Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The DAS (Diversity Actuation system, diversity drive system) in the nuclear power plant is used as a backup system for the common cause faults of the software of the RPS (Reactor Protection system ), and the requirement and the RPS must adopt diversity configuration to minimize the probability of the common cause faults of the DAS and the RPS. At present, when DAS and RPS are configured in diversity, three diversity strategies exist at present, specifically:
strategy a: different basic technologies (e.g., analog and digital).
Policy B: different methods (such as FPGA method and CPU method) under the same basic technology.
Policy C: different architectures (e.g., different microprocessor architectures) under the same technology approach.
At present, the diversity strategy commonly used is that the DAS adopts an analog technology and the RPS adopts a digital technology, so that the condition that the same technology simultaneously fails is avoided.
When the DAS is in operation, in order to monitor the reliability of the DAS operation, data monitoring operation is needed to be carried out on the DAS so as to timely process the fault when the DAS is in fault and avoid affecting the fault shutdown of the DAS. How to implement the data monitoring operation of the DAS is a technical problem that needs to be solved by those skilled in the art.
To implement the data monitoring operation, a DAS as shown in fig. 1 may be employed.
In fig. 1, the architecture is divided into two layers, an Analog processing layer (Analog part) and a LOGIC processing layer (LOGIC part), wherein:
analog quantity processing layer: the threshold comparison processing of the analog quantity and the distribution function of the threshold comparison result are realized, and the threshold comparison result is displayed through the indicator lamp.
Taking SG2 Low Flow signal as an example, after being collected by the IM module, the signal is sent to the XU module, converted into a switching value signal by the XU module, and then distributed into two paths of signals by the XE module, and sent to two three-out two (2 out of 3) signals in the Logic part respectively.
Logic processing layer: the processing of the three-out-two And logic And the like conforming to the logic is realized, and the processing result is displayed through an indicator lamp And output through a hard wire (Wired logic).
In practical applications, the key parameter indication may be displayed by an indicator light or meter through fig. 1. In this way, due to the limited cabinet or tray space, the number of indicator lights or meters allowed to be placed is limited, resulting in a limited number of key parameter monitoring variables, which can only be selected for monitoring, and which cannot monitor the full range of variables. In addition, when data monitoring is performed, the on-off output result can be observed only by the on-site indicator lamp, the numerical value of the analog quantity cannot be monitored, and the type of the monitored variable is single.
In addition, the system has no history record, is inconvenient for problem location, if key variable record is needed, the variables are required to be sent to a third party system for monitoring through hard wiring, the number of external wiring is increased, the number of hard wiring is limited by the IO (Input/Output) scale and the wire inlet space of a cabinet, the data quantity which can be sent to the third party is limited, the number of variables with history records is further limited, and when problems occur, the problems are required to be checked by combining the history data, particularly the problems are caused by flashing, and if the history data is limited, the states of all signals when the history data are analyzed cannot be analyzed, so that the analysis of the reasons of the problems is very difficult.
In order to solve the problems of small quantity and single type of monitoring variables, the invention adopts the VDU (Visual Display Unit, graphic display unit) of the operable display screen to display the monitoring variables, can display data according to actual configuration, and can satisfy the display of various data. In addition, analog index tables are used for displaying analog quantity data, such as data acquired by a sensor, indicator lamps are used for displaying some data, namely, the number of displayed monitoring variables is increased through combination of various display modes, and the types of the monitored variables are increased.
In addition, the server in the DAS can perform data storage operation, so that data support can be provided when fault problem analysis is performed.
The platform has a communication function, can send data to a human-machine interface unit (namely VDU) and an alarm management unit (arranged in a server) in a communication mode, and realizes display, recording and management of platform diagnosis data and key process parameters.
