Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
The power grid monitoring system preposed service scheduling method based on load balancing distribution can be applied to the application environment shown in fig. 1. The application environment shown in fig. 1 includes a scheduling unit 102, a plurality of server instances 104, and a plurality of remote terminal units 106, wherein the scheduling unit 102 and the server instances 104, and the remote terminal units 106 and the server instances 104 communicate with each other via a network. The scheduling unit 102 generates a corresponding server instance sequence by sequencing the plurality of server instances 104, obtains a first number corresponding to the server instance sequence and a first terminal number of a current remote terminal unit 106 of a channel to be allocated, determines a first target server instance from the server instance sequence according to the first number and the first terminal number, and establishes a main channel between the first target server instance and the current remote terminal unit 106. By selecting a server instance from the sequence of server instances other than the first target server instance as the second target server instance and establishing a backup channel between the second target server instance and the current remote terminal unit 106. Where the remote terminal units 106 may be, but are not limited to, various personal computers, laptops, smartphones, tablets, and portable wearable devices, the server instances 104 may be implemented as individual servers or as a server cluster of multiple servers.
In an embodiment, as shown in fig. 2, a method for scheduling pre-service of a power grid monitoring system based on load balancing distribution is provided, which is described by taking the method as an example of being applied to a scheduling unit in fig. 1, and includes the following steps:
step S202, a plurality of server instances are sequenced, and a corresponding server instance sequence is generated.
Specifically, a corresponding server instance sequence is obtained by obtaining a plurality of connected server instances, obtaining the access time of each server instance, and further sequencing each server instance according to the access time of each server instance.
And sequencing each server instance in the server instance sequence according to the access time, and adding corresponding server numbers according to the access time.
In one embodiment, the plurality of server instances may also be randomly ordered, further generating a corresponding sequence of server instances.
Step S204, a first number corresponding to the server instance sequence and a first terminal number of a current remote terminal unit of the channel to be distributed are obtained.
Specifically, the number of server instances in the server instance sequence, i.e., the first number, is obtained, and the first terminal number of the current remote terminal unit to which the channel is to be allocated is obtained. Wherein, the first number and the first terminal number can be any natural number different from 0, such as 1, 2, 3, 4, 5 … …
And step S206, determining a first target server instance from the server instance sequence according to the first quantity and the first terminal number.
Specifically, a remainder operation is performed on the first terminal number and the first number to generate a corresponding first remainder, and then a first target server instance is determined from the server instance sequence according to the first remainder. Wherein the first remainder may be any natural number.
In one embodiment, when the first terminal number is M, the first number is N, and the first remainder is K, the first remainder K obtained by dividing the first terminal number M by the first number N is calculated by performing a remainder operation on the first terminal number and the first number, and the first target server instance is determined from the server instance sequence according to the first remainder K.
Further, according to the first remainder K, a K +1 th server instance is determined from the server instance sequence and is used as a first target server instance.
For example, when the first number N is 4 and the first terminal number M is 1, the first remainder K is calculated to be 1, and then the K +1 th server instance, i.e. the 2 nd server instance, is determined from the server instance sequence as the first target server instance according to the first remainder K.
Step S208, an active channel is established between the first target server instance and the current remote terminal unit.
Specifically, a primary channel is established between the first target server instance and the current remote terminal unit based on a first association relationship by acquiring a first server number corresponding to the first target server instance and establishing the first association relationship between the first server number and the first terminal number. The first server number may also be any natural number other than 0.
For example, when the first server number is F1 and the first terminal number is M, the primary channel is established between the first target server instance and the current remote terminal unit by establishing the first association relationship between the first server number F1 and the first terminal number M, and further based on the first association relationship.
In an embodiment, the method for scheduling pre-services of a power grid monitoring system based on load balancing allocation in the present application is applied to a digital power grid scheduling system, and as shown in fig. 3, a schematic diagram of the digital power grid scheduling system after main channel allocation is performed is provided, as can be seen from fig. 3, a scheduling unit of the digital power grid scheduling system is connected to multiple server instances, and a main channel is established between each server instance and a corresponding determined remote terminal unit, that is, a solid arrow between a server instance and a remote terminal unit is used to indicate the main channel.
Specifically, when the scheduling unit needs to allocate channels to a plurality of remote terminal units, first, a plurality of server instances are sorted to generate a corresponding server instance sequence, and a first number N corresponding to the server instance sequence is obtained, as can be known by referring to fig. 3, N may be 4. Then, the scheduling unit obtains a first terminal number M of the current remote terminal unit of the channel to be allocated, that is, obtains an mth remote terminal unit of the current channel to be allocated, and calculates a first remainder K after M is divided by N. Illustratively, for the 1 st remote terminal unit, the first remainder K is 1, and then the scheduling unit selects the 1 st +1 st-2 server instance from the sorted multiple server instances as the first target server instance, and establishes an active channel between the 1 st remote terminal unit and the first target server instance, that is, establishes an active channel between the 1 st remote terminal unit and the 2 nd server instance.
