However, such conventional plant cultivation management systems using sunlight and the like have not considered the problem of optimizing the power supply to supply stable moisture in the cultivation complex. Therefore, it is necessary to install more than necessary solar panels and waste of electric power was high. Particularly, in order to compensate the initial starting current in the motor that operates the sprinkler for water supply, the power consumption is inefficient because the supply power must be secured larger than the average usage amount.

Therefore, it is possible to control the water supply, ventilation, heating, and lighting of the flower complex automatically, but also to improve the power supply efficiency by optimally supplying the power from the sunlight or another power source. There is a need to develop.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a schematic block diagram illustrating functions of a flowerpot management system according to an embodiment of the present invention. Referring to FIG.

As shown in FIG. 1, the flower complex management system of the present invention includes an energy generating unit 100, a battery unit 200, a motor unit 300, a sensor unit 400, and a control unit 500.

The energy generation unit 100 converts the renewable energy into an electric signal and outputs the electric signal. In the present embodiment, solar light is described as an example. 2, the energy generating unit 100 of the present embodiment includes a PV panel (photovoltaic panel) 110, a PV voltage and current measurement circuit 120, and a PV converter 130. However, the energy generating unit 100 is not limited to solar power generation, and an energy generating unit may be implemented using hydraulic power or wind power.

The PV panel 110 converts sunlight to DC voltage, and is made of a silicon solar cell or a compound solar cell. The PV voltage / current measurement circuit 120 measures the voltage and current output from the PV panel 110. The PV converter 130 boosts the voltage input from the PV panel and applies the boosted voltage to the DC link LINK.

3, the battery unit 200 includes a battery 210, a battery voltage / current measuring circuit 220, a charge / discharge converter 230, a battery temperature sensor 240 And a battery fan 250.

The battery 210 is for storing electric power, and can be configured by connecting a plurality of battery cells in series. The charge / discharge converter 230 functions to convert a voltage charged and discharged in the battery 210. The charge / discharge converter 230 reduces the input voltage and supplies the reduced voltage to the battery 210. When the battery is charged, the charge / discharge converter 230 boosts the output voltage and applies the boosted voltage to the DC link.

The battery voltage / current measuring circuit 220 measures the voltage and current values output from the battery 210, and the battery temperature sensor 240 measures the temperature of the battery 210. Based on the measured voltage and current values and the temperature, the controller 500 determines the characteristics of the battery 210. The main characteristic to be judged is the state of charge, and the impedance, the use temperature and the charge voltage can be additionally judged.

For example, it is possible to determine the state of charge (SOC) by accumulating the charge / discharge current flowing in the battery 210. [ As another method, the voltage of the battery 210 is measured, an open loop voltage (OCV) of a no-load state is estimated from the measured voltage, and an SOC corresponding to the estimated open- And may determine the state of charge (SOC) by mapping.

The battery unit 200 further includes a battery fan 250 for lowering the temperature of the battery 210. By lowering the temperature of the battery 210 by the fan 250, the efficiency of the battery 210 can be further improved.

The floating charge voltage of the battery 210 may be adjusted according to the temperature of the battery 210 measured by the battery temperature sensor 240. In this case, That is, the charging voltage of the battery 210 is adjusted according to the difference between the preset optimal battery temperature value and the measured battery temperature value. The optimal battery temperature may be set according to the intrinsic characteristics of the battery 210.

For example, if the optimum battery temperature is set at 25 ° C, the floating charge voltage can be adjusted by the value of [(measured temperature value - 25 ° C) x -3 mV].

In the present invention, by employing the battery unit 200 as described above, not only energy saving is very advantageous, but also an uninterruptible system can be realized.

Next, the sensor unit 300 measures environmental conditions in the flower park. Concretely, water, ventilation, heating and lighting conditions in the flower park are measured, and it can be constituted by a general moisture sensor, a ventilation sensor, a temperature sensor, an illumination sensor and the like. Here, the moisture sensor will be mainly described.

