Description

Technical Field

[0001] This utility model relates to the technical field of tunnel safety early warning, and in particular to a tunnel environment monitoring device for long-distance operation. Background Technology

[0002] Tunnels are an important part of modern transportation. They not only solve the problem of highway and railway detours but also provide travelers with a different driving experience. Tunnels are built by carving through mountains and have a relatively enclosed driving environment. There are various data acquisition units inside tunnels to monitor tunnel parameters. The lights in tunnels are usually kept on for a long time, but keeping the lights on for a long time wastes a lot of electricity. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a tunnel environment monitoring device for long distances, which solves the problem of excessive power waste caused by the long-term lighting in tunnels.

[0004] To solve the above-mentioned technical problems, this utility model provides a tunnel environment monitoring device for long distances, including a signal acquisition unit, a controller, a communication transmission unit, a remote monitoring terminal, and a lighting lamp. The signal acquisition unit, the communication transmission unit, and the remote monitoring terminal are electrically connected to the controller. The signal acquisition unit includes a human body sensor for detecting humans and a noise sensor for detecting the intensity of noise from passing vehicles. The controller turns on the lighting lamp based on the detection signal from the human body sensor and the intensity of noise from the noise sensor.

[0005] In the preferred embodiment, the communication transmission unit includes a 4G module and a 4G network, and the controller sends the detected signals to the remote monitoring terminal through the communication transmission unit.

[0006] In a preferred embodiment, the signal acquisition unit further includes a temperature and humidity sensor for detecting temperature and humidity inside the tunnel and a dust sensor for detecting dust inside the tunnel.

[0007] In a preferred embodiment, the controller uses a DSP28335 main control chip; the temperature and humidity sensor uses a DHT11 type temperature and humidity sensor; and the dust concentration detector uses a PC3AS type dust concentration detector.

[0008] In the preferred embodiment, the human body sensor, humidity sensor, and dust sensor are respectively installed in the tunnel entrance section, middle section, and tunnel exit section of the tunnel wall.

[0009] In the preferred embodiment, noise sensors are respectively installed at the tunnel entrance and tunnel exit sections of the tunnel wall.

[0010] The beneficial effects of this utility model are: when a person is detected in the tunnel by the human body sensor, the lighting can be turned on. When the noise from the noise sensor gets louder and louder, it is determined that a vehicle is about to pass through the tunnel. At this time, the controller turns on the lighting to facilitate the vehicle's passage. At other times, the lighting can be turned off, thereby avoiding the waste of power resources. Attached Figure Description

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0012] Figure 1 This is an electrical structure connection diagram of an embodiment of the present utility model. Detailed Implementation

[0013] Please refer to the figure. This application provides a technical solution: a tunnel environment monitoring device for long distances, including a signal acquisition unit, a controller, a communication transmission unit, a remote monitoring terminal, and a lighting lamp. The signal acquisition unit, the communication transmission unit, and the remote monitoring terminal are electrically connected to the controller. The signal acquisition unit includes a human body sensor for detecting humans and a noise sensor for detecting the intensity of noise from passing vehicles. The controller turns on the lighting lamp based on the detection signal from the human body sensor and the intensity of noise from the noise sensor.

[0014] Human body sensors mainly use infrared detection to determine whether there is a person present, and are well-known products; noise sensors are also well-known products.

[0015] When the human body sensor detects someone in the tunnel, it can control the lights to be turned on. When the noise sensor detects increasing noise, it indicates that a vehicle is about to pass through the tunnel, and the controller will turn on the lights to facilitate the vehicle's passage. At other times, the lights can be turned off to avoid wasting power resources.

[0016] In the preferred embodiment, the communication transmission unit includes a 4G module and a 4G network, and the controller sends the detected signals to the remote monitoring terminal through the communication transmission unit.

[0017] This allows for remote monitoring of the situation inside the tunnel via 4G modules and 4G networks.

[0018] In a preferred embodiment, the signal acquisition unit further includes a temperature and humidity sensor for detecting temperature and humidity inside the tunnel and a dust sensor for detecting dust inside the tunnel.

[0019] Temperature and humidity sensors monitor for water seepage inside the tunnel, while dust sensors monitor the dust levels inside the tunnel. The data is then transmitted to a remote monitoring terminal via a 4G module for back-end staff to process, thus enabling remote monitoring.

[0020] In a preferred embodiment, the controller uses a DSP28335 main control chip; the temperature and humidity sensor uses a DHT11 type temperature and humidity sensor; and the dust concentration detector uses a PC3AS type dust concentration detector.

[0021] In the preferred embodiment, the human body sensor, humidity sensor, and dust sensor are respectively installed in the tunnel entrance section, middle section, and tunnel exit section of the tunnel wall.

[0022] In the preferred embodiment, noise sensors are respectively installed at the tunnel entrance and tunnel exit sections of the tunnel wall.

That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
