Abstract
A kind of thermal power unit operation early warning and fault diagnosis system, by system-computed station (1); Data communication interface (2); Fielded system control station (3); Loop network (4); The unidirectional fire wall of network data (5); Fielded system network (8) and system client (6) composition.Fielded system control station (3) is by fielded system network 8 connection data communication interface (2); Data communication interface (2) abutment ring l network (4); Described system-computed station (1) abutment ring l network (4); Between described loop network (4) and intranet (7), interconnection network data sheet is to fire wall (5); System client () 6 connects intranet (7).On-the-spot real time data abundant in SIS system combines with Intelligent Fault Diagnosis Technique by the utility model, the situation of change of each signal of interest in real-time monitoring field, safeguards providing quick, easy method for thermal power plant's safe operation and commercial unit.
Description
Technical field
The utility model relates to a kind of thermal power unit operation early warning and fault diagnosis system, belongs to thermal power unit operation technical field.
Background technology
DCS control system in current most of thermal power plant, generally lacks fault detect and warning function, the warning function only had, and is also the warning after occurring accident.Such as at collecting and distributing alarm control system and the automatic protection alarm system of power plant's application.But the correct early warning of fault is even more important in reality, it can point out maintainer to check the equipment that may need to be serviced, and tells operations staff which operational outfit pays particular attention to.This just needs us to further investigate the mechanism of fault, understands the reason that fault occurs, correct record trouble sign, follow the tracks of failure symptom development trend, provide the method for correct diagnosis and management suggestion in time, thus avoid the generation of accident, accomplish the early warning before accident.
Summary of the invention
The purpose of this utility model is, lack the problem of fault detect and warning function according to the DCS control system of existing thermal power plant, the utility model discloses a kind of thermal power unit operation early warning and fault diagnosis system.
The technical solution of the utility model is, a kind of thermal power unit operation early warning and fault diagnosis system comprise system-computed station, data communication interface, fielded system control station, loop network, the unidirectional fire wall of network data, fielded system network and system client.Fielded system control station is by fielded system network connection data communication interface; Data communication interface abutment ring l network; System-computed station abutment ring l network; Between loop network and intranet, interconnection network data sheet is to fire wall; System client connects intranet.
Principle of work of the present utility model is, fielded system control station is connected with data communication interface, field data is transferred on SIS system loop network, the system-computed station be connected on loop network is read field data and carries out fault diagnosis, fault diagnosis result is transferred to system client by the unidirectional fire wall of network data, can browse fault diagnosis result at system client.
The beneficial effects of the utility model are, on-the-spot real time data abundant in SIS system combines with Intelligent Fault Diagnosis Technique by the utility model, the situation of change of each signal of interest in real-time monitoring field, fault pre-alarming is carried out when there are abnormal conditions, avoid generation and the extension of fault, and failure cause can be found in time when fault produces, provide handling suggestion.Operations staff can be helped according to this to process field failure in time, safeguard providing quick, easy method for thermal power plant's safe operation and commercial unit.Compensate for present stage various control system, comprise the deficiency of DCS in early warning and fault detect.
The utility model is applicable to thermal power plant's on-line operation fault diagnosis.
Accompanying drawing explanation
Fig. 1 is the utility model apparatus structure schematic diagram;
In figure, 1 is system-computed station; 2 is data communication interfaces; 3 is fielded system control stations; 4 is loop networks; 5 is the unidirectional fire walls of network data; 6 is system clients; 7 is intranets; 8 is fielded system networks.
Embodiment
Embodiment of the present utility model as shown in Figure 1.
A kind of thermal power unit operation early warning of the present embodiment and fault diagnosis system, by system-computed station 1; Data communication interface 2; Fielded system control station 3; Loop network 4; The unidirectional fire wall 5 of network data; Fielded system network 8 and system client 6 form.Fielded system control station 3 is by fielded system network 8 connection data communication interface 2; Data communication interface 2 abutment ring l network 4; Described system-computed station 1 abutment ring l network 4; Between described loop network 4 and intranet, interconnection network data sheet is to fire wall 5; System client 6 connects intranet.
In the present embodiment, fielded system control station 3 is connected with data communication interface 2 by fielded system network 8, field data is transferred on SIS system loop network 4, system-computed station 1 server be connected on loop network 4 reads field data and carries out fault diagnosis, fault diagnosis result is transferred to system client 6 by the unidirectional fire wall 5 of network data, can browse fault diagnosis result at system client 6.
