Description

Technical Field

[0001] The present invention relates to the technical field of urban road illumination detection, and in particular to an illumination detection system and method for urban roads. Background Art

[0002] Urban road lighting is an important part of urban infrastructure. Good nighttime lighting quality can ensure that vehicle drivers and pedestrians can clearly see obstacles on the road and other conditions around the road. On-site measurement of road lighting has certain particularities and needs to be carried out in outdoor environments at night. The measurement process and results are easily affected by many interference factors such as weather, advertising signs and vehicle headlights. Manual measurement on roads that have been opened to traffic also poses great safety risks.

[0003] Existing illumination detection often relies on an illuminance meter, also known as a lux meter. This type of equipment is now relatively mature, widely used and has a relatively simple structure. The equipment is generally composed of two structures: a microammeter and a photocell probe. The metal materials and semiconductor materials in the illuminance meter can produce a photoelectric effect under the influence of light. The potential difference caused by the photoelectric effect can reflect the illumination received by the battery. The accuracy of the illuminance meter detection is greatly affected by the outside world, and will be affected by the incident angle, ambient temperature, ambient humidity, and fatigue characteristics. In actual use, there will be large errors.

[0004] Photoresistors are semiconductor photosensitive electronic components with the characteristics of small size, high sensitivity, fast response speed, good consistency of spectral characteristics and gamma values, and good linearity. The resistance in a photoresistor changes according to the intensity of light. In practice, the relationship between the light received by a photoresistor and the resistance generated is not a linear relationship, such as Figure 1 As shown, when the light is weak, the resistance change of the photoresistor will be more obvious and sensitive.

[0005] Generally speaking, the illumination detection of urban roads only needs to determine whether the light intensity on the road is within a reasonable range, that is, whether the light is too low to meet the traffic needs; and whether the light is too high to cause energy waste;

[0006] The illumination detection system and method for urban roads of the present invention is to carry a detection device on a mobile vehicle and walk on the road to achieve measurement. The detection equipment can filter the light intensity of the road so that the road light acts on the photoresistor with a relatively weak brightness, which can greatly increase the accuracy and sensitivity of road lighting judgment and can also directly obtain the result of whether the light is in a reasonable range. Summary of the invention

[0007] The purpose of the present invention is to provide an illumination detection system and method for urban roads. The measurement is achieved by carrying a detection device on a mobile vehicle and walking on the road. The detection equipment can filter the light intensity of the road so that the road light acts on the photoresistor with a relatively weak brightness. This can greatly increase the accuracy and sensitivity of road lighting judgment, and can also directly obtain the result of whether the light is in a reasonable range.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an illumination detection system for urban roads, comprising a mobile mechanism and a controller, the mobile mechanism comprising a support plate, a filter box and a marking box are fixedly connected to the support plate, light-transmitting glass is embedded in the inner sides of both left and right ends of the filter box, a photoresistor is fixedly connected to the outer side of the light-transmitting glass on the right side, the photoresistor is arranged in a shield fixedly connected to the right end of the filter box, and a resistor meter for obtaining the resistance of the photoresistor is fixedly connected to the filter box;

[0009] When in use, the light on the road first enters through the translucent glass at the left end of the filter box, and then passes through the translucent glass inside the filter box and the translucent glass at the right end to shine on the photoresistor. The gas inside the filter box is in a closed state and does not exchange with the outside. The smoke particles can be suspended in the gas inside the filter box. By increasing the smoke particles in the gas inside the filter box, the light transmission effect of the filter box is changed, so that the photoresistor works in the sensitive range when the light is weak. When the resistance value of the photoresistor increases, the surface light intensity decreases; when the resistance value of the photoresistor decreases, the surface light intensity increases, which increases the sensitivity of the resistance change of the photoresistor, thereby increasing the sensitivity and accuracy of the detection.