Next, the motor unit 400 may be constructed of a motor that operates the sprinkler according to the measured value of the sensor unit 300 to adjust the moisture in the flower pot. It is desirable to use a BLDC motor that is easy to miniaturize and has good battery efficiency.

The motor unit 400 receives power through the DC link to which the generated power of the energy generating unit 100 and the charging power of the battery unit 200 are applied and drives each motor according to a command of the controller 500. [

The control unit 500 includes a microcontroller unit (MCU) and includes an energy generating unit 100, a battery unit 200, a sensor unit 300, a motor unit 400, .

Specifically, the control unit 500 controls the motor unit (not shown) based on the measured moisture level from the sensor unit 300, the power state generated from the energy generating unit 100, and the charged state (SOC) of the battery unit 200 400 is driven by the motor.

Generally, in the case of a DC motor, it shows the starting current characteristic as shown in Fig. That is, a large amount of current is consumed only at the time of starting, and then a constant current is consumed. Specifically, 300% of the amount of the steady-state current is required to be secured at the time of starting the initial motor, so that system output and power generation are possible, resulting in low efficiency and economical efficiency. Therefore, there is a need to supplement the starting current portion by using battery power.

In consideration of this, in the present invention, the operation of the motor and the charging operation of the battery are controlled as shown in the flowchart of FIG. 5, thereby improving the power usage efficiency.

As shown in Fig. 5, the control unit 500 receives the moisture state in the flower shop from the sensor unit 300 and determines whether the motor is started or not.

That is, if the water state is in a good state or more than the reference value, the control unit 500 continues the battery charging operation without starting the motor. On the other hand, when the water state is in a bad state below the reference value, the control unit 500 determines that the sprinkler should be operated by starting the motor (step 100).

If it is determined that the motor should be started, the control unit 500 determines whether the power required for starting the motor is ready based on the sum of the generated power of the energy generation unit 100 and the charging power of the battery unit 200 (Step 200).

That is, when the sum of the generated power of the energy generation unit 100 and the charging power of the battery unit 200 is equal to or less than the amount of power required for starting the motor, it is determined that the power required for starting the motor is not ready. The battery 210 of the battery pack 200 is continuously charged. On the other hand, when the sum of the generated power of the energy generating unit 100 and the charging power of the battery unit 200 is equal to or greater than the power required for starting the motor, the power required for starting the motor is determined to be ready and the motor is driven. At this time, when the electric power required for starting the motor is not ready, another electric power source such as another generator may be additionally used to drive the motor.

The generated power of the energy generating unit 100 may be calculated from the voltage and current values of the PV voltage and current measuring circuit 120 and the charging power of the battery unit 200 may be calculated from the voltage and current of the battery voltage / Value. ≪ / RTI > The amount of power required for starting the motor is set in advance based on the intrinsic characteristics of the motor.

After the motor is driven as described above, the sensor unit 300 determines whether the motor is stopped based on the measured value (step 300).

That is, when the water state is restored to a good state or more than the reference value due to the operation of the sprinkler, the control unit 500 determines that the motor should be stopped.

If it is determined that the motor should be stopped, the motor is stopped and the battery 210 is charged. The battery 210 is fully charged and maintained in that state.

As described above, by controlling the starting of the motor and the charging operation of the battery, the charging power of the battery can be used in accordance with the starting current characteristic of the DC motor.

The present invention is not limited to the embodiments described above, but a plurality of sensor units 310, 320, 330, 340, 350, and 360 may be used as the sensor unit 300, 620, 630, and 640, which can drive a plurality of sprinklers, can be installed to form a system.

FIG. 6 shows a schematic configuration of a flower complex management system including the plurality of sensor units 310, 320, 330, 340, 350, and 360. 6, the field complex management system includes a plurality of sensor units 310, 320, 330, 340, 350 and 360, a plurality of driving units 610, 620, 630 and 640 and a control unit 500 do.

