[0027] System Example

[0028] According to an embodiment of the present invention, a road lighting evaluation system considering meteorological factors is provided. Figure 1 Schematic diagram of a road lighting evaluation system considering meteorological factors according to an embodiment of the present invention. Figure 1 As shown, the road lighting evaluation system considering meteorological factors according to an embodiment of the present invention specifically includes:

[0029] Road illumination distribution measuring device, meteorological measuring device, electronic control device, positioning device and evaluation test platform;

[0030] like Figure 2 FIG. 1 is a schematic diagram of a road lighting evaluation system considering meteorological factors according to an embodiment of the present invention. Figure 2 The road lighting evaluation system considering meteorological factors shown includes:

[0031] The vehicle-mounted gantry is installed at the rear of the vehicle, two telescopic devices are installed on the vehicle-mounted gantry, the illuminance meter is installed on the telescopic devices, and the electric control box is installed on the rear bucket of the vehicle. A visibility meter and six meteorological elements instruments are installed on the roof.

[0032] The road illumination distribution measuring device comprises an illumination measuring array composed of a plurality of illumination meters, wherein the plurality of illumination meters are provided with different communication address codes, and the plurality of illumination meters are cascaded through waterproof cables, so as to obtain illumination distribution information of a preset road surface width; wherein at least one illumination meter is connected to the electronic control device through a waterproof cable; the road illumination distribution measuring device is fixed above the vehicle through a telescopic bracket, the telescopic bracket moves along one side to increase the width of the measured road surface, and the telescopic bracket is mounted on a gantry bracket made of an aluminum material.

[0033] The illuminance meter uses a waterproof aluminum shell, which is installed on the telescopic bracket by screws. The illuminance meters are cascaded through waterproof cables to achieve power supply and data transmission. Up to 16 illuminance meters can be cascaded. One of the illuminance meters is connected to the electronic control device through a waterproof cable. The electronic control device provides DC power to the illuminance meter and communicates with the electronic control device through communication methods such as 485 or 232 to upload measurement results. Each illuminance meter corresponds to a different communication address code for distinction.

[0034] Furthermore, the multiple illuminometers of the embodiment of the present invention are installed on two retractable cross bars, which can be extended to one side of the vehicle and cargo respectively during measurement to expand the width of the measured road surface. The retractable cross bars are installed on a gantry bracket made of aluminum profiles. The gantry bracket is installed in the pickup truck cargo and can be easily installed on the vehicle or removed from the vehicle.

[0035] The meteorological measuring device is used to measure meteorological parameters in real time and upload the meteorological parameters to the electronic control device;

[0036] The meteorological measuring device specifically includes: a meteorological visibility meter and a meteorological six-element detector; the meteorological visibility meter and the meteorological six-element detector are respectively arranged on both sides of the roof through a roof bracket;

[0037] The meteorological visibility meter is used to obtain visibility information based on the principle of light scattering; the meteorological visibility meter is installed on one side above the roof of the vehicle, with the measuring surface facing the road surface. Particles such as particulate matter and aerosols in the air encounter the light emitted by the light source on one side of the visibility meter and are scattered, and the forward scattered light is received by the receiver on the other side. The more particles in the air, the stronger the scattered light, the lower the meteorological visibility, and the worse the lighting effect. The meteorological visibility meter is connected to the electronic control device via a waterproof cable, which provides a DC power supply and uploads the measurement results to the electronic control device via 485 or 232 communication methods.

[0038] The six-element meteorological detector is used to obtain wind speed, wind direction, temperature, humidity, air pressure and rainfall type. The six-element meteorological detector is installed on the other side of the roof, and the wind speed and direction are measured using the ultrasonic Doppler principle. Since the vehicle is moving, the vehicle speed is measured by the Beidou navigation system installed in the electronic control box, and the wind speed and direction measurement results are corrected. Temperature, humidity and pressure are measured using electrode sensors. The rainfall type is measured by an optical sensor installed on the top of the six-element meteorological instrument, and the rainfall type is analyzed based on the different optical phenomena such as scattering, refraction and reflection generated by the water mist, raindrops and water flow on the top. The six-element meteorological detector is connected to the electronic control device through a waterproof cable, and the electronic control device provides a DC power supply, and uploads the measurement results to the electronic control device through 485 or 232 communication methods.