[0010] Under the above settings, the present invention can realize measurement by carrying the detection equipment on a mobile vehicle and walking on the road. The detection equipment can filter the light intensity of the road so that the road light acts on the photoresistor with a relatively weak brightness, which can greatly increase the accuracy and sensitivity of road light judgment. When in use, the mobile mechanism is placed on the road to be detected, and the light source that meets the road standard illumination is placed on the light-transmitting glass at the left end for initialization. The light source on the road is sequentially irradiated on the photoresistor through the inside of the filter box and the light-transmitting glass at the right end. Under the action of the smoke particles inside the filter box, the light intensity obtained by the photoresistor will decrease, and the resistance change of the photoresistor is obtained by the resistor meter, so that the photoresistor works in the sensitive range when the light is weak, and high-sensitivity detection is achieved;

[0011] As a preferred embodiment of the illumination detection system for urban roads of the present invention, the top of the filter box is connected to a compensation cylinder, the inner side of the compensation cylinder is slidably connected to a first piston, the inner side of the compensation cylinder is provided with a spring, the two ends of the spring are respectively fixedly connected to the top of the first piston and the inner side of the top of the compensation cylinder, a downwardly protruding arc-shaped filter is fixedly connected to the inlet of the compensation cylinder, the center position of the filter is fixedly connected to a vibration motor, and the vibration motor is used to prevent smoke particles from adhering to the filter.

[0012] Under the above setting, the compensation cylinder is used to play a role of space compensation. When the gas with smoke particles inside the filter box increases, the gas will enter the compensation cylinder through the filter, and the smoke particles will remain in the filter box, so that the density of smoke particles in the filter box increases. When the second piston moves to the right, the gas in the filter box enters the left side of the control box through the through pipe, and a part of the gas with smoke particles follows and enters the control box, so that the gas space where the smoke particles are located is increased, the smoke particle content is diluted, and the smoke particle density is reduced. Reducing the light intensity by smoke is a conventional means in the prior art, which will not be elaborated here.

[0013] As a preferred illumination detection system for urban roads of the present invention, a support rod is fixedly connected to the inner side of the bottom end of the marking box, a rotating rod is rotatably connected to the top end of the support rod through a hinge, a control box is fixedly connected to the left end of the rotating rod, the inner side of the left end of the control box is connected to the inside of the filter box through a hose and a through pipe, an electric push rod is fixedly connected to the inside of the rotating rod, a second piston is fixedly connected to the movable end of the electric push rod, the left side of the control box and the second piston are also filled with the same gas with smoke particles as that in the filter box, and the density of smoke particles in the filter box is changed by sliding the second piston in the control box;

[0014] Under the above arrangement, because the rotating rod is supported and rotatably connected by the support rod, the left and right sides of the rotating rod constitute a lever mechanism, wherein the force arm of the control box on the left side of the support rod is smaller than the force arm on the right side of the support rod;

[0015] When the second piston moves to the left, the gas on the left side of the operating box enters the filter box through the through pipe, the gas passes through the filter and enters the compensation cylinder, and the smoke particles remain in the filter box, thereby increasing the density of the smoke particles in the filter box; when the second piston moves to the right, the gas in the filter box enters the left side of the operating box through the through pipe, and a part of the smoke particles follow and enter the operating box, thereby reducing the density of the smoke particles in the filter box.

[0016] As a preferred illumination detection system for urban roads of the present invention, the top of the marking box is rotatably connected with a rotating plate through a hinge, a marking assembly is arranged on the inner side of the right end of the marking box, and the marking assembly includes a fixed rod and a rotating shaft, the fixed rod is fixedly arranged at the bottom end of the marking box, the rotating shaft is rotatably connected in the support plate, the outer side of the fixed rod is fixedly connected with a spring, the outer side of the spring is detachably connected with a paper reel through a buckle, the top of the rotating shaft is connected with a paper receiving shaft through a key, the movable end of the reference paper on the paper reel is fixed to the paper receiving shaft, and when the paper receiving shaft rotates, the reference paper on the paper reel can be pulled;

[0017] When the second piston moves in the operating box, the rotating rod will tilt. A marking pen is arranged at the right end of the rotating rod, and the marking pen will draw a light intensity curve on the reference paper.

[0018] After the marking is completed, the rotating board can be opened to take out the drawn light intensity curve to provide a basis for adjusting the road lighting;

[0019] As a preferred embodiment of the illumination detection system for urban roads of the present invention, a top plate is fixedly connected to the inner side of the right end of the marking box, and the top plate supports the reference paper between the paper winding shaft and the paper receiving shaft to increase stability during the marking process.

[0020] As a preferred illumination detection system for urban roads of the present invention, a limit rod is fixedly connected to the inner side of the marking box, a slider is slidably connected to the outer side of the limit rod, the right end of the rotating rod is slidably connected to the inner rod, the sliding connection of the inner rod is used to compensate for the distance, the right end of the inner rod is rotatably connected to the left end of the slider, the right end of the slider is fixedly connected to the marking pen, and the marking pen can slide up and down with the limit rod as a track and leave a line on the reference paper.

