Abstract
The invention belongs to the field of force measuring sensors and discloses an embedded tension pressure monitoring device. The monitoring device includes an embedded stress sensor and a collector. The embedded stress sensor is installed in the tapered hole of the measured structure. When the measured structure is stressed, the tapered hole is deformed, which in turn causes the deformation of the embedded stress sensor, and an electrical signal is output through the force sensitive resistor. The collector completes the power supply to the embedded stress sensor and the acquisition, processing and recording of sensor signals to realize real-time monitoring of tension and pressure. Compared with the current tension pressure measurement device, the present invention reduces maintenance cost, improves measurement adaptability, realizes real-time monitoring of tension pressure, and can reflect the working state of the component under test when it is in service.
Description
technical field [0001] The invention belongs to the field of force measuring sensors, in particular to an embedded tension pressure monitoring device. Background technique [0002] With the development of industrial automation and intelligence, the application of stress measurement is becoming more and more extensive. For the stress measurement of some key components, its control parameters can be obtained, and then automatic control can be realized. In engineering equipment, such as the automatic control of the jib, for heavy objects of different masses and different lifting speeds, it is necessary to control the magnitude of the lifting force, so it is necessary to measure the force of the jib; In transportation, for example, in the transition process of the switch driven by the switch machine, if the conversion force exceeds the normal range, it will endanger the driving safety. Measuring the conversion force of the switch machine is beneficial to improve the stability an...
