The invention discloses an RS485 bus-based self-adaptive monitoring analysis method for communication of a power Internet of Things terminal, which overcomes the defects in the prior art and comprises a monitoring step and an analyzing step. The monitoring step specifically comprises the following steps: 1, acquiring RS485 bus communication parameter configuration; 2, setting an RS485 bus communication baud rate, a data bit, a check bit and a stop bit, and starting communication message interception; 3, judging whether the message is monitored or not, if the message is not monitored, obtaining a new RS485 bus communication parameter, returning to the step 2, and if the message is monitored, entering an analysis step; after the analysis step is completed, recording the communication parameters of the RS485 bus, and restoring the communication data. 本发明公开了基于RS485总线的电力物联终端通信自适配侦听解析方法，解决了现有技术的不足，包括侦听步骤和解析步骤，侦听步骤具体包括：步骤1，获取RS485总线通信参数配置；步骤2，设置RS485总线通信波特率、数据位、校验位、停止位，启动通信报文侦听；步骤3，判断是否侦听到报文，如果未侦听到则获取新的RS485总线通信参数，返
