The present invention relates to a livestock shed monitoring system monitoring the deodorization and health condition of livestock, and a livestock shed monitoring method. The livestock shed monitoring system comprises the following: a deodorization gas generator generating deodorization gas mixed with oxygen more than one deodorization gas inflow pipe inflowing the deodorization gas a deodorization gas spraying pipe spraying the deodorization gas into a livestock shed more than one camera for taking images of inside and outside of the livestock shed multiple heat detection sensors photographing the health condition of livestock multiple ammonia sensors detecting ammonia gas multiple mercaptan sensors detecting mercaptan gas a fire detection sensor a temperature sensor a power supply unit generating operation power by receiving AC commercial electricity a livestock shed monitoring terminal wirelessly monitoring the health condition of the livestock, the temperature of the livestock shed, the concentration of the ammonia gas and the mercaptan gas, and a video signal of the livestock shed and a controller generating a blowing pan control signal and an oxygen generation operation signal by the concentration of the ammonia gas and the mercaptan gas, and generating a heater operation signal when the temperature detected by the temperature sensor is lower than the preset temperature.COPYRIGHT KIPO 2014[Reference numerals] (102) Camera(104) Heat detection sensor(106) Ammonia sensor(108) Mercaptan sensor(110) Fire detection sensor(112) Temperature sensor(212) Oxygen generator(213) Ventilation fan(214) Heater(215) Compressor(218) Moisture collecting unit(301) Storage battery(302) Power supply unit(303) Controller(304) LAN communication unit(305) Livestock shed monitoring terminal(306) Internet(307) Mobile communication network(308) Smartphone본 발명은 축사에 탈취개스를 분사하여 냄새를 제거하고 가축의 건강상태 및 축사의 동영상신호와 암모니아개스 농도값과 메르캅탄 개스 농도값 및 축사의 온도값을 원격으로 감시하는 축사감시 시스템 및 그 축사 감시방법에 관한 것이다.축사에서 발생하는
