[Abstract]:The research topic of this paper comes from the horizontal project "time synchronization instrument" equipment development. As one of the core modules of the time synchronization instrument system, the control unit realizes the functions of man-machine interaction, message processing, remote control and so on. This paper takes the design and realization of the control unit of the time synchronization instrument as the starting point, according to the function characteristic of the control unit. Based on the external communication interface of S3C2440A, the connection between S3C2440A and peripheral equipment data port and control port is designed. Including the FPGA chip LCD display, Ethernet MAC controller, as well as the RS232 serial port connection, write the corresponding driver. The parameter setting and remote control of the system are completed. The man-machine interactive control interface is realized by using keyboard, LED lamp and LCD display screen. The message processing is realized by Ethernet controller and the CRC check method is used to check the message in the process of processing to ensure the safety and reliability of the message processing. The remote control is realized by Telnet. The software design of the control unit of the time synchronization instrument is based on Linux operating system. The software program mainly realizes the recompilation and transplantation of the operating system kernel, the construction of the platform, the display of LCD, and the keyboard control. Operation menu control LED indicator lamp control, parameter setting, message processing, remote control and other functions. In the program implementation process, designed a reasonable software operation flow, making the time synchronization instrument easy to operate. Run smoothly. Through the function test of the time synchronization instrument control system, it is verified that the work of this paper has realized all kinds of functions required by the time synchronization instrument, and the research results and the solutions to the key problems are also given. It has certain reference value for the design of similar engineering application.
