In the test system, all kinds of signals need to be processed. In order to meet the need of test system,we propose a kind of method of overall design of the real-time monitoring and storage of analog signal and digital signal. And we descript that how the data is sent to PC to real-time monitor and how we read out the data of the storage, and at the same time, the effect of the real-time monitoring is mentioned. After the application of the practice, the stability and the reliability of the collection system get confirmed.
Data Acquisition System Based-on TMS320F2812 can quickly and easily for analog-digital converting, arbitrarily switching to 16 analog input channels. Serial Communication interfaces Make the system easy to use .The system is in design modular, can flexible debugging and modify.
This paper presents an automatic test system which can output one 2Mbit / S PCM signals and one 10.2Mbit / S PCM signals for the device testing; the system wih self-test function could calibrate the output two PCM signals; when the equipment is in the state of testing, you can real-time monitor the status of the device through the PC
In order to meet the needs of telemetry test system parameters testing, we propose FPGA based on telemetry data acquisition system's overall design, and describe the methods and processes of the collection of analog signal and the reception of digital signal in detail. According to the sampling rate of the slow-changing and the rapid-changing, the frame structure is designed. Under the control of PC, data collection and coding are achived by FPGA, and real-time monitoring of data is achived through testing platform and data storage is achived by data recorders to monitor and implement, and modelsim software simulates the timing of the program. After the application of the practice, the stability and reliability of the collection system get confirmed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