Similarly, for the 2 nd to 6 th remote terminal units shown in fig. 3, corresponding first remainders are respectively calculated, and then according to the calculated first remainders, a first target server instance is determined in the server instance sequence, and an active channel is established between the first target server instance and the current remote terminal unit.
Step S210, selecting a server instance other than the first target server instance from the server instance sequence as a second target server instance.
Specifically, any one of the server instances except the first target server instance may be randomly selected from the server instance sequence as the second target server.
In one embodiment, a corresponding second remainder is generated by obtaining a second terminal number corresponding to a remote terminal unit adjacent to the current remote terminal unit and performing a remainder operation on the second terminal number and the first number, and a server instance other than the first target server instance is determined from the server instance sequence according to the second remainder as a second target server instance. Wherein the second remainder may be any natural number.
Specifically, when the first terminal number corresponding to the current remote terminal unit is M, the second terminal number corresponding to the remote terminal unit adjacent to the current remote terminal unit includes M-1 and M +1, and the corresponding second remainder a may be generated by performing a remainder operation on the second terminal number M +1 and the first number, or the corresponding second remainder B may be generated by performing a remainder operation on the second terminal number M-1 and the first number.
Wherein the server instance other than the first target server instance may be determined from the sequence of server instances based on the second remainder a, or the server instance other than the first target server instance may be determined from the sequence of server instances based on the second remainder B.
Further, based on the second remainder a, an a +1 th server instance may be determined from the sequence of server instances as a second target server instance. Wherein the A +1 th server instance is not the first target server instance.
Likewise, based on the second remainder B, a B +1 th server instance may be determined from the sequence of server instances as a second target server instance. Where the B +1 th server instance is not the first target server instance.
In step S212, a backup tunnel is established between the second target server instance and the current remote terminal unit.
Specifically, a second server number corresponding to a second target server instance is obtained, a second association relationship between the second server number and the first terminal number is established, and then a standby channel is established between the second target server instance and the current remote terminal unit based on the second association relationship.
For example, when the second server number is F2 and the first terminal number is M, a backup path is established between the second target server instance and the current remote terminal unit by establishing a second association relationship between the second server number F2 and the first terminal number M, and further based on the second association relationship.
In an embodiment, the method for scheduling pre-services of a power grid monitoring system based on load balancing allocation in the present application is applied to a digital power grid scheduling system, and as shown in fig. 4, a schematic diagram of the digital power grid scheduling system after standby channel allocation is provided, as can be seen in fig. 4, a scheduling unit of the digital power grid scheduling system is connected to multiple server instances, and when a first target server instance is determined, a main channel is established between each server instance and a corresponding determined remote terminal unit, that is, a solid arrow between a server instance and a remote terminal unit is used to indicate the main channel.
Further, a first terminal number corresponding to the current remote terminal unit is M, a second terminal number corresponding to a remote terminal unit adjacent to the current remote terminal unit includes M +1, a corresponding second remainder a is generated by performing a remainder operation on the second terminal number M +1 and the first number N, and further based on the second remainder a, an a +1 th server instance may be determined from the server instance sequence as a second target server instance, and a backup tunnel is further established between the second target server instance and the current remote terminal unit, that is, a dashed arrow between the server instance and the remote terminal unit represents the backup tunnel.
Illustratively, for a remote terminal unit with a first terminal number of 1, that is, the 1 st remote terminal unit, the scheduling unit obtains a second remainder a after M +1 is divided by N by calculation, that is, after 1+1 is divided by 4, the remainder a is 2, and then the scheduling unit selects the 2+1 st server instance from the sorted multiple server instances as a second target server instance, and establishes a standby channel between the 1 st remote terminal unit and the second target server instance, that is, establishes a standby channel between the 1 st remote terminal unit and the 3 rd server instance.
Similarly, for the remote terminal units from 2 nd to 6 th as shown in fig. 4, corresponding second remainders a are respectively calculated, and then a second target server instance is determined in the server instance sequence according to the calculated second remainders a, and a standby channel is established between the second target server instance and the current remote terminal unit.
In an embodiment, the method for scheduling pre-services of a power grid monitoring system based on load balancing distribution in the present application is applied to a digital power grid scheduling system, as shown in fig. 5, a schematic diagram of another digital power grid scheduling system after performing allocation of standby channels is provided, as can be seen from fig. 5, a scheduling unit of the digital power grid scheduling system is connected to a plurality of server instances, and when a first target server instance is determined, a main channel is established between each server instance and a corresponding determined remote terminal unit, that is, a solid arrow between the server instance and the remote terminal unit is used to represent the main channel.
Further, a first terminal number corresponding to the current remote terminal unit is M, a second terminal number corresponding to a remote terminal unit adjacent to the current remote terminal unit includes M-1, a corresponding second remainder B is generated by performing a remainder operation on the second terminal number M-1 and the first number N, and then based on the second remainder B, a B +1 th server instance can be determined from the server instance sequence to serve as a second target server instance, and a standby channel is further established between the second target server instance and the current remote terminal unit, that is, a dashed arrow between the server instance and the remote terminal unit represents the standby channel.
