Description

TECHNICAL FIELD [0001] The present invention relates to a management system for a farm management system having a wireless network structure,

The present invention relates to a farm management system, and more particularly, to a farm management system that uses the electric power generated from natural energy to transmit measurement values of sensors installed in a plurality of water tanks in near field wireless communication, The present invention relates to a farm management system having a wireless network structure capable of remotely supporting a farm environment management based on a sensor value.

In general, water quality factors of fish farms are dissolved oxygen concentration, water temperature, pH (pH), ammonia concentration, nitrogen compound concentration, nitrite concentration, and turbidity. Among them, dissolved oxygen concentration and water temperature are the most important factors. The major pollutants that deteriorate the water quality of fish farms are the excrement and carcasses of the farmed fish, and the remaining feed left over. In other words, pollution sources are a necessary evil that can not be avoided. Therefore, it is impossible to block them. It is necessary to monitor measures of water quality continuously, remove pollutants in a timely manner, and take measures to improve water quality.

Primitive water quality improvement measures include oxygen penetration that causes oxygen in the air to dissolve by generating a foam by disturbing the water stored in the pond using an agitator, and adjusting the mixing ratio of hot and cold water in the water to be introduced, Water temperature control for heating, removal of contaminated water from the pond, replacement of water for inputting fresh water, and cleaning of the pond to periodically remove contaminants that have settled on the bottom of the pond.

Oxygen infusion and water temperature control are very important, so instead of injecting oxygen in the air to optimize the quality of the water, it is necessary to introduce high purity oxygen, or to use an additional heater or boiler to improve performance Is required. The cost of water replacement and cleaning of the pond is not so small, so research and efforts have been made to increase the efficiency or to provide alternatives.

In recent years, a methodology has been proposed for improving the productivity of high-quality fisheries by optimally adjusting the growth conditions necessary for raising fish, and for efficiently managing the fish farms.

Figure 1 shows a conventional fish farm remote management system. As shown in the figure, means (210) for acquiring observation information related to the pond water quality management system (100, 100 ', 100 ") and the environment around the pond and the pond and observation information about the situation in each pond (220, 220 ', 220 "). The pond water quality management system 100, 100 ', 100 "is connected to the main controller 300 and the main controller 300 is connected to the fish farm control computer 400.

A personal computer (PC) is used as the fish farm control computer 400, and a control system based on a microprocessor is used as the main controller 300. The observation information obtaining means 210, 220, 220 ', 220 "includes at least one CCD camera installed to capture the fish rearing condition around the fish farm, the inside and outside ponds, and the fish farm control computer 400 , An infrared sensor for intruder detection, and the like.

Each of the pond water quality management systems 100, 100 ', 100 "described above are all constituted identically, each of which comprises oxygen inserting means for dissolving oxygen in the water, water temperature adjusting means for heating or cooling the water, An input unit used for inputting a set value and an allowable limit of a required water quality condition, a water purification system for removing pollutants in the pond and purifying the water, and a set value of the water quality input from the input unit, And a pond water quality controller for timely activating each of the oxygen infusion means, the water temperature control means and the water purification system in accordance with the limit and the water quality condition sensed by the sensor.

Therefore, it is possible to greatly reduce the amount of wastewater generated and to significantly reduce costs such as water cost and personnel cost by regenerating and using the water without replacing the water, but the rate of occurrence of dead fishes or diseases is greatly reduced, The growth conditions of the fish can be tailored and the productivity of the fish is greatly improved.

However, in the fish farm remote management system, since the fish farm management is performed by using each water quality management system and a plurality of CCD cameras, a large number of electric wires are used in the fish farm so that there is always a risk of electric shock to the fish . In other words, it has been pointed out that there is a lack of stability in application of fish farm remote management system to the field, and there is also pointed out that a lot of power is consumed in farm operation.

Therefore, it is imperative to implement a system that can secure the stability of the fish farm management by using the minimum power for remote management of the fish farm but using the direct current power so as not to cause direct dangerous situation to the fish farm.

