Radon is one of the natural radioactive materials including uranium and radium, and it is the main carcinogen that threatens the health of the residents by causing lung cancer by daily exposure from the living environment such as indoor air. The World Health Organization (WHO) and the US Environmental Protection Agency (USEPA) recommend that radon be the major causative agent of lung cancer after smoking and should be managed in indoor air. Radon is present in outdoor air or groundwater, but most of it is occupied by indoor air (about 95%). Radon is generated from the infiltration through the gaps between the buildings and the radium contained in the building materials, Lt; / RTI >

In the past, it was only the primary concern to identify the causal relationship between damage and environmental pollution, but it is important to quantify and publicize the extent and severity of pollution damage in modern society, which requires quantitative information. .

FIG. 2 is a view showing an embodiment of the radon abatement equipment integrated control system shown in FIG. 1. FIG. 2, the radon sensor 11, the temperature sensor 12, the humidity sensor 13, the exhaust fan 14, the control box 15, and the set top box 31 are located at the A place. Since the radar sensor 11, the temperature sensor 12, the humidity sensor 13, the exhaust fan 14 and the control box 15 are connected to each other by a wire, Or wirelessly using a short-range wireless communication method. Similarly, the control box 15 and the set-top box 31 may be connected by wire or wirelessly using a short-range wireless communication method. Examples of the short-range wireless communication method include Bluetooth, Zigbee, Wi-Fi, and the like. The set-top box 31 may be equipped with a global positioning system (GPS) function, and the server 21 may track the position of the set-top box 31 scattered everywhere using the GPS function of the set- .

 And one base station 32 is located at the B place. In this embodiment, the set-top box 31 and the base station 32 wirelessly communicate with each other using an RF (Radio Frequency) communication network. The RF communication network may be a 900 MHz band communication network corresponding to a free frequency band of Radio Frequency Identification (RFID). Each RF base station 32 can communicate only set-top boxes located within a certain distance, for example, set-top boxes within a 10 Km radius, as the RF signal is reduced in size as it moves away from its source. When the A place and the B place are within this distance, the set-top box 31 of the place A and the base station 32 of the place B can communicate with each other by using the RF communication network. The base station 32 in place B mediates communication between the set-top boxes and the server 21 within a certain distance therefrom.

The set top box 31 and the base station 32 may be equipped with M2M (Machine to Machine) technology so that they can recognize each other and communicate with each other automatically. One server 21 and two clients 22 are located at location C. The base station 32 in the B place and the server 21 in the C place communicate with each other using a TCP / IP (Transmission Control Protocol / Internet Protocol) communication network. The server 21 at the location C and the two clients 22 at the location C communicate with each other using the TCP / IP communication network. The two clients 22 are located at the D location. The server 21 in the place C and the two clients 22 in the place D communicate with each other via the TCP / IP communication network. As shown in FIG. 2, each client 22 may be a variety of terminals capable of TCP / IP communication such as a PC (Personal Computer), a notebook computer, a smart phone, and the like.

Since the radon abatement facility 1 can be installed in a place where TCP / IP communication is impossible, such as a harbor facility or a railroad history waiting room, the set-top box 31 and the base station 32 can communicate with the control box 15 And intermediates the communication between the servers 21. Accordingly, the server 21 can monitor a large number of radon abatement facilities 1 scattered everywhere in real time through the communication path as described above. The server 21 collects data from a large number of radon abatement facilities 1 acquired through such real-time monitoring and databases them, and can remotely control the respective radon abatement facilities 1. In particular, the server 21 establishes a database by layering data of a number of radon abatement facilities 1 in order to systematically and easily manage and control a large number of radon abatement facilities 1 dispersed everywhere. The statistics of the data of the radon abatement facility 1 can be created and analyzed based on such a database. The database construction according to this embodiment will be described in detail below.

