Problems solved by technology

[0003] The underground comprehensive utility gallery needs to integrate municipal pipelines such as electricity, communications, radio and television, water supply, drainage, heat, and gas in a limited closed space underground. Although it is an effective way to solve various problems in modern urban construction, it is also There is a huge security risk
1) Once the leakage of the concentratedly laid gas pipeline occurs, when the dangerous gas such as methane and carbon monoxide reaches a certain concentration, it is very likely to cause a fire or even cause an explosion, resulting in disastrous consequences
2) The temperature of the large-load power transmission cable increases due to load changes or various faults, which will lead to overheating of the cable or aging of the insulation, resulting in electric sparks, which may easily lead to fire or explosion

Embodiment 1

[0029] This embodiment is a further explanation and description of the method for measuring the temperature of an urban comprehensive utility gallery, but it does not constitute any limitation to the present invention.

[0030] In this embodiment, two sections of sensing optical cables (with lengths of L respectively) in three adjacent data collection points 1 , L 2 m) as the research object, aiming at the distance from the first data collection point to process the endpoint length X 1 The position of the meter is the measurement point, and the distance from the second data collection point to the processing end point is L 1 -X 1 The position of meters, for the distance from the second data collection point processing endpoint length X 2 The position of the meter is the measurement point, and the length from the third data collection point to the processing endpoint is L 2 -X 2 m position. It is assumed that within a certain period of time t, the backscattered anti-Stoke...

Abstract

The invention discloses a comprehensive pipe gallery temperature measuring method, belongs to the technical field of electronic information, and relates to a photoelectric sensing technology. The temperature measurement method of the distributed optical fiber Raman temperature sensing system adopting a cloud computing model is applied to the temperature measurement of the comprehensive pipe gallery, and the stability of the temperature measurement of the comprehensive pipe gallery and the rapidity of sensing the temperature by one comprehensive pipe gallery can be improved. A novel distributed optical fiber sensing network is formed, and an innovative means is provided for a comprehensive pipe gallery safety risk assessment model.

Description

technical field [0001] The invention belongs to the technical field of electronic information and relates to a photoelectric sensing technology, in particular to a method for measuring the temperature of a comprehensive pipe gallery. Background technique [0002] Urban underground comprehensive pipe corridor refers to the public tunnel used to lay municipal pipelines such as electric power, communication, radio and television, water supply, drainage, heat, gas, etc. under the city. As an effective way to solve the problems of urban space and municipal pipe network, it represents The inevitable direction of the development of modern urban infrastructure. The urban underground comprehensive pipe gallery has completely solved the problems of modern urban construction such as "road zippers" and "air spider webs". It is an important step in the construction of innovative urban infrastructure. The city's comprehensive carrying capacity is the only way for future urban constructio...
