Problems solved by technology
The current display method is to draw the corresponding graph with the length of the optical cable as the horizontal axis and the sampling time as the vertical axis, and display it according to each sampling period, that is, the display device only displays the sampling data of one sampling period at a time, and cannot display Sampling data within a preset time period, if you need to obtain sampling data for a certain period of time, you need to obtain it from the database, which makes data acquisition inconvenient and the display is not intuitive enough

Embodiment Construction
[0012] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0013] Such as figure 1 As shown, the embodiment of the present invention provides a butterfly cable 1 with an environmental monitoring function, which is used for real-time monitoring of the parameters to be measured in the monitoring area (not shown), and sending monitoring signals to the monitoring system.
[0014] In the embodiment of the present invention, the butterfly cable 1 may be called a butterfly optical cable, also called an optical fiber sensor, and is laid at the monitoring area for real-time monitoring of the parameters to be measured in the monitoring area. The monitoring area can be any area suitable for monitoring by butterfly cables, such as tunnels, viaducts, gas pipelines, etc. In an exemplary embodiment, the butterfly cable of the...

The invention provides a butterfly cable with environmental monitoring function, which is used for real-time monitoring of the parameters to be measured in the monitoring area, and sends the monitoring signal to the monitoring system; the butterfly cable includes an outer sheath, a tight sleeve optical cable, and a strengthening member For loose-tube optical cables, two V-shaped tearing grooves are formed on both sides of the outer sheath; when the monitoring system receives abnormal data, it controls the display to enter the abnormal display mode: the display interface of the display is divided into the first A display area and a second display area, the first display area is used to display m images and corresponding time start points and time end points in m time periods, each time period includes N sampling periods, and the second display area is used for A video obtained by superimposing m images is displayed; each image is used to represent the relationship between the monitoring points on the butterfly cable and the corresponding monitoring signals within N preset sampling periods. The invention can visually display the monitoring signal in a sufficiently long time period on the display interface.
Description
technical field [0001] The invention relates to the field of sensing optical cables, in particular to a butterfly cable with an environment monitoring function. Background technique [0002] With the increasing demand for anti-electromagnetic interference, high temperature resistance, long-distance, distributed temperature and strain sensing optical fiber systems, due to the advantages of simultaneous measurement of temperature and strain, high precision, high spatial resolution and long distance, based on Bri The optical fiber sensing system for deep scattering analysis has been developed rapidly in the industry. Distributed optical fiber temperature and stress sensors are widely used in petrochemical energy, traffic tunnels, urban comprehensive pipe corridors, power cables, etc., for construction quality monitoring, long-term health monitoring, and fire alarms. The basic working principle of the optical fiber sensor is to send the optical signal from the light source to t...
