DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, embodiments of a method and apparatus for managing a housing environment using a temperature and humidity index according to the present invention will be described in detail with reference to the accompanying drawings, wherein like reference numerals refer to like elements And a duplicate description thereof will be omitted

1 is a schematic view illustrating an operating structure of a housing environment managing apparatus according to an embodiment of the present invention.

2 shows an external structure of a housing environment management apparatus according to an embodiment of the present invention.

1 and 2, a housing environment management apparatus 10 according to an embodiment of the present invention includes a sensing data input unit 15 (hereinafter, referred to as a sensing data input unit) receiving sensing data from a temperature and humidity sensor 51 installed in the housing 1, A display screen 18 for outputting input and output results, a keypad unit 13 for inputting management conditions and a command of the user, a data input unit 15 and a keypad unit 13, A facility control output unit 12 for sending a drive control signal of an environmental facility according to a control signal of the control unit, And a data transmission unit 11 for wirelessly transmitting data and output results and facility control status.

The sensing data input unit 15 is connected to the temperature and humidity measuring apparatus according to an embodiment of the present invention and receives a measurement value.

According to another embodiment of the present invention, the input unit may further include an infrared ray camera 52 for measuring the body temperature of the livestock.

According to one embodiment of the present invention, the main body includes a display screen 18, a control unit built in the keypad unit 13, and the like.

In the display screen 18, temperature, humidity, temperature and humidity index (THI), temperature and humidity index including livestock heating value, and housing facility control status are outputted.

In the control section, the thermal stress, temperature and humidity index (THI) calculation formula applicable to each axis type and breeding stage is built in.

According to an embodiment of the present invention, the controller may calculate a second THI value to be applied to the actual facility control by considering the first THI value according to the selection condition of the administrator and the addition value according to the calorific value of the livestock.

In addition, the control unit incorporates a thermal stress temperature and humidity index (THI) calculation formula applicable to each livestock.

In addition, when the controller inputs a separately inputted thermal stress temperature and humidity index (THI) calculation formula, the controller stores it and selects a thermal stress temperature and humidity index (THI) calculating formula suitable for the livestock, And calculates a THI value.

According to an embodiment of the present invention, the controller calculates a first THI value based on the measured temperature and humidity, calculates a second THI by calculating a calorific value generated from the domestic animals in the housing 1, , The operation order and the drive control value of the environmental facility equipment of the housing are determined to control the environment of the housing.

3 is a flowchart showing a method of controlling a storage environment management method by the control unit of the storage environment management apparatus.

In step 110, the control unit receives the humidity conditions from the sensing data input unit 15.

In step 120, the first heat stress temperature and humidity index (first THI) applied to the livestock is calculated from the inputted temperature and humidity conditions.

Various experiments on the heat stress of livestock are caused by environmental factors. Environmental factors include not only the temperature but also the relative humidity and radiant heat itself.

However, since the available data are limited and the self-generated heat is difficult to pattern uniformly, the heat stress temperature and humidity index (hereinafter referred to as "THI"), which affects the development and rearing of livestock, .

For example, in the case of cattle or dairy cattle, the first thermal stress and temperature and humidity index can be calculated from the measured temperature and relative humidity using the following THI calculation equation.

First THI: [(1.8 x dry bulb temperature + 32) - 0.55 (1 - relative humidity / 100) x (1.8 dry bulb temperature - 26)

The THI calculation formula can be applied differently depending on the type of livestock. Accordingly, in step 120, the first THI can be calculated by applying a suitable THI calculation formula to the livestock.

In case of one or two animals, the first THI calculated by the above approximate formula is applied to compare with the appropriate THI to determine the actual degree of thermal stress, and it is possible to control the housing environment in the appropriate THI range by driving the environmental facility equipment have.

However, when large-scale livestock are raised, the heat stress that affects the livestock rearing can not be ignored by the heat generated by the livestock itself.

In the step 120, which is one embodiment of the present invention, the sensible heat value of the whole livestock is calculated based on the body surface temperature of the livestock measured by the infrared ray camera 52 or the body temperature of the inputted livestock.

Next, in step 130, the degree of heat sensation of the livestock in the step 120, which affects the heat stress of the livestock, is calculated from past accumulated data to calculate a sum to be applied to the THI.

For example, in step 130, the sensible heating value of the entire livestock is calculated on the basis of the body temperature of the infrared ray camera 52 or the inputted livestock. Then, in step 140, the degree of influence on the THI value Is calculated from the past accumulated data, and the added value is calculated.

