Fuente: Wipo "IOT" The present invention relates to an Internet of Things (IoT) management hub device for construction sites that can integrate and manage IoT devices for smooth connection between IoT devices at a construction site where communication signals are weak. The Internet of Things (IoT) management hub device for construction sites that manages Internet of Things (IoT) devices in a construction site and performs Internet networking with a remote control server comprises: a first communication module connected to an IoT device through an IoT network using any one of ZigBee, Z-Wave, and Bluetooth wireless communication; a second communication module connected to a wireless access device responsible for relaying data with the control server through Wi-Fi HaLow; a sensor module detecting the internal and external temperature and humidity of an IoT management hub device; a control module generating transmission data by combining state data with received data received through the first communication module based on a communication protocol negotiated in advance with the control server, transmitting the same to the control server through the second communication module at each predetermined transmission period, and transmitting a control signal received from the control server to a corresponding IoT device through the first communication module; and a battery providing power necessary for the operation of the IoT management hub device.
