BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figure 1 This is a schematic diagram of the plan distribution of the photovoltaic construction site. DETAILED DESCRIPTION

[0031] The invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0032] refer to Figure 1 A method for counting the workload of photovoltaic construction by using a drone includes the following steps: using a drone to inspect and obtain the number A of photovoltaic panels installed, the number B of photovoltaic brackets installed, and the number C of foundation piles erected every day.

[0033] The installation quantity A of photovoltaic panels can be the actual number of photovoltaic panels of standard area installed, the installation quantity B of photovoltaic brackets can be the corresponding number of photovoltaic panels of standard area that can be installed by the photovoltaic brackets, and the erection quantity C of foundation piles can be the corresponding number of installed photovoltaic brackets and converted into the corresponding number of photovoltaic panels of standard area that can be installed. That is, completing the installation quantity A of one photovoltaic panel, the installation quantity B of photovoltaic brackets and the erection quantity C of foundation piles is equivalent to completing the installation of one photovoltaic panel on average.

[0034] The specific steps include:

[0035] Remotely controlled drones are used to obtain feature images above the work site.

[0036] The remote-controlled drone flies above the work site to conduct a panoramic observation, and uses the camera carried by the drone to take a panoramic picture of the work site.

[0037] like Figure 1 As shown in , the area S of the planned site and the area S of the installed photovoltaic panels are extracted from the feature image. A , the area S where the photovoltaic bracket is installed B 、The area of ​​the area where the foundation piles have been set up S C .

[0038] The area S of the planned site corresponds to the number of photovoltaic panels to be installed, so it is different from the actual measured area S of the photovoltaic bracket installation area. B The ratio is equivalent to the ratio of the total number a to the number of photovoltaic panels installed A0, and by analogy, B0 and C0 can be obtained.

[0039] in accordance with Calculate the number of photovoltaic panels installed A0, the number of photovoltaic brackets installed B0, and the number of foundation piles erected C0 that have been completed as of the day, where a represents the total number of photovoltaic panels installed, b represents the total number of photovoltaic brackets installed, and c represents the total number of foundation piles erected.

[0040] Every day, a set of installed quantities A0 of photovoltaic panels, B0 of photovoltaic brackets, and C0 of foundation piles completed as of that day are obtained. The installed quantities A0 of photovoltaic panels, B0 of photovoltaic brackets, and C0 of foundation piles completed as of that day are obtained on that day and the installed quantities A0 of photovoltaic panels, B0 of photovoltaic brackets, and C0 of foundation piles completed as of that day are subtracted from the previous day's completed quantities A0 of photovoltaic panels, B0 of photovoltaic brackets, and C0 of foundation piles to obtain the installed quantities A of photovoltaic panels, B of photovoltaic brackets, and C of foundation piles for that day.

[0041] An observation experiment was used to obtain the equivalent time T1 for one person to install a photovoltaic panel, the equivalent time T2 for one person to install a photovoltaic bracket, and the equivalent time T3 for one person to set up a foundation pile.

[0042] Specifically, observe the time t taken by a group of 5 people to install 10 photovoltaic panels, then T=t / 5*10. After observing multiple groups and taking the average value, we can get the equivalent time T1 for one person to install a photovoltaic panel. Similarly, we can get the equivalent time T2 for one person to install a photovoltaic bracket and the equivalent time T3 for one person to set up a foundation pile.

[0043] Calculate the daily photovoltaic construction workload P:

[0044] P=A*T1+B*T2+C*T3①;

[0045] In formula ①, T1 represents the equivalent time for one person to install a photovoltaic panel, T2 represents the equivalent time for one person to install a photovoltaic bracket, and T3 represents the equivalent time for one person to set up a foundation pile.

[0046] The statistics team submits the daily number of installed photovoltaic panels A, the number of installed photovoltaic brackets B, and the number of foundation piles C. This data is compared with the daily number of installed photovoltaic panels A, the number of installed photovoltaic brackets B, and the number of foundation piles C obtained by remote-controlled drones to determine whether there is false data in the data reported by the personnel.

[0047] It is also possible to compare the daily PV construction workload P with the daily PV construction workload P expected by the engineering task schedule. 预期 , when P<P 预期 When constructing a project, extend the daily working hours of workers or increase the number of workers in order to reasonably control the number of construction workers and the construction market, and better control the construction progress.

[0048] Allocate the number of workers x for installing photovoltaic panels, the number of workers y for installing photovoltaic brackets, and the number of workers z for erecting foundation piles; among which the number of workers x for installing photovoltaic panels, the number of workers y for installing photovoltaic brackets, and the number of workers z for erecting foundation piles satisfy the following formulas ② and ③.

[0049]

[0050] x+y+z=Q ③;

[0051] In formula ③, Q represents the total number of workers.

[0052] In one embodiment, the expected daily photovoltaic construction workload P of the engineering task arrangement 预期 The calculation method is as follows:

[0053]

[0054] In formula ④, M represents the total number of photovoltaic panels to be installed, D represents the expected number of days to complete the project, and η represents the working time unsaturation rate.

[0055] In one embodiment, the daily photovoltaic construction workload P can also be accumulated and summed to obtain the total photovoltaic construction work completion volume P 总 , the total photovoltaic construction work completed P 总 Used to reflect the progress of photovoltaic construction.

[0056] In one embodiment, the working days that do not satisfy the requirement that the number of photovoltaic panels installed A ≤ the number of photovoltaic brackets installed B ≤ the number of foundation piles erected C per day may also be marked.

[0057] In one embodiment, the value of Qt-P may also be judged. When the value of Qt-P is greater than a first threshold, it is judged that the worker's workload is not saturated, where t represents the worker's daily working hours.

[0058] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
