The present invention relates to a waterer for pollen management, and more specifically, to a waterer for automatically supplying water to potted plants.

In recent years, the number of dwellings in multi-unit dwellings such as apartments has increased, and since multi-unit dwellings do not have yards, the number of households that grow plants by placing pots in the house is increasing.

Unlike plants grown in the open air, plants grown in houses do not receive moisture due to rainfall, so it is necessary to observe the condition of the soil and the condition of the plant in the pot to ensure that there is no shortage of moisture. However, when it is difficult to manage plants due to long-term travel or other circumstances, moisture necessary for plant growth is insufficient, which often causes the plant to dry out and hinder growth.

The environmental measurement integrated sensor board 310 attaches and manages at least one of a temperature sensor, a humidity sensor, a carbon dioxide concentration sensor, an illuminance sensor, and a camera in a modular form.

That is, when a plurality of temperature sensors, humidity sensors, carbon dioxide concentration sensors, illuminance sensors, and cameras are individually provided, a communication module must be attached to each sensor, and integrated management is difficult.

Therefore, the environmental measurement integrated sensor board 310 is configured to include a common control circuit such as a control circuit and a communication module, and to combine a temperature sensor, a humidity sensor, a carbon dioxide concentration sensor, an illuminance sensor, and a camera in a module form.

4 is a configuration diagram of an integrated environmental measurement sensor board according to an embodiment of the present invention.

Referring to FIG. 4 , the environmental measurement integrated sensor board 310 according to the present embodiment can measure external temperature values and internal temperature values, respectively, and a battery life management function is added.

Here, the external temperature value may be defined as the temperature around the battery, and the internal temperature value may be defined as the temperature of an internal circuit that performs a battery life management function. In FIG. 4 , only the temperature sensor for measuring the internal temperature value is shown, and the sensor for measuring the external temperature value is omitted.

Referring to FIG. 4 , the environmental measurement integrated sensor board 310 includes a temperature sensor 35, a current measuring unit 31, a voltage measuring unit 32, a power amount measuring unit 33, and a battery monitoring unit 34. It is composed by

When the temperature sensor 35 is provided, a process of correcting the measured data according to the detected temperature value - the data of the current measuring unit 31, the voltage measuring unit 32, and the energy measuring unit 33 - respectively proceeds. do.

As an example of the temperature sensor 35, the temperature sensor 35 may include a voltage generator and a temperature code output unit.

The voltage generator includes a first temperature element having a predetermined first resistance value and a second temperature element having a second resistance value, and the voltage level is changed according to the temperature change by the first and second temperature elements. generate a corresponding voltage. In addition, the voltage generator generates a reference voltage that maintains a constant voltage level according to the driving voltage level even when a temperature change occurs.

In addition, the temperature code output unit generates a plurality of temperature codes by comparing the reference voltage and the temperature corresponding voltage. That is, the temperature code includes temperature information.

As another example of the temperature sensor 35, the temperature sensor 35 may include a reference voltage output unit, a digital-analog conversion unit, a comparator, a digital signal generator, a storage unit, and a data output unit. can

The reference voltage output unit generates a reference voltage that changes in response to temperature.

The digital-to-analog conversion unit converts an N (integer greater than 1) bit digital signal into an analog sensing voltage and outputs it.

The comparator compares the reference voltage with the analog sensing voltage and outputs a comparison result.

The digital signal generator varies the digital signal according to the comparison result of the comparator, and the storage unit stores the output signal of the digital signal generator at the first temperature.

The data output unit outputs data corresponding to the second temperature according to the output signal of the digital signal generator and the output signal of the first storage unit at the second temperature.

The battery 350 of this embodiment is defined as a means of storing solar energy. That is, the battery 350 stores energy supplied from the solar panel.

The battery 350 supplies power to at least one load device having constant power consumption in a discharge mode.

Here, the battery 350 may be defined as a rechargeable lead-acid battery or a lithium ion battery, and the load device may be defined as an environmental control device such as a pump.

The current measurement unit 31 measures the current between the battery 350 and the load device, and the voltage measurement unit 32 measures the voltage of the battery 350 . In addition, the power measurement unit 33 measures the amount of power consumed by the battery 350 .

The battery monitoring unit 34 receives the data measured by the current measurement unit 31, the voltage measurement unit 32, and the energy measurement unit 33 in real time, monitors and stores the measured data based on time, and measures the measured data. control to display the data on the display device.

First of all, the battery monitoring unit 34 controls to output a warning from the time point when the amount of power consumption (Wh) for one day exceeds the preset first reference amount of power consumption (Wh).

