Embedded systems and web application development are two crucial directions in the rapidly developing computing field. The Python language, known for its simplicity, readability, and flexibility, has a wide range of applications in both fields. This thesis compares Django and Flask, two major frameworks in Python web development, and evaluates their applicability in different scenarios through systematic experiments on Shannon Orange Pie. The study analyzes the differences in response time, development speed, and flexibility. The purpose of this text is to assist developers in comprehending the appropriate scenarios for various frameworks. It aims to provide practical references for developers when selecting the most suitable framework for their projects.
In contemporary society, smart grid technology of which the foundation is substation technology plays a pivotal role in developping national economy. IEC61850 protocol is widely used in power grid technology due to its various advantages. However, many communication protocols still used in industrial fields, leading to that different devices can’t be well compatible with each other which will result in the low utilization rate. MODBUS protocol is a widely used communication protocol in the industrial scope. This paper mainly study the MODBUS RTU and IEC61805, and then design the transformation of the two protocols by means of object-oriented modeling, as well as design Restful API interface to collect data for visualization. Later, this method of conversion can also be applied to the conversion between other protocols, such as DNP3 and CAN protocols, which will accelerate the pace of protocol unification and promote the development of substation automation.
