Description

Automatic batching and managing spraying system

Technical Field

The invention relates to the field of agriculture, in particular to a system for helping a user to automatically prepare pesticides and carry out intelligent spraying management.

Background

The pesticide residue exceeding the standard is one of the main reasons of food failure. The pesticide residue exceeds the standard mainly because the pesticide spraying is not standard and unreasonable. The pesticide spraying is not standard, and mainly shows that the proportion concentration of the pesticide is unreasonable, the spraying amount is not matched with the area of the planting land, the pesticide spraying time conflicts with the harvest time of agricultural products, the quality of the pesticide is not excessively related, and the like. The unreasonable pesticide spraying is mainly characterized in that the used pesticides do not accord with the pesticides required by crops, and the mixed use of various pesticides produces adverse effects.

Currently, the means of spraying the pesticide is an agricultural sprayer. An agricultural sprayer generally includes a liquid tank for containing a pesticide liquid, a water pump connected to the liquid tank, and a spray head connected to the water pump. The pesticide liquid in the liquid tank needs to be manually selected according to planted crops, then the pesticide liquid is manually configured, finally the configured pesticide liquid is filled into the liquid tank, and the configured pesticide liquid is sprayed onto the crops planted in the field through an agricultural sprayer.

However, since many farmers have limited knowledge of pesticides, selection of pesticides is prone to errors, which not only cannot help crops to prevent and control plant diseases and insect pests, but also easily increases unnecessary pesticide residues due to wrong pesticides. Meanwhile, an effective means is lacked at present, so that each farmer can correctly judge whether the pesticide is overdue or not and whether the pesticide is a counterfeit product or not, and if the pesticide is deteriorated due to overdue or counterfeit, unpredictable harm is often caused.

More importantly, the existing agricultural sprayer needs farmers to prepare the pesticide liquid according to experience, and the farmers are difficult to master the concentration of the actually prepared pesticide liquid. And the total amount of the pesticide liquid required by different field areas is different, so that farmers are difficult to prepare the required amount at one time successfully, if too much pesticide is prepared, the pesticide is wasted, and if too little pesticide is prepared, the pesticide needs to be prepared again to meet the field requirements.

In addition, the pesticide spraying time is also the operation of farmers according to own experience, and if the pesticide spraying time is too late, a large amount of pesticide still remains on the pesticide when the crops are picked, so that harm is possibly brought to eaters.

In view of this, there is a need for an automatic dispensing and managing spraying system, which can guide farmers from selection, dispensing to spraying of pesticides, so that the farmers can accurately and reasonably spray pesticides according to actual varieties of planted crops and actual field sizes, thereby not only playing a role in controlling crop diseases and insect pests, but also effectively reducing pesticide residues.

Through the collection end, pathological characteristics and field area of crops are described through characters or pictures and then are sent to the intelligent agricultural platform. Meanwhile, the identification code on the pesticide packaging bag is scanned through the acquisition end and is transmitted to the intelligent agricultural platform.

The intelligent agricultural platform comprises a database for storing common agricultural knowledge in the field and a central processing unit for calling the stored content in the database. The central processor is connected with the acquisition end and the agricultural sprayer through a network connection module connected with the central processor.

Various pesticide standard identification codes are stored and periodically updated in the database, and whether the pesticide currently prepared for use by a farmer is a genuine product and is in the effective period can be judged by comparing the pesticide identification code transmitted by the acquisition terminal with the pesticide standard identification code.

Storing and regularly updating the pest and disease picture and pest character description of various crop pests in the database, and if the picture is transmitted to the intelligent agricultural platform by the acquisition end, comparing the current crop description picture with the pest and disease picture to find out the corresponding pest and disease picture stored in the database; and if the character information is transmitted by the acquisition end, comparing the current crop character description with the pest character description, and finding out the corresponding pest character description stored in the data. After determining the specific pest of the current crop, pesticide information stored in a database for dealing with the pest is found. And the central processing unit extracts pesticide information from the database and sends the pesticide information to the acquisition end, so that the farmers can see the pesticides which need to be purchased and used by the farmers through the acquisition end.

Meanwhile, an area usage conversion table is stored in the database, and the usage of different pesticides required when fields with different areas correspond to different crops is recorded. The central processing unit obtains the corresponding pesticide usage amount according to the field size and the crop information transmitted by the acquisition end and the area usage amount conversion table, and sends the pesticide usage amount to the acquisition end and the agricultural sprayer. The amount of the pesticide liquid required to be prepared can be visually seen by a farmer through the collecting end, and the farmer can be helped to complete the preparation of the pesticide liquid with the total amount and the concentration through the sprayer.

