At present, the most commonly used device for detecting carbon dioxide concentration on the market is a carbon dioxide detector, which converts the carbon dioxide concentration signal in the environment received by the carbon dioxide probe into a digital signal and outputs it to the display screen. Carbon dioxide detectors are often used in mushroom houses in the edible fungus industry, but there are many shortcomings. First, due to the high humidity working environment of the edible fungus fruiting room, water vapor in the air easily condenses on the surface of the carbon dioxide probe to form water droplets or water film, blocking the transmission of infrared light and affecting the measurement accuracy and stability of the probe; secondly, in a high humidity environment, the carbon dioxide probe may react chemically with water vapor, resulting in corrosion or oxidation of the probe material, thereby damaging the structure and performance of the probe and affecting the life of the probe; in addition, in order to detect the environmental data in the edible fungus fruiting room at any time, a carbon dioxide detector needs to be configured in each room, which greatly increases the initial investment cost and operation and maintenance cost. In terms of carbon dioxide control, personnel are required to manually turn on and off the ventilation equipment.

[0033] In order to facilitate air extraction, in this embodiment, a hollow air extraction portion 21 is provided on the air collection box 2, and multiple air pipes 6 are connected to one end of the air extraction portion 21, and the other end of the air extraction portion 21 is connected to the air inlet of the air extraction device 4; wherein the air extraction device 4 is an air pump. In this way, the air pipes 6 can be arranged regularly, making the structure of the detection cabinet 1 beautiful and compact; and this method can prevent the air from other air pipes 6 from polluting the internal space of the air collection box 2, thereby improving the accuracy of the detection cabinet 1.

[0034] In this embodiment, the gas collecting box 2 and the detection cabinet 1 are both made of stainless steel, so that they can have a longer service life in an environment of high temperature, high humidity and high carbon dioxide concentration.

[0038] In this embodiment, the detection cabinet 1 is installed on the outer wall of one of the mushroom houses 10 , and a display screen 9 capable of displaying the carbon dioxide concentration of each mushroom house 10 is provided on the detection cabinet 1 .

[0039] In this embodiment, the fresh air system 101 includes a fresh air fan, and the exhaust system 102 includes a positive pressure exhaust valve. The fresh air fan and the positive pressure exhaust valve are installed on the mushroom house 10. The fresh air fan can draw outside air and replenish it into the mushroom house 10, and the air in the mushroom house 10 can be discharged from the exhaust valve. Specifically, a terminal device of a refrigeration system is installed at a top position on one side of the edible mushroom house 10, and a suitable axial flow fan or a centrifugal fan is selected as the fresh air fan according to the air volume and air pressure required by the mushroom house 10. The power supply of the fresh air fan is connected to the detection cabinet 1, and the start and stop of the fresh air fan is controlled by the detection cabinet 1; the fresh air fan is installed at a top position on one side of the edible mushroom house 10, and this position is often close to the side of the terminal device of the refrigeration system, so as to cool down the fresh air in time; the positive pressure exhaust vent is a rectangular hole opened on the mushroom house 10, and the size of the hole is positively correlated with the air volume of the fresh air fan.

Among them, in the automatic control mode, if the difference between the actual measured value and the set value is too large, the detection cabinet 1 will send an opening signal to the fresh air fan contactor according to the preset value, and the system will turn on the fresh air fan configured in the corresponding mushroom room 10. With the opening of the fresh air system 101, the carbon dioxide concentration in the mushroom room 10 will gradually decrease and reach the preset concentration. At this time, the carbon dioxide detection cabinet 1 receives the relevant signal by detecting the concentration in the stable section, and sends a closing signal to the fresh air fan again. During the opening process of the fresh air fan, the positive pressure of the air in the closed mushroom room 10 is too large, and the exhaust gas will be automatically discharged through the positive pressure exhaust valve installed at the other end of the mushroom room 10, thereby realizing the automatic replacement of the room air and accurately controlling the carbon dioxide concentration in the room.