[0039] The positioning device is used to generate positioning information according to the positioning instruction of the evaluation test platform, and send the positioning information to the evaluation test platform;

[0040] The positioning device comprises:

[0041] A camera and a GPS positioning device are arranged on the roof of the vehicle, wherein the camera is used to identify the lamp pole data by taking photos and send the lamp pole data to the evaluation test platform;

[0042] The GPS positioning device is used to obtain GPS positioning information data and send the GPS positioning information data to the evaluation test platform.

[0043] The electronic control device is used to supply power to the road illumination distribution measuring device, the meteorological measuring device and the positioning device, and to send the illumination distribution information and meteorological parameters to the evaluation test platform;

[0044] The electronic control device has a built-in rechargeable DC voltage battery, and the rechargeable DC voltage battery outputs a variety of different voltages to power the road illumination distribution measurement device, the meteorological measurement device and the positioning device. The electronic control device receives the data sent by the road illumination distribution measurement device and the meteorological measurement device through the USB expansion port, and transmits the data sent by the road illumination distribution measurement device and the meteorological measurement device.

[0045] Furthermore, in a specific implementation of an embodiment of the present invention, the electric control device is installed in a vehicle-mounted gantry. A rechargeable 24V DC voltage battery is installed in the electric control device, and the battery outputs 5V, 12V or 24V after DC voltage regulation to power each measurement unit. The computer receives the measurement data transmitted by each sensor in 485 or 232 mode through the USB expansion port. The Beidou navigation device transmits the vehicle positioning information to the computer. The camera transmits the captured street light arrangement picture to the computer through the network interface.

[0046] The evaluation test platform is used to control the generation of positioning instructions through the acquired illumination distribution information, control the positioning device to obtain positioning information through the positioning instructions, and evaluate the road lighting status according to the positioning information, illumination distribution information and meteorological parameters.

[0047] The evaluation test platform is specifically used for:

[0048] Determine whether the illumination distribution information meets the preset illumination threshold. If so, generate a positioning instruction to control the camera to take pictures, and calculate the position information through the lamp pole data sent by the camera; if it does not meet the preset illumination threshold, use the GPS positioning information data as the position information; obtain the road lighting status according to the position information, illumination distribution information and meteorological parameters.

[0049] The evaluation test platform of the embodiment of the present invention is implemented by C language, such as Figure 4 FIG. 1 is a working principle diagram of a road lighting evaluation method considering meteorological factors according to an embodiment of the present invention; Figure 4 It can be seen that before the test starts, the illuminance meter, camera, and meteorological detector are powered by the electronic control device, and the test software in the laptop is opened. The software starts running and initializes the parameter configuration. The vehicle is started on the road. When the software receives the start test command, it enters the sampling judgment loop. First, the illuminance data is read. If the illuminance data is detected to meet the rising edge trend of the set threshold, the software will open the camera port and take a photo to identify the light pole data at the location. If no rising edge is detected, the GPS positioning data is directly sampled. Next, the meteorological visibility equipment data is sampled. The test data of a measurement point includes the illuminance data of the illuminance array, clock data, GPS location information data, visibility wind speed and direction and other meteorological data and light pole data (if any). If there is no stop command, the previous illuminance, light pole, GPS, and meteorological data sampling are cyclically performed. If the detection of a section of road surface is completed, the start stop command ends the test. The road lighting evaluation software analyzes the status of road lighting based on the data of a series of sampling points recorded and combined with meteorological conditions.

[0050] Figure 3 Schematic diagram of the connection of various devices of the road lighting evaluation system considering meteorological factors according to an embodiment of the present invention; Figure 3 It can be seen that the visibility meter, meteorological instrument, GPS / Beidou, and illuminance meter in the embodiment of the present invention are all connected to the electronic control device through 232 or 485 communication methods, and the camera uploads data to the electronic control device through a gigabit network port data transmission method.

[0051] By adopting the embodiments of the present invention, the following beneficial effects are achieved:

[0052] By installing meteorological visibility meters and meteorological six-element detectors on vehicles, meteorological factors are taken into consideration in the road lighting evaluation system, thereby improving the accuracy of the road lighting evaluation system to ensure safe lighting, facilitate travel, and achieve the goal of energy-saving and green lighting.
