[0023] Figure 2 It is a schematic diagram of the smart construction site system of the present invention. DETAILED DESCRIPTION

[0024] like Figure 1-2 As shown, the specific implementation adopts the following technical solutions:

[0025] Example:

[0026] A method for calculating costs of a smart construction site system for a substation project, comprising the following steps:

[0027] S1. Obtain construction project documents and determine the cost scope of the smart construction site system for the new substation project;

[0028] S2. Obtain the module cost index of the smart construction site system project and calculate the cost based on the equipment usage;

[0029] S3. Calculate equipment support and operation and maintenance costs according to the construction budget standard;

[0030] S4. Calculate the cost of each cost category, summarize the costs of each cost category, and obtain the comprehensive cost of the smart construction site system of the substation project.

[0031] Among them, the system costs include monitoring, identification, safety tools, machinery and instruments.

[0032] Among them, module cost indicators include equipment fees, installation and commissioning fees, supporting civil engineering fees, technical support fees and other fees.

[0033] Among them, the equipment use methods are divided into purchase and leasing;

[0034] The calculation formula for rental equipment usage fee is as follows:

[0035]

[0036] Among them, other costs include daily operation and maintenance costs of the smart construction site system, later dismantling and storage costs of the system, and software costs.

[0037] Among them, the software cost is calculated based on the number of developers and the unit price of each person.

[0038] Among them, the installation and debugging fees include the on-site installation, debugging, on-site wiring, installation and adjustment of wiring of positioning antennas and positioning terminals of the smart construction site system.

[0039] Specific:

[0040] The cost of the smart site system for substation projects includes the purchase (amortization) or leasing of corresponding equipment, installation and commissioning, supporting civil engineering, technical support, operation and maintenance, and subsequent disposal. Among them, the equipment usage fee is calculated according to the amortization principle by comprehensively considering factors such as equipment depreciation, residual value recovery, and project construction cycle. If it is obtained through leasing, the hardware cost is determined by multiplying the leasing unit price by the leasing period;

[0041] The cost of the smart construction site system for the new substation project includes monitoring, identification, safety tools and machinery, instruments, etc. The system costs are amortized based on the current market price of the equipment;

[0042] The module cost index includes the costs of equipment purchase (amortization) or leasing, installation and commissioning, supporting civil engineering, technical support, operation and maintenance, and subsequent disposal. The calculation formula is as follows:

[0043] Hardware costs:

[0044] Smart site cost (obtained through purchase) = equipment cost + material cost + installation and commissioning, demolition cost + construction cost + operation and maintenance service fee;

[0045] Equipment Fee:

[0046] The equipment price level is determined by issuing survey forms, inviting experienced suppliers to quote and calculating the average price after tax. At the same time, the average life method is used to calculate depreciation. According to the "Implementation Regulations of the Enterprise Income Tax Law of the People's Republic of China", the minimum depreciation period of electronic equipment is 3 years (after investigation, the average depreciation period of most electronic equipment is 3-5 years, so this study selects the average depreciation period of 4 years), and considers 5% of the residual value to amortize the equipment;

[0047]

[0048] Among them, the "purchase price" includes 0.7% unloading storage fee; "use time" is determined according to the construction period, use time = construction period (month) * 30;

[0049] Among them, the material cost, on-site installation and commissioning fee (including equipment secondary transfer fee), equipment later removal fee and supporting construction engineering fee of the smart construction site management system are calculated based on the actual survey data and in combination with the "Regulations on the Preparation and Calculation of Power Grid Engineering Construction Budget (2018 Edition)";

[0050] The operation and maintenance service fee refers to the daily operation and maintenance fee of the hardware of the smart construction site management system, which is determined by combining the data reported by experts and manufacturers after issuing the survey form and taking the average value;

[0051] The number of developers invested in the smart construction site system software costs was obtained through investigation, and the unit price level of personnel was referred to the "Notice of State Grid Corporation of China on Printing Workload Measurement Specifications and Application Guidelines for Power Grid Digitalization Projects" (State Grid Interconnection

[2020] No. 606). Finally, the costs of each of the above cost categories were summarized to obtain the comprehensive cost of the smart construction site system for the substation project.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
