MPL-B330P-RJ72AA

DTU全称数据传输单元，在国内目前实际上对 DTU具有更加明确的约定：DTU是专门用于将串口数据通过无线网络进行传送的无线设备，主要就是通过GPRS，CDMA技术来实现通讯，紫金桥软件支持多家DTU设备厂商的产品，包括GPRS DTU 和CDMA DTU。GPRS DTU工作原理：
GPRS DTU主要工作模式为透明传输模式、命令模式、短信模式。 GPRS工作在透明数传模式下，一旦GPRS DTU上电后自动拨号上线，通常在通过GPRS方式下PPP连接的过程中就会被分配一个动态的IP地址。在一个多终端的应用系统中，每个GPRS DTU因此通过GPRS网络获得一个独一的动态IP地址，如果终端要建立与中心数据服务器的TCP连接，那么必须要求中心数据服务器有一个固定的IP地址，或是中心数据服务器IP地址绑定一个动态域名解析，由此终端的GPRS DTU在上线后，主动向有固定IP地址或一个绑定了IP动态域名解析的域名，发送一个自身设备编号、自身动态IP地址以及端口号的注册信息包，用于保持与中心数据服务器TCP链路保持活跃状态。这种为保持与数据中心服务器的TCP链路保持活跃状态的注册包，我们称之为“心跳包”。每当GPRS重新上电，或是应系统地要求被远程唤醒、或根据GPRS DTU配置设定的发送心跳包间隔时间自动上线，GPRS DTU则应自动的向中心发送心跳包信息，告知数据中心服务器其已保持链路正常。
