A standard PCIE interface is connected to a standard PCIE interface of a main board of an interface machine equipment of a power plant; data are written into a cache access chip through the standard PCIE interface, then a high-speed logic processing chip calls a data discrimination algorithm stored in a memory chip for discriminating and pre-processing the data, and data after the processing are connected with application equipment of the power plant through a first optical fiber interface or a second optical fiber interface. The physic card can program and configure flexibly, is easy in modification and system upgrading, achieves very good reliability and stability, can realize real-time, concurrent and large-data-volume discrimination and pre-processing, achieves 100% efficiency of acquiring and forwarding data, avoids influence from environment factors, can run continuously for a long time, can avoid losing data packet and the like.
Description
Technical field
The present invention relates to a kind of data screens and pre-service physical card.
Background technology
Along with the arrival of large data age, all trades and professions are all faced with the processing of mass data and information.For fuel-burning power plant, the work under bad environment of thermal measurement instrument, noise, high temperature, pressure wave, electromagnetic wave, mechanical vibration etc. are disturbed frequent, and the reliability and stability of production data decline thereupon in real time, and easily there is catastrophic failure in measuring point.So more and more measurement data alignment techniques that adopt, reject and reconstruct the appreciable error of real-time production data in Fossil-fired Unit Performance monitoring system.
On-the-spot data pre-service be towards at a high speed, the real-time processing of high volume data stream, its feature all has absolute time restriction processing stage of being input, processing and the output of system etc., and real-time has been proposed to very high requirement.Therefore, it is enough fast that the speed of processing unit is wanted, to meet the real-time restriction of operation.
Existing measurement data alignment technique system data transfer efficiency is poor, inadequate to support concurrent, big data quantity, does not fully excavate the potential of computer hardware, existing system is transformed to the dirigibility that lacks expansion, and cost is higher.
Summary of the invention
The object of the present invention is to provide that a kind of professional performance is high, the data of logistic discrimination algorithm at a high speed and extensibility screen and pre-service physical card, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of data are screened and pre-service physical card, comprise Standard PC IE interface, high speed logic process chip, the first optical fiber interface, the second optical fiber interface, communication connects pilot lamp, alarm lamp, memory chip and buffer memory access chip, described Standard PC IE interface is connected with the Standard PC IE interface on power plant interface message processor (IMP) equipment mainboard, data write in buffer memory access chip by Standard PC IE interface, then by the data of storing in high speed logic process chip invoke memory chip, screen algorithm and carry out examination and the pre-service of data, the data of finishing dealing with are connected with power plant application apparatus by the first optical fiber interface or the second optical fiber interface.
As the further scheme of the present invention: be also provided with communication on described physical card and connect pilot lamp and alarm lamp, the demonstration situation that connects pilot lamp and alarm lamp by communication judges the groundwork situation of physical card.
As the further scheme of the present invention: described data are screened algorithm and adopted the data checking method that improves 53H algorithm.
Compared with prior art, the invention has the beneficial effects as follows:
1) on design aspect, adopt the high speed logic process chip based on FPGA, mainboard is technical grade panel, and peripheral interface provides 2 of high speed fibre transmission interfaces, adopts the power supply of PCIE expansion interface and the data acquisition of standard, meets the requirement of PC mainboard interface.
2) data are screened and with the support of pre-service physical card, the simulating signal of control system are converted to corresponding the parsing and processing of digital signal process of calculating function identification, show that required data retransmission is to application system.
3) this physical card can flexible programming and configuration, is easy to revise and system upgrade, possesses good reliability and stability.
4) design philosophy of this programme and principle be reliability and security, real-time and high efficiency, integration, compatibility, maturity and advance, standard form and opening, extendability and can management type, the principle such as extensibility.
5) data are screened with pre-service physical card and can be accomplished efficient examination and pre-service real-time, concurrent, big data quantity, gather and the efficiency of forwarding data reaches 100%, be not subject to environmental factor the long-term continual operation of impact energy, do not lose the performance index such as packet.
6) mainstream data examination algorithm and self-defining data are screened check algorithm to the support of this physical card both at home and abroad at present, as modified 53H data detection method, compare with traditional 53H method, increased feature quantity sequence check, make the assay of 53H method more reliable, improve checkability and check reliability, actual operation is stronger.Newly-increased 2 smoothing methods of head and the tail are to the supplementing of traditional 53H method, and have realized for each sudden change of 4 check of sequence head and the tail, and have followed the tracks of well after sequence or front variation tendency.Introduce uncertainty as the deviation ratio of smooth value and original value compared with limit value, avoided randomness that experience chooses, without the triviality of basis and deterministic process, check is set more theoretical foundation, and the data that can well coordinate the performance of hardware to reach real-time high-efficiency are screened and pre-service.
