Abstract
Description
Technical Field
[0001] The utility model relates to the field of traffic warning devices, and more particularly to a highway safety device. Background Art
[0002] In highway traffic systems, at large-angle turns (such as right-angle corners), due to factors such as road layout, building obstruction, or the height of the vehicle itself, the road on the other side of the turn becomes a blind section for the driver. The driver cannot see the road conditions on the other side and faces a serious blind spot problem. Especially when a vehicle overtakes at a turn, if there is a car in the blind section on the opposite side, a traffic accident is very likely to occur.
[0003] Currently, the only safety measure at highway bends is to install reflective convex mirrors. Reflective convex mirrors can simultaneously illuminate the roads on both sides of the bend, and the driver can use the reflective convex mirrors to observe whether there are cars on the blind section. However, in poor lighting conditions, such as at night, in rainy days, or in foggy days, the field of vision of the reflective convex mirrors may be greatly reduced or even completely ineffective, resulting in the driver's field of vision still being limited. Therefore, it is necessary to design a new type of safety device suitable for highway bends. Utility Model Content
[0004] To achieve the above objectives, the present invention provides the following technical solutions:
[0005] A highway safety device includes a warning light disposed at a highway corner and pressure sensors disposed on blind sections on either side of the highway corner. The pressure sensors are connected to the warning light and activate an alarm when the warning light simultaneously receives sensing signals from the pressure sensors on both sides. A timer is disposed between the pressure sensor and the warning light and maintains the sensing signal from the pressure sensor for X seconds.
[0006] The utility model is further configured as follows: the pressure sensor is extended along the width direction of the blind road section.
[0007] The utility model is further configured to include a speed bump, wherein the speed bump is extended along the width direction of the blind road section, and the pressure sensor is arranged inside the speed bump.
[0008] The utility model is further configured as follows: a controller is provided in the warning light, the pressure sensor is connected to the controller via a timer, and when the controller receives sensing signals from the pressure sensors on both sides at the same time, the warning light is controlled to turn on.
[0009] The utility model is further configured as follows: the timer is a 555 timer in a monostable mode.
[0010] The utility model is further configured as follows: the timer maintains the sensing signal of the pressure sensor for 5-10 seconds.
[0011] The utility model is further configured as follows: the pressure sensor is arranged on a blind road section 20-40 meters away from the warning light.
[0012] The present invention is further configured to include a power supply module, which supplies power to the entire device.
[0013] Compared with the prior art, the present invention has at least the following advantages:
[0014] 1. Install pressure sensors on both sides of the blind road. When there are vehicles passing on both sides, the pressure sensors on both sides output sensing signals to form a path for the warning light circuit, so that the warning light turns on. By setting a timer, the sensing signal of the pressure sensor can last for a period of time. As long as the other pressure sensor is also pressurized during this period, the warning light can be turned on to remind the driver that there is a vehicle on the opposite side and that he needs to slow down and not overtake, thereby improving driving safety at highway corners.
[0015] 2. The warning light will light up only when receiving induction signals from both sides, avoiding the situation where the warning light will light up when there is a car on only one side, causing a waste of electricity. When the induction signal time maintained by the timer ends, the warning light circuit cannot form a path and the warning light automatically turns off, saving electricity.
[0016] 3. The pressure sensor is installed in the speed bump, which can also make the driver slow down and further improve the safety of the road bends. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.
[0024] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0025] A highway safety device, such as Figure 1 and Figure 2 As shown, it includes a warning light 2 set at a highway corner, and also includes pressure sensors 3 respectively set on the blind sections 1 on both sides of the highway corner. The pressure sensors 3 are connected to the warning light 2. When the warning light 2 receives sensing signals from the pressure sensors 3 on both sides at the same time, the warning light 2 lights up. If the sensing signal from only one side of the pressure sensor 3 is received, the warning light 2 will not light up. A timer is set between the pressure sensor 3 and the warning light 2. The timer maintains the sensing signal of the pressure sensor 3 for X seconds. As long as the warning light 2 receives the sensing signal from either side within X seconds, and then receives the sensing signal from the other side, the warning light 2 lights up.
