| 摘 要： | 针对现有液压支架电液控制系统缺乏支架运行状态远程监测功能的问题,开发了一种基于双RS485总线的液压支架运行状态监测系统。该系统采用增强型RS485串口通信方式,数据传输速率达10Mbit/s;采用双RS485总线通信模式,可并行执行在线监测和远程控制任务;硬件电路设计采用光耦隔离电路、防高压侵入电路和故障保护电路等抗干扰措施,通过了GB/T 17626.5—1998中的浪涌(冲击)抗扰度试验。实验室及现场调试结果表明,该系统实现了液压支架运行状态的远程在线监测功能,实时性及抗干扰能力强。

| Abstract: | To solve problem of lacking remote monitoring function of running status in existing electrohydraulic control system for hydraulic support,a running status monitoring system for hydraulic support based on dual RS485buses was developed.In the system,an enhanced RS485serial communication mode is used with data transmission speed of 10 Mbit/s.Dual RS485buses communication mode is used for collateral execution of online monitoring and remote control.Some anti-interference measures are used in hardware circuit design including opto-coupler isolation circuit,high voltage intrusion prevention circuit and fault protection circuit,which has passed surge immunity test according to GB/T 17626.5-1998.The test results in laboratory and field show that the system realizes remote and online monitoring of running status of hydraulic support with strong real-time performance and anti-interference performance. |
