In the analysis of air sampling data, it is usually impossible to determine the specific air pollution conditions. Pollution originates from the impact and contribution caused during a specific time (usually only a few cuts). And 'Because often the wind direction changes (sea and land wind and local field hoisting) are too frequent in a day, if there are more than two pollution sources from different directions, it is difficult to judge the pollution status of the gas sampler where it is located. Caused by pollution sources, and even very likely to cause misjudgment of pollution source analysis. Therefore, it is necessary to provide an innovative and progressive air sampling system to solve the above problems. Summary of the invention i In detail, it is about a kind of standardization.

I, the air sampling system μ with automatic wind direction identification of the present invention includes a wind direction monitor 11, a plurality of air samplers 12, 13 ′, 14, 15, and a processor 16. The wind direction monitor η is used to detect the wind direction and obtain the actual wind direction angle. These air samplers 12, 13, 14, 15, etc. are used for sampling pollutants in the air. The processor 16 is configured to generate a control signal to enable or disable the air samplers 12, ίο, 14, 1 according to a preset wind direction range of degrees and compare with the actual wind direction angle of the wind direction monitor 11. 5 of the sampling. With reference to Figs. 1 and 2, the operation of the air sampling system 1 of the present invention will be described with a flowchart. First of all, the wind direction angle of the scheduled monitoring Fan Yuan ^ has: parameter settings such as numerical values are input to the processor 16, as shown in step 201, 〆 '', this real ____- 6- This paper size applies Chinese national standards (CNS ) Α4 size (210X 297 cm) 527488 A7

In the case of the "pre-testing", the wind direction angle range is set to 270 to $ 5 degrees (0 degrees from the north), and the wind direction data of the wind direction monitor is calculated based on the wind direction per second. The average wind direction value per minute, and the effective wind direction percentage range is cumulatively calculated every five minutes. When the effective wind direction percentage meets the wind direction angle range above 70%, start the air sampler.

As shown in step 202, the wind direction monitor 11 detects actual wind direction data. Referring to step 203 ′, the wind direction monitor η transmits the actual wind direction data to the data acquisition unit 17, and the data acquisition unit 17 records the actual wind direction data detected by the wind direction monitor 11 every minute. Referring to step 204, the data, the extractor 17 transmits the recorded wind direction data to the processor 16. Here, 2 and 16 are compared according to the preset wind direction angle range and other parameter setting data with the actual wind direction data, as shown in step 205. If the actual wind direction data is within the set parameter range, the processor 16 sends a control signal to the switch controllers 22, 23, 24, ^, etc. (refer to FIG. 1), as shown in step 206. The switch controllers 2 2, 2 3 2 4, 2 5 start the air samplers age 12, 13, 14, 15 according to the control signal, turn on the air sampler, and perform sampling of air pollutants, as in step 2 0 7 shown. Referring to step 208, if the actual wind direction data does not meet the set parameters, the processor 16 sends a control signal to the switch controller. The switch controllers 2 2, 2 3, 2 4, 2 5 turn off the 2 gas sampler 1 2, 1 3, 1 4, 1 5 according to the control signal to turn off the air sampler, as shown in step 2 0 9 Show. Referring to FIG. 3 ′ is a parameter setting screen of the 2 gas sampling system of the present invention. This paper size applies to China National Standard (CNS) Α4 specification (210X297)

In the embodiment of the present invention, the range of wind direction angles to be monitored is set to 270 ± 45 degrees (zero degrees from north). The wind direction data of the wind direction monitor " is an average of every minute calculated based on the wind direction acquired every second. Wind direction value, and the effective wind direction percentage range is cumulatively calculated every five minutes. When the effective wind direction percentage conforms to the wind direction angle Fanyuan reaches 70% &, the sampling of the air sampler is started. And ‘Effective wind direction Bai Nuo does not meet the wind direction angle range of more than 30%’ then close the air sampler. A reference is made to FIG. 4, where (wind direction data is a wind direction monitor)! The actual wind direction detected is recorded every minute—an average of numerical data. In addition, ““ TRUE ”indicates that the average wind direction in that minute meets a preset range of wind direction angle (2 70 ± 45 degrees), and "FALSEj" indicates that the average wind direction for that minute does not meet the preset wind direction angle range. For example: the wind direction from the first minute to the fifth minute (ιη14: 24) is within the preset The wind direction angle range Θ (27〇 ± 45 degrees), so they are all "TRUE"; and the wind direction at the sixth minute (14:25) is π degrees, which is not within the preset wind direction angle range, so it is "fa Lse ". According to the parameter setting of Fig. 3," Accumulate five strokes every five minutes "effective wind direction percentage range, the effective wind direction percentage accords with the wind direction angle range up to 70%. Start the sampling of the air sampler from the beginning, that is, if five minutes The actual wind direction data only needs more than four strokes (including four strokes, because the five minutes is 3.5 knives and 4 miles) within the preset wind direction angle range (that is, TRUE "), which meets the parameter setting range. In the examples The first minute to the fifth minute (14: 2〇 · ΐ4: 24). ≪ The wind direction is within the preset wind direction angle range, which are both 527488

“TRUE” ’therefore meets the set conditions, the air sampler status at the fifth minute (μ: 2) is“ ON ”, which means that the air sampler is activated and air sampling is performed at the sixth minute. The air sampler was activated from the fifth minute to the eleventh minute (M · · 30), and the state of the air sampler at the twelfth minute was "0ff", which means that the minute = twelfth minute (14 · · 27 · 14: 3ι) The actual wind direction does not meet the setting that the effective range of wind direction is more than 30% every five minutes, that is, in the eighth to twelfth minutes (14: 27-ΐ4 ·· Η) The condition of the pen is "FALSE" (more than 30% of five minutes is FALSE). Therefore, the air sampler will automatically turn off sampling at the 13th minute. Therefore, the air sampling system 1 of the present invention can perform automatic wind direction identification and air sampling synchronization operations for specific pollution sources, and analyze the air product analysis results and field instrument record data to effectively judge the impact of the pollution source on the environment and Contribution to pollution. 51 m In addition, the air sampling system of the present invention can perform long-time or shovel time wind direction identification and suspended particulate sampling operations, and even if it is controlled or sampled for a long time, there will be no misjudgment of the specific pollution source. ^^ The preset wind direction angle range, the cumulative calculation time (not limited to five minutes), and the effective wind direction percentage (not limited to 70%) can be adjusted according to actual conditions. The sampling wind direction setting range is 0 ~ 36 °. The air sampling system 1 of the present invention can be used for fixed-point sampling, and can also be provided with a plurality of air samplers located at different sampling locations to connect and control air sampling at different locations at the same time. For example, you can use ``, '', ~~ air to extract 527488
