As shown in FIG. 1 , the harmful gas detection system 90 according to the embodiment of the present invention includes a wearable device 100 , a user terminal device 110 , a communication network 120 , a control device 130 , and a third-party device. (140) in part or in whole.

Here, “including some or all” means that some components such as the third-party device 140 are omitted so that the harmful gas detection system 90 is configured, or a part of the components constituting the control device 130 or All of which refer to a network device (eg, a wireless switching device, etc.) constituting the communication network 120 or to be configured by being integrated into the user terminal device 110, including all in order to help a sufficient understanding of the invention described as

The wearable device 100 includes smart safety boots of workers working in a workplace or smart safety boots worn by ordinary people according to an embodiment of the present invention. Of course, the embodiment of the present invention exemplifies smart safety boots, but the wearable device 100 according to the embodiment of the present invention may further include various devices such as smart work clothes worn by workers in addition to the smart safety boots. Above all, as for the wearable device 100 according to the embodiment of the present invention, it is appropriate for workers or ordinary people to wear articles that are always worn when they are in an arbitrary space. For example, shoes are always in the same space with users, even when ordinary people stay in accommodations. In addition, in the case of work shoes worn by the workers, they always coexist in the workplace of the workers. As described above, the wearable device 100 according to the embodiment of the present invention is preferably an object that exists together with users in an arbitrary space. For example, the wearable device 100 may include a device such as Galaxy*Gear of domestic company S. However, such an electronic device is not always carried by users in an arbitrary space, and such an electronic device is preferably included in the category of the user terminal device 110 as an article corresponding to a smartphone in the embodiment of the present invention.

The wearable device 100 according to an embodiment of the present invention may include smart safety boots, and the smart safety boots include an insole 101 as shown in FIG. 2A , and the insole 101 includes a workplace or A smart device 103 having a sensor for detecting a harmful environment (or hazardous situation) such as a noxious gas in an arbitrary space of the accommodation may be mounted. In general, a shoe consists of an upper, an insole, a midsole, and an outsole.

2a, (a) of FIG. 2a shows the front surface in contact with the user's sole, and (b) of FIG. 2a shows the rear surface of the insole 101 in contact with the midsole. A smart device 103 according to an embodiment of the present invention is mounted on the rear side. More precisely, it may be inserted and fixed into the fastening groove formed on the rear surface. The smart device 103 is protected by an external case in a state in which the circuit board and the battery are vertically stacked or horizontally stacked, as can be seen in (c) and (d) of FIG. 2A. 2A (b) shows the smart device 103 inserted into the fastening groove of the insole 101 by accommodating the circuit board and the batter in the outer case. At this time, as shown in (b) of FIG. 2A , the outer case may have a plurality of holes formed on one side connected to the bottom surface of the insole 101 and the other side opposite thereto, that is, at least one side. Here, it can be seen that the formation of a plurality of holes in the outer case is to increase gas permeability so that the internal gas sensor can smoothly sense the harmful gas. In addition, the insole 101 (or the injection molding of the bottom surface) into which the smart device 103 according to the embodiment of the present invention is inserted may be made of durable PU foam (Polyurethane foam).

The electronic circuit configured on the circuit board may be composed of a CPU or MPU and its peripheral circuits. Of course, although the PCB substrate is exemplified as the circuit board in FIG. 2A, it may be possible to use a flexible PCB (FPCB) having flexibility. In the embodiment of the present invention, the configuration of the sensor mounted on the smart insole 101 can be divided into three methods. Here, as the sensor, a thin film sensor for detecting harmful gases such as carbon monoxide (CO) or carbon dioxide (CO _{2 ) is applied.} First, looking at the method of configuring the sensor, that is, the smart device 103 in the insole 101, a single-stage insertion method in which the sensor is inserted between the foam and the foam, the sensor is inserted between the foam and the fabric. There is a two-stage insertion method that applies to the insole with a structure that prevents distortion by bonding EVA injection molding to the bottom part. However, in the embodiment of the present invention, it will not be particularly limited to the method as in FIG. 2A.

Above all, in relation to the thin film sensor, the sensor configured in the smart device 101 according to an embodiment of the present invention to detect harmful gases is a different type of gas, such as carbon dioxide (CO ₂ ) or carbon monoxide (CO) gas. It is configured to measure the presence and concentration of gas by measuring the change in voltage versus voltage applied during gas reaction using a metal oxide that reacts differentially to the gas. That is, it measures the state of the gas. As shown in FIG. 2B, the sensor according to the embodiment of the present invention has a resistance of the sensor due to a change in resistance when a gas set as a target is in contact between two mutually open electrodes in an electrical resistance type as shown in FIG. 2B. It is a method of detecting gas while changing. Therefore, the most ideal sensor has a basic resistance value when gas is not detected, and a change in resistance occurs when gas is detected. Since the size of the sensor contact surface and the gap between the electrodes may be formed in various ways, the embodiment of the present invention will not be limited to any one shape.

The sensor according to an embodiment of the present invention is a multi-purpose sensor to which a multi-functional material technology is applied, rather than a discontinuous sensor method. FIG. 2B (a) shows a sensor electrode pattern, and FIG. 2B (b) shows a sensor electrode pattern after application of a sensing material. As a result of measuring the resistance value after applying the gas sensing material in the experiment, electrode pattern A showed a low resistance value of 0.9Ω, while electrode pattern C, which is different from other electrode patterns made of gold foil, showed the highest resistance value of 1.8kΩ, Electrode pattern C showed a resistance of about 1.5 kΩ, whereas electrode pattern D with a small sensor contact surface showed a higher resistance value of 5.3 kΩ, confirming that the pattern of electrode D exhibited the largest difference value when reacting with gas.