FIG. 3 is a diagram illustrating a communication protocol of the radon abatement equipment integrated control system shown in FIG. 1. FIG. Referring to FIG. 3, when the server 21 transmits a control message of a first format including a command for controlling the radon abatement facility 1 to the control box 15, the control box 15 normally receives the control message Or transmits a response message in a third format indicating that it is abnormally received. When the control box 15 transmits the data message of the second format indicating the data of the radon abatement facility 1 to the server 21, the server 21 indicates that it has normally received it or indicates that it has received abnormally 3 format response message. The server 21 has a data logging function and can record data of the radon abatement facility 1 in the order of occurrence time of data of the radon abatement facility 1. [ The communication protocol of the radon abatement equipment integrated control system according to the present embodiment can be implemented by serial communication using VC ++.

The sequence of the communication protocol according to the present embodiment is as follows. When the control message of the first format is transmitted from the server 21 to the control box 15, the response message of the third format is returned from the control box 15 to the server 21. The server 21 retransmits the control message when the response message returned from the control box 15 indicates that the control message has been abnormally received. When the data message of the second format is transmitted from the control box 15 to the server 21, the response message of the third format is returned. The control box 15 retransmits the data message if the response message returned from the server 21 indicates that the data message was abnormally received. As described above, in the present embodiment, the data of the radon abatement facility 1 can be reliably transmitted without error by continuously retransmitting the message until the message is normally received.

FIG. 4 is a diagram illustrating a format of the control message shown in FIG. In FIG. 4, the first line represents the definition of each field, the second line represents the code of each field, and the third line represents the ASCII value of each field. 4, the control message of the first format transmitted from the server 21 to the control box 15 includes a start of text (STX) field, a length field, a type field, a target field, a radon limit field, A data storage interval field, a checksum field, and an ETX (end of text) field. A code "0x02" indicating the start of the message is recorded in the STX field, and a length of the message expressed in two numeric formats is recorded in the length field. The ASCII value "31 34" recorded in the length field indicates that the length of this message is 14.

 A code "0x4F" indicating that the message is a control message is recorded in the type field, a code "0x53" indicating that the object to be controlled by the message is the exhaust fan 14 is recorded in the target field, Radon thresholds expressed in numerical format are recorded. The ASCII value "31 35 30" recorded in the radon limit field indicates that the limit value of the radon concentration in the indoor air of the building is 150. In the fan control field, the state value of the exhaust fan 14 represented by one numerical format is recorded. The ASCII value "30" recorded in the fan control field indicates that the exhaust fan 14 is turned off. If the ASCII value "31" recorded in the fan control field is recorded, this value indicates that the exhaust fan 14 is turned on.

The data storage interval field records the data storage interval expressed in three numeric formats. The ASCII value "30 30 31" recorded in the data storage interval field indicates that the data storage interval is one minute. For example, the storage interval of the data, that is, the storage period may be set to any one of 1 minute, 5 minutes, 15 minutes, 30 minutes, and 1 hour. A checksum value for checking the error of the data is recorded in the checksum field, and a code "0x03" for indicating the end of the message is recorded in the ETX field. The error checking of the data is performed using a value obtained by summing all the data from the STX field to the checksum field and a value recorded in the checksum field. Since this is a technique well known to those skilled in the art to which this embodiment belongs, Description thereof will be omitted.

However, the ASCII value "34 31" recorded in the length field indicates that the length of the message is 41, the code "0x44" indicating that the message is a data message is recorded in the type field, and data is recorded in the destination field Quot; 0x41 "indicating that the target is the whole is recorded.

The temperature field records the temperature value expressed in the form of two numbers and one decimal point. The ASCII value "30 32 36 2E 35" recorded in the temperature field indicates that the room temperature of the building is 26.5 degrees. The humidity field records the temperature value expressed in two numbers and one decimal point. The ASCII value "30 32 35 2E 32" recorded in the temperature field indicates that the room temperature of the building is 25.2%. The radon field records radon measurements expressed in three numerical formats. The ASCII value "30 34 34" recorded in the radon field indicates that the measured value of the radon concentration in the indoor air of the building is 44 Bq / ㎥.

In the fan status field, the state value of the exhaust fan 14 represented by one numerical format is recorded. The ASCII value "30" recorded in the fan status field indicates that the exhaust fan 14 is off. If the ASCII value "31" recorded in the fan status field is recorded, this value indicates that the exhaust fan 14 is on. In the current time field, a value indicating the current time at the time of generating this message is recorded as year / month / day / hour / minute / second. The generation of the data message is immediately performed after the built-in sensor measurement of the object recorded in the target field, i.e., the radon sensor 11, the temperature sensor 12, the humidity sensor 13, and the exhaust fan 14, The time of measurement of the data is almost the same.

