带式输送机故障定位系统网关的设计

以带式输送机故障定位系统为应用背景,提出了一种基于STM32F103VE微处理器的CAN总线与Profibus-DP总线网关的设计方案。该网关在CAN网络中作为一个CAN通信节点,在Profibus-DP网络中作为一个从站;带式输送机沿线分布若干个CAN检测节点,每个节点负责检测其段内的4种传感器设备采集的实时数据,如果检测到故障信息,CAN检测节点就会向网关发送故障信息报文,网关接收CAN检测节点发送的报文并进行存储;当网关与Profibus-DP主站连通后,作为Profibus-DP从站的网关可以通过查询方式把故障信息报文传送到Profibus-DP主站中,从而实现故障定位功能。实际应用表明,该网关运行稳定、可靠,实现了带式输送机故障定位系统中CAN总线及Profibus-DP总线的互联。

Design of Gateway in Fault Location System of Belt Conveyor

Taking fault location system of belt conveyor as application background,the paper proposed a design scheme of gateway of CAN bus and Profibus-DP bus based on STM32F103VE.The gateway is used as a CAN communication node in CAN network and a slave station in Profibus-DP network.Several CAN detection nodes are distributed along belt conveyor and each node is used to detect real-time data collected by four kinds of sensors.If fault is detected,CAN detection nodes would send fault message to the gateway which receives and stores message sent by CAN detection nodes.When the gateway is connected with Profibus-DP master station,the gateway is used as Profibus-DP slave station to send fault message to Profibus-DP master station through query mode to realize fault location function.The actual application showed that the gateway runs stably and reliably and realizes interconnection between CAN bus and Profibus-DP bus of fault location system of belt conveyor.
