基于CAN总线的嵌入式气象仪器转换器设计

针对目前气象观测站中,不同厂商气象仪器的上位机软件不能彼此兼容,导致一套气象观测站中无法使用不同厂商的气象仪器,无法综合显示和管理不同厂商气象仪器数据的问题,提出了自动气象站气象仪器的通信协议和规则,气象仪器采用该协议规则进行数据通信,上位机集中显示和管理数据,为了验证该方案的可行性和优越性,设计了一种基于CAN总线的嵌入式气象转换器,它是将不同厂商的采集器挂接在总线上,通过转换器对各个厂商的采集器的不同通信标准进行辨识、抽象整合、再次定义,上位机实现综合显示和自适应管理。该系统进行了试用,各项性能测试良好。

Design of embedded meteorological instrumentation converter based on CAN bus

To solve problems that the meteorological stations cannot use data acquisition system of different apparatus of different vendors,and data acquisition of different vendors cannot be integrated display and management,an embedded meteorological converter based on CAN bus is designed,and data acquisition apparatus of different vendors is mounted on the bus,different communication standard of collector of various manufactures are identified,Abstract integration and refined by converter,host computer achieve integrated display and adaptive management.The system enters trial stage,and each performance test result is well.