The integrated control program is executed in a daemon format so that the server 21 can process data received from the base station 32 in real time while the server 21 is performing another task. The server 21 sets the radon limit value, whether or not the exhaust fan 14 is driven, and the data storage interval according to each radon abatement facility 1, that is, the object, generates a control message based on the set value, (32).

The server 21 extracts one message from the data received from the base station 32 by referring to the values of the STX field, the length field, and the ETX field. Then, the server 21 checks the data error of the message by referring to the value of the checksum field, and determines the type of the message by referring to the value of the type field if there is no error in the data. Then, if this message is a data message of the second format, the server 21 stores the data recorded in the data message in the database of the server 21 according to the data storage interval recorded in the data storage interval field do. Considering the recent trend of the importance of indoor air quality, there is a high possibility that a radon abatement facility will be installed in most buildings where people live in the near-term. In order to systematically and easily manage and control numerous radon abatement facilities scattered everywhere, a database is constructed as follows.

The server 21 stores data of a plurality of radon abatement facilities 1 dispersed everywhere in a plurality of categories in which a plurality of radon abatement facilities 1 are classified into a plurality of categories, , And subdivisions are hierarchized into subcategories classified into a plurality of radon influence factors to construct a database, and the plurality of radon abatement facilities 1 are integrally controlled based on the thus constructed database. The server 21 is configured to sequentially select one category, at least one place in the level of the sub class, and at least one radon influence factor in the level of the sub class, at the level of the major category, It controls the multiple radon abatement facilities sequentially in units of radon influence factor.

In the present embodiment, the radon influence factor refers to a factor that may affect the indoor radon concentration, and includes a radon concentration measured by the radon sensor 11, a room temperature measured by the temperature sensor 12, a humidity sensor 13 And the on / off state of the exhaust fan 14 measured by the built-in sensor of the exhaust fan 14, and the like. Since the radon concentration in the indoor air is not greatly affected by the indoor temperature or humidity, it is necessary to keep the room temperature and humidity constant since the performance of the radon sensor 11 may be influenced by the indoor temperature and humidity have. On the other hand, when the temperature difference between the indoor and the outdoor is remarkable, the radon generated from the underground soil of the building may flow into the room suddenly due to the formation of the air pressure which is lower than the air pressure of the underground soil of the building indoors.

The server 21 selects any one of the plurality of categories at the level of the large category and selects at least one place among the plurality of places of the category thus selected at the level of the middle class, In the course of sequentially selecting at least one radon influencing factor among the radon influencing factors of the plurality of sites, the radon abating facilities 1 in various places belonging to one category are collectively monitored, Detailed monitoring of the status of various radon influencing factors of the abatement facility (1) enables systematic and easy management and control of numerous radon abatement facilities scattered everywhere. If at least one of the various radon influencing factors in a category belonging to a category is abnormal, it may indicate that the category is abnormal at the level of the major category, and may indicate an abnormality for each of the radon influence factors at any location have.

Radon is a natural radioactive material that exists everywhere and is mainly found in soil, rock (granite), groundwater, building materials (gypsum board, etc.). Because most of the radon introduced into the room is originated from underground soil or rock, places such as underground history, underground shopping area, etc. tend to have higher concentration of radon in the indoor air than other places and need to be managed more concentrated than other places. On the other hand, since elderly people, patients, and infants are more likely to develop the same concentration of radon than healthy adults, places such as medical institutions, childcare facilities, elderly care facilities, and postpartum care centers where they live mainly need to be managed. Hereinafter, the place where a high concentration of radon is detected or a place where a person susceptible to radon tends to be present is referred to as a place having a high risk of damaging the radon.

In this embodiment, a plurality of radon abatement facilities (1) are classified into categories such as underground history, underground shopping malls, medical institutions, child care facilities, nursing homes, and postpartum care centers do. Accordingly, the user of the integrated control facility (2) can efficiently manage numerous radon abatement facilities (1) under limited management personnel by concentrating the categories in which places with high risk of radon damage belongs compared to other categories, It is possible to minimize the damage caused by the human being. Thus, the present embodiment can systematically and easily manage and control many radon abatement facilities scattered everywhere considering characteristics of each place for radon exposure damage, thereby minimizing loss of life due to exposure to radon under limited management personnel can do.

