摘要
针对市场上诸多的矿用产品,介绍了一种基于CAN总线的无线2.4G读卡器的设计.利用MCP2515作为CAN总线控制器,完成总线的链路层协议,极大地降低了通信对MCU数据处理的要求.该读卡器能够快速准确地定位人员在矿区的位置,具有可靠性高、低功耗、低成本以及使用方便等特点.
This paper introduces the design of a wireless 2.4G card reader based on CAN bus for the need of many mine products in market.MCP2515 is used as CAN bus controller to realize link layer protocol for bus so that the requirement for MCU data processing is reduced greatly.The card reader can rapidly locate the position in mine area,with the characteristics of high reliability,lower consumption,lower cost and easy operation.