[0021] As a preferred embodiment of the illumination detection system for urban roads of the present invention, a motor is fixedly connected to the inner side of the right end of the support plate, a reducer is fixedly connected to the end of the output shaft of the motor, the output end of the reducer is fixedly connected to the rotating shaft, and the rotation of the paper collection shaft is realized by the rotation of the motor.

[0022] As an illumination detection system for urban roads of the present invention, preferably, the moving mechanism also includes a support frame fixedly connected to the bottom end of the support plate, the bottom end of the support frame is fixedly connected to a connecting piece, the inner side of the connecting piece is rotatably connected to a moving wheel, the right side of the moving wheel rotating shaft is rotatably connected to a drive box, the input shaft of the drive box is a drive rod, the top end of the drive rod is fixedly connected to a second bevel gear, and the second bevel gear is meshed with the first bevel gear.

[0023] Under the above setting, when the motor rotates, the driving rod is driven to rotate by the motor, and the rotation of the driving rod is transmitted through the driving box and then drives the moving wheel to rotate, so that the mobile mechanism can walk on the road to achieve long-distance detection. Among them, driving the moving wheel to rotate after being transmitted by the driving box is a prior art. For example, meshing bevel gears can be respectively set on the moving wheel rotating shaft and the driving rod to realize transmission, which will not be elaborated here. In the process of motor rotation, the reducer and the rotating shaft rotate. The rotation of the rotating shaft can make the paper collection shaft rotate and pull the reference paper to walk on the top plate. The walking length of the reference paper is a fixed ratio with the walking distance of the mobile mechanism, that is, in the detection process of the mobile mechanism, the pull-out distance of the reference paper is a scaling of the detection path distance. Because the photoresistor works in the sensitive range, when the illumination on the road increases , the resistance of the photoresistor will drop rapidly. At this time, in order to maintain the original resistance, the controller will control the electric push rod to extend, so that the second piston moves to the left, and the density of smoke particles in the filter box increases. The leftward movement of the second piston will cause the operating box to tilt downward. At this time, the marking pen will slide upward on the reference paper. When the illumination on the road decreases, the resistance of the photoresistor will increase rapidly. At this time, in order to maintain the original resistance, the controller will control the electric push rod to contract, so that the second piston moves to the right, and the density of smoke particles in the filter box decreases. The rightward movement of the second piston will cause the operating box to tilt upward. At this time, the marking pen will slide downward on the reference paper. The reference paper can be understood as a small map on the walking path, so that the light curve on the road can be continuously drawn on the reference paper that walks at the same time as the road.

[0024] The illumination detection method for urban roads comprises the following steps:

[0025] S1: Place the mobile mechanism on the road to be inspected, and place a light source that meets the road standard illumination on the left end of the light-transmitting glass for initialization;

[0026] S2: The light source on the road passes through the inside of the filter box and the light-transmitting glass on the right end and shines on the photoresistor in turn. Under the action of the smoke particles inside the filter box, the light intensity obtained by the photoresistor will decrease. The resistance change of the photoresistor is obtained through the resistor meter, so that the photoresistor works in the sensitive range when the light is weak, and high-sensitivity detection is achieved. In the initial state, the light source that meets the road standard illumination can fall into the middle position of the sensitive range of the photoresistor after entering the light-transmitting glass on the left end, and the rotating rod is in a balanced state;

[0027] S3: The motor rotates, and the motor drives the driving rod and the moving wheel to rotate, so that the mobile mechanism can walk on the road to achieve long-distance detection. During the rotation of the motor, the reducer and the shaft rotate. The rotation of the shaft can rotate the paper collection shaft and pull the reference paper to walk on the top plate. The walking length of the reference paper is a fixed ratio to the walking distance of the mobile mechanism, that is, during the detection process of the mobile mechanism, the pulling distance of the reference paper is a scaled ratio of the detection path distance.

