摘要
针对短距离低成本无线传感网络需求,采用VHDL语言设计了一种基于星形拓扑的无线传感网络传感器节点数据收发控制器。设计了以CSMA/CA协议为基础的段距离传感器无线通信传输帧格式,可以极大的减少数据传送的碰撞概率。给出了控制器设计的顶层图,其逻辑控制采用有限状态机完成。对控制器主要模块采用Mentor Graphics公司的Model Sim SE PLUS 6.5软件进行了功能仿真验证。该设计移植性强可快速嵌入其他物联网感知层数据传输控制器的设计中。
In order to meet the needs of short-distance and low-cost wireless sensor networks, a star topology-based wireless sensor networksensor node data transceiver controller was designed using VHDL language. A segment distance sensor wireless communication transmission frameformat based on CSMA/CA protocol is designed, which can greatly reduce the collision probability of data transmission. The top-level diagram of thecontroller design is given, and its logic control is implemented using a finite state machine. The main module of the controller was verified by functionalsimulation using Mentor Graphics＇ ModelSim SE PLUS 6.5 software. This design is highly portable and can be quickly embedded in the design of otherInternet of Things sensor layer data transmission controllers.
