For many types of electrical equipment interface and various of field bus communication co-exist in the current coal mine,a multi-interface communication manager had been designed.The manager used STM32 chips as the core processors to achieve signal conversion between the various types of interface%针对目前煤矿井下电气设备的接口种类多、多种现场总线通信方式共存的现状,提出了多接口通讯管理器的硬件设计思路。该管理器以Cortex STM32芯片为核心处理器,可实现各类接口之间的信号转换、互联。