Specifically, the invention provides a diversity driving system and a diversity driving method, wherein the data acquisition module acquires target data, sends the target data to the display data determining module, sends a threshold processing result of the target data to the data processing module, the data processing module performs preset data processing operation on the threshold processing result to obtain data processing intermediate data and a data processing result, sends the data processing intermediate data and the data processing result to the display data determining module, and the display data determining module determines data to be displayed based on the target data, the data processing intermediate data and the data processing result, and the display module displays the data to be displayed. In the invention, the data display of the DAS is realized through the interaction flow of the data acquisition module, the data processing module, the display data determining module and the display module, so that the data monitoring operation can be performed based on the displayed data. In addition, in the invention, the server can store the target data, the data processing intermediate data and the data processing result so as to provide data support for analyzing the failure cause in failure.
Based on the foregoing, an embodiment of the present invention provides a diversity driving system, which may be configured on a hardware platform. Referring to fig. 2, the diversity driving system may include:
a data acquisition module 11, a data processing module 12, a display data determination module 13, and a display module 14;
the data acquisition module 11, the data processing module 12 and the display module 14 are respectively connected with the display data determination module 13; the data acquisition module 11 is connected with the data processing module 12.
In practical applications, the data acquisition module 11 is mainly used for performing data acquisition operation and threshold comparison operation. Specifically, target data is collected, the target data is sent to the display data determining module 13, and the threshold processing result of the target data is sent to the data processing module 12.
Taking fig. 3 as an example, the system level driving cabinet (SLAC) in fig. 3: the system level driving analog processing cabinet (SLAAC) and the system level driving digital processing cabinet (slaadc) are divided.
System level drive analog processing cabinet (SLAAC): the system comprises APUI/II/III, realizes acquisition and threshold processing of analog quantity ((such as sensor signals of temperature, liquid level, pressure and the like or platform diagnosis information)), and each realizes one instrument channel, wherein three instrument channels are totally arranged, as shown in APUI, APUII, APUIII, and an interface (such as a COM communication interface) for communicating with a server cabinet is designed.
System level drive digital processing cabinet (slaadc): including VLUA/VLUB and ALUA/ALUB, to implement voting of digital quantities, logical coincidence, etc.
In detail, the data acquisition module 11 may be, for example, a threshold comparison unit in fig. 3, configured to acquire data acquired by a sensor disposed in the DAS, and may also acquire platform diagnostic information, such as power failure information, board card virtual connection information, and the like. The threshold value comparing unit collects data collected by the sensor and platform diagnosis information together as target data, namely the target data comprises the platform diagnosis information and the data collected by the sensor arranged in the DAS.
In practical application, taking three paths of sensors S as an example, each path of sensors includes multiple paths of sub-sensors, for example, 20 sub-sensors, and data acquired by the 20 sub-sensors are output to a threshold comparison unit. The internal structures of the different sensors are the same. If the sensors are all 20 sub-sensors, the data objects acquired by each sub-sensor are the same, for example, in three sensors, the first sub-sensor acquires pressure data of the same equipment, the second sub-sensor acquires temperature data of the same equipment, the third sub-sensor acquires liquid level data of the same equipment, and the like.
In the threshold comparison unit, three APUs, namely APU I, APU II and APU III, are configured corresponding to the three sensors. Similarly, processing logic corresponding to each sub-sensor is also provided inside the three APUs, for example, 20 sub-APUs are included, and each sub-APU processes data collected by one sub-sensor.
Referring to FIG. 4, taking APU I as an example, the internal logic diagram is as follows:
the collected target data is used as analog quantity input AI and analog quantity output AO, then in the APU, the XU module obtains a set threshold value of the target data, the target data and the set threshold value are subjected to threshold value comparison processing, a threshold value processing result is obtained, and then the threshold value processing result is used as digital quantity output DO.
Subsequently, the analog input AI, the analog output AO, and the digital output DO are all output to the display data determining module 13 through a pre-configured communication interface (e.g. COM communication interface), and the display data determining module 13 may be a server as shown in fig. 3.
In addition, when a set threshold value of target data is acquired, the target data and the set threshold value are subjected to threshold value comparison processing, and after a threshold value processing result is obtained, the threshold value processing result is output to the data processing module 12.
