Description

Technical Field

[0001] The invention relates to the technical field of greenhouse water and fertilizer, and in particular to a mobile greenhouse water, fertilizer and medicine intelligent pump station and a use method thereof. Background Art

[0002] Water and fertilizer management is a very important technical measure in greenhouse vegetable cultivation, and plays a very important role in increasing the yield and quality of greenhouse vegetables. Water-fertilizer integration technology is an important technology for water and fertilizer management in greenhouse vegetable cultivation. It integrates irrigation and fertilization, uses pipeline water and fertilization, and combines spraying to achieve water-fertilizer integration. Compared with traditional irrigation methods, it has the advantages of saving water, fertilizer, labor and time, and improving fertilizer efficiency.

[0003] There are many similar products with different focuses in China. According to their design structure and technical focus, these products can be roughly classified into the following categories:

[0004] 1. The solar greenhouse intelligent management integrated machine (patent number: CN202321740175.7) applied by Inner Mongolia Yanfeng Agricultural Biotechnology Co., Ltd. is a fixed water and fertilizer management equipment. The main technical innovation is the function of grinding and stirring granular fertilizers to improve the efficiency of granular fertilizers in greenhouse water and fertilizer management. A greenhouse water and fertilizer integrated intelligent irrigation system (patent number: CN202120917234.8) applied by the Northeast Institute of Geography and Agricultural Ecology of the Chinese Academy of Sciences is also a fixed water and fertilizer management equipment, focusing on online automatic control of irrigation and fertilization. The solar greenhouse water and fertilizer integrated irrigation control method and device based on the Internet of Things (patent number: 201811095803.4) applied by China Agricultural University is a fixed water and fertilizer management equipment, focusing on planting environment data collection, data processing and Internet of Things intelligent decision-making control, so as to improve the efficiency of water and fertilizer utilization.

[0005] 2. A greenhouse water-fertilizer-pesticide integrated structure applied by Guangdong Modern Agricultural Equipment Research Institute (patent number: 201820689824.8). This technology is a fixed water-fertilizer-pesticide management equipment. The main technical innovation is the integration of irrigation, fertilization and dosing (pesticide) devices, which greatly improves the utilization rate of water resources, fertilizers and pesticides, and reduces the cost of labor and equipment investment. A greenhouse water-fertilizer-gas integrated intelligent irrigation and waste liquid recovery system applied by Shandong Agricultural University (patent number: 201810072737.2). This technology is a fixed water-fertilizer management equipment. The main technical innovation is the integration of water, fertilizer, gas and waste liquid recovery devices. The water is magnetized pre-treated, and the gas is purified and disinfected with ultraviolet light. This technology has certain advancedness in the refined water-fertilizer management and green planting of greenhouses, which not only improves the coupling effect and utilization rate of water and fertilizer, but also reduces the viruses and bacteria in water and air. Nobelfeng (China) Agriculture Co., Ltd. applied for a greenhouse water, fertilizer and pesticide integrated system (patent number: 201720325385.8). This technology integrates functional devices such as irrigation, fertilization and spraying, saving labor and improving efficiency. Beijing Agricultural Information Technology Research Center applied for a greenhouse ozone precision control method and device based on multi-model fusion (patent number: 202110571199.3). This technology is a fixed greenhouse disinfection equipment, which mainly focuses on the precise control method of greenhouse ozone disinfection and sterilization, and provides precise control practice for greenhouse green control technology that uses ozone instead of pesticides. Beijing Agricultural Intelligent Equipment Technology Research Center applied for a greenhouse cluster ozone intelligent disinfection method and disinfection device using PID control (patent number: 201610694729.2). This technology is a fixed greenhouse disinfection equipment, and the main technical innovation is to achieve precision trimming and control of greenhouse ozone disinfection concentration with PID control function.

[0006] The water, fertilizer, medicine and other control equipment in these greenhouses all have certain innovations in their respective focus areas, and have actually solved some existing problems in the field of greenhouse cultivation, providing rich solutions for greenhouse cultivation, and providing intelligent control ideas for saving water, fertilizer, medicine and labor.

[0007] For the greenhouse planting industry, precise control of water, fertilizer, and pesticides is a rigid demand of industry users. Realizing environmental control data collection and intelligent decision-making is also the development trend of scientific planting. However, existing technical products generally have problems such as low functional integration, high cost, single application scenario, and technical barriers to use.

