Example one
Fig. 1 is a schematic flow diagram illustrating a definable time task propelling method provided by the present invention, fig. 2 is a schematic diagram illustrating a system time service between servers in the definable time task propelling method provided by the present invention, and fig. 3 is a schematic diagram illustrating a system structure for implementing the definable time task propelling method provided by the present invention. The definable time task propelling method based on automatic circulation provided by the embodiment comprises the following steps.
S101, after receiving a newly created recording task, a task server registers a task node timer for a task node of the recording task according to a user-defined task node time length and a user-defined timing step length in the recording task, configures a natural time timer according to the user-defined timing step length, and then synchronously starts the task node timer and the natural time timer.
In the step S101, the recording task may be, but is not limited to, created by a task performer or a task attendee (e.g., a superior leader of the task performer), and transmitted to the task server after being created, and then automatically supervised by the task server. Meanwhile, in the recording task creating process, besides creating necessary recording task content, a custom task node time length and a custom timing step length can be preset for a task node of a recording task, wherein the time unit of the custom timing step length can be but is not limited to nanosecond, microsecond, millisecond, second, minute or hour, and the like, so that the former is, for example, a natural day, and the latter is, for example, a quarter (namely, 15 minutes).
In step S101, the task node timer is configured to perform timing of processing progress on a task node that records a task, so as to determine whether the task node is not processed after an expiration. And the natural time timer is used for timing for recording the natural time. Optimally, in order to more intuitively show the processing progress of the recording task on the display page, the task node timer can be preferably a counter-clockwise countdown timer, and the natural time timer can be preferably a clockwise timer. In addition, the natural time timer can be further designed into a large-inner-diameter annular structure, and the task node timer is designed into a small-outer-diameter annular structure which is built in the natural time timer, so that the display effect of recording the processing progress of the task is more visual.
In order to ensure high accuracy of timing and time keeping accuracy, it is necessary to synchronize the time of the task server in the following steps before step S101.
S201, the time publishing server periodically sends a first time T to the time subscribing server according to a predefined time publishing periodSDTThe time service of (1) issuing the message, wherein the time subscription server is a task server, and the first time T isSDTThe calculation formula of (a) is as follows:
TSDT＝T1+tFPSAB+t′COR
in the formula, T1Publishing servers for timeThe instant local system time t when the first bit code of the time service release message is sentFPSABIs the sending time length, t 'of the time service release message'CORThe corrected transmission delay obtained after the previous time service is provided for the time release server, and if the previous time service is not provided, the corrected transmission delay is a default value or 0.
In step S201, the task server needs to complete an automatic registration subscription in the time distribution server according to the configuration information in advance, and becomes a time subscription server, so as to periodically receive the time service distribution packet. After the registration subscription is completed, in order to ensure the transmission timeliness and security of the time service release message and the subsequent time service confirmation message, an SSH (Secure Shell protocol) information tunnel needs to be established between the time release server and the time subscription server in advance, and then the time service release message and the subsequent time service confirmation message are transmitted through the SSH information tunnels established between every two servers. In addition, the predefined time distribution period can be manually set in advance, for example, set to an hour level capable of meeting the requirement of low-precision time service time, or set to a microsecond level capable of meeting the requirement of high-precision time service time. Also the first time TSDTThe time accuracy of (d) may be set to be predefined in nanoseconds, microseconds, milliseconds, seconds, or the like.
Before the step S201, in order to make the time distribution server have a high-accuracy local system time, the method further includes the following steps: s200, the Time publishing server periodically accesses an NTP (Network Time Protocol) Time server according to a predefined Time updating period, acquires NTP Time and then updates local system Time into the NTP Time. The NTP time server is a special time server which is authoritative to the Internet and used for timing aiming at a computer, a control device and the like in an automation system.
S202, after receiving the time service release message, the time subscription server updates the local server time to the first time TSDTAnd feeds back the time release server including the second time TREINThe time service confirmation message of (2), wherein the second time TREINThe calculation formula of (a) is as follows:
TREIN＝TSDT+tR+tFSPBA
in the formula, tRResponse delay for time subscription server, tFSPBAAnd confirming the sending time length of the message for the time service.
