Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of road lighting testing equipment, specifically to an all-weather vehicle-mounted road lighting testing instrument. Background Technology
[0002] In urban roads, a large number of streetlights need to be deployed for nighttime illumination. The inspection and maintenance of traditional road lighting systems mainly rely on manual inspections, which are inefficient, costly, and lack comprehensive data. Therefore, the current method uses vehicle-mounted illuminance sensors for detection. However, illuminance sensors are not waterproof and can only be used in rainless conditions, which greatly limits their functionality. Moreover, the angle of the sensor needs to be manually aligned, making installation cumbersome. The tilt caused by bumps can also easily affect the accuracy of the detection. Utility Model Content

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] See Figures 1-6 As shown, the device includes a host 1 and two sensor units. The host 1 is equipped with multiple sensor interfaces 2 for connecting the sensor units. The host 1 is also equipped with a data interface 3 for connecting to a host device and a positioning module 4 for satellite positioning. The sensor interfaces 2 and data interfaces 3 are waterproof aviation interfaces. The sensor unit consists of an outer bracket 5, a two-dimensional adjuster and a sensor housing 10. The sensor housing 10 contains a sensor body 12. The sensor body adopts a planar built-in silicon photodiode illuminance sensor. Multiple magnets 18 are installed at the bottom of the outer bracket 5 for quick fixation. The two-dimensional adjuster is installed inside the outer bracket 5. The cylindrical sensor housing 10 is installed at the center of the two-dimensional adjuster. The top of the sensor housing 10 is sealed with a colorless optical glass encapsulation lens 11. The top of the sensor housing 10 is also equipped with a constant temperature device for heating the encapsulation lens 11 at a constant temperature.
[0025] The temperature control device includes a heat-conducting ring 13 embedded inside the opening of the sensor housing 10. The heat-conducting ring 13 has a heat-insulating wrapping 15 on its outer side and is tightly fitted to the side of the encapsulated lens 11 on its inner side. The heat-conducting ring 13 has a heating strip 14 embedded in it for uniform heating. The heat is uniformly conducted to the encapsulated glass through the heat-conducting ring 13 to prevent temperature differences from occurring in different parts. The opening of the sensor housing 10 is also equipped with multiple thermistors 16, the top surface of which is fitted to the bottom surface of the encapsulated lens 11 for real-time monitoring of the temperature of the encapsulated lens 11 to achieve constant temperature control.
[0026] The two-dimensional adjuster consists of a rotating ring 7 and an inner rotating frame 8. The two ends of the rotating ring 7 are rotatably mounted in the outer bracket 5 via two rotating shafts 6, and the two ends of the inner rotating frame 8 are rotatably mounted in the rotating ring 7 via two rotating shafts 9. The included angle between the two rotating shafts 6 and the two rotating shafts 9 is 90°, thereby realizing multi-angle adjustment. The sensor housing 10 is fixed at the center of the inner rotating frame 8. A counterweight 17 is provided at the center of the bottom of the inner rotating frame 8. The counterweight 17 is used to maintain balance. Holes for wire threading are provided at the bottom of the sensor housing 10 and the outer bracket 5, as well as inside the counterweight 17, to facilitate wiring. After wiring is completed, sealant is filled in for sealing. In addition, multiple drainage holes 19 are opened at the bottom of the inner rotating frame 8 to ensure that there is no water accumulation inside.
[0027] The outer bracket 5, rotating ring 7, rotating frame 8 and sensor housing 10 are all made of aluminum alloy to prevent magnetic attraction of magnet block 18. Aluminum alloy has good sealing performance, is lightweight and durable.
[0028] The usage process of this utility model:
[0029] When in use, the host 1 is installed on the vehicle being tested, and the sensor units are placed on the vehicle's hood. The sensor units will automatically attach to the hood under the action of the magnet 18. The two sensor units are 1m apart. The sensor units are connected to the host 1. Then, the personnel use a laptop computer as the host computer in the vehicle. The laptop is connected to the data interface 3 through a wire.
[0030] During installation and use, since the vehicle's hood cannot be horizontal and the angle will change when the vehicle runs over an object, the sensor housing 10 and the inner rotating frame 8 can rotate around the first rotating axis 6 and the second rotating axis 9 under the gravity of the counterweight 17, so that the internal sensor body 12 remains horizontal and upward without external adjustment.
[0031] When used in rainy weather, the encapsulated lens 11 keeps the sensor body in a sealed environment, and the encapsulated lens 11 has good light transmittance, so it can still perform detection work normally in rainy weather. When the weather temperature changes greatly, the heating strip 14 can be turned on, and the heat generated by the heating strip 14 is used to heat the encapsulated lens 11 evenly through the heat conduction ring 13, thereby preventing the surface from fogging. In snowy weather, it can be used to melt snow. The temperature of the encapsulated lens 11 can be monitored through the encapsulated lens 11, thereby turning the heating strip 14 on or off or adjusting its power to keep the temperature of the encapsulated lens 11 within the normal range, preventing the temperature from being too high or too low, and keeping its temperature stable. The heat insulation wrapping 15 isolates the heat, reducing the energy waste caused by heat conduction to the outside.
[0032] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
