Abstract
In order to improve the problems the telesignaling transmission distance is short,transmission rate is a single in traditional telemetry system. A receiving system is designed based on the PCM long-term high speed multi-rate. This receiving system uses FPGA programmable logic devices as PCM Telemetry Demodulator. Under the control of its internal logic,it achieves decoding to PCM signal. Demodulated data are transfered to the computer through the PCI bus for analyzing and drawing;or recorded in storage for data recovery and back to read. It can realize serial data transmission via 60 m shielded twisted-pair cable,limit distance is 200 m,the received signals are two different bit rates of PCM data. After testing the relevant parameters,the results show that the system can transmit stability,accurate receive data,it has anti-jamming ability,and obtains the desired goals.关键词
