Study of Power Consumption of Timepix3 Detector
摘要： The Timepix3 readout chip — the latest member of the Medipix family of hybrid pixel detectors — brought several new functionalities in comparison with the older Timepix, i.e. a high hit-rate, a time granularity of 1.5625 ns, a data-driven readout scheme (with a per pixel dead time of approximately 475 ns), and the capability of measuring Time-over-Threshold (ToT) and Time-of-Arrival (ToA) in each pixel at the same time. However, the high power consumption of the Timepix3 in the standard setting prevents its use in applications with limited power budget. Moreover, the high power consumption poses the risk of overheating the sensor so that proper cooling is crucial. The presented work investigates the effect of different settings in the analogue and a digital part of the Timepix3 detector on its power consumption. Measurements were performed with the Timepix3 chipboard. The firmware of the Katherine readout was modified so that the user can monitor the power consumptions of analogue and digital part “on-line” (directly in the control software). In standard settings, a power consumption of approximately 1.3 W was found. By changes of internal DACs, the consumption could be reduced to 650 mW. Further reduction was achieved by the change of the clock management in the digital part of the Timepix3. In result, a power consumption of 216 mA could be achieved. In these low power settings, the ToA clock was reduced to 10 MHz and thus the time binning was 100 ns. The energy resolution was not affected significantly. The pixel dead time is also negatively affected when the matrix clock is reduced. In the case of 10 MHz, the minimal per pixel dead time is 1.9 μs.

Development of the readout system for a time projection chamber prototype
摘要： A new GEM-TPC prototype with a laser calibration system is being designed to study the key issues of high-precision track detection whose aimed spatial resolution is better than 100 μm. Meanwhile, a readout system with scalability for the TPC is also being developed. Design of the readout system is based on the architecture of front-end ASICs and commercial ADCs for its advantages at high count rates. Given the requirement of several hundred channels, the system is composed of multiple front-end cards and DAQ boards. The DAQ boards are daisy-chained via bidirectional optical fibers, which transmit clock, trigger, data and control signals simultaneously. To achieve timing synchronization, the GigaBit Transceiver (GBT) firmware is employed to ensure fixed latency between the boards. This paper is focused on the design and setup of the DAQ system, including clock structure, trigger alignment, high-speed data acquisition, etc. The DAQ system consisting of 512 channels has been built, and tests have proved that the entire system works correctly and meets the expected requirements.

摘要： In this paper, the design and the development of a remote system for continuous monitoring of leakage currents and ground currents in high voltage electrical substations are proposed. Based on wireless local area network technology, the system can be used to monitor continuously a variety of plants within the substation and has low power consumption with inbuilt overvoltage protection. It consists of a transmitter module equipped with a data acquisition (DAQ) system connected to leakage current and voltage sensors, and a receiver module connected to a remote controller for data processing and storage. The principle of operation and the characteristics of the various components of the system are described. Validation tests have been used to verify its performance in three different test situations: A) laboratory monitoring of the leakage current and voltage of a distribution surge arrester; B) laboratory measurement of the leakage current of an outdoor insulator; and C) ?eld monitoring of the earth current and potential rise of high-voltage tower. The measured results are in close agreement with those recorded directly through a DAQ card with ?ber-optic and coaxial cable connected systems. Data processing is carried out at the receiving end so that the monitored parameter is displayed continuously or at speci?ed time intervals. The operation of the system has been tested and proved resilient under high-frequency interference signals such as those generated by corona and surface discharges.

摘要： A nominally circular 2-D broadband acoustic array of 1.3-m diameter, comprising 508 sensors and associated electronics, was designed, built, and tested for ambient noise imaging (ANI) potential in Singapore waters. The system, named Remotely Operated Mobile Ambient Noise Imaging System (ROMANIS), operates over 25–85 kHz, streaming real-time data at 1.6 Gb/s over a fiber optic link. By using sensors that are much larger than half-wavelength at the highest frequency of interest, so with some directionality, good beamforming performance is obtained with a small number of sensors compared to a conventional half-wavelength-spaced array. A data acquisition system consisting of eight single-board computers enables synchronous data collection from all 508 sensors. A dry-coupled neoprene cover is used to encapsulate the ceramic elements as an alternative to potting or oil filling, for easier maintenance. Beamforming is performed in real-time using parallel computing on a graphics processing unit (GPU). Experiments conducted in Singapore waters yielded images of underwater objects at much larger ranges and with better resolution than any previous ANI system. Although ROMANIS was designed for ANI, the array may be valuable in many other applications requiring a broadband underwater acoustic receiving array.