Of course, various factors may be considered in inserting the harmful gas sensor into the insole 101, for example. As a factor for the shape and arrangement of the sensor, the detection sensitivity of harmful gases may vary depending on the position (eg, the thickness of the insole) and the shape (eg, the shape of the thin film and the sensor arrangement) in the insole 101 where the sensor is inserted. Because. Therefore, it can be seen that the insole 101 of the smart safety boots according to the embodiment of the present invention takes this point into consideration. This is well illustrated in Figure 2a. In addition, the sensor according to an embodiment of the present invention can be used for a long time in an NFC-based no-power method and a low-power-based BLE method, so that efficient power consumption of the smart insole 101 and safety boots can be achieved.

The user terminal device 110 of FIG. 1 includes a smartphone, etc. possessed by general users or workers who perform tasks in an arbitrary space. Of course, even in the case of a smartphone, it is one of the items that users or workers always carry. For example, in a job site handling gas, etc., workers may have a smart phone or the like. In addition, there is no need to put the smartphone outside unless the general user staying in the accommodation only leaves the smartphone in the space where he or she is staying. In this respect, the user terminal device 110 corresponds to the wearable device 100 and an article worn and carried by workers or general users at all times. According to an embodiment of the present invention, the user terminal device 110 constitutes a visual screen, or an image display device capable of viewing an image is preferable.

For example, when the user terminal device 110 analyzes the sensing data collected from the nearby smart device 103 , an immediate response to an event or accident may be possible. This is because a delay time for processing data through the communication network 120 can be reduced.

The user terminal device 110 according to an embodiment of the present invention may perform operations such as data digitization, data collection and analysis, data transmission, and real-time inspection. The sensed data of the analog signal collected from the sensor can be digitized and transmitted to the control device 130 , and the sensed data can be analyzed by itself, and a real-time check of harmful gas in an arbitrary space can be performed by the user. For example, in the user terminal device 110, an application (hereinafter, an app) for using an operation, that is, a service according to an embodiment of the present invention may be installed. Therefore, by executing the app, it is possible to check the log record of the sensor according to the change of time, for example, the analysis result of the harmful gas in the arbitrary space where the user is located on the screen.

Of course, since it is possible to use a nearby wireless router, etc., it will not be particularly limited thereto. Sensing data is collected by performing short-distance communication such as Bluetooth with the smart device 103 mounted in the smart safety boots, and if necessary, the collected sensing data is analyzed and an alarm sound is generated through a sound output unit such as a speaker provided by itself. may cause Of course, when a speaker or the like is provided in the smart device 103 mounted on the smart safety boots, a warning sound may be generated through the smart device 103 .

In addition, when the user terminal device 110 transmits the sensing data collected by communicating with the nearby smart device 103 to the control device 130 of FIG. 1 , it is located together with its device identification information (eg, device ID). information can be transmitted. Of course, in order to generate location information, communication is performed using a global positioning system (GPS) and a GPS module in this process, and then the corresponding coordinate values calculated through triangulation, etc. can be transmitted as location information. The location information may be transmitted in the form of latitude and longitude information or coordinate values. Of course, since the user terminal device 110 such as a smartphone has its own acceleration sensor or gyro sensor, it is possible to generate its own location information through this, so it is not particularly limited to how the location information is generated. will be. For example, the control device 130 may position the user terminal device 110 from a communication company and use the positioning information as location information.

The communication network 120 includes both wired and wireless communication networks. As the communication network 120 , a wired or wireless Internet network may be used or interlocked. Here, the wired network includes an Internet network such as a cable network or a public telephone network (PSTN), and the wireless communication network includes CDMA, WCDMA, GSM, Evolved Packet Core (EPC), Long Term Evolution (LTE), and Wibro networks. meaning to include Of course, the communication network 120 according to the embodiment of the present invention is not limited thereto, and may be used as an access network for a next-generation mobile communication system to be implemented in the future, such as a cloud computing network and a 5G network under a cloud computing environment. When the communication network 120 is a wired communication network, the access point in the communication network 120 can connect to a switching center of a telephone company, etc., but in the case of a wireless communication network, it accesses the SGSN or GGSN (Gateway GPRS Support Node) operated by the communication company to process data or , BTS(Base Transceiver Station), NodeB, e-NodeB, etc. can be connected to various repeaters to process data.

The communication network 120 may include an access point. Access points include small base stations, such as femto or pico base stations, which are often installed in buildings. Here, the femto or pico base station is classified according to the maximum number of user terminal devices 110 that can be connected to the small base station. Of course, the access point includes a short-distance communication module for performing short-distance communication such as Zigbee and Wi-Fi with the user terminal device 110 . The access point may use TCP/IP or Real-Time Streaming Protocol (RTSP) for wireless communication. Here, short-distance communication is performed in various standards such as Bluetooth, Zigbee, infrared (IrDA), UHF (Ultra High Frequency) and VHF (Radio Frequency) and ultra-wideband communication (UWB) in addition to Wi-Fi. can Accordingly, the access point may extract the location of the data packet, designate the best communication path for the extracted location, and deliver the data packet to the next device, for example, the controller 130 along the designated communication path. The access point may share several lines in a general network environment, and includes, for example, a router, a repeater, and a repeater.
