Miniature animal experiment phytotron and control method

Abstract

The invention provides a miniature animal experiment phytotron which comprises a box body and a circuit controller, wherein the box body is divided into an animal feeding area, a temperature-humidity controlling area and an isolating cavity. The miniature animal experiment phytotron is characterized in that a temperature sensor, a humidity sensor, a gas pressure sensor, a gas composition sensor, an illuminance sensor, a wind speed sensor and a lighting lamp are arranged in the animal feeding area; an electric heating tube, a humidifier and refrigerating equipment are arranged in the temperature-humidity controlling area; a microcontroller is connected with a control circuit of the electric heating tube and the humidifier through a solid-state relay, connected with a control circuit of the lighting lamp through a digital rheostat, and connected with an exhaust blower and a blast blower through an optical-isolating silicon controlled rectifier driving circuit. By adopting the miniature animal experiment phytotron, climate parameters comprising the temperature, the humidity, gas pressure, gas compositions, the illuminance and the wind speed in the feeding area can be measured and regulated, wherein the temperature can be regulated in the range of 0 DEG to 50 DEG, the humidity can be regulated in the range of 30 percent relative humidity (RH) to 90 percent RH and the wind speed can be regulated in the range of 0.5m / s to 5m / s, so as to overcome the defect of less or single parameter of an simulated environment of the prior phytotron.

Description

technical field [0001] The present invention relates to an artificial climate chamber for small animal experiments and a control method thereof, more specifically, to an artificial climate chamber for small animal experiments integrating temperature, humidity, illumination, wind speed, and air pressure detection and adjustment and its control method. Background technique [0002] Animal experiments are essential in the production and manufacture of drug vaccines. The environmental conditions to be achieved in animal experiments are more important. Many experiments have very high environmental requirements. For example, sometimes high temperature and high humidity environmental condition models are required (when the temperature is higher than 40 degrees Celsius, the humidity is higher than 70% RH at the same time, and the wind speed exceeds 1.5m / s); some experimental conditions , not only has strict requirements on temperature and humidity, but also has certain requirement...

Many experiments have very high environmental requirements. For example, sometimes high temperature and high humidity environmental condition models are required (when the temperature is higher than 40 degrees Celsius, the humidity is higher than 70% RH at the same time, and the wind speed exceeds 1.5m / s); some experimental conditions , not only has strict requirements on temperature and humidity, but also has certain requirements on air pressure, illuminance and air pollutants in the experimental environment; for the above experiments, it is difficult for ordinary experimental facilities (instruments and equipment) to meet the required experimental requirements. will not be able to
