Research on Multi-Sensor Data Acquisition and Transmission Technology based on Ad Hoc Network Technology

In view of the growing requirements for online monitoring of water level, gas, temperature and humidity, partial discharge, etc. in buried cables, under the unified architecture of the Internet of Things for power transmission and transformation equipment of State Grid Corporation of China, this paper has carried out research and application of panoramic sensing technology for buried cables based on wireless sensor networks, breaking through the key technologies of directional coverage enhancement of wireless signals and flexible topology networking of distributed multi optimized deployment networks, In order to solve the problems of limited coverage and low networking efficiency when the universal wireless sensor network is applied to the long and narrow buried cable environment, in-depth research is made on the requirements and characteristics of sensor data transmission in the buried environment, customized low-power wireless sensor network system is developed, and the multi parameter comprehensive monitoring and panoramic perception pilot application of buried cables are carried out, so as to achieve unified access and data fusion analysis of various environment and status sensors, And provide low-cost, cost-effective solutions. By building a set of software and hardware system for online real-time monitoring+efficient routing and positioning of buried cables, the cost of operation and maintenance of buried cables can be greatly reduced, the efficiency of operation and maintenance can be improved, and the safety and reliability of cable operation can be improved.
