The concept of the Internet of Things (IoT) was proposed long ago. The term was introduced at an international conference on mobile computing and networking in the late 20th century in the United States. The concept was first proposed by Professor Ashton of the MIT Auto-ID Center while researching RFID technology. He suggested a solution … Read more
Introduction The car parking lock system based on RFID video technology consists of a core circuit board with STM32F103C8T6 microcontroller, an LCD1602 liquid crystal display circuit, an RFID module circuit, a button circuit, and a relay circuit. The relay simulates the car parking entrance lock switch, normally closed to prevent other vehicles from entering. If … Read more
The initial concept of the Internet of Things (IoT) is generally believed to have been proposed by Professor Ashton from MIT’s Auto-ID Center in 1999 during his research on RFID. At that time, it was referred to as a sensor network, defined as: a network concept where any object is connected to the Internet for … Read more
3. BCM System Composition and Control Principles The Controller Area Network (CAN), Local Interconnect Network (LIN), and FlexRay are commonly used automotive buses. The CAN bus is a serial multi-master controller real-time control local area network bus, with synchronous information transmission. The physical layer is a single wire; the architecture consists of one master device … Read more
Power Calculation According to the literature “Self-sensing Passive RFID: from Theory to Tag Design and Experimentation”, the power received by the tag on the Power-Up LinkPR->T (from reader to tag) and the reader’s received power on the Backscatter Link (Backscatter Link) are theoretically given by the formulas: Where:is the power transfer coefficient of the tag … Read more
RFID (Radio Frequency Identification) is a non-contact automatic identification technology that uses radio frequency signals to automatically identify target objects and obtain relevant data. It is widely used in logistics, retail, transportation, healthcare, and many other fields. The following is a detailed introduction from the aspects of technical principles, components, application scenarios, and advantages and … Read more
