2、搅拌装置采用将混合池中液体抽入混合泵后，经混合泵将液体从设置在混合池底部的喷嘴喷入混合池的方式进行搅拌，使得混合池中液体搅拌更加均匀。2. The mixing device uses the method of pumping the liquid in the mixing tank into the mixing pump, and then sprays the liquid into the mixing tank from the nozzle installed at the bottom of the mixing tank through the mixing pump, so that the liquid in the mixing tank is stirred more evenly.
3、混合泵可以为微型液体泵，指具备抽水口、排水口各一个，并且在进口处能够持续形成真空或负压，排水口处形成较大输出压力。因此每次使用无需加引导水能够自吸，排水口的液体能形成较大的冲击力，有利于液体的混合。3. The mixing pump can be a micro-liquid pump, which means that it has a suction port and a discharge port, and can continuously form a vacuum or negative pressure at the inlet, and form a large output pressure at the discharge port. Therefore, it can be self-absorbed without adding guiding water every time, and the liquid in the drain can form a greater impact force, which is beneficial to the mixing of liquids.
4、扇形喷嘴由于其独特的结构，扇形喷嘴在高压的作用下，喷射出来的液体具有极大的冲击力。在这种冲击力的作用下，不仅有利于营养液的混合，还能避免池底形成沉积物，还能把混合池的污垢清洗干净。4. Fan-shaped nozzle Due to its unique structure, the liquid ejected from the fan-shaped nozzle has a great impact under the action of high pressure. Under the action of this impact force, it is not only beneficial to the mixing of the nutrient solution, but also avoids the formation of sediment at the bottom of the pool, and can also clean the dirt in the mixing pool.

本实施例中，取5个样品来检测一个检测点的土壤水分、全氮、有效磷、有效钾的含量，其中每组样品中，在检测点上取1个样品，在该检测点附近与检测点距离相等的圆上均匀取4个样品，这样的检测结果不单单只是体现了处于中心检测点位置处的土壤养分缺失的情况，而是体现了中心检测点周边区域的整体养分缺失情况，这样提高了检测结果的普遍性、适用性和真实性。当土壤检测模块检测到该土壤中某养分的含量低于植物正常生长的含量时，为了保证植物正常生长，就需要给土壤补充对应的养分。例如当土壤中全氮含量过低时，就需要让土壤中补充氮肥，便控制装有氮肥的营养液储蓄箱的阀门打开，使得氮肥加入混合池中。其中不同的种类或成长期的植物需要的养分含量不同，数据分析单元中可以预设有不同种类或成长期下植物所需养分的含量，当开启该系统检测土壤养分时，可以输入植物的类别和成长期，这样该数据分析单元便可以根据不同种类或成长期的植物来补充土壤所需的养分，适用性更广。同一种营养液存储在同一个营养液储蓄箱中，这样能更加准确地控制加入混合池中的养分含量。In this embodiment, 5 samples are taken to detect the content of soil moisture, total nitrogen, available phosphorus, and available potassium at a detection point, wherein in each group of samples, 1 sample is taken at the detection point, and it is close to the detection point. Take 4 samples evenly on a circle with the same distance between the detection points. Such detection results not only reflect the lack of soil nutrients at the central detection point, but also reflect the overall nutrient deficiency in the surrounding area of the central detection point. This improves the universality, applicability and authenticity of the detection results. When the soil detection module detects that the content of a certain nutrient in the soil is lower than the normal growth content of the plant, in order to ensure the normal growth of the plant, it is necessary to supplement the corresponding nutrient to the soil. For example, when the total nitrogen content in the soil is too low, it is necessary to supplement the nitrogen fertilizer in the soil, so that the valve of the nutrient solution storage tank with nitrogen fertilizer is controlled to be opened, so that the nitrogen fertilizer is added to the mixing tank. Different types or growth stages of plants require different nutrient content. The data analysis unit can preset the nutrient content required by plants of different types or growth stages. When the system is turned on to detect soil nutrients, the type of plant can be input and growth period, so that the data analysis unit can supplement the nutrients required by the soil according to different types or growth periods of plants, and has wider applicability. The same nutrient solution is stored in the same nutrient solution storage tank, which can more accurately control the nutrient content added to the mixing tank.