As shown in fig. 2, the agricultural sprayer includes a liquid tank 3 for mixing a pesticide and water to form a pesticide liquid, and a multi-stage spray head 4 connected to the liquid tank 3 for spraying the pesticide liquid outwardly. The top end of the liquid tank 3 is opened with an opening for supplying water and agricultural chemicals into the liquid tank 3, and the opening is covered with a first cover 10 for covering the opening.

When the liquid tank 3 is used for preparing the pesticide liquid, water is added to the liquid tank 3 first, and then the pesticide is added to the liquid tank 3.

A level sensor 13 for detecting the amount of added water and the amount of the agricultural chemical liquid after blending is installed in the liquid tank 3. The liquid level sensor 13 detects the amount of water added to the liquid tank 3 and the amount of the pesticide liquid after blending by the prior art through the level of the liquid level.

In order to more accurately guide the farmer to carry out pesticide liquid blending operation, the collecting end guides the farmer to sequentially add M liters of water and N kilograms of pesticides into the liquid tank 3 in a voice broadcasting or image-text display mode, and the specific numerical values of M and N are different according to the size of the land to be fertilized and the different types of the pesticides.

The first cover 10 is provided with an intelligent lock for locking the first cover 10 to prevent the first cover from being opened randomly, and the intelligent lock can be an electromagnetic lock commonly used at present. Only when the agricultural atomizer receives the start signal of the agricultural platform of intelligence or collection end after, the intelligence lock just can be opened, and the peasant household can open first case lid 10, adds water and pesticide in proper order through the opening and carries out the pesticide allotment in liquid tank 3.

Further, the outer surface of the liquid tank 3 or the outer surface of the first cover 10 is coated with a nebulizer identification code. Each sprayer identification code corresponds to one agricultural sprayer one by one, and the sprayer identification code is a unique identification code. The acquisition end establishes a network connection relation with the agricultural sprayer through scanning and identifying the sprayer identification code. The sprayer identification code in this embodiment is a two-dimensional code.

The multi-stage sprayer 4 is provided with a plurality of gears for enabling the sprayer to have different flow rates, and the central processing unit controls the sprayer to select the gear sprayer with a proper grade according to field size information so as to control the flow rate of the liquid sprayed with pesticide.

In the embodiment, the pathological feature text description of the crops is input or the diseases and insect pests of the crops are shot to form pictures which are sent to the intelligent agricultural platform, and the intelligent agricultural platform recommends the pesticide to the peasant household according to the contents stored in the database.

In this embodiment, a farmer only inputs part of apparent data, such as plant types, diseases or insect pests, which occur in new leaves or old leaves, stems or roots, and the like, because many things of the farmer cannot be described clearly at once, the platform forms an option for the farmer to select by sending pictures or characters to the acquisition end, helps the farmer to narrow the description range step by step, finds out typical picture features of the insect pests, enables the farmer to select the typical picture features by contrast, confirms specific situations such as types of the current crop insect pests and the like, enables the farmer to correctly describe current crop insect pests under the guidance of the acquisition end and the intelligent agricultural platform, and forms current crop data which can be recognized by the acquisition end and the intelligent agricultural platform.

This embodiment enables the peasant household and enough after purchasing the pesticide, shoots the identification code on the pesticide packing through the collection end and transmits for intelligent agricultural platform, and whether this pesticide is effective is judged through discernment to intelligent agricultural platform, and the case lid of atomizer is then opened to the pesticide is effective, makes the peasant household can pour into liquid case 3 with water and pesticide in proper order.

This embodiment sends for the agricultural platform of intelligence through gathering end input field area size and the crops of planting, and the agricultural platform of intelligence converts out pesticide liquid use amount, concentration and sprays the velocity of flow and send for the atomizer. The atomizer passes through level sensor 13 and detects the water yield of adding in liquid tank 3, detects the total amount of allotment back pesticide through level sensor 13 equally after adding the pesticide, can detect and monitor whether the volume of whole pesticide liquid allotment prepares through level sensor 13, and then makes central processing unit can judge whether the pesticide liquid concentration of allotment meets the requirements. Of course, in order to guide the farmer to prepare the pesticide more accurately, other sensing devices such as a weight sensor and a flow sensor may be installed in the liquid tank 3. Meanwhile, the sprayer selects a spraying flow rate suitable for the grade by changing the flow cross section area in the multi-stage sprayer 4.

In addition, other information such as season information, position information can also be input to the agricultural platform of intelligence through the collection end to this embodiment, makes the agricultural platform of intelligence for the pesticide that peasant household recommended more accurate, is fit for current crops more and uses.

The specific implementation process is as follows:

the intelligent agricultural platform mainly comprises a database and a central processing unit for calling the database, wherein the central processing unit is connected with the acquisition end and the agricultural sprayer through a network connection module.

