Description

Technical Field

[0001] The present invention relates to the field of measurement technology, in particular to a tower tilt early warning device based on satellite and unmanned aerial vehicle photography and a usage method thereof. Background Art

[0002] Poles and towers (including electric poles and electric towers, so the quantifier of poles and towers in the present invention is "individual"), especially poles and towers located on high-voltage lines, are prone to tilting and even toppling due to various natural and man-made influences, which will bring safety hazards.

[0003] Although there are certain requirements for the verticality of the tower when it is buried, it is impossible to know in time whether its tilt angle exceeds the safety range during subsequent use, and it is impossible to make timely adjustments. Summary of the Invention

[0004] The main problem solved by the present invention is how to send out an early warning signal in time after a pole tower tilts.

[0005] The tower tilt warning device based on satellite and drone photography is characterized by comprising a green laser module, a diffuse reflector, a red phosphor, a lampshade, and a fixed end. The green laser module is fixed in the lampshade, and the green laser it emits points vertically upward. When the device is placed vertically, the diffuse reflector is located directly above the green laser.

[0006] The cross section of the red phosphor is a ring, and the diffuse reflector is located directly above the empty portion in the middle of the ring. The diffuse reflector is made of a mixture of a transparent material and a reflective substance, wherein the transparent material includes glass and plastic, and the reflective substance includes metal. The lower surface of the diffuse reflector is higher than the upper surface of the red phosphor. The diffuse reflector and the red phosphor are fixed as a whole, and the diffuse reflector and the red phosphor are suspended in the lampshade by a rope, and the lampshade is fixed to the pole tower through the fixed end.

[0007] When the tower is in a vertical state, the green laser shines on the diffuse reflector to emit diffuse green light; when the tower is in a tilted state, the green laser shines on the red phosphor to emit diffuse red light as a warning; the upper surface of the lampshade is transparent, which facilitates the diffuse green light and diffuse red light to be emitted upwards.

[0008] The laser module is closed during the day and turned on at night to facilitate aerial photography by satellites and drones. It also serves as a marker for the tower to prevent pedestrians and vehicles from accidentally colliding with it.

[0009] The specific working principle of the device is as follows: when the tower is in a vertical state, the device is placed vertically, the diffuse reflector is located in the direction of the green laser, and the green laser shines on the diffuse reflector to emit green light; when the tower is in a tilted state, the device tilts, and the direction of the green laser also tilts, the position of the red phosphor changes to the direction of the green laser, and the green laser shines on the red phosphor to emit red light as a warning. The red phosphor is made of phosphor powder, which is a mature existing technology and is easy to prepare.

[0010] The beneficial effects are as follows:

[0011] When the tower is in a vertical state, the device emits green light; when the tower is in a tilted state, the device emits red light as a warning. The emitted light is diffuse reflection, which can prevent the laser from shooting directly upward and affecting the pilot. At the same time, the overall direction of light emission is toward the sky. The difference between green and red is obvious, which is convenient for satellite and drone photography and identification.

[0012] When the tower is in a vertical state, the diffuse reflector emits green light diffusely reflected in all directions. The lower surface of the diffuse reflector is higher than the upper surface of the red phosphor. That is, there is a certain distance between the diffuse reflector and the red phosphor, which can reduce the red light generated by the green light entering the red phosphor. This ensures that the tower basically does not emit red light when it is vertical, and only emits obvious red light when it is tilted. The warning signal is obvious.

[0013] When the diffuse reflector emits green light, it can indicate that the tower is in a vertical state and can also serve as a sign of the tower at night to prevent pedestrians and vehicles from accidentally hitting the tower, achieving multiple goals at one stroke.

[0014] The laser module is turned off during the day and turned on at night. Firstly, it can save electricity. At the same time, the tilt warning signal is more obvious at night, and satellite and drone photography is clearer. Secondly, since the tilt of the tower is usually a slow process that accumulates day by day, only issuing the tilt warning signal at night is sufficient to monitor the tilt change process and issue the warning signal in time.

