新型自动气象站故障检测方法

摘要

The new automatic weather station is designed on the basis of the current advanced international CAN bus technology.It adopts embedded Linux operating system,which can freely select the desired station sensors according to the needs of the station and solve the problems that the current automatic weather station systems are unable to extend new elements.So the collectors and sensors of different manufacturers and different types can be integrated into a new automatic weather station.The new automatic weather station is very different from the previous generation in hardware and software design,and its fault detection methods and procedures are also different from the previous one.The new station can directly use the log and the commands to find faults,combining the traditional substitution method and measuring method to determine the fault location,which is simple, convenient and greatly reduces the maintenance workload.%新型气自动气象站是根据当前国际先进的CAN 总线技术进行设计的，采用 Linux嵌入性操作系统，可结合台站需要自由选择所需传感器，解决当前自动气象站系统无法扩展新要素的问题，使得不同厂家不同型号的采集器和传感器都可以统一集成到新型自动气象站中。新型自动气象站和上一代自动气象站的软硬件设计架构有很大区别，其故障检测方法步骤也与以往有所不同，新型自动气象站可以直接利用日志和命令来查找故障，结合传统的替代法和测量法判断故障部位，简单、方便、快捷，可大大提高维护人员的工作效率。
