Problems solved by technology

The existing wireless strain test technology is developing rapidly. At present, the main existence is the wireless resistance strain test system, but the biggest problem of the resistance strain test technology is the unstable performance. Long-term monitoring, especially in the outdoor working environment, is easy to cause the test data drift

[0006] The existing wireless vibrating wire strain collection system adopts the basic point-to-point wireless form. All sensors are still connected to the only collection device by wires, and the collection device transmits the data to the receiving base station through wireless signals. The transmission method is simple. , there is no networking, the flexibility is poor, and such products generally consume a lot of energy and need mains power supply, so wireless products still rely heavily on wires, and the improvement from traditional wired vibrating strain equipment is not obvious

At present, there is no new strain test system that integrates advanced wireless communication technology and stable sensing technology in the market
