Equipment automatic modeling pre-acquisition system based on MQTT

The invention discloses a MQTT-based equipment automatic modeling front acquisition system, which comprises side equipment and an Internet of Things platform, and is characterized in that the Internet of Things platform comprises a front protocol module and a background; and an object-oriented data transmission protocol MQTT with interoperability is adopted between the side equipment and the Internet of Things platform to carry out equipment creation, equipment updating, equipment deletion, data interaction and bidirectional authentication encryption transmission. The method has the advantages that the terminal equipment is modeled and the data is analyzed and stored by analyzing the uploaded message, so that automatic modeling of the terminal equipment is realized, the working efficiency of power distribution Internet of Things acquisition is improved, and the maintenance time cost is reduced; the information interaction between the Internet of Things platform and the side equipment is based on SSL/TLS bidir
