Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
FIG. 1 is a flow chart illustrating a method for nuclear power process plant redundancy association in accordance with an exemplary embodiment. The method may be executed by a terminal device, for example, the terminal device may be a server, a desktop computer, or the like, and the type of the terminal device is not limited in the embodiments of the present disclosure. As shown in fig. 1, the method may include:
and 100, screening a plurality of devices which belong to the same system and have the same type from the nuclear power plant devices.
For example, the system in which the device operates and the model of the device may be identified in advance, and a plurality of devices belonging to the same system and having the same type may be obtained by screening according to the system in which the device operates and the model of the device.
For example, step 100 may include:
1001, acquiring code numbers of all equipment of a nuclear power plant;
step 1002, when it is detected that characters of preset sequence intervals in the codes of a plurality of devices are the same, determining that the plurality of devices belong to the same system and are of the same type.
For example, nuclear power generating units and equipment all have corresponding codes, and according to the encoding rule of the existing nuclear power generating units, the nuclear power generating units and equipment adopt the following structure, such as 1AAA001VL, wherein the codes comprise a unit number + a system name (3 letters) + a number (3 numbers) + an equipment type (the number of digits is indefinite). The codes of the devices which are redundant with each other have correlation, generally speaking, a plurality of devices which are redundant with each other are distributed in the same system, the system names are the same, namely the 2 nd to 4 th bits of the device codes are the same; secondly, the redundant equipment has the same function, so that the equipment types are the same, namely the 8 th bit to the last bit of the equipment code number are the same; therefore, if the symbols of the 2 nd bit to the 4 th bit of the code numbers of two devices are the same, and the symbols from the 8 th bit to the last bit are the same, the two devices have high probability of being a redundant device group each other.
Therefore, the coding rule of the code number of the nuclear power plant equipment and the characteristics of the mutual redundant equipment are utilized, other information of the equipment is not needed, and the equipment with high probability of mutual redundancy is screened out only through the specific sequence interval of the code number of the equipment, so that the subsequent calculated amount is greatly reduced.
And 102, setting the two devices as mutually redundant devices under the condition that the parameters of the two devices are judged to accord with the switching fluctuation condition.
For example, step 102 may include: under the condition that the parameters of the two devices exceed the preset threshold range, if the running states of the two devices are mutually exclusive and the parameter of one of the two devices within the preset time length after the abnormal time returns to the preset threshold range, the two devices are set as devices which are redundant with each other, and the abnormal time is the sampling time corresponding to the parameter exceeding the preset threshold range.
For example, a device whose parameter exceeds the preset threshold range may be screened, and then, if two devices whose operation states are mutually exclusive are obtained by screening, it may be determined whether a parameter of one of the two devices in the preset time period after the abnormal time returns to the preset threshold range again (for example, a parameter corresponding to a sampling time in the preset time period after the abnormal time returns to the preset threshold range again), where the abnormal time is the sampling time corresponding to the parameter exceeding the preset threshold range. And when determining that the parameter of one of the two devices within the preset time length after the abnormal time returns to the preset threshold range again, setting the two devices as devices which are redundant with each other.
The method comprises the steps of screening a plurality of devices belonging to the same system and having the same type, obtaining parameters corresponding to the devices and related to a steady state, and setting the two devices as devices which are mutually redundant under the condition that the parameters of the two devices are judged to accord with a switching fluctuation condition. Therefore, the switching rule is learned by acquiring the relevant information of the equipment from the real-time network data stream, and the learning result is used as the equipment switching group to provide a reference basis for judging the running state of the unit.
In one possible implementation, the method further includes:
and 103, under the condition that the plurality of devices and the same target device are judged to be mutually redundant, setting the plurality of devices and the target device as mutually redundant devices.
Therefore, a plurality of devices which are redundant with each other can be associated more comprehensively, so that the method disclosed by the invention can be widely applied to redundant configuration scenes of one-use multiple-standby, one-use multiple-standby and multiple-use multiple-standby of the nuclear power plant.
In one possible implementation manner, there is provided a nuclear power process equipment redundancy association apparatus, including:
the screening module is used for screening a plurality of devices which belong to the same system and are of the same type from the nuclear power plant devices;
an obtaining module, configured to obtain, for the multiple devices, a parameter of each device, where the parameter of each device is related to a steady state of the device;
and the association module is used for setting the two devices as the devices which are redundant to each other under the condition that the parameters of the two devices are judged to accord with the switching fluctuation condition.
In one possible implementation, the screening module includes:
the acquisition submodule is used for acquiring the code of each device of the nuclear power plant;
and the determining submodule is used for determining the plurality of devices as the same system and the same type under the condition of detecting that the characters of the preset sequence intervals in the codes of the plurality of devices are the same.
In one possible implementation, the association module includes:
and the association submodule is used for setting the two devices as mutually redundant devices if the running states of the two devices are mutually exclusive and the parameter of one of the two devices in the preset time length after the abnormal time is returned to the preset threshold range under the condition that the parameters of the two devices are detected to exceed the preset threshold range, wherein the abnormal time is the sampling time corresponding to the parameter exceeding the preset threshold range.
In one possible implementation, the apparatus further includes:
and the adding module is used for setting the multiple devices and the target device as devices which are redundant with each other under the condition that the multiple devices and the same target device are judged to be redundant with each other.
