The operation of the gas container checkout and monitoring system suitable for the Internet environment having the above-described configuration will be described in detail as follows.

In order to manage the safety of the gas container, the characteristics of the reader (or scanner) 200 that senses the communication method of the gas tag 100 attached to the gas container 1 and the signal of the tag, and the information The process of transmitting is important.

According to this importance, the present invention utilizes the fact that a low-power long distance communication technology (for example, LoRa) infrastructure supporting the Internet of Things (IoT) environment has been established and a small amount of data can be transmitted at a low communication cost, And the Internet terminal device is applied to manage the gas container.

For example, as shown in Fig. 1, the gas tag 100 is attached to the gas container 1, and the gas containers to which the gas tags are attached are stored in the gas container 2, 200) at a predetermined position of the gas container (2), and monitors the gas containers in real time.

The BLE communication module 120 of the gas tag 100 attached to the gas container 1 transmits a signal at a predetermined period and the signal emitted from the gas tag 100 is sensed by the scanner 200. The signal transmission period of the gas tag 100 can be set by the control server 310. The signal transmission period information set by the control server 310 is transmitted to the low power long distance communication module 230 of the scanner 200, The BLE control module 250, the BLE communication module 210 and the antenna interface 280 are sequentially transmitted to the gas tag 100 via the BLE communication, which is a Bluetooth 4.0 communication.

The signal transmission cycle is received by the gas tag 100 via the internal antenna 10 and the BLE communication module 120 of the gas tag 100 and the BLE communication module 120 stores it in the memory 160, And transmits a signal based on a signal transmission cycle.

Herein, a signal including a unique identification ID assigned to each gas tag stored in the gas tag identification information storage module 130 is transmitted when a signal is transmitted. Here, the gas tag identification information storage module 130 may be configured to restrict access (read) for security. When further enhanced security is required, the gas tag identification information storage module 130 may be configured using a separate hardware chip. The storage (writing) of the identification ID information unique to the gas tag 100 is performed by communicating between the BLE communication module 210 of the scanner 200 and the BLE communication module 120 of the gas tag 100, The control server 340 transmits the identification ID information of the designated gas tag 100 to the scanner 200. The scanner 200 transmits the identification ID information to the designated gas tag 100 and the gas tag 100 stores the received identification ID information in the gas tag identification information storage module 130. [

Such a gas tag 100 can be used for a long period of time by using a battery module 150 designed for low power consumption for use in the object internet environment. Upon request of the battery residual quantity data of the gas tag 100 at the control server 340, the BLE communication module 120 matches the remaining battery state information and the gas tag identification information (unique identification ID) (200). The central control module 220 of the scanner 200 stores the remaining battery level information transmitted from the gas tag 100 in the memory 240 and transmits the information to the control server 340 through the low power long distance communication module 230 . In this case, the central control module 220 drives the LED through the battery status display module 170 to allow the administrator to visually check the battery level when the remaining battery level drops below a certain level. For example, if it is normal, it should be green, and if it needs to be replaced, mark it as red.

On the other hand, the acceleration sensor 140 of the gas tag 100 detects a sudden movement of the gas container 1. Since the gas container (1) is roughly handled at the construction site, the acceleration sensor information is used as a function of grasping such a working environment, that is, work environment information. For example, when roughly handling a specific gas container, the gas container identification ID (gas tag identification ID) and the situation occurrence time data are transmitted to the control server 340 and stored, and a warning function To induce the operator to be alert. Here, the operator can directly inform the operator of the rough handling of the gas container by using a method of verbally notifying the operator, or sending a warning message to the operator by using a text message or an e-mail.

Further, as another feature of the present invention, the gas tag 100 is capable of protecting the gas tag 100 from external impact by the impact preventing device 180. It is often the case that the gas container (1) is roughly handled at the construction site. Therefore, in order to protect the gas tag 1 from an external impact, the gas tag 1 is embodied as a single body with the gas tag 1 using a shock absorber to protect the gas tag 100 from external impact. It is preferable to implement such a mechanical device so as not to deteriorate the communication performance of the built-in antenna 110.

The gas container attaching device 190 is a device for attaching the gas tag 100 to the gas container 1, and is preferably implemented in a form that is easy to attach and detach.

Meanwhile, the scanner 200 receives the origination signal of the gas tag 100 using the BLE communication module 210. The BLE communication module 210 can scan a signal transmitted from a plurality of gas tags at one time and sense the entire gas tag. The scan period of the signal transmitted from the gas tag 100 is periodically executed. The scan period can be set in the control server 340, and the set period is stored in the memory 240 of the scanner 200.

The BLE control module 250 controls the operation of the BLE communication module 210 and activates the scan function of the BLE communication module 210 according to the scan period of the gas tag origination signal stored in the memory 240. Only the designated gas tag can be configured to be detectable, thereby preventing detection of other nearby BLE communication devices, thereby realizing efficient control.

The scanner identification information module 260 of the scanner 200 stores each unique identification ID information assigned to each scanner, and is configurable to restrict access (read) by applying security. If more enhanced security is required, the scanner identification information module 260 may be configured using a separate hardware chip. The identification ID information of the scanner designated by the control server 340 is stored in the scanner (not shown) in the state where the scanner ID information is stored (written) in the communication between the low power long distance communication module 230 of the scanner 200 and the control server 340 200, and the scanner 200 stores the received identification ID information in the scanner identification information module 260.

The low-power long-range communication module 230 of the scanner 200 is a low-power long-range wireless communication module used in the Internet of objects, and can be configured by applying LoRa, SigFox, NB-IoT, LTE-M, The low power long distance communication module 230 provides communication between the scanner 200 and the control server 340 so as to transmit the information of the gas tag 100 to the control server 340 or control signals of the control server 340 Tag 100 and allows the scanner 200 to be controlled.

Also, the GPS module 270 of the scanner 200 automatically provides the location information of the scanner 200. When the position of the installed scanner 200 is moved without the prior change permission, the scanner 200 automatically detects the position of the installed scanner 200 and transmits information to the control server 340 about the change in the scanner installation position, Thereby providing a warning function for the positional change of the scanner 200.

The scanner 200 includes a first power source unit 290 that operates as a battery and a second power source unit 291 that operates as a constant power source. The first power source unit 290 operates as a battery when the power is turned off at all times, To the control server 340, and executes the emergency procedure according to the power-off at all times.

As described above, according to the present invention, it is possible to configure a terminal for a things Internet including a BLE short-range communication module and a low-power long-distance communication module to enable transmission of the gas tag information at a low communication cost through a low-power long- It is possible to simultaneously detect a plurality of gas tag signals using a reader (scanner). Such a system can be applied to a gas container and a gas container holder of a construction site to safely manage the gas container.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It is obvious to those who have.

The present invention is applied to a technique for monitoring and safely managing a gas container used in a construction site in real time.
