Title:
BULGE SELF-SENSING PLATE TYPE SUPPORT, MANUFACTURING METHOD, MONITORING SYSTEM AND MONITORING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/067233
Kind Code:
A1
Abstract:
A monitoring method for a monitoring system of a bulge self-sensing plate type support. The plate type support is based on a circular plate type support (1), spirally wound strain sensing optical fibers (2) are arranged and fixed on the annular side face of the circular plate type support (1). The monitoring system is based on the plate type support, and by means of a transmission optical fiber (3), the strain sensing optical fibers (2) of a plurality of plate type supports (1) and an optical fiber signal analysis device (4) are connected in series to form a circuit. The monitoring method comprises: B1, measuring an optical power loss value; B2, calculating a bulging strain value of a circular plate type support (1); B3, repeatedly calculating to obtain all bulging strain values; and B4, determining the health condition of the support according to the change in the bulging strain value.
