针对城市道路交通控制系统中大容量数据可靠传输的需求,研发出一种面向道路交通状态获取传感器网络的以太网通信方法及其嵌入式硬、软件。硬件设计采用DSP和以太网控制器;协议实现采用简化TCP/IP协议,既能适应硬件的资源约束,又能完成TCP/IP的基本功能,同时在运输层上采用了面向连接的TCP协议来提高传输的可靠性。实验结果表明采用该方法和装置能实现低差错率和高速率的数据传输,证明该方法和相应系统满足道路交通中大容量数据可靠传输的要求。

英文摘要：

In order to meet the requirement of transmission of mass data in urban traffic network, a new kind of embedded Ethernet communication method and device including the hardware ＆ software using traffic state data acquisition were developed. The hardware is based on DSP and Ethernet controller. The existing TCP/IP was simplified under the premise for limited hardware resources. And connection-oriented TCP is used in the transport layer to improve reliability. The results of experiments show that the method and the device can realize the low error with high speed communication. The conclusion is the method and the device can be used in the traffic state data acquisition.
