapping equipment. After the support rod contacts the water surface during rotation, the air bag is inflated, and the fixing effect is further enhanced by squeezing the air bag, thereby avoiding the displacement of the positioning and fixing needle and the tipping over of the positioning and fixing needle when the surveying ruler is pulled.

[0004] Surveying and mapping equipment is often used in fixed-point surveying of cultivated land. The problems with the existing technology are: the existing technology mainly relies on handheld devices for surveying and mapping of cultivated land. It is difficult to keep the equipment stable due to handheld operation, and it is difficult to meet the needs of high-precision data such as cultivated land boundaries and areas. In scenarios such as land transfer and large-scale agricultural project planning, subsequent decisions are easily affected by inaccurate data. Moreover, the battery life of handheld devices is limited. In long-term, large-area cultivated land surveying tasks, frequent charging seriously affects work efficiency. In addition, the operation of handheld devices is highly dependent on manual experience. The measurement techniques and proficiency of different operators vary greatly, resulting in a lack of consistency and reliability in the measurement results. Summary of the invention
