[0002] The imbalance in the allocation of water and soil resources, soil salinization and shortage of fresh water resources are important factors restricting the development of agriculture in arid and semi-arid areas. The development and utilization of underground saline water for irrigation in saline water areas is an effective way to alleviate the contradiction between the supply and demand of fresh water resources in the area and solve the problem of soil salinization. The use of mixed irrigation of salty and fresh water can reduce the salt content of irrigation water or change its salt composition, reducing the harm of salt to crops and soil.

[0003] As an advanced irrigation method, sprinkler irrigation with salty and fresh mixed water is increasingly widely used. However, when sprinkler irrigation is carried out with salty and fresh mixed water, crops are not only subjected to soil salt stress, but also damaged by leaf absorption of salt, thus affecting crop yield. Under the condition of sprinkler irrigation with salty and fresh mixed water, the crop canopy will intercept part of the irrigation water. The water retained in the crop canopy contains salt, which will damage the crop due to leaf absorption.

[0004] In order to solve the above technical problems, an intelligent salt-fresh water mixed field sprinkler irrigation system is proposed. Summary of the invention

The salt water control module 22 includes a salt water pump and a salt water inlet device. The water storage module 24 includes a water storage pressure tank. The fresh water pump and the salt water pump are connected to the water storage pressure tank through the fresh water inlet device and the salt water inlet device respectively. The pressure sensor of the pressure monitoring module 23 is installed in the fresh water inlet device, the salt water inlet device and the water storage pressure tank to monitor the water pressure. The pressure monitoring module 23 also includes a pressure alarm module 25 to issue an alarm and perform emergency processing when abnormal pressure is detected.

[0027] The sprinkler unit 30 includes a flow monitoring module 31, a duration control module 32 and a frequency control module 33. The flow monitoring module 31 is used to monitor the water consumption of sprinkler irrigation, the duration control module 32 is used to monitor the sprinkler irrigation duration, and the frequency control module 33 is used to adjust the sprinkler irrigation interval. The sprinkler unit 30 includes a sprinkler irrigation device, and the sprinkler irrigation device has a built-in water quality mineralization regulator. In conjunction with the flow monitoring module 31, the duration control module 32 and the frequency control module 33, the mineralization of salty and fresh mixed water, the fresh water sprinkler irrigation duration and water volume, and the water volume of the mixed water sprinkler irrigation duration can be input.

[0028] The monitoring unit 40 includes an image monitoring module 41, a data recording module 42 and an abnormal alarm module 43. The image monitoring module 41 includes a field image acquisition device and a mobile inspection image acquisition device. The mobile inspection image acquisition device uses a drone to complete inspections at regular intervals. When installing the field image acquisition device, the installation quantity and installation location in a certain area should be pre-allocated. The field image acquisition device and the mobile inspection image acquisition device record the sprinkler irrigation effect. The data recording module 42 records the sprinkler irrigation effect obtained by the image monitoring module 41 and the corresponding sprinkler irrigation mode adopted. The abnormal alarm module 43 issues an alarm prompt when the sprinkler irrigation effect does not meet the standard and the field status is abnormal.

[0029] In one embodiment, growth information of field crops is obtained through regular drone inspections, and real-time monitoring of field crops is performed using image acquisition equipment. AI is used to intelligently identify whether the residual salt content on the leaves exceeds the standard, so that fresh water sprinkler irrigation is automatically completed when the salt content exceeds the standard to wash away the residual salt on the leaves.

[0030] In one embodiment, a sprinkler irrigation system is composed of an equipment control system, a fresh water pump, a salt water pump, a water storage pressure tank and a sprinkler irrigation device. Both the fresh water pump and the salt water pump are frequency conversion controlled pumps, which are controlled by the equipment control system. The fresh water pump and the salt water pump are connected to the water storage pressure tank for water supply. Fresh water and salt water are mixed in the water storage pressure tank, and fresh water and salt water are stored. A pressure sensor is installed in the tank to monitor the water pressure. The sprinkler irrigation device is connected to the water storage pressure tank through a sprinkler irrigation water outlet device to irrigate farmland crops. The sprinkler irrigation water outlet device has a built-in flow meter and a water quality mineralization regulator, which are controlled by the equipment control system together with the sprinkler irrigation device to achieve integrated mixed sprinkler irrigation.

[0031] When the present invention is working, variable parameters are pre-input or irrigation methods are selected according to the salt tolerance of leaves of different crops and the state of planting soil, such as the mineralization of salty and fresh mixed water, the duration and water volume of fresh water sprinkler irrigation, and the water volume of mixed water sprinkler irrigation. If the irrigation method of fresh water washing-salty irrigation-fresh water shower is selected, fresh water is first sprinkled to rinse the residual salt on the leaves, and fresh water is supplied to the water storage module 24 through the fresh water control module 21, and sprinkler irrigation is carried out in conjunction with the sprinkler irrigation device of the sprinkler unit 30, and then the salty and fresh mixed water is switched to sprinkler irrigation to complete the normal salty and fresh water mixed sprinkler irrigation, and the fresh water control module 21 and the salt water control module 30 are coordinated in a specified ratio. Module 22 supplies fresh water and salt water, which are mixed in the water storage module 24 and then sprinkled. Finally, fresh water is used for sprinkler irrigation to wash away the residual salt on the leaves. The duration and water volume can be customized through the duration control module 32 and the flow monitoring module 31 in cooperation with the central control unit 10. During the sprinkler irrigation process, the image monitoring module 41 obtains crop image information in real time to prevent excessive residual salt on some crop leaves from affecting growth. When the crops are abnormal, the abnormal alarm module 43 issues a warning. The central control unit 10 has a preset emergency treatment plan, and sprinkler irrigation is implemented through the emergency treatment plan when manual processing is unable to be timely.

[0032] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
