Application of Livestock Positioning System Using Radio Frequency Identification and UAV Technology

Driven by factors such as continuous population growth, accelerated urbanization, and increased income, the consumption of aquaculture products in China has grown rapidly, and the aquaculture industry in China has been in a period of rapid development for a long period of time. The rapid and healthy development of the aquaculture industry is conducive to promoting the adjustment and optimization of the internal structure of agriculture, expanding new channels for agricultural economic growth, increasing farmers' employment opportunities and increasing farmers' income, and gradually forming a virtuous circle between agriculture and industry. Animal husbandry occupies a large proportion in the breeding industry. Animal husbandry is mainly divided into captive breeding and free-range breeding. Among them, free-range livestock have good meat quality and can meet people's requirements for meat taste and nutrition; at the same time, free-range livestock are expensive and can Further increase the income of farmers.

However, due to the vast rural areas in China, especially the topography in the south, free-range farmers in mountainous and hilly areas will face the following problems:

1) It is difficult to locate livestock. In areas with large spatial area and complex terrain, it is difficult to obtain the specific location of livestock.

2) Livestock are easily lost. It is easy to be stolen or lost by yourself.

3) It is difficult to count the number of livestock. It is difficult for breeders to count the specific number of livestock. Aiming at the pain points of free-range livestock, this paper focuses on the automatic cruise of drones

Path planning algorithm, data transmission protocol, and data preprocessing algorithm. A livestock positioning system based on RFID and UAV is designed. It is easy to use and has good applicability. It can reduce the difficulty of free-range management and reduce the loss of farmers.

1 System Overall Scheme

1.1 System scheme design

The livestock positioning system based on RFID and UAV is divided into three functional modules: data acquisition, data analysis and processing, and data display. The system combination utilizes active RFID equipment, unmanned aerial vehicle and mobile Internet technology to solve the problem of strong battery life, small size and low cost in the process of grazing livestock positioning.

The basic principle of the system is to use RFID to transmit radio frequency signals within a range of more than 100 meters, and the UAV with RFID Card reader and mobile phone will automatically cruise within the stocking range. The RFID data and signal strength are transmitted to a smartphone through Bluetooth, and the mobile phone obtains the geographic location at this time, and after data preprocessing, the data is transmitted to the system server through the mobile data network. The server side processes and analyzes the collected location and RFID data. The mobile client App can view the latest location data of livestock, which is convenient for farmers to manage livestock.
