摘　　要：针对国家煤矿安监局关于印发的《煤矿安全监控系统升级改造验收规范》的通知以及AQ 6201—2019中对数字化、抗电磁干扰、巡检周期、异地控制等技术指标要求,设计了基于多总线结构的低功耗全数字光口分站,分站具有RS485、CAN、光口等多种总线结构,重点论述了分站降功耗人机交互关键技术,通过对传统人机交互显示功能进行自主设计,降功耗明显。通过系统送检各项试验测试,分站各项指标均高于标准要求,系统电快速脉冲群抗扰度试验达到了3级A,浪涌4级B,具有电磁兼容等级高、稳定低功耗等特点。In view of the notice issued by the State Administration of Coal Mine Safety Supervision on the acceptance specifications for the Upgrading and Transformation of Coal Mine Safety Supervision and Control Systems, as well as the requirements of AQ 6201-2019 on technical indexes such as digitalization, anti-electromagnetic interference, inspection cycle,remote control, etc., a low-power all digital optical interface substation based on multi-bus architecture is designed. The substation has RS485, CAN, optical interface and other bus structures, and the key technology of man-computer interaction for reducing power consumption in substation are discussed, through the independent design of the traditional human-computer interaction display function, the power consumption is reduced obviously. Through various tests submitted by the system for inspection, all indexes of the sub-station are higher than the standard requirements, and the electrical fast pulse group immunity test of system has reached level 3 A, and the surge level 4 B, with high electromagnetic compatibility level, stable and low power consumption and other characteristics.