Next, the battery monitoring unit 34 controls the discharge of the battery from the point of time exceeding the second reference power consumption (Wh) greater than the first reference power consumption (Wh), or determines the additional power amount in consideration of the reserve power amount. can be controlled to give

In addition, the battery monitoring unit 34 grasps the reference performance data STD_DATA of the newly installed battery 350 up to a predetermined reference period STD to determine a performance index. Here, the predetermined reference period (STD) may be set as the most suitable period of about one week from the time when a new battery is installed and used.

That is, the battery monitoring unit 34 detects the change value ΔV of the battery voltage according to the amount of power consumed (Wh) hourly under a constant discharge condition generated by the load device and stores it as the reference performance data STD_DATA.

At this time, it is assumed that the power consumption (W) of the load device is constant. That is, in general, a system using a battery is designed considering the power consumption (W) of the load device. In this embodiment, it is assumed that the power consumption (W) consumed by the load device is always constant in a normal state, and the deviation is defined as not exceeding 15% even if it occurs. In addition, it is most preferable to measure the change in battery voltage right before the end of discharge voltage.

The battery monitoring unit 34 determines the change value (ΔV) of the battery voltage according to the amount of power consumption (Wh) by time even after the new battery is installed and the performance index is identified, that is, even after the reference period (STD), and the reference performance data (STD_DATA) ) and determine the degree of aging of the battery based on the difference in the rate of change.

That is, when the battery monitoring unit 34 grasps the reference performance data STD_DATA of the newly installed battery 350 up to a predetermined reference period STD,

Under the constant discharge conditions generated by the load device, the battery voltage change value (ΔV) according to the amount of power consumption (Wh) is identified over time, and the change value (ΔV) of the battery voltage against the amount of power consumption (Wh) and the battery voltage The power usage time versus the change value (ΔV) is calculated and stored as the reference performance data (STD_DATA). For reference, the battery voltage change value (ΔV) versus power consumption (Wh) may be calculated and used as the reference performance data (STD_DATA) instead of the battery voltage change value (ΔV) versus the power consumption (Wh).

At this time, even after the reference period (STD), the battery monitoring unit 34 calculates the change value (ΔV) of the battery voltage versus the amount of power consumed (Wh) and the power usage time versus the change value (ΔV) of the battery voltage to calculate the reference performance data ( STD_DATA) and determine the degree of aging of the battery based on the difference in the rate of change. At this time, it is desirable to grasp the degree of aging for a period of about 7 to 10 days.

The battery monitoring unit 34 calculates the change in battery voltage (ΔV) against the amount of power consumed (Wh) after the reference period (STD) and the rate of change in power usage time versus the change in battery voltage (ΔV) as reference performance data (STD_DATA). ), it is determined that the primary replacement is required due to aging of the battery when all of them have 50% or less performance in preparation for the battery.

Compared to the standard performance data (STD_DATA), all having 50% or less performance means that the battery 350 is aging and has less than 50% performance compared to the standard performance data (STD_DATA) identified for a predetermined reference period (one week). Means that. Therefore, the criterion for determining the primary replacement required state can be set as the criterion for performance degradation of 60% or less, and in this embodiment, the criterion for 50% has been described.

Meanwhile, the battery monitoring unit 34 may additionally calculate a rate of change of discharge current (mAh) versus power use time and a rate of change of power consumption (Wh) versus power use time. - Calculate the rate of change based on the reference performance data (STD_DATA) for a predetermined reference period (STD) - At this time, it is desirable to grasp the degree of deterioration during a period of about 7 to 10 days.

That is, when the battery monitoring unit 34 determines that the primary replacement is required, when the rate of change of the amount of power consumed (Wh) versus the time of power use exceeds twice the rate of change of the amount of discharge current (mAh) compared to the time of power use. , It is determined that the secondary replacement is necessary according to the deterioration of the battery 350.

In other words, if the rate of change in power consumption (Wh) versus power use time exceeds twice the rate of change in discharge current (mAh) versus power use time, it means that power consumption (Wh) compared to power use time drops sharply. It can, which means that it doesn't actually do much work, so you can estimate the aging of the battery.

That is, the battery monitoring unit 34 controls a warning to be output even in a state in which a primary replacement requirement occurs, and when a secondary replacement requirement additionally occurs, a warning indicating that the aging state of the battery is very serious may be output.

As described above, by setting the amount of power consumption to be used per day, when excessive power consumption occurs, it is cut off or warned. In other words, since the battery capacity is designed in consideration of the power consumption used, over-discharge of the battery occurs when over-consumption occurs and the life span can be shortened.

