[0037] Figure 1 The optical sensing communication terminal of the utility model is used in the optical sensing communication system. The optical sensing communication system includes an optical sensing communication terminal 100, an optical cable 200, and a base station 300. In some embodiments, the optical sensing communication system also includes a sensor 400.

[0038] The optical sensing communication system including the optical sensing communication terminal 100 can be used in underground environment monitoring scenarios, and the sensor 400 connected to the optical sensing communication terminal 100 for communication is, for example, a gas concentration sensor, a harmful gas concentration sensor, a water level sensor, a liquid flow rate sensor, a gas leakage sensor, a liquid leakage sensor, a structural deformation sensor, etc. For example, the optical sensing communication system is used to monitor environmental facilities such as power pipe corridors, gas pipelines, coal mines, gas wells, rainwater wells, sewage pipes, subway tunnels, etc., to achieve long-distance monitoring of gas concentration, water level, flow rate and other information in harsh environments.

[0039] The optical sensing communication system including the optical sensing communication terminal 100 can be used in emergency rescue scenarios. For example, when an accident occurs in harsh construction environments such as mines, subways, tunnels, and seabeds, trapped people can communicate with a remote command center through voice through the optical sensing communication terminal 100 hung on the optical cable 200. The base station 300 analyzes information such as distance, location, number of people, and voice. The command center visualizes the location information and assists in deploying rescue plans.

[0040] Figure 2 , Figure 3 It is a three-dimensional exploded schematic diagram of different viewing angles of an embodiment of an optical sensing communication terminal of the utility model. The optical sensing communication terminal 100 includes a shell assembly 110 and a vibration assembly 120. The shell assembly 110 includes a first shell 111, a second shell 112, a first device cavity 114 and a sealed cavity 115. The first shell 111 and the second shell 112 are detachably connected, and the first shell 111 and the second shell 112 are enclosed as a first device cavity 114 and a sealed cavity 115. The sealed cavity 115 is arranged on opposite sides of the first device cavity 114 along the first direction X. When the first shell 111 and the second shell 112 are connected, they can clamp the optical cable 200, and the optical cable 200 inserted between the first shell 111 and the second shell 112 extends along the first direction X and passes through the first device cavity 114 and the sealed cavity 115. At least one of the first shell 111 and the second shell 112 is provided with a first through hole H1 connecting from its outer surface to the sealing cavity 115 , and external liquid glue can enter the sealing cavity 115 through the first through hole H1 and transform into a solid sealant filling the sealing cavity 115 after solidification.

[0041] The vibration assembly 120 is disposed in the first device cavity 114, and the vibration assembly 120 is used to abut against the optical cable 200 to apply vibration to the optical cable 200. The number of the vibration assembly 120 can be single or more than two. Exemplarily, when there are more than two vibration assemblies 120, the more than two vibration assemblies 120 perform the same vibration motion based on the same vibration signal.

[0042] The optical sensing communication terminal 100 is connected to the sensor 400 for communication, thereby generating a corresponding vibration signal according to the sensing signal of the sensor 400. The vibration component 120 can vibrate the optical cable 200 according to the vibration signal. At this time, the base station 300 connected to the optical cable 200 sends a laser signal. The vibration of the optical cable 200 by the vibration component 120 enables the forward optical signal in the optical cable 200 to generate reverse photons corresponding to the vibration signal, that is, reflected optical signals. The base station 300 collects the reflected optical signal and can analyze and obtain the corresponding vibration signal, thereby realizing the transmission and demodulation of the vibration signal and completing the sensing communication function of the optical cable 200.

[0043] According to the optical sensing communication terminal 100 of the embodiment of the utility model, the optical sensing communication terminal 100 includes a housing assembly 110 and a vibration assembly 120. The housing assembly 110 includes a first housing 111, a second housing 112, a first device cavity 114 and a sealing cavity 115. The vibration assembly 120 is arranged in the first device cavity 114, and the sealing cavity 115 is arranged on opposite sides of the first device cavity 114 along the first direction X. At least one of the first housing 111 and the second housing 112 is provided with a first through hole H1 connected from its outer surface to the sealing cavity 115, and the external liquid glue can enter the sealing cavity 115 through the first through hole H1 and transform into a solid sealant filling the sealing cavity 115 after solidification. The solid sealant seals the gap between the optical cable 200 and the housing assembly 110 at both ends outside the first device cavity 114, thereby improving the sealing performance of the first device cavity 114, and facilitating the optical sensing communication terminal 100 to adapt to a more severe detection environment. The optical sensing communication terminal 100 of the embodiment of the utility model has a prefabricated sealing cavity 115 in the shell assembly 110. After the shell assembly 110 and the optical cable 200 are assembled, liquid glue is injected into the sealing cavity 115 through the first through hole H1. After the liquid glue is solidified, a high-reliability sealing operation can be completed, thereby facilitating the improvement of the assembly connection between the optical sensing communication terminal 100 and the optical cable 200.

By providing the second sealing ring, the sealing effect of the first device cavity 114 is further improved at the connection interface between the first shell 111 and the second shell 112.

[0054] In some embodiments, the sealing groove 116 is provided through the sealing cavity 115, and the solid sealing member obtained after the liquid glue is cured in the sealing cavity 115 is connected to the second sealing ring as a whole.
