Abstract

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.

Description

technical field [0001] The present invention relates to the field of wireless communication technology, in particular to a fire rescue site monitoring system based on NB-IoT technology. Background technique [0002] In today's life, fire cases occur from time to time, and the environment of the fire site is changeable, especially the indoor fire site may be filled with toxic gas, combustible gas, a large amount of smoke particles and dust, causing secondary accidents of poisoning and explosion, which is harmful to the trapped people. and firefighters causing great personal injury. How to monitor the environmental information of the fire rescue scene and the location information of firefighters in real time, so as to implement fire control and rescue, reduce the risk of rescue, and ensure the personal safety of trapped people and firefighters is a crucial issue. The location of the fire site is uncertain, and it is difficult to quickly monitor the fire site environment in re...