As shown in fig. 3, the architecture of the intelligent agricultural platform sequentially includes a basic data layer composed of a database and the like, a system calling layer composed of a pesticide selection module, a proportioning module and an interval management module in a central processing unit, and an application acquisition layer composed of a network connection module.

One, basic data layer

The basic data layer is mainly composed of a database, agricultural basic data are stored in the database in advance, and meanwhile, new agricultural basic data are continuously acquired and supplemented through a network connection module connected with the acquisition end and the agricultural sprayer.

Agricultural basic data mainly comprises data of crops, insect pests, diseases, pesticides and pesticide residues.

Wherein, the crop data comprises attributes such as species, drought tolerance or water preference, seasons suitable for planting and growing, and the like;

pest data including attributes of pest species, seasonality, habit preferences, parasitism, pest performance and affectivity;

disease data including attributes such as disease expression, category, occurrence part, grade size, seasonality, water cold condition and the like;

pesticide data including attributes such as pesticide type, corresponding dosage, use, efficacy, usage, climate, and the like;

pesticide residue data includes attributes such as after-use performance, residue condition and measures.

The attributes are recorded in a text format, and meanwhile, image forms are added to attribute items such as crop types, pest manifestations, disease manifestations, occurrence parts, pesticide types, pesticide after-manifestation and the like for recording.

Since each piece of data starts with the name of each piece, there is no possibility that the attribute items conflict. And for the same crop, the crop data, the insect pest data, the pesticide data and the pesticide residue data of the same crop are related to each other through the agricultural basic data information table.

When data acquisition and storage are carried out on each specific crop, keyword remarks are carried out according to all the attributes and then the data are stored in a database, and a central processing unit can accurately match and call information conveniently.

Second, system calling layer

The system calling layer mainly comprises a pesticide selection module, a proportioning module and an interval period management module in the central processing unit. The pesticide selection module, the proportioning module and the interval management module call data of corresponding attribute items in the database according to specific performances and characteristics of insect pests and diseases, current crop data received from the acquisition end are compared with standard crop data stored in the database, standard crop data closest to the current crop data are found, data of corresponding attribute items in the standard crop data are extracted, a complete data chain is formed, and a scientific agricultural solution is provided.

The interval management module is used for timing pesticide spraying time from the beginning of spraying pesticide liquid for each region of crops; when the pesticide spraying time is longer than the pesticide safety interval period, the central processing unit marks the crops in the area as the harvestable crops.

The half-life refers to an important time node of pesticide metabolic residue, and after the half-life, the pesticide is basically free of residue. Through interval management module, all crops that spray insecticide in every region carry out the pesticide and spray time management, avoid picking the crops of pesticide residue.

For crops needing to be continuously applied with pesticides, tracking and recording current crop data sent by the same acquisition end at the same position by an interval management module; meanwhile, the interval management module tracks and records the time of signal feedback of the pesticide selection module and the proportioning module aiming at the current crop data, and takes the feedback time as the time of the previous pesticide application; for each pesticide, the interval period management module directly or indirectly controls the multi-stage spray heads 4 to be opened through the acquisition end only after the current pesticide application time is longer than the preset interval time of the interval period management module from the current time. The current crop data collected by the collecting end is used for accurately recording pesticide application time, interval period management is carried out according to the data of the interval periods in the database, and the problem of food safety caused by large pesticide residue due to the fact that agricultural products are picked in advance is solved.

Specifically, the pesticide selection module selects the attribute items and the same crop data transmitted by the acquisition end from the database through character description or image description of pest names, disease names, damage degrees, total areas, damage areas, historical pesticides, weather conditions, crop names, the season of the crop and the damaged part, which are transmitted by the acquisition end, and transmits the data of the attribute items to the network connection module of the application acquisition layer according to the data of other attribute items corresponding to the crop data in the crop data information table. Meanwhile, the proportion module sends the proportion and the dosage of the pesticide and the water to the network connection module.

In addition, the pesticide selection module and the proportioning module transmit the same data to the interval management system while transmitting the data to the network connection module. And the system calling layer randomly generates a time serial number according to the prior art when calling the content in the database each time, and the time serial number is unique. The corresponding time serial number of the problem description of one acquisition end is unique, namely the acquisition end which accesses the same account number at the same time in the same field is accessed. Meanwhile, the acquisition end also sends a real-time position signal when accessing the platform, and a farmer can access the platform through the account number registered by the acquisition end. Therefore, for one account, all the processing data for the account in the platform is carried with the time serial number, the position signal and the account number, so that the interval management module can record and manage the pesticide application time of each field. The interval management module is enabled to send the administration information to the network connection module at the next time of administration.