In addition, the battery monitoring unit 34 of the environmental measurement integrated sensor board 310 measures daily power consumption. That is, it is possible to monitor the power consumption by identifying the amount of power consumption with the power consumed by the battery and displaying the accumulated amount of use.

In addition, the battery monitoring unit 34 constantly measures/monitors the charging/discharging voltage and current of the battery, and monitors the variation of the battery voltage according to the amount of power consumed when a load is used.

In addition, the battery monitoring unit 34 measures the battery discharge time (measures the power use time). That is, by measuring the change in the discharge time of the battery according to the power consumption, the amount of change when the battery is used for a long time can be compared. That is, the discharge time of the initially installed battery and the discharge time of the battery used for a long time under the same discharge conditions are compared to measure the amount of change compared to the initial required time.

In addition, the battery monitoring unit 34 compares the discharge voltage and time of the battery according to the power consumption, and sets the amount of power that can be consumed per day according to the design.

The operation procedure of the above-described integrated environmental measurement sensor board 310 can be described in order as follows.

1st: Voltage fluctuation range compared to power consumption

1) Standard: Set the standard value with the average data of the initial period after installation (e.g. 7 days)

2) Measure the value of change according to the range of change after completing the standard setting

- Comparative calculation of the amount of change in voltage variation according to the amount of power consumption to the reference value

- Comparison based on voltage range up to battery low voltage setting

- If the voltage change range is less than 50% of the power consumption, the battery life is expected to be shortened because the battery discharge is large because the voltage change range is larger than the same power consumption.

2nd: power consumption time (discharge time) - voltage fluctuation range comparison

1) Standard: Set the standard value with the average data of the initial period after installation (e.g. 7 days)

2) Power consumption time

- Comparison of power consumption time during 1V discharge, comparison of battery voltage fluctuation range and power consumption time compared to standard time, and display

- If the voltage change range is less than 50% compared to the standard, the battery life is expected to be shortened because the voltage change range is larger than the power usage time, so it is discharged in a short time.

3rd: Comparing the voltage fluctuation width and time_voltage fluctuation width against the amount of power consumption, and when the same occurs at 50% or less

- Battery life is expected to be shortened by 50% or less compared to the standard, so it warns that you can analyze the battery replacement time or factors that can affect life shortening.

4th: Discharge time warning due to abnormal current or overcurrent use

1) Standard: Set the standard value with the average data of the initial period after installation (e.g. 7 days)

2) Compare time and current to the reference value on a time basis, and if greater than 1, warn about the effect of shortening the usage time due to the use of overcurrent (check items or load usage check required)

5th: Warning by comparing time for current and current_time_wattage

<Change rate of discharge current (mAh) versus power use time and change rate of power consumption (Wh) versus power use time>

1) Standard: Set the standard value with the average data of the initial period after installation (e.g. 7 days)

2) When a difference of more than two times occurs after comparing the above calculation values (when the change rate of power consumption (Wh) versus power use time exceeds twice the change rate of discharge current (mAh) versus power use time) It is necessary to check for excessive discharge, battery replacement, maintenance, and repair.

Finally, when the 3rd and 5th results are warned at the same time, the battery life is reduced to 50% or less, so it is necessary to check the replacement timing.

Under a constant discharge condition, the change value (ΔV) of the battery voltage according to the amount of power consumption (Wh) is identified over time, and the degree of deterioration of the battery can be determined based on the difference in the change rate.

Therefore, the degree of deterioration of the battery can be determined by determining the current between the battery and the load device, the voltage of the battery, and the amount of power consumed by the battery over time without requiring a separate device such as an electrolyte meter.

Meanwhile, a plurality of cameras of the environmental measurement integrated sensor board 310 may be provided. That is, after taking a plant image using a plurality of cameras (visible ray region imaging camera, near-infrared ray region imaging camera, long-wave infrared region imaging camera), the distance of the plant is measured, and the height of the plant and the total surface area of the leaf are measured. It is possible to predict the growth status and nutrient deficiency status by taking into account.

Here, the total surface area of the leaves of the plant unit is defined by a method of estimating the actual surface area by detecting the outer contours of all leaves (the outer contours detected on the photographed screen). By substituting the height of the plant here, the current growth state can be predicted.

In particular, it can be used to detect the outer contours of all leaves using an algorithm based on the frangi filter. That is, when using the frangi filter, there is an advantage in that the edges of continuous shapes are more clearly distinguished. Therefore, the shape of the leaf can be detected more quickly and accurately.