各种营养液和水加入混合池中进行混合后，在通过增压泵压入喷头中，对土壤进行灌溉，所以混合池的基本要求就是能够将液体搅拌均匀，这样才能保证喷洒的液体富含有各种养分。营养液储蓄箱中的液体通过注入管注入混合池中，注入管中阀门打开时，营养液储蓄箱中的液体便加入至混合池中，注入管中阀门关闭时，停止向混合池中加入营养液。该系统中设有存有水的营养液储蓄箱，一方面用于给土壤补充水分，另一方面用于稀释营养液浓度。After adding various nutrient solutions and water into the mixing tank for mixing, they are pressed into the nozzle by the booster pump to irrigate the soil. Therefore, the basic requirement of the mixing tank is to be able to stir the liquid evenly, so as to ensure that the sprayed liquid is rich in There are various nutrients. The liquid in the nutrient solution storage tank is injected into the mixing tank through the injection pipe. When the valve in the injection pipe is opened, the liquid in the nutrient solution storage tank is added to the mixing tank. When the valve in the injection pipe is closed, the feeding of nutrients into the mixing tank is stopped. liquid.

所述搅拌装置包括抽水管16、混合泵14、排水管17和喷嘴18；喷嘴18设置在所述混合池11的底部且朝上设置，抽水管16一端伸入所述混合池11中水位下方，另一端连接至混合泵14的进水端，混合泵14的出水端连接至排水管17的一端，排水管17的另一端伸入混合池中与喷嘴18连接，混合泵用于将从进水端进入的液体从出水端压出后，从喷嘴喷出。还包括水泵控制器13，水泵控制器13用于控制混合泵14和增压泵15的启动或关闭。Described agitating device comprises suction pipe 16, mixing pump 14, drainage pipe 17 and nozzle 18; Nozzle 18 is arranged on the bottom of described mixing tank 11 and is arranged upwards, and one end of suction pipe 16 stretches below the water level in described mixing tank 11 , the other end is connected to the water inlet end of the mixing pump 14, and the water outlet end of the mixing pump 14 is connected to one end of the drain pipe 17, and the other end of the drain pipe 17 stretches into the mixing tank and is connected with the nozzle 18, and the mixing pump is used to convert the After the liquid entering the water end is pressed out from the water outlet, it is sprayed out from the nozzle. A water pump controller 13 is also included, and the water pump controller 13 is used to control the start or stop of the mixing pump 14 and the booster pump 15 .
现有的搅拌装置基本为设置在混合池内的搅拌叶轮，通过电机控制搅拌叶轮转动进行搅拌，这种搅拌方式对于容量比较大的溶液来说具有以下缺点：1、搅拌不够均匀，该方法只能对搅拌叶轮附近的溶液进行搅拌。2、电机耗电量比较大。为此本实施例中提出了上述搅拌装置，混合泵可以将混合池中的液体抽入混合泵中进行一级混合后，压入排水管，使得一级混合后的液体能够从设置在混合池底部的喷嘴喷出，喷出的液体继续保持向上的运动状态，和喷嘴上方的液体混合搅拌，完成二级混合。搅拌装置通过抽水管抽液、排水管排液，再通过喷嘴将混合液喷出，最后回到混合池，在抽排的循环作用下，达到将混合液混合均匀的目的，搅拌更加均匀。混合泵可以为微型液体泵，微型液体泵具备抽水口、排水口各一个，并且在进水端能够持续形成真空或负压，排水端形成较大输出压力。因此每次使用无需加引导水能够自吸，排水端的液体能形成较大的冲击力，有利于液体的混合。The existing stirring device is basically the stirring impeller arranged in the mixing tank, and the stirring impeller is controlled by the motor to rotate. This stirring method has the following disadvantages for the solution with a relatively large capacity: 1. The stirring is not uniform enough. This method can only The solution near the impeller is stirred. 2. The power consumption of the motor is relatively large. For this reason, the above-mentioned mixing device is proposed in this embodiment. The mixing pump can pump the liquid in the mixing tank into the mixing pump for primary mixing, and then press it into the drain pipe, so that the liquid after the primary mixing can be discharged from the mixing tank. The nozzle at the bottom sprays out, and the sprayed liquid continues to maintain an upward motion state, and mixes with the liquid above the nozzle to complete the secondary mixing. The mixing device draws liquid through the water pipe, discharges the liquid through the drain pipe, and then sprays the mixed liquid through the nozzle, and finally returns to the mixing tank.

