针对液压支架电液控制系统运行特点,提出了液压支架电液控制系统急停控制功能整体设计方案,通过基于单线CAN总线的急停通信电路实现了全系统的急停功能,并具有急停触发和解除时的高亮高分贝报警功能,能够在所有支架控制器上显示急停触发位置,对于系统通信故障、支架控制器复位及急停按钮损坏等故障有较好的适应能力,经过功能和性能测试,验证了该方案的可行性。 According to the operation characteristics of electro-hydraulic control system of hydraulic support, the overall design scheme of emergency stop control function of electro-hydraulic control system for hydraulic support is put forward. The system-wide emergency stop function is realized through the emergency stop communication circuit based on single-wire CAN bus, And release high-brightness high-decibel alarm function, to display the emergency stop trigger position on all the stand controller, the system communication failure, the bracket controller reset and emergency stop button failure have better adaptability, through the function and Performance test to verify the feasibility of the program.
