[0039] See also Figure 1-5 ,The present invention provides a technical solution: a safe step distance detection system, including a sensing module, an alarm module and a controller 12;

[0040] The sensing module includes a plurality of sensing units, which are evenly distributed and installed on the same side of the wall of the tunnel 11 along the extension direction of the tunnel 11 and connected in parallel to the controller 12;

[0041] The controller 12 is used to receive the sensing information transmitted by the sensing unit, process the sensing information according to a built-in preset program, and send instructions to the alarm module according to the processing result;

[0042] The alarm module includes a plurality of alarm units installed in the tunnel 11 corresponding to the plurality of sensing units one by one. The plurality of alarm units are connected in parallel to the controller 12 to receive instructions from the controller 12 and send prompt information to the outside according to the instructions.

[0043] The sensing unit is used to collect sensing information of the car driving at the corresponding position in the tunnel 11. By setting a plurality of sensing units in the tunnel 11 and evenly distributing them along the extension direction of the tunnel 11, a sensing area is formed in the extension direction of the tunnel 11 to synchronously sense whether there are cars passing at multiple positions in the section; the tunnel 11 length value corresponding to the sensing area is set to be equal to the minimum value of the safe driving distance corresponding to the speed limit condition of the tunnel 11, and two adjacent sensing units cannot sense the same car at the same time. After collecting the sensing information of the car driving, the sensing unit transmits the sensing information to the controller 12. The controller 12 processes the sensing information according to the built-in preset program to analyze and obtain the number and instantaneous position of the cars in the sensing area, and sends instructions to the plurality of alarm units according to the processing results. The plurality of alarm units simultaneously send warning information to remind the cars in the sensing area to maintain a safe driving distance and reduce the probability of traffic accidents.

[0044] During use, the detection system will encounter the following two states:

[0045] State 1: when there is no car driving in the sensing area, a car drives into the sensing area, and multiple sensing units send sensing information to the controller 12 in sequence as the car drives. When there is no vehicle driving into the rear of the car while the car is driving through the sensing area, since the controller 12 only receives one sensing information at the same time, the controller 12 analyzes and determines that there is only one car driving in the sensing area, that is, there is safe driving space in the front and rear directions of the car. Therefore, the controller 12 does not send a trigger instruction to the alarm unit, and the alarm unit does not issue a warning message.

[0046] State 2: When there is no car driving in the sensing area, a car drives into the sensing area, and multiple sensing units send sensing information to the controller 12 in sequence as the car drives. When a vehicle drives into the rear of the car while the car is driving through the sensing area, two of the sensing units sense the car driving information at the same time and transmit the sensing information to the controller 12. The controller 12 analyzes and determines that there are two cars driving in the sensing area, that is, the distance between the car and the rear car is reduced and has not reached the minimum value of the safe driving distance. Therefore, the controller 12 sends trigger instructions to multiple alarm units at the same time, and multiple alarm units send warning information at the same time to remind the vehicles behind the car to pay attention to avoid, and remind the rear car to slow down and maintain a safe driving distance.

[0047] In this embodiment: a mounting frame 2 is provided between the plurality of sensing units and the corresponding alarm units, and the plurality of mounting frames 2 are connected to a side wall of the tunnel 11;

[0048] The mounting frame 2 is provided with a first crossbar 21 for mounting a sensing unit and a second crossbar 22 for mounting an alarm unit. The first crossbar 21 is parallel to the road surface in the tunnel 11 and perpendicular to the second crossbar 22.

[0049] The second cross bar 22 extends in the same direction as the tunnel 11 , and the middle portions of the first cross bar 21 and the second cross bar 22 are fixedly connected to the mounting frame 2 .

[0050] By arranging the first crossbar 21 and the second crossbar 22 in two horizontal planes and being perpendicular to each other, the first crossbar 21 and the second crossbar 22 are staggered, so as to facilitate the installation of components such as the sensing unit and the alarm unit and reduce the probability of interference between the components.

[0051] A vertical axis wind turbine generator set 36 is installed at the top of each of the multiple mounting frames 2, and the blade rotation axis of the vertical axis wind turbine generator set 36 is perpendicular to the road surface of the tunnel 11. When a car passes through the mounting frame 2, the car pushes the air in the tunnel 11 to move in the extension direction of the tunnel 11 to form an airflow, and the airflow pushes the blades of the vertical axis wind turbine generator set 36 to rotate, so that the vertical axis wind turbine generator set 36 produces electricity. A battery 37 is fixedly installed at the bottom of each of the multiple mounting frames 2, and the battery 37 stores the electricity produced by the vertical axis wind turbine generator set 36 on the corresponding mounting frame 2, and the battery 37 is electrically connected to the sensing unit and the alarm unit on the corresponding mounting frame 2. The controller 12 is fixedly installed at the bottom of one of the mounting frames 2 and is electrically connected to the corresponding battery 37.

[0052] In this embodiment: a plurality of the mounting frames 2 are fixedly connected to a slider 23 in the middle, and a plurality of the sliders 23 are slidably matched with a slide rail 24;

[0053] The slide rail 24 extends in the same direction as the tunnel 11 and is fixedly installed on a side wall of the tunnel 11 .