Illustratively, for a remote terminal unit with a first terminal number of 1, that is, the 1 st remote terminal unit, the scheduling unit obtains a second remainder B after dividing M-1 by N through calculation, that is, after calculating 1-1 by 4, the remainder B is 0, and then the scheduling unit selects the 0+1 th server instance from the sorted multiple server instances as a second target server instance, and establishes a standby channel between the 1 st remote terminal unit and the second target server instance, that is, establishes a standby channel between the 1 st remote terminal unit and the 1 st server instance.
Similarly, for the 2 nd to 6 th remote terminal units shown in fig. 5, the corresponding second remainder B is calculated respectively, and then a second target server instance is determined in the server instance sequence according to the calculated second remainder B, and a standby channel is established between the second target server instance and the current remote terminal unit.
In the power grid monitoring system preposed service scheduling method based on load balancing distribution, a plurality of server instances are sequenced to generate a corresponding server instance sequence, a first number corresponding to the server instance sequence and a first terminal number of a current remote terminal unit of a channel to be distributed are obtained, and then a first target server instance is determined from the server instance sequence according to the first number and the first terminal number. And establishing a primary channel between the first target server instance and the current remote terminal unit. By selecting a server instance other than the first target server instance from the sequence of server instances as a second target server instance and establishing a backup path between the second target server instance and the current remote terminal unit. When data transmission and channel distribution are carried out between a plurality of remote terminal units and a plurality of server instances, due to the fact that manual channel distribution is not needed, the problem of channel repeated distribution caused by repeated distribution or distribution error and leakage can be avoided, required power data are transmitted on time, and power data transmission efficiency is further improved.
In an embodiment, as shown in fig. 6, the step of selecting a server instance other than the first target server instance from the server instance sequence as the second target server instance specifically includes:
step S602, a second terminal number corresponding to a remote terminal unit adjacent to the current remote terminal unit is acquired.
Specifically, when the first terminal number corresponding to the current remote terminal unit is M, that is, when the current remote terminal unit is the mth remote terminal unit, the second terminal number corresponding to the remote terminal unit adjacent to the current remote terminal unit includes M-1 and M +1, that is, the adjacent remote terminal unit includes the M-1 remote terminal unit and the M +1 remote terminal unit.
Step S604, a remainder operation is performed on the second terminal number and the first number to generate a corresponding second remainder.
Specifically, the remainder operation may be performed on the second terminal number M +1 and the first number N to generate a corresponding second remainder a, or the remainder operation may be performed on the second terminal number M-1 and the first number N to generate a corresponding second remainder B.
Illustratively, for the remote terminal unit with the first terminal number 1, that is, the 1 st remote terminal unit, the scheduling unit obtains the second remainder a after dividing M +1 by N by calculation, that is, after calculating 1+1 by 4, the remainder a is 2.
Similarly, for the remote terminal unit with the first terminal number 1, i.e. the 1 st remote terminal unit, the scheduling unit obtains the second remainder B of M-1 divided by N by calculation, i.e. obtains the remainder B equal to 0 after 1-1 is divided by 4.
Step S606, according to the second remainder, determining a server instance other than the first target server instance from the server instance sequence as a second target server instance.
In particular, server instances other than the first target server instance may be determined from the sequence of server instances based on the second remainder a, or determined from the sequence of server instances based on the second remainder B.
Further, based on the second remainder a, an a +1 th server instance may be determined from the sequence of server instances as a second target server instance. Wherein the A +1 th server instance is not the first target server instance.
Illustratively, for a remote terminal unit with a first terminal number of 1, that is, the 1 st remote terminal unit, the scheduling unit obtains a second remainder a after M +1 is divided by N by calculation, that is, after 1+1 is divided by 4, the remainder a is 2, and then the scheduling unit selects the 2+1 st server instance from the sorted multiple server instances as a second target server instance, and establishes a standby channel between the 1 st remote terminal unit and the second target server instance, that is, establishes a standby channel between the 1 st remote terminal unit and the 3 rd server instance.
Likewise, based on the second remainder B, a B +1 th server instance may be determined from the sequence of server instances as a second target server instance. Wherein the B +1 th server instance is not the first target server instance.
For a remote terminal unit with the first terminal number of 1, namely, the 1 st remote terminal unit, the scheduling unit obtains a second remainder B after M-1 is divided by N through calculation, namely, after 1-1 is divided by 4, the remainder B is obtained to be 0, and then the scheduling unit selects the 0+1 th server instance from the sorted multiple server instances as a second target server instance, and establishes a standby channel between the 1 st remote terminal unit and the second target server instance, namely, establishes a standby channel between the 1 st remote terminal unit and the 1 st server instance.
In this embodiment, a corresponding second remainder is generated by obtaining a second terminal number corresponding to a remote terminal unit adjacent to the current remote terminal unit and performing a remainder operation on the second terminal number and the first number, and then a server instance except for the first target server instance can be determined from the server instance sequence according to the second remainder to serve as a second target server instance.