Each of the plurality of sensor units 310, 320, 330, 340, 350 and 360 has the same configuration as that of the sensor unit 300 described above, and is separately installed at various places in the flower park to measure the environmental condition within the park. The measured value (for example, moisture value) at each sensor unit is transmitted to the control unit 500, and the control unit 500 analyzes the received measurement value and controls the operation of the driving unit. For example, the control unit 500 may collectively control the plurality of the driving units 610, 620, 630, and 640 using the average value of all the measured values, So that the driving unit can be operated selectively. The selective actuation of the drive leads to the selective operation of the sprinkler, making it possible to selectively raise the humidity only in low humidity areas within the jar.

For example, when the measured moisture value received from the sensor units 610 and 620 is less than the reference value, the controller 500 controls the motor of the driving unit connected to the sprinkler to operate only the sprinkler near the position where the sensor units 610 and 620 are installed Start. The battery charging operation is carried out without activating the motor for the driving unit which does not operate the sprinkler. By individually controlling the driving units as described above, it is possible to selectively manage the areas within the flower complex.

Each of the driving units may include only the motor unit 400 shown in FIG. 1, but may further include the energy generating unit 100 and the battery unit 200.

When each of the driving units is composed of only the motor unit 400, electric power is supplied from a commercial power supply or the like to the driving unit by wire or wirelessly. On the other hand, when the energy generating unit 100 or the battery unit 200 is included in addition to the motor unit 400 in each driving unit, it is not necessary to supply wired or wireless power, To produce electricity.

The plurality of sensor units 310, 320, 330, 340, 350, and 360 and the plurality of driving units 610, 620, 630, and 640 may be installed in pairs in the same number. However, none. 6, a larger number of sensor units 310, 320, 330, 340, 350 and 360 than the driving units 610, 620, 630 and 640 are provided, and the positions, , It is possible to select a driving unit to be operated by the control unit 500 based on the position of each driving unit.

Meanwhile, the flowerpot management system according to the embodiment of the present invention can perform communication between each constituent unit through a wireless network. The wireless communication may employ a communication method such as Wi-Fi, WiBro, Bluetooth, ZiBee, RF modem, infrared, and the like.

The controller 500, the plurality of sensors 310, 320, 330, 340, 350, and 360, and the drivers 610, 620, 630, and 640 include wireless communication modules, The part and each driving part include a unique identifier (ID). If the sensor unit and the driving unit are provided in pairs at the same position, only one wireless communication module and one unique identifier may be provided for the pair of sensor units and the driving unit.

On the other hand, in the flower garden management system of the present invention, since continuous measurement is not necessarily required from each sensor unit and only periodic or intermittent measurement is sufficient, it is preferable to perform wireless communication only when the measurement is performed. That is, by setting the control unit 500 and each sensor unit to transmit and receive data at a predetermined time interval, energy consumption for communication can be reduced and energy can be saved.

In addition, since the flower complex management system of the present invention has a wireless network, the control unit 500 can be controlled remotely through the wireless network. That is, it is possible to monitor and control the management system by using a mobile device (not shown) provided with an application capable of communicating with the control unit 500 through the wireless network.

Specifically, the control unit 500 controls the amount of water, the ventilation, the heating and lighting state in the flower pot measured from the sensor unit 300, the power state generated from the energy generating unit 100, the charging state of the battery unit 200 To a mobile device such as a smart phone or a PDA (Personal Digital Assistant). The mobile device is received in the moisture state, the power state, and the charging state through the application, and transmits a command for the operation of each driver to the controller 500 based on the received data. Of course, a command for the operation of each driver is executed by command input of the user of the mobile device. The control unit 500 receives a command for the operation of the driving unit through the wireless communication module and controls the operation of the driving unit accordingly.

In addition, the flower garden management system of the present invention can systematically manage data in cooperation with a separate server system. That is, it is possible that the server system receives various information related to the flower garden management from the control unit or the mobile device through the wireless network, collects and analyzes the information, and more efficiently controls the flower garden based on the analyzed data.