[0008] It is mainly reflected in the following shortcomings:

[0009] (1) Low functional integration: Greenhouse cultivation is an industry with a controllable environment and a high repetition rate. Although the industry has integrated one, two or more functional applications such as water, fertilizer, and medicine, there is no complete integration of pre-treatment, control, and application devices for water, fertilizer, and medicine. For example, for irrigation water, in addition to accurate irrigation water volume, it is also necessary to integrate different types of irrigation water sources and water quality treatment devices to meet the needs of different greenhouse cultivation users.

[0010] (2) The cost is too high. Apart from simple water, fertilizer and pesticide control systems, any equipment that integrates technology in the areas of water, fertilizer and pesticide pretreatment, precision control, environmental control, testing, and intelligent decision-making costs tens of thousands or even hundreds of thousands of yuan.

[0011] (3) Single application scenario: The equipment on the market is basically fixed, and each greenhouse needs to install one, which greatly increases the investment cost of greenhouse water, fertilizer and pesticide management. At the same time, for scenarios without power supply, water source (reservoir or water source without pressure) and farmers have one or two greenhouses, these devices are inadequate, especially in response to the development trend of future agricultural third-party services. The existing technical equipment has not considered the application scenario of mobile mobile operations and cannot meet future development needs.

[0012] (4) The technical threshold for use is high. For simple integrated water, fertilizer and pesticide management equipment, growers are required to have many years of rich management experience to use these devices well. For more complex intelligent equipment with more integrated functions and stronger self-control capabilities, growers are required to have more solid planting knowledge and equipment operation capabilities. Otherwise, the complex function use and professional parameter settings will increase the difficulty of planting for users and increase their planting costs. Summary of the invention

[0023] A method for using a mobile greenhouse water, fertilizer and medicine intelligent pumping station is applied to the above-mentioned mobile greenhouse water, fertilizer and medicine intelligent pumping station, comprising the following steps:

[0024] Step 1. Connect the mobile greenhouse intelligent water, fertilizer and medicine device to the vehicle through a towing rod, move the greenhouse intelligent water, fertilizer and medicine device to the outside of the greenhouse door where operation is required, and then connect the water inlet of the water, fertilizer and medicine device to the irrigation water source through a hose, and then connect the water outlet of the water, fertilizer and medicine device to the water inlet of the greenhouse irrigation or spraying device through the software. If there is power on site, the power supply in the water, fertilizer and medicine device can be switched to AC power mode, and the external power cord can be connected to the AC power on site. If there is no AC power supply on site, the power supply in the water, fertilizer and medicine device can be switched to generator mode.

[0025] Step 2. After the preparations are done, you can select irrigation mode, fertilization mode, and disinfection mode on the PLC control screen on the water, fertilizer and medicine device: when selecting irrigation mode, the user can choose between automatic irrigation mode and manual irrigation mode; when selecting fertilization mode, the user can choose between manual fertilization mode and automatic fertilization mode; when selecting disinfection mode, the user can choose between soil disinfection mode and air disinfection mode.

[0026] In the automatic irrigation mode, irrigation is automatically completed by the external mobile wireless environmental control sensor and the program in the PLC control screen, that is, the automatic program opens the fourth solenoid valve, the second solenoid valve and the self-priming pump in sequence. When the mobile wireless environmental control sensor detects that the soil data in the greenhouse reaches the program setting value, the system automatically closes the self-priming pump and closes the fourth solenoid valve and the second solenoid valve, and the mobile client notifies the customer that the automatic irrigation is completed;

[0027] In the manual irrigation mode, the user inputs irrigation parameters on the PLC control screen, such as irrigation water volume, irrigation duration, or upper limit of soil moisture content, and then the program turns on the fourth solenoid valve, the second solenoid valve and the self-priming pump in sequence. When the manual irrigation setting program is completed, the system automatically turns off the self-priming pump and closes the fourth solenoid valve and the second solenoid valve, and the mobile client notifies the customer that the automatic irrigation is completed.

