step one, dividing the detection cabin 1 into a single detection cabinet 13, two detection cabinets 13 or a plurality of detection cabinets 13 according to the monitored indexes and the number monitored at the same time; each detection cabinet 13 is independently formed into a bin and is correspondingly provided with a respective bin door; each detection cabinet 13 is internally provided with a sensor, a fan and a temperature control device, and a tail interface for the sensor is arranged on the back of the detection cabin 1.

Step two, assembling the control boxes 2, selecting the corresponding control boxes 2 according to the number of the detection cabinets 13, installing branch valve boxes 24 in the control boxes 2, wherein each branch valve box 24 is provided with a control valve corresponding to each detection cabinet 13; a branch control box 25 for controlling branch indexes, wind control and temperature control is arranged below the branch valve box 24 inside the control box 2, and the control indexes corresponding to each control valve are connected one by one; the upper part of the detection cabinet 13 is provided with each detection cabinet 13 and a data display and storage device corresponding to the index.

In addition, in the using process, at least one air valve 6 is arranged on each sealed door of the detection cabinet (13), and the opening part of each air valve 6 is sealed by a detachable air cap; the air valve 6 is connected with the wind control device in a combined mode, when the indoor air environment quality is monitored, outdoor air enters through the fact that the pressure intensity is reduced through air circulation in the detection cabinet (13), and the indoor air monitoring and detection with equal frequency are conducted through the time-sharing switch.

Thirdly, mounting a fastener 5 on the side wall where the detection cabin 1 and the control box 2 are correspondingly connected in advance, moving the detection cabin 1 and the control box 2 to a place to be monitored for buckling, and fixing the universal wheel 3 at the bottom; and (3) connecting the control lines of indexes, wind control and temperature control of each part in the control box 2 with the interfaces of the detection cabin 1, and connecting the control lines after the debugging test is qualified.

And step four, wiping each detection cabinet 13 with distilled water before testing, carrying out labor intensity cultivation at the temperature of 22.5-23.5 ℃, humidity of 47% -53%, ventilation quantity of 0.95-1.05 times/h, background concentration of TVOC < 0.3mg/m, and formaldehyde < 0.05mg/m, and ventilating for at least 1 hour.

In the embodiment, the air exchange rate in the detection cabinet 13 is 0.2-2.0 times/hour, and the deviation is +/-5%; the central wind speed can be adjusted to 0.1-1.0 m/s; the sealing performance is the air supply rate with the air leakage rate less than 5 percent; the recovery rate of the equipment is more than 80 percent, and the relative positive pressure is kept at 10 +/-5 Pa.

And step five, starting the control box 2, and detecting the background value of each detection cabinet 13 on line after each detection cabinet 13 reaches the preset test condition.

Sixthly, vertically placing the sample pieces at the center of an automatically controlled detection cabinet 13, wherein when a plurality of sample pieces are arranged in one detection cabinet 13, the distance between the sample pieces is not less than 200mm, and ensuring that air flow passes through the surface of the sample; the temperature and the humidity in the detection cabinet 13 are controlled to reach the actual or design standard.

Seventhly, the test period of the sample piece is not less than 96h, online detection and recording are carried out by using a data display and storage device, the initial data recording time is not more than 4h, and the material test period is recorded for not less than 7 times; selecting t =1h, 2h, 4h, 8h, 12h, 24h, 36h, 48h, 72h and 96h according to the test, recording data, and increasing monitoring points as appropriate;

and step eight, calculating and obtaining relevant parameters of the harmful substances of the materials, such as pollutant release amount, emission rate, pollution characteristic parameters and the like according to concentration results of all detected and monitored indexes, and displaying and carrying out staged early warning evaluation.

In addition, the control of the control box 2 in the multifunctional detection cabin can be integrated and modularized, and is divided into an online detection module, an air supply module, a purification system module, a temperature control system module, a humidity control system module, an air speed control system module, a cabin pressure system module and an early warning module, and one-key automatic operation is carried out through a PLC and HMI automatic control system. The on-line detection module comprises an electrochemical formaldehyde sensor, a TVOC sensor, an ammonia gas sensor, a benzene and xylene detection module which are a benzene sensor and a radon gas sensor, and the joints of the sensors are connected with the reserved interfaces of the detection cabinet 13. The intelligent monitoring system further comprises a remote monitoring module, wherein the remote monitoring module comprises an intelligent display screen 23, a router, a remote control system and a display screen 23.

The detection cabin 1 system is used for green and healthy decoration, wherein decoration and decoration materials are artificial boards and products thereof, bonded wood structural materials, wallhanging, curtains, soft package samples, carpets and liners thereof, wallpaper, veneer boards, block boards, density boards, glues and the like, and intelligent online monitoring of detection of harmful gases such as formaldehyde, TVOC, ammonia, benzene, xylene, radon and the like can be realized.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that may be made by those skilled in the art within the technical scope of the present invention will be covered by the scope of the present invention.
