Description

Technical Field

[0001] The present invention relates to the technical field of intelligent transportation, and particularly relates to a tunnel accident warning and guiding system and method. Background Art

[0002] In the prior art, once an accident occurs in a tunnel, safety cones are generally used to surround the accident location. However, due to the relatively dim light in the tunnel, when an accident such as a car crash occurs, using safety cones to surround the accident location has the following two problems:

[0003] First, the visibility of safety cones in the tunnel is not high, and it is not intuitive to see the placement position of the safety cones in the tunnel. Vehicles are likely to collide with the safety cones, resulting in secondary accidents.

[0004] Second, different from the external highway, the width of the tunnel is small, the wind generated by the passing vehicles is large, and the safety cones are placed independently. The airflow generated by the passing vehicles is likely to blow the safety cones crooked or even down. Once one or several safety cones are displaced or toppled, the warning effect will be seriously affected.

[0005] For example, a multi-purpose safety cone used in a highway tunnel with the application number 2022205839573 can be used as a temporary warning device and a linear guiding sign, but it is used alone and cannot well enable the drivers of the oncoming vehicles to see the warning area. Summary of the Invention

[0006] To solve the above technical problems, the present invention provides a tunnel accident warning and guiding system and method. Through the first wire, not only the effect of transmitting electric energy is achieved, but also all the guiding mechanisms are connected into a whole to improve its stability; through the projection modules of several guiding mechanisms, a rectangular light band is projected on the ground to form a fully enclosed or semi-enclosed warning area, improving the warning effect.

[0007] The present invention adopts the following technical solutions:

[0008] A tunnel accident warning and guiding system includes a number of guiding mechanisms. Each guiding mechanism includes: a lower cone with a battery installation cavity inside, a first installation groove on the surface, and a connection port connected to the internal circuit of the guiding mechanism; an upper cone detachably arranged on the lower cone, with a second installation groove inside and an outlet connected to the second installation groove on the surface; an automatic wire winder located in the second installation groove, including a first wire with one end connected to the power supply and the other end extending out from the outlet; a projection assembly with one end rotatably fitted in the first installation groove, the other end having a projection module capable of projecting a rectangular light band on the ground, and a signal transmitter on one side and a signal receiver on the other side; the guiding mechanisms are connected to form an integral structure through the first wire and the connection port for power transmission; the rectangular light bands projected by the projection modules of a number of guiding mechanisms on the ground form a fully enclosed or semi-enclosed warning area.

[0009] Adjacent guiding mechanisms are connected to form an integral structure through the first wire and the connection port arranged in the upper cone for power transmission. Through the first wire, not only the effect of transmitting power is achieved, but also all guiding mechanisms are connected into an integral whole to improve their stability; the rectangular light bands projected by the projection modules of a number of guiding mechanisms on the ground form a fully enclosed or semi-enclosed warning area to improve the warning effect.

[0010] Preferably, at least one battery is provided in the lower cone of the guiding mechanism; in fact, as long as there is a battery in one guiding mechanism, power supply can be realized without carrying too many batteries.

[0011] Preferably, after the upper cone is installed on the lower cone, the circuit in the upper cone is connected to the circuit in the lower cone. By adopting a split-circuit design, once a part of the structure is damaged, it is not necessary to replace the whole; at the same time, before the upper cone is installed on the lower cone, the guiding mechanism as a whole is not powered on, which is safer.

[0012] Preferably, a third installation groove is provided at the top of the upper cone, and a warning light is installed in the third installation groove to improve the warning effect.

[0013] Preferably, a number of guiding lights are provided on the first wire, and a regular isolation warning pattern is formed on the integral structure formed by the connected guiding mechanisms; the isolation warning pattern is a number of obliquely arranged patterns, which cooperate with the rectangular warning area on the ground to improve the warning effect.

[0014] A tunnel accident warning and guiding method includes the following steps:

[0015] S100: Place a number of guiding mechanisms in the accident area in the tunnel and enclose a fully enclosed or semi-enclosed area.

[0016] S200: Connect the first wire of the induction mechanism to the connection port of the next induction mechanism to form an integral structure and conduct power transmission.

[0017] S300: The rectangular light bands projected by the projection modules of several induction mechanisms on the ground form a fully enclosed or semi-enclosed warning area.

[0018] Preferably, a storage battery is installed on one of the induction mechanisms. It only needs one induction mechanism to have a storage battery to achieve power supply, without the need to carry too many storage batteries.

[0019] Preferably, in the said S300, the signal emitted by the signal transmitter of one induction mechanism is received by the signal receiver of the adjacent induction mechanism. Because the vehicles in the tunnel will vibrate to a certain extent during driving, the projection components on the induction mechanism may deflect due to vibration. The signal transmitter and the signal receiver are used in cooperation to detect whether the current projection component is in place.

[0020] Preferably, in the said S300, once one or more of the projection components deflect, the projection components swing up and down reciprocally until the signal emitted by the signal transmitter of the induction mechanism is received by the signal receiver of the adjacent induction mechanism or the signal receiver of the induction mechanism receives the signal emitted by the signal transmitter of the adjacent induction mechanism. The projection components can be automatically adjusted according to the actual situation.

