基于单片机和RFID的智能电子关封设计

Intelligent electronic seal design based on MCU and RFID

针对海关物流管理系统需要,本文设计了一套电子关锁系统,用来取代传统的一次性铅封监管方式。首先介绍了融入RFID技术的电子关锁系统的整体设计方案和运行方式,然后对电子关锁的硬件电路设计和检测部分,运算部分,控制部分,通讯等部分进行了阐述,其次对整个电路进行软件编程设计,最后对系统设计中的一些关键问题,包括低功耗、防冲突设计等进行了分析并给出了设计达到的性能。

Aiming at the customs logistics management system, this paper designs a set of electronic lock system, used to replace the traditional way of disposable seal supervision. First introduced the overall design scheme and operation mode of RFID technology into the electronic lock system, then turn to electronic hardware circuit design and testing part, lock operation part, control part, communication part is discussed, followed by the software design of the whole circuit, finally some key questions of system design. Including the design of low power consumption and anti conflict are analyzed and presented to the performance design.
