摘要

摘要: 针对现有煤矿安全监测系统中信息传输可靠性差、异构数据融合度低的问题，设计了一款面向煤矿井下的多协议融合网关。该网关可同时接入不同协议类型的传感器，将多源数据以以太网协议数据的形式传输到远程服务器进行信息融合。在该网关中，物理层通过不同协议（RS232、RS485、CAN、ZigBee）传输介质和接口接收终端的数据信息;协议层对不同的数据格式进行解封，得到终端用户原始数据;系统层通过任务管理和通信调度完成多类型设备的接入;应用层设计用户函数和调用内核空间的网络层协议进行数据封装，得到以太网协议格式的数据后不需处理就可传送到上级节点，完成网关多类型协议数据到以太网协议数据的转换传输。测试结果表明，该网关可以实现RS232、RS485、CAN、ZigBee等协议数据转以太网协议数据的透明传输，且传输时延集中在15 ms以内，传输数据丢包率低，具有很强的通信可靠性。

Abstract: In view of the problems of poor reliability of information transmission and low fusion degree of heterogeneous data for coal mine safety monitoring system, a multi-protocol fusion gateway for underground coal mine was designed. The gateway can be connected to sensors with different protocol types at the same time and transmit multi-source data to remote server in the form of Ethernet protocol data for information fusion. In the gateway, physical layer receives data information of the terminal through different protocols (RS232, RS485, CAN, ZigBee) transmission medium and interface. Protocol layer de-archive different data formats to obtain original data of the end user. System layer completes access of multiple types of devices through task management and communication scheduling. Application layer designs user function and calls the kernel space network layer protocol for data encapsulation to obtain the data in the Ethernet protocol format, the data can be transmitted to the upper node without processing, so as to complete conversion and transmission of multi-type protocol data to the Ethernet protocol data of the gateway. The test results show that the gateway can realize transparent transmission of RS232, RS485, CAN, ZigBee protocol data to Ethernet protocol data, and the transmission delay is concentrated within 15 ms, the packet loss of transmission data is extremely low, so the gateway has a strong communication reliability.
