Detailed Description
The following describes the embodiments of the present invention further with reference to the drawings.
Method embodiment
The invention improves the initialization process of the information protection system in the current power system, mainly improves the initialization efficiency and reduces the initialization time by parallel execution of partial commands in the current initialization process. Specifically, a command is allocated for the initialization of each device, when the devices in the information protection system are initialized, the commands of the devices are controlled to run in parallel, the commands of each device comprise calling the self group title of the device, and then corresponding description and attribute calling are respectively carried out according to the called group title; and when the station in the information protection system is initialized, the command of each station comprises a calling station group header, the commands of each station are controlled to run in parallel, corresponding description and attribute calling are respectively carried out according to the called group header, if the description and attribute of the station relate to the return of the secondary device, and if the description and attribute of the station relate to the return of the secondary device, the command distributed for the device is called, and the commands are controlled to run in parallel.
Wherein each command (including a command of a station and a command of a device) is stored by adopting a database (such as redis) based on a Key-value type, wherein Key is a unique ID of the command, the value is stored in a json character string format, and a value storage structure in the Key-value database is shown in figure 1, wherein cmdList is all the transmitted commands; cmdMidList is a command that needs to be polled; cmdRecList is a command that has been returned; srrorinfo is anomaly information; sProcessInfo is process information and is stored into data according to the need; the sKey is a unique command identifier; status is a status identifier used to distinguish whether a command returns, succeeds, and fails; the veResult is the returned result set list, the content of which is determined by the business. Judging whether the currently called method, parameters, types, time and commands are successfully returned or not according to the data change of the List. The command states in the Key-value database are shown in FIG. 2.
As shown in fig. 4, the device initialization includes a method for calling the device group header and the description of the device, the device group header initialization and the description and the attribute initialization are designed as atomic services, each atomic service corresponds to a command, when the device needs to be initialized, the initialization commands of the devices are controlled to run in parallel, and the function of the device one-key initialization is to call the device group header first and then call the description and the attribute of the group. The initialization process of the station is as shown in fig. 5, to initialize the group header of the station first, the description and attribute are continuously initialized by calling the group header return of the station, and when the description and attribute of the station relate to the return of the secondary device, the device initialization function can be called. When the whole return state is 0, the initialization is completed, and the initialization of the station involves the loop nesting of the device initialization.
The specific process of initialization is shown in fig. 3, firstly judging whether skey is empty, if skey is empty, indicating that the device initialization process is started, generating a uuid as a key stored in redis, initializing status, cmdList, cmdMidList and cmdRecList as json character strings as value to be stored in redis, then setting status as 1, cmdList and cmdMidList as parameter list of sent command, and setting cmdRecList as empty. And returning the result including the key stored by redis and the corresponding state status to the client, and when the client judges that the key is not finished, assigning the key to the skey as an incoming parameter to continuously call the service. When the service is called again, the logic for judging redisl status is entered with skey. If status is 1, judging whether the sizes of cmdlist and cmdRecList are equal, if so, considering that the issued command is returned, setting status as 0 at the moment, and returning, if not, considering that the command is not returned, and returning the stored result set without modification; if status is 2, consider that the command has returned failure information, the command is considered complete, the current record in cmdMidList is removed, and a record is added in cmdRecList; if status is 0, the command is considered to be finished, whether the type of the current command needs to be issued by a subcommand is judged, if the type of the current command needs to be issued by a group subcommand, the process is called in a nested way, corresponding records are added in cmdList and cmdMidList in the current command, a new key-value pair is stored in redis to correspond to the command records, and if the type of the current command does not need to be issued by the group subcommand, the command is considered to be all ended.
