[Abstract]:[objective] at present, the government's supervision of live pigs remains on the passive supervision of label labels. However, due to the delay in supervision, malignant incidents often occur in which dead pigs are discarded. In order to solve the problem of remote supervision of live pigs by regulatory authorities, At the same time, it is convenient for breeding enterprises to monitor the heart rate of live pigs and take effective measures in time for pigs with abnormal heart rate. This paper designs a remote monitoring system for collecting heart rate and judging the survival of live pigs. [methods] the system adopts the data transmission mode of wireless sensor network, which is composed of intelligent ear mark, routing node, gateway, remote server, etc. Pig farm monitoring center, government regulatory monitoring center composition. The intelligent ear mark collects data through the wireless Zig Bee network through the routing node, and the GPRS module in the gateway forwards the data to the remote server via Internet. The software system automatically alerts the abnormal pig data. Referring to the design of wearable heart rate monitoring for human, the heart rate sensor is designed by using photoelectric heart rate measurement method, using LED and light sensor, combining with filter circuit and amplifying circuit. At the same time, in order to determine the luminous wavelength of LED and the inductive wavelength of light sensor, blood samples were collected from the ears of pigs with different weights, and Langby's law was used. Based on the spectral absorbance law of Hb O 2 and deoxyhemoglobin (Hb), the causes of inaccurate measurement of heart rate sensor in moving state were analyzed based on the principle of photoelectric heart rate measurement. In addition, using the DMP (Digital Motion Processor) of attitude sensor MPU6050 to obtain stable posture data, and recognizing the inaccurate data collected by heart rate sensor. Finally, CC2530 with Zig Bee protocol is used to realize heart rate sensor and MPU6050 data reading by using ADC converter, I / O analog IIC protocol, and data transmission through Zig Bee network. The power consumption is reduced by using its PM2 (sleep) mode. An ear label which integrates heart rate and attitude monitoring was made to wear on pig ear. [results] the study showed that the spectral absorbance law was observed from Hb O 2 and Hb, taking into account the cost of electronic components, the universal rate, and the influence factors on the life of live pigs, etc. The effect of nm light on measuring the heart rate of live pigs is obvious. Compared with the traditional manual measurement method, the heart rate error of live pig heart rate sensor was 0.9, because the sleeping time of live pig was more than 75% and it was only active before and after eating. Therefore, heart rate sensor can monitor live pigs for a long time, especially using MPU6050 to monitor movement, so the system can monitor heart rate in static state and attitude monitoring in dynamic state. [conclusion] because the ear label is light in weight, small in volume, low in power consumption and accurate in measurement, it is convenient to monitor heart rate and posture of live pigs under static condition. Not only live pig survival state monitoring, but also the long-term monitoring of live pig heart rate. The passive monitoring mode of traditional RFID ear label is changed, which is of great significance to improve the welfare level of live pigs and enhance the government's supervision ability.