In addition, it is possible to automatically analyze plant morphology, plant stress (NDVI: Normalized Difference Vegetation Index), and nutrient deficiency based on the photographed images.

In addition, it is classified according to the photographing wavelength, and nutrient deficiency is automatically analyzed after capturing plant images using a plurality of cameras (visible ray region imaging camera, near infrared region imaging camera, and long-wave infrared region imaging camera).

For reference, if a time lapse camera is added that can photograph plants at intervals selected from 0.3 seconds to 60 seconds, the environmental measurement integrated sensor board analyzes the time lapse images of a plurality of plants.

That is, the environmental measurement integrated sensor board analyzes each correlation between the growth rate of each leaf, the growth order of each leaf, the growth rate of the plant, the flowering rate of the flower, and the quality of the fruit according to the growth rate of the fruit. This can be provided as analysis data. In addition, based on the growth rate of each part of the plant in the time-lapse video, the disease symptoms of the plant can be predicted and provided as analysis data. In addition, based on the color change of the fruit of the plant in the time-lapse video, the optimal harvest time can be predicted and provided as analysis data.

Basically, the information captured by the camera of the environmental measurement integrated sensor board 310 is image-processed, analyzed, and detected by the environmental measurement integrated sensor board 310 itself, and as a result, the data is sent to the smartphone or data server 330. ) is sent to

When the processing capacity of the processor of the environmental measurement integrated sensor board 310 is limited, the captured image of the camera is transmitted to the data server 330, and the image processing, analysis, and detection processing are performed in the data server 330. It can also distribute the computational load automatically. The computational load is automatically distributed to the data server 330 so that the maximum occupancy of the processor of the integrated environmental measurement sensor board 310 is maintained at 80% or less.

Meanwhile, when the camera can capture a 360-degree circular image, the captured 360-degree circular image is transmitted to the data server 330 and image-processed. The data server 330 partially distorts the circular image to generate a flat image. Segment the circular image for resolution and partial image processing. That is, the unit of the divided circular image (circular division unit image) may be divided in consideration of resolution, arc, pixel, image distortion, and the like.

A method of generating a flat image based on a circular segmentation unit image is as follows.

First, a pixel structure of a circular division unit image may be grasped. Reference focus pixels for the circular segmentation unit image of which the pixel structure is determined may be extracted. A reference focus pixel may be a pixel that does not require expansion or contraction. The pixel structure may be divided into pixels to be reduced and pixels to be expanded based on the reference focus pixel.

A correction process per pixel may be performed to eliminate partial distortion for generating a plane division unit image. For example, reduction may be performed by determining a reduction area for an area expanded based on a reference focus pixel, and expansion may be performed through interpolation after determining an expansion area for the reduced area. A plane segmentation unit image may be extracted through additional image processing in consideration of resolution, arc, pixel, image distortion, and the like. Through this method, a plurality of circular division unit images may be generated as a plurality of planar division unit images.

That is, when a panoramic image is transmitted, the data server 330 identifies objects on the screen after generating a plurality of plane division unit images as described above, so that the probability of automatic identification is further increased.

The environmental measurement integrated sensor board 310 transmits 360-degree captured images and at the same time transmits image processing commands to be processed to the data server 330, and only the result values can be fed back.

In this way, the data server 330 feeds back the recognized object information to the environmental measurement integrated sensor board 310, and each object information includes a pre-assigned identification code for each object type and location information for each object's central area by time. includes

For example, when an object called a flower is recognized from an image on the screen, an identification code pre-assigned to the flower and time-specific location information about the location (coordinates) of the center area of the flower are transmitted.

For reference, the identification code includes an object code and an additional code. The object code is a code given to the shape of a flower, and the additional code is defined as encoding additional data information such as the type of flower, number of petals, and color. .

In addition, the data server 330 feeds back the part where the image does not change among the captured images, and the environmental measurement integrated sensor board 310 automatically removes the part where there is no change in the image, thereby providing its own storage capacity (environmental measurement integrated sensor board ( 310) may be reduced.

In addition, the data server 330 divides the image into a plurality of areas, and then feeds back information capable of changing the stored image frame for each area to the integrated environmental measurement sensor board 310 in consideration of the movement speed of the object. there is.

On the other hand, the environment measurement integrated sensor board 310 may divide a preset shooting area into a plurality of sub-areas, and then independently set sensing time, sensing objects, and sensing events for each area in advance.

As such, those skilled in the art to which the present invention pertains will be able to understand that the present invention may be embodied in other specific forms without changing its technical spirit or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not limiting.
