Research And Design Of Power Tower Status Remote Monitoring System Based On NB-IOT

As one of the important parts of power transmission and distribution network,most of the power tower is in the wild environment,which is vulnerable to various natural reasons and human factors,resulting in tower tilt,deformation and even collapse,which seriously affects the operation safety and stability of the transmission network.At present,the state monitoring of power transmission towers in China mostly adopts manual periodic inspection,which is not only costly and inefficient,but also can not guarantee the accuracy.Therefore,it is difficult to timely discover and prevent the hidden dangers of power transmission towers in advance.With the rapid development of Internet of Things technology,The State Grid Corporation is paying more and more attention to the construction of ubiquitous power Internet of Things.It has become an irresistible trend to realize intelligent and information-based monitoring of transmission equipment.Therefore,this paper combined the NB-iot technology and designed a remote monitoring system of power tower status based on the NB-iot.Through the remote real-time monitoring and early warning of transmission tower tilt status and micro-meteorological environment,it can reduce the work intensity of inspection personnel and improve the inspection efficiency of transmission equipment.This article first compares the current mainstream long-distance wireless communication technology in detail,combines the actual application scenarios of the power tower status remote monitoring system,and selects the NB-IOT technology with the advantages of low power consumption,wide coverage and large connection as the wireless transmission method of this system,and then adopts Analyze the actual functional requirements of the system and complete the overall system design.The system uses the monitoring terminal to collect and upload the attitude information of the tower and the surrounding micro-meteorological information,the IoT cloud platform realizes the storage and forwarding of data,and the upper computer management system displays and processes the data.Secondly,the hardware and software design of the remote monitoring system for the status of the power tower has been completed.In hardware design,the monitoring terminal selects STM32L151C8T6 as the main control chip,and the wireless transmission module selects BC26.On this basis,the main control module peripheral circuit,communication module circuit,sensor data acquisition circuit and power supply module circuit are designed;The software part completes the terminal data collection and upload program design,the OneNET cloud platform access and configuration program design,and the upper computer management system development.Finally,the functions and performances of the system’s functional modules and the upper computer software were tested respectively.The test results show that the system can realize real-time monitoring of the attitude of the transmission tower and the micro-meteorological environment through the terminal and data transmission of the cloud platform,and realize the data visualization display and historical data query through the upper computer software and complete the alarm prompts of the preset conditions,which meets the design requirements.This solution provides a new method for remote monitoring of power transmission equipment and has certain application value.Figure[61]table[13]reference[62]...