At the level of middle class, each category is classified into a plurality of places. Therefore, it is possible to compare the measurement data of various radon abatement facilities (1) installed in places having the same characteristics belonging to the same category. Therefore, it is necessary to grasp the cause of radon generation at each site, And it is possible to accurately determine the age, failure, etc. of the radon abatement facility. Accordingly, it is possible to eliminate the safety threat of residents due to prolonged failure of the radon abatement facility. In addition, by classifying each place of the subdivision into a plurality of radon influence factors at the level of the small classification, it is possible to easily find out the status of a plurality of radon influence factors at a place where the user wants to monitor.

FIG. 9-11 is a view showing an output screen of the integrated control program installed in the client 22 shown in FIG. In the embodiment shown in Figs. 9-11, the atmospheric pressure of the room is added as a radon influence factor. It is considered that radon generated from the underground soil of the building may be rapidly introduced into the room when the indoor air pressure is much lower than the air pressure of the underground soil of the building. When the integrated control program loaded on the client 22 is executed by the user of the client 22, the client 22 requests the server 21 for the major classification information. Then, the server 21 extracts the plurality of category name information from the database according to the large-category information request of the client 22, and provides the extracted information to the client 22. [ Then, the client 22 receives the plurality of category name information from the server 21 and displays the names of the plurality of categories in one screen. When any one of a plurality of categories displayed on the screen of the client 22 is selected by the user through a mouse, a touch screen, or the like, the client 22 requests the classified information. The classification information request of the client 22 includes the identification information of the category selected by the user.

Next, the server 21 extracts the name information of each of the plurality of places in the category selected by the user from the database and the name information of each of the plurality of the radon influence factors of each of the places in accordance with the request for the classification information of the client 22 To the client (22). Then, the client 22 receives the name information of each of the plurality of places of the category selected by the user from the server 21 and the name information of each of the plurality of radon influence factors of each of the places, And the name of each of the plurality of radon influencing factors of each of these places is displayed in one screen. 9, when one of the categories is selected by the user, a screen displaying the names of the plurality of categories at the level of the large classification is displayed at the level of the middle classification and the names of the plurality of places and the plurality of radon influences The name of the parameter is displayed.

 When any one of a plurality of places displayed on the screen of the client 22 is selected by the user, the client 22 requests the small classification information. The identification information of the place selected by the user is included in the small classification information request of the client 22. [ Subsequently, the server 21 extracts data of each of a plurality of radon influence factors at a place selected by the user from the database according to the request for the small classification information of the client 22, and provides the extracted data to the client 22. Then, the client 22 receives the data of each of the plurality of radon influence factors at the place selected by the user from the server 21 and displays data of each of the plurality of radon influence factors at the place selected by the user in one screen .

As shown in FIG. 10, when any one of the plurality of places is selected by the user, the names of the plurality of places and the names of the plurality of the radon influence factors of the places are displayed at the level of the sub- The data of each of the plurality of radon affecting factors is switched to the displayed screen. The change in the value of each radon influencing factor can be shown as a graph in which the x-axis is the time flow and the y-axis is the magnitude of the value of the radon influence factor. If it is not possible to display a graph of all the radon influence factors in one screen, it is possible to display multiple graphs in a superimposed manner as shown in FIG. 10, and display the graph selected by the user in front of the graph. Accordingly, the user can monitor the change of the plurality of radon influence factors at a desired place in detail.

When two of the plurality of places displayed on the screen of the client 22 are selected by the user and any one of the plurality of radon influence factors at the two places is selected, the client 22 requests the small classification information. The sub-category information request of the client 22 includes identification information of two places selected by the user and identification information of the radon influence factor. Subsequently, the server 21 extracts data of the selected two kinds of radon influence factors selected by the user from the database according to the request for the small classification information of the client 22, and provides the extracted data to the client 22. The client 22 then receives the data of the selected radon influencing factor for each of the two locations selected by the user from the server 21 and compares the data of the selected radon influence factor for each of the two locations selected by the user As shown in FIG. By comparing the data of the radon influencing factors measured by each of the two radon abatement facilities (1) installed at two places having the same characteristics, it is possible to accurately determine the aging and failure of the radon abatement facility.

