BACKGROUND OF THE INVENTION
The present invention generally relates to inspection of high mast structures typified by high mast lighting towers and more particularly to a unique inspection system and method.
High mast towers are tall, reaching heights of several hundred feet, thus creating a problem of manually inspecting the upper portions of the tower for structural integrity including, inter alia, weld cracks, corrosion, straightness, loss of protective surface finish, dents, punctures, and other structural damage or weakness. Practitioners required to inspect a tower are either required to view the tower from a ground location using unaided eyesight, binoculars or a telescope, a method that does not allow a significantly close inspection of the tower for flaws, or they are required to be raised in a bucket to a higher level to perform a similar analysis, which can be very dangerous and such buckets rarely can reach the upper regions of the high mast towers. These methods of inspection more often are expensive, dangerous, and ineffective.
Other reported experimental methods of inspection involve robotic devices capable of independently climbing a high mast tower. Such inspection methods, while providing closer and more level views of the structure, are problematic in several respects. Existing inspection robots only enable inspection of one view of the tower. Thus, several trips up and down the-structure usually are necessary for a full inspection.
Magnetic elements enable these robots to move up and down the structure. Thus, a problem arises when the high mast structure is constructed out of a non-magnetic material and the robot is not capable of climbing the tower. Magnetic adhesion to the tower also limits the weight capacity of the robots, as they often cannot carry all of the desired equipment up the tower. Such robots, beyond containing an already expensive inspection system, also must provide motion and climbing capabilities; thus, adding a great deal of further expense to the system.
A need arises to provide for inspection of high mast towers and other very tall structures that is effective and provides for a level of inspection of a substantial portion of even the tallest high mast towers and other structures, while at the same time avoid being time intensive, prohibitively expensive, or inherently dangerous to practitioners utilizing it. Since most high mast maintenance people are not well trained in crack analysis and operation of highly sophisticated electronic equipment, a desired system would be very simple to use and require little extended education for the operator. It is to such a system that the present invention is addressed.
BRIEF SUMMARY OF THE INVENTION
For purposes of this application, upright structures typified by high masts or poles, such as support light rings, are inspected for an adverse surface condition, such as a flaw, defect, crack, corrosion, erosion, abnormality, irregularity, or other deviation that compromises the integrity and/or functionality of the pole, eventually requiring repair and/or replacement. Such surface conditions often will be referred to as an “anomaly” herein for convenience and not by way of limitation. By “mast” is meant a generally vertical or upright structure, which in the vernacular often is referred to as a pole, tube, rod, shaft, flagstaff, post, wand, tower, or similar upstanding structure. Mast, then, is to be interpreted broadly in accordance with the intent of the disclosure set forth herein.
An inspection system for removably mounting to a platform movable in relation to a generally upright mast for inspection of the mast has a mounting support assembly removably fixable to the platform. A detector device is carried by the mounting support assembly for scanning the mast and collecting mast scanned information. A power supply is carried by one or more of the mounting support assembly or the detector device and is connected to the detector device. A communications device is carried by one or more of the mounting support assembly or the detector device and is connected to the detector device for receiving and relaying the collected mast scanned information.

DETAILED DESCRIPTION OF THE INVENTION
The inventive inspection system can be used to check one or more of the following exemplary mast defects: weld cracks, spot loss of galvanization, dents, tears, corrosion (rust), buried foundations, missing/loose nuts, missing/loose access covers, graffiti, and the like. Such inspection system also provides storable and retrievable data files depicting the condition of the mast (including surface condition). The novel inspection system interfaces with a database that includes mast identification (including GPS location). The database created can be used, inter alia, to establish a baseline of a “healthy” mast following initial installation. The database also can be used to create a report establishing the changes/differences between the current inspection and all prior inspections. Moreover, the inventive inspection system is portable and quite usable by current maintenance mast inspection personnel. The novel inspection system, then, is cost effective.

