In a specific implementation manner of the embodiment of the invention, the sensor module comprises a multi-point distributed soil sensor and a soil monitoring unit;
the soil sensor obtains the pH value, the moisture content and the conductivity of soil in the plant greenhouse, and provides original data for formulation of a water-fertilizer irrigation strategy;
the soil monitoring unit processes data uploaded by the soil sensors, processes the data to obtain the condition of soil in the greenhouse, and reports the condition to the intelligent water and fertilizer all-in-one machine through the wireless acquisition gateway.
In embodiments of the invention, the water-fertilizer irrigation strategy comprises a water irrigation strategy and/or a fertilization strategy; when the water-fertilizer irrigation strategy is a water irrigation strategy and a fertilization strategy simultaneously, the water irrigation strategy is executed firstly, and then the fertilization strategy is executed, so that the fertilizer is prevented from being wasted due to the fact that the fertilizer cannot be absorbed by the plant root system along with infiltration of water after fertilization and watering. The water-fertilizer irrigation strategy comprises the beginning of execution time, the planned completion time, the duration of fertilizer effect after the completion of the execution, and the amount of nitrogen, phosphorus, potassium, trace elements and water in each square meter or each mu of irrigation.
And pushing the automatically generated water-fertilizer irrigation strategy to mobile control equipment (such as APP corresponding to the mobile phone) of an administrator for manual examination and execution after the examination is passed. The administrator can modify the water-fertilizer irrigation strategy during auditing, can check real-time greenhouse parameters at the mobile control equipment, and can add the water-fertilizer irrigation strategy once in a self-defined mode and execute the strategy when no strategy is to be audited. The irrigation safety is improved by presetting the primary irrigation threshold of water and fertilizer. For example, when the water-fertilizer irrigation strategy is automatically generated, and the water-fertilizer irrigation strategy modified or customized by the administrator exceeds a set threshold value, an early warning message is pushed to the administrator and waits for the confirmation of the administrator, or a reconfirmation prompt is added in the operation process, and the like. In the process of executing a watering strategy, water and fertilizer share a set of pipeline and directly reach the root area of crops. If the multi-point soil sensor comprehensively judges that the water content is higher than the set threshold value, the water irrigation is stopped; and if the moisture fed back by the soil sensor is lower than the set threshold value, triggering the generation of a next round of water irrigation strategy. The fertilization strategy is generated by processing a high-definition image of the plant growth to obtain the information of the plant species, the growth stage, the sizes, the colors, the pathological changes and the like of leaves and fruits of the plant, and then obtaining the fertilization strategy of nitrogen, phosphorus, potassium and trace elements by contrasting a plant fertilization model library. Taking a tomato as an example, the growth and development cycle of the tomato is divided into four stages, namely a germination stage (from seed germination to first true leaf emergence), a seedling stage (from first true leaf emergence to first big flower bud emergence), a flowering and fruit setting stage (from big flower bud emergence to first ear fruit setting) and a fruiting stage (from first ear fruit setting to expansion to fruit ripening), and some stages can be further subdivided. Firstly, obtaining the plant species, variety and current growth cycle through image processing or manual setting, and obtaining the fertilization strategy of nitrogen, phosphorus, potassium and trace elements through inquiring the data of a plant fertilization model base. Wherein the plant fertilization model base data is updatable by the mobile control device.
The following describes in detail the workflow of the water and fertilizer integrated optimization control system in the embodiment of the present invention with reference to fig. 2.
(1) Enabling an administrator to select whether to start intelligent identification, and further setting the image acquisition frequency of the high-definition monitor if the administrator selects to start intelligent identification; and if the plant is not started, the administrator manually sets the basic information of the plant. The manual setting in the process is considered for the situation that the plant images in the germination period and the seedling period of the plant are difficult to identify. Due to the slow growth speed of the plants, the collection frequency is defaulted to 8 hours and 1 time, and the administrator can set other frequencies. The basic information of the plant which is set for the first time comprises the type, the variety and the growth period of the plant, and is used for matching partial data of the plant fertilization model library to determine a primary fertilization scheme. And the later image identification comprises the plant species, the growth stage, the color and the state of plant leaves, the average number of flowers, the color and the size of fruits and the like, is used for judging whether the plant is drought or diseased, whether certain nutrient substances are lacked and the like, and provides a basis for formulating a fertilization strategy.
(2) And sending information such as image acquisition frequency for starting intelligent identification and administrator setting to an image processing unit of the monitoring module.
(3) The monitoring module collects the pictures of the plants in the greenhouse at multiple points according to the set or default collection frequency, so that the deviation of single-point identification is reduced. The pictures are processed by an image processing unit, and comprehensive plant data are obtained through image processing and mode identification.
(4) Judging whether the image recognition is finished in an image processing unit, if so, reporting the plant data to an intelligent water and fertilizer all-in-one machine according to a certain format as a basis of a water-fertilizer irrigation strategy; if the plant basic information cannot be identified, the administrator is informed to manually set the plant basic information.
(5) And the water and fertilizer control unit in the intelligent water and fertilizer all-in-one machine combines the soil information and the plant information uploaded by the acquisition sensor module and combines the comprehensive judgment of the matched fertilization model to generate a water-fertilizer irrigation strategy.
(6) The generated water-fertilizer irrigation strategy needs to be audited by an administrator, and after the audit is passed, the strategy is executed and the result is fed back to the mobile terminal; the administrator may refuse to execute or modify the execution of the policy.
(7) And after the implementation of the one-time water-fertilizer irrigation strategy is finished, judging whether the next water-fertilizer irrigation strategy generation is needed or not according to the soil information and the plant growth information fed back in real time. Triggering several conditions of water and fertilizer strategy generation: firstly, when the soil moisture is lower than or higher than a threshold value, a new strategy is generated when the soil moisture is lower than the threshold value, and the current water-fertilizer irrigation strategy is stopped when the soil moisture is higher than the threshold value; secondly, the effective duration time of the last fertilization is up; thirdly, the plant information is identified to be updated; fourth, the administrator adds a water-fertilizer irrigation strategy.