A multi-channel PCI express readout board for fast readout of large pixel detectors
摘要： Recently the ATLAS Pixel Detector at CERN has been upgraded by inserting an additional layer of pixels, the Insertable B-Layer (IBL). In addition, the off-detector readout electronics of the other layers that composed the Pixel Detector (the B-Layer, the Layer 1, the Layer 2 and the Disks) were updated using the IBL readout boards. The system has been updated, one layer at a time, giving priority to the next critical layer as the luminosity and level-1 trigger frequency increased. Hence, after IBL, the first critical layer was the Layer 2, then the Layer 1 and finally the B-Layer and the Disks. Eventually, after the technical stop in 2018 the entire ATLAS Pixel Detector will share the same off-detector readout electronics. In parallel with the commissioning of the upgrade of the current ATLAS Pixel Detector we have designed and fabricated a new readout electronic board to address the requirements of the LHC Phase-2 upgrade. Two batches of prototypes of a Peripheral Component Interconnect Express (PCIe) Gen. 2 boards have been designed and fabricated, the second being a patched version of the first. The first batch was composed of two boards, called Pixel ReadOut Driver (Pixel_ROD) and the second batch was made of five cards called ??-LUP. All the boards feature many of the input–output ports and interfaces to address the requirements of the future front-end electronics being developed for the Large Hadron Collider (LHC) Phase-2 upgrade. Thus, the current VERSABUS Module Eurocard (VME) bus will be replaced with the PCIe bus to accommodate the huge increase of throughput (data to be transferred to the DAQ). In this new scenario, the GigaBit Transceiver (GBT) and Aurora protocols are compatible with our boards and the GBTx and RD53A chips will be the first components to be interfaced with. Some laboratory results and measurements are presented here.

摘要： Use of solar PV cells to harness electricity has been more developed in recent years. Researchers are more focusing on to extract more power from available area. But more consideration should be given to the energy loss during power extraction. Because the energy loss means the wastage of available power .The one of the solutions to save energy loss is the power plant monitoring. This paper describes the design of remote data acquisition system for solar plant using internet of things. The solar power plant monitoring will provide the real time data for net power, net/total energy and irradiance. This data will be helpful to take decision to schedule operation & maintenance activities & preventive maintenance.

摘要： Decades of heavy investment in laboratory-based brain imaging and neuroscience have led to foundational insights into how humans sense, perceive, and interact with the external world. However, it is argued that fundamental differences between laboratory-based and naturalistic human behavior may exist. Thus, it remains unclear how well the current knowledge of human brain function translates into the highly dynamic real world. While some demonstrated successes in real-world neurotechnologies are observed, particularly in the area of brain-computer interaction technologies, innovations and developments to date are limited to a small science and technology community. We posit that advancements in real-world neuroimaging tools for use by a broad-based workforce will dramatically enhance neurotechnology applications that have the potential to radically alter human–system interactions across all aspects of everyday life. We discuss the efforts of a joint government-academic-industry team to take an integrative, interdisciplinary, and multi-aspect approach to translate current technologies into devices that are truly ?eldable across a range of environments. Results from initial work, described here, show promise for dramatic advances in the ?eld that will rapidly enhance our ability to assess brain activity in real-world scenarios.

摘要： Data collection and analysis of product are causing more and more attention with the rapid development of intelligent manufacturing. Faced with the problem that data acquisition system cannot be used universally, researchers have a long way to go. This paper designed a configurable data acquisition system for automatic filling lines, and the system can be used in other working lines without changing the hardware. The system is based on ARM and consists of three parts: data acquisition, server and cloud platform. Data acquisition part is responsible for acquiring data and sending data to host computer. Server part is used for receiving data from host computer and saving it in the database. Cloud platform serves for users and provides data analysis. The hardware design and software design of the acquisition board are also analyzed, meanwhile the communication protocol is made to ensure the data transmission. The data acquisition has been realized in this system and the whole process is running smoothly without problem.
