Automatic counter of wild rodent activity frequency in grassland ecosystem

Abstract

The invention relates to an automatic counter for activity frequency of wild rats of a grassland ecosystem. The automatic counter comprises a box, wherein a power switch is arranged on one side of the box, and sounding windows I and II are arranged on the other side of the box; infrared detectors are arranged in the sounding windows I and II and are provided with USB (Universal Serial Bus) external interfaces; a power control panel, a timer, an electronic real-time counter, a current signal converter, a signal amplifier and a digital memory are arranged in the box respectively; the power control panel is provided with a power supply and a power indicator lamp respectively; the power supply is connected in series with the power switch, the infrared detectors I and II, the timer and the power indicator lamp, and is connected with the electronic real-time counter, the current signal converter, the signal amplifier, the USB external interfaces and the digital memory respectively; the infrared detectors I and II are connected with the electronic real-time counter through the signal amplifier and the current signal converter; the electronic real-time counter is hooked up with the USB external interfaces through the digital memory. The automatic counter is convenient, safe, real-time and accurate.

Description

technical field [0001] The invention relates to an automatic counter, in particular to an automatic counter for the activity frequency of rodents in the grassland ecosystem. Background technique [0002] Prairie rodent is a common animal hazard in grassland ecosystem. As an integral part of the grassland ecosystem, the existence of prairie rodents has a certain positive effect on the stability of the grassland ecosystem, especially through digging holes, storing food and grazing forages, the rodents can regulate the growth of grassland plant communities , Promote soil plowing, inhibit the spread of poisonous plants, promote the spread of plant seeds, etc. However, when the density of prairie rats is too high, it will lead to excessive feeding and consumption of grassland vegetation, which will sharply reduce the number of good pastures, expose the soil, and accelerate the degradation of grasslands. Therefore, it is a prerequisite to carry out rodent control to accurately g...

Problems solved by technology

Among them, poisoning rodents with poisonous bait often leads to the unintentional poisoning of many natural enemies or other non-target animals of rodents, causing great secondary damage to the grassland ecosystem.

When using methods such as mouse cages, sticky mouse boards, mouse traps, and powder tracks to monitor, after capturing mice or monitoring mouse tracks, it is impossible to know the specific time of capture or the specific time of mouse tracks. At the same time, the above monitoring devices are difficult to use. It is used to monitor the activity peak times and activity rules of diurnal rodents, especially the statistics of plateau pikas and Brandt's voles in alpine meadow grassland ecosystems, typical grassland ecosystems, desert grassland ecosystems and temperate grassland ecosystems Analyzing and measuring

When mouse traps and mouse cages are in use, they are easy to harm humans and livestock, and there are unsafe factors

The powder trail method and sticky mouse board are easily affected by wind and rain when used in the wild, and the results are inaccurate

Manually capturing rodents requires a lot of manpower and material resources, and the areas where a large number of rodents are active are mostly remote areas, where it is difficult for humans to enter and reach, and the cost of experiments is high, resulting in poor mouse-catching effect and inaccurate results.

[0004] Therefore, the main disadvantage of the above mouse catching method is that it will kill or damage the mice, thereby causing artificial damage or disturbance to the mice, resulting in inaccurate measured data.
