Embodiment 1

[0054] see figure 1 , figure 2 as well as image 3 , the present embodiment provides a livestock grazing sound signal acquisition device, which is used to collect the sound signals (biting, chewing, chewing-biting, rumination) sent by livestock 6 when grazing, for monitoring purposes . When the domestic animal 6 is grazing, it will emit different sound signals, and the time-frequency characteristics of each sound signal are different, and of course, their durations are also different. However, at the same time, there will also be environmental noises such as wind, walking, and machinery, as well as disturbing noises such as livestock calls and drinking water. Ambient and interfering noise can seriously reduce the signal-to-noise ratio of the acoustic signal. Therefore, collecting clean sound signals helps to improve monitoring efficiency, and can ensure the authenticity of collected data, and facilitate screening of these sounds. In this embodiment, the livestock and gra...

Embodiment 2

[0068] This embodiment provides a livestock grazing sound signal acquisition device, which adds a locator on the basis of Embodiment 1. The locator is fixed in the closed space, and it can locate the real-time position of the livestock 6 by GPS or Beidou satellite navigation system, and obtain a positioning information in real time. In this way, the remote monitoring platform can obtain the location of the livestock 6 in real time according to the positioning information, and associate each livestock with relevant information, such as sound information, serial number, etc., thereby generating a data database of the livestock 6 .

[0069] Moreover, the monitoring platform located at the remote end can update these information in real time, and when the sound of livestock 6 is abnormal, it can send an alarm message. On the one hand, it can remind the monitoring personnel in time to check whether the collection device is damaged or lost. On the other hand, it can monitor the lives...

Embodiment 3

[0071] see Figure 4 , the present embodiment provides a livestock grazing sound signal acquisition device, which increases the alarm 8 and the light strip 9 on the basis of the embodiment 1. The alarm 8 is arranged on the outside of the windproof and soundproof cotton 2, and can send an alarm signal. The control module judges whether the sound signal is abnormal. For example, when the sound signal of the livestock does not appear for one day or many days, the alarm 8 is driven to send an alarm signal; When the cry for help or the sound of fear, the alarm 8 is driven to send an alarm signal.

[0072] The band lamp 9 is arranged on the outside of the windproof and soundproof cotton 2, and it can be used as a sign at night, so that the monitoring personnel can find the domestic animal 6 accurately. Of course, in some embodiments, the strip lights 9 can be replaced by devices that are easy to attract attention in dark environments such as fluorescent strips, so that the monitor...

Abstract

The invention discloses a livestock feeding sound signal acquisition device and an acquisition method using the same. The device comprises a substrate, wind shielding and sound insulation cotton, a silica gel sleeve, a microphone, rebound foam and an interference noise elimination module. The substrate is attached to the surface of a livestock shearing forehead, and the wind shielding and sound insulation cotton is in a sucker shape, wraps the substrate and is fixed to the forehead. The silica gel sleeve comprises an inner layer, a sound insulation layer and an outer layer, the outer layer isattached and fixed to the wind-shielding sound-insulation cotton, and the sound-insulation layer is located between the outer layer and the inner layer. The inner layer, the substrate and a shearing surface form a closed space, and the microphone is arranged in the closed space and collects the sound signals of livestock. The rebound foam covers the microphone and extends to the inner layer afterexpansion, and the goat sound interference noise elimination module is used for eliminating interference noise. The device has the effects of weakening environmental noise and eliminating interferencenoise, minimizes the interference of environmental wind noise, the interference noise of sheep and other noise, and is easy to disassemble and replace, is small and exquisite, and is convenient to install.

Description

technical field [0001] The invention relates to a signal acquisition device in the technical field of animal husbandry, in particular to a livestock grazing sound signal acquisition device, and also to a livestock grazing sound signal acquisition method using the acquisition device. Background technique [0002] In my country's Inner Mongolia and Xinjiang and other regions, the animal husbandry industry occupies an important position, and grazing is the main way of animal husbandry. In order to pursue more economic interests, the herdsmen in the areas where the grazing prohibition policy has not been implemented blindly expand the number of livestock breeding, causing the imbalance of grass and livestock, and destroying the grassland environment. Although local livestock managers try their best to regulate grazing activities, they have been unable to effectively monitor grazing activities due to factors such as limited monitoring technology and low network coverage in pastor...
