The wireless relay module 300 receives the irrigation control signal from the automatic irrigation integrated controller 200. In addition to the irrigation control command, the irrigation control module 500 checks the control status of irrigation and whether the irrigation control ends or continues. send.

Commands and responses from the wireless relay module 300 to the automatic irrigation control module 500 are interconnected by the automatic irrigation wireless module 400 acting as a medium.

In addition, the automatic irrigation wireless module 400 and the automatic irrigation control module 500 are devices that serve as slave irrigation control.

Furthermore, referring back to FIG. 1, as one master device consisting of the automatic irrigation integrated controller 200 and the wireless relay module 300 described above, the automatic irrigation wireless module 400 and the automatic irrigation control module ( 500) is configured so that a plurality of n slave devices can be connected.

In addition, the wireless communication method between the wireless relay module 300 and the automatic irrigation wireless module 400 is to perform two-way communication by being connected by a wireless mesh network, FIG. 5 shows the wireless mesh This is a picture to explain the network. Hereinafter, the wireless mesh network method will be briefly described with reference to the drawings.

In general, it is a typical wireless LAN environment in which a device called a wireless access point (AP) can use the Internet, etc. by using a wireless frequency called 24 GHz for wireless devices such as a notebook PC or a PDA.

In the picture on the left, the existing wired network environment is called an access point (AP), and signals are connected through a repeater or wireless router, and all APs are connected by wire. If you look closely at this, only the AP and the laptop terminal are wireless sections in the wireless section, and the system (Switch) that exchanges actual data with the AP is connected by wire.

Here, when the wireless mesh network applied to the present invention is introduced, it is changed as shown in the picture on the right. At this time, instead of the cable connected to the AP, a system constituting a wireless mesh network called a mesh node enters, so that all sections can be made wireless.

That is, in the wireless mesh network in the picture on the right, when only the representative access point (AP) is connected by wire, wireless communication routers (devices that connect different networks) that act as antennas, like the existing wireless communication base stations, are meshed with each other. It becomes a node and connects all sections wirelessly. Therefore, by overcoming the limitations of the existing wireless LAN, the user can use the entire integrated organic network with a procedure similar to connecting to Wi-Fi.

Therefore, as described above, the master wireless relay module 300 and the slave automatic irrigation wireless module 400 communicate with each other in both directions, so that organic and efficient communication is possible with each other through a more advanced wireless network environment.

The automatic irrigation control facility 600 is controlled by applying an irrigation control signal through the automatic irrigation wireless module 400 and the automatic irrigation control module 500 corresponding to slaves.

Referring to FIG. 6 , an electromagnetic valve 610 and an irrigation motor 620 are formed in the automatic irrigation control facility 600 . The solenoid valve 610 is a valve attached to a water pipe (not shown) that irrigates water or nutrient solution from a water storage tank (not shown) containing irrigation or nutrient solution or supplies nutrient solution to the target land, etc., and an automatic irrigation control module ( 500) and Bluetooth, Wi-Fi, NFC, etc., to supply water to the field through the wireless irrigation supply device according to the present invention at preset time intervals according to the operation and control of the automatic irrigation control module 500. is to make it possible

That is, the solenoid valve 610 is for water irrigation control, and is attached to and installed on the water pipe to control the amount of water supplied through opening and closing of the water pipe.

In addition, the manager or operator can control the opening or closing as well as the water supply time of the solenoid valve 610 through the terminal 120 formed on the integrated control platform 100 .

In addition, the irrigation motor 620 is a device that provides power for supplying water, so that the water contained in the raw water bucket (not shown) can be supplied to the field. Furthermore, the suction motor 630 is also formed and serves to suck air.

Referring to FIG. 8, as described above, in order to protect the automatic irrigation apparatus according to the present invention, there is a function of monitoring using the irrigation information analysis algorithm.

This is because, if there is no water in the water tank for storing the nutrient solution or raw water in the automatic irrigation device, the irrigation motor 620 will idle and the irrigation motor 620 may malfunction. In addition, if the supplied water pipe (not shown) pressure is too large, it is because the failure of the facilities constituting the water supply supply device may result.

Therefore, by analyzing the operating state of the wireless automatic irrigation device according to the present invention, the analysis algorithm by the irrigation control application software 150 of the integrated control platform 100 described above is applied to the raw water bucket through the pressure gauge 731 . It recognizes the pressure information of the contained raw water and controls it when the pressure is high. For reference, the irrigation control application software 150 includes information of the raw water pressure contained in the raw water bucket, water level information, irrigation flow rate information, pressure setting of the solenoid valve 610, and basic information of irrigation facilities in the form of data. there will be

This is to prevent the irrigation motor 610 from idling by recognizing the water level information of the raw water bucket through the water level gauge 732 . Therefore, a water level sensor is formed in the water level gauge 732 to recognize it, and to recognize a situation in which there is no water or a certain level of water above a certain level and notify the integrated control platform 100 .

The flow rate information of the water supplied through the flow meter 733 is recognized, and if it is too different from the flow rate set in advance as a reference through the flow rate for a certain period of time, it can be notified.

Through the irrigation facility basic information unit 734, the entire basic information such as the location of the irrigation facility and the slope with respect to the ground is grasped.

And, the solenoid valve 610 installed in the water supply pipe (not shown) is to automatically close when the pressure detected by the pressure sensor (not shown) rises to a set pressure.

In addition, a power storage device 820 for storing the power generated by the solar panel 810 is included. The power storage device 820 is a battery and serves as a storage battery for storing the generated power.

The power storage device 820 can measure the amount of power generated through the stored power, detect the amount of power generated by the solar panel 810, and control the operation of the integrated control platform 100 when a set power generation value is reached.

The power converter 830 refers to a device that converts electricity produced by the solar panel 810 into power for irrigation control and outputs it, and has a structure formed by including a converter 831 and an inverter 832 therein. . The converter 831 is a device that level-converts AC power produced by the solar panel 810 and outputs it as DC power, and the inverter 832 level converts the DC power output from the converter into AC power. It means a device that outputs

In addition, the voltage monitoring unit 840, as shown, is connected to the inverter 832 and the power storage device 820, and when all the power of the power storage device 820 is exhausted, the grid-connected type It may be a device that converts power into electricity.

Furthermore, it further includes a connection-type power conversion unit 850, which is connected to an external grid power source, converts the electricity supplied from the grid power source into power for irrigation control, outputs it, and transmits it to the voltage monitoring unit 840. it is a device

Therefore, even if all the power of the power storage device 820 is exhausted at a specific time when a lot of irrigation is required due to the connected power converter 850, electricity supplied from the grid power can be used. Therefore, since the power device using solar heat is used, it is possible to reduce the cost used for power.

Hereinafter, with reference to the drawings, a method for controlling the irrigation supply using the on-site wireless irrigation supply device of the present invention will be described. A description that overlaps with the above description will be omitted to some extent.
