Research On The ZPW-2000A Monitoring System Based On ARM9 & The Integration Acquisition

ZPW-2000A is the automatic block instrument used in high-speed railway system. It sends different continuous-phase FSK signals. The signal represents the status of track occupation. The signal is received by receiving box, and processed by attenuating box. Then it is sends to the next section of railway. The monitoring system based on microcomputer monitors the signaling devices. The Integration Acquition is in charge of monitoring the power supply situation, cable isolation, current leaking and the blowout.This thesis is mainly about two parts. In the fist part, The testing system's hardware and software are designed. The testing system is used to test automatic blocks signaling device ZPW-2000A's signal. The testing system uses ZFFT arithmetic and use embedded system. The CPU is ARM9 series chips, the S3C2410A. The system makes full use of the ARM9 processor's recouses in the hardware designing. The system provides kinds of communication buses. The program is designed in a simple and efficient structure which is suitable for embedded system to process in the software programing.In the second part, the testing software is programed according to the principle of the integration acquisition testing tasks. The integration acquisition of the monitoring system based on micro computer is presented. The acquisition used LPC2292 chip as its processor. The finished system improved the processing capability, which makes it convenient to add new testing task meanwhile the system maintains the former tasks. This finished system is used in real rail-station CHAWU to test whether it works well.As a conclusion, to both parts, the problems during the development are presented in details. The thoughts and plans which can solve the problems and enhance the performance of system are described.
