On the basis of the characteristics of the shock pulse GPR echo signal and by using the principle of clock distribution control parallel data acquisition, we realize the high-speed data acquisition with low-speed parallel ADC device. The system consists of part of the signal input module, signal conditioning module, clock distribution module, data acquisition module and FPGA control module. The design with Simple circuit, level of clarity and good stability. It has practical significance and provides some reference to designers of other high-speed A/D conversion.

To resolve the problem of acquiring multi sensors signals synchronously in a distributed system, a project of distributed synchronous data acquisition based network time server was designed. The system comprised multi distributed sensor units, a centralized control unit and D&C (display and control) center. Each sensor unit was equipped with a data acquisition module. All data from sensor units were concentrated and sent to the D&C center, and the D&C center implemented power supply and management of sensor units via the centralized control unit. To synchronize the data acquisition modules, a network time server was employed in the D&C center. It received standard time information from GPS and outputted the time signal with DCF77-encoding. Each data acquisition module received and decoded DCF77 time signal, obtaining absolute time and synchronizing its time base. Above project was applied successfully in a system comprising 20 distributed sensor units. The results prove the designs feasible.

Traceability has an enormous value for companies, but especially for those working in the regulated environment. It plays a special role in the field of pharmacy with respect to manufacturing, controlling and distributing batches of drugs. Through the guidance of Good Manufacturing Practice (GMP) traceability should be ensured. An increasing number of pharmaceutical companies are member of one of the global pharmacopoeias (United States Pharmacopeia, European Pharmacopeia and Japanese Pharmacopeia). The specifications of these pharmacopoeias describe the best practice in documentation, control, qualification and risk management. But however, the pharmacopoeias are written very generally and do not distinguish between the vendors of the analytical instruments. Here, we analyze how chromatographic analyses and data acquisition rely on a specific vendor of the device and the chromatography data system (CDS), the controlling software. We present a way to compare the data acquisition of different CDSs communicating with HPLC instruments. A newly developed software called Data Collector allows the acquisition of data from a HPLC detector parallel to the controlling CDS in the same run. Two HPLC systems and two different CDSs using a well defined sample standard have been tested. The direct comparison of the acquired data precludes unexpected data manipulations of both tested CDSs and shows that there are primarily deviations between the CDSs due to time variations only which depend on the sampling rate. All in all the Data Collector can be used for the traceability of data acquisition.

Microcomputer Protection

Current microcomputer protection experimental system is created based on LabVIEW. Each module was created based on the modular thinking (data acquisition module, start module, algorithm module). Functions of microcomputer protection were implemented. Fault data was generated by fault simulation software MATLAB. LabVIEW controls and loop structure achieved simulating a variety of action logical relationship of computer protection. This system had many advantages, such as visibility, controllability, authenticity and flexibility. The system was able to verify the performance of computer protection at different fault. The system was also able to analyze the situation of computer protection maloperation and misoperation, thus it further provided teaching platform for the three section current microcomputer protection experiment.