As shown in FIG. 11, when two of the plurality of places displayed on the screen of the client 22 are selected by the user and one of the plurality of radon influence factors at two places is selected, the name of the plurality of places And a screen showing the names of a plurality of radon influencing factors of each of these places is switched to a screen comparing the data of each of the two radon influencing factors at the level of the sub-category. As described above, the client 22 can be a PC, a notebook computer, a smart phone, or the like. The entire number of various radon influencing factors of the various radon abatement facilities 1 distributed everywhere can be displayed on a small screen It is impossible to display.

According to this embodiment, when one of the categories is selected by the user, the screen displayed at the level of the large classification is switched to the screen displayed at the level of the middle classification, and when one of the places is selected by the user, , It is possible to confirm in which category the radon abatement facilities 1 are installed in a certain category and to ascertain which radon influence factors are measured by each of the radon abatement facilities 1, The value of the radon influencing factor to be confirmed can be monitored in detail. In other words, the user can monitor the change in the value of a certain radon influence factor, a graph comparing with other radon influence factors, etc., in a single screen.

In addition, the server 21 extracts from the database name information of each of a plurality of categories, name information of each of a plurality of places, name information of each of a plurality of radon influence factors, or data of at least one radon influence factor, (22), any one of the clients may specify the name of each of the plurality of categories, the name of each of the plurality of places, the name of each of the plurality of radon influence factors, or the data of at least one radon influence factor The client 22 does not need to have a large database in which the data of a large number of the radon abatement equipments 1 are recorded, thereby reducing the burden of data management on the client 22. It is possible to integrally control a plurality of radon abatement facilities 1 by using a thin and lightweight client 22 such as a smart phone.

The user determines the radon limit value and the on / off interval of the exhaust fan 14 according to the risk of the radon damage according to each category, and controls the exhaust fan 14 of the radon abatement facility 1 according to the determined value Command to the client 22. The client 22 transmits this command to the server 21 when a command for controlling the exhaust fan 14 of the radon abatement facility 1 installed at the place selected by the user is input from the user. The server 21 has a field indicating the object of the radon abatement facility 1 to be controlled by the command transmitted from the client 22, that is, the field indicating the exhaust fan 14, a field indicating the radon limit value, A field indicating a state or an off state, and transmits a control message to the radon abatement facility 1 installed at a place selected by the user via the communication network facility 3. [ As described above, according to the present embodiment, the operation of any one of a large number of radon abatement facilities 1 scattered everywhere, for example, the exhaust fan 14, can be performed freely by the user of the client 22 located at a remote location Can be controlled.

The user can determine the data storage interval of the database based on the risk of radon damage in each category for each category. For example, a data storage interval for a category in which a radon concentration tends to be detected at a high level or a place where a person with a vulnerable radon is located may be shortened compared to other categories, and a data storage interval may be extended for another category. That is, the server sets a data storage interval of the database on the basis of the risk of radon damage in each category for each category, and transmits a control message including a field indicating the data storage interval to a plurality of places To the radon abatement facility 1 installed in each of them. Next, each radon abatement facility 1 measures data for a plurality of environmental factors as described above according to the data storage interval recorded in the control message, and transmits a data message including the measured data to the communication network facility 3 To the integrated control facility (2).

Accordingly, it is possible to intensively monitor the radon abatement facility (1) in a place belonging to a category having a high risk of radon damage without excessive use of communication resources, thereby minimizing casualties caused by exposure to radon. On the other hand, each server 21 can increase or decrease the data storage interval in proportion to the amount of change of data measured by the radon abatement facility 1 installed in each building for each place. The large change in the data measured by the radon abatement facility (1) means that the concentration of radon in the indoor air of the building can be increased rapidly. According to this embodiment, it is possible to intensively monitor the radon abatement facility 1 in such a place, thereby minimizing casualties caused by radon exposure. The above-described database can be implemented in the form of a relational database management system (RMDBS) by Oracle's mySQL as follows.
