The bridge viewing method is to use the sensor to perceive the physical quantity of the measured object, convert the perception signal into the output of the telecommunication signal according to the fixed law, collect the electrical signal of the sensor with the active collection equipment, transmit the data to the remote server by the wireless data transmission module, complete the processing, storage, display recording, analysis and control of the information.
When the bridge is viewed, the stress, displacement, cracks, temperature and humidity, acceleration and other aspects are often checked, and the parameters obtained can be understood in real time to understand the application of the bridge and respond to various abnormal situations. Here is a brief explanation of how to use sensors to detect stress and do a good job of monitoring data transmission.
Stress detection sensor: converts the physical stress of the bridge into an electrical signal, and the output electrical signal has two kinds of analog electronic signals and data electronic signals, which are determined by the sensor in detail. Embedded concrete strain gauge can be selected, the effect is good, the defect is the device and the protection is troublesome, can also use the earth pressure box, the device is simple and convenient, the defect is that the detected parameters are incorrect, but the stress of the bridge can be roughly reflected by the single-point settlement gauge and other stress detection sensors can also use other stress detection sensors such as single-point settler.
Among them, the stress measurement sensors commonly used in bridge monitoring are: force sensors, steel bar stress sensors, bow strain sensors, resistive displacement sensors, etc.

How to use angle sensors to measure torque – Turck
It is difficult to measure torque on a continuously rolling axis, and there are several ways to do it. The most common method is to derive the torque from the energy required by the rolling shaft. In general, this means measuring the current of the motor that drives the rolling shaft. Although this is simple but inaccurate, it is caused by ...
