基于FPGA的煤矿安全监控系统监控分站的设计

针对煤矿安全监控系统中的监控分站采用单一微处理器采集传感器数据而导致的实时性差的问题,提出了一种基于FPGA的煤矿安全监控系统监控分站的设计方案,详细介绍了该监控分站的软、硬件设计。该监控分站采用A3PE600系列FPGA完成传感器信号的数据采集任务,采用ARM系列MCU完成与FPGA通信、与上位机通信、根据配置信息及传感器数据实现断电及报警控制、人机交互等任务。该监控分站实时性强,可接入多种类型的传感器,并适用于传输接口不同的多种安全监测监控系统。

Design of FPGA-based Substation of Safety Monitoring and Control System of Coal Mine

In view of poor real-time performance of safety monitoring and control system of coal mine because sub stations collect sensors' data by use of single microprocessor,a design scheme of FPGA-based substation was put forward and designs of the substation's software and hardware were introduced in details.A3PE600 series of FPGA was used in the substation to accomplish acquisition of sensors' data,and ARM was used to accomplish tasks of communication with the FPGA and the host computer,control of power-off and alarming according to configuration information and sensors'data and human-computer interaction.The substation has good real-time performance and can connect various of sensors and be used in different safety monitoring and control systems with different transmission interfaces.
