FIG. 2 is a flowchart illustrating an agricultural facility control method according to a preferred embodiment of the present invention. Referring to FIG. 2, step S represents a step in which the main microcontroller 108 in FIG. FIG.

The operation of the agricultural facility control method according to the present invention will be described in detail as follows.

First, a CCTV device 104 installed in an agricultural facility takes a picture of the vicinity of an agricultural facility or crops to generate a security and surveillance image or a crop image, and transmits it to the remote terminal 300 through the Internet 200 . That is, the surveillance CCTV apparatus generates the surveillance image, and the crop capturing CCTV apparatus generates the crop image. The generated image may be transmitted to the remote terminal 400 as a personal computer via the Internet 200, the network interface device 105 and the main microcontroller 108 as needed.

Therefore, the user can easily manage the agricultural facility remotely without managing the agricultural facility in the place where the agricultural facility is installed.

Here, the remote terminal 400 stores the received monitoring image and the crop image in the storage device so that the user can check the image later.

The user can remotely transmit a control command for controlling the agricultural facility through the remote terminal 300 or 400. The remote control command data thus transmitted is transmitted to the main microcontroller 100 in the agricultural facility controller 100 through the network 108).

In step S101, when the main microcontroller 108 has generated a network connection, it moves to step S102 and identifies the connection target. That is, whether the connection target is a remote terminal or another agricultural facility controller is discriminated. Thereafter, the flow proceeds to step S103 to receive data transmitted from the connection target.

In step S104, the received data is analyzed to confirm whether it is relay data. Here, the relay data and its own data are inserted in a part of the data transmission format so as to be able to distinguish them, and can be easily identified.

If the received data is the relay data as a result of analyzing the received data, the flow proceeds to step S105 and the received data is transmitted to the remote terminal or another agricultural facility controller. Here, in the case of data relay, since the destination information to receive the data is included, the relay position can be easily recognized.

On the other hand, when the received data is not the relay data but the data transmitted to the host, that is, the control command is received from the remote terminal or the control command is relayed from the other agricultural facility controller, .

In step S107, it is confirmed whether the extracted agricultural facility control data is house cover control data. Here, by including the identification information capable of distinguishing the control object for each agricultural facility control data, it is possible to easily identify the control object.

If it is determined that the control object is not the house cover, the control proceeds to step S108 to drive the agricultural facility drive unit 117 through the agricultural facility control unit 120 to operate the agricultural facility except for the house cover do. For example, the ceiling curtain is opened or closed, the pump is operated, and the shower motor is operated to automatically spray water on the crop.

If it is the house cover control data or the agricultural facility control data including the house cover control data as a result of the checking in step S107, the process goes to step S109 to generate the house cover control data.

Here, the house cover control data generation is to operate the system stably without overloading the system and the motor through electronic control.

That is, when the control target is the house cover, control data for opening or closing the house cover is generated and transmitted to the motor driver 109. The motor driver 109 operates the switch 110 according to the control data to be transmitted The house cover is opened or closed. In this case, since it is a mechanical control method using a relay that relays the motor to change the direction of rotation of the motor instantaneously during the normal / reverse conversion of the opening / closing motor, the system and the motor are unreasonably affected, and system malfunction and motor malfunction frequently occur. That is, the method of simultaneously driving a plurality of switch motors through a single relay has made it difficult for the system and the motor. Here, in the event of a system failure or motor damage, it is impossible to control agricultural facilities, which can cause damage to crops. In particular, the conventional mechanical control method has a drawback in that it requires a lot of devices such as a magnet switch, a fuse, and a toggle switch, and the device configuration is complicated and maintenance is difficult due to difficulty in repairing a fault.

In order to solve the problems of the conventional mechanical control system, the present invention has designed an existing mechanical control system as an electronic control system. Here, the electronic control method is to precisely control the motor by pulse width modulation (PWM) such as stop, delay, forward rotation, reverse rotation, low speed, high speed, etc., Thereby preventing system malfunction and motor damage.

For example, it is checked whether the house cover is opened or closed by extracting the house cover control state information. If the house cover is opened, control data is generated in the order of stop, delay, motor forward rotation, low speed, The control data is generated in the order of stop, delay, motor reverse rotation, low speed, and high speed.

In step S110, the house cover is controlled by controlling the switch 110 based on the house cover control data thus generated.