The addition value is applied to the first THI in step 150 to calculate an appropriate second THI value that can be applied to the actual housing. That is, the second THI value using the addition value is calculated for the first THI value calculated based on the ON and the humidity.

For example, when raising only the existing temperature, the optimal raising temperature of the cow is known as 5 ~ 24 ℃. However, when the humidity is high, the livestock can be exposed to the stress environment even at the appropriate rearing temperature.

For example, if the relative humidity is 80% at 22 ° C, where the housing internal temperature corresponds to the appropriate rearing temperature, the first THI value is calculated by the above THI calculation formula as follows.

First THI = (1.8 x dry bulb temperature +32) - (0.55-0.0055 x relative humidity) x (1.8 x dry bulb temperature -26) = 70.1

In the case of dairy cows, it is reported that they are subjected to heat stress from a heat stress temperature and humidity index of 68 or higher.

Therefore, it can be seen that the first THI is 70.1, which is already subjected to slight thermal stress even at 22 占 폚 corresponding to the optimum growing temperature.

According to one embodiment of the present invention, when the THI value exceeds 98, it can be judged that the animal can be killed, based on data and experimental data reported in the past. When the THI value is 68 or more, .

In addition, if the THI is 68 to 78, it is judged as the first influential stress level. If the THI is 79 to 89, the intermediate stress is evaluated. If the THI is 89 or more, the severity is evaluated as the stress level. do.

According to an embodiment of the present invention, since a large number of herds are raised, a process of correcting the first THI is performed by obtaining an addition value based on the calorific value of the livestock that affects the heat stress of the livestock.

For example, if the number of cows raised is 100, the amount of sensible heat generated is about 150Wh per kg of kg, based on 60kg of finishing pigeons, and about 15kWh of sensible heat is generated when 100 is added .

When the additive value is obtained from the database in which the past experiential value for the sensible calorific value of heat of 15 kWh is stored at 22 DEG C, an additive value of 0.04 is calculated.

Accordingly, the second THI value to be actually applied using the sensible heat is calculated as 72.9 considering the above addition value at 70.1.

The heat stress effect index due to the sensible heating value of the livestock can be applied differently depending on the difference condition with the present temperature.

In one embodiment of the present invention, the control unit stores the past experience values applied to the cow body temperature at each temperature step and the degree of influence thereof on the heat stress temperature and humidity index, and calculates the additive value based on the sensible heat value have.

It is possible to control the environment more precisely if it is used as an additional variable of the environment control considering the calories generated according to the number of livestock.

In the next step 160, the facility equipment for changing the second THI value to the appropriate THI value is selected, and the supply and discharge amount is calculated to determine the drive control value of the facility equipment.

In step 170, control signals are transmitted to the selected equipment through the facility control output unit 3 according to the driving control values of the facility equipment.

In another embodiment of the present invention, the control unit may set threshold values (critical threshold values) for the THI control range of the housing facilities such as the ventilating unit, the thermostat, and the hygrostat for changing the calculated second THI value to a proper THI value And calculates and controls the drive control value in comparison with the current control state.

That is, the drive control value is calculated by comparing the control value obtained by applying the threshold control value to the difference between the second thermal stress / humidity index and the optimal thermal stress / humidity / humidity index, with the current drive control state.

Also, this threshold value may be arbitrarily set by the user.

For example, if the temperature is below the threshold, the air conditioning system can be turned on by reducing the amount of ventilation and activating the heating system, and increasing the amount of ventilation if the temperature exceeds the threshold. Also, if the value for the humidity is high and the difference THI value for the appropriate THI value is high, the dehumidifier can be operated to reduce the heat stress.

In step 180, the first and second THI values and the operational status information of the facility equipment are transmitted to the manager.

Alternatively, according to an embodiment of the present invention, when the temperature, the humidity, and the second THI value deviate from the set threshold value, a function of notifying the manager through the data transmission unit 4 may be included.

The data transmitting unit 4 receives the second heat stress temperature and humidity index (including the second THI (first THI) and the second heat load humidity index (second THI) including the in-house temperature, humidity, ) And housing facility control status.

According to an embodiment of the present invention, the environmental control management of the housing is performed in consideration of the heat stress, temperature and humidity index and the calorific value of the livestock, thereby providing a pleasant environment in which the livestock is kept from being stressed.
