A test method for environmental adaptability of optical fiber sensing system

Abstract

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.

Description

technical field [0001] The invention relates to product reliability engineering technology, which is based on international and domestic industry standards, and is used for a reliability detection scheme for product development and design conforming to technical specifications. Background technique [0002] Reliability engineering started in the early 1950s from the research on the reliability of electronic equipment in the United States. In 1957, the U.S. Department of Defense established the Ad Hoc Committee on Missile Reliability, and the Institute of Electrical and Electronics Engineers (I.E.E.E.) regularly published Reliability Transactions. It was not until the 1960s that the reliability technology of electronic equipment was gradually extended to various industries such as machinery and construction. In 1965, the International Electronic Technology Committee (IEC) established the Reliability Technical Committee to coordinate reliability terms and definitions, reliabi...

Problems solved by technology

In the current general method, either different samples are used to carry out environmental tests under different conditions, or the environmental tests under different conditions are incoherently carried out with the same sample, which is a non-combined test, which reduces the severity of the test and makes it difficult to find component failures. and design defects; or set environmental test conditions according to the requirements of specific standards or technical specifications, instead of simulating the extreme conditions during the use of the product, it is difficult to understand and grasp the use conditions and problems within the entire range of environmental conditions of the product's nominal ; or the product is not powered on or monitored online, and the status and problems of the product during the entire environmental test process cannot be monitored throughout the process, and the limit value of the product under these conditions cannot be understood, and the problems that may be found cannot be predicted. Or mastered enough to not be able to find the source of the problem
