Building fire control diagnostic system based on thing networking and artificial intelligence Technical Field The invention relates to the field of electric digital data processing, in particular to a building fire-fighting diagnosis system based on the Internet of things and artificial intelligence. Background Along with acceleration of urban process and complicating building functions, the demands of intelligent and accurate building fire safety are increasingly highlighted, the deep fusion of an internet of things (IoT) technology and an Artificial Intelligence (AI) technology provides core support for upgrading building fire diagnosis, and the intelligent fire diagnosis system has the main stream development direction of the building fire diagnosis system by acquiring electric digital data such as the running state of fire equipment, communication link parameters and the like through an internet of things terminal and combining an artificial intelligent model to realize data analysis and intelligent decision. The application of the Internet of things technology in the building fire diagnosis system is characterized in that the interconnection and intercommunication of the fire control gateway, the sensor and the controller are realized through low-power consumption wide area communication protocols of LoRa and NB-IoT, and a fire control data acquisition network covering the building universe is constructed. However, because the building fire scene has the characteristics of complex environment, distributed equipment, dynamic change of communication requirements and the like, the fire-fighting internet of things gateway is used as a core hub for data transmission, and the communication stability of the fire-fighting internet of things gateway directly determines the real-time performance and reliability of fire-fighting data, so that the data processing is required for the electric digital electric data in the link communication states of packet loss rate, delay, integrity, signal strength, gateway connection equipment quantity, data throughput and the like of fire-fighting communication, and the optimal communication protocol in the current building fire-fighting fire state is further determined, and the timeliness of fire-fighting diagnosis results is further ensured. And further, the problem that key data such as smoke concentration, temperature and the like in the initial stage of a fire disaster cannot be transmitted in time due to communication packet loss or delay is avoided, so that alarm is delayed, and the optimal treatment time is missed. At present, the prior art mostly adopts a fixed communication protocol to deploy a fire gateway of the Internet of things, or adjusts the communication protocol through simple parameter threshold judgment, and the fire gateway does not combine the characteristics of a fire scene of a building. On the one hand, the wireless communication environment difference of different building areas of high-rise buildings and underground garages is obvious, so that signal shielding and interference intensity of different areas are different, a fixed communication protocol cannot adapt to diversified communication scenes, and dynamic balance of packet loss rate, delay and communication integrity is difficult to realize. On the other hand, the existing scheme lacks systematic processing of the electric data of the communication link of the fire prevention, only evaluates the communication quality through a single parameter or a simple algorithm, does not construct an accurate utility evaluation model, and cannot generate an optimal communication protocol label adapting to a real-time scene, so that blindness of protocol selection is caused. In summary, how to perform evaluation processing of adapting to building fire-fighting diagnosis communication utility on electric digital data of internet of things communication, so as to determine an optimal communication protocol of building fire-fighting diagnosis, so as to improve communication stability of internet of things building fire-fighting diagnosis is a technical problem to be solved at present.
