Problems solved by technology

[0004] In the actual operation process, due to the suddenness, irregularity and unpredictability of the occurrence of the tunnel wall falling off, coupled with the limited staff, it is impossible to monitor the falling objects in the tunnel in real time. Ignore the falling objects on the wall in some tunnels, which affects the safe operation of the train

Embodiment 1

[0080] In order to realize real-time monitoring of the falling objects in the tunnel, and feedback the situation of the wall falling in the tunnel to the staff, so that the staff can deal with the monitoring results in time, prevent the occurrence of danger, and ensure the operation of the train. Safety. see figure 1 , this embodiment provides a monitoring and alarm system for falling objects in a tunnel, including: a radar monitoring unit 30, a video monitoring unit 50 and a system control unit 40;

[0081] The system control unit 40 is respectively connected with the video monitoring unit 50 and the radar monitoring unit 30;

[0082] The radar monitoring unit 30 is used to detect the falling objects in the tunnel, and when the falling objects appear in the tunnel, the coordinate information of the falling objects in the tunnel is sent to the system control unit 40;

[0083] The video monitoring unit 50 is used to obtain the video data of the coordinate information in the t...

Embodiment 2

[0137] see image 3 , the embodiment of the present invention also provides a method for monitoring and alarming falling objects in a tunnel using the monitoring and alarming system for falling objects in a tunnel in the above-mentioned embodiment, and the method includes the following steps:

[0138] Step S302, when a falling object appears in the tunnel, obtain the coordinate information of the falling object in the tunnel.

[0139] In step S304, the obtained coordinate information of the dropped object in the tunnel is processed, and video data of the scene of the dropped object in the tunnel is obtained according to the obtained processing result.

[0140] Step S306, displaying the acquired video data of the falling object scene in the tunnel to the user.

[0141] Wherein, when there is a falling object in the tunnel, obtaining the coordinate information of the falling object in the tunnel includes the following steps (1) to (2):

[0142] (1) When there is a falling obje...

Abstract

The invention provides a monitoring and alarming system and method for a falling object in a tunnel, and belongs to the field of electronic monitoring. The monitoring and alarming system comprises a radar monitoring unit, a video monitoring unit and a system control unit. The radar monitoring unit is used for detecting a falling object in the tunnel and sending coordinate information of the falling object in the tunnel to the system control unit when the falling object appears in the tunnel. The video monitoring unit is used for acquiring video data of the coordinate information in the tunnel according to the coordinate information provided by the system control unit. The system control unit is used for receiving real-time monitoring data of the radar monitoring unit and the video monitoring unit and analyzing and processing the monitoring data. Compared with the prior art where it is required that a worker tours a tunnel to find and remove a falling object, the detection system can monitor the environment in the tunnel in real time, accurately find the falling object in time and feed the information back to a worker for timely handling, and thus the running safety of a train is guaranteed.

Description

technical field [0001] The invention relates to the field of monitoring systems in tunnels, in particular to a monitoring and alarming system and method for falling objects in tunnels. Background technique [0002] At present, the construction of high-speed railways is developing rapidly, and the high-speed railway lines are all over the country. A large number of tunnel constructions have also been carried out. The phenomenon of foreign objects encroaching on the walls caused by falling objects in the tunnels often occurs. Therefore, in order to ensure the normal operation of the train, the monitoring and treatment of the falling objects in the tunnel has received extensive attention. [0003] In the related art, the monitoring of the falling objects in the tunnel usually requires staff to patrol, find the falling wall in time, and then clean it up to ensure the normal operation of the train and avoid the occurrence of danger. [0004] In the actual operation process, due ...
