Description

Intelligent irrigation control system and control method thereof

Technical field

The invention belongs to the field of smart agriculture, and particularly relates to a smart irrigation control system and a control method thereof.

Background technique

Agriculture is generally divided into two models for research: facility agriculture and field farming agriculture. Correspondingly, smart agriculture also proposes different automatic and smart irrigation methods and devices based on the two models of smart facility agriculture and smart field farmland agriculture. There are many automated management methods and devices for smart facility agriculture, but based on the hardware construction of the national high-efficiency water-saving irrigation pipe network system, it is suitable for the automated and intelligent management methods of field farmland agriculture for growing food and cash crops. And the device is almost blank.

The reality is that water-saving irrigation implements a rotation irrigation system. The farmers’ rotation time requirements under the rotation irrigation system are very specific and strict. The farmers must go to the underground wells and the semi-stop valve wells to manually open the underground during their own rotation irrigation time. The well valve and the semi-stop valve are switched on and off, and multiple valves on the ground must be opened manually. In actual field irrigation, the field land is not completely level, but has different slopes and heights. Terraces, mountain slopes, forest areas, scenic green areas, and desert green areas all belong to this type of terrain. For field irrigation, in order to avoid pipe bursts caused by excessive water pressure, after watering one field, first open the valve to water the other field, and then close the valve on the other side. Due to the relatively large area of farmland in the north and the different slopes, different water pressures will be generated. To avoid water hammer, pipe bursting, pipe dropping, etc., farmers can only use their feet to continuously press the surface hoses. Manually adjust the valve opening and closing degree. This manual valve opening method is time-consuming, labor-intensive, water-consuming and inefficient in irrigation management. In the actual irrigation management work, it takes about 40 minutes to manually adjust the 20 valves of a water outlet pile belt. After one side is irrigated according to the irrigation schedule, the other side needs to be irrigated, which takes another 40 minutes. This adjustment process In the process, water will be wasted due to time-consuming.

The solenoid valve used in the existing agricultural automatic irrigation system can only perform two operations of "full open" and "full close", and is not suitable for irrigation of agricultural fields. On the other hand, the existing automated irrigation system for facility agriculture requires underground wires or poles to supply power to it, which is very inconvenient and impractical in the field of cultivated land.

Summary of the invention

The first objective of the present invention is to provide a smart irrigation control system, through which automatic control of water, fertilizer and medicine integrated irrigation is realized, without the need to manually open valves on site, saving time and effort, saving water, and avoiding water hammer in underground well valves In the occurrence of production accidents such as pipe bursts in the pipe network, irrigation management has been improved and the efficiency of irrigation management has been significantly improved.

The terminal execution module of the irrigation equipment controls the corresponding intelligent control irrigation actuator to execute corresponding actions according to the received irrigation instruction to irrigate, fertilize, and apply the field;

The feedback data module feeds back the execution data of the irrigation equipment to the data collection module.

The feedback data module also sends the working status data of the irrigation equipment to the data acquisition module, the data acquisition module sends the working status data to the data receiving module, and the data receiving module forwards the data to the central processing module. The central processing module determines whether the irrigation equipment is normal. The feedback data module sends the working status data of the irrigation equipment to the data acquisition module every set time (for example, feedback once every 15 minutes), so that it can quickly determine whether the irrigation equipment is working and eliminate the trouble when it takes time; the working status data includes voltage , Pressure, flow, heart rate, etc.

The irrigation equipment data includes the number, model, name, location, etc. of each irrigation equipment; the crop data includes pictures of crop growth (whether there are insects, whether they are dry, the height of the crop, etc.); the soil data includes soil surface temperature and humidity, Soil underground temperature and humidity, soil compaction, soil nutrients such as nitrogen, phosphorus, potassium, pH value, and insect eggs; the surrounding environment data includes air temperature and humidity, sunlight exposure, etc.; the operation land data includes operations Data such as the number of acres of land, the slope of the surface, the grouping of the operating land, and the crop yield. The valve data, crop data, soil data, surrounding environment data, and operating land data can be automatically collected by the corresponding sensors, or can be manually entered in the background after the detection by the corresponding detection instrument, so the data collection module can also be called It is a module for collecting data from irrigation equipment/manual background input data. For example, soil surface temperature and humidity, soil underground temperature and humidity, etc. can be collected by temperature and humidity sensors, air temperature and humidity can be collected by temperature and humidity sensors, and surrounding weather data can also be manually entered. As long as it can achieve various data collection.

