Fecha de publicación: 13/04/2018 Fuente: Wipo "IOT" The invention provides an NB-IoT technology based fire rescue field monitoring system. The system includes an NB-IoT sensing unit, an NB-IoT base station, an NB-IoT core network, a monitoring server and a remote monitoring center. The NB-IoT sensing unit is connected with the NB-IoT base station. The NB-IoT base station is connected with the monitoring server through the NB-IoT core network. The monitoring server is connected with the remote monitoring center. The NB-IoT sensing unit is used for collection, cushion, pre-treatment and transmission of data information including fire rescue fieldenvironment and firemen positions. The NB-IoT base station receives original data packets sent by the corresponding NB-IoT sensing unit, packs the original data packets into data formats meeting Ethernet standards according to a TCP/IP protocol and is connected with the monitoring server through the NB-IoT core network. The monitoring server receives the TCP/IP data packets for data access by theremote monitoring center. According to the invention, the system is long in communication range, low in power consumption and convenient to carry, and can meet requirements for real time monitoring of a fire rescue field effectively.