[0021] Preferably, several induction mechanisms enclose a rectangle, the projection modules are arranged obliquely downward, and the projection on the ground forms an outward-expanded rectangular warning area.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] 1. The present invention provides a tunnel accident warning and induction system. The induction mechanisms are connected to form an integral structure and conduct power transmission through the first wire and the connection port arranged in the upper cone. Through the first wire, not only the effect of transmitting power is achieved, but also all the induction mechanisms are connected into a whole to improve their stability; the rectangular light bands projected by the projection modules of several induction mechanisms on the ground form a fully enclosed or semi-enclosed warning area to improve the warning effect.

[0024] 2. The present invention also provides a tunnel accident warning and induction method. When an accident occurs, an outward-expanded rectangular warning area can be formed on the ground through several obliquely downward arranged projection modules; and the projection components can be automatically adjusted according to the actual situation and cooperate with the projection components of other induction mechanisms.

Specific embodiments

[0038] In order to facilitate the understanding of the technical solution of the present invention, the following is a detailed description in combination with the accompanying drawings and specific embodiments.

[0039] Embodiment 1

[0040] As Figures 1-12 shown, a tunnel accident warning and induction system includes a plurality of induction mechanisms, and the induction mechanism includes:

[0041] The lower cone 1 is internally provided with a battery installation cavity 11, and its surface is provided with a first installation groove 12 and a connection port 13 connected to the internal circuit of the induction mechanism;

[0042] The upper cone 2 is detachably arranged on the lower cone 1. It is internally provided with a second installation groove 21, and its surface is provided with an outlet 22 communicating with the second installation groove 21;

[0043] The automatic wire rewinder 3 is located in the second installation groove 21 and includes a first wire 31 with one end connected to the power supply and the other end extending out from the outlet 22;

[0044] The projection assembly 4 includes a rotating body 42. One end of the rotating body 42 is rotatably fitted in the first installation groove 12, and the other end is provided with a projection module 41 capable of projecting a rectangular light band on the ground. One side is provided with a signal transmitter 43 and the other side is provided with a signal receiver 44;

[0045] As Figures 11-12 shown, the induction mechanisms are connected through the first wire 31 and the connection port 13 to form an integral structure and conduct power transmission;

[0046] The rectangular light bands projected by the projection modules 41 of several induction mechanisms on the ground form a fully enclosed or semi - enclosed warning area;

[0047] Adjacent induction mechanisms are connected through the first wire 31 and the connection port 13 arranged in the upper cone 2 to form an integral structure and conduct power transmission. Through the first wire 31, not only the effect of power transmission is achieved, but also all induction mechanisms are connected into a whole to improve their stability; the rectangular light bands projected by the projection modules 4 of several induction mechanisms on the ground form a fully enclosed or semi - enclosed warning area to improve the warning effect.

[0048] In this embodiment, at least one of the lower cones 1 of the induction mechanisms is provided with a battery; actually, as long as there is a battery in one induction mechanism, power supply can be realized without carrying too many batteries.

[0049] Preferably, after the upper cone 2 is installed on the lower cone 1, the circuit in the upper cone 2 is connected to the circuit in the lower cone 1.

[0050] Specifically, there are wires on the left and right sides inside the upper cone 2, and there are wires on the left and right sides inside the lower cone 1. After the upper cone 2 is installed on the lower cone 1, the circuit in the upper cone 2 is connected to the circuit in the lower cone 1. By adopting a split - type circuit design, once a part of the structure is damaged, it is not necessary to replace the whole; at the same time, before the upper cone 2 is installed on the lower cone 1, the induction mechanism as a whole is not powered on, which is safer.

[0051] As Figures 2-9As shown, a positioning groove 24 is provided on the lower surface of the upper cone 2, and a positioning protrusion 25 extending towards the lower surface of the upper cone 2 is provided on the bottom surface of the positioning groove 24. A guiding groove 26 is formed between the positioning groove 24 and the positioning protrusion 25. The top of the guiding groove 26 is recessed inward, and a conductive block is installed at the recessed part. The conductive block is connected to a wire inside the upper cone 2. A guiding groove 27 is also provided on the inner wall of the positioning groove 24; a positioning post 14 is provided on the upper surface of the lower cone 1. The diameter of the positioning post 14 is the same as that of the positioning groove 24. A positioning slot 15 cooperating with the positioning protrusion 25 is provided on the positioning post 14. A guiding protrusion 17 cooperating with the guiding groove 27 for limiting is provided on the outer surface of the positioning post 14. A conductive member 16 is provided at the edge of the positioning post 14. The conductive member 16 includes a column part 161 provided on the positioning post 14 and an elastic part 162 located on the side of the column part 161 and extending outward.

