摘　　要：监控煤矿运煤皮带与滚动轴之间的摩擦温度。利用双CPU实现高速数据交换和处理,将主控和数据处理等功能分开执行。利用多个红外测温传感器MLX90614,分别固定在各滚轴附近,其简单的SCK和SDA接口,直接连接于CPU的普通I/O口,各自对应一个不同地址,快速完成滚轴温度检测。利用双端口RAM作为共享数据存储器,两个端口有两套完全独立的控制总线、地址总线和I/O数据总线,可独立读/写任意地址单元,两个CPU共享该存储器,提高了系统的数据传输速率。The friction temperature is monitored between coal belt and roller shaft in coal mine.To achieve hign-speed data exchange and processing using double CPU, main control and data processing function are separated.Multiple infared measuring temperature sensor（MLX90614） are respectively fixed on the roller, its simple SCK and SDA interface ,is connected directly to the CPU＇s I/O,corresponded to a different address,to fastly detect temperature of roller.Dual port RAM is shared as data memory,the two ports have two sets of fully independent control Bus,address Bus and the I/Odata Bus,may separate the Read/Write address unit;two CPU share the RAM,it improve the data transfer rate of the system.