[0054] By setting a slide rail 24 extending in the same direction as the tunnel 11, and fixing the slide rail 24 by driving an expansion bolt into a side wall of the tunnel 11, the slider 23 is slidably matched with the slide rail 24 to limit the free rotation of the mounting frame 2, so that the mounting frame 2 can slide with a single degree of freedom along the extension direction of the tunnel 11, so as to facilitate the control and adjustment of the distance between two adjacent mounting frames 2, adjust the length value of the tunnel 11 corresponding to the sensing area, that is, adjust the safe driving distance value that triggers the system to issue a warning message during the driving of the car.

[0055] The bottom end of the mounting frame 2 is pressed against the shoulder in the tunnel 11 , and the mounting frame 2 is supported by the shoulder, sharing the pressure on the slide rail 24 , so that the connection between the slider 23 and the slide rail 24 in the mounting frame 2 is stable.

[0056] In this embodiment: a winding roller 25 is sleeved outside the first cross bars 21 on the plurality of mounting frames 2 and is rotatably connected thereto. A measuring rope 26 is wound around the winding roller 25 , and one end of the measuring rope 26 is fixedly connected to the winding roller 25 .

[0057] A torsion spring is provided between the winding roller 25 and the first cross bar 21 , one end of the torsion spring is fixedly connected to the winding roller 25 , and the other end is fixedly connected to the first cross bar 21 , and the measuring rope 26 is wound around the winding roller 25 when the torsion spring is in a naturally stretched state.

[0058] By providing a measuring rope 26 , the distance between two adjacent mounting frames 2 can be measured and adjusted; by providing a winding roller 25 and a torsion spring, the measuring rope 26 can be quickly wound up, thereby improving the working efficiency of winding up the measuring rope 26 .

[0059] In this embodiment: the sensing unit is an infrared sensor 31, and the infrared sensor 31 is connected to one end of the first crossbar 21 facing the other side wall of the tunnel 11;

[0060] The multiple infrared sensors 31 on the multiple mounting frames 2 all emit infrared rays toward the other side wall in the tunnel 11 , and the infrared rays emitted by the multiple infrared sensors 31 are parallel.

[0061] In this embodiment, the infrared sensor 31 is rotatably connected to one end of the first crossbar 21 , and the plane of the rotation track is parallel to the road surface in the tunnel 11 .

[0062] By rotating the infrared ray emission direction of the infrared sensor 31 toward one end of the tunnel 11 entrance, part of the infrared ray emitted by the infrared sensor 31 is emitted out of the tunnel 11 entrance, so as to sense and detect whether there is a car passing by outside the tunnel 11 entrance, so as to detect whether there is a car within the safe driving distance in front of the car about to enter the tunnel 11, and issue a corresponding warning message. By rotating the infrared sensor 31 and the first cross bar 21, the infrared ray emission direction of the infrared sensor 31 can be adjusted, so as to adjust the deflection angle of the infrared sensor 31 according to the speed limit standard of the tunnel 11.

[0063] In this embodiment: an absorption plate 32 for absorbing infrared rays is provided on one side of the mounting frame 2. The absorption plate 32 extends in the same direction as the tunnel 11 and is fixedly installed on the other side wall of the tunnel 11. The infrared rays emitted by the multiple infrared sensors 31 are all irradiated on the absorption plate 32.

[0064] The surface of the absorption plate 32 is coated with an infrared absorber. When the infrared rays emitted by the infrared sensor 31 irradiate the absorption plate 32, the infrared absorber absorbs the infrared rays, reducing the probability of the infrared rays being reflected and received by the infrared sensor 31, so as to improve the accuracy of the information sensed by the infrared sensor 31.

[0065] In this embodiment: one end of each of the plurality of second cross bars 22 is fixedly connected with a WI FI transceiver module 33, and each of the plurality of WI FI transceiver modules 33 on the second cross bars 22 is electrically connected to a corresponding sensing unit and a corresponding alarm unit;

[0066] The controller 12 is also electrically connected to a WI FI transceiver module 33 , and the WI FI transceiver modules 33 on the plurality of second crossbars 22 are all communicatively connected to the WI FI transceiver module 33 on the controller 12 .

[0067] The WI FI transceiver module 33 on the mounting frame 2 and the WI FI transceiver module 33 on the controller 12 are wirelessly connected to improve the freedom of the mounting frame 2 and facilitate the movement of the mounting frame 2.

[0068] In this embodiment, the alarm unit includes a speaker 34 , which is fixedly connected to the second crossbar 22 , and the speaker 34 is electrically connected to the WI FI transceiver module 33 on the corresponding second crossbar 22 .

[0069] By arranging speakers 34 on multiple mounting frames 2 and controlling the multiple speakers 34 to emit warning sounds simultaneously through the controller 12, warning sounds are emitted at multiple points in the sensing area in the direction of the tunnel 11, warning all cars in the sensing area, and reminding the drivers in the cars auditorily, thereby increasing the drivers' attention and reducing the probability of traffic accidents.

[0070] In this embodiment, the alarm unit further includes a warning light 35 , which is fixedly connected to the second cross bar 22 , and is connected in series with the corresponding speaker 34 .

[0071] By arranging warning lights 35 on multiple mounting frames 2 and controlling multiple warning lights 35 to emit warning lights 35 at the same time through the controller 12, warning lights 35 are emitted at multiple points in the sensing area in the direction of the tunnel 11, so as to warn all cars in the sensing area and visually remind the drivers in the cars, thereby further reducing the probability of traffic accidents. At the same time, multiple warning lights 35 form a guide line for the tunnel 11 to assist the car in moving forward.

[0072] Among them, the specific model of the infrared sensor 31 is GP2Y0A710K, and the specific model of the WI FI transceiver module is CC3100.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
