Embodiment 1

[0037] The track inspection trolley detects the respiratory rate

[0038] There is a fixed installation track above the pigsty stalls, and the trolley patrols different stalls in the pigsty through the rails, burns the algorithm into the millimeter wave radar module, and deploys the millimeter wave radar on the trolley; the trolley patrols every time It will stay in each pen for 3 minutes, and then through these three minutes, the millimeter-wave radar will collect the respiratory data of the pigs below, and then the data will be calculated by the algorithm in the module to obtain the respiratory rate, and the respiratory rate will be transmitted to the pig through the serial port Background, the specific test data are as follows:

[0039]

Embodiment 2

[0041] The ground inspection trolley detects the respiratory rate

[0042] The ground car patrols different stalls in the pigsty through the road, burns the algorithm into the millimeter-wave radar module, and deploys the millimeter-wave radar on the car; each patrol will stay in each stall for 3 minutes, Then, after these three minutes, the millimeter-wave radar will collect the breathing data of the side pigs, and then the data will be calculated by the algorithm in the module to obtain the breathing frequency, and the breathing frequency will be transmitted to the background through the serial port. The specific test data is as follows:

[0043]

Embodiment 3

[0045] Mobile phone to detect respiratory rate

[0046] The mobile phone is connected to the radar module, open the respiratory frequency detection app through the mobile phone, and align the display in the app with the pig to be detected. After obtaining the breathing data of the pig for 1 minute, the mobile app will display the current respiratory frequency product detection index of the pig ( According to GB20287-2006), the specific test data are as follows:

Abstract

The invention designs a radar-based non-contact respiration detection method for pigs. A millimeter wave radar is creatively applied to respiration detection for pigs, and a depth camera detection in the prior art is replaced. A respiratory rate and a heart rate of pigs are calculated through steps of data collection, data preprocessing, signal separation, mobile noise pollution judgment and processing, respiratory rate calculation, harmonic wave removal and the like, whether heartbeat harmonic waves are overlapped with the respiratory rate or not is judged according to the calculated respiratory rate and the calculated heart rate, and if the overlapping exists, a designed filter needs to be used for filtering out heartbeat harmonic waves in breathing data and recalculating the respiratory rate. In conclusion, the non-contact respiratory rate monitoring method solves problems that the cost is high and the precision is relatively low when the respiratory rate of the pigs is detected through a depth camera. Meanwhile, accuracy of an final respiratory rate result is further improved through cooperation of a multiple spectrum estimation method, a mobile noise removal and a heart rate filter method.

Description

technical field [0001] The invention relates to the technical field of intelligent detection of physiological characteristics of livestock and poultry, in particular to a radar-based non-contact pig breath detection method. Background technique [0002] In recent years, with the rapid development of intelligent pig raising, the development of detection of pig physiological characteristics has attracted more and more interest of those skilled in the art, and respiratory rate is an important reference data for judging the health status of pig vital signs, not only can be used To detect the current state and health of the pigs, and it can also detect pigs with abnormal respiratory rate for early warning, such as early warning for pigs with rapid respiratory rate, and notify the breeder to take care of the pigs. [0003] At present, the existing technical field adopts the method of detecting the respiratory rate of pigs based on the depth camera. The general steps are: first, th...