[0028] In the automatic fertilization mode, the user only needs to add the target fertilizer into the fertilization bucket and then start the automatic fertilization program. The system will automatically analyze and decide on the fertilization plan through the data detected by the mobile wireless environmental control sensor and the EC sensor and PH sensor on the device, and according to the fertilization program automatically decided, the fourth solenoid valve, the second solenoid valve, the self-priming pump, the first fertilization solenoid valve, the second fertilization solenoid valve and the third fertilization solenoid valve on the fertilization bucket are opened in sequence, the first mixer, the second mixer and the third mixer on the fertilization bucket are opened, the first solenoid valve is opened, and the small solenoid valves No. 1, No. 2 and No. 3 on the fertilization channel are opened. After the fertilization program is completed, the system automatically closes the equipment and valves in sequence;

[0029] The manual fertilization mode requires the user to actively input fertilization parameters, such as fertilization time, fertilization amount, and fertilization ratio, through the PLC control screen. After the user sets the fertilization conditions, one or three granular water-soluble fertilizers or liquid fertilizers are added to the first fertilization barrel, the second fertilization barrel, and the third fertilization barrel, and then the self-priming pumps are turned on in sequence. When the water flow and pressure in the pipeline are stable, the first fertilization solenoid valve, the second fertilization solenoid valve, and the third fertilization solenoid valve on the fertilization barrel are opened in sequence according to the program. After the first liquid level gauge, the second liquid level gauge, and the third liquid level gauge on the fertilization barrel detect that the water level in the fertilization barrel reaches the set value, the first mixer, the second mixer, and the third mixer on the fertilization barrel start stirring, and then the first solenoid valve, the No. 1 solenoid valve, the No. 2 solenoid valve, and the No. 3 solenoid valve on the fertilization channel are opened, and then according to the fertilization ratios on the three fertilization channels, refer to the first float flow component, the second liquid level gauge, and the third liquid level gauge on the fertilization barrel. The numerical values ​​on the float flow component and the third float flow component adjust the opening and closing sizes of the first small gate valve, the second small gate valve and the third small gate valve on the fertilization channel to adjust the proportion of the three fertilization channels. When the liquid level in the fertilizer bucket is lower than the set value, the system will automatically open the first fertilizer solenoid valve, the second fertilizer solenoid valve and the third fertilizer solenoid valve on the fertilizer bucket to automatically add clean water to the fertilizer bucket. When the EC sensor and PH sensor on the pipeline detect that the pipeline value is lower than the warning value, the system automatically shuts down the first mixer, the second mixer and the third mixer. At the same time, the mobile client notifies the user that if the user fails to intervene in the operation within the system set time, the system will automatically close the solenoid valves No. 1, No. 2 and No. 3 on the fertilization channel, and at the same time, close the fourth solenoid valve, the second solenoid valve and the self-priming pump in turn, or the system also shuts down the equipment in turn after completing the set fertilization program.

[0030] In the soil disinfection mode, the system opens the fifth solenoid valve, the second solenoid valve, the fourth solenoid valve, the third solenoid valve, and the self-priming pump in sequence. After the water pressure stabilizes, the oxygen generator and the ozone generator are turned on in sequence, and the high concentration of ozone and the irrigation time are set on the PLC control panel. After the continuous execution is completed, the system automatically turns off the ozone generator, the oxygen generator, the fourth solenoid valve, the self-priming pump, the fifth solenoid valve, and the second solenoid valve in sequence, and notifies the user through the mobile client; in the air disinfection mode, all start and stop sequences are the same, except that the ozone concentration is set to a lower level. The irrigation time is determined by the mobile ozone concentration sensor in the greenhouse, and the shutdown procedure is started when the set concentration is reached.

[0031] (III) Beneficial effects

[0033] (1) Innovation in application scenarios: Currently, all existing greenhouse water, fertilizer and pesticide equipment are fixed, either one set of equipment for one greenhouse or one set of equipment for one park. However, in terms of the overall equipment investment cost, the cost of fixed greenhouse water, fertilizer and pesticide equipment is much higher than the mobile intelligent water, fertilizer and pesticide equipment of the present invention. In terms of equipment utilization, the invention has the function of mobile operation, which greatly improves the utilization rate of equipment. In terms of greenhouse type, the invention integrates dual power supply switching function and self-priming pump, which is suitable for water, fertilizer and pesticide management in all different types of greenhouses. One or several greenhouse parks only need to purchase one or several devices to complete the precise water, fertilizer and pesticide management function. It can even purchase services from a third-party professional water, fertilizer and pesticide service company that uses the equipment, thereby minimizing the investment cost of greenhouse planting facilities and equipment and human resources.

