Description

Farmland irrigation methods and farmland irrigation systems

The present invention relates to a farmland management technology, and in particular to a farmland irrigation method and a farmland irrigation system.

At present, water level tracking in farmland mostly relies on manual labor. For example, when water masters conduct manual inspections and find that the water level in farmland is insufficient, they can manually open the water gates. When the water level has met the irrigation demand, watermen use sandbags to fill and block the waterway to manually adjust the water level. It can be seen from this that current water level tracking consumes a lot of manpower, occasionally involves accidents or dangers, and is not immediate.

In view of this, embodiments of the present invention provide a farmland irrigation method and a farmland irrigation system, which can provide smart irrigation functions to meet the needs of farmland water supply.

The farmland irrigation system in the embodiment of the present invention includes (but is not limited to) a water level monitoring unit, a control unit and a gate monitoring unit. The water level monitoring unit is used to measure the water level height of farmland. The control unit is coupled to the water level monitoring unit and used to provide a crop growth stage evaluation module and a water demand evaluation module. The crop growth stage assessment module determines the growth stage of crops in farmland. The water demand assessment module determines the water demand corresponding to the growth stage. The control unit compares the water demand and water level height to generate a comparison result, and generates a gate control instruction based on the comparison result. The gate monitoring unit is coupled to the control unit and used to control the operation of the gate according to the gate control instructions to release water to the farmland or supply water to the farmland.

The farmland irrigation method of the embodiment of the present invention includes (but is not limited to) the following steps: measuring the water level of the farmland, determining the growth stage of the crops in the farmland, determining the water demand corresponding to the growth stage, and comparing the water demand and the water level height to generate a comparison. As a result, a gate control instruction is generated according to the comparison result, and the operation of the gate is controlled according to the gate control instruction to release water to the farmland or supply water to the farmland.

Based on the above, according to the farmland irrigation method and farmland irrigation system of the embodiment of the present invention, the growth stage of the crops is estimated, the current amount of water required by the farmland is calculated, and the opening and closing of the water gate is controlled accordingly. In this way, farmland can be irrigated automatically and irrigation manpower and water can be saved.

In order to make the above-mentioned features and advantages of the present invention more obvious and easy to understand, embodiments are given below and described in detail with reference to the accompanying drawings.

Figure 1 is a block diagram of a farmland irrigation system 1 according to an embodiment of the present invention. Please refer to Figure 1. The farmland irrigation system 1 includes (but is not limited to) a control unit 10, a water gate monitoring unit 12, a water level monitoring unit 13, a network transmission unit 14, a data storage unit 15, an input interface 16 and a micro weather station monitoring unit. 17. The farmland irrigation system 1 is suitable for various types of farmland 11. It should be noted that the embodiment of the present invention does not limit the type, quantity and/or scale of crops grown in the farmland 11 .

The control unit 10 may be a central processing unit (CPU), a graphics processing unit (GPU), or other programmable general-purpose or special-purpose microprocessor (Microprocessor), programmable Controller, Field Programmable Gate Array (FPGA), Application-Specific Integrated Circuit (ASIC), neural network accelerator or other similar components or a combination of the above components.

In one embodiment, the control unit 10 is used to provide a crop growth stage assessment module 18 and a water demand assessment module 19 . The crop growth stage assessment module 18 and the water demand assessment module 19 are software modules, and are loaded into the software modules via the control unit 10 to execute corresponding functions.

The water gate monitoring unit 12 is coupled to the control unit 10 . In one embodiment, the water gate monitoring unit 12 is used to control the operation of one or more gates. These gates are used to control access to waterways on farmland 11. For example, if the water supply gate is opened, the water flows into the farmland 11; if the water supply gate is closed, the water stops flowing into the farmland 11. If the water outlet gate is opened, the water flows out from the farmland 11; if the water outlet gate is closed, the water stops flowing out from the farmland 11.

The water level monitoring unit 13 is coupled to the control unit 10 . In one embodiment, the water level monitoring unit 13 is used to measure the water level height of the farmland 11 . For example, identifying water level height through images.

It should be noted that different farmlands 11 may be equipped with corresponding water gate monitoring units 12 and water level monitoring units 13 respectively.

The network transmission unit 14 is coupled to the control unit 10 , the water gate monitoring unit 12 , the water level monitoring unit 13 and the data storage unit 15 . The network transmission unit 14 may be a communication transceiver supporting Wi-Fi, 4G mobile network or other communication technologies. In one embodiment, the network transmission unit 14 is used to transmit data, instructions or information from connected units.

The data storage unit 15 is coupled to the input interface 16 and the micro weather station monitoring unit 17 . The data storage unit 15 can be any type of fixed or removable random access memory (Radom Access Memory, RAM), read only memory (Read Only Memory, ROM), flash memory (flash memory), traditional hardware. Hard Disk Drive (HDD), Solid-State Drive (SSD), nonvolatile memory or similar components. In one embodiment, the data storage unit 15 is used to store program codes, software modules, configurations, data (for example, water level height, growth stage, water demand, comparison results, weather information, etc.) or files, and the contents thereof Will be detailed later.

The input interface 16 is a user interface and can be presented through various types of displays. In one embodiment, the input interface 16 is used for the user to input information (for example, the type of crops of the farmland 11, the date of planting and/ or corresponding sluice gate).

