【摘要】：随着射击运动的普及,各类靶场不断发展。传统的数据管理方式不仅效率低下,而且数据的准确性、可靠性不高。为了解决靶场在数据管理方面所面临的诸多问题,靶场报靶系统应运而生,为靶场的数据提供从前端到后端一体化的管理。靶场报靶系统主要包含前端打靶信息采集分析的报靶终端、数据汇聚与转发的网关系统以及后端管理存储的服务器平台。网关系统作为靶场报靶系统的重要组成部分,完成了报靶终端与服务器平台之间的数据交换,该设备具有传输带宽大、传输稳定性高与安全性好等优点。本文研究开发了基于PowerPC处理器的报靶数据网关硬件系统。该系统以PowerPC处理器MPC8569E为核心,配备大容量DDR3 SDRAM为系统程序的执行提供内部存储资源,扩展I2C、RS232等接口实现交互与控制,通过百兆以太网光接口接收前端报靶终端采集上传的数据,并对数据进行整理加密,再经由千兆以太网接口将数据交给服务器平台进行管理存储,实现数据交换,同时通过RS422接口进行设备管理。系统的千兆以太网接口进行了冗余设计,保证工作的可靠性,使用光通道传输使得系统能够支持更高带宽、更远传输距离,同时拥有更低的损耗以及更强的抗干扰能力。测试表明,本文所研究开发的网关系统在实验室环境下能够接收报靶终端的数据并进行转发,数据传输稳定准确,满足了设计要求。
[Abstract]:With the popularization of shooting, all kinds of shooting ranges are developing continuously. The traditional method of data management is not only inefficient, but also low in accuracy and reliability. In order to solve the problems of data management in range, the target reporting system emerges as the times require, which provides the integrated management from the front end to the back end for the range data. The target reporting system of range mainly includes the target terminal for collecting and analyzing the front-end target information, the gateway system for data gathering and forwarding, and the server platform for back-end management and storage. As an important part of the target reporting system, the gateway system has completed the data exchange between the target terminal and the server platform. The device has the advantages of large transmission bandwidth, high transmission stability and good security. In this paper, the hardware system of target data gateway based on PowerPC processor is developed. The system takes PowerPC processor MPC8569E as the core, equipped with a large capacity DDR3 SDRAM to provide internal storage resources for the execution of system programs, extends the interfaces such as I2CU RS232 to realize interaction and control, and collects the uploaded data through a 100-megabit Ethernet optical interface to receive the data uploaded from the front-end target terminal. The data is arranged and encrypted, and the data is managed and stored by the server platform through the Gigabit Ethernet interface, and the data exchange is realized. At the same time, the device management is carried out through the RS422 interface. The Gigabit Ethernet interface of the system is designed by redundancy to ensure the reliability of the operation. The optical channel transmission enables the system to support higher bandwidth, longer transmission distance, lower loss and stronger anti-jamming capability. The test results show that the gateway system developed in this paper can receive and forward the data of the target terminal in the laboratory environment, and the data transmission is stable and accurate, which meets the design requirements.
