Title:
TEMPERATURE SENSING APPARATUS AND METHOD, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/092980
Kind Code:
A1
Abstract:
A temperature sensing apparatus (10) and method, and a storage medium. The temperature sensing apparatus (10) should be configured to be a converter system, which comprises at least one converter component. The apparatus (10) comprises: a sensing optical fiber (102) and a control unit (101). The control unit (101) stores the correspondence between temperature information of a position in which each unit from among at least one unit in the sensing optical fiber (102), which is calibrated, and a corresponding converter component. The sensing optical fiber (102) is connected to the control unit (101) by means of an optical fiber connector. The control unit (101) is configured to send a first optical signal to the sensing optical fiber (102), and receive a second optical signal at a first position of a first unit after the first optical signal is scattered by means of the sensing optical fiber (102). The first unit is any one unit among the at least one unit in the sensing optical fiber (102). Temperature information of a converter component corresponding to the first position in which the first unit is located is determined on the basis of the correspondence and the second optical signal.
