System and method for monitoring body temperature of dairy cow in real time

Abstract

The invention provides a system and a method for monitoring the body temperature of a dairy cow in real time. According to the invention, a PT 1000 platinum resistance is used as a temperature measuring probe for acquiring the body temperature data of the dairy cow, and electric pressure generated by two ends of the PT 1000 platinum resistance are transmitted to a temperature treatment platform through an analog-digital converter, wherein the process of temperature acquisition is as follows: implanting a temperature sensor into the vagina of the dairy cow, and allowing the temperature measuring probe to contact with the vagina of the dairy cow, wherein the whole circuit module connected with the probe comprises a constant current source, the analog-digital converter, MCU and a wireless communication module; and the temperature information measured by the temperature sensor realizes wireless communication with a computer of a user through an STM32 microcontroller, so the temperature ofthe interior of the vagina of the dairy cow is finally displayed on the computer. The invention has the following advantages: the true body temperature of the dairy cow can be measured; meanwhile, themonitoring of the temperature information is realized; the body temperature information of the dairy cow is accurately monitored in real time; and simple structure, convenient operation and low priceare achieved.

Description

technical field [0001] The invention belongs to the technical field of modern breeding industry, relates to constant current source technology, temperature sensor technology, analog-to-digital converter technology, and wireless communication technology, and particularly relates to a system and method for real-time monitoring of body temperature of dairy cows. Background technique [0002] At present, the body temperature measurement of dairy cows at home and abroad mainly relies on manual measurement and manual recording, which is not only time-consuming and laborious, but also has low accuracy. At the same time, it is impossible to monitor the body temperature of cows in real time, and the accuracy of temperature measurement results is greatly reduced. .

Problems solved by technology

[0003] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a real-time monitoring system and method for cow body temperature, which can monitor the real body temperature of cows in real time, using PT1000 as the temperature sensor probe, the sensor is placed in the vagina of the cow, wireless sensor The antenna is placed outside the body of the cow to strengthen the wireless communication signal. The two ends of the PT1000 platinum resistance generate a temperature-related voltage value. The transmission module is sent to the user's host computer, and the temperature value of the cow's vagina is displayed on the user's computer to realize real-time monitoring of the cow's body temperature information, thereby getting rid of the traditional manual measurement and manual recording methods, and overcoming the existing low efficiency and low precision. High problems, real-time and accurate monitoring of cow body temperature information, its structure is simple, high degree of automation, easy to use and real-time, etc.
