Description
Technical Field
The utility model belongs to the technical field of the facility is bred to beasts and birds, specifically be based on the full-automatic PID governing system of piglet temperature of a touch-sensitive screen.
Background
The physical function development of the newborn piglets is imperfect, the body temperature regulation capability is poor, the resistance to cold is low, in modern breeding, the body condition of the newborn piglets is poor due to selective breeding of the pigs with low backfat thickness, and the colostrum intake of the piglets and the later period lactation rate are reduced to finally cause death if effective heat preservation measures are not taken. The sows and the piglets in the delivery room are in the same piggery, the suitable temperature of the sows is 18-22 ℃, the temperature requirement of the piglets is about 32-25 ℃ from birth to weaning, the sows are afraid of heat, and the piglets are afraid of cold. If the whole delivery room is heated to ensure that the temperature of the whole shed in the delivery room meets the requirements of piglets, the heat stress of the sows and the reduction of the lactation amount can be caused. Therefore, the temperature of the whole shed of the delivery room needs to be maintained within the temperature range required by the sow, and local heating is needed for local areas of piglets. At present, in a newly-built large-scale pig farm delivery room (one unit sow has 45-72 heads) in China, a heat preservation lamp is generally used for heating or is combined with an electric heating pad or a floor heating for heating, the temperature of a heat preservation area of a suckling piglet is set at random, the heat preservation lamp is turned off too early in some pig farms or the power is reduced to a low value, so that the temperature of the heat preservation area cannot meet the requirement of the piglet, and the heat preservation lamp is kept to operate at constant power in some pig farms. Along with the increase of the day age of the piglets, the temperature demand of the piglets is gradually reduced, the temperature under the constant-power heat preservation lamp is higher than the piglet demand, the full-power operation of the heat preservation lamp wastes electric energy, and the redundant heat dissipation of the heat preservation lamp can increase the heat stress degree of the sows.

In addition, the frequent direct power on-off of the relay can damage the heat preservation lamp, and the service life of the heat preservation lamp is reduced. The intelligent piglet temperature control system with the Chinese patent number ZL205922389U utilizes a single chip microcomputer control mode developed by a user, the constant temperature effect is more stable than a relay control mode, but the system adopts a key keyboard mode to input parameters, and due to the fact that keys are mechanical contacts, the phenomena of poor contact, damage and the like easily occur after the system is affected with damp along with the lapse of time, the temperature cannot be controlled, the energy consumption is increased, and the scheme does not have an automatic dehumidification function in a humid environment and influences the stable operation of equipment.
In a delivery room (pigsty) of a large-scale pig farm, the artificial accurate adjustment of the temperature of a piglet area in each delivery fence along with the increase of the day age of the piglet is time-consuming, labor-consuming and difficult to realize. Therefore, the automatic temperature control method is urgently needed in a large-unit delivery room of a large-scale pig farm to automatically regulate and control the thermal environment of a local heating area of piglets according to the temperature requirements of the piglets, namely, the power output of the heat preservation lamp is gradually reduced along with the increase of the day age of the piglets so as to reduce the temperature under the heat preservation lamp, and the purposes of meeting the temperature requirements of the piglets and reducing the energy consumption are achieved.
