Wireless Programming In The Ctcs

Rail is an important pillar industry about the livelihood of the people and our country, in the development of rail transport, the transport safety is the topic that the people most concerned about. In order to ensure the China Railway which in rapid development be in the safe operation under the condition of high-speed and high-density, and also to develop the train control system of our own, the wireless programmer which is the key equipment in Chinese Train Control System is studied in this dissertation.The device can write and modify the data which in the Balise (the key equipment in modern high-speed train control system), and it has the function that checking programmed correctly or not .In addition, it can link to the Pocket PC or Notebook. The dissertation includes four technical issues.1, the wireless programmer using three different wireless channels to achieve the programming and checking data that storaged in the Balise;2, in order to ensure the safety of the message in the Balise, the programming circuit is not activated in normal operation and storage period;3, the programmer should have the functions that checking and reporting the error for the situation of the rewriting.4, the programmer can easily connect to the notebook computers.In the study of the dissertation, it will determine the wireless programmer system's basic architecture and workflow firstly by the functional requirements and the actual condition in use. And then select the chips of the various modules, design the hardware circuit and arrange the appropriate hardware interface. Finally, complete the relevant software designing.