[0026] A controller is provided in the warning light 2. The pressure sensor 3 is connected to the controller through a timer. The sensing signals of the pressure sensors on both sides are connected to the two input ends of the controller respectively. The output end of the controller controls the switch of the warning light 2. The controller has an AND gate circuit. When the controller receives the sensing signals from the pressure sensors 3 on both sides at the same time, that is, when the two signals are at a high level at the same time, the controller outputs a high level to control the warning light 2 to turn on.
[0027] A timer is connected between the pressure sensor 3 and the controller. In this embodiment, the timer specifically adopts a 555 timer in monostable mode. When the pressure sensor 3 outputs a sensing signal, the timer will maintain the output high level for X seconds. The timer can maintain the sensing signal time of the pressure sensor 3 within 5-10 seconds. In this embodiment, it is specifically set to 5 seconds. When the pressure sensor 3 on one side is run over by a vehicle, the pressure sensor 3 on the other side is also run over by the vehicle within 5 seconds, and the warning light 2 will be turned on, avoiding the situation where the warning light 2 cannot be triggered due to the vehicles on both sides running over it one after another.
[0028] When the signal delay on one side ends, it is impossible for both pins to be high at the same time. The controller does not output a high level and the warning light 2 circuit is not connected. Therefore, the warning light 2 will automatically turn off without wasting electricity.
[0029] The calculation formula for delay is: t=1.1RC (t is time, R is resistance, and C is capacitance). The resistor can be a variable resistor, and the extension time can be adjusted according to specific road conditions.
[0030] like Figure 2 and Figure 3 As shown, the pressure sensor 3 is extended along the width direction of the road to ensure that the pressure sensor 3 can be pressed when the vehicle passes by the road. The highway safety device also includes a speed bump 4, which is extended along the width direction of the road. The pressure sensor 3 is arranged in the speed bump 4. The length of the speed bump 4 is greater than the length of the pressure sensor 3. When the vehicle passes over the speed bump 4, the pressure sensor 3 will be triggered. The setting of the speed bump 4 protects the pressure sensor 3. The pressure sensor 3 will not be exposed to the outside, making it not easily damaged. It can also make the driver slow down and drive slowly, further improving the safety of driving at turns.
[0031] The pressure sensor 3 is set on the blind section 1 between the warning light 2 (20 meters-40 meters). It can be set according to the actual situation of the section and the average vehicle speed. In a section with a faster speed, the pressure sensor 3 can be set farther away from the warning light 2 to give the driver sufficient reaction time. In this embodiment, it is specifically set at the distance from the warning light 2 (30 meters). For example, when the left pressure sensor 3 is pressed for 4 seconds, the controller outputs a high level for 1 second when the right pressure sensor 3 is just pressed.
[0032] like Figure 4 As shown, this embodiment increases the duration of the warning light by adding a timer between the controller and the warning light. The timer and the controller are connected via a NOT gate, which converts the high level output from the controller's C port into a low level to drive the timer to work normally (the voltage at pin 2 of the 555 timer must be less than 1 / 3 VCC to work normally).
[0033] The warning light is connected to a relay, which is connected to a timer. The timer outputs a signal to control whether the relay coil is energized, thereby controlling the armature of the relay to be attracted (S in 4 in the figure), so that the static contact and the moving contact are electrically connected, that is, the conduction between the light and the power supply is achieved, thereby improving its safety performance.
[0034] The warning light 2 includes a mounting column at the bottom and a lamp body at the top. The lamp body is cylindrical, and when the warning light 2 is on, two colors of light flash alternately, so that the warning light 2 can be clearly seen on both sides of the turn.
[0035] The highway safety device further includes a power module, which supplies power to the entire device, including the pressure sensor 3 , the warning light 2 and the internal circuit module.
[0036] The working process of this utility model is as follows:
[0037] When a vehicle on one side presses on the pressure sensor 3, the pressure sensor 3 outputs a sensing signal, and the timer maintains the signal for 5 seconds. If a vehicle on the other side of the blind section 1 also presses on the pressure sensor 3 within 5 seconds, the controller turns on the warning light 2 to remind the driver that there is a vehicle on the opposite side of the turn. After the timer maintains the signal time, the warning light 2 automatically turns off.
[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
