DESC:FIELD
The present disclosure relates to the field of positioning of posts. Particularly, the present disclosure relates to a GNSS based post positioning arrangement and a method thereof.
DEFINITIONS
As used in the present disclosure, the following terms are generally intended to have the meaning as set forth below, except to the extent that the context in which they are used indicates otherwise.
Global Navigation Satellite System (GNSS): The term “GNSS” used hereinafter in the complete specification refers to a satellite navigation system that uses satellites to provide autonomous geo-spatial positioning. The GNSS allows GNSS receivers to determine their location (longitude, latitude, and altitude/elevation) with high precision (within a few meters).
Real Time Kinematic (RTK): The term “RTK” used hereinafter in the complete specification refers to a technique used to enhance the precision of position data derived from Global Navigation Satellite System (GNSS).
These definitions are in addition to those expressed in the art.
BACKGROUND
Typically, photovoltaic (PV) modules are mounted on a module mounting structure (MMS) that is supported on posts. During construction phase, the post is hoisted using a jig within a predrilled hole of diameter larger than the cross-section of the post.
All posts corresponding to an array of photovoltaic modules are required to be aligned linearly within a specified degree of accuracy with respect to each other. Any deviation in the alignment may cause difficulty in installation of MMS and also place residual stresses in the mounting structure. This is detrimental to the MMS and photovoltaic modules, and not only causes difficulty in constructing solar parks but also affects the overall performance and life span of a solar plant (i.e. <25 years). Further, multiple iterations are required for accurately positioning the post within the pre-drilled hole using conventional approaches/techniques which involve a total station and a manual alignment.
There is, therefore, felt a need of a GNSS based post positioning arrangement and a method thereof that alleviates the abovementioned drawbacks of the conventional construction vehicles.

Typically, a photovoltaic system is a power generator that is designed to generate and supply usable solar power by means of photovoltaics (PV cells). The photovoltaic system consists of an arrangement of several components that includes photovoltaic modules for absorbing and converting sunlight into electricity, a solar inverter to change the electric current from DC to AC, as well as mounting, cabling and other electrical accessories for set up of the photovoltaic system. A solar power plant is a large-scale photovoltaic (PV) system that is designed to supply power into the electricity grid.
In ground-mounted solar plants, the PV modules are supported using posts. The principal loads that are required to be supported are vertical or compression loads from the weight of the modules, and the uplift or tension load caused by the wind.
Figure 1 illustrates a side view of an array of photovoltaic modules 102 supported on posts 108. Figure 2 illustrates a front view of the array of photovoltaic modules 102 supported on posts 108.
Circles represent the location of the posts 108 that are embedded into ground 106 after accurate drilling/ ramming/ screwing/concrete piling. The positional accuracy of the posts 108 is critical in order to ensure committed generation of power. Conventionally, to achieve the positional accuracy of the posts 108, the position where the posts 108 are to be positioned are marked on the ground 106 with the help of a differential global position system (DGPS) by referring to a design file prepared in a computer-aided design (CAD) program. Each staked/pegged position is then used by a machine operator to position the drilling/auguring machine to make foundation pits (not specifically shown in the figures). Typically, the post 108 to be installed in the pit is rigged to a jig 312 (shown in figure 3) which has screw adjustments to position the post 108 and provide rigidity, thereby ensuring stability during concrete pouring process.
Typically, the posts 108 on either ends of the module mounting structure 104 are first positioned as per the coordinates depicted in the design file. If the foundation pits are drilled correctly, then the center of each of the posts 108 should align with the center of the corresponding foundation pits. All other posts 108 that are required for supporting the array of photovoltaic modules 102 are positioned using the jigs 312 and string. Additionally, using the combination of line-of-sight, string, tape measure, and total station the posts 108 are fixed.
Referring to Figure 3 and Figure 4, the present disclosure envisages a GNSS based post positioning arrangement 300 (hereinafter referred as “arrangement 300”). The envisaged arrangement 300 employs a low cost GNSS real time kinematic (RTK) technique. The RTK is a differential GNSS technique used in enhancing an accuracy of a positioning data derived from the GNSS in a real-time by utilizing a fixed base station 306 for sending out corrections to a moving receiver.
The post positioning arrangement 300 of the present disclosure comprises a GNSS rover 302, a jig 312, a base station 306, and a computing device 308 with storage either on cloud or local.
The jig 312 is configured to securely hold the post 108 in a field. In an embodiment, the jig 312 is configured to securely hold the post 108 in a drill pit 310. In another embodiment, once the drill pit 310 is drilled, the post 108 is jacked using the jig 312 and securely held in the drill pit 310.
The base station 306 is mounted at a pre-determined location in the field. In an embodiment, the base station 306 is positioned in the proximity of the site/field of operation where the post 108 is to be mounted. The base station 306 is configured to generate a location correction data based on its present location, and is further configured to broadcast the location correction data. In an embodiment, the base station 306 is configured to broadcast real time kinematic (RTK) information to the GNSS rover 302. In another embodiment, the correction data is transmitted wirelessly, i.e. by radio transmission to the GNSS rover 302 for reduced latency and reliability of the communication.
