LPWA A LOW POWER WIDE AREA SAFETY NETWORK SYSTEM BY USING A LPWA COMMUNICATIONS

摘要

The present invention provides a low power wide area disaster safety net system based on cloud sensor communication network which can simultaneously process a large amount of sensor data by using a complex multi IoT sensor applying a convergence LED lighting system and low power wide area (LPWA) communication network. The system comprises: a sensor part capable of monitoring fire and toxic gas concentration; a display direction guide light inducing the direction of an emergency exit, and guiding so as to avoid an entry into a dangerous region; an emergency exit sign guide light informing a final emergency exit according to the direction of the induced emergency exit; and a cloud server receiving monitoring information from the sensor part in real time, drawing a path of the final emergency exit, and transmitting a control command with respect to the display direction guide light and the emergency exit sign guide light.