As shown in the figure, a sensor module 213 includes at least one water tank 211 for culturing fish, a plurality of state sensors for sensing the state of each water tank, A control module 217 for controlling the feed, oxygen, and water temperature of each of the water tanks, and a control module 217 for controlling the operation of the control module 217, A local area communication router 223 for performing local area communication between the communication module A 215 and the communication module B 219 for communicating with the local communication router 223, A hopping controller 221 for preventing communication communication between the modules and a short distance communication router 223 connected to the short distance communication router 223 in a wired or wireless manner for performing long distance communication and detecting information detected by the sensor module 213, The control module 217 And a telecommunication router 225 for providing a working state to the computer 231 or the mobile communication terminal 233 of the manager.

Here, the computer 231 and the mobile communication terminal 233 are installed with an application for fish management. The computer 231 and the mobile communication terminal 233 are equipped with an application for fish management, and are provided with information on predetermined water temperature, dissolved oxygen amount, nutrient salt, acidity and turbidity according to the type of fish, age, Reference value information is provided. Therefore, the sensor module 213 uses a water temperature sensor, a dissolved oxygen amount measuring sensor, a nutrient salt measuring sensor, an acidity measuring sensor, and a turbidity sensor.

In addition, the type and age of the fish described above are set by the administrator, and the activity amount of the fish can be assumed as the vibration energy of the water in comparison with the capacity of the water loaded in the water tank, the average weight of the fish, and the number of fish. That is, the sensor module 213 further includes a pressure sensor for measuring the water wave, and calculates the vibration energy, that is, the activity amount of the fish based on the average value of the pressure change measured by the pressure sensor.

Meanwhile, any one of Bluetooth, ZigBee, and NFC communication modules may be used for the communication module 215 and 219 for short-range communication according to the present invention. In addition, the electric power for starting the aquaculture management system used in the present invention converts renewable energy such as solar energy or wind energy into electrical energy for use.

Also, the power state of the renewable energy is communicated to the local communication router 223 by using a separate communication module, so that monitoring of the power state is performed remotely.

3 is a block diagram for explaining major functions of the aquaculture management system according to the present invention.

As shown in the figure, the sensor module 213 includes a water temperature sensor 313 for measuring the temperature of the water in the water tank 211, a dissolved oxygen sensor 315 for measuring the dissolved oxygen amount, A nutrient salt sensor 317, an acidity sensor 319 for measuring the acidity, a turbidity sensor 321 for measuring the turbidity of the water, and a pressure sensor 311 for measuring the activity of the fish as a wave condition for the water And a data processing unit 323 for performing AD conversion of information detected from each sensor and signal processing of data.

The signal processing of the data processing unit 323 converts digitized data through AD conversion according to a communication protocol of the wireless communication module 215 and includes unique codes and measurement information for each sensor And processed into serialized information. The data processor 323 receives the signals measured from the sensors by the water temperature sensor 313, the dissolved oxygen sensor 315, the nutrient salt sensor 317, the acidity sensor 319 and the turbidity sensor 321, And processes the information according to the communication protocol. However, in the case of the pressure sensor 311, the vibration of the water, that is, the activity of the fish, is measured, and the change of the water pressure measured for a predetermined time, for example, 12 hours or 24 hours is detected .

The data processing unit 323 calculates the average value of the measurement data of the pressure sensor 311. [ The average value measurement result of the pressure sensor 311 is processed into formatted information including a unique code and is processed according to the communication protocol as the measurement results of the various sensors.

Meanwhile, the control module 217 interlocks with the wireless communication module 219 to perform feeding of the fish, oxygen supply, and water temperature control. To this end, a feeder 333, an oxygen supplier 335, a water temperature controller 337 and a driver 331 are provided. The driver 331 is provided for the purpose of controlling the operation of each device.

For example, in order to operate the feeding device 333, the driver 331 provides a control signal corresponding to the feeding amount and feed time information, and the oxygen feeder 335 feeds the dissolved oxygen amount sensor 315 And the oxygen supply amount is set based on the measured dissolved oxygen amount and the water temperature regulator 337 controls to set the temperature based on the measured value of the water temperature sensor 313 and predetermined water temperature data . That is, the driver 331 operates each device precisely by control data for operating each device.

Accordingly, the wireless communication module B 219 receives the control signal for each device transmitted from the local area communication router 223, and controls the feeding device 333, the oxygen supplier 335, and the water temperature And controls the driver 331 to start the regulator 337.

