Introduction

Overview

The SL100 GNSS Land Leveling System is an important innovation in the field of GNSS high-precision positioning applied to precision agriculture. The system is composed of high precision GNSS positioning equipment, controllers, data communication equipment and high-brightness display equipment. It uses base station + mobile vehicle terminal or connects to network base stations for operation.

Features

1. The leveling system can be controlled manually and automatically, and the tablet displays the height of the reference plane and the real-time height information.
2. In the automatic mode, the site can be automatically leveled according to the set height, and two modes of slope and level site are supported.
3. The terrain information is displayed in different colors, which greatly improves work efficiency. It can help users understand the height and level of the entire site in real time, and make accurate judgments during operation, which largely improves work efficiency by more than 40%, and greatly saves time and cost. Compared with the traditional laser land leveling system and ordinary satellite leveling system, it has great working advantages.
4. The on-board terminal is compatible with our Autopilot system, intelligent spray system, driving assistance system, etc., which can greatly reduce the purchase cost of various equipment. For specific operation items, please refer to the following detailed description.

Benefits

1. Increase Yield
   Using GNSS Land Leveling System to accurately leveling the land can increase production by 20-30% compared with traditional leveling technology, which is 50% of the  unleveled land. These impressive results are obtained by applying the appropriate amount of water to the plants for their growth. The even distribution of water improves the environment for germination and plant growth and increases the yield of crops.

2. Save Irrigation Water
   After the field is leveled, the water used for irrigation can be fully utilized, so that the water can be evenly distributed throughout the field, so that the uneven flow of water will not cause the irrigation water cost to increase.

3. Save measurement cost
   There is no need to hire a survey team to measure the elevation of the land, with just a few minutes of training, anyone can accurately and quickly measure the elevation of the land after using GNSS Land Leveling System.

4. Reduce Fertilizer Loss
   After the field is precisely leveled, not only the water can be accurately used, but the fertilizer can also be stored in the roots of the plants, which can greatly reduce the loss of fertilizer during irrigation and drainage.

5. Control High Location Soil
   The high ground can be accurately leveled to obtain a uniform height, which reduces the erosion of the high soil by water and prevents the high soil from gathering in the low place.

Work Principle

The satellite provides the base station with positioning reference information, and the base station transmits the radio signal to the controller and through internal calculation, so that the controller can obtain more precise position information. The controller calculates the reference datum plane by real-time sampling, compares the position of the scraper body with the reference datum plane, and combines the corresponding algorithm to obtain the expansion and contraction amount of  the limit cylinder.

When the scraper body position is higher than the reference datum level, the limit cylinder automatically shortens, the scraper body descends, the scraper body remove the soil and drives the soil forward. when the scraper body is lower than the reference datum level, the limit cylinder automatically extends and the scraper body rises, and the soil in the scraper fills up to the lower ground. When leveling the ground, the limit cylinder is constantly expanding and contracting according to the terrain, and the scraper body continuously remove and fill the soil. After leveling for a period, the field can form a plane on the same terrain to achieve fine leveling

System Installation

This chapter introduces how to set up the system and make it start working properly.

Device Installation

GNSS Antenna Installation

The installation of GNSS antennas in the entire GNSS Land Leveling System is particularly important. Choosing a suitable installation location is the prerequisite for ensuring the leveling effect. Due to the difference in the model and appearance of the leveling machine, the installation location should also be determined according to the actual situation. Please note that the GNSS antenna must be placed directly above the center of the scraper, as shown in the figure below (Figure2.1).

When installing the GNSS antenna, please find the appropriate screws to fix the antenna mount

Figure 2.1 GNSS antenna installation

Cables Connection

Install according to the schematic diagram of the on-board mobile terminal (Figure2.3), and the solenoid valve control cables respectively control the lifting of the hydraulic cylinder of the leveler; during installation, in order to prevent the lifting from being contrary to the actual situation, an external lifting switch can be used for debugging. If it is contrary to the actual situation, the control line Change the positions of the two ports and then fix them.

3. The solenoid valve control cable and the antenna cable should be arranged separately, avoiding them entangled together

Display and Controller Installation
The tablet is the main equipment for the system to interact with the driver. It should be installed in the cab where is convenient for the driver to operate, such as the right or front of the cab seat. There is a tractor’s own wire hole inside the cab. Fix the mounting bracket, if it is not viable to drill holes in a suitable position for fixing, then fix the tablet on the bracket.
