“…In this paper, a power system transient signal data acquisition system with GPSbased synchronization is developed to satisfy the high-speed transient signal synchronized data acquisition requirements. Because FPGA has the advantage of high speed, high efficiency, small delay, all completed by the hardware logic, it is widely used in high-speed data acquisition system [7][8][9]. The system demonstrated in Fig 2 implements FPGA to achieve high-speed synchronized data acquisition, DSP (TMS320C6713) to realize transient signal recording and calculation related terms, and ARM (S3C2440) to achieve the function of transient data storage and system management.…”

This paper presents the methods for power system transient signal data acquisition, it includes two key technologies, the first is high-precision GPS-based remote synchronization for data acquisition, and the second is high-speed sampling and storage technologies. For the first problem, a single variable linear regression model is established for the GPS PPS signal and a UCT on-line estimation algorithm is developed to generate accurate and steady PPS (pulse per second). The sampling pulse which is synchronized with the corrected second pulse is generated simultaneously. For the second problem, a high-speed data acquisition system with a two level circulating storage scheme specialized for transient signal recording is developed in this paper.

“…The first is the sequence and timing unit, which generates all digital control signals for the CCD camera, such as the transfer pulse for TH7899, and the readout clock of the ADC and DAC. The second is a necessary peripheral circuit, which supplies a 4K FIFO memory for an image readout buffer and 16M SDRAM for the image memory with 16 bits width [6,7].…”

The Space Solar Telescope (SST) is the first Chinese space astronomy mission. This paper introduces the design of a high-performance 2K × 2K charge coupled device (CCD) camera that is an important payload in the Space Solar Telescope. The camera is composed of an analogue system and a digital embedded system. The analogue system is first discussed in detail, including the power and bias voltage supply circuit, power protection unit, CCD clock driver circuit, 16 bit A/D converter and low-noise amplifier circuit. The digital embedded system integrated with an NIOS II soft-core processor serves as the control and data acquisition system of the camera. In addition, research on evaluation methods for CCDs was carried out to evaluate the performance of the TH7899 CCD camera in relation to the requirements of the SST project. We present the evaluation results, including readout noise, linearity, quantum efficiency, dark current, full-well capacity, charge transfer efficiency and gain. The results show that this high-performance CCD camera can satisfy the specifications of the SST project.

“…The filter coefficients: h(0)=h (27) The theoretical framework of this acquisition card shows in the Fig.5, which is mainly composed by FPGA [8], PC/104, Schmidt trigger and the configuration ways to FPGA and so on. The output signals of laser gyroscope and accelerator are the digital pulse, but their output signals have flash burr with high-low rim.…”

The measurements of dither offset frequency is used to reduce the impact of latching error for laser gyro. The method of linear phase low-pass filter is used to eliminate the dither impact and high-frequency measurement noise. Distributed arithmetic algorithm is used for the FIR filter, distributed arithmetic algorithm can complete a number of multiply operations efficiently by converting the multiply operation into the look-up table structure. The main functional circuits such as counters, digital signal processing algorithms are completed in FPGA, data acquisition circuit is designed with FPGA. PC/104 system is used as control module, whose driver is under DOS system. The data displays by interrupt. The experiments show that this acquisition card counts real-time and precise numbers. Taking PC/104 system simplifies the device complicacy.I.
