Hardware Design Of Railway Simulation Lab And Signal Program Test

With the rapid development of China's railway, a variety of new technology, new equipments are put into use successively. Constructing dynamic simulation sand table can reflect modern urban rail transit directly. Establish the modern urban rail transit railway comprehensive laboratory which integrating the railway transportation operational management and signal control technology is imperative. Railway signal simulation laboratory is a control integration laboratory hardware platform with its control object based on sand table models .This platform provides the simulation laboratory a necessary simulation environment.By analysis the control integration laboratory's function in detail and combining the signal and its control technology's situation at present, the article designs some hardwares aiming at railway signal simulation laboratory. These hardwares are signal data acquisition and control card, signal integration control card, rail control card, locomotive control card and other related hardwares.The article also offers the test procedure to test railway signal.This thesis comprises several sections as follows: 1.Railway signal simulation lab function requirement analysis, list the research contents and realization method in need; 2.Design the railway signal equipment's data acquisition and control card, including the function distribution of the MCU's IO port, the interface with transportation management system, the wireless interface with locomotive communication, and the LIN bus interface with railway signal simulation equipment communication; 3.Design railway signal simulation equipment, including signal integration design, hardware design of electromagnetic rail and hardware design of wireless simulation locomotive; 4. Analyze the software's modules and functions of the entire system, analyze and design the LIN bus agreement in detail. Compiled the data acquisition and control card of the railway signal equipment and compiled integration signal test procedures.The ultimate test results can control the state, brightness and flashing of the signal light flexibly, verify the correctness of the hardware design and achieved the design purpose.
