In addition, the sensor unit 600 may be further provided. The sensor unit 600 automatically measures the odor and VOC content in the air flowing into the sample collection tube, and when the measured value deviates from the threshold, the control unit 400 Automatically control each valve to capture air.

Hereinafter, the operating state of the air odor and VOC sample unmanned automatic collection device 20 according to the present invention as described above will be described.

In order to maintain the vacuum state of each air room 110, 120, 130, the respective vacuum valves 111, 121, 131 are opened (ON) under the control of the control unit (ON), the closing valves 112, 122, 132 are closed (OFF), and each selection valve 113, 123, 133 is connected to each vacuum. Open to the pipe (111,121,131) side.

After the valve operation, the air pump 500 is operated under the command of the control unit 400 so that the air in each air room 110, 120, 130 is discharged to the air discharge pipe 510 so that the inside of each air room 110, 120, 130 becomes a vacuum. After that, the vacuum valves 111, 121 and 131 are controlled to close.

Such a state may be referred to as a standby state for collecting outside air, and the present invention is preceded by the following process in order to more accurately collect the atmosphere.

That is, under the control of the controller 400, the vacuum valves 111, 121, and 131 are closed, and the valves 112, 122, and 132 are opened to collect the air before the occurrence of the pollution situation in the first installed region, and the air pump After controlling the 500, the collected first air is discharged back to the atmosphere through the air discharge pipe 510, and then the managers can wash each of the collecting bags 210, 220, and 230, and then the actual pollution. Proceed with the air collection process.

This is because the degree of contamination varies from place to place, whereby the interior of the initial collection bag is cleaned with standard air from the installation area, the standard air is stored and set as the default value, and the contamination level of the collection bag is installed before installation. By removing it, accurate measurement is performed. In addition, the collecting bag may be accompanied by a foreign material, which is to wash the collecting bag to prevent the air being collected from being contaminated by the foreign material.

When the above process is completed, in order to collect the air next time, when the on-off valves 112, 122, and 132 are opened in the above standby state (ON), the outside air is collected through the sample collecting pipes (211, 221, 231) as shown in FIG. ) Is collected, and controls the closing valves 112, 122, and 132 to close when the collecting bag becomes cold or no longer occupies depending on the control time.

In order to collect the collected sample, the sampling paths 117, 127, and 137, which are bypass paths, are used, and the selector valves 113, 123, and 133 are closed in the state in which the shutoff valves 112, 122, 132 and the vacuum valves 111, 121, 131 are closed. By controlling the opening to the side and operating the air pump 500, the sample is bypassed to the sampling pipes 117, 127, 137 as shown in Figure 4 to move to the air discharge pipe 510 side to take the sample to be monitored.

In this case, when the collection is completed, residual vacuum may remain in the air rooms 110, 120, and 130, and a pressure control valve 114, 124, and 134 configured in each air room 110, 120, 130 is required to remove the residual vacuum. For example, if the vacuum remains in the air rooms 110, 120, and 130, the air pump 500 may be overloaded to collect the collected sample, and the air pump 500 may be broken or the sampling may not be performed properly. . In order to solve this problem, the pressure control valves 114, 124, 134 are opened to remove the vacuum of each air room 110, 120, 130 after the collection is completed, and the samples are collected after closing the pressure control valves 114, 124, 134.

The operation as described above can be controlled in various forms, such as being simultaneously collected in a plurality of collecting bags or being sequentially collected according to the contamination situation of the installed place.

For example, in order to collect only the first collecting bag 210, the above operation is performed only by the control of the first opening / closing valve 112, the first vacuum valve 111, and the first selection valve 113. The third valves may be left in the standby state, and the same may be achieved by only the second collecting bag 220 and the third collecting bag 230.

And, optionally, the collection of the first collection bag 210 is a specific time of the morning, the collection of the second collection bag 220 is a specific time of the afternoon, the collection of the third collection bag 230 to operate as described above in the evening specific time. You can set the time,

When the first contamination occurs, the first collecting bag 210 may be collected, and the second collecting bag 220 may be sequentially collected and the third collecting bag 230 may be collected at specific time intervals.

Since the unmanned automatic collecting device 20 according to the present invention is capable of collecting in a plurality of collecting bags, according to the contaminated area, the fourth and fifth collecting bags and necessary components are added, such as morning, afternoon, In the evening, each collection bag is collected, and when additional collection occurs, the fourth and fifth collection bags may be configured to be controlled to be controlled.

By performing such a complex function, various active responses can be made depending on the contaminated area, which enables quick and effective pollution prevention while reducing the waste of additional equipment, wasteful manpower and equipment.
