| 摘 要： | 以嵌入式技术应用为背景,介绍了主、从MCU系统的井下数据采集与存储系统.系统工作在数据采集模式下时,主MCU C8051F340主要负责读入双口RAM中的数据,并将其写入电子盘,当系统与PC机相连接时,C8051F340通过USB接口与PC机实现海量存储的通讯.从MCU C8051F340主要负责与A/D芯片的SPI通信,并将与A/D值写入双口RAM.双口RAM主要是实现数据的缓冲,使得系统工作在高速数据采集存储状态.该系统具有低功耗、尺寸小和高速等特点.

| Abstract: | After introducing some applications of embedded technology,introduced oil well massive data collect and store system based on master slave MCU hardware structure.When the system was not connected to the computer,the master MCU took the responsibility for reading the dual-port RAM and writing the data to IDE Flash Disk.Otherwise the master MCU communicated with the computer by USB.The slave MCU took the responsibility for communicating with A/D chip by SPI and writing the data to the dual-port RAM.The system characteristics are low power consumption,small size,etc. |
