The demodulation circuit is a major part of DC current comparator (DCC), of which performance directly influences the accuracy, sensitivity and noise of whole system. Separately describe the working principle of two demodulation methods, based on which the corresponding circuits were designed; experiments and simulation studies were carried out. The research results show that both methods can realize the function of converting the even harmonic signals characterizing the measured DC current to the corresponding DC voltage. The important advantage of peak difference demodulation is that it can demodulate all even harmonic signals. A high detection gain will be obtained accordingly, which is favorable to increase sensitivity. But the ripple of secondary current is large. Narrow band characteristics of phase sensitive demodulation are beneficial for reducing the system noise level; the ripple of secondary current is very small. As only second harmonic is demodulated, it is necessary to satisfy the best condition to achieve high sensitivity.

The complex electromagnetic environment today places a greater demand on the bandwidth and dynamic range of electronic measuring devices. In the case where the dynamic range of a high-speed ADC is limited, the same signal is amplified with different gains through multiple channels, and the signal is sampled synchronously by multiple ADCs, and then, the undistorted data frames with the largest magnification factor are selected by frame from multiple sampled data for restoration and merging (reconstruction) to improve the dynamic range of the signal acquisition and the real-time performance of sampling. In this paper, the working principle and key technologies of an analog channel for a broadband high-dynamic acquisition system are described in detail, and the relevant design indicators are tested and verified. The results show that the analog channel finally achieves the technical indicators including 300MHz bandwidth and 90dB input dynamic range.

Fault prediction plays a significant role in enhancing the safety, reliability, and stability of distribution network. However, the problem of enormous time-series data and discrete data makes the prediction great challenge. The imbalance between normal and fault samples will reduce the accuracy of the model. In addition, the influence of time-series variables on distribution network is direct and continuous, so the time-series feature extraction is the key technique for fault prediction. In this work, we propose a fault prediction method for distribution network based on CNN and LightGBM algorithm. This method deeply learns feature of time-series data by utilizing CNN, and improves the adaptability for imbalanced dataset by training LightGBM submodels. Experimental results based on fault dataset of a district in Chongqing from 2017 to 2018 show that fault prediction performance can be ameliorated by utilizing this method.

Isolated handheld oscilloscope is an indispensable measuring tool in the measurement. It has the characteristics of portability, flexible utilization and high safety performance. Conventional handheld oscilloscopes isolate the analog channels through transformers or optocouplers, but the bandwidth of oscilloscopes is limited due to the bandwidth limitations of the transformers and the drifting characteristics of the optocouplers. This paper presents a new isolation scheme through digital channels. Because the digital isolation chips can transmit at large rate and perform multiple channels in parallel, the transmission rate can theoretically unlimited grow. The bandwidth of the oscilloscope is only related to the analog channel. By means of digital channel isolation, the bandwidth of the isolated oscilloscope is not affected by the isolation channel, and reaches the maximum bandwidth of the traditional non-isolated oscilloscope. At present, the isolated oscilloscope by analog channels on the market has bandwidth of 200 MHz.However,the bandwidth of the non-isolated oscilloscope has reached 500 MHz or even 1 GHz. Based on this scheme, a dual-channel isolated handheld oscilloscope is designed with single channel sampling rate 2GSa/s and 300MHz bandwidth. The isolation between oscilloscope channels security level can reach CAT II 1000V, CAT III 600V. Its bandwidth is larger than the handheld oscilloscope on the analog channel isolation in the markets.

Scientific satellites can effectively detect astronomy. Accurate ground calibration experiments are required on the detector before the satellite payload is completed. Through the X-ray energy spectrum detected by the high-purity germanium detector, the energy resolution and energy response of the energy spectrum can be studied to meet the ground calibration requirements of the gravitational wave electromagnetic counterpart all-weather monitor (GECAM satellite). This paper mainly introduces the performance study of the X-ray high-energy part of the GRD detector, and conducts preliminary calibration experiments on the energy range from 80Kev to 150Kev. The test results: the high-purity enthalpy of the standard detector and the GRD detector have good energy linearity; The energy resolution of the single-energy X-ray of the GRD detector is better than 10.2%@79.9keV, which has good monochromaticity.

Ground-wave and cycle identification is significant technology of Loran-C signal processing. Due to fast attenuation of the Loran-C signal in inland areas and small difference between sky-wave delay and ground-wave delay, ground-wave and cycle identification cannot be carried out well by the methods of general optimized envelope correlation and peak detection. To address this problem, a method based on Multipath Estimation Delay Lock Loop (MEDLL) is proposed to perform ground-wave and cycle identification for Loran-C signal. The algorithm computes measured correlation function by optimal Loran-C envelope and extracts estimated delay value of ground-wave by MEDLL. Moreover, all the pulse signals in two complementary cycles (16 in total) are used to obtain 16 cycle identification results, respectively, and the result with highest confidence is selected as final identification output. Results demonstrate that the proposed method identifies the ground-wave and cycle of Loran-C signal accurately when sky-wave delay is 30$mu$s more than ground-wave delay, which meet the performance requirements of Loran-C receiver in wide inland areas. The method is robust to environmental noise and sky-wave interference.

Unmanned Aerial Vehicle (UAV) is widely used in daily life, commercial and military applications, because it is flexible and cheap. But the news of UAV accidents calls people to focus on Prognostics and Health Management (PHM) for UAV, which can predict and detect faults during the UAV ’s flight through the telemetry data. PHM can also help UAV adjust itself to avoid crashes. However, the existing PHM models on UAV have some common problems. The most outstanding one is that they are all suffering from lacking fault data. The amount of fault data is difficult to support PHM modeling. Therefore, establishing a fault injection platform will help in generating fault data and improving the performance of PHM methods. In this work, we propose a platform of fault injection based on ArduPilot. It can simulate different kinds of sensor and actuator faults which may happen on UAV during flight. Through the ground station, we can obtain the telemetry data with faults which can set up a database for PHM modeling. The experiment results show that this method has a good performance for fault injection.

-There will be great number of settleable residues during shooting of firearms. In traditional smoke chamber-detection, taking smoke chambers before and after shooting as the data test environment may affect the detection result. Considering this, we propose to measure data in a smoke-free environment created by automatically discharging smoke in detection system after analyzing the impact of settable residues on detection results, which may effectively avoid such impact. Results of detection of transmittance of muzzle smokes of 5.8mm and 7.62mm ordinary guns indicate that average efficiency of transmittance of improved detection method is improved by 3.04% and 3.09%, standard deviation decreased by 0.0117 and 0.0079 respectively compared with traditional detection method, with improved reliability, reduced detection time and significantly enhanced detection efficiency.
