安全监控物联网感知层接入设备的硬件设计

A Hardware Design of Access Equipment in Perception Layer of Safety Monitoring IOT

基于一个安全监控物联网的架构设计方案,介绍了一种感知层接入设备的硬件设计实现。完成ARM嵌入式主控系统,硬件连接至接口扩展模块,满足数据采集、数据处理及转发的功能,以单芯片多功能的设计最大程度降低了硬件成本,实现了与大多数传感器的互连,具有可扩展性和可升级性。

This paper introduces an implementation of the sensor layer access devices of IOT（Intemet of Things）,which is based on a safety monitoring system. The design consists of ARM embedded system module and interface expansion module, which are connected by inter-board connector. This design has the functions of data acquisition, data processing and forwarding .The single-chip and versatile design reduced greatly hardware costs, achieved the interconnection with most sensors. The design has scalability and upgradeability.
