Embodiment 1

[0035] figure 1 The flow chart of the land leveling method provided by Embodiment 1 of the present invention, such as figure 1 As shown, the land leveling method includes:

[0036] Step 1. Obtain the location information of the location to be leveled in real time through the receiving mechanism based on the satellite positioning system, wherein the location information includes at least an elevation value.

[0037] Step 2. Comparing the elevation value with the preset reference elevation to generate a leveling control signal.

[0038] Step 3. Control the land leveling operation of the leveling mechanism according to the leveling control signal, so as to level the land to a preset reference elevation.

[0039] The receiving mechanism based on the satellite positioning system mainly includes a receiving antenna and a processing terminal, through which the satellite signal is received by the receiving antenna and transmitted to the processing terminal, and the processing termin...

Embodiment 2

[0052] figure 2 It is a flow chart of the land leveling method provided by Embodiment 2 of the present invention. On the basis of Embodiment 1 above, the receiving mechanism includes at least a receiving antenna, such as figure 2 Shown, this land leveling method also comprises after above-mentioned step 1:

[0053] Step 11, obtaining the attitude information of the receiving antenna in real time;

[0054] Step 12. Correct the elevation according to the attitude information, and then perform step 2.

[0055] Usually the receiving mechanism includes a receiving antenna for receiving satellite signals, which is usually placed on the leveling mechanism and carried by the leveling mechanism. However, due to the complex terrain of the land to be leveled, the leveling mechanism will vibrate during travel, which will also cause The shaking of the receiving antenna makes the elevation value obtained through the position calculation of the receiving antenna have a large error, which...

Embodiment 3

[0068] The embodiment of the present invention also provides a land leveling control device, which can implement the land leveling method provided by the embodiment of the present invention, image 3 It is a schematic structural diagram of the land leveling control device provided by Embodiment 3 of the present invention, as image 3 As shown, the land leveling control device includes a receiving mechanism 201 and a comparison module 202 .

[0069] The receiving mechanism 201 is used for acquiring the location information of the location to be leveled in real time based on the satellite positioning system, wherein the location information includes at least an elevation value.

[0070] The comparison module 202 is used to compare the elevation value with the preset reference elevation to generate a leveling control signal to the leveling mechanism to control the land leveling operation of the leveling mechanism so as to level the land to the preset reference elevation.

Abstract

The invention discloses a land leveling method, a land leveling control device and a land leveling device. The land leveling method comprises: obtaining the position information of the position to be leveled in real time through a receiving mechanism based on a satellite positioning system, wherein the position information includes at least an elevation value ;Comparing the elevation value with the preset reference elevation to generate a leveling control signal; controlling the land leveling operation of the leveling mechanism according to the leveling control signal, so as to level the land to the preset reference elevation. The land leveling method is based on the satellite positioning system to obtain the elevation value of the position to be leveled in real time and compare it with the preset reference elevation to generate a leveling control signal to control the leveling operation of the leveling mechanism. The operation range is not limited, and any area of ​​the leveling ground can be used. blocks for land leveling.

Description

technical field [0001] The invention relates to mechanical control technology, in particular to a land leveling method, a land leveling control device and a land leveling device. Background technique [0002] At present, in terms of land leveling operations, the methods of land leveling mainly include conventional leveling, laser control leveling and other methods. [0003] The leveling equipment used in the conventional leveling method generally includes bulldozers, scrapers and scrapers, etc. This kind of conventional land leveling equipment has the characteristics of large amount of earth moving and relatively low leveling costs, and is suitable for large undulating ground, The rough leveling of farmland with poor original leveling degree can effectively change the macro-topography of farmland. [0004] The effect of this conventional land leveling mainly depends on the construction accuracy of bulldozers and scrapers. However, since the lifting of the bulldozer is manu...