The irrigation equipment includes various valves, large head filters, water storage sedimentation tanks and various pipelines. The valves include main valves, fertilizer control valves, drug control valves, underground well valves, semi-stop valves and surface valves. The water storage sedimentation tank is connected to the main valve through a pipeline, the main valve is connected to the large-head filter through the pipeline, and the large-head filter is connected to multiple underground well valves through the pipeline. The underground well valves are connected in series with zero or more stop valves through the pipeline. Multiple surface valves, fertilizer control valve and drug control valve are connected to the pipeline connecting the large-head filter and the underground well valve, or connected to the pipeline between the large-head filter and the water storage sedimentation tank.

The feedback data module sends the working status of the large header filter to the data acquisition module, the data acquisition module forwards it to the data receiving module, and the data receiving module forwards it to the central processing module. The central processing module judges according to the working status of the large header filter Whether the big head filter needs to be cleaned, if it needs cleaning, send an automatic cleaning command to the irrigation equipment management module, the irrigation equipment management module forwards the automatic cleaning command to the irrigation equipment terminal execution module, and the irrigation equipment terminal execution module controls the automatic cleaning of the big head filter .

The working state of the large-head filter includes normal, blocked, closed, and open states.

The central processing module classifies, analyzes, judges and processes the data to form irrigation requirements specifically as follows:

The central processing module first classifies the received data, and classifies it according to irrigation equipment data, crop data, soil data, surrounding environment data, and operating land data; then combines the classified data with the stored setting data for analysis, judgment, and After the treatment, the irrigation requirements are formed. The irrigation requirements include whether irrigation, fertilization, and pesticide application are required, where irrigation, fertilization, and pesticide application are needed, and what is the amount of irrigation, fertilization, and pesticide application. For example: A. When the humidity in the soil air is lower or higher than the set value, the central processing module alarms and automatically sends the irrigation requirements to the irrigation equipment management module, whether to switch the terminal execution module of the irrigation equipment; B. Local surface temperature and humidity When the value is higher than the setting, the central processing module alarms and automatically sends the irrigation requirements to the irrigation equipment management module, whether to switch the terminal execution module of the irrigation equipment; C. When the N, P, K and other related fertilizer element data are lower or higher than the setting When the value is set, the central processing module alarms and automatically sends the irrigation requirements to the irrigation equipment management module, whether to switch the irrigation equipment terminal execution module.

The feedback data module also sends the operating voltage value of the irrigation equipment to the data receiving module, which forwards the data receiving module to the central processing module, and the central processing module determines whether the operating voltage is normal. To prevent the occurrence of irrigation accidents.

The above-mentioned smart irrigation control system is a software system of the IoT irrigation system, and is used to control the smart irrigation actuator of the hardware system of the IoT irrigation system.

The second objective of the present invention is to realize precise control of the opening and closing degree of each valve, and to realize automatic adjustment of the opening and closing degree of the valve from 0 to 360°.

