The present document covers the minimum characteristics considered necessary in order to make the best use of the available frequencies. It does not necessarily include all the characteristics that may be required by a user, nor does it necessarily represent the optimum performance achievable. Close Range Inductive Data Communication equipment covered within the present document are considered by definition short-range devices. The power limits for frequency bands will be found in the current version of CEPT/ERC/Recommendation 70-03 [2] (or national regulations). The present document applies to Close Range Inductive Data transmitters and receivers operating
BS EN 60880-2009核电站.对安全重要的仪器和控制系统.形成A类功能的基于计算机系统的软件问题
This International Standard provides requirements for the software of computer-based I&C systems of nuclear power plants performing functions of safety category A as defined by IEC 61226.According to the definition in IEC 61513, I&C systems of safety class 1 are basically intendedto support category A functions, but may also support functions of lower categories. Howeverthe system requirements are always determined by the functions of the highest category implemented.For software of I&C system performing only category B and C functions in NPP as defined by IEC 61226, requirements and guidance of IEC 62138 are applicable.This standard provides requirements for the purpose of achieving highly reliable software. Itaddresses each stage of software generation and documentation, including requirements specification, design, implementation, verification, validation and operation.The principles applied in developing these requirements include:– best available practices;– top-down design methods;– modularity;– verification of each phase;– clear documentation;– auditable documents;– validation testing.Additional guidance and information on how to comply with the requirements of the main part of this standard is given in Annexes A to I.
BS EN 62270-2004水力发电站自动化.计算机控制用指南
This standard sets down guidelines for the application, design concepts, and implementation of computer-based control systems for hydroelectric plant automation. It addresses functional capabilities, performance requirements, interface requirements, hardware considerations, and operator training. It includes recommendations for system testing and acceptance. Finally, case studies of actual computer-based automatic control applications are presented.\nThe automation of control and data logging functions has relieved the plant operator of these tasks, allowing the operator more time to concentrate on other duties. In many cases, the plant's operating costs can be significantly reduced by automation (primarily via staff reduction) while still maintaining a high level of unit control reliability.\nAutomatic control systems for hydroelectric units based on electromechanical relay logic have been in general use for a number of years and, in fact, were considered standard practice for the industry. Within the last decade, microprocessor-based controllers have become available that are suitable for operation in a power plant environment. These computer-based systems have been applied for data logging, alarm monitoring, and unit and plant control. Advantages of computer-based control include use of graphical user interfaces, the incorporation of sequence of events and trending into the control system, the incorporation of artificial intelligence and expert system capabilities, and reduced plant life cycle cost.
