In the specific implementation mode of the invention, the invention provides a radio off-line task scheduling and data downloading method, which comprises site service and central service.
The off-line task execution process comprises the following steps:
the central service generates a central off-line task and stores the task record. And distributing the offline task to a site service, wherein the site service receives the central offline task, generates a corresponding site offline task, stores the task record, and responds to the unique identifier of the site offline task and data download related information, such as a monitoring station IP. The central service receives the response, stores the response information and the corresponding central off-line task information in a record, and prepares for subsequent task scheduling and downloading. And the central service starts a central task state monitoring thread and monitors the state change of the site offline tasks corresponding to all the central offline tasks so as to modify the state of the central offline tasks. And the site service starts a site task state monitoring thread and monitors all site offline tasks. When all the offline tasks are generated, the task state is to be executed. The site task state is shown in fig. 1.
And the site task state monitoring thread searches all task states as site off-line tasks to be executed and suspended and to be scheduled to start execution, searches corresponding receivers according to the task information, and judges whether to execute the tasks according to the receiver state information and the task priority. And modifying the state of the site offline task into the executing state during task execution, and establishing a new file to store the data of the receiver according to the site offline task information, wherein the size of the file is set through configuration. And if the offline task of the high-priority site occupies the offline task of the low-priority site, modifying the state of the offline task of the occupied site to be suspended. The task state is unchanged in other cases.
And the site task state monitoring thread searches whether all the task states are not completed or failed and the site offline task reaching the scheduled end time, executes the stop task, searches whether the site offline task generates a corresponding data file or not according to the task information, and if so, modifies the offline task state to be completed, otherwise, modifies the task state to be failed.
And when the equipment is powered off or the channel connection is lost due to failure, the off-line task state of the station is modified to be suspended. When the site service is restarted, the offline task state of the site is preferentially recovered to be the task in execution.
The central offline task state is the same as the site offline task state. And the execution task state monitoring thread modifies the state of the corresponding central off-line task according to the change of the monitored site off-line task state except the finished state.
When the central service is started, a central off-line task data downloading thread is started, and the thread inquires the state of the central off-line task as an executing task and stores the task into a set. And finding a corresponding site offline task data file path according to the central offline task information and the file storage rule of the scheme, judging whether a new file needs to be downloaded or not according to the number, the size and the file name of the files of the center and the sites, if the site offline task state is finished and all data are downloaded by the central offline task data downloading thread, modifying the central offline task state to be finished, and moving the finished tasks out of the set.
The file storage rules are as follows:
due to different tasks, the difference of the type and the size of the acquired data file can have adverse effects on the return of the subsequent file. Therefore, the scheme designs that paths and file names are generated according to specific rules, and the influence of differences of data types and sizes is shielded, as shown in fig. 2, each offline task generates a data folder, the data folders are named according to unique identifiers of the tasks, the repeated situation of the files is avoided, the data files respectively generate sub-directories according to the year, the month and the day, the file amount in each folder is reduced, the condition that a large number of files are searched in one folder is avoided, and the efficiency of searching a large number of files in one file is low. The file names are named according to the equipment information, the time, the minute, the second and the millisecond of the execution time and the task information, the size of each file is divided into proper sizes according to the configuration so as to be downloaded, each file generates a corresponding index file, and compared with the files, the file names are different only in suffixes. In the method, the file path and the file name can be uniquely associated with the site offline task, the central service obtains the unique identifier of the site offline task through the record associated with the site offline task, the path and the file name of the obtained data file are stored in the set to be downloaded according to the generation rule of the offline data file, and the task data can be downloaded according to the set central service offline data downloading thread.
The adaptive data download management is as follows:
due to bandwidth limitation, when data downloading and monitoring tasks are connected with the same monitoring station IP and executed simultaneously, network congestion may be caused, and executed tasks are affected. It is therefore required that the data download needs to be done when the monitoring station IP is idle, i.e. idle time. Due to the timeliness of the real-time monitoring task, the real-time monitoring task should be preferentially executed. And if a real-time monitoring task starts to be executed by the same monitoring station IP in the downloading process, stopping the data downloading task. And executing the real-time monitoring task and the data downloading task, respectively storing the corresponding monitoring station IPs into a set, and removing the corresponding IPs when the task is finished. And when downloading the off-line data, acquiring the monitoring station IP connected with the FTP according to the task information. It is then determined whether the monitoring station IP exists in both IP sets. The absence of IP represents that idle may be performed. Presence is not performed. And monitoring an IP set of the real-time monitoring task, judging whether the same IP is used for executing data downloading or not every time one IP is newly added, and stopping downloading the task if the same IP is used for executing the data downloading, so that the real-time monitoring task is ensured to be executed smoothly.
By adopting the method for realizing the radio off-line task scheduling and the data downloading, the path and the name of the data file are generated according to the established rule, so that the subsequent program downloading is facilitated. The data downloading of the invention is carried out in the idle time without influencing the real-time checking task.
In this specification, the invention has been described with reference to specific embodiments thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