[0034] (2) Innovation in applicable groups: Currently, existing greenhouse water, fertilizer and pesticide equipment is only suitable for greenhouse growers. The equipment of this invention can be used by both greenhouse growers and third-party service agencies.

[0035] (3) Innovation to improve functions: Currently, the existing greenhouse water, fertilizer and pesticide equipment only integrates application functions in terms of water saving, fertilizer saving, pesticide saving and labor saving, while the invention integrates traction mobile platform function, dual power switching function, negative pressure self-priming water lifting function, main water supply function, super membrane water filtration function, irrigation water activation function, three-way mixing and proportional fertilization function, two-way soil and air ozone disinfection function, mobile wireless environmental control data detection function, PLC automatic control function, Internet of Things and cloud platform function. It not only integrates basic functions in terms of water saving, fertilizer saving, pesticide saving and labor saving, but also improves the functional integration in terms of improving equipment utilization, reducing investment in greenhouse ancillary equipment, irrigation water treatment, water-fertilizer coupling, pesticide substitution, automatic control Internet of Things and environmental control monitoring, so that users can grow crops without worries with just one machine in hand.

[0036] (4) Innovation of future trends: Green planting, precise environmental control, intelligent control, and professional services are the future development trends of agriculture. This invention is guided by industry policies, takes development trends as its goal, is based on planting users, and aims at green products to improve the mobile intelligent water, fertilizer and medicine device.

[0055] A method for using a mobile greenhouse water, fertilizer and medicine intelligent pumping station is applied to the above-mentioned mobile greenhouse water, fertilizer and medicine intelligent pumping station, comprising the following steps:

[0056] Step 1. Connect the mobile greenhouse intelligent water, fertilizer and medicine device to the vehicle via the traction rod 4, move the greenhouse intelligent water, fertilizer and medicine device to the outside of the greenhouse door where operation is required, and then connect the water inlet of the water, fertilizer and medicine device to the water reservoir through a hose. When the irrigation water source is a reservoir, put the bottom valve of the water inlet pipe into the reservoir and connect it. Then connect the water outlet of the water, fertilizer and medicine device to the water inlet of the greenhouse irrigation or spraying device through the software. If there is power on site, the power supply in the water, fertilizer and medicine device can be switched to the AC power mode, and the external power cord can be connected to the AC power on site. If there is no AC power supply on site, the power supply in the water, fertilizer and medicine device can be switched to the generator mode.

[0057] Step 2. After the preparations are done, you can select irrigation mode, fertilization mode, and disinfection mode on the PLC control screen on the water, fertilizer and medicine device: when selecting irrigation mode, the user can choose between automatic irrigation mode and manual irrigation mode; when selecting fertilization mode, the user can choose between manual fertilization mode and automatic fertilization mode; when selecting disinfection mode, the user can choose between soil disinfection mode and air disinfection mode.

[0058] In the automatic irrigation mode, irrigation is automatically completed by the external mobile wireless environmental control sensor and the program in the PLC control screen. The automatic program opens the fourth solenoid valve 1123, the second solenoid valve 1118 and the self-priming pump 05 in sequence. When the mobile wireless environmental control sensor detects that the soil data in the greenhouse reaches the program setting value, the system automatically closes the self-priming pump 05 and closes the fourth solenoid valve 1123 and the second solenoid valve 1118, and the mobile client notifies the customer that the automatic irrigation is completed;

[0059] In manual irrigation mode, the user inputs irrigation parameters on the PLC control screen, such as irrigation water volume, irrigation duration, or upper limit of soil moisture content, and then the program turns on the fourth solenoid valve 1123, the second solenoid valve 1118 and the self-priming pump 05 in sequence. When the manual irrigation setting program is completed, the system automatically turns off the self-priming pump 05 and the fourth solenoid valve 1123 and the second solenoid valve 1118, and the mobile client notifies the customer that the automatic irrigation is completed.

[0060] In the automatic fertilization mode, the user only needs to add the target fertilizer into the fertilization bucket and then start the automatic fertilization program.
