Photovoltaic power generation is a clean, renewable energy source that uses solar radiation to generate electricity directly, and is widely used in all areas of production and life. When PV power is supplied at the same time as other power sources, there is a possibility of "solar abandonment". This paper is dedicated to solving the problem of "solar abandonment" caused by grid conflicts. Distributed photovoltaic power generation has a broad development prospect in China, and its power generation cost is lower than that of traditional power sources. As the PV power generation market continues to expand, power system reliability, stability and economy have become one of the important indicators to measure whether distributed PV power generation operates and develops safely and reliably, and therefore distributed PV power generation must be scientifically assessed, strictly managed and controlled.

As China's economy and society continue to develop, urbanisation and industrialisation continue to advance, the construction industry is also developing rapidly and the total amount of construction waste is accumulating. The proportion of construction waste in urban waste is increasing, but the utilisation rate is less than 10%, which has a negative impact on society, the environment and resources. At the same time, the shortage of natural sand resources and the rise in sand prices have made the resource utilization of construction waste a hotspot, and the recycling of construction waste in China is difficult. Therefore, the aim of this paper is to research and design a construction waste recycling information system to recycle construction waste, which greatly improves the utilisation rate of construction waste, promotes the transformation and upgrading of the construction industry, and makes an important contribution to the sustainable development of urban society and economy.
Time management is fundamental to an enterprise and can affect its development. An efficient time management system can play an important role in supervising employees and improving the productivity of an enterprise. However, today, an enterprise's working hours management suffers from reliance on paper carriers, poor real-time, data leakage, inefficiency and reliance on local servers. As local servers have limited carrying capacity, adding local servers will disguise the financial pressure on SMEs, increase SMEs' labour costs and have poor energy efficiency, thus failing to meet the man-hour management requirements of modern SMEs and seriously slowing down their development. Therefore, this paper applies the theory and method of cloud environment data technology to design and study a working hour management information system of an enterprise based on cloud environment data technology, which can manage the whole cycle and time of employees, improve the efficiency of employees, effectively control the project planning progress, and greatly enhance the core competitiveness of the enterprise.
With the continuous development of construction projects, people have higher and higher requirements for project quality. Project quality inspection is the basis for measuring whether the project meets the construction standards, and a qualified project quality inspection and evaluation system can play an important role in the full-cycle inspection and management of project quality and supervising enterprises to regulate construction. However, today's engineering quality inspection has problems such as unclear assessment criteria, unintuitive data and slow processing speed, leading to a decrease in the authority of engineering quality inspection, inaccurate assessment and a significant decrease in public trust in quality inspection parties. Therefore, this paper adopts a new data sampling and strict analysis and evaluation, and researches and designs an engineering quality inspection and evaluation system, which is conducive to improving the supervision and management of engineering quality, facilitating engineering quality inspection, and thus reducing construction costs and enhancing the credibility of the quality inspection team. In addition, the design of the system effectively guarantees the quality of the project, avoids construction risks, greatly improves construction safety, and brings a positive impact on the healthy and sustainable development of the construction industry.
Research on carbon cycle and carbon balance has always been one of the hot spots of global attention, and forest ecosystems, as the largest carbon reservoir in terrestrial ecosystems, are of great importance to the global carbon cycle. As an important component of forest ecosystems, the study and analysis of carbon fluxes in coniferous forest ecosystems is key to understanding the impact of global climate change on the carbon cycle. However, traditional carbon flux data management suffers from lack of data and untimely sharing. Therefore, based on the observation of ecosystem carbon fluxes, this paper designs and studies a carbon flux data management information system to unify the data management, improve the processing and analysis of carbon fluxes, provide data support and services for the carbon cycle of coniferous forest ecosystems, and also help predict future climate change trends, which is the key to cope with global changes.
With the accelerated urbanization and rapid socio-economic development, the construction process is also accelerating. Construction workers have more and more influence on the construction, and the effectiveness of construction worker management directly affects the quality and efficiency of the whole project construction. However, the traditional way of managing construction workers has problems such as incomplete information data of workers, difficulty in supervision, weak awareness of workers' safety and frequent safety accidents. Therefore, this paper designs and develops a construction worker management service information system based on IoT technology and effective integration of Building Information Modeling (BIM) and Radio Frequency Identification (RFID) technologies. The system realizes collaborative information sharing, achieves intelligent management of construction workers, improves construction site safety and quality management, and promotes the sustainable and healthy development of the construction industry, which in turn promotes the rapid development of China's economy.

With the continuous development of the Internet, information technology has penetrated into every aspect of our life and work, and it is imperative to promote informationization in the supervision industry. However, at present, China's engineering supervision projects still have problems such as lagging information technology, low transparency of work, untimely filing of archives and low supervision efficiency. Therefore, based on the fast-developing computer application technology and Internet of Things technology, this paper designs and develops the engineering supervision management information system in order to track and monitor the site situation in real time through quality control, schedule control, investment control, contract management, safety management, information management and organization coordination, which is conducive to ensuring the smooth development of engineering projects, promoting the information development of the whole supervision industry and promoting the sustainable development of the construction industry.
