Development and verification of wireless torque sensor node for rotating shaft

Abstract

There are many torque measurement technologies at present, because the rotating shafting torque monitoring is very important. However, compared with the cost-effective strain measurement technology, there are signal transmission and power supply technology bottlenecks in the long-term monitoring of large shafting torque. In view of these technical bottlenecks, this paper designs a strain torque monitoring system based on wireless signal transmission technology and wireless inductive power supply technology. In this paper, the current torque measurement technology is analyzed. The design principle and technical characteristics of wireless torque sensor and wireless induction power supply device are developed. This paper is a complete long-term monitoring solution for shafting torque, which has a good referent value for relevant engineers and technicians.