In an embodiment, the processor may include the following algorithm for purpose of inspecting a crack or flaw on a structure (e.g., pole): receive the actual width of the base of the structure (e.g., pole); receive the distance between the base of the structure (e.g., pole) to the crack or flaw, receive the actual width of the structure (e.g., pole) at the crack or flaw; receive the crack points or flaw points (as referenced as 1710, 1720, and 1730) and width points (as referenced as 1740 and 1750) data according to the locations illustrated in FIG. 10(B) so as to provide “screen image data”; and calculate the actual dimensions of the crack or flaw based on the relationship between the “screen image data” pole width with the actual pole with at the crack or flaw. A benefit of this method is that all crack or flaw measurements can be performed either in the field or at remote location (e.g., home office or satellite location) after the field data have been collected.
In an embodiment, the following method may be implemented:

    
    
        1. Utilize a measuring device, such as tape, laser, or any type of distance determining device to measure the actual width of the base of the pole;
        2. Utilize an ultrasonic distance measurement device or manual measurement (or other automated device) to measure the distance from the base of the pole to the crack or flaw;
        3. Calculate (e.g., via software) the actual width of the pole at the crack or flaw, which may be accomplished from knowledge of the pole taper or other information;
        4. Calculate (e.g., via software) the screen image dimensions of the crack or flaw, as shown in FIG. 10(B) as references 1700, 1720 and 1730 (for example), and entered accordingly, as compared to the screen image width of the pole, as shown in FIG. 10(B) as references 1740 and 1750 (for example), and entered accordingly; and
        5. Calculate (e.g., via software) the actual dimensions of the crack or flaw based on the relationship between screen image pole width (e.g., FIG. 10(B))and actual pole width at the crack or flaw.
        6. Using only two measured pieces of data, and the manufacturer supplied pole taper specifications, the software (e.g., prototype LABVIEW®-based software program or other available programming languages) produces-crack or flaw dimensions (height and width).

A benefit of this method, but not limited thereto, is that all crack measurements can be performed either in the field or at the home office after field data have been collected.