In the present invention, the power used for each wireless communication module including various sensors and devices is provided from renewable energy. As shown in the figure, the photovoltaic power generator 343 for converting solar energy into electric energy, Or a wind power generator 345 for converting wind energy into electric energy. The energy supply unit 341 charges the energy generated by the energy supply unit 341 in a separate battery, converts the energy into a rated power, A control management unit 351 for detecting the state of charge and power supply of the battery and a wireless communication module C (for example, a wireless communication module) for transmitting the charging status and power supply status information detected by the control management unit 351 to the short- 353).

The photovoltaic power generation unit 343 is a power generation unit that receives power from a plurality of solar cells, and the number of the wind power generation units 341 is determined corresponding to power consumption as a small wind power generator. Therefore, the control management unit 351 rectifies the power supplied from the energy supply unit 341 to the DC power source, and then processes it into the charging voltage of the battery through the rated output circuit.

The power supplied from the battery is varied according to the rated voltage of each device or sensor, and then power is supplied. Further, it extracts the power supply information regarding the output voltage of the battery, the charging voltage, the power consumption, and the like, and provides it as the coded information to the wireless communication module C (353).

The operation of the thus structured farm management system will now be described in detail with reference to the accompanying drawings. 4 is a flow chart for explaining main operations of the present invention.

First, the installation and setting of the system is performed through the initialization process of step S401. That is, the solar power generator 343 or the wind power generator 341 is used as the energy supply unit 341, which is installed outdoors. A water temperature sensor 313, a dissolved oxygen amount sensor 315, a nutrient salt sensor 317, an acidity sensor 319, a turbidity sensor 321 and a pressure sensor 311 are mounted in the water tank 211. These various sensors are connected to the data processing unit 323, convert the signals detected from the respective sensors into digital signals, and process them into data corresponding to a predetermined communication protocol.

The control module 217 includes various sensors and the control module 217 includes a feeder 333, an oxygen supplier 335, and a water temperature controller 337 . The feeder 333 is a device for automatically feeding fish to the fish, and the oxygen supplier 335 is a device for increasing the dissolved oxygen amount by supplying oxygen to the water in the water tank. The water temperature controller 337 is a device for increasing the temperature of the water. Each of these devices is controlled through a driver 331, and the driver 331 is connected to the wireless communication module B 219.

In step S403, the computer 231 or the mobile communication terminal 233 downloads an application for managing the farm. The application is a program for remote management of farms over long distances. When downloading the application, the manager registers management information through the computer 231 or the mobile communication terminal 233 in step S405. To do this, the administrator first sets the number of tanks and registers the unique number for each tanks.

In addition, information on the type, age, and object number of fish loaded in each tank is registered. In step S407, the application provides an appropriate water temperature, an appropriate dissolved oxygen amount, an appropriate nutrient salt, a suitable acidity, and an appropriate turbidity corresponding to the type and age of the fish set in step S407. Activity information on the fish can be provided as a reference value, which means that the activity of the fish, as described above, represents the surface pressure change of the water due to the activity of the fish in the water tank.

That is, after the pressure sensor 311 is installed directly below the water surface, the vibration state of the water surface due to the fish activity is measured by the averaged information. If the fish activity is high, the average pressure per unit time will be high. If this is the case, the average pressure per unit time will be low. Using this principle, the amount of fish activity in the normal reared state is provided as numerical information to determine whether the activity level of the fish is normal.

Since the above-described fish activity amount varies depending on the size of the water tank including the number of objects of the fish, the type and age of the fish, and the capacity of the water, the reference value information thereof will be based on the experimental results. Accordingly, in the management information registration procedure, the administrator inputs the size of the water tank and the capacity of the water including the number of objects, the type and the age of the fish, and determines whether the current fish activity amount corresponding to the reference value information is normal.

The process goes to step S409 to supply power to the farm management system. System power is generated and supplied by the solar power generator 343 or the wind power generator 345. The solar power generator 343 generates electric energy using a plurality of solar cells installed outdoors, and the wind power generator 345 is generated by a separate wind power system installed outside. If necessary, the solar power generator 343 and the wind power generator 345 may be operated simultaneously.

The control management unit 351 regulates power for the power generation system, charges the rechargeable battery with spare power, and monitors power consumption and charging power. Therefore, the control management unit 351 converts the power generation energy of the power generation system into the rated power and supplies it to each sensor and devices. The monitoring results of the power consumption and the charging power are provided to the personal computer 231 or the mobile communication terminal 233 through the wireless communication module C 353.

