Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It is to be understood, however, that the embodiments described below are only for explanation of the embodiments of the present invention so that those skilled in the art can easily carry out the invention, It does not mean anything.

FIG. 1 is a view for explaining a system configuration to which an apparatus for measuring air pollution degree according to an embodiment of the present invention is applied. Referring to FIG. 1, a system according to an embodiment of the present invention includes an air pollution measuring apparatus 100, a portable terminal 200, and an external engine 300.

The air pollution degree measuring apparatus 100 has a semiconductor type gas sensor 101 connected to the portable terminal 200 and provided for measuring the concentration of air. In this case, the semiconductor type gas sensor 101 utilizes a change in electrical conductivity that occurs when a gas is brought into contact with the surface of the ceramic semiconductor. Since the semiconductor type gas sensor 101 is often used by heating in the atmosphere, a stable ceramic at high temperature can be mainly used . Ceramics often exhibit the properties of semiconductors. Among them, n-type semiconductors when the metal atoms are excessive, and p-type semiconductors when the metal atoms are deficient. A semiconductor having such a property that the electric conductivity of the ceramic semiconductor is high and the melting point is high, and is thermally stable in the use temperature range, is used for the sensor 101. That is, the semiconductor type gas sensor 101 is characterized in that it has many kinds of gas that can be detected because it shows a response to most toxic gas and combustible gas, and the sensor is easy to manufacture.

The portable terminal 200 is connected to the air pollution measurement apparatus 100 and calculates the air pollution degree based on the low data collected through the semiconductor type gas sensor 101 when the application is executed at the time of connection. Here, the application provides additional user interfaces such as preheating completion, display of measured values, actions according to measured values, detailed description of measured values as well as selection of measuring gas. In addition, the application uses the measurement algorithm to calculate the final air pollution degree by correcting the measured value by utilizing the processing capability of the portable terminal 200, the memory, the built-in sensor, and the communication function to the raw data.

In this case, a connection connector is provided between the portable terminal 200 and the air pollution measuring apparatus 100, or the air pollution measuring apparatus 100 is formed in the form of a USB port, So that it can be inserted into the receptacle.

The external organization 300 is an authorized organization and plays a role of transmitting weather information to the portable terminal 200.

2 is a view for explaining a configuration of an air pollution degree measuring apparatus according to an embodiment of the present invention. 2, the air pollution measurement apparatus 100 according to the embodiment of the present invention includes a power supply unit 110, a resistance measurement unit 120, a data collection unit 130, and a data transfer unit 140 .

The power supply unit 110 supplies power to the semiconductor type gas sensor 101 for measuring the concentration of air when the connection with the portable terminal 200 is completed and activates the power. At this time, the power supply unit 110 supplies the operation, the preheating temperature of the semiconductor type gas sensor 101 and the power for measurement based on the control setting information transmitted from the sensor control unit 240 of the portable terminal 200 . The power supply unit 110 stops power supply to the semiconductor type gas sensor 101 when a control command for deactivating the semiconductor type gas sensor 101 is transmitted from the portable terminal 200.

The resistance measuring unit 120 measures the resistance value of the semiconductor type gas sensor 101 activated through the power supply unit. The resistance measuring unit 120 measures a resistance value that varies depending on the activation time and temperature of the predetermined semiconductor type gas sensor 101. [

The data collecting unit 130 collects raw data according to a change in the resistance value measured through the resistance measuring unit 120. The data collecting unit 130 converts the analog data measured as the resistance value into digital data and generates it as low data and collects it.

The data transfer unit 140 transfers the row data collected through the data collecting unit 130 to the portable terminal 200. The data transmission unit 140 transmits the collected raw data to the air pollution degree measurement algorithm of the portable terminal 200.

3 is a diagram for explaining a configuration of a mobile terminal according to an embodiment of the present invention. 3, the portable terminal 200 according to the embodiment of the present invention includes an application execution unit 210, a gas selection unit 220, a weather information receiving unit 230, a sensor control unit 240, A final air pollution degree calculating unit 260, and a display unit 270. [0033]

The application executing section 210 is executed when the portable terminal 200 is connected to the air pollution measuring apparatus 100.

The gas selector 220 selects a gas to be measured. At this time, the gas selection unit 220 may select at least one of carbon dioxide, carbon monoxide, LPG (Liquefied Petroleum Gas) and alcohol as a gas to be measured.

The weather information receiving unit 230 receives weather information including at least one of current temperature, humidity, weather information, and atmospheric pollutant information from the external organ 300.

The sensor control unit 240 controls the operation of the semiconductor type gas sensor 101 according to the type of gas selected through the gas selection unit 220. The sensor control unit 240 variably sets and controls the current and voltage values supplied to the semiconductor type gas sensor 101 to be activated, the activation time and temperature of the semiconductor type gas sensor 101, and the like. Also, the sensor control unit 240 senses the operation of the semiconductor type gas sensor 101 after varying the activation time and temperature of the semiconductor type gas sensor 101. That is, the sensor control unit 240 determines whether the temperature of the semiconductor type gas sensor 101 is sufficiently high enough to be measured or sufficiently stable. If the temperature is sufficiently stable, the sensor control unit 240 displays the completion of preheating through the display unit 260.

The main operation of the sensor control unit 240 will be described in detail. First, the supply voltage / current and duration of the semiconductor type gas sensor 101 are changed according to the gas to be measured, . Second, the measurement result determines the measurable time using the different stabilization pattern for each gas. Third, the suitability of the measurement environment is determined by using the air pollution value received from the authorized organization or the air pollution degree measured by detecting the air pollution degree measurement pattern at the corresponding temperature during the above process. Fourth, the sensor resistance of the semiconductor type gas sensor 101 is low when the temperature is high and the sensor resistance is high when the temperature is low. Sensors are sensitive on hot and humid days and become dull on low temperature dry days. When the semiconductor type gas sensor 101 is blown, the surface temperature is lowered, and the sensor resistance is significantly changed. And the correction value is calculated using this. Fifth, slightly different measured value deviations for each particular gas are measured in advance at two reference concentrations for the corresponding semiconductor gas sensor 101 and stored in nonvolatile memory. The mobile terminal receives this and uses it to calibrate the measured value. Sixth, the portable terminal manages the frequency and duration of use of the semiconductor type gas sensor 101, and calculates a correction value for the characteristic change. The seventh calculates the final measurement value by reflecting the correction value determined above in the conversion formula.

The air pollution degree calculating unit 250 periodically receives raw data transmitted from the data transmitting unit 140 to calculate the air pollution degree.

The final air pollution degree calculation unit 260 calculates the final air pollution degree by referring to the air pollution degree calculated through the air pollution degree calculation unit 250 and the weather information received through the weather information receiving unit 230. [ For example, when the temperature is high, the resistance value of the semiconductor type gas sensor 101 is low, and when the temperature is low, the resistance value of the semiconductor type gas sensor 101 is high. At this time, when the semiconductor type gas sensor 101 is blown, the surface temperature is lowered and the resistance value is changed. Accordingly, the final air pollution degree calculating unit 260 calculates the final air pollution degree by correcting the air pollution degree calculated based on the weather information.

The display unit 270 displays the final air pollution degree calculated from the final air pollution degree calculating unit 260. [

4 is a flowchart for explaining the procedure of the air pollution measurement method according to the embodiment of the present invention. 4, the method for measuring air pollution degree according to an embodiment of the present invention is a method for measuring air pollution degree through a system including the air pollution degree measurement apparatus 100, the portable terminal 200, and the external engine 300, , And a repeated description will be omitted.
