[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.
