Ear-installed livestock body temperature compound detection device

Abstract

The invention discloses an ear mounted type composite body temperature detection device for livestock. The ear mounted type composite body temperature detection device comprises a detector and an ear canal mounting device, wherein the detector comprises a central processor, a temperature sensor, a shell, a thrusting needle and a needle buckle matched with the thrusting needle; the central processor is mounted in the shell; the thrusting needle is mounted on the shell; the temperature sensor is connected with the central processor through a wire; in the ear canal mounting device, a gap is formed in the front section of the pipe wall of a sleeve; the front end of the sleeve is connected with a pressure cap; a tongue piece penetrates through the gap; two ends of a spiral spring are respectively in contact with the inner sections of the pressure cap and the tongue piece; a mandrel is arranged in the sleeve, and the front end of the mandril is in contact with the inner section of the tongue piece; the rear end of the mandrel is arranged outside the sleeve; an angle between the outer section and the inner section of the tongue piece is 95 to 150 degrees; the temperature sensor is arranged on the front side of the pressure cap. According to the ear mounted type composite body temperature detection device for livestock, the temperature sensor is mounted at the position, close to the eardrum, in the ear canal of the livestock, so that the livestock body temperature detection accuracy is obviously improved; furthermore, the ear mounted type composite body temperature detection device is mounted conveniently and stably and is favorable for application.

Description

technical field [0001] The invention relates to a livestock body temperature detection device, in particular to an ear-mounted livestock body temperature composite detection device. Background technique [0002] In the process of large-scale development of animal husbandry, the health of livestock is particularly important, which is directly related to whether the farm can develop normally. The health of livestock has an important relationship with its body temperature. Therefore, in the modern society where electronic technology is changing with each passing day, tracking and detecting the body temperature of livestock is an important means of monitoring the health status of livestock; It is convenient to install the detection device and other problems. [0003] Taking pig breeding as an example, during the period of estrus and epidemic disease, the body temperature change model of pigs is complex and subtle (such as: pulse, fluctuation, rise or fall, etc.). Through remote...

Problems solved by technology

[0007] The biggest problem with method 1 is that it is difficult to reflect the core body temperature of pigs by monitoring the body surface temperature with a remote infrared probe

The environment of the pig farm is harsh, and the body surface temperature of the pig is easily affected by the environment, such as changes in the ambient temperature of the pig farm, such as the pig's body surface is easy to attach feces, etc., so it is difficult to predict the core body temperature of the pig by the body surface temperature There is a lot of noise

Therefore, it is difficult to effectively predict the estrus period and disease of sows through changes in body temperature

[0008] Method 2 uses wearable devices to monitor the body temperature of pigs. However, the biggest problem for pig wearable applications is how to ensure that the wearable devices are fixed.

For example, CN205337201U is fixed by the neck temperature sensor, but the neck temperature sensor is large in size and easily wiped off by pigs and bitten off by each other, so it is not suitable for long-term wearing

In addition, the neck thermometer still only collects the body temperature of the pig's neck surface, and cannot reflect the core body temperature of the pig

For example, CN204654900U monitors the surface temperature of pigs through a patch-type temperature sensor, which has similar defects as CN205337201U: it is easy to fall off and the measurement is inaccurate

CN204888291U / CN101839773A / CN104396865A do not describe the sensor wearable device, therefore, it is impossible to judge the fixity of the sensor

In addition, the wifi protocol adopted by CN204888291U / CN101839773A and the zigbee communication protocol adopted by CN104396865A are difficult to achieve ultra-low power consumption standards, thus reducing battery life

The communication distance between zigbee and wifi is limited, and it is difficult to achieve long-distance transmission (>100m) transmission distance, so it is necessary to install multiple sets of receivers (AP) to receive relevant data or use mesh network to achieve

Mesh network also increases the power consumption of the sensor itself