[0015] The vertical cross section of the diffuse reflector is in the shape of a convex character as a whole, and the four corners above the middle of the convex character are all rounded.

[0016] The beneficial effect is that the vertical cross-section of the diffuse reflector is in the shape of a convex character as a whole, which has the following effects: first, the convex character has a certain height difference between the upper and lower parts, that is, the diffuse reflector is not a plane, and the light it emits is more three-dimensional, and its luminous angle can exceed 180 degrees, which is more like a light bulb, which can be easily observed from all directions, and can better identify the tower; secondly, the intensity of the laser emitted by the current laser module is Gaussian distributed from the edge to the center. At the same time, the top of the convex character is convex upward, that is, the thickness of the diffuse reflector corresponding to the middle in the laser direction is greater than that of the edge, and is also Gaussian distributed. The diffuse reflector in the middle part can further diverge the laser, and the light is more divergent to the left and right sides of the diffuse reflector, thereby weakening the luminous intensity in the middle, avoiding the excessive intensity of the light emitted directly upward to affect the pilot, making the green light emitted on the diffuse reflector very uniform, extending the service life of the diffuse reflector, and better identifying the tower. In the prior art, planar fluorescent sheets are commonly used. The fluorescent sheets are made by applying fluorescent powder to a glass sheet. Their luminous angle cannot exceed 180 degrees. They are usually used for small-angle lighting such as flashlights and car lights, and do not have the three-dimensional large-angle luminous effect of the present invention.

[0017] The inner diameter of the circular ring is larger than the diameter of the green laser spot; and the transverse width of the diffuse reflector is equal to the inner diameter of the circular ring.

[0018] The beneficial effect is that when the inner diameter of the ring is larger than the diameter of the green laser spot, the green laser will not irradiate the red phosphor within a certain tilt angle of the tower, so a certain tilt angle is allowed, which is in line with the actual situation (if the inner diameter of the ring is equal to the diameter of the green laser spot, then as long as there is a slight tilt, the green laser will irradiate the red phosphor and emit red light, which is too strict and does not conform to the actual situation); the lateral width of the diffuse reflector is equal to the inner diameter of the ring, that is, there is no lateral gap between the diffuse reflector and the red phosphor, and the green laser will at least enter one of the above-mentioned two, avoiding the laser being directly emitted upwards and affecting the pilot. At the same time, the laser can be fully used to identify the tower (of course, the green laser may also be divided into two parts and simultaneously enter the diffuse reflector and the red phosphor, but in any case, as long as it enters the red phosphor and produces red light, a tilt warning signal is issued).

[0019] The red phosphor is formed by mixing a transparent material and red phosphor powder, and the transparent material includes transparent glass and transparent plastic.

[0020] The beneficial effect is that the red phosphor is not a fluorescent sheet. It has a certain thickness, allowing green light to fully contact the red phosphor, producing sufficient red light. At the same time, it has more uniform diffuse reflection in all directions, and the light it emits is more three-dimensional. The light emission angle can exceed 180 degrees, more like a light bulb, which can be easily observed from all directions and better identify the tower. In the existing technology, flat fluorescent sheets are generally used. The light emission angle cannot exceed 180 degrees and does not have the three-dimensional wide-angle light effect of the present invention.

[0021] There are at least three ropes, the ropes are of equal length, the ropes are evenly distributed around the perpendicular bisector of the ring, and the distance between the top ends of the ropes is greater than the distance between the bottom ends thereof.

[0022] Advantageously, the ropes are evenly distributed around the perpendicular midline of the ring, and the distance between the rope tops is greater than the distance between their bottoms. This rope connection ensures the vertical suspension stability of the diffuse reflector and red phosphor when the device is placed vertically. Furthermore, when the device is tilted, the diffuse reflector deviates from the direction of the green laser, causing the green laser to strike the red phosphor and emit red light. Most importantly, the top ends of the rope connections are dispersed and offset from directly above the green laser, thus preventing light from being blocked. Preferably, there are at least eight ropes, as more ropes provide a more accurate reflection of the device's tilt angle (of course, some ropes may bend due to lack of force) and provide a more stable suspension for the diffuse reflector and red phosphor. Furthermore, the rope length is limited, allowing the diffuse reflector and red phosphor to move only within a certain range during tilt. If the range of movement is too large, the diffuse reflector and red phosphor will exceed the range of the laser's illumination, resulting in a failure to emit red light. In other words, when the tilt angle is too large, red light will not be emitted, making an effective warning impossible. Limiting the rope length can avoid this problem.

