The camera module 130 may include a plurality of camera devices, and may include a camera device installed at a specific location of the facility where abnormal operation is likely to occur.

The first communication module 140 transmits audio information and video information collected from the microphone module 110 and the camera module 130 to the operation server 500 and transmits audio information and audio information corresponding to the corresponding method from the operation server 500. [ Signal. The first communication module 140 may be configured as a wired / wireless communication means. For example, the first communication module 140 may be an Ethernet-based Internet communication network as the wired communication means, and may be a mobile communication network based on 5G, 4G or LTE Can be configured.

A plurality of microphone modules 110, a speaker module 120, a camera module 130 and a first communication module 140 may be installed in a predetermined area unit in a work site, As shown in FIG.

The sensor module 150 is installed in a specific facility and collects information such as the temperature of the facility, the ambient humidity, and the distribution gas. The facility may be a power line, a fire line, or a communication line, and the sensor module 150 may be a complex sensor module including a temperature sensor, a humidity sensor, and a gas sensor. Generally, power lines in the ground are bonded at intervals of 300 meters, and most of the abnormality in the power line occurs at the joints. Therefore, a plurality of sensor modules 150 may be installed at intervals of 300 meters , And is installed closely to the surface of the line to accurately measure information on the power line. Each of the sensor modules 150 may be installed at different intervals depending on the type of the installed power line or environment.

Information such as temperature, humidity, gas distribution, and the like sensed by the sensor module 150 is transmitted to the operation server 500 and integrated management is performed to detect an abnormality in advance to prevent an accident.

The second communication module 160 transmits the information collected by the sensor module 150 to the operation server 500. The second communication module 160 is composed of a communication module that can use a mobile communication network installed for communication of a portable terminal such as a smart phone. Therefore, it is not required to construct a separate wired / wireless communication facility for transmitting information between the sensor module 150 and the operation server 500, and a communication module is simply installed in the sensor module 150, There is an advantage that the information to be collected can be transmitted.

For example, the second communication module 160 may be an IoT (Internet of Thing) module capable of communicating using the LTE communication network. In particular, the second communication module 160 may include an NB-IoT (Narrow Band IoT) module. The NB-IoT module is a communication method for intermittently transmitting a small amount of information. When applied to a communication module for transmitting information collected in the sensor module 150 to the operation server 500 as in the present invention, So that information can be transmitted to the operational server 500 with optimum efficiency.

In general, the information transmission of the IoT module using the LTE communication network is performed by the main data line. In this case, a large amount of information can be transmitted and the information transmission speed is high, but the cost of information transmission is high.

On the other hand, the NB-IoT module is suitable for transmitting a small amount of information by transmitting a low capacity information by utilizing the 180 kHz bandwidth corresponding to one resource block which is the minimum unit of resource allocation. Therefore, since a simple low-capacity information such as temperature, humidity, and gas information collected is intermittently transmitted between the sensor module 150 and the operation server 500, the second communication module 160 (NB-IoT module) Is advantageous in that one operating server 500 can efficiently accommodate a plurality of sensor modules 150. [

In addition, since the NB-IoT simplifies the wireless signal and further increases the transmission distance, information can be transmitted and received even in a place where a radio signal is not connected, such as an underground space. Therefore, the second communication module 160 can be usefully applied to the detection of facilities installed in an underground duct or the like, and enables efficient monitoring and management of the sensor module 150 installed in the underground area.

In addition, the second communication module 160 using the NB-IoT module is configured to transmit information using a resource block of a guard band in a resource block defined in the LTE frequency band. In the LTE frequency band, a guard band of a 180 kHz bandwidth is inserted between LTE data bands (regular LTE data bands) for transmitting normal data. Therefore, the second communication module 160 transmits information using the guard band of the LTE communication, and has the advantage of transmitting information at low power without interfering with the LTE data.
