Abstract
Description
Technical Field
[0001] The utility model relates to a traffic indication device for an underground tunnel intersection. Background Art
[0002] During the construction of a hydropower station, a large number of underground tunnels need to be excavated. Inevitably, there are intersections between the tunnels. During the peak period of the construction of an underground cavern group, there are certain safety risks when muck trucks, concrete mixer trucks, other vehicles and personnel enter and exit through the intersections. Currently, when various vehicles pass through the intersections, they mostly use the method of honking to inform the oncoming vehicles or staff. However, during the construction period, the environment in the tunnel is complex, the noise is loud and the lighting is dim. The method of honking will further increase the noise in the tunnel, and in the case of high noise, it will not be able to notify the oncoming vehicles or personnel in time, resulting in safety accidents. Content of the Utility Model
[0003] The purpose of the utility model is to provide a traffic indication device for an underground tunnel intersection, which is used to solve the problem that due to the complex environment, high noise and dim lighting in the tunnel during the construction period, the tunnel intersection cannot notify the oncoming vehicles or personnel in time, resulting in safety accidents.
[0004] In order to solve the above problems, the technical solution of the utility model is as follows:
[0005] A traffic indication device for an underground tunnel intersection includes an electrical cabinet, a measurement module installed in each tunnel, and traffic lights arranged at the tunnel intersection. The measurement module includes two laser rangefinders respectively arranged on the inner walls of the left and right sides of the tunnel. A controller is arranged in the electrical cabinet. The laser rangefinders are connected to the input end of the controller, and the traffic lights are connected to the output end of the controller.
[0006] The distance between the laser rangefinders on the left and right sides of the tunnel is 5 - 10 cm.
[0007] Grooves are formed on the inner wall of the tunnel, and the laser rangefinders are arranged in the grooves.
[0008] It further includes a wireless transmission module. The laser rangefinders are connected to a wireless receiving module connected to the input end of the controller through the wireless transmission module.
[0009] The traffic lights are suspended at the top of the tunnel intersection through a bracket.
[0010] The beneficial effects of the utility model are as follows: when a vehicle passes by, the signal of the indicator light changes, so that the vehicles and personnel in the tunnel can receive the information of oncoming vehicles in time, avoiding traffic accidents; at the same time, the device has a simple structure, low cost, is convenient and labor-saving, and can provide help for safe traffic during the construction of underground caverns. Description of the Drawings
[0011] The following further describes the utility model with reference to the drawings:
[0012] Figure 1 This is a three-dimensional structural schematic diagram of the present utility model.
[0013] Figure 2 This is a front view structural schematic diagram of the present utility model.
[0014] Figure 3 This is a schematic diagram of the connection relationship between the various electrical components of the present utility model.
[0015] In the figure: laser rangefinder 1, tunnel 2, electrical cabinet 3, traffic lights 4, controller 5, wireless receiving module 6, wireless transmitting module 7. Specific implementation mode
[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0017] A traffic indication device for an underground tunnel intersection includes an electrical cabinet 3, a measurement module installed in each tunnel, and traffic lights 4 arranged at the tunnel intersection. The measurement module includes two laser rangefinders 1 respectively arranged on the inner walls of the left and right sides of the tunnel. A controller 5 is provided in the electrical cabinet 3. The laser rangefinder 1 is connected to the input end of the controller 5, and the traffic lights 4 are connected to the output end of the controller 5. The distance d2 between the laser rangefinders 1 on the left and right sides of the tunnel is 5 - 10 cm, and the laser rangefinder 1 is 1 m away from the ground. The controller 5 is a PLC controller 5.
[0018] When the present utility model is in use: such as Figure 2As shown in the figure, when an object passes through the tunnel, it first passes through the front a laser rangefinder 1, records the distance change time M1 of the a rangefinder and the distance L1, then records the distance change time M2 of the rear b laser rangefinder 1, and also records the time and distance L2; the tunnel width is K, then (K - L1 - L2) can obtain the width of the passing object. When the width is less than 80 cm and greater than 10 cm, the object is judged as a person, otherwise the object is judged as a vehicle; M2 - M1 is the passing time of the object. Dividing it by the placement distance d2 of the laser rangefinder 1 can obtain the passing speed, and then dividing it by the intersection distance d1 of the laser rangefinder 1 can obtain the passing time S; when there are no vehicles and people on the oncoming side, the controller outputs 0, and the traffic light 4 shows a green light, indicating no people or vehicles; when there is a vehicle on the oncoming side, the controller outputs 1, and the traffic light 4 shows a red light, indicating there is a vehicle on the oncoming side, drive carefully; when there is a person on the oncoming side, the controller outputs 2, indicating there is a person on the oncoming side, and the traffic light 4 shows a yellow light, and the vehicle should slow down; the display time of the traffic light 4 is the passing time S of the object. After more than S + 2 seconds, if there is no further signal input, the traffic light 4 returns that no people and vehicles have passed. When the distance of the rear laser rangefinder 1 changes first, the controller does not perform further processing and still outputs 0. At this time, it is a vehicle passing on the oncoming side.
[0019] There are grooves on the inner wall of the tunnel, and the laser rangefinder 1 is arranged in the grooves. To prevent people or vehicles from hitting the laser rangefinder 1 when passing through the tunnel.
[0020] It also includes a wireless transmission module 7. The laser rangefinder 1 is connected to a wireless receiving module 6 connected to the input end of the controller 5 through the wireless transmission module. Reducing the amount of wiring and facilitating disassembly and assembly.
[0021] The traffic light 4 is suspended at the top of the tunnel intersection through a bracket. While playing a reminder role, it does not hinder the passage of vehicles or people.
[0022] The content described in the embodiments of this specification is only a list of the implementation forms of the utility model concept. The protection scope of the utility model should not be regarded as limited to the specific forms stated in the embodiments. The protection scope of the utility model also extends to equivalent technical means that those skilled in the art can think of according to the utility model concept.