The micro-liquid pump has a suction port and a discharge port, and can continuously form a vacuum or negative pressure at the water inlet, and form a relatively large output pressure at the discharge end. Therefore, it can be self-absorbed without adding guiding water every time, and the liquid at the discharge end can form a greater impact force, which is beneficial to the mixing of liquids.
所述排水管通过过滤器与喷嘴连接。过滤器主要用于过滤从排水管流进喷嘴中液体中存在的颗粒，为了防止大量颗粒流向喷嘴堵塞喷嘴。所述喷嘴为扇形喷嘴。扇形喷嘴由于其独特的结构，扇形喷嘴在高压的作用下，喷射出来的液体具有极大的冲击力。在这种冲击力的作用下，不仅有利于营养液的混合，还能避免池底形成沉积物，还能把混合池的污垢清洗干净。The drain pipe is connected with the nozzle through a filter. The filter is mainly used to filter the particles present in the liquid flowing into the nozzle from the drain pipe, in order to prevent a large number of particles from flowing to the nozzle to block the nozzle. The nozzles are fan nozzles. Due to its unique structure, the fan-shaped nozzle sprays liquid with great impact under the action of high pressure. Under the action of this impact force, it is not only beneficial to the mixing of the nutrient solution, but also avoids the formation of sediment at the bottom of the pool, and can also clean the dirt in the mixing pool.

After the detection data of the meter, it is judged whether the data reaches the preset liquid level safety height, and if so, an alarm is issued. In this way, when the water level in the nutrient solution storage tank is too high, an alarm is given to prompt relevant staff to stop adding liquid to the nutrient solution storage tank. Similarly, the inner wall of the mixing tank is also provided with a second liquid level gauge 12, the second liquid level gauge 12 is connected to the control unit 5 of the main processing module, and the second liquid level gauge is used to detect the liquid water level in the mixing tank, The detection data is transmitted to the control unit, and the control unit is used to judge whether the data reaches the preset safety height after receiving the detection data from the second liquid level gauge, and to issue an alarm if it reaches the preset safety height. When the liquid level in the mixing tank is too high, an alarm is also issued to prompt relevant staff to stop adding liquid to the mixing tank.
雨水过滤模块主要用于将雨水过滤后形成可用于灌溉的水分，用于给土壤灌溉。需要过滤的主要成分有颗粒、硫等有害物质。本实施例中的雨水过滤模块采用了两级过滤方法：在雨水采集模块进行第一级过滤，所述雨水采集模块包括弯曲的输水管道，输水管道的弯折处具有连通外界的排沙孔，排沙孔的孔径为0.4mm，输水管道与所述雨水过滤器入口连接，这样，雨水在流向雨水过滤器之前，雨水带有的颗粒就会沉积在输水管道的弯折处，并通过排沙孔排向外界，完成第一级过滤。然后在流向雨水过滤器完成第二级过滤。The rainwater filtration module is mainly used to filter rainwater to form water that can be used for irrigation, which is used to irrigate the soil. The main components that need to be filtered are harmful substances such as particles and sulfur. The rainwater filtration module in this embodiment adopts a two-stage filtration method: the first-stage filtration is carried out in the rainwater collection module. hole, the pore diameter of the sand discharge hole is 0.4mm, and the water delivery pipe is connected with the inlet of the rainwater filter, so that before the rainwater flows to the rainwater filter, the particles carried by the rainwater will be deposited at the bend of the water delivery pipe, And discharge to the outside through the sand discharge hole to complete the first stage of filtration. The second stage of filtration is then completed by flowing to the stormwater filter.
