Referring to fig. 1 and 2, an embodiment of the present application provides an aspect of an embodiment that discloses a planter, including:

planter main part 100, planter main part includes a plurality of water planting unit 110, unit 110 is planted including the cavity that is used for holding the culture solution to the water planting. In some embodiments, the hydroponic planting unit 110 is provided with a plurality of planting grooves 111, the planting grooves 111 are distributed in a matrix, and the planting grooves 111 are used for limiting the position of the plants. In some embodiments, the planter body 100 includes a plurality of hydroponic planting units 110, and the plurality of hydroponic planting units 110 are arranged in layers along the height direction of the planter body 100. Specifically, this scheme can adopt open planter main part, and convenience of customers gets from all directions like this and puts the plant. The open type main body is adopted, so that the plants do not need to be ventilated through ventilation equipment, and the complexity of the planter is simplified. In a water planting unit, each planting groove is communicated with a cavity for bearing a culture solution, and plants can directly absorb nutrients from the planting grooves.

And the circulating pump is used for driving the culture solution in the cavity to circulate. A circulation loop is formed between the circulating pump and the water planting unit, so that the culture solution is circulated. In the circulation loop, a portion of the nodes may be placed in the circulation to administer nutrients. For example, by providing a culture solution mixing chamber in the circulation circuit and circulating the culture solution between the culture solution mixing chamber and the hydroponic planting unit by the circulation pump, the nutrient content in the culture solution can be made uniform. Of course, in some embodiments, the circulation pump may be only internally circulated. Each water planting unit is provided with a nutrient feeding module, and in such an embodiment, each water planting unit can plant different plants. It will be appreciated that in the planter, there is also provided a means for replenishing the culture solution, which may be a specific solution or may be ordinary water.

And the culture solution state sensor group is used for detecting the chemical state of the culture solution. Wherein, the culture solution state sensor group comprises a PH value sensor, a nitrogen sensor, a phosphorus sensor and a potassium sensor. Of course, the culture solution status sensor group in some embodiments further includes a sensor such as an oxygen content sensor. The pH value sensor is mainly used for detecting the pH value of a culture solution, and the pH value is an important index for plant cultivation. The nitrogen sensor, the phosphorus sensor and the potassium sensor can be realized by adopting an integrated nitrogen-phosphorus-potassium sensor, and are mainly used for detecting the content of nitrogen element, phosphorus element and potassium element in the culture solution. Nitrogen, potassium and phosphorus play an important role in the plant growth process.

And the nutrient substance feeding module is used for feeding nutrient substances to the culture solution. The nutrients are mainly fertilizers for providing nitrogen, potassium and phosphorus elements and chemical components for adjusting the pH value of the culture solution, and are usually in liquid form. In some embodiments, the nutrient feeding module includes a potassium nutrient feeding unit, a nitrogen nutrient feeding unit, a phosphorus nutrient feeding unit, an acidic substance feeding unit, and an alkaline substance feeding unit. In these embodiments, the various nutrients are stored by different dosing units. Each different dosing unit is provided with an independent valve and a flow meter. The controller controls the nutrient content of the nutrient solution by controlling the valve and monitoring the flow meter.

And the controller is used for controlling the nutrient substance feeding module to feed nutrient substances into the culture solution according to the data acquired by the culture solution state sensor group and configuration parameters so as to enable the culture solution state to meet the configuration parameters. The configuration parameters refer to control target values of various parameters set according to the selection of a user, and the parameters comprise the content of various nutrient components, the PH value, the temperature, the illumination and the like. As shown in fig. 3, the controller controls each component to perform an action (such as feeding nutrients, heating, supplementing light, etc.) according to the control target values of the parameters and the data collected by the sensors, so as to achieve that the actual numerical positions of the parameters are close to the target control values. In the embodiment, the chemical state (including the state of nutrient components and the pH value) of the culture solution is determined mainly according to the parameters collected by the culture solution state sensor group, then the nutrient components with the content lower than the configuration parameters are supplemented through the nutrient feeding module, and acid and alkali substances are fed to adjust the pH value.

According to the technical scheme, the planting machine can automatically adjust the content of nutrient elements in the culture solution according to the configuration parameters of a user, does not need the user to manually allocate or replace the nutrient solution, saves the time and energy of the user, and achieves a better planting effect.

The client can be an APP (application), a PC (personal computer) client, and the communication module can be a WIFI (wireless fidelity) module, a 4G module and the like. Taking the client as an APP as an example, when the user configures parameters, the user can set each nutrient component, PH value, and the like individually, and in this case, the user instruction sent by the APP to the controller includes these pieces of information. In a subsection embodiment, a client displays planting types and recommended growth schemes for a user, after the user selects the growth schemes, the APP sends related scheme numbers to the controller, and the controller searches related configuration parameters from a local server or a server according to the scheme numbers.

Therefore, the need of plant growth can be met by arranging the light supplement lamp. The user customer sets for irradiant target value, and the planter utilizes the light filling lamp to compensate to the not enough illuminance according to the condition of illumination sensor sampling for the illumination condition of plant is invariable relatively.

In some embodiments, the controller determines a planned illumination amount of each period according to the configuration parameters, and controls the light supplement lamp to supplement light at a preset time period according to actual illumination amount sensed by the illumination sensor.

It can be understood that in order to avoid the long-term on/off of the light supplement lamp, a mode of light supplement in a concentrated period can be adopted, for example, a planned illumination amount (preset light intensity x time) is set, the controller integrates the actual illumination amount according to the detection data of the illumination sensor, then the luminance and the light supplement time required by the light supplement lamp are calculated, and then the plant is subjected to concentrated light supplement at night. The mode can accurately realize the control of the illumination quantity, and meanwhile, the damage or the service life shortening of the light supplement lamp caused by frequently adjusting the light supplement lamp can be avoided.
