Accordingly, the system can more sensitively sense the delivery of the piglet, accurately remove all external elements detected, and perform bi-directional communication and control through the user terminal, thereby allowing a user to conveniently check the information on a pregnant pig to enable a manager to intensively manage and predict a management point, so the profits of a pig farm can be increased.

Description

[0002] The present invention relates to an IT convergence-type delivery and dystocia detection system,

In the present invention, a pressure sensing pad is installed at a position where a piglet is confined to a sowing house of a pig farm, and a sow is detected, and a dystocia is detected according to a delivery period to detect a result And an IT fusion type delivery and dystocia detection system capable of transmitting and receiving.

At birth, piglets do not have immunity and energy is insufficient to maintain body temperature, so pigs that do not consume colostrum over 15 to 20 hours after birth will have hypoglycemia and become highly susceptible to infection by pathogens. In addition, colostrum has a low absorption rate in the intestine after 19-22 hours of age, so it should be as fast as possible within 3 hours. Therefore, it is an important management point of infant mortality to allow infants to eat enough colostrum as soon as possible.

Generally, when piglets are born, piglets that are born as a result of suffocation are frequently produced. When the piglet is born in a housewife state, first clean the area around the mouth with a dry towel, shake the hind legs and back, remove the mucus that blocks the airway by centrifugal force, and help the baby to breathe. If not, we will reach our company. In case of pigs in the state of housekeeping due to a decrease in body temperature, the body temperature should be increased by warming in a temperature of 40 ° C or higher. If not, we will reach our company. In addition, administrators should be aware of the starting time of childbirth as soon as possible in order to reduce the mortality rate by treating infants in housekeeping condition well.

Also, if the sow interval of sows takes more than 30 minutes, there is a risk of dystocia. Therefore, if the delivery interval takes more than 30 minutes, it is necessary to inform the manager of the number of the object and the last delivery time so that he can take action against the discharge.

At this time, if the sow is not able to detect dysplasia even though the sow has suffered from dysmenorrhea, both sows and piglets are highly likely to die.

As a result, in the case of pig farms, it is very difficult to obtain high-quality manpower, but the majority of the poor manpower is covered by foreigners rather than domestic ones. In fact, most farms are giving up on the management of childbirth.

In this unfavorable situation, the present sows' labor and abortion are empirically confirmed through visual observation. Therefore, the burden of the manager is considerably increased, and it is necessary to develop a scientific automation system.

If the amount of work given to the supervisor is high, there is a considerable loss if the sow is started or the delivery is incurred in a situation where the sow being delivered or the sow being delivered is not observed and other work is required.

In order to solve the above problems, Korean Patent Registration No. 10-1431757 (Apr. 14, 2014) discloses a sow sowing and dystocia detection system for detecting spermatozoa of a sow and receiving a text message from an administrator.

However, conventionally, the detection of the delivery as a result of merely processing the value of the measurement sensor at the boundary value has a problem in that many kinds of disturbance elements generated in the actual field can not be removed and many malfunctions occur.

In addition, in the related art, when the shape of the pressure sensing pad can not be maintained according to the space or the position of the position of the pressure sensing pad when the pressure sensing pad is installed, one side of the pressure sensing pad may be pressed, The voltage signal of the sow was continuously detected and a malfunction occurred in which the sows were not able to detect labor and dystocia.

In addition, since the conventional delivery and dystocia detection system only detects one-way communication through transmission of a text message through the public network by sensing spermatozoa and dystocia of sows, it can not detect malfunction of the detection sensor or control module, Problems that can not be managed by the system are caused.

FIG. 3 is a flowchart showing an IT convergence type delivery and dystocia detection system according to an embodiment of the present invention, and FIG. 4 is a signal analysis graph of the controller according to FIG.

3 and 4, when the APP 21 installed in the user terminal 20 is started to start the detection system, signals of the user terminal 21 and the transmission / reception modem 130 are checked, Power can be supplied to the pressure sensing pad 110 and the controller 120 and the state of the pressure sensing pad 110 and the controller 120 can be checked. Also, when the pressure sensing pad 110 and the controller 120 start to operate normally, the controller 120 transmits a normal operation signal to the user terminal 20.

In addition, through the APP 21 installed in the user terminal 20, the user can input a setting value for determining the delivery and determining the dispensation of the controller 120. At this time, the set value may include a unit time, a reference set time, a period of dysthymia, a maximum sow count, and the like. (S1 to S2)

Further, a value obtained by differentiating the variation amount per unit time of the signal inputted from the pressure sensing pad 110 is set as a reference value, and when the signal exceeding the set reference value is input, it is determined as an external signal. At this time, the unit time can be set through the user terminal 20. If the unit time is set to a low value, the controller 120 can measure more accurately. However, as the value of the unit time is smaller, the CPU 124 is required to perform more calculations, and therefore, the unit time is preferably set to 1 minute. In addition, through the dynamic pressure analysis as described above, one side of the pressure sensing pad 110 may be folded by the vibrations generated when the pressure sensing pad 110 is installed, , It is possible to judge the malfunction in which a certain level of voltage signal is detected due to continuous pressure, thereby eliminating the ambient noise or internal noise around the delivery space, which is not an external signal related to the delivery of sows, There is an effect. Further, the reference value may be further stabilized by performing a second derivative process on the detection signal received from the pressure sensing pad 110. (S7)

If the sum of the delivery signals is less than the maximum number of piglets set by the user and the delivery interval becomes longer than the dyssynchronization cycle, And transmits the dyssense detection information to the user terminal 20. Further, when the sum of the delivery signals is equal to or greater than the maximum number of piglets set by the user, and the delivery interval is equal to or longer than the dyssynchronization period, it is determined that delivery is completed. At this time, the above-mentioned interval of dystopia can be set to 30 minutes, and according to the condition of the spermatozoa or sow, the administrator can set the duration of dystopia and the maximum number of deliveries of the sows to an appropriate time (S11 to S13)
