Here, the communication module 240 may transmit the corresponding data by communicating with the repeater 120 at a predetermined period (eg, 1 to 3 seconds).

The repeater 120 may relay the sensing data received from the sensor device 110 and transmit it to the monitoring server 130. To this end, the repeater 120 may be configured to communicate with each other between the sensor device 110 and the monitoring server 130.

The repeater 120 may be installed in various places in an industrial site such as a construction site, and it is preferable that a plurality of repeaters 120 are installed for smooth communication between the sensor device 110 and the monitoring server 130.

Meanwhile, the repeater 120 may include a function of measuring oxygen saturation, carbon dioxide, temperature, harmful gas, fire, etc., thereby further improving the efficiency of the safety protection management system 100.

The repeater 120 may be selectively provided in the safety protection management system 100 according to an embodiment of the present invention. That is, since the repeater 120 is optional, communication between the sensor device 110 and the monitoring server 130 is possible without the repeater 120, but the repeater 120 may be used in an incommunicable area such as a shaded area. It is preferred to use. When the repeater 120 is not provided in the safety protection management system 100 according to an embodiment of the present invention, the sensor device 110 and the monitoring server 130 have a dedicated frequency (eg, 400 Mz) like a walkie-talkie. Can be used to communicate.