[0052] When installing the upper cone 2 onto the lower cone 1, the positioning post 14 is installed into the positioning groove 24, and the positioning protrusion 25 cooperates with the positioning slot 15 for positioning, and the guiding groove 27 cooperates with the guiding protrusion 17 for guiding. Since the diameter of the positioning post 14 is the same as that of the positioning groove 24, during installation, the elastic part 162 protrudes from the positioning groove 24, and the pressure from the inner side wall of the positioning groove 24 causes the entire conductive member 16 to bend slightly inward; continue to install the upper cone 2 downward, and the conductive member 16 enters the guiding groove 26 between the positioning groove 24 and the positioning protrusion 25, and the elastic part 162 undergoes a small deformation due to the extrusion between the inner side wall of the positioning groove 24 and the outer wall surface of the positioning protrusion 25; after the upper cone 2 is installed to the limit position, the guiding protrusion 17 abuts against the top of the guiding groove 27, the positioning protrusion 25 abuts against the bottom of the positioning slot 15, the conductive member 16 abuts against the top of the guiding groove 27, and the elastic part 162 returns to its original position due to elastic potential energy and enters the recess of the guiding groove 26 to contact the conductive block in the recess, realizing the connection of the circuit inside the upper cone 2 and the circuit inside the lower cone 1.

[0053] As Figures 3-4 shown, as a preferred method, a chamfer is provided at the bottom of the positioning slot 15, and a chamfer is provided at the end face of the positioning protrusion 25, which is convenient for positioning and guiding. At the same time, the extrusion distance of the guiding groove 26 to the conductive member 16 is reduced, which is convenient for the elastic part 162 to be installed into the recess of the guiding groove 26.

[0054] As a preferred method, an arc transition part 251 is provided at the connection between the chamfer at the end face of the positioning protrusion 25 and the outer wall surface, which is convenient for the conductive member 16 to enter the guiding groove 26 between the positioning groove 24 and the positioning protrusion 25.

[0055] As a preferred method, a third installation groove 23 is provided at the top of the upper cone, and a warning light 5 is installed in the third installation groove 23 to improve the warning effect.

[0056] As a preferred embodiment, the upper ends of the left and right side wires inside the upper cone 2 are disconnected, and conductive blocks are provided at the upper ends of the two wires. Conductive blocks are provided on both sides of the lower end of the warning light 5. After the warning light 5 is installed in the third installation groove 23, the upper ends of the left and right side wires inside the upper cone 2 are electrically connected. Then, the upper cone 2 is installed on the lower cone 1 to realize the electrical connection of the induction mechanism.

[0057] As Figure 11 shown, as a preferred embodiment, a plurality of guiding lights 6 are provided on the first wire 31, and a regular isolation warning pattern is formed on the overall structure formed by connecting with the induction mechanism; the isolation warning pattern is a plurality of obliquely arranged patterns, which cooperate with the rectangular warning area on the ground to improve the warning effect.

[0058] A tunnel accident warning and induction method includes the following steps:

[0059] S100: Place a number of induction mechanisms in the accident area in the tunnel and enclose a fully enclosed or semi-enclosed area; if the accident occurs in the middle of the lane, a full enclosure is required, and if the accident occurs on one side of the lane, only a semi-enclosure is needed;

[0060] S200: Connect the first wire 31 of the induction mechanism to the connection port 13 of the next induction mechanism to form an overall structure and conduct power transmission;

[0061] S300: The rectangular light bands projected by the projection modules 4 of a number of induction mechanisms on the ground form a fully enclosed or semi-enclosed warning area.

[0062] Preferably, a storage battery is installed on one of the induction mechanisms. It is only necessary to have a storage battery in one induction mechanism to achieve power supply, without the need to carry too many storage batteries.

[0063] Preferably, in S300, the signal emitted by the signal transmitter 43 of one induction mechanism is received by the signal receiver 44 of the adjacent induction mechanism. Because the vehicles in the tunnel will vibrate to a certain extent during driving, the projection component 4 on the induction mechanism may deflect due to vibration. The signal transmitter 43 and the signal receiver 44 are used in cooperation to detect whether the current projection component 4 is in place.

[0064] Preferably, in S300, once one or more of the projection components 4 deflect, the projection component 4 swings up and down until the signal emitted by the signal transmitter 43 of the induction mechanism is received by the signal receiver 44 of the adjacent induction mechanism or the signal receiver 44 of the induction mechanism receives the signal emitted by the signal transmitter 43 of the adjacent induction mechanism, and the projection component can be automatically adjusted according to the actual situation.

[0065] Specifically, a gyroscope can be installed on the projection component 4. Once it is detected that a certain projection component 4 deflects, the projection component 4 swings up and down reciprocally until the signal emitted by the signal transmitter 43 of the induction mechanism is received by the signal receiver 44 of the adjacent induction mechanism or the signal receiver 44 of the induction mechanism receives the signal emitted by the signal transmitter 43 of the adjacent induction mechanism.

[0066] Preferably, several induction mechanisms enclose a rectangle, and the projection module is arranged obliquely downward, and an outward-expanded rectangular warning area is formed on the ground projection. Through this outward-expanded rectangular warning area, the warning range of the induction mechanism can be expanded, further preventing the vehicle from colliding with the induction mechanism when driving in the tunnel and preventing secondary accidents.

[0067] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is subject to the scope defined by the claims. Several improvements and refinements made by those skilled in the art without departing from the spirit and scope of the present invention should also be regarded as the protection scope of the present invention.