一种植物土壤营养液自动补给方法，在上述的植物土壤营养液自动补给系统上运行，包括如下步骤：A method for automatically replenishing plant soil nutrient solution, operating on the above-mentioned automatic replenishment system for plant soil nutrient solution, comprising the following steps:

所述步骤S3具体为：The step S3 is specifically:
S3a)数据分析单元中预存有各个营养液储蓄箱中营养液浓度值Ci；其中i取值为1～j，j为需要补给的营养液的个数，j小于等于营养液储蓄箱的个数；S3a) The data analysis unit pre-stores the nutrient solution concentration value C i in each nutrient solution storage box; where i takes a value from 1 to j, j is the number of nutrient solutions that need to be replenished, and j is less than or equal to the number of nutrient solution storage boxes number;
S3b)数据分析单元根据接收到的来自土壤检测模块的数据，计算得到该土壤中需要补给的营养液以及补给的原液体积Pi，并根据需要补给的营养液浓度值Ci以及原液体积Pi,计算得到需要补给的营养液的补给体积Vi，其中Vi＝Pi/Ci；S3b) The data analysis unit calculates the nutrient solution that needs to be replenished in the soil and the volume of the stock solution P i that needs to be replenished according to the data received from the soil detection module, and the concentration value of the nutrient solution that needs to be replenished C i and the volume of the stock solution P i , calculate the supply volume V i of the nutrient solution that needs to be supplied, where V i =P i /C i ;

本实施例提供的营养液添加方法，通过数据分析单元计算阀门开启的时间，来控制阀门的打开和关闭，可以准确的补给土壤所缺养分的含量，操作简单。具体实施时，原液是指养分浓度高的营养液，浓度大于90％，其含有的水分可以忽略不计。营养液的补给体积Vi表示的是需要增加的养分的体积。营养液储蓄箱中注入管的截面Si可以直接测量得到，流速Li可以根据具体情况进行设定。具体实施时，控制模块需要设置个数和开启的营养液储蓄箱阀门个数相同的计时器，每个计时器用于检测每个营养液储蓄箱阀门开启的时间，当营养液储蓄箱阀门打开时，对应的计时器进行计时，当计时器计时到达该营养液储蓄箱阀门开启时间Ti，计时器停止计时，并触发控制单元关闭该营养液储蓄箱阀门。The nutrient solution addition method provided in this embodiment controls the opening and closing of the valve by calculating the opening time of the valve through the data analysis unit, which can accurately supply the nutrient content lacking in the soil, and is easy to operate. During specific implementation, the stock solution refers to a nutrient solution with high nutrient concentration, the concentration is greater than 90%, and the water contained in it can be ignored. The replenishment volume V i of the nutrient solution represents the volume of nutrients that need to be added. The section S i of the injection pipe in the nutrient solution storage tank can be directly measured, and the flow rate L i can be set according to specific conditions. During specific implementation, the control module needs to set the same timer as the number of valves of the nutrient solution storage tank that is opened, and each timer is used to detect the opening time of the valve of each nutrient solution storage tank. When the valve of the nutrient solution storage tank is opened , the corresponding timer counts, and when the timer reaches the opening time T i of the nutrient solution storage tank valve, the timer stops timing and triggers the control unit to close the nutrient solution storage tank valve.
本实施例还提供营养液稀释的功能，所述步骤S3c中，数据分析模块除了需要计算得到营养液需要补给的体积后，还需要计算得到稀释营养液需要的水分。灌溉的液体中营养液的浓度不宜过高或过低，过高会造成营养液不能完全被吸收，造成养分浪费。过低会导致养分补给不足。数据分析单元中还可以预设有适合植物生长的灌溉液体的浓度，数据分析单元根据所加入的营养液原液体积和适合植物生长的灌溉液体的浓度，计算得到需要加入水分的体积(需要加入水分的体积等于加入的营养液原液体积除以适合植物生长的灌溉液体的浓度)，数据分析单元还用于计算得到营养液添加过程中水的补给体积A，根据装有水的营养液储蓄箱中注入管的截面B以及流速D，计算得到该营养液储蓄箱阀门开启时间E，其中E＝A/(B×D)，并通过步骤S4的方法控制水分的加入。This embodiment also provides the function of diluting the nutrient solution. In the step S3c, the data analysis module not only needs to calculate the volume of the nutrient solution to be replenished, but also needs to calculate the water required to dilute the nutrient solution. The concentration of the nutrient solution in the irrigation liquid should not be too high or too low. If it is too high, the nutrient solution cannot be completely absorbed, resulting in waste of nutrients. Too low will result in insufficient nutrient supply. The concentration of the irrigation liquid suitable for plant growth can also be preset in the data analysis unit, and the data analysis unit calculates the volume of water that needs to be added according to the volume of the added nutrient solution stock solution and the concentration of the irrigation liquid suitable for plant growth (need to add water The volume is equal to the added nutrient solution stock solution volume divided by the concentration of irrigation liquid suitable for plant growth), the data analysis unit is also used to calculate the replenishment volume A of water in the nutrient solution addition process, according to the nutrient solution storage tank with water The section B of the injection pipe and the flow rate D are calculated to obtain the opening time E of the valve of the nutrient solution storage tank, where E=A/(B×D), and the addition of water is controlled by the method of step S4.