S203, after receiving the time service confirmation message, the time release server calculates the corrected transmission delay t after the time service according to the following formulaCOR：
tCOR＝(TRDT-T1-tFPSAB-tR-tFSPBA)/2
In the formula, TRDTThe time distribution server is the instant local system time when receiving the last bit code of the time service confirmation message;
s204, the time release server updates and stores the corrected transmission delay t obtained after the time service is carried out for the timeCOR。
As shown in fig. 2, the corrected transmission delay tCORI.e. the transmission delay t of the time service release messageDABAnd time service confirmation message transmission delay tDBAAverage value of, i.e. tCOR＝(tDAB+tDBA) (ii)/2, reflecting the level of transmission delay between the most recent time-publishing server and the time-subscribing server, thereby passing through the aforementioned steps S201-S204, and at the first time TSDTTakes the corrected transmission delay t 'of the previous time service into consideration'CORThe time synchronization accuracy of the time subscription server and the time publishing server after time service can be ensured.
S102, when the task server finds that the task executor still does not process the recording task when the timing of the task node timer is reached, the instant natural time of the natural time timer is used as a dequeue time node, and then the dequeue time node is added into a dequeue time node list queue.
And S103, when the streaming server monitors that a new dequeuing time node appears in the dequeuing time node list queue without clearance, generating a corresponding task propulsion event, accessing the information server according to the corresponding recorded task, and acquiring the execution content of the corresponding task propulsion event and the receiving address of a task attendee to be reminded.
In the step S103, the task pushing event execution content, the receiving address of the to-be-reminded task attendee, and the mapping relationship between the to-be-reminded task attendee and the corresponding recorded task need to be stored in the information server in advance (which may be earlier than the creation time of the corresponding recorded task), where the task pushing event execution content may be, but is not limited to, "call-reminding task performer", "skip task performer", "delay task node duration", or "change task performer", and the receiving address of the to-be-reminded task attendee may be, but is not limited to, a computer IP address, an email address, or a contact phone number of the task attendee. Thus, after the step S103, the flow server may further determine the priority level of the corresponding task promoting event according to the task promoting event execution content, so as to flexibly adjust the dispatching order of the task promoting event execution content according to the actual situation, for example, for the task promoting event execution content being "change task performer", the priority level of the corresponding task promoting event may be determined to be 1 level; for the task propulsion event execution content of 'delaying task node duration', the priority dispatching level of the corresponding task propulsion event can be determined to be 2 level; for task push event execution content that is a "phone-reminded task performer" or a "skip task performer," the priority assignment level for the corresponding task push event can be determined to be level 3 (i.e., the highest level). In addition, the time synchronization method between the circulation server and the information server and the time distribution server may also be, but is not limited to, the manner described in steps S201 to S204, that is, the circulation server and the information server are respectively used as time subscription servers to perform subscription-type service, and details thereof are not repeated herein.
And S104, the flow server takes the task propulsion event as an event processing thread, adds the event processing thread into an event processing thread pool, and dispatches the execution content of the task propulsion event to the task followers corresponding to the receiving addresses of the task followers according to the early and late sequence of the dequeuing time nodes corresponding to the task propulsion event.
In the step S104, the event processing thread pool is used for being responsible for dispatching task pushing events, and if a priority dispatching level of task pushing events is determined, after the step of adding the task pushing events into the event processing thread pool as an event processing thread, the method further includes the following steps: according to the priority dispatching level and the dequeuing time node of the task propulsion event, all the event processing threads which are not dispatched in the event processing thread pool are sequenced as follows by an event level weight thread pool: and arranging the event processing thread with the highest priority dispatching level at the forefront of the thread queue, and arranging the event processing thread with the earliest dequeuing time node at the forefront of the thread queue with the same priority dispatching level. The event level weight thread pool is used for adjusting the dispatching sequence of all the event processing threads which are not dispatched in the event processing thread pool, so that task propulsion reminding can be carried out according to priority and early, and the timeliness of task propulsion is ensured. Preferably, the event level weight thread pool communicates with the event processing thread pool via pipeline threads. The pipeline thread is used for realizing the communication between the event level weight thread pool and the event processing thread pool so as to adjust the dispatching sequence of all the event processing threads.
Therefore, through the steps S101 to S104, a task flow system capable of automatically circulating and a distributed distribution system for realizing task push reminding can be provided, and further, when the situation that the recording task is not processed according to the schedule is found, the pushing of corresponding task push execution content to a task attention person (for example, a superior leader of a recording task performer) can be automatically triggered, so that the recording task performer is prompted to process a delayed recording task or replace the recording task performer through the task attention person, and therefore, the on-line task can be continuously pushed, the interruption of task follow-up is not caused, and the normal circulation of the on-line task is ensured. In addition, the time length of the task node and the timing step length can be customized when the task is created, and the flexibility of an automatic task circulation mechanism is guaranteed.
