摘　　要：针对带式输送机保护系统一旦发生通信故障就停产检修的问题,分析了带式输送机保护系统查询总线和控制总线的特点,结合通信故障原因和机理,提出了分组通信和总线冗余机制。总线冗余机制不改变任何硬件,利用通信迂回链路,保障系统正常通信,同时预警故障位置和类型。通过单条带式输送机保护系统沿线10台设备查询总线多处故障、控制总线单一故障和查询/控制总线复合故障通信试验,解决了系统发生单一故障停产检修的问题,提升了系统通信鲁棒性。Aiming at the problem of stopping production for communication failure in the belt conveyor protection system,this paper analyzes the characteristics of the query bus and control bus of the protection system,and proposes a grouping communication and bus redundancy mechanism based on the causes and mechanisms of communication failures.The bus redundancy mechanism does not change any hardware and utilizes communication detours to ensure normal communication of the system,at the same time to alert the location and type of failures.By conducting communication tests on 10 devices along the single belt protection system,including multiple failures on the query bus,single failure on the control bus,and composite faults on the query/control bus,the problem of single failure stopping production was solved,and the communication robustness of the system was improved.