After receiving the threshold processing result, the data processing module 12 performs a preset data processing operation on the threshold processing result to obtain data processing intermediate data and a data processing result, and sends the data processing intermediate data and the data processing result to the display data determining module 13.
Referring to fig. 3, the data processing module 12 may conform to the logic unit and drive the logic unit as in fig. 3.
In detail, the coincidence logic unit includes two paths, VLU a and VLU B, and the drive logic unit includes two paths, ALU a and ALU B.
And the VLU A and the VLU B in the coincidence logic unit are used for carrying out logic voting operation on the threshold processing result to obtain voting result data.
The logical voting operation may be as follows: 2oo3 voting logic, which can implement degradation processing, and for each sensor data, takes three output signals of APU I, APU II and APU III as input signals of VLU A and VLU B, and when the input values of any two of APU I, APU II and APU III are effective, the output result is 1; when one of the input signals fails, outputting a result of 1 when the remaining two effective signals are 1; when any two of the input signals fail, the output signal is directly 1. The output result in this embodiment is voting result data.
Referring to fig. 5, fig. 5 is a schematic diagram of logic inside VLU a, three output signals of APU I, APU II and APU III are taken as digital quantity inputs DI of VLU a and VLU B, and then voted by 2oo3 to obtain digital quantity output DO, in this embodiment, the voting result data and the threshold processing result are taken as data processing intermediate data.
And then, driving logic processing operation is carried out on the voting result data by using a driving logic unit, so as to obtain a data processing result.
Specifically, the logic coincidence of the driving logic in the driving logic unit is mainly processed by and gates, or gates, not gates, delay blocks, flip-flops (logic formed by combining sets of set priority flip-flops or reset priority flip-flops) and the like.
Referring to fig. 6, fig. 6 is a schematic diagram of the logic inside the ALU a in the driving logic unit, the digital output DO conforming to the logic is used as the digital input DI of the ALU a in the driving logic unit, and the digital output DO is obtained through the driving logic processing, and the digital output DO is the data processing result.
In practical application, the logic unit and the driving logic unit are divided into two columns A and B, and the logic processing modes of the columns A and B are the same as those of the logic processing modes of the columns A and B, as shown in VLUA, VLUB, ALUA and ALUB in fig. 3, after the logic implementation and processing of the columns A and B, the logic is sent to RGL (Rod Position Indicating and Rod Control System, rod control and rod position system), GSE (Turbine Protection System, automobile protection system) and non-safety control system F-SC3 DCS.
In another implementation of the present invention, the driving logic unit performs driving logic execution, and further uses system level manual operation information, which is generated when a user operates a manual operation switch or an operational display screen configured on the display module 14.
The display module 14 may be a DHP (Diverse HSI Panel, versatile human interface disk) as in fig. 3, which includes conventional devices and computer-like devices that together perform manual operation logic triggering and monitoring functions. Conventional devices include hard hand switches, photon boards, analog quantity indicators, and indicator lights. The computer-like device comprises 2 operable display screen VDUs as display and operating units. A graphic for manual operation (e.g., a pump valve on-off control graphic, a regulator valve PID (Proportional Integral Derivative) control graphic, etc.) is provided on the VDU.
An operator can obtain the generated system-level manual information through the operations of a hard manual switch arranged on the DHP disk table and the operations of on-off, adjustment and the like of a manual drawing control system on the VDU, and then drive logic processing operation is carried out on the system-level manual information and the voting result data to obtain a data processing result, and particularly, reference can be made to FIG. 3.
The display data determining module 13 in the present invention determines data to be displayed based on the target data, the data processing intermediate data, and the data processing result.
In practical application, the configuration operation is performed on the target data, the data processing intermediate data and the data processing result to obtain the data to be displayed.
