Embodiment 1

[0036] Such as figure 1 and figure 2 As shown, a saline-alkali soil fertilizer spraying system includes:

[0037] The central control room 1, the central control room 1 includes the central satellite antenna for wireless communication with the Beidou satellite, the central Beidou satellite communication module electrically connected with the central satellite antenna, the central control module electrically connected with the central Beidou satellite communication module, and the central control module Electrically connected human-computer interaction interface and image processing module;

[0038] The fertilizer spraying device, the fertilizer spraying device comprises a vehicle and a fertilizer storage tank 7 arranged on the vehicle, the fertilizer storage tank 7 is provided with a plurality of spray pipes 5, the outer end of the spray pipe 5 is provided with a nozzle 4, and the inner portion of the spray pipe 5 The end is connected with the outlet port of the pump; in th...

Embodiment 2

[0046] Such as figure 1 and figure 2 Shown, a kind of saline-alkali land uses the control method of fertilizer spraying system, comprises the following steps:

[0047] Step S1: The central Beidou satellite wireless communication module uses the central satellite antenna to communicate with the Beidou satellite to obtain images of areas to be sprayed;

[0048] Step S2: The central control module transmits the image of the sprayed area to the image processing module, and the image processing module obtains the distance data of the area to be sprayed by analyzing the image of the sprayed area, and transmits the distance data to the central control module; image processing The module can use the coordinate method to obtain the length and area of ​​the image.

[0049] Step S3: The central control module calculates the one-way fertilizer spraying amount according to the received distance data and the preset vehicle speed; the central control module then transmits the wireless dat...

Abstract

The invention discloses a fertilizer spraying system for saline-alkali land and a control method thereof, wherein the system includes a central control room, a fertilizer spraying device and a vehicle-mounted control terminal arranged on the fertilizer spraying device, and the central control room and the vehicle-mounted control terminal are respectively equipped with satellite antennas And the Beidou satellite communication module, so that the central control room and the vehicle control terminal can use the Beidou satellite to communicate. When the present invention is used for spraying fertilizer on saline-alkali land, the central control room uses the Beidou satellite to obtain the image to be operated before the operation, and after analyzing the image, the area of ​​the area to be operated, the one-way distance and other data are obtained, and the above data is used to calculate the total distance. The amount of fertilizer required, the speed of the fertilizer spraying device, etc. are pre-calculated. During the operation process, the on-board control terminal obtains the actual operation data through the speed sensor and the liquid level sensor, so as to adjust in real time, and finally spray fertilizer evenly and carry an appropriate amount of fertilizer. It can be seen that the present invention utilizes the Beidou satellite to realize the purpose of uniform fertilization.

Description

technical field [0001] The invention relates to the technical field of orchard management on saline-alkali land, in particular to a fertilizer spraying system for saline-alkali land and a control method thereof. Background technique [0002] With the control of saline-alkali land, crops have been planted on a large area of ​​saline-alkali land. In each stage of the growth of crops, operations such as spraying water and spraying fertilizer on the crops are required. Usually, saline-alkali land is mostly located in areas far away from cities such as the coast. When spraying fertilizer, a fertilizer spraying device is required to transport the fertilizer with a good ratio to the saline-alkali land. Because the area of ​​saline-alkali land to be operated and the fertilizer requirements of crops cannot be accurately grasped, it is easy to have insufficient fertilizer transportation, or carry too much fertilizer to cause waste; it will also lead to uneven fertilizer spraying. C...