The following disclosure is of a commercially available embodiment of the disclosed high mast inspection system.
Camera Pod Assembly
Referring now to FIG. 11, a camera pod assembly, 8, includes a power supply, camera pod, mounting bracket assembly, and wireless communication transceiver. The camera pod assembly is adapted to be affixed to luminaire ring 1020 of a high mast light tower with the mounting bracket assembly. Referring to FIG. 11, essentially, camera pod assembly 8 includes a camera pod, 10, which includes a still/video camera remotely controlled (pan, tilt, zoom, and focus) and which is powered by a power source, 12 not seen in FIG. 11), which suitably is a rechargeable battery. Camera pod 10 is removably affixed to a bracket assembly, 14, which can be quickly connected/disconnected to luminaire ring 1020 with a bracket, 16, which conveniently operates with a “thumb screw”, 17, hand operable to quickly connect and disconnect camera pod assembly 8 to luminaire ring 1020 or any other component of a light ring assembly. A variety of other quick connect/disconnect designs can be envisioned and it matters only that a service technician can readily operate the connect/disconnect assembly quickly and that it reliably stay connected. Finally, camera pod assembly 8 carries a wireless communications transceiver and antenna (not seen in the drawings but self-contained within camera pod 10) for transmitting the camera-captured images (or other detector outputs) to a near or remote receiver/transceiver and for receiving signals for operating (e.g., pan, tilt, zoom, and focusing) the camera. The particular camera pod illustrated has such wireless communications transmitter built into it; although, a separate such unit can be provided. A direct-wired configuration could be used for this and for other related applications.
While a battery associated with each camera pod currently is contemplated, the operator can connect a single battery or power source carried, for example, by one of the camera pods to the other camera pods for power. Alternatively, other power sources, such as, for example, solar collectors, fuel cells, or the like, may find utility for powering the camera pods and such other power sources are within the scope of the present invention.
Typically, between 3 and 4 camera pod assemblies are used for any given mast being inspected to ensure a complete 360-degree view of the structure. The number of cameras is an input variable to the recorder software (see below). As illustrated in FIG. 11, an Internet Protocol (IP) based camera is provided with its own power source and an IEEE 802.11 wireless transceiver. Camera control and images are sent digitally through the wireless network. Low-level wireless protocols are auto-configuring. Wireless PC card transceivers with small 1/4 wave diverse antennas are used in the camera pods.
Most high mast lamping systems lend themselves to either three or four camera pod assemblies, depending upon the number of luminaires (lamps). Regardless, it is desirable to view all 360° circumference of the pole so that the entire exterior surface can be inspected and recorded. In a 3-camera system, each camera has the potential to view its own 120° sector of the, pole with some overlap with the adjacent cameras. In a 4-camera system, each camera has the potential to view its own 90° sector of the pole with significant overlap, which is slightly better in that a flatter image is viewed with less distortion. Cameras also may be zoomed in so as to have as little image overlap as possible and to yield images with better definition of the pole surface.
High Mast Viewer/Transceiver
FIG. 12 shows the MastCheckTM viewer screen. Images recorded using the MastCheckTM recorder (See FIG. 14) are presented. From one to four images may be shown. The images may be played back, stopped, and manually viewed frame by frame. Frame numbers are recorded with the image and are displayed for reference purposes. Images may be enlarged, edited, entitled, and/or saved as individual or sets of images.
Global Positioning System (GPS) information, showing the pole location, taken at the time of recording is shown in the lower left. The recording operator's comments are included in the bottom center and the crack analysis section on the lower right.
The host recorder workstation (laptop computer) uses a battery powered wireless access point (AP) for all communications with the cameras. These form a network that uses a fixed architecture with IP addresses. Low-level wireless protocols are auto-configuring. The workstation AP also has a high gain panel type diversity antenna to insure a quality signal, and high data throughput. This is placed near the base of the pole or on the maintenance vehicle aimed upward at the cameras.
Crack Analysis Help Screen
The current commercial version utilizes the crack analysis regimen, as described above in connection with FIGS. 10A and 10B, and the description thereof.
High Mast Recorder/Transceiver
FIG. 13 shows the MastCheckTM recorder screen. Images are recorded from one up to four wireless camera pods (across the top). All of the images are recorded independently or at the same time. The recorder also may be paused during the recording. Frame numbers are recorded with the image and are displayed for reference purposes.
Global Positioning System (GPS) information, showing the pole location, is recorded at the start of recording and is shown in the lower left. Pole information is entered and recorded for use in later analysis. The recording operator may also make general comments about the recording. Record control is in the lower right of the screen. A standard MS WINDOWS or similar directory holds all of the recorded data. Comments and pole info are saved at the end of the recording.
Communication Block Diagram for the Inspection System
The block diagram of FIG. 7 was simplified for a commercial version of the disclosed high mast inspection system, as shown in FIG. 14. A controller/processor, 40, drives a computer interface/graphic user interface or display, 42, enabling the operator to visualize the data generated by the detector device. Controller/process 40 can be located remote from the mast poles being surveyed, though it can be carried along with the operator in the field. Auxiliary device(s) (GPS, for example), 43, can be inputted directly into controller/processor 40, if desired.
A transceiver/router, 44, optionally can be used to transmit data to controller/processor 40 and to receive instructions from controller/processor 40. A transceiver, 46, detector, 48, and auxiliary device(s) 43, often are a single unit, such as camera pod assembly 8; although, separate units can be used. Any or all of the communication between any or all of the devices in FIG. 15 can be via hard wire and/or wireless communication.
Functional Flow Diagram for the Inspection Operation
The functional flow diagram for the operation of the inventive inspection system is set forth in FIG. 15. Functional inputs include, inter alia, user inputs, block 51; camera input, block 52; GPS input, block 53; and the pole scan, block 54. The functional inputs become acquired data, block 55, which are stored, block 56. The stored data in block 56 can be outputted to a computer or similar display/analysis device for becoming inspection data, block 57.
The inspection data in block 57 also can be inputted along with stored data from block 57 for playback and analysis, block 58, to determine whether an anomaly has been detected, decision block 59. If no anomaly is detected, an inspection report is completed, block 66, which is recorded in a database, block 67, and the inspection is completed (ended). If, however, an anomaly is detected, a determination as to whether the anomaly is of concern is made at decision block 60. If the decision is made that the anomaly is not of concern, the anomaly is recorded, block 61, and the inspection report is made, as described before.
If the anomaly is of concern, a determination as to whether to put the anomaly on watch status, decision block 62, is made. If no immediate watch is required, the anomaly is cataloged for note at a future inspection, block 63, and the inspection report is made, as before. If the watch decision is positive, then an action watch is created, block 64, and a next inspection of the anomaly is made, block 65, and this action/decision is recorded on the inspection report.
The foregoing functional flow diagram establishes a baseline for existing poles and crack data and other characteristics such as, for example, corrosion collected for other poles, an opportunity exists for monitoring the progress of cracks and other characteristics and employing predictive algorithms for pole maintenance and/or replacement. While such analytical tools have not yet been developed, the inventive inspection system now will enable the skilled artisan to develop and apply these and other analytical tools to high mast poles.
While the invention has been described with reference to various embodiments, those skilled in the art will understand that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope and essence of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims. All citations referred herein are expressly incorporated herein by reference.