The specific setting of the interval period may be changed according to the use scene of the farmer, and in this embodiment, the interval period is set as a pesticide safety interval period.

Thirdly, applying an acquisition layer

The application acquisition layer is mainly composed of a network connection module. The platform is respectively connected with the acquisition end and the agricultural sprayer through the network connection module.

The network connection module is connected with the acquisition end, and receives the current crop data which is sent by the acquisition end and contains one or more attribute items, such as crop names, pest names, crop pictures, pest pictures, affected areas, affected degrees and the like, and describes the disease course. The network connection module also receives pesticide residue records input through the acquisition end from the acquisition end. Meanwhile, the network connection module receives information transmitted by the pesticide selection module in the system calling layer and sends matched specific plant diseases and insect pests and recommended pesticide and dosage to the acquisition end. The recommended pesticide and the dosage can be seen by farmers through collection terminals such as mobile phones.

The network connection module is connected with the agricultural sprayer, receives the information transmitted by the proportioning module, sends information such as control proportioning, control dosage, spray nozzle size and sprinkling area to the agricultural sprayer, and guides farmers to complete pesticide preparation and sprinkling operation by utilizing the sprayer. For this embodiment, the smart lock on the first cover 10 of the agricultural sprayer and the level sensor 13 in the liquid tank 3 can be controlled by the central processor directly through the network connection module according to the prior art, and the acquisition end can also directly control the electronic devices on the agricultural sprayer through the network connection device on the acquisition end. Therefore, when the intelligent agricultural platform or the collection end sends the control proportion and the control dosage to the agricultural sprayer, the intelligent lock is opened, and the collection end guides a farmer to sequentially add water and pesticides into the liquid tank 3 according to the ration. In the process of preparing the pesticide liquid, the result detected by the liquid level sensor 13 is fed back to the intelligent agricultural platform or the pesticide liquid preparation condition at the acquisition end, so that the intelligent agricultural platform or the acquisition end can guide farmers to stop the action of continuously adding water or pesticide to finish the pesticide liquid preparation work. Generally speaking, after a farmer adds water and pesticide into the liquid tank 3, the collection terminal or the intelligent agricultural platform guides the farmer to stir the pesticide liquid in the liquid tank 3 after 1-3 minutes, and the whole pesticide liquid preparation work is completed after the stirring is carried out for about 1 minute.

And multistage shower nozzle 4 can directly be controlled by central processing unit or collection end equally according to prior art, and central processing unit or collection end direct control multistage shower nozzle 4 adjustment shower nozzle velocity of flow size, and then the adjustment sprays the area.

In addition, in order to enable the agricultural sprayer to operate according to the control of the proportioning module, the pesticide selection module is required to firstly identify that the currently used pesticide is consistent with the pesticide to be used in the field recorded in the database, generally, the names of the pesticides are compared through texts, and the identification code on the outer package of the currently used pesticide is identified to judge whether the currently used pesticide is effective. And judging the interval period through an interval period management module only under the condition that the current pesticide is correct and effective. For the agricultural sprayer, because the agricultural sprayer is connected with the platform and is bound with the account number of the acquisition end, the data of the acquisition end and the data of the agricultural sprayer are basically shared in one spraying operation, and all the data have the same prefix, namely the time sequence number, the position signal and the account number. Therefore, for the application time corresponding to the same account of the same position signal, the interval period management module can record and easily calculate the interval according to the prior art. Pesticide residue conditions of each pesticide in each time period are stored in the interval management module in advance. Only when detecting that the pesticide residue in the field to be applied with pesticide reaches the safety value, the pesticide residue after picking is not influenced, namely the crop growth is not influenced, and the interval management module can unlock the spray head of the agricultural sprayer so that the spray head can spray pesticide liquid.

The embodiment takes the existing big data and artificial intelligence technology as support, and combines software and hardware to form intelligent agricultural management. Specifically, the pathological features of crops are input by using a mobile phone loaded with APP, the pathological features of the crops are sent to an intelligent agricultural platform, the intelligent agricultural platform finds related information by comparing and matching crop data with the same pathological features of the input crops, and the system intelligently provides an optimal solution. Then carry out the farming setting according to the solution that provides, agricultural intelligent platform can directly link to each other with agricultural atomizer and carry out direct operation control, also can send relevant operation information for the cell-phone of installing APP, carries out manual operation through the cell-phone. If the mobile phone is operated, the APP is used for being connected with the sprayer in the prior art, and the APP is used for controlling and adjusting valves of all parts of the sprayer, so that scientific farming management is achieved. And moreover, the pesticide content and the interval period of the crops are intelligently calculated through the record of pesticide application of the crops, and the agricultural guidance is scientifically provided, so that the food safety is ensured.
