The comfortable body temperature of lactating piglets is higher than that of lactating sows, and there is a large difference between the two. The health status of lactating piglets is closely related to the growth level and environmental factors. Lactating piglets cannot completely rely on their own body temperature regulation at birth, and are very sensitive to environmental temperature and relative humidity.

DETAILED DESCRIPTION

[0058] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all the embodiments.

A plurality of power supply output ends are also arranged on the heat lamp controller 6. The wireless network is a wireless wifi communication.

[0062] The sensor module 4 is used to detect the environmental parameters of the pig house; the sensor module 4 is electrically connected with the environment controller 2. The sensor module 4 comprises a temperature sensor and a humidity sensor, wherein the temperature sensor is used to detect the environmental temperature of the pig house in real time, and the humidity sensor is used to detect the relative humidity of the pig house in real time; the environmental parameters are the environmental temperature and the relative humidity of the pig house.

[0063] The environment controller 2 is used to obtain the real-time environmental parameters detected by the sensor module 4, and is also used to control the fan 3 and the wet curtain 5 to work according to the environmental parameters and the set pig house temperature. According to the set pig house temperature and the change of the environmental parameters, the environment controller 2 automatically adjusts the operating power of the fan 3 and the wet curtain 5, cools the pig house, ensures that the temperature and humidity in the pig house are suitable, and thus improves the breeding efficiency; and transmits the real-time environmental parameters and the real-time ventilation volume of the fan 3 to the cloud service platform 1.

[0076] The piglet blowing module 8 is installed on the side of the sow stall frame, and the air outlet blows air towards the body of the sow in a standing state and close to the floor, so as to drive away piglets through the blowing high-speed airflow and avoid that the piglets are crushed to death by the sow when moving under the sow.

[0077] The lactating sow and piglet growth environment coupling linkage control system can record the environmental parameters of the whole pig house, the piglet body temperature, the power consumption of the heat lamp 7, the device running state, the standing and lying times of the sow and other information, and can also transmit the information to the cloud service platform 1, so that the breeder can realize intelligent control and remote monitoring of the pig house environment and the piglet growth environment through a terminal device.
