The Design And Implementation Of Airport Snow Sweeper Communication Control System

As the science and technology developing fast, the combination of the communication technology, the computer technology and the embedded technology are not only the main trend in nowadays, but also are developing and expanding greatly in many fields such as the industrial control, medical, electronic communication, navigation, aerospace and so on. The design scheme of the snow sweeper communication control system is widely proposed and implemented in this article. It not only fills the snow sweeper communication links gap in domestic, but also considerables value at improving the level of the flight guarantee service of the airport.Based on the short distance wireless communication theory, with AT91SAM7S64 being the central control unit, the design of the software and hardware are implemented in this article. The data flow decoded, the error control coding and the working mode control of the snow sweeper's communication protocol can be implemented through the embedded software program. This subject comes from the project developed by Dalian Maritime University and Dalian International Airport. It mainly introduces the domestic and abroad status at present, the significance and contents of this subject. Meanwhile, it studies the embedded OS and the wireless transmission technology including the wireless networking technology, the transplantation of OS, the error control, the serial communication technology and so on. It also makes some discussion about the wireless networking communication protocol.The paper mainly finishes the work as follows:(1) According to the status of the domestic and abroad snow removing at present, based on the advanced wireless data transmission technology, with the embedded technology as the core, the hardware platform of the snow sweeper's communication network is built.(2) Studying on the wireless communication protocol, using the embedded software programming technology, the wireless communication protocol is applied into operation and all functions of the snow sweepers' communication network are implemented.(3) The transplantation ofμC/OS-ⅡOS, the transplantation of the kernel is reconfigured, so it can meet the requirement of this system. The design of the peripherals driver (the ports between OS and access devices). It can provide OS with hardware accessing functions by programming hardware read-write control functions.This system technology is advanced, stable running and practical. With plenty of simulation and field tests, it meets the requirements of the functions and applies patent, it is used by Dalian International Airport. It not only gaines good results, takes the leading position in domestic, but also has widely development prospects.