[0028] S4: Because the photoresistor works in a sensitive range, when the illumination on the road increases, the resistance of the photoresistor will drop rapidly. At this time, in order to maintain the original resistance, the controller will control the electric push rod to extend, so that the second piston moves to the left, and the density of smoke particles in the filter box increases. The leftward movement of the second piston will cause the control box to tilt downward. At this time, the marking pen will slide upward on the reference paper. When the illumination on the road decreases, the resistance of the photoresistor will increase rapidly. At this time, in order to maintain the original resistance, the controller will control the electric push rod to contract, so that the second piston moves to the right, and the density of smoke particles in the filter box decreases. The rightward movement of the second piston will cause the control box to tilt upward. At this time, the marking pen will slide downward on the reference paper, thereby continuously drawing a light curve on the road on the reference paper that runs at the same speed as the road.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The illumination detection system for urban roads of the present invention can realize measurement by carrying the detection equipment on a mobile vehicle and walking on the road. The detection equipment can filter the light intensity of the road so that the road light acts on the photoresistor with a relatively weak brightness, which can greatly increase the accuracy and sensitivity of road light judgment. When in use, the mobile mechanism is placed on the road to be detected. The light source on the road is sequentially irradiated on the photoresistor through the light-transmitting glass inside and on the right end of the filter box. Under the action of smoke particles inside the filter box, the light intensity obtained by the photoresistor will decrease. The resistance change of the photoresistor is obtained by a resistor meter, so that the photoresistor works in a sensitive range when the light is weak. When the resistance of the photoresistor increases, the surface light intensity decreases. When the resistance of the photoresistor decreases, the surface light intensity increases, and the resistance change sensitivity of the photoresistor is increased, thereby increasing the sensitivity and accuracy of the detection and realizing high-sensitivity detection.

[0031] 2. The illumination detection system for urban roads is provided with a compensation cylinder for space compensation. When the gas with smoke particles inside the filter box increases, the gas will pass through the filter into the compensation cylinder, while the smoke particles remain in the filter box, increasing the density of the smoke particles in the filter box. When the second piston moves to the right, the gas in the filter box enters the left side of the control box through the through pipe, and a part of the gas with smoke particles follows and enters the control box, increasing the gas space where the smoke particles are located, diluting the smoke particle content, and reducing the density of the smoke particles.

[0032] 3. The illumination detection system for urban roads is supported by the support rod and rotatably connected, so that the left and right sides of the rotating rod constitute a lever mechanism, wherein the force arm of the control box on the left side of the support rod is smaller than the force arm on the right side of the support rod. When the second piston moves in the control box, the rotating rod will tilt. A marking pen is provided at the right end of the rotating rod, and the marking pen will draw a light intensity curve on the reference paper.

[0033] 4. The illumination detection system for urban roads, the motor rotates, and the motor drives the driving rod and the moving wheel to rotate, so that the mobile mechanism can walk on the road to achieve long-distance detection. During the rotation of the motor, the reducer and the shaft rotate. The rotation of the shaft can rotate the paper collection shaft and pull the reference paper to walk on the top plate. The walking length of the reference paper is a fixed ratio to the walking distance of the mobile mechanism, that is, during the detection process of the mobile mechanism, the pulling distance of the reference paper is a scaling of the detection path distance. Because the photoresistor works in the sensitive range, when the illumination on the road increases, the resistance value of the photoresistor will drop rapidly. At this time, in order to maintain the original resistance value , the controller will control the electric push rod to extend, so that the second piston moves to the left, and the density of smoke particles in the filter box increases. The leftward movement of the second piston will cause the operating box to tilt downward. At this time, the marking pen will slide upward on the reference paper. When the illumination on the road decreases, the resistance of the photoresistor will increase rapidly. At this time, in order to maintain the original resistance, the controller will control the electric push rod to contract, so that the second piston moves to the right, and the density of smoke particles in the filter box decreases. The rightward movement of the second piston will cause the operating box to tilt upward. At this time, the marking pen will slide downward on the reference paper, thereby continuously drawing a light curve on the road on the reference paper that is running at the same level as the road.

[0047] When in use, the light on the road first enters through the light-transmitting glass 12 at the left end of the filter box 8, and then passes through the light-transmitting glass 12 inside and at the right end of the filter box 8 to illuminate the photoresistor 13. The gas inside the filter box 8 is in a closed state and is not exchanged with the outside. The smoke particles can be suspended in the gas inside the filter box 8. By increasing the smoke particles in the gas inside the filter box 8, the light transmission effect of the filter box 8 is changed, so that the photoresistor 13 works in a sensitive range when the light is weak. When the resistance value of the photoresistor 13 increases, the surface light intensity decreases. When the resistance value of the photoresistor 13 decreases, the surface light intensity increases, and the resistance change sensitivity of the photoresistor 13 is increased, thereby increasing the sensitivity and accuracy of the detection.

