Because of the high requirements for current ripple 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 material of the protective cover plate must be 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 eaten by milk goats, and the RFID electromagnetic wave is easy to be absorbed by animal bodies, so that the protective cover plate is required to be embedded in the first acquisition module shell 5 to prevent hidden danger of production caused by false eating of the milk goats, the first antenna protective cover plate 3 is embedded in the first acquisition module shell 5, and the optimal distance between the first antenna protective cover plate 3 and the top plate of the first acquisition module shell 5 is 7cm, the nearest distance is 5cm and the farthest distance is 10 cm.
For the acquisition of diet drinking water information, sheep is an unconventional animal, and every diet and drinking water behavior have a setting, and the sliding rod can be touched regularly in the diet process, so that the aim of collecting data can be indirectly achieved by modifying the traditional sheep neck clamp. The feeding speed of the milk goats is stable, and the goats can eat or drink water every time the goats enter the goats neck clips, so that the food and drink water information of the milk goats can be indirectly measured in a software part through the opening and closing of the door magnetic switch 12, and the part is designed through a software algorithm.
As shown in fig. 3: the communication system structure comprises a Lora wireless controller, an RS485 wired controller and a total control node: the communication system adopts multi-level pyramid mode communication, a sheep house needs to be provided with a communication node to collect all data, the communication node can be connected with a plurality of collection nodes through the Lora communication protocol, each collection node is connected with 8 collection nodes through the RS485 protocol, and the overall topological structure is shown in figure 3. The collection node and the summarizing node are connected by a relatively stable wire, and meanwhile, wiring in the square steel pipe can be performed in advance in the factory production process, so that the trouble of on-site wiring is avoided. The summarizing node and the communication node are connected in a wireless mode, so that remote wiring and wiring can be avoided, meanwhile, as the summarizing node is used as a secondary node, the problem of disconnection caused by excessive wireless network connection is avoided, meanwhile, the summarizing equipment is used as an intermediate node to perform data transmission through a message queue in the design of a communication protocol, even if network disconnection is caused by unexpected accidents of a wireless network, the buffered messages can be continuously transmitted to the communication node after the network is recovered, and certain system redundancy is added.
The communication system structure comprises communication nodes, collecting nodes and collecting nodes, wherein a plurality of groups of arrays are combined to be used in actual production, the upper array is a first array, the lower array is a second array, the leftmost first data collecting unit of the first array is the communication node, the functions of the collecting nodes and the collecting nodes are combined, the leftmost first data collecting unit of the second array is the collecting node, the functions of the collecting nodes are combined, the other first array and the 7 data collecting units on the right side of the second array are the collecting nodes, the collecting nodes are connected with the collecting nodes through cables, the collecting nodes are connected with the communication nodes through wireless Lora communication protocols, and the distance connection mode is shown in fig. 3.

As shown in fig. 4: the communication system in the invention mainly comprises three states in the running process, namely a system initialization state, a time synchronization state and an acquisition state, and the time sequence relationship among the three states is shown in fig. 4:
in the system initialization state, the acquisition node and the summarizing node can send system initialization information to a unique communication node, and the communication node can return related configuration files to each node sending a request. Therefore, each time of unexpected power failure or unexpected program error can be ensured, the communication node can obtain error records and reconfigure information, and the collection and summarization nodes can be more conveniently modified and equipped at the communication node without changing a single node.
In the time initialization state, the system mainly relies on time measurement to indirectly measure the food and water intake, and time errors can be directly caused by the acquisition nodes in the long-time operation process of the acquisition nodes, so that the time synchronization is required periodically.
And acquiring a state, wherein all the transmissions in the state are asynchronous information transmissions, only the lower node transmits information to the upper node, and the upper node does not return information. After the acquisition node acquires data each time, immediately transmitting the data processed by the software algorithm under the condition of meeting the condition that two continuous messages are separated by 1 minute; after receiving the data, the summarizing node loads the data into a buffer queue, continuously reads the forefront data from the buffer data and sends the forefront data to the communication node, and the whole acquisition process is completed.
The working flow of the acquisition node is as follows:
1) The milk goat enters the groove position, an electromagnetic switch is opened, and the current TIME TIME1 is recorded:
2) Reading RFID information and corresponding temperature information once per second, and marking the RFID information and the corresponding temperature information as RFID and TEMP;
