为了使煤矿井下基于ModBus总线、CAN总线和以太网3种不同协议的设备和监控系统能够互通互联,形成综合的自动化系统,提出了一种嵌入式多协议转换器的设计。其硬件使用了32位微控制器LPC2292,软件设计使用了μC/OS-Ⅱ嵌入式实时操作系统,可以同时实现ModBus协议、CAN协议和TCP/IP协议等3种协议之间的相互转换,将煤矿井下基于这3种现场总线协议的设备和监控系统的数据进行相互转换和实时透明传输。
In order to make the equipment and monitoring system based on ModBus bus, CAN bus and Ethernet with three different protocols in coal mine to be interconnected and form an integrated automation system, an embedded multi-protocol converter design is proposed. Its hardware uses a 32-bit microcontroller LPC2292, the software design uses μC / OS-Ⅱ embedded real-time operating system, you can simultaneously achieve ModBus protocol, CAN protocol and TCP / IP protocol conversion between the three protocols will be Coal mine based on the three kinds of field bus protocol equipment and monitoring system of data conversion and real-time transparent transmission.