Specifically, when the display data determining module 13 is a server, the server is disposed in the server cabinet SERC, so as to implement an alarm function, a data management function, an archiving function, and a comprehensive calculation function. The server cabinet deploys the server units, exchanges and other devices, receives signals from the system-level driving cabinet and the device-level driving cabinet, and can also receive the target data, the data processing intermediate data and the data processing results, perform summarization and configuration processing, and send the summarized and configuration processing to the VDU in the DHP for display.
In the configuration processing in this embodiment, some preset processing rules are configured, for example, when some data exist at the same time, which data is selected to display, or when some two data contradict, which data is selected to display, or data calculation operation is performed on a plurality of data, and data calculation results are displayed, where specific rules may be configured according to the actual configuration.
The data processed by the server can be output to the F-SC3 DCS system for corresponding control operation besides being displayed in the VDU.
In addition, the alarm management unit in the server can also store the target data, the data processing intermediate data and the data processing result so as to provide data support when fault analysis is carried out later.
When the data is stored, the corresponding data can be stored together for each device or system for the convenience of later data retrieval. In addition, for data security, encryption operations may be performed on the stored data.
After the data to be displayed is determined based on the server, the data to be displayed is displayed using the display module 14. The display module 14 may be a variety of human interface discs as described above. When the data to be displayed is displayed, the VDU is used for displaying. The VDU provides a list when displayed, and the technological parameters in two modes of drawing are displayed, so that operators can more intuitively check various variable information.
In addition, because the analog quantity indicator and the indicator lamp are further arranged in the diversity man-machine interface disc, the data (such as temperature, liquid level, pressure and other signals) collected by the sensor can be displayed by using the analog quantity indicator, and the analog quantity indicator can be displayed by outputting the data to the DHP through a conventional indicator communication link in FIG. 3. And in addition, the threshold processing result, the voting result data and part of data in the data processing result are displayed by using corresponding indicator lamps. And outputting to the DHP through an indicator lamp confirmation button for indicator lamp display. In general, the indication lamp displays the switch value input, such as a steam generator liquid level low alarm signal, a middle nuclear power high alarm signal, a main water supply flow signal and the like.
It should be noted that, in the data to be displayed, which are displayed by the analog quantity indicator, the indicator light and the VDU, there may be some same data, or the displayed data may be completely different, and may be specifically configured according to the actual configuration.
In another implementation of the present invention, referring to fig. 3, the diversity driving system further includes a manual control module, which may be the manual control station in fig. 3.
In practical application, the manual control station is arranged in a device-level driving cabinet (CLAC), and the device-level driving cabinet is used for realizing manual operation logic (specifically realized by the manual control station), equipment interface test related logic and an optical character plate alarm management function, and meanwhile, an interface for communicating with a server cabinet is designed to realize communication operation with a server.
The user may operate the hard hand-held switches disposed on the DHP table and the hand-held map control devices on the VDU, such as on-off, adjustment, etc. of the pump, at which time the hand-held control station receives device-level hand-held information generated by hand-held instructions when the user operates the hand-held switches or the operable display screens disposed on the display module 14.
And then performing manual logic processing operation on the equipment-level manual information to obtain equipment-level driving information.
Specifically, the manual control station is configured with corresponding manual logic, such as whether to respond and how to respond after receiving the equipment and the driving information. The method specifically comprises the following steps:
the order of response in receiving conflicting device level driver information, etc.
And the manual control station performs manual logic processing operation according to the corresponding manual logic to obtain equipment-level driving information. And then, acquiring system-level driving information determined based on the data processing result, wherein the data processing result can obtain the system-level driving information through execution and operation.
And carrying out priority processing operation on the equipment-level driving information and the system-level driving information to obtain a priority processing result.
In this embodiment, a priority order exists between the device-level driving information and the system-level driving information, for example, the system-level driving information is executed preferentially, or when the device-level driving information and the system-level driving information are contradictory, for example, the system-level driving information is a closed system, the device-level driving information is an open pump, and the two contradictions are mainly the system-level driving information.