On the other hand, in step S411, since the power provided from the control management unit 351 is supplied to each sensor and device, each sensor continuously detects the state in the water tank. In other words, the water temperature sensor 313 measures the water temperature of the water tank, the dissolved oxygen sensor 315 measures the dissolved oxygen amount in the water tank, the nutrient salt sensor 317 measures the nutrient salts, and the acidity sensor 319 The turbidity sensor 321 measures the turbidity of the water, and the pressure sensor 311 measures the pressure change corresponding to the activity of the fish.

At this time, the data processing unit 323 sequentially collects the result information detected from each sensor. This collects data consisting of the unique code of the sensor and the detection result information for each sensor. Of course, the detection result information may be formed in a serial manner according to the order of the sensor without using the inherent code of the sensor according to need.

Thereafter, the data processing unit 323 provides the detection result information measured from each sensor to the wireless communication module A 215, and the wireless communication module A 215 transmits the detection result information according to the near field communication protocol . The detection result information is transmitted to each water tank, and the data processing unit 323 will provide a unique code for each water tank.

The detection result information for each sensor sent from the wireless communication module A 215 is sent to the local area communication router 223 at which the hopping controller 221 hopes detection result information originated from at least two tanks. That is, in step S413, the hopping controller 221 divides a frequency band for short-range communication into a predetermined frequency band, and sequentially communicates the wireless communication module A 215 provided for each water tank, prevent.

In step S415, the local area communication router 223 performs communication with the remote area communication router 225. The local area communication router 223 includes a separate communication module for wired / wireless remote communication.

The remote communication router 225 receives the detection result information for each sensor and each sensor from the local area communication router 223. The telecommunication router 225 transmits detection result information to the personal computer 231 or the mobile communication terminal 233 through the Internet communication or the wireless communication network.

In step S417, the personal computer 231 or the mobile communication terminal 233 provides the detection result information for each sensor and each sensor on the screen provided by the application, Information is displayed. This can be provided as digitized information, but it would be desirable to be provided as graphical information to guide the manager's quick judgment.

FIG. 5 shows an application of the mobile communication terminal 233 shown in the embodiment of the present invention. As shown in the figure, the detection result information detected from each sensor of each water bath is provided as graphical information, and displayed together with the reference value information. The power generation state, the charging state, the power consumption state, and the like are displayed from the photovoltaic power generator 343 or the wind power generator 345, thereby improving the efficiency of management. In addition, when an abnormal condition occurs in a specific water tank, the warning lamp is immediately turned on, and at the same time, automatic control for problem solving is performed.

For example, when the water temperature in the water tank 5 becomes higher than the reference value, the warning lamp is operated and the water temperature controller of the water tank 5 is automatically operated. Also, when the amount of oxygen in the water tank 4 exceeds the reference value, the oxygen supplier of the water tank 4 is automatically operated.

The automatic control for each device is performed by the application. If the detection result information detected from the specific sensor in the specific water tank exceeds the reference value, the application provides an error message as in step S419. Then, remote control for each device is performed as in step S421 so that remote control according to the abnormal state is performed.

The remote control is to control a specific tank, a device corresponding to a specific sensor, and a control command instructed from an application is provided to the telecommunication router 225 via the Internet or a wireless communication network. The primitive communication router 225 transmits a control command to the local area communication router 223 using a wired / wireless communication network and the local area communication router 223 transfers the control command to each wireless communication module B 219.

Since the wireless communication module B 219 is provided for each water tank, the control command is provided to the wireless communication module B corresponding to the corresponding water tank. Then, the wireless communication module B (219) transmits a control command to the corresponding driver (331). The control command includes a unique code and control data set for each device. The on / off control, the operation range, and the like of the feeder 333, the oxygen supplier 335, and the water temperature controller 337 are set or controlled .

If it is determined in step S419 that no abnormality is detected in all the tanks, the flow proceeds to step S423 to maintain normal operation. Here, the normal operation means that the current state is maintained and that the oxygen supply is operated at a predetermined time unit or at a specific time according to the set program.

As described above, the aquaculture management system according to the present invention monitors the water tank condition with low power by near-field communication, thereby enhancing the breeding stability of the fish and remote management and control of the administrator based on the long distance communication.
