Hardware Design Of Reporting Target's Data Gateway System Based On PowerPC Processor

With the popularity of shooting sports,all kinds of shooting range continue to develop.The traditional method of data management is not only inefficient,but also has low data accuracy and reliability.Shooting range intelligence target system came into being to solve many problems the shooting range faces in data management and provide intelligent management for the shooting range.Shooting range intelligence target system mainly includes the intelligent report target terminal,gateway system and server platform.As the important part of the intelligent target system,the gateway system implements the data exchange between the target terminal and the server platform.The Gateway system has a wide range of transmission bandwidth,high transmission stability and security,and so a series of characteristics.This thesis designs hardware of intelligent report target's data gateway based on PowerPC processor.The system uses the PowerPC processor MPC8569E as the core.It is equipped with high-capacity DDR3 SDRAM to store data and extend the interfaces such as I2C and RS232 to implement interaction and control.Data collected by targets is received through the 100M Ethernet optical interface.The data is collated and encrypted,and then sent to the server through the Gigabit Ethernet interface.Equipment management is implemented through RS422.The system is redundant designed,to ensure the stability of the work.The optical channel transmission allows the system to support higher bandwidth and longer transmission distance while having lower loss and stronger anti-interference ability.The test shows that the gateway system can receive and transmit the data of target terminals in the laboratory environment.The data transmission is stable and accurate,which meets the requirements.
