Description

A pressure sensing road lighting device

technical field

The invention relates to the technical field of road lighting, in particular to a pressure-sensing road lighting device.

Background technique

With the rapid development of social traffic, road lighting devices play an increasingly important role. Road lighting improves the safety of driving at night, but it also consumes a lot of power resources. Today's highway night lighting is generally turned on at 7 o'clock in the night and turned off at 5 o'clock in the morning. The lighting time in some areas varies, but basically the street lighting time at night is more than 8 hours. During this period, there are not all vehicles passing by on the road. A large amount of power loss is caused. The street lights use the technology of unified opening and closing, and the lines are uniform and regular. The main gate determines the time of turning on the lights. Therefore, the lights are not switched on and off according to the actual situation, resulting in unnecessary loss of resources.

Beneficial effect

Due to the adoption of the above technical solution, the present invention has the following advantages and positive effects compared with the prior art: the road lighting device is designed to automatically turn on the light when the vehicle is approaching in the present invention, and automatically turn off the light after the vehicle leaves. device. It mainly uses the pressure sensor to detect whether there is a vehicle passing. When a vehicle passes, the pressure sensor will pass the feedback signal to the core processor to control the lighting of the road lighting device. After the vehicle leaves, after a period of delay, click Bright road lights go out. When passing through the next road lighting device, turn on the new road lighting device again, repeat the above steps, and realize intelligent lighting and extinguishing. The invention can reduce the electricity cost of the present highway on a large scale, and is beneficial to the further development of public transportation.

detailed description

Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

The embodiment of the present invention relates to a pressure-sensing road lighting device, as shown in Figure 1 and Figure 2, comprising a pressure sensor 1, a light pole 8, a processor 3, a light source 5 and a trigger switch 4, the light pole 8 Arranged along the edge of the road, the light source 5 and the trigger switch 4 are installed on the light pole 8; the trigger switch 4 is used to control the light source 5 to turn on or off, and the pressure sensor 1 is buried underground and located on the road surface of the road 2 directly below the center, and is connected to the input end of the processor 3 provided on the light pole 8 through the signal line 7; the output end of the processor 3 is connected to the trigger switch 4 through the signal line 7 for controlling the trigger switch 4 The opening and closing state of the pressure sensor 1 is used to detect whether there is a vehicle 6 passing on the highway, and sends a working signal to the processor 3 when a vehicle 6 passes, and the processor 3 controls the trigger switch 4 to make the light source 5 emit bright light. Wherein, the processor 3 can be an AT89C51 single-chip microcomputer, and the AT89C51 single-chip microcomputer can significantly improve the signal feedback speed and realize instant signal processing. The signal line may be a coaxial line, which can transmit various signals.

When the pressure sensor 1 detects that an object of 20kg-40t passes the road surface, it sends a working signal to the processor, so that it can smoothly detect whether there is a vehicle passing by. The position of the pressure sensor 1 is between 100 mm and 150 mm below the road surface 2 , and the horizontal length of the pressure sensor 1 is the same as the width of the road, thus ensuring that the vehicle will pass the pressure sensor 1 when driving in any direction.

The processor 3 controls the trigger switches 4 on the three light poles 8 closest to the pressure sensor 1 to close after receiving the working signal from the pressure sensor 1, so that the light sources on the three light poles 8 closest to the pressure sensor 1 5 to shine brightly. After the pressure sensor 1 feeds back the highway lighting device, the number of lights that are automatically turned on is 3, which are three light sources 5 at the front, middle and back centered on the vehicle 6, so as to ensure that the vehicle 6 is always in the illumination range. The light source 5 keeps emitting bright light within 60s after the vehicle 6 leaves the pressure sensor 1, and then automatically goes out. The distance between the light poles 8 is 15m-20m, so as to ensure that the vehicle can be within the normal illumination range during driving.

The working process of the present invention is as follows: when a vehicle 6 passes through the road surface 2 and the wheel presses over the pressure sensor 1, the pressure sensor 1 will be triggered to send a pressure signal, and the pressure sensor 1 will transmit the signal to the core processor 3, and the core processor 3 will pass through the pressure sensor 1. After the data is analyzed, a lighting signal is sent out to make the trigger switch 4 act, the trigger switch 4 is closed, and the light source 5 of the road lighting device is turned on. Since the information of the light sources 5 of every three road lighting devices is shared through the signal line 7, as long as the light source 5 of the middle light pole is triggered to light up, the light sources 5 of the front and rear light poles of the light pole will also light up. , so that the vehicle 6 is always running under the road conditions where the three light sources 5 are bright. After the vehicle 6 moves forward, the vehicle 6 at the position detected by the pressure sensor 1 is no longer there. Since the pressure signal cannot be collected, the light source 5 of the middle light pole is turned off after a delay of 60 seconds. The vehicle 6 will be detected again by the new pressure sensor 1 at the position of the next light source 5, trigger the new light source 5 to light up again, and begin to repeat the previous steps. Finally, every time the vehicle 6 passes above the pressure sensor 1, the front, middle and rear three light sources 5 will be turned on, while the other light sources 5 are not turned on, or are in the process of delaying turning off the lights. Realize the function of turning on and off the lights of intelligent roads.