The micro weather station monitoring unit 17 includes (but is not limited to) temperature, humidity, illumination, air pressure or other types of sensors. The sensing results (such as temperature, humidity and illumination) obtained by these sensors can be used as local meteorological information. The micro weather station monitoring unit 17 can be installed on the farmland 11 or around it.

In the following, the method described in the embodiment of the present invention will be explained with reference to various components, modules and devices in the farmland irrigation system 1 . Each process of this method can be adjusted according to the implementation situation, and is not limited to this.

The existing automatic irrigation and monitoring systems can only provide simple functions such as water level monitoring and water gate control, but cannot automatically irrigate according to the growth stage of each farmland crop, so there is still a risk of damaging crops or wasting water resources.

In view of the various shortcomings derived from the above conventional methods, embodiments of the present invention combine data analysis, network transmission, micro weather stations, water levels, water gate equipment monitoring and other technologies to provide real-time and intelligent water levels with data analysis Track sluice gate control methods to meet existing needs and overcome problems that conventional methods cannot overcome.

Figure 2 is a flow chart of a farmland irrigation method according to an embodiment of the present invention. Please refer to Figure 2. The water level monitoring units 13 distributed in each farmland 11 measure the water level height of the corresponding farmland 11. The data storage unit 15 regularly receives weather information (for example, temperature, humidity, illumination and wind speed) from the micro weather station monitoring unit 17 built on site through the network transmission unit 14, the sluice gate monitoring unit 12 located in each farmland 11, and Data sensed by the water level monitoring unit 13 (for example, the opening degree of the water gate, or other water gate status, the water level height of the farmland 11) (step S201). The control unit 10 provides the controlled farmland 11 filled in by the user on the input interface 16 and related information (for example, planting date, crop category, corresponding water gate, water level gauge) to the crop growth stage assessment module 18 (step S202) , to determine the growth stage of crops in farmland 11.

The crop growth stage module 18 can evaluate the growth stage based on the type of crop, planting date and weather information (step S203). For example, the crop growth stage module 18 can calculate the accumulated meteorological changes (changes related to temperature, humidity and/or illumination) from the date of application to the moment of execution and serve as meteorological information. The crop growth stage module 18 compares meteorological changes to one or more stage thresholds for that type of crop. Among them, multiple stages in the life cycle of different types of crops have different stage thresholds. The crop growth stage module 18 can determine the corresponding growth stage based on the comparison result with the stage threshold. For example, the crop growth stage module 18 determines which threshold of the highest growth stage the accumulated meteorological changes meet, which is the current growth stage of the crop (for example, rice cultivation, harvest season).

The crop growth stage module 18 provides the determined growth stage to the water demand assessment model 19 . The water demand evaluation model 19 determines the water demand corresponding to the growth stage (step S204). For example, the water demand assessment model 19 can derive different upper and lower limits of water levels (hereinafter referred to as the upper and lower limits of water demand) based on different crop types and different growth stages, and feed them back to the control unit 10 . For example, the upper and lower limits of water levels during the peak harvest period of rice cultivation are 8 cm and 3 cm.

The control unit 10 may compare the water demand and the water level height to generate a comparison result (for example, whether the water amount in the farmland 11 is lower than the lower limit of the water demand (step S205) or higher than the upper limit of the water demand (step S207)), and Generate gate control instructions based on the comparison results. If the comparison result is that the water level is lower than the lower limit of the water demand, the control unit 10 generates a gate control instruction related to water supply, so that the water supply gate opens and the water flows into the farmland 11 (step S206, that is, supplying water to the farmland 11). On the other hand, if the comparison result is that the water level is higher than the upper limit of water demand, the control unit 10 generates a gate control instruction related to water discharge and provides it to the water gate monitoring unit 12 through the network transmission unit 14, so that the water discharge gate opens and the water automatically The farmland 11 flows out (step S208, that is, water is discharged from the farmland 11). That is to say, when it is found that the water level of the farmland 11 is not within the upper and lower limits of the water demand, the water gate is controlled to complete the discharge or water supply to achieve the purpose of automatic irrigation. For example, if the water level in farmland 11 is 1 cm and less than the lower limit of water demand, the water supply gate is opened. Thereafter, the above water level comparison is repeated every 1 minute. When the water level reaches the upper and lower limits of water demand, that is, between 8 and 3 centimeters, the water supply gate is closed. Thereby, the water level of each managed farmland 11 is controlled to be consistent with the amount of water required by the crops in the farmland 11 during the growth stage.

To sum up, the farmland irrigation system and farmland irrigation method according to the embodiments of the present invention include the following features:

The embodiment of the present invention automatically evaluates the growth stage of farmland crops based on the date of crop application and local weather information. Calculate the amount of water required by crops through their growth stages and feed it back to water supply control. Compare the existing water differences in farmland, supply water when the farmland water is less than the water demand; release water when the farmland water exceeds the water demand. This saves irrigation water and manpower.

Embodiments of the present invention can solve the problem of managing a large amount of farmland that requires automatic irrigation for planting different crops at different times. Just define the farmland crops, planting dates, and water gates, and the system can automatically irrigate, so as to solve the problem of managing a large amount of farmland. It solves the problem of disorder and saves manpower time in managing a large amount of farmland.

Anyone with ordinary knowledge in the technical field may make some modifications and modifications without departing from the spirit and scope of the present invention. Therefore, The protection scope of the present invention shall be determined by the appended patent application scope.
