摘要
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 the electro-hydraulic control system of the hydraulic support, the paper proposed the whole design scheme to realize emergency stop control function of the electro-hydraulic control system of the hydraulic support, and the emergency stop of the whole system realized via the emergency stop circuit based on single-line CAN bus. In addition, highlighted and high decibel alarm took effect on emergency stop and release, and emergency stop triggering position displayed on all the support controllers. It possessed excellent adaptability for the faults about system communication, reset of support controller and damage of emergency button, and proved feasible after function and performance test.