[0023] It also includes a battery module and a solar module. The battery module supplies power to the laser module, and the solar module charges the battery module.

[0024] The beneficial effect is that the solar module solves the power supply problem of the green laser module. At the same time, compared with ordinary light sources such as LED, laser lighting has high luminous efficiency, consumes less energy at the same brightness, and can extend the time of the identification tower at night.

[0025] Usage of the device:

[0026] During installation, ensure that the tower is in a vertical state and the device is fixed vertically on the tower;

[0027] At night, using a satellite or drone to photograph the area where the tower is located, obtaining photos of the light-emitting points of the device on the tower in the area, wherein the light-emitting points have geographic coordinates;

[0028] The luminous point is analyzed correspondingly with the pre-stored geographical coordinates of the tower. If the geographical coordinates of the tower are green, it means that the tower is in a vertical state; if the geographical coordinates of the tower are red, it means that the tower is in a tilted state; if the color displayed at the geographical coordinates of the tower is the same as the surrounding area, it means that the device of the tower is blocked or damaged and needs to be adjusted.

[0029] The method has the following beneficial effects: The device has the beneficial effects of the method. Most importantly, the green and red lights emitted by the device are generally directed upward, and the green and red lights are clearly distinguishable, facilitating satellite and drone photography. Furthermore, the towers are spaced at least several dozen meters apart, providing sufficient spacing for satellite imaging and distinction. Furthermore, computers can automatically identify the light points, allowing satellites to monitor a large area at a time. The color displayed at the tower's geographic coordinates is the same as the surrounding area; that is, the light point corresponding to the tower's geographic coordinates cannot be found in the photograph.

[0030] The tower tilt warning device based on satellite and drone photography is characterized by comprising a green laser module, a diffuse reflector, a red phosphor, a lampshade, and a fixed end. The green laser module is fixed in the lampshade, and the green laser it emits points vertically upward. When the device is placed vertically, the diffuse reflector is located directly above the green laser.

[0031] The cross section of the red phosphor is a ring, the diffuse reflector is located directly above the empty portion in the middle of the ring, the diffuse reflector is made of a mixture of a transparent material and a reflective substance, the transparent material includes glass and plastic, and the reflective substance includes metal. The lower surface of the diffuse reflector is located higher than the upper surface of the red phosphor. The diffuse reflector and the red phosphor are fixed as a whole, and the lampshade is fixed to the pole tower through the fixed end.

[0032] The diffuse reflector is a sphere, which is fixedly connected to the red fluorescent body through a hanging rod. The sphere is connected to the lampshade through a spherical shell. The sphere is located in the spherical shell, and the sphere and the spherical shell share a common center. The spherical shell is fixedly connected to the lampshade. The connection between the spherical shell and the lampshade, the hanging rod, and the spherical shell are all transparent. The lower end of the spherical shell is open to facilitate the rotation of the sphere in the spherical shell when tilted.

[0033] When the tower is in a vertical state, the green laser shines on the diffuse reflector to emit diffuse green light; when the tower is in a tilted state, the green laser shines on the red phosphor to emit diffuse red light as a warning; the upper surface of the lampshade is transparent, which facilitates the diffuse green light and diffuse red light to be emitted upwards.

[0034] The laser module is closed during the day and turned on at night to facilitate aerial photography by satellites and drones. It also serves as a marker for the tower to prevent pedestrians and vehicles from accidentally colliding with it.

