Accordingly, when an emergency such as a failure occurs, the control unit 50 is notified and transmitted to the mobile phone 80 through the LoRa gateway 40 to be confirmed by the administrator.

And, the central control unit 70 that receives the information of the livestock house from the remote control monitoring unit 30 is formed.

The central control unit 70 analyzes the information data transmitted from the remote control monitoring unit 30 and displays the interpreted information, and the remote control monitoring unit 30 or the control unit which is a corresponding component based on the analyzed information (50) transmits an operation command.

In addition, the central control unit 70 receives the processed data, displays the received information, receives an on/off operation command of various electric devices or electric machines, and automatically registers an external or on-site monitor or register when an emergency condition occurs. It is also possible to notify the emergency situation through the user's smart phone, etc. Since the configuration and operation related to the above are already known techniques, a detailed description thereof will be omitted.

The LoRA gateway 40 collects and stores the information (temperature, humidity, harmful gas concentration, etc.) of the livestock 10 from the LoRA gateway 40 to the remote control monitoring unit 30, which performs the same role as above, so that LTE or Ethernet network transmit using That is, the LoRa gateway 40 collects the information inside the livestock house 10 and transmits it to the remote central control unit 70 , and the central control unit 70 can receive it through the mobile phone 80 .

As shown in FIG. 3, in order to implement a communication protocol optimized for the environment of the livestock house using LoRa communication, not only the star type network, which is the basic structure until recently, but also the mesh type network. configuration is possible.

Referring to FIG. 4 , the LoRA gateway 40 and the controller 50 are connected through a WAN (broadband network) of ISM frequency communication. In other words, broadband communication is possible, and an Internet of Things (IoT) communication network that can transmit and receive up to 20 km is applied. Therefore, accurate and rapid delivery is possible.

Accordingly, the control unit 50 has a fan motor 55 built therein, and the remote control monitoring unit uses the LoRa gateway 40 to provide information on the state and temperature and humidity of the fan motor 55 through the LoRa gateway 40 . It also serves to transmit to (30).

In order to perform the above functions and roles, the control unit 50 is further equipped with a LoRA communication module (M). To explain this, as shown in FIG. 5, the LoRA communication module M includes one or more input/output terminals 61 for inputting and outputting control signals, and a converter 57 for mutually converting a 485 communication signal and a LoRA-based protocol wireless communication signal. ) and a module transmitting/receiving unit 56 having an antenna (not shown) so as to be wirelessly communicated with the network and connected to a LoRA wireless communication network (not shown).

The module transceiver 56 may be configured to include a shared chipset for LoRa communication (not shown), and well-known elements may be applied to the chipset and antenna.

In addition, the LoRA communication module (M) has an effect of enabling integrated control by transmitting and receiving a relatively small amount of data to and from each device disposed in a specific area and connected by wire or wirelessly.

Accordingly, as the control unit 50 operates, the fan motor 55 operates in conjunction with the thermometer and the hygrometer.

When explaining the temperature control of the thermometer and the hygrometer as an example, when the temperature inside the livestock house 10 is controlled, if the temperature is higher than the appropriate temperature, the temperature must be lowered, so open the ventilation port (not shown), 55) to discharge the hot heat inside the barn to the outside to lower the internal temperature of the barn 10, and when the temperature in the barn 10 is below an appropriate temperature, the fan motor 55 stops By closing the ventilation hole, it is possible to keep the internal temperature constant. A detailed description of a technique for operating the ventilation hole and the fan motor will be omitted since it is well known.

In addition, it is possible to control the ventilation inside the barn 10 by using the mobile phone (80).

Hereinafter, with reference to FIG. 6 , a method of controlling indoor ventilation inside the barn 10 using the LoRa gateway 40 and the mobile phone 80 will be described.

First, the mobile phone 80 transmits a control command to the control unit 50 of the livestock bar 10 for indoor ventilation to the LoRa gateway 40 through a mobile communication network and the Internet (S110).

Thereafter, the LoRa gateway 40 that has received the control command transmits the received control command to the controller 50 through short-range wireless communication (S120).

Thereafter, the control unit 50 operates according to the control command (S130).

For example, according to the control command, it is possible to open or close the ventilation device (not shown) inside the livestock house 10 , and to adjust the operating speed of the motor fan 55 . Accordingly, the ventilation device may be turned on/off according to the control command, or the amount of air blown may be adjusted in various stages.

And, the concentration of the harmful gas is measured through the sensor unit 20 in the livestock house 10 . (Step 2)

In the above step, the sensor unit 20 transmits the concentration data measured through the LoRa gateway 40 to the control unit 50 . When the concentration is higher than a certain concentration, the control unit 50 operates the fan motor 55 or operates an electric device such as a fan to discharge it to the outside.

Then, as a next step, the LoRa gateway 40 monitors the temperature and humidity inside the livestock house 10 and transmits it to the monitoring unit 30 . (Step 3)

Therefore, it is preferable that the monitoring unit 30 sets numerical ranges of constant temperature and humidity in advance.

When it is determined that the temperature and humidity exceed the numerical range in the control unit 50, the control unit 50 adjusts it within the numerical range, and the method of opening and closing the horn by driving the fan motor 55 described above or an administrator By taking a certain action through the mobile phone 80, it serves to control so that the temperature and humidity are always constant.

In the next step, the remote control monitoring unit 30 detects the state of the fan motor 55 formed in the control unit 50 at regular intervals and notifies the central control unit 70 . (Step 4)

If the central control unit 70 receives a message from the remote control monitoring unit 30 that the fan motor 55 is not in a normal state and is in a state such as a failure, the central control unit 70 sends the mobile phone 80 to the person in charge or the manager without delay. It is to notify the person in charge or the manager with an alarm such as a notification or a text message so that the inside of the livestock bar 10 can be controlled through the mobile phone 80, or an appropriate action can be taken so that maintenance can be performed at all times.
