Abstract
The utility model relates to a power station failure diagnosis device with PLC design, which comprises a failure information detecting device, a failure database and a failure diagnosis hierarchical analysis device, wherein the failure information detecting device is connected with a power station system, and the failure database is respectively connected with the failure information detecting device and the failure hierarchical analysis system. The power station failure diagnosis device has the advantages that dynamic monitoring of the field data is provided, the running information of the power station is accurately gathered in time, various abnormality and failures can be diagnosed, and thus incipient failures can be prevented; the running state of the power station can be evaluated, and the reliability, the security and the effectiveness of the power station can be improved.
Description
Technical field
The utility model relates to a kind of trouble-shooter, particularly a kind of PLC design Accident Diagnosis of Power Plant device.
Background technology
Because the operation circuit in power station is comparatively complicated, components and parts are more, in case break down in the power station, search circuit bothers very much, brought a lot of inconvenient factors in maintenance and maintenance unmanned station for the user, there is the shortcoming of professional technique in the field maintemance personnel, the method of field maintemance does not form unified flow process, and field failure is bungled the chance of winning a battle because the limitation of region can not in time be handled rapidly.
Summary of the invention
The purpose of this utility model provides a kind of PLC design Accident Diagnosis of Power Plant device, PLC finishes power failure input, pre-service, conversion storage and passes through man-machine interface, provide localization of fault, report and the explanation fault diagnosis result, and provide the suggestion of fixing a breakdown accordingly for the operator.
The utility model is achieved like this, it comprises failure message pick-up unit, Mishap Database and fault diagnosis step analysis device, the failure message pick-up unit connects electric power station system, and Mishap Database connects failure message pick-up unit and fault diagnosis step analysis system respectively.The knowledge base of electric power station system fault is set up in the fault diagnosis step analysis, data by the scene are carried out deep reasoning from logic, find out failure cause, electric power station system the fault detecting point that might cause all introduce PLC, system can in time carry out fault handling, the essential information data in Mishap Database storage power station, real time data information and historical data information, the each event of failure of historgraphic data recording comprises (date time that fault type and fault take place, hour, minute, second), database information adopts the mode of cycle index, has write down last 50 times failure condition in actual the use, and these records are capsule information of system's operation, the handled easily personnel understand the power station situation, and it is overhauled and safeguards.
The utility model has the advantages that: the dynamic monitoring field data is provided, has gathered the power station operation information timely and accurately, and various unusual or faults are made diagnosis, the prevention incipient fault; The power station running status is made evaluation, improve power station reliability of operation, security and validity.
Description of drawings
Fig. 1 is a principle of work block scheme of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises failure message pick-up unit 2, Mishap Database 3 and fault diagnosis step analysis device 4, failure message pick-up unit 2 connects electric power station system 1, and Mishap Database 3 connects failure message pick-up unit 2 and fault diagnosis step analysis system 4 respectively.Barrier diagnosis step analysis is set up the knowledge base of electric power station system fault and is carried out deep reasoning from logic by the data at scene, find out failure cause, electric power station system the fault detecting point that might cause all introduce PLC, system can in time carry out fault handling, the essential information data in Mishap Database storage power station, real time data information and historical data information, the each event of failure of historgraphic data recording comprises (date time that fault type and fault take place, hour, minute, second), database information adopts the mode of cycle index, write down last 50 times failure condition in actual the use, these records are capsule information of system operation, and the handled easily personnel understand the power station situation, and it is overhauled and safeguards.