By controlling the switch motor through electronic control as described above, it is possible to prevent a system malfunction and a motor damage, so that maintenance is hardly required, thereby reducing maintenance time and cost. In addition, although the mechanical control system can not control the opening and closing amount of the house cover, the electronic control system according to the present invention can be finely controlled, so that the opening and closing amount of the house cover can be controlled.

 That is, the house cover opening / closing motor is controlled electronically through the motor driver, and the opening / closing amount of the house cover is controlled through the pulse width modulation control of the motor driver.

On the other hand, if it is determined in step S101 that no network connection has occurred, the process proceeds to step S111 where environment information such as temperature, humidity, carbon dioxide concentration, and the like is acquired through the sensor unit 101 installed in the agricultural facility. The environmental information thus obtained is processed by the separately installed sub micro controller 102 and transmitted to the remote terminal 400 and the main micro controller 108 through the network.

Particularly, it is possible to reduce the load sharing of the main microcontroller 108 by separately implementing the microcontroller in each sensor or the sensing device, and causing each microcontroller and the main microcontroller 108 to organically link through the network So that the main microcontroller 108 can quickly and efficiently control agricultural facilities.

In addition, the remote terminal 400 receives the acquired environment information and human body detection information through the data communication with the sub micro controller 102 via the network, and stores and manages the environment information and the human body detection information. In particular, the environmental information is statistically processed through classification codes such as hourly, daily, monthly, yearly, and seasonal, and then stored, thereby making it convenient for the user to use the environmental information later.

In step S112, the main microcontroller 108 analyzes environmental information obtained through interlocking with the sub-microcontroller 102, and determines whether the agricultural facility is controlled. That is, it compares the acquired environmental information with a reference value stored in advance in the internal memory for automatic control, and determines whether or not to control the agricultural facility. For example, the main microcontroller 108 automatically opens and closes the ceiling curtain and / or the house cover when the acquired temperature is higher or lower than the reference value, or automatically activates or deactivates the shower when the humidity is higher or lower than the reference value To control agricultural facilities.

If it is determined that the agricultural facility is controlled through this process, the agricultural facility control data is generated in step S114, and the generated control data is transmitted to the remote terminal or another agricultural facility controller in step S115.

After generating the agricultural facility control data, the process goes to step S107 and performs the following operations as described above.

That is, when the agricultural facility is controlled except the house cover, the main relay 120 of the agricultural facility control unit 120 operates to generate an agricultural facility driving signal, and the semiconductor switch 113 is driven And generates an agricultural facility driving signal. Then, the electromagnetic contactor 114 operates according to the generated agricultural facility driving signal to drive the agricultural facility driving device 114 connected thereto to open or close the ceiling curtain, to drive or stop the pump, to drive the shower Or off. The LED lighting unit 115 and the ventilation fan 116 are connected to the semiconductor switch 113 so as to drive the lighting apparatus or control the operation of the ventilation fan as required. For example, when the interior of the house is dark, the lighting apparatus is driven to illuminate the lighting or to supply a necessary heat source. When the concentration of the carbon dioxide or the like is high, the ventilation fan or the like is operated, The outside air is introduced, and the ventilation is performed.

The limit switch 118 confirms a predetermined control range when driving the agricultural facility and transmits the control signal to the electromagnetic contactor 114. The electromagnetic contactor 114 is connected to the ceiling curtain motor 110 in accordance with the limit signal detected through the limit switch 118, Thereby controlling the driving of the motor 117a. That is, the limit switch 118 is provided at a position where it is desired to open and close. When the limit switch 118 is in the open position, the limit switch 118 senses the contact through the contact and transmits the position information to the electromagnetic contactor 114. The electromagnetic contactor 114 controls the driving of the motor in accordance with the position information. Further, the user can select the driving direction of the motor by using the forward / reverse switch 119. [ For example, assuming that the ceiling curtain is opened in the forward direction of the motor and the ceiling curtain is closed in the reverse direction of the motor, if the ceiling curtain is to be opened, the forward / reverse switch 119 is set to the forward position, and the ceiling curtain is closed The normal / reverse changeover switch 119 is placed in the reverse position. The electromagnetic contactor 114 drives the motor in the forward or reverse direction according to the operation of the normal / reverse changeover switch 119.

When the control target is the house cover, control data for opening or closing the house cover is generated and transmitted to the motor driver 109. The motor driver 109 operates the switch 110 according to the control data to be transmitted , The house cover is opened or closed.

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.

The present invention is applied to technology for controlling agricultural facilities using IT technology. Particularly, it is applied to the technology for automatically acquiring environmental information and controlling the agricultural facility through the network based on this information.
