AI Technical Summary

Technical Problem

When using multi-cabin metabolic cabins to detect animal metabolism data, the instability of the gas environment inside the cabin and the drift of the gas analyzer sensors affect the accuracy of the detection results.

Method used

A multi-cabin multiplexed animal breathing heat measurement and metabolic analysis system was designed. The buffer vacant capsule designed with an arc-shaped shunt plate is used to stabilize gas input, and the sensor of the concentration analyzer is flushed and corrected through standard gas to ensure the stability of the gas environment and the accuracy of the detection data.

Benefits of technology

Through the design of arc-shaped shunt plates and standard gas correction, the problems of uneven gas distribution and sensor drift within the metabolic living compartment are reduced, and the accuracy and stability of metabolic data detection are improved.

Abstract

The present invention discloses a multi-cabin multiplexed animal respiration thermometry metabolic analysis system and a detection method in the field of metabolic cabin technology, comprising a metabolic cabin control group and multiple metabolic living cabins. An equipment cabinet is arranged inside the metabolic cabin control group, and detection pipelines for collecting gas and gas transmission pipelines for conveying gas are respectively arranged between the equipment cabinet and the multiple metabolic living cabins. A buffer empty cabin for conveying gas buffer is arranged on the inner rear side of each metabolic living cabin, and the buffer empty cabin is connected to the gas transmission end of the gas transmission pipeline, an exhaust solenoid valve is installed between two adjacent detection pipelines, and an intake solenoid valve is installed between two adjacent gas transmission pipelines. The present invention utilizes the buffer empty cabin to ensure the stability of the gas entering the metabolic living cabin, and flushes and corrects the sensor inside the concentration analyzer with standard gas, thereby reducing the accuracy of the detection data affected by the internal drift of the sensor inside the concentration analyzer.
