The door magnetic switch 12 acquires the action switching value RFID antenna of the neck clamp to acquire the RFID number of the milk goat and the current body temperature of the milk goat. Because the requirement on current ripples is higher in RFID acquisition, the power circuit board module 1 and the control circuit board module 2 must be isolated, and electromagnetic interference cannot be easily generated on the same substrate.
Electromagnetic waves emitted by the RFID antenna cannot penetrate through metal, so that the protective cover plate is made of plastic, and the size of the metal cover plate and the size of the antenna must be strictly controlled. However, the plastic product is easy to be gnawed by the dairy goat, and the RFID electromagnetic wave is easy to be absorbed by the animal body, so that the protective cover plate is embedded in the first acquisition module shell 5 to prevent the production safety hidden trouble caused by the accidental feeding of the dairy goat, the first antenna protective cover plate 3 is embedded in the first acquisition module shell 5, the optimal distance from the first antenna protective cover plate 3 to the top plate of the first acquisition module shell 5 is 7cm, the closest distance is 5cm, the farthest distance is 10cm, and the optimal distance is 7 cm.
To the acquisition of diet drinking water information, the sheep is a very regular animal, all has a situation in every diet and drinking water action, and the touching slide bar that can be regular among the diet process, therefore through the transformation to traditional sheep neck clamp, the purpose of reaching the data acquisition that can be indirect. Usually, the feeding speed of the dairy goat is stable, the dairy goat is fed or drunk every time when the dairy goat enters the neck clamp, the feeding and drinking information of the dairy goat can be indirectly measured through the opening and closing of the door magnetic switch 12 in the software part, and the part is designed through a software algorithm.
As shown in fig. 3: the communication system structure comprises a Nora wireless controller, an RS485 wired controller and a master control node: the communication system adopts a multi-level pyramid mode for communication, one sheepfold needs to be provided with one communication node for summarizing all data, one communication node can be connected with a plurality of summarizing nodes through a Nora communication protocol, each summarizing node is connected with 8 collecting nodes through an RS485 protocol, and the overall topological structure is as shown in figure 3.
