Description of drawings
Fig. 1 and Fig. 2 are the method flow diagram of the dynamic refresh data of an embodiment;
Fig. 3 is that the schematic diagram that reads and writes data is divided and controlled to region of memory.
Embodiment
As depicted in figs. 1 and 2, be the method flow diagram of the dynamic refresh data of an embodiment.The method is based on function call and the internal memory switching technology of unified interface, and implementation process is not subjected to interruptedly to read the purpose of amended configuration file, reaches the effect that configuration is come into force immediately.As shown in Figure 3, the method is divided the first data field and the second data field that is used for the storage data in internal memory, and adopt the Memory control switch to control toward the first data field or data (being save data) are write in the second data field, perhaps from the first data field or the second data field read data.The first data field and the second data field be the preliminary data district each other.
The method comprises the steps:
S110: operation initialization thread.Call initialization interface during program start, carry out the initialization data operation.
Initialization thread is mainly carried out following steps.
Step S111: the objective function that foundation need to be refreshed and the incidence relation of event, described event is triggered by operation.In event driven program, at first need with the objective function registration objective function that i.e. foundation need to be refreshed and the incidence relation of event (perhaps adding the processing function corresponding with this event).The operation of trigger event comprises the operation of modification equipment or software configuration etc.When event is triggered, processes accordingly function (objective function) and be called, to complete corresponding function.In one embodiment, utilize function pointer registration objective function.
In addition, when initialization, also comprise:
Step S113: the Memory control switch is placed in the first state or the second state.This step is used to specify the region of memory of the data preservation that next time loads.
Step S115: the data with acquiescence are carried out refresh operation.Want refresh data, at first need to load data in internal memory, this step depends on step S140, if load the data manipulation success in step S140, and execution in step S117, otherwise stop.
Step S117: the Memory control switch is placed in second state or first state relative with the first state or the second state.After data loaded successfully, after also namely being read into internal memory corresponding data district, business software can come refresh data by unified calling interface.Then the Memory control switch is placed in opposite state, when also being next Event triggered, data is loaded into another data field in two data fields of internal memory.
As a rule, have the main data area of an acquiescence in system, another is the preliminary data district.For example in the present embodiment, the first data field is the main data area, and the second data field is the preliminary data district.When program initialization, the data acquiescence is loaded into the main data area, so also the Memory control switch is placed in the first state in step S113, can read be used to the data that refresh from the first data field as the main data area thereby make when refresh data.Afterwards, the state of Memory control switch is set to the second state.For example, in one embodiment, during initialization, the state of Memory control switch is set to FALSE, then loads and refresh data.If successfully load, the state with the Memory control switch after loading is completed so is set to TRUE.
After the initialization of step S110 is completed, namely begin step S120: run case scanning thread.The event scanning thread is used for the event that monitoring system produces, the processing of the line correlation of going forward side by side.Mainly comprise:
Step S121: detect the event that whether is untreated in list of thing.If, execution in step S123, otherwise return to step S121 after execution in step S125.When the needs refresh data, the executing data refresh operation, trigger event, when different operations constantly produces, will trigger a plurality of events then.A plurality of events were kept in list of thing successively according to the triggered time.If there is the event that is untreated in list of thing, representative has the operation of refresh data, and need to process this moment to this event.This step realizes monitoring by the mode of cycle detection.
Step S123: select one of them event according to selection strategy, arrange refresh be designated true.The selection strategy of the present embodiment is First come first served (FIFO), and event was numbered successively from small to large according to the time that arrives, and all selects the minimum event of numbering at every turn.
Step S125: arrange to refresh and be designated vacation.
The above-mentioned sign that refreshes is used for informing that data load thread whether Event triggered is arranged, thereby determines whether to load data.Through step S121 ~ S125, event scanning thread output valve is the sign that refreshes of true or false.
Step S130: service data refreshes thread.This step is used for carrying out the operation of refresh data.Comprise the steps:
Step S131: whether detection refreshes sign is true.If, execution in step S140, otherwise execution in step S133 and return to step S131.Be designated true time when refreshing, execution in step S140 processes event.Otherwise whether circulation execution detection refreshes sign is genuine step.
Step S133: sleep Preset Time.In the present embodiment, Preset Time is preferably 10 milliseconds.
Simultaneously, in the Refresh Data thread, go back execution in step S135: whether the operation that loads data in detecting step S140 is successful.If, execution in step S137, otherwise return to step S131.
Step S137: with the state negate of Memory control switch.Also namely become the second state from the first state, perhaps become the first state from the second state.After each Event triggered and data load successfully, with the state negate of Memory control switch, data are loaded into another data field when specifying next time Event triggered.
Step S130 also generates the result of event handling according to the execution result of step S140.
The result of this event handling is also read by event scanning thread (step S120), and carries out following steps.
Step S127: whether decision event finishes dealing with.If, execution in step S129, otherwise return to execution in step S127.
Step S129: update event list.The state of the event of having finished dealing with is changed to process.So far, processed the completing of event, refresh operation is performed simultaneously.If also have other event in list of thing, repeat the above-mentioned step process next event that begins from step S121.
Step S140: service data loads thread.Comprise:
Step S141: the state that detects the Memory control switch.If the state of Memory control switch is the first state, execution in step S143, if the state of Memory control switch is the second state, execution in step S145.
Step S143: call the objective function of all opening relationships, load data, and store data in the first data field.With the first data field operational objective function in internal memory, executing data refresh operation.
Step S145: call the objective function of all opening relationships, load data, and store data in the second data field.With the second data field operational objective function in internal memory, executing data refresh operation.
Step S147: return to execution result.
The data that load according to the event that triggers related in the present embodiment method are configuration file, are used for the configuration of real-time change equipment or business software.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
