针对现有煤矿安全监控系统中越来越多传感器支持485／C A N智能通信，分站支持接口个数少、采用单一的微处理器对传感器的数据进行采集，从而导致现有分站组网成本高、数据响应实时性差等问题。提出一种基于 FPGA 的煤矿井下监控分站设计方案。详细介绍分站的软件和硬件总体架构设计；FPGA 关键信号采集和信号处理技术；部分关键电路详细设计；双口 FIFO 完成 FPGA 与 MCU 之间的通信，解决了 FPGA 与 MCU 工作时钟不一致的问题；同时可以采用红外遥控，灵活设置 FPGA 工作参数，完成人机交互等任务。该方案设计的分站具有数据响应实时性好、485接口个数多、布局布线成本低、适用不同传输接口类型的传感器接入监控系统等优点。

In view of more and more sensors support 485/CAN intelligent communication in the coal mine safety monitoring system ,the substation has few interfaces ,using a single microprocessor for sensor data acquisition ,leads to the existing substation network of high cost ,poor real-time data re-sponse problems. The paper put forward a design scheme of based on FPGA monitoring substation of coal mine underground. Detailed introduction of software and hardware architecture of substation de-sign ;The FPGA key signal acquisition and signal processing technology ;detailed introduction some key circuits design ;use the Dual port FIFO to complete the communication between FPGA and MCU , solve the problem of between FPGA and MCU inconsistent work clock ;At the same time can use the infrared remote control ,flexible setting of FPGA parameters to complete the work ,such as human-computer interaction task. The scheme design of the substation has the advantages of good real-time performance ,response data interface layout and wiring ,485 more low cost ,suitable for different transmission interface type sensor access monitoring system.
