Please give the technical principles and technical problems that can be solved for the following technologies (the two pieces of content are displayed in sections and start with "technical principles:" and "technical problems that can be solved:"): The present invention relates to the technical field of device message exchange, In particular, it relates to a high-performance Internet of Things platform message engine, including a receiving module, a first-level queue module, a processing module, a second-level queue module, a business module and a sending module. The present invention reduces the package body size of each message data by packing and compressing the message data, monitors the real-time total data volume of the first message queue through the processing module, adjusts the first message queue, and according to any message The data volume of the data compression package determines whether to adjust the position of the message data in the first message queue, so as to adjust the processing order according to the capacity of the first message queue, improve the processing efficiency of the message data, and realize the high concurrency of the message engine. The lightweight protocol transmits data, reduces traffic transmission, and transfers massive uplink data to the first message queue, and then the processing module processes the data and provides it to the user system to achieve high throughput. 1. A high-performance Internet of Things platform message engine is characterized in that it includes