In an embodiment, the base station 306 includes a repository 306a, a location detection unit 306b, and a digital differentiator 306c. The repository 306a is configured to store a pre-determined present location of the base station 306. The location detection unit 306b is configured to determine GNSS identified present location of the base station 306 by cooperating with the GNSS satellite constellation. The digital differentiator 306c is configured to cooperate with the repository 306a and the location detection unit 306b to compare the GNSS identified present location of the base station 306 with the pre-stored present location to generate the location correction data. In an implementation, the digital differentiator 306c is implemented using one or more processor(s).
Typically, DGNSS technique is an enhancement to a primary GNSS system that consists of the determination of the GNSS position for an accurately-surveyed position known as a reference station. Given that the position of the reference station is accurately known, the deviation of the measured position to the actual position and more importantly the corrections to the measured pseudo ranges to each of the individual satellites can be calculated. These corrections can thereby be used for the correction of the measured positions of other GNSS user receivers.
In an embodiment, the base station 306 may be configured to broadcast the GNSS rover 302 over an unlicensed radio frequency band.
The GNSS rover 302 is securely mounted on the post 108, and is configured to:
• determine an approximate location for the post 108 by cooperating with a GNSS satellite constellation;
• receive the broadcasted location correction data from the base station 306; and
• determine the precise location of the post 108 based on the received location correction data and the determined approximate location.
In an embodiment, the positioning arrangement 300 includes an attaching means 304. The attaching means 304 is mounted on an operative top portion of the post 108. The attaching means 304 is configured to facilitate secure mounting of the GNSS rover 302 on the operative top of the post 108. In an embodiment, the attaching means 304 is a mounting cap. In another embodiment, the attaching means 304 is made of plastic.
In an embodiment, the GNSS rover 302 is configured to communicate with the GNSS satellite constellation to receive and digitally process the signals received from the GNSS satellite constellation to determine the approximate location of the post 108.
The computing device 308 is communicatively coupled to the GNSS rover 302 to receive the precise location of the post 108, and is further configured to identify deviation of the post 108 from the target location based on the determined precise location of the post 108 by the application. Further, based on the identified deviation of the post 108 the operator displaces and secures the post 108 at the target location.
The computing device 308 is communicatively coupled to the GNSS rover 302 to receive the precise location of the post 108. The computing device 308 is further configured to display the identified deviation of the post 108 from the target location based on the determined precise location. In an embodiment, the application of the computing device 308 is configured to display the identified deviation which represents:
• bearing to the target location; and
• distance of the post 108 from a target location to an operator to facilitate positioning of the post 108.
In an embodiment, the computing device 308 includes a memory, an analyzing unit, and a notification unit. The memory is configured to store a design layout indicating the target location of the post 108, i.e., the target location where the post 108 is to be exactly mounted/positioned. The analyzing unit is configured to cooperate with the memory. The analyzing unit is configured to receive the precise location of the post 108, and is further configured to determine the bearing to the target location and the distance of the post 108 from the target location based on the received precise location and the design layout having target location. In addition, the computing device is also configured to capture and display the performance of multiple teams. The notification unit is configured to cooperate with the analyzing unit to receive and notify an operator about the identified deviation of the post 108 from the target location. In an implementation, the analyzing unit is implemented using one or more processor(s).
In one embodiment, the computing device 308 is selected from the group consisting of a mobile, a tablet, a smartphone, a laptop, a computer, a desktop, a personal digital assistant (PDA), and a portable electronic device.
Further, based on the information provided by the computing device 308, the jig 312 and therefore the post 108 is moved in the direction of the target location, thereby providing positional accuracy. Thus, the positioning arrangement 300 of the present disclosure precisely determines the position of the post 108 and facilitates accurate positioning of the post 108 as per the design location. Typically, the positional accuracy of the post 108 as determined by the arrangement 300 of the present disclosure is +/-7 mm.
Once the post 108 is mounted at the target location, the attaching means 304 and the GNSS rover 302 are detached from the post 108, and are reused with another post 108.
The usage of GNSS based post positioning arrangement 300 of the present disclosure reduces the number of iterations required for aligning the posts 108.
The positioning arrangement 300 of the present disclosure can be used in other areas where large number of posts 108 is required to be erected. The positioning arrangement 300 may be used for any activity where latitude and/or longitude position are required for installation of utility solar plants. Additionally, the positioning arrangement 300 may be used in mining industry for creating blast holes as per mine plans or in civil industry for ground reinforcement. Typically, the envisaged positioning arrangement 300 of the present disclosure can be wherever a total station (TS) is used for marking a position on the ground 106, thereby eliminating the need of a surveyor.
In one embodiment, the application installed in the computing device 308 is configured to display utilization and productivity of contractors employed to perform the task of mounting post 108. In another embodiment, the application of the computing device 308 is configured to provide different analysis based on the position and mounting of the posts 108.
