Embodiment Construction
[0033] The specific structure and embodiments of the present invention will be further described below with reference to the accompanying drawings, but the protection scope of the present invention should not be limited by this.
[0034] like figure 1 and figure 2As shown, a real-time monitoring device for cable force includes a force measuring ring 3 and 8 long gauge fiber grating strain sensors 13. The force measuring ring 3 is a hollow ring, which includes a first force bearing ring 10, a second The force-receiving ring 11 and the side wall 15 are provided with axial grooves on the side wall 15 to form a narrow column 12 for installing the sensor. In this embodiment, the number of narrow columns 12 is 8, and each narrow column 12 is installed on the One long-gauge length fiber grating strain sensor 13, generally more than four long-gauge length fiber grating strain sensors 13 can obtain stable data. The long gauge length fiber grating strain sensor 13 is firmly connected...
