The monitoring sensor worn on the body of the livestock, the LoRaWAN positioning terminal worn on the body of the livestock and the main control chip are powered by the battery power supply module and charged through the solar cell panel.
The LoRa location technique enables "no other device dependent" location by using 3 or more Gateway to generate TDOA (Time Difference of arrival).
When the uplink data of a LoRaWAN terminal is received by three or more base stations, the LoRaWAN terminal can be located. These upstream data need not be location specific information and they may be in the normal LoRaWAN data frame structure. When multiple base stations receive the same uplink data at the same time, the location information of the terminal can be obtained by the multipoint positioning technology.
In fig. 2, the specific positioning steps are:
1, the LoRa terminal sends a data packet to each gateway node, and each gateway node uploads an uplink frame consisting of received data and a timestamp to a network server;
2, each received uplink frame will get the gateway accurate timestamp, which will be forwarded to the network server as part of the frame structure, including signal level, signal-to-noise ratio and frequency error;
the web server will order multiple receptions of the same data frame, group all metadata containing the data frame timestamp, and request a positioning calculation from the positioning solver. In a given frame structure, the basic positioning calculation function calculates the time difference between the reception of different base stations, and then the distance from the terminal equipment to different base stations can be calculated through the time difference. Once the TDOA of two base stations is known, the location of this terminal can be placed in a hyperbola. By calculating the time difference several times, the position information of the terminal can be presented on several hyperbolas, and finally the position of the terminal should be at the intersection of these hyperbolas. Thereby obtaining the specific position coordinates of the terminal;
and 4, checking positioning information, motion state, vital signs and other information on the server through a PC (personal computer) or mobile intelligent equipment of the management terminal, and processing data through the management terminal to display information such as animal motion tracks, community number and distribution.
The motion attitude sensor and the vital sign sensor respectively adopt an MPU-6050 sensor and an MAX30102 module, and the attached figures 4 and 5 are respectively a motion attitude sensor and a vital sign sensor principle wiring diagram.