[0048] Under the above settings, the present invention can realize measurement by carrying the detection equipment on the road on a mobile carrier. The detection equipment can filter the light intensity of the road so that the road light acts on the photoresistor with a relatively weak brightness, which can greatly increase the accuracy and sensitivity of road light judgment. When in use, the mobile mechanism is placed on the road to be detected, and the light source on the road is sequentially irradiated on the photoresistor 13 through the inside of the filter box 8 and the light-transmitting glass 12 on the right end.

[0061] In the initial state, the rotating rod 15 is in a balanced state, and the motor 7 rotates, and the driving rod 5 and the moving wheel 2 are driven by the motor 7 to rotate, so that the mobile mechanism can walk on the road to achieve long-distance detection. During the rotation of the motor 7, the reducer 22 and the rotating shaft 35 rotate. The rotation of the rotating shaft 35 can rotate the paper collection shaft 34 and pull the reference paper 30 to walk on the top plate 32. The walking length of the reference paper 30 is a fixed ratio to the walking distance of the mobile mechanism, that is, during the detection process of the mobile mechanism, the pulling distance of the reference paper 30 is a scaling of the detection path distance. Because the photoresistor 13 works in the sensitive range, when the illumination on the road increases, the resistance value of the photoresistor 13 will drop rapidly. At this time, in order to maintain the original resistance value, the controller 42 will control the electric push rod 16 to extend, so that the second piston 39 moves to the left, and the density of smoke particles in the filter box 8 increases. The leftward movement of the second piston 39 will cause the control box 31 to tilt downward. At this time, the marking pen 40 will slide upward on the reference paper 30. When the illumination on the road decreases, the resistance value of the photoresistor 13 will increase rapidly. At this time, in order to maintain the original resistance value, the controller 42 will control the electric push rod 16 to contract, so that the second piston 39 moves to the right, and the density of smoke particles in the filter box 8 decreases. The rightward movement of the second piston 39 will cause the control box 31 to tilt upward. At this time, the marking pen 40 will slide downward on the reference paper 30, thereby continuously drawing a light curve diagram on the road on the reference paper 30 that runs at the same speed as the road;

[0062] The present invention also discloses an illumination detection method for urban roads, the steps of which are:

[0063] S1: Place the mobile mechanism on the road to be inspected, and place a light source that meets the road standard illumination on the left end of the light-transmitting glass 12 for initialization;

[0064] S2: The light source on the road sequentially passes through the inside of the filter box 8 and the light-transmitting glass 12 at the right end to illuminate the photoresistor 13. Under the action of the smoke particles inside the filter box 8, the light intensity obtained by the photoresistor 13 will decrease. The resistance change of the photoresistor 13 is obtained by the resistor 14, so that the photoresistor 13 works in the sensitive range when the light is weak, and high-sensitivity detection is achieved. In the initial state, the light source that meets the road standard illumination can fall into the middle position of the sensitive range of the photoresistor 13 after entering the light-transmitting glass 12 at the left end, and the rotating rod 15 is in a balanced state;

[0065] S3: The motor 7 rotates, and the motor 7 drives the driving rod 5 and the moving wheel 2 to rotate, so that the mobile mechanism can walk on the road to achieve long-distance detection. During the rotation of the motor 7, the reducer 22 and the rotating shaft 35 rotate. The rotation of the rotating shaft 35 can rotate the paper collection shaft 34 and pull the reference paper 30 to walk on the top plate 32. The walking length of the reference paper 30 is a fixed ratio to the walking distance of the mobile mechanism, that is, during the detection process of the mobile mechanism, the pulling distance of the reference paper 30 is a scaled ratio of the detection path distance;

[0066] S4: Because the photoresistor 13 works in the sensitive range, when the illumination on the road increases, the resistance of the photoresistor 13 will drop rapidly. At this time, in order to maintain the original resistance, the controller 42 will control the electric push rod 16 to extend, so that the second piston 39 moves to the left, and the density of smoke particles in the filter box 8 increases. The leftward movement of the second piston 39 will cause the control box 31 to tilt downward. At this time, the marking pen 40 will slide upward on the reference paper 30. When the illumination on the road decreases, the resistance of the photoresistor 13 will increase rapidly. At this time, in order to maintain the original resistance, the controller 42 will control the electric push rod 16 to contract, so that the second piston 39 moves to the right, and the density of smoke particles in the filter box 8 decreases. The rightward movement of the second piston 39 will cause the control box 31 to tilt upward. At this time, the marking pen 40 will slide downward on the reference paper 30, thereby continuously drawing a light curve on the road on the reference paper 30 that travels at the same speed as the road.
