Air pollution is caused by the presence or absence of one or more of the pollutants that are artificially released into the atmosphere, causing the amount, concentration and duration of the pollutants to be offensive to an unspecified majority in the area, or to endanger the public health of the area. Means a condition that harms the activities of animals and plants.

The substances causing air pollution are largely classified into gaseous substances, particulate matter, heavy metal substances and odorous substances. Gaseous substances include carbon monoxide, ammonia, hydrogen sulfide, carbon dioxide, and ozone, and particulate matter includes dust, soot, ash, fog, soot, aerosols, fumes, droplets, mists, swallowing, and allergens. Heavy metals are mercury. , Cadmium, lead, chromium, copper, nickel, vanadium, radioactive substances and the like, and odorous substances are very diverse, such as ammonia, methyl mercaptan, hydrogen sulfide, methyl sulfide, methyl disulfide, trimethylamine, astaldehyde, styrene and the like.

Conventionally, there have been techniques to remotely manage and measure the air pollutant emission situation in a specific region as described above. Conventional techniques, however, measure air pollutant emissions from a meter and transmit data to the user in one direction only, either via wired or mobile communications, and the meter is wired or connected to a code division multiple access (CDMA) device.

However, this conventional technique uses a fixed ubiquitous sensor network for measuring air pollution. The fixed ubiquitous sensor network is mainly installed on a building in a region with excellent vegetation environment, so it is an air pollution source and at the periphery of roads with severe air pollution. By not reflecting the status information, there is a problem that there is a limit in monitoring the air quality condition throughout the city.

In addition, the conventional technology has to be installed in all areas to measure air pollution fixed stationary ubiquitous sensor network, there is a disadvantage that increases the installation cost.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram of an atmospheric environment measurement system using a mobile ubiquitous sensor network according to the present invention.

As shown in FIG. 1, the atmospheric environment measurement system using the mobile ubiquitous sensor network according to the present invention is mounted on a moving object (vehicle, etc.) and is a portable atmospheric environment measurement device for measuring an atmospheric environment of a corresponding area on a movement path ( 100) and the air environment information measured by the mobile air environment measurement apparatus 100, the air environment information is displayed as shown in FIG. 2, and the air environment information is provided in response to a request from a subscriber station. Atmospheric environment information providing server to include.

Here, the mobile air environment measurement apparatus 100 communicates with the air environment information providing server 200 through HSDPA (High Speed Downlink Packet Access), WiBro, etc., the air environment information providing server 200 is WiBro, or HSDPA Provides atmospheric environment information to a subscriber station via a wireless LAN, or the like.

In addition, the mobile air environment measuring apparatus 100 may be mounted on a bus, a train and a taxi moving a certain area periodically as well as a specific vehicle for measuring the air environment, and may measure the air environment.

In addition, the air environment information providing server 200 stores the air environment information received from the mobile air environment measurement apparatus 100 as a database.

Hereinafter, the mobile air environment measurement apparatus 100 will be described in detail.

The mobile air environment measuring device 100 is ozone (O ₃ ), fine dust (PM10), sulfur dioxide (SO ₂ ), carbon monoxide (CO) as well as temperature, humidity, illumination, ultraviolet (UV), as well as atmospheric environmental evaluation factors ), A sensor 110 for generating atmospheric environment information by measuring nitrogen dioxide (N0 ₂ ), an external camera 120 for generating an atmospheric environment image by photographing a visible atmospheric environment on a moving path, and obtaining current location information. Atmospheric environment information measured by the GPS 130, the sensor 110 and the actual location image acquired by the GPS 130 and the actual location image taken by the internal and external cameras 120 and 150 It includes a gateway 140 for transmitting to the providing server 200, and an internal camera 150 for taking an image of the inside of the vehicle.

Here, the mobile atmospheric environment measuring apparatus 100 stores a database for storing the atmospheric environment information measured by the sensor 110 and the atmospheric environment image generated by the external camera 120 as a database (not shown in the drawing). ) May be further provided.

In addition, internal and external cameras 120 and 150 are additional elements of the present invention.

In addition, the sensor 110 communicates with the gateway 140 via short-range wireless communication or wired, such as ZIGBEE.

In addition, the sensor 110 has a structure arranged as shown in Figure 4, the external camera 120 has a structure capable of rotating 360 degrees, as shown in FIG. In this case, since the sensor 110 is mounted on the moving body and is not fixed at one position, the sensor 110 increases the accuracy of the measured value in consideration of the air inflow speed, rainfall, vibration, and the like.

In addition, the performance of the sensor 110 is shown in Table 1 below as an example.

Meanwhile, the gateway 140 drives the external camera 120 only when at least one measured value of the atmospheric environment measured by the sensor 110 exceeds a corresponding air pollution threshold, and displays the actual image at that time. The photographing may be transmitted to the atmospheric environment information providing server 200.

For example, when the fine dust measurement value exceeds the threshold due to yellow dust generated in China, the live environment image is transmitted to the atmospheric environment information providing server 200 by driving the external camera 120 to transmit the atmospheric environment information. Allow the subscriber to assess the seriousness of the yellow dust.

As another example, when the atmospheric environment measurement value suddenly increases on the movement route, the external camera 120 is driven to photograph the smoke emission situation of the surrounding vehicles (number plate photographing) to provide the atmospheric environment information server 200 or the atmospheric environment monitoring country. By providing an agency or the like to restrict the operation of the vehicle, it can help improve the atmospheric environment.

This will be described in detail with reference to FIGS. 6 and 7.

As shown in Figure 6, as a result of measuring the fine dust while moving the residential complex Ilsan single housing complex, it can be seen that the threshold (about 110 ㎍ / ㎥) does not exceed. However, as shown in FIG. 7, the measurement area is changed, and as a result of measuring fine dust in a bus-only lane or traffic jam area, it can be seen that the threshold is exceeded. In this case, the external camera 120 is driven to capture an image of a corresponding region.

As a result, it can be seen that the air pollution source is a bus and common smoke comes out of the bus. In fact, in addition to fine dust, other measurements also exceed the threshold.

Meanwhile, the external camera 120 may be always driven to perform the functions shown in the above example.

In addition, the live image captured by the external camera 120 on the movement route may be used as traffic information.
