| 摘 要： | 基于ARM的温度采集与以太网传输系统重点是实现稳定地采集实时温度、批量传送采集结果。系统采用基于ARM内核LPC2214对温度传感器LM235输出的模拟信号进行采集;用DM9000控制以太网传输采集结果。基于DM9000的以太网传输具有较高的可靠性,适合批量数据传输,并且可实现较远距离通信。此外,为方便调试和扩展,设计串口通信模块和JTAG仿真调试接口模块。最终,实现对温度的实时采集与传输。

| Abstract: | A temperature acquisition and Ethernet transmission system based on ARM is designed,which focuses on the acquisition of the real-time temperature and transmission in batch.The system uses the ARM kernel LPC2214 to acquire the analog signal that comes from the LM235 temperature sensor.The DM900 Ethernet transmission with higher reliability is appropriate for large amount of data transmission and realization of the long-distance communication.In order to facilitate debugging and expansion a serial communicati... |
