Probe into Multiple State Information Monitoring System of High Voltage Transmission Lines Based on 3G Internet of Things

A kind of multiple state infnrmation monitoring system of high voltage transmission line integrating digital video and operation parameters monitoring hased on 3G inlernet of things is developed. In this system, the image signal and operation information acquired by sensors is digitized and transmitted to muhiple mobile access terminal through 3G wireless communication networks to achieve the muhiple sate monitoring of high voltage transmission line. The system is divided into three layers, namely data collection terminal layer, 3G transpnrl layer, expert analysis and control system layer. 3G wireless data transmission technology based on adaptive bandwidth method is adopted in 3G transport layer. By using this kind of technology, according to the signal quality, the network can be automatically switched between three networks, which include China Telecom, China Unicorn and China Mobile 3G network. Ae, cording to the bandwidth of multiple links, the bandwidth of audio and video data and operation status data is automatically assigned. This method greatly increases the bandwidth and quality in video and audio transmission, and ensures the stahility, reliability and real-time of the mnhiple state monitoring system.
