Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Fig. 1 is a flowchart of a first embodiment of a control method for a plant unit according to the present invention, and as shown in fig. 1, the control method for a plant unit according to this embodiment may specifically include the following steps:
100. if a starting request of the multi-machine online equipment is received, randomly starting a reference online machine set in M online machine sets in the multi-machine online equipment;
in a specific implementation process, in order to prevent that the running time of a part of the unit sets is too long and the running time of the part of the unit sets is too short, the running time of each unit set needs to be balanced, for a plurality of unit sets, the probability of each unit set being selected is the same from the point of view of probability, that is, as long as one unit set is randomly started, the number of times of each unit set being selected is closer and closer as the number of times increases, and the acting objects of each unit set are the same, which means that the using time of each unit set is the same and close, therefore, the running time of each unit set is necessarily balanced as the number of times increases. Therefore, in the embodiment, based on the principle, the equalization processing of each unit of the multi-unit online equipment can be realized.
Specifically, in this embodiment, when the user needs to use the multi-machine online device, the user may initiate a power-on request of the multi-machine online device through a remote controller, an operation panel, and the like. Therefore, if a starting request of the multi-machine online equipment is received, one online machine set in the M online machine sets can be randomly started to serve as a reference online machine set, and the times of selecting each online machine set as the reference online machine set are approximately the same along with the increase of the starting times. Wherein M is an integer greater than 2.
It should be noted that, in a normal situation, all the units of the multi-machine online device are started up only under a normal condition, that is, in a normal situation, all the units of the multi-machine online device are online units, and the number of times that each unit is selected as a reference online unit is approximately the same. Even if some units of the multi-unit online equipment are abnormal under a special condition and do not belong to the online units in one statistical process, the selection times of some abnormal units are similar to the selection times of other units along with the use time evidence of the multi-unit online equipment.
101. Determining target operation requirements of the multi-machine online equipment;
in practical application, if a user needs to use the multi-machine online device, the user often needs to send own requirement information to the multi-machine online device while sending a startup request or after sending the startup request. For example, the number of the units that need to be started, which mode the multi-unit online device needs to operate in, etc. Therefore, the target operation requirement of the multi-machine online equipment can be further determined according to the requirement information input by the user. For example, target operation requirements such as power of the multi-machine online equipment and the number of the operating units can be determined according to the number of the started units input by the user, which mode the multi-machine online equipment needs to work in, and the like.
It should be noted that this embodiment does not limit the sequence of the step and the operation of "randomly starting one reference online unit of the M online units in the multi-machine online device" in step 100.
102. Determining N online units needing to be started according to the target operation requirements of the multi-unit online equipment;
in this embodiment, after the target operation requirement of the multi-machine online device is determined, the N online machine sets to be started may be determined according to the target operation requirement of the multi-machine online device. N is a positive integer, and N is less than or equal to M.
For example, if the target operation requirement of the multi-machine online device is the number of the operation machine sets, the N online machine sets that need to be started can be directly determined. If the target operation requirement of the multi-machine online equipment is the load capacity of the multi-machine online equipment, conversion can be carried out according to the rated power of each online unit and the load capacity of the multi-machine online equipment, and therefore the N online units needing to be started are determined.
103. Judging whether the number N of the online units is equal to 1 or not; if yes, go to step 104, if no, go to step 105;
in practical application, at least one unit runs when the multi-unit online device runs, and in this embodiment, one online unit is randomly started each time, so that the running condition of other online units does not need to be considered when only one unit runs, and if the multi-unit online device needs more than two online units to run, the running condition of other online units needs to be considered to ensure that each unit is subjected to balanced processing. If yes (N ═ 1), step 104 is executed, and if no (N > 1), step 105 is executed.
104. Controlling the operation of a reference online unit;
if N is 1, the reference online unit only needs to be controlled to operate so as to meet the target operation requirement of the multi-unit online equipment.
105. And respectively controlling the operation of the reference online unit and N-1 target online units selected from the M online units.
If N is greater than 1, N-1 target online units need to be selected from the M online units, in this embodiment, in order to ensure that the operation time of each unit is similar or the same in the later period, when selecting the N-1 target online units, the selection needs to be performed according to the following rules: the serial numbers of the N-1 target online units are adjacent in sequence, and the serial number of the first target online unit in the N-1 target online units is adjacent to the serial number of the reference online unit.
After N-1 target online units are selected, the reference online units and N-1 target online units in the M online units are respectively controlled to operate so as to meet the target operation requirement of the multi-machine online equipment.
In this embodiment, each time the multi-machine online device is started, the operations are performed according to the above steps, and since the function objects of the multi-machine online device are the same, the conditions for reaching the target operation requirement are basically the same, that is, the time for each unit to reach the target operation requirement is basically the same, so that the operation time of each unit approaches the same as the number of times of use is increased, and the purpose of balancing the operation time of each unit in the multi-machine online device is achieved on the premise of not counting the operation time of each unit.
In the unit control method of this embodiment, if a startup request of a multi-machine online device is received, a reference online unit of M online units on line in the multi-machine online device is randomly started; after the target operation requirement of the multi-machine online equipment is determined, N online machine sets needing to be started are determined according to the target operation requirement of the multi-machine online equipment; if N is equal to 1, controlling the reference online unit to operate; if N is larger than 1, selecting N-1 target online units with sequentially adjacent serial numbers from the M online units; the operation of the reference online unit and the N-1 target online units is respectively controlled, so that the operation time of each unit is subjected to balanced control as the selected times of each unit are approximately the same as the selected times of the multi-unit online equipment are increased on the premise that the selected probability of each online unit is the same and the action object of each unit is the same. By adopting the technical scheme of the invention, the running time of each unit can be controlled in a balanced manner on the premise of not recording the running time of each unit and not calculating, so that the memory space occupied by the controller is reduced, and the control efficiency of the units is improved.
Fig. 2 is a flowchart of a second embodiment of the method for controlling a plant unit according to the present invention, and as shown in fig. 2, the method for controlling a plant unit according to this embodiment further describes the technical solution of the present invention in more detail based on the embodiment shown in fig. 1.
As shown in fig. 2, the method for controlling the unit of this embodiment may specifically include the following steps:
200. if a starting request of the multi-machine online equipment is received, adding all the units meeting the starting condition in the multi-machine online equipment into a sequencing queue;
in a specific implementation process, if a startup request of the multi-machine online equipment is received, the related information of all the units can be acquired, so that all the units meeting the startup condition are selected from the information as online units, and all the units meeting the startup condition in the multi-machine online equipment are added into a sequencing queue. For example, the X unit may be in a maintenance state or a fault state, and the X unit does not satisfy the start condition, and cannot be used as an online unit, and other units except the X unit may be used as online units.
201. Numbering the units added into the sequencing queue to obtain M online units numbered from 1 to M;
in this embodiment, after all the units meeting the start condition are added into the sorting queue, the units may be numbered according to the order of addition, so as to obtain M online units numbered from 1 to M. Wherein M is an integer greater than 2.
It should be noted that, in this embodiment, since all the units can meet the starting condition under most conditions, each unit in this embodiment may set a fixed code, and when adding into the sorting queue, the units are added in the order from small to large in number, and after adding all the units meeting the starting condition into the sorting queue, the process of coding may be omitted, and the fixed code of each unit may be directly called. If part of the units do not meet the starting condition, the serial numbers can be added according to the sequence from small to large, and then the serial numbers can be added according to the sequence of the serial numbers.

