Embodiment Construction

[0040] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0041]The acquisition module is the interface between primary equipment and secondary equipment, emphasizing the integration of primary and secondary equipment. It is mainly responsible for collecting real-time information parameters of power equipment such as units, circuit breakers, transformers, and electrical loads, and communicating with the equipment management through network interfaces. Interact; it is also the executive device for the power system to control the power equipment.

[0042] The present invention is based on the data acquisition requirements of ship power station monitoring system, auxiliary equipment informatization and other equipment, and develops a type of AC analog (mainly including voltage, current, etc.), switch value acquisition and wave recording, and switch value output. Collect standard modules. M...

Abstract

The invention discloses a power station special acquisition module with a waveform recording function, which is characterized in that voltage, current and switching value signals are acquired in real time, alternating current analog quantity, direct current analog quantity and switching state quantity signals are locally converted into digital signals, sampling frames at the same moment are formed and are forwarded to upper layer software, and the upper layer software is used for recording the waveform. Effective value calculation, fault recording criterion starting and transient and steady state recording are carried out according to channel types. The invention relates to a small acquisition standard module for acquiring and recording alternating-current analog quantity (mainly including voltage, current and the like) and switching value and outputting switching value, which is developed on the basis of data acquisition requirements of equipment such as a ship power station monitoring system, auxiliary machine informatization and the like. Key technologies such as data real-time forwarding and data recording and storage are broken through, so that the requirement of specified data traceability is met.

Description

technical field [0001] The invention relates to a special acquisition module for a power station with a waveform recording function, and belongs to the technical field of wave recording and record design for marine power stations. Background technique [0002] With the continuous development of ship integrated power system technology and auxiliary equipment information technology, new requirements are put forward for the collection, processing and transmission of equipment on-site information. [0003] In terms of the integrated power system, the framework of the future intelligent integrated power system for ships will gradually evolve towards four levels, which are the acquisition execution layer, equipment management layer, station control management layer and comprehensive management layer from bottom to top. The control idea has gradually evolved into "distributed collection, layered fusion, hierarchical processing, and local control", and the operation status of the po...
