) Ho Chi Minh City, January 1 ,2024 REVIEWER (Sign with full name) ACKNOWLEDGE Firstly, our team would like to express our special gratitude to the faculty of High- Quality Training at the Ho Chi Minh City University of Technology and Education. The opportunity provided by our professors has allowed us to access and develop problem- solving skills, creating a favorable environment for the development of our project. This has enabled us to delve deeper into specialized knowledge and apply it in practical scenarios. Our sincere thanks to PhD.
Le Trong Nghia for his guidance and support throughout the process of completing our graduation project. With his assistance, our team has been able to address various knowledge-related challenges and make improvements during the research phase. Le Trong Nghia has played a crucial role in helping our team successfully navigate the development of our research project. Although our team has completed the project, we acknowledge that there are still shortcomings and limitations in the content and research process.
We eagerly anticipate valuable feedback and guidance from our esteemed professors to further enhance and solidify our specialized knowledge through the refinement of our project. Sincerely thank! Student i ABSTRACT The topic was developed to address the issue of linear planning for charging stations at a specific location, as well as to enhance certain features to better suit users. Linear planning for charging stations helps the electrical system, enabling the selection of the appropriate number of charging stations based on the specific needs of a given location. Additionally, monitoring features for charging stations are integrated into a mobile application, allowing users to easily observe and operate them.
The application includes Google Maps integration to help users easily find nearby charging stations. To achieve the outlined goals, the team followed a series of steps: Stage 1: Generating ideas for linear planning of charging stations and user-friendly features. Stage 2: Calculating and designing the appropriate number of charging stations for a specific location. Stage 3: Integrating RFID code scanning with barcodes on the mobile application to display data.
Stage 4: Storing data in a cloud server and integrating Google Maps into the mobile application. Stage 5: Establishing a connection between the cloud server and the mobile application to create a complete system. The project on linear planning for charging stations has successfully achieved its goals, resulting in the following outcomes: Result 1: The system operates stably, and users can easily interact with the model. Result 2: Linear planning calculations for the specific location of charging stations have been successfully carried out.
Result 3: The mobile application has a user-friendly interface, locating the nearest charging stations through the Google Maps API and accurately displaying the data. This helps users monitor specific information easily. While the system operates stably, there is still room for optimizing the data processing, leading to a certain level of latency in real-world scenario ii LIST OF CONTENT ACKNOWLEDGE. ii LIST OF CONTENT.