In this embodiment, the numbers of the N-1 target online units may be sequentially incremented, and when the number is increased to M, the number 1 is selected in a loop and then incremented. The serial numbers of the N-1 target online units can also be sequentially decreased progressively, and when the serial numbers are decreased to 1, the serial numbers M are selected in a circulating manner and then are continuously decreased progressively.
Specifically, the number a of the reference on-line unit and the number b of the ith target on-line unit may be setiWherein i is a positive integer, and i is less than or equal to N-1. In this embodiment, if a is equal to M, N-1 serial numbers b are selected from M online units according to a first preset formulaiIn order of adjacent meshMarking on-line units; the first predetermined formula is biI; wherein, biThe number of the ith target online unit is N-1, wherein i is a positive integer and is smaller than or equal to N; if a is less than M and N is less than or equal to M-a +1, selecting N-1 serial numbers b from M online units according to a second preset formulaiThe target online units are adjacent in sequence; the second preset formula is as follows; biA + i; if a is less than M and N is more than M-a +1, selecting N-1 serial numbers b from M online units according to a third preset formulaiThe target online units are adjacent in sequence; the third preset formula is:

for example, if M is 7, a is 7, and N is 3. The numbers of the two target online units are 1 and 2 in sequence. If M is 7, a is 3, and N is 3, the numbers of the two target on-line units are 4 and 5 in sequence.

210. Determining the shutdown requirement of the multi-machine online equipment;
if the unit stop operation instruction does not carry the number of the shutdown unit, the shutdown requirement of the multi-machine online equipment can be determined according to the requirement input by the user. This process is similar to determining the operational requirements of the multi-machine online devices, e.g., the user's requirements indicate that the load on the multi-machine online devices is less than the power output by the currently operating group, and the corresponding operating group may be reduced.
211. Determining P units to be shut down which need to be shut down according to the shut down requirement of the multi-unit online equipment;
in a specific implementation process, determining P units to be shut down which need to be shut down according to the shutdown requirement of the multi-machine online equipment; wherein P is a positive integer and is less than or equal to N-1.
