Description

Technical Field

[0001] The present invention relates to the technical field of automated optical detection, and particularly to an automated detection device and a usage method based on a multi-source information coupled colorimetric sensor array. Background Art

[0002] Gas chromatography-mass spectrometry (GC-MS) is a common instrument for the qualitative and quantitative analysis of VOCs. However, its operation is cumbersome, time-consuming, and the results are lagging, making it difficult to meet the needs of large-scale rapid detection. With the progress of nanotechnology, materials science, and computer technology, colorimetric sensor array technology has gradually emerged as a new detection method. It uses the color change caused by chemical reactions as the detection signal and has been widely applied in various fields.

[0003] However, most of the existing colorimetric sensor array experiments are limited to laboratory conditions, and due to the influence of factors during the image acquisition process, the results are often unstable, making it difficult to achieve automated, rapid, and stable detection. In addition, traditional colorimetric sensors usually only obtain RGB color information and cannot comprehensively capture the detailed characteristics of volatile organic compounds, while spectral information can provide more abundant analysis data. Therefore, how to achieve a rapid reaction between volatile organic compounds and the colorimetric sensor array and combine the real-time analysis of RGB and spectral information has become a technical problem to be solved urgently. Therefore, it is of great practical significance to develop a non-destructive and rapid detection method to achieve the rapid detection of volatile organic compounds based on a digital evaluation method.

[0063] A method for realizing a colorimetric sensing array automatic detection device based on multi-source information coupling, using the device according to any one of claims 1 to 5, comprising the following steps:

[0064] Step 1: After turning on the power supply 703, the device starts to be powered on and preheated; the fixed sealing device 205 in the gas generation device 2 is opened upward through the sealing drive motor 201, and the solution of the volatile organic compound to be measured is placed in the heating bottle 206; the fixed sealing device 205 is closed downward, and the heating control module 208 sets the target temperature and starts to heat the prepared solution until the bottle is filled with volatile gas; subsequently, the nitrogen generator 303 is started, and nitrogen enters the reaction gas chamber 301 through the cleaning connection port 3013 to remove air.

[0065] Step 2: Install the colorimetric sensing array 410 on the sensor mounting bracket 408. After fixing, drive the stepping motor 401 to move the fixed table 407 horizontally; when passing through the hyperspectrometer 605, stop the motor to collect the spectral information of the colorimetric sensing array 410; continue to operate the motor, and when passing through the acquisition camera 505, collect the initial image information of the colorimetric sensing array 410.

[0066] Step 3: Drive the stepping motor 401 to continue to operate, and the sensor mounting bracket 408 carries the colorimetric sensing array 410 through the concave opening 3012 of the reaction gas chamber into the inner cavity 3011 of the reaction gas chamber; drive the stepping motor 401 to stop operating. At this time, the air valve 211 is opened, and the gas in the heating bottle 206 enters the inner cavity 3011 of the reaction gas chamber through the gas outlet pipe 210 and reacts with the colorimetric sensing array 410.

[0067] Step 4: The stepper motor 401 drives the fixed stage 407 to move horizontally. When passing by the hyperspectral spectrometer 605, the spectral information after the reaction of the colorimetric sensor array 410 is collected; then it continues to operate. When passing by the acquisition camera 505, the image information after the reaction is collected; finally, the fixed stage 407 returns to the initial position to complete the return operation of the colorimetric sensor array 410.

[0068] Step 5: The hyperspectral spectrometer 605 and the acquisition camera 505 transmit the initial and reaction spectral and image information of the colorimetric sensor array 410 to the edge computing processor 705; the edge computing processor 705 analyzes the data and visualizes the results on the control display 701.

[0069] During specific use, the working principle of the present invention is as follows:

[0070] When the power supply 703 is turned on, the entire device starts to be powered on and preheated to ensure that each component is in the best working state. At this time, the sealed drive motor 201 in the gas generating device 2 starts to work, and drives the lifting lead screw 213 to rotate through the rotation of its drive shaft. The lifting lead screw 213 performs a threaded sliding with the threaded slide 204, thereby driving the threaded slide 204 to move up and down. The two ends of the threaded slide 204 are slidably connected to the support slide rod 203 to ensure the stability of its up and down movement. A connecting rod 214 is provided at the bottom position in the middle of the threaded slide 204, and the connecting rod 214 is connected to the fixed sealing device 205. When the threaded slide 204 rises, the fixed sealing device 205 is driven to move upward through the connecting rod 214, thereby opening the bottle mouth of the heating bottle 206. At this time, the operator can place the volatile organic compound configuration solution to be measured in the heating bottle 206. Subsequently, the sealed drive motor 201 rotates in reverse, driving the threaded slide 204 to descend, and the fixed sealing device 205 also descends accordingly to perform a sealed docking with the bottle mouth of the heating bottle 206. The heating bottle 206 is placed on the heating table 207, and the heating table 207 is connected to the heating control module 208. After the heating control module 208 sets the target temperature, it starts to heat the configuration solution in the heating bottle 206 until the bottle is filled with volatile gas.

[0071] During the heating process or after the heating is completed, the nitrogen generator 303 is started, and nitrogen is generated and enters the reaction gas chamber 301 through the cleaning connection port 3013 to clean the reaction gas chamber 301 to remove the air therein and provide a pure environment for subsequent chemical reactions.

[0072] Next, install the colorimetric sensor array 410 on the sensor mounting bracket 408 and fix it in place. Then, drive the stepper motor 401 to start working. Through its driving effect, the fixed stage 407 moves horizontally. When the fixed stage 407, carrying the colorimetric sensor array 410, passes by the hyperspectral spectrometer 605, drive the stepper motor 401 to stop running, and the hyperspectral spectrometer 605 starts to collect spectral information of the colorimetric sensor array 410. After the spectral information collection is completed, drive the stepper motor 401 to continue running, and the fixed stage 407 continues to move. When it passes by the acquisition camera 505, the acquisition camera 505 starts to collect the initial image information of the colorimetric sensor array 410.

[0073] After the initial information collection is completed, drive the stepper motor 401 to continue running. The sensor mounting bracket 408 carries the colorimetric sensor array 410 and enters the inner cavity 3011 of the reaction chamber through the concave opening 3012 of the reaction gas chamber. At this time, drive the stepper motor 401 to stop running, and at the same time open the gas valve 211. The volatile gas in the heating flask 206 enters the inner cavity 3011 of the reaction gas chamber through the gas inlet pipe 212 and undergoes a chemical reaction with the colorimetric sensor array 410. After the reaction is completed, drive the stepper motor 401 to start again, driving the fixed stage 407 to move horizontally. When it passes by the hyperspectral spectrometer 605, the hyperspectral spectrometer 605 collects the spectral information of the colorimetric sensor array 410 after the reaction; then continue to run. When it passes by the acquisition camera 505, the acquisition camera 505 collects the image information of the colorimetric sensor array 410 after the reaction. Finally, the fixed stage 407 returns to the initial position to complete the return operation of the colorimetric sensor array 410.

[0074] During the whole process, the hyperspectral spectrometer 605 and the acquisition camera 505 transmit the initial and post-reaction spectral and image information of the colorimetric sensor array 410 to the edge computing processor 705. After receiving this information, the edge computing processor 705 starts to process and analyze it. It can process the data from the colorimetric sensor array 410, the image information acquisition system 5, and the spectral information acquisition system 6, perform multi-source information analysis, and then output the detection result. The detection result is visually displayed through the control display 701, and the operator can understand the relevant information of the volatile organic compounds to be detected by observing the result on the control display 701.
