The invention relates to a test method for the environmental adaptability of an optical fiber sensing system. The test method includes three parts: a hardware connection stage, a test preparation stage and a test stage: the hardware connection stage includes: preparing a temperature and humidity environment test box, and a prototype to be tested , industrial computer, double-layer shielded network cable, power cord and optical fiber disk; the test preparation stage includes: starting the prototype to be tested and the industrial computer and making the network communication between the two normal, and then opening the system control software in the industrial computer to start monitoring the operation of the prototype to be tested status; the test phase includes setting various temperatures and operations and monitoring test results to draw monitoring conclusions. The test method of the present invention selects the most severe working and operating temperature and humidity environment of the product, and allows the product to operate in its extreme environment, thereby providing assistance for device selection and design improvement. During the test, the product is run online and monitored in real time , by comparing the conditions and data before the test, under the high temperature test, under the low temperature test and under the damp heat test.
