随着矿用监控系统工作站安全生产标准的不断提高,矿用监控系统工作站已逐渐采用CAN总线通信协议取代了原有的RS-485工作方式,但在工作站与监控主机连接的模块中仍存在多种工作方式,这些工作方式都存在一点的缺陷,并在一点程度上影响了矿用监控系统。为了克服这些缺陷,详细设计了CAN接口以及与上位机的USB接口。试运行结果表明,该接口可以便捷稳定的在监控主机和各个监控节点之间交互数据。
With the continuous improvement of mine safety monitoring system workstation safety standards, mining monitoring system workstation has gradually replaced the original RS-485 working protocol with CAN bus protocol, but there are still many modules in the workstations connected with the monitoring host Kinds of work, these work methods have some flaws, and to a certain extent, affected mine monitoring system. In order to overcome these defects, the CAN interface and the USB interface with the host computer are designed in detail. The test results show that the interface can be convenient and stable in the monitoring host and monitoring data exchange between nodes.