[0035] The beneficial effects are as follows:

[0036] The sphere and the spherical shell share a common center, and the sphere can rotate in all directions within the spherical shell. At the same time, this rigid connection ensures the stability of the position of the diffuse reflector and the red phosphor, and the diffuse reflector and the red phosphor are always suspended vertically. Furthermore, the lower end of the spherical shell is open, and the size of the lower end is limited, allowing the sphere to rotate within the spherical shell only within a certain angle. If the sphere rotates within the spherical shell at too large an angle, it will exceed the range of the red phosphor that can be irradiated by the laser, resulting in the inability to emit red light. In other words, when the tilt angle is too large, red light cannot be emitted, and an effective warning cannot be provided. Limiting the range of the sphere's rotation angle within the spherical shell can avoid the above-mentioned problem.

[0037] The connection between the spherical shell and the lampshade, the hanging rod, and the spherical shell are all transparent, ensuring that this rigid connection will not block the diffuse reflected light from shooting upward. Most importantly, the sphere has the functions of diffuse reflection and connection at the same time, which can simplify the structure and save costs. Secondly, the intensity of the laser emitted by the laser module is Gaussian distributed from the edge to the center. At the same time, the top and bottom of the sphere are convex, that is, the thickness of the diffuse reflector corresponding to the middle in the laser direction is greater than that of the edge, and is also approximately Gaussian distributed. The diffuse reflector in the middle part can further diverge the laser, and the light is more divergent to the left and right sides of the diffuse reflector, thereby weakening the luminous intensity in the middle, avoiding the excessive intensity of the light emitted directly upward to affect the pilot, making the green light emitted from the diffuse reflector uniform, extending the service life of the diffuse reflector, and better identifying the tower.

[0038] When the tower is in a vertical state, the device emits green light; when the tower is in a tilted state, the device emits red light as a warning. The emitted light is diffuse reflection, which can prevent the laser from shooting directly upward and affecting the pilot. At the same time, the overall direction of light emission is toward the sky. The difference between green and red is obvious, which is convenient for satellite and drone photography and identification.

[0039] When the tower is in a vertical state, the diffuse reflector emits green light diffusely reflected in all directions. The lower surface of the diffuse reflector is higher than the upper surface of the red phosphor. That is, there is a certain distance between the diffuse reflector and the red phosphor, which can reduce the red light generated by the green light entering the red phosphor. This ensures that the tower basically does not emit red light when it is vertical, and only emits obvious red light when it is tilted. The warning signal is obvious.

[0040] When the diffuse reflector emits green light, it can indicate that the tower is in a vertical state and can also serve as a sign of the tower at night to prevent pedestrians and vehicles from accidentally hitting the tower, achieving multiple goals at one stroke.

[0041] The laser module is turned off during the day and turned on at night. Firstly, it can save electricity. At the same time, the tilt warning signal is more obvious at night, and satellite and drone photography is clearer. Secondly, since the tilt of the tower is usually a slow process that accumulates day by day, only issuing the tilt warning signal at night is sufficient to monitor the tilt change process and issue the warning signal in time.

[0042] The inner diameter of the circular ring is larger than the diameter of the green laser spot; and the transverse width of the diffuse reflector is equal to the inner diameter of the circular ring.

[0043] The beneficial effect is that when the inner diameter of the ring is larger than the diameter of the green laser spot, the green laser will not irradiate the red phosphor within a certain tilt angle of the tower, so a certain tilt angle is allowed, which is in line with the actual situation (if the inner diameter of the ring is equal to the diameter of the green laser spot, then as long as there is a slight tilt, the green laser will irradiate the red phosphor and emit red light, which is too strict and does not conform to the actual situation); the lateral width of the diffuse reflector is equal to the inner diameter of the ring, that is, there is no lateral gap between the diffuse reflector and the red phosphor, and the green laser will at least enter one of the above-mentioned two, avoiding the laser being directly emitted upwards and affecting the pilot.

[0047] The beneficial effect is that the solar module solves the power supply problem of the green laser module. At the same time, compared with ordinary light sources such as LED, laser lighting has high luminous efficiency, consumes less energy at the same brightness, and can extend the time of the identification tower at night.
