Description

Environmental controller equipped with supplying function of watering advice solutions}

The present invention relates to an environmental controller with the function of providing an irrigation advice solution. More specifically, the present invention analyzes weather information and soil information by linking an environmental controller to a farm using an irrigation device and a fertigation device (hereinafter referred to as a “nutrient solution device”), thereby informing the farm of the appropriate input time for farming. It is about an environmental controller with the function of providing irrigation advice solutions to help with decision-making.

Green greenhouses (hereinafter referred to as “greenhouses”) installed in rural areas are formed by shielding the vegetables, fruits, and other fruit trees to be grown from the outside with plastic. Greenhouses are mainly used when the outside temperature is low. It is desirable to maintain the temperature and humidity inside the greenhouse at a constant value.

Today, in most domestic cultivation farms, farmers (hereinafter referred to as “users”) arbitrarily control the environment inside the greenhouse. When the weather outside is cold or the inside of the greenhouse is judged to be dry, the greenhouse is used by turning on the heating device or turning on the humidifier.

In this greenhouse control method, the environment inside the greenhouse is completely dependent on the user's intuition and judgment, so the user must live near the greenhouse and manage the greenhouse from time to time. Additionally, if the user improperly manages the greenhouse, problems may occur with the growth of crops grown inside the greenhouse, or in severe cases, crop cultivation may have to be abandoned.

Conventional irrigation systems operate through a timer, which is not an appropriate irrigation supply method for crops.

In the prior art, the supply of moisture and nutrients needed by crops is achieved based on the user's experience and practice, and productivity is slowed because the supply is excessively exceeding the sufficient amount for the crops, and there is a limit to improving farm efficiency due to unreasonable supply of nutrients.

As background technology for the present invention, Registration Patent No. 10-2414190 (announcement date: June 30, 2022) “Multiple greenhouse complex environmental control system” (hereinafter referred to as “prior art”) has been disclosed. The prior art relates to a multi-greenhouse complex environment control system that can monitor the internal environment, including temperature, humidity, and carbon dioxide concentration inside the greenhouse, and at the same time automatically control various actuators within the greenhouse according to the monitoring results.

It is configured to individually drive the actuators installed in each of the plurality of greenhouses.

However, the prior art had the disadvantage of lowering the appropriateness of opening and closing by considering only temperature, wind direction, and wind speed when opening and closing the side windows of the greenhouse, and not controlling them in a complex manner, which resulted in inaccurate plant management in the greenhouse and low productivity. .

Due to the irrigation action of the irrigation pump, negative pressure is generated inside each venturi pipe connected between the irrigation pipe and the mixing tank, and the negative pressure causes the nutrient solution inside the nutrient solution tank to be smoothly sucked into the mixing tank 340.

Figure 7 is a flowchart of a nutrient solution supply method according to an embodiment of the present invention.

The nutrient solution supply method of the environmental controller of the present invention includes the step of receiving setting information from the user (S310); Selecting one basic schedule from a plurality of basic schedules (S320); Creating a nutrient solution supply schedule by adjusting the selected basic schedule (S 330); A step of determining whether the nutrient solution supply cycle has arrived (S340); If the nutrient solution supply cycle arrives, checking the nutrient solution concentration or supply amount (S350); It is characterized by comprising a step of controlling the valve to mix the nutrient solution and raw water (S360) and a step of forming and supplying a nutrient solution having a corresponding concentration or supply amount at the time of supplying the nutrient solution (S370).

The nutrient solution supply method of the nutrient solution device 300 shown in FIG. 6 will be described as follows.

First, the setting information acquisition unit 350 receives information about the cultivation type from the user, and also receives setting information including the target concentration, the date on which the nutrient solution of the target concentration is supplied, the start date and end date, and the target concentration duration, etc. from the user. Receive (S310). In addition, the setting information acquisition unit 350 may receive setting information including the target liquid amount, the date on which the target liquid quantity is supplied, the start and end date, and the duration of the target liquid quantity, etc., from the operator. Then, the schedule generator 370 selects one of the plurality of basic schedules from the basic schedule storage unit 360 based on the worker's cultivation type (S320). For example, when the user selects fruit set induction as the cultivation type, the schedule generator 370 may select a basic schedule from the basic schedule storage unit 360.

The schedule generator 370 generates a nutrient solution supply schedule based on the selected basic schedule and the setting information entered by the user (S330). That is, the schedule generator 370 changes the default start date and default end date recorded in the selected basic schedule to the start date and end date included in the setting information, and sets the default target concentration duration and default target recorded in the basic schedule. A nutrient solution supply schedule is created by changing each of the default dates on which the concentration and target concentration are supplied to the target concentration duration, target concentration, and date on which the target concentration is reached included in the setting information. Meanwhile, if information related to the amount of liquid is recorded in the setting information, the schedule generator 370 sets the default target amount of liquid recorded in the basic schedule, the default target amount of liquid, and the default date on which the amount of target liquid is supplied to the target included in the setting information. A nutrient solution supply schedule is created by changing the duration of the feeding amount, the target feeding amount, and the date on which the target feeding amount is reached.

Next, the nutrient solution supply unit 380 determines whether the nutrient solution supply cycle has arrived based on the generated nutrient solution supply schedule (S340). Next, when the nutrient solution supply cycle arrives, the nutrient solution supply unit 380 checks the concentration or amount of nutrient solution to be supplied in the current cycle based on the nutrient solution supply schedule generated by the schedule generator 370 (S350).

The nutrient solution supply unit 380 of the nutrient solution device 300 controls the raw water valve 320 and the nutrient solution valve 330 so that a nutrient solution matching the confirmed concentration or supply amount is formed in the mixing tank 340 shown in FIG. 5, The raw water and the nutrient solution concentrate are mixed (S311). Next, when the nutrient solution is formed in the mixing tank 340, the nutrient solution supply unit 380 supplies the nutrient solution (S313). At this time, the nutrient solution supply unit 380 supplies the nutrient solution to the designated greenhouse by opening the nutrient solution valve 330. Afterwards, the nutrient solution 300 proceeds again after S340.

As described above, according to one embodiment of the present invention, the nutrient solution supply schedule is automatically set, the concentration or supply amount of the nutrient solution and the nutrient solution supply time are determined according to the set nutrient solution supply schedule, and the nutrient solution is automatically supplied, allowing the user to Not only does it save labor, but it also has the effect of growing crops more efficiently.