In order to achieve this purpose, the data collection module also needs to collect the water pressure in the pipeline. Therefore, it is necessary to install a water pressure detection device on the water inlet or outlet pipe of each valve to detect the water pressure in the pipeline, and to detect the water pressure in the pipeline. The water pressure is sent to the data acquisition module, and the data acquisition module is sent to the central processing module. The central processing module compares the received water pressure with the rated water pressure of the pipeline to determine whether the rated water pressure is reached, and if not, then Send a continuous adjustment command to the irrigation equipment management module. If it is reached, then send a stop adjustment command to the irrigation equipment management module. The irrigation equipment management module will issue the corresponding command to the irrigation equipment terminal execution module, and the irrigation equipment terminal execution module will act according to the received Order to continue to issue action instructions to the intelligent control irrigation actuator to adjust the valve opening and closing degree or stop adjusting the opening and closing degree of each valve. Under the premise of not bursting the pipe, try to adjust the opening and closing degree of the valve as much as possible, so that the water pressure in the irrigation pipe network is consistent, and the irrigation is even, and the irrigation efficiency is improved.

Since the 0-360° working stroke of the intelligent control irrigation actuator (installed on each valve) can be realized, the surface valve opening and closing degree can be controlled by 0-360°. The intelligent control irrigation actuator can be connected with two-way, three-way, Multi-way valves such as four-way and five-way valves can realize water output control in all outlet directions. Since water can be controlled in multiple directions, the number of surface valves and the number of intelligently controlled irrigation actuators can be reduced, which can greatly save costs.

The third object of the present invention is to provide a smart irrigation control method. The specific steps of the method are:

Step 1. The data collection module sends the collected irrigation equipment data, crop data, soil data, surrounding environment data and operating land data to the data receiving module;

Step 2: The data receiving module sends the received irrigation equipment data, crop data, soil data, surrounding environment data, and operating land data to the central processing module;

Step 3: The central processing module classifies, analyzes, judges, and processes the received data to form irrigation requirements, and sends the irrigation requirements to the irrigation equipment management module;

Step 4: The irrigation equipment management module forms an irrigation instruction according to the received irrigation request or dormancy request, and issues the irrigation instruction to the irrigation equipment terminal execution module;

Step 5: The terminal execution module of the irrigation equipment controls the corresponding intelligent control irrigation actuator according to the received irrigation instruction, and executes the corresponding actions to perform irrigation, pesticide application, and fertilization.

Step 6. The feedback data module feeds back the execution data of the irrigation equipment to the data acquisition module, which sends the data acquisition module to the data receiving module, and the data receiving module to the central processing module. The central processing module compares and judges based on the execution data and issues the corresponding shutdown The instruction is sent to the irrigation equipment management module, and the irrigation equipment management module sends it to the irrigation equipment terminal execution module to control the corresponding intelligent control irrigation actuator to end the corresponding action and stop irrigation, pesticide application, and fertilization.

Step 5 is specifically: there is an irrigation command in the irrigation command to control the main valve to open, and also to control the corresponding underground valve and surface valve to open. The underground valve and surface valve that do not need to be opened are in a dormant state and closed; especially wake up After the underground well valve and when the irrigation system is executed, the underground well valve shall be opened and closed step by step in multiple positions until the underground well valve is fully opened. When the underground well valve is closed, the opening and closing degree of the underground well valve must also be closed step by step. Until the underground well valve is completely closed, the step-by-step adjustment setting work of increasing and decreasing is essentially to delay the opening and closing of the underground well valve. Doing so will certainly avoid accidents such as water hammer and pipe burst in underground pipe network facilities. If there is a fertilization instruction in the irrigation instruction, open the fertilizer control valve, otherwise the control fertilizer control valve is dormant and in a closed state; if there is a fertilizer instruction in the irrigation instruction, the drug control valve is opened, otherwise the control drug control valve is dormant and in a closed state.

In step 5, after each valve is opened, the water pressure detection device detects the water pressure in the pipeline and sends the detected water pressure to the data acquisition module, the data acquisition module sends the data acquisition module to the data reception module, and the data reception module forwards it to the central processing module , The central processing module compares and judges with the rated water pressure, and sends a command to continue or stop adjustment to the irrigation equipment management module according to the judgment result. The irrigation equipment management module forwards it to the irrigation equipment terminal execution module, and the irrigation equipment terminal execution module receives The command continues to control the intelligent control irrigation actuator to adjust the valve opening and closing degree or stop adjusting the valve opening and closing degree.
