The scheduling master station system equipment patrol tasks comprise daily patrol tasks of every day, every week and the like and special patrol tasks issued in special periods. The system designs through the database during the design, formulates the task template and carries out regularization processing on the task template, namely, a user can customize the periodic frequency of the task template for copying and generating the task and the time for finishing the periodic frequency. The task templates under each activation state are completed by regularly calling a storage process compiled in the operation through a background SQL SERVER database, and a task generation function of a generation condition is met, so that the complexity of patrol task management work is reduced;
the implementation scheme is as follows: based on the Quartz framework, Quartz is an open source job scheduling framework that is written entirely in Java and designed for use in J2SE and J2EE applications. It provides great flexibility without sacrificing simplicity, and can be used to create simple or complex schedules for executing a job. It has many features, such as: database support, clustering, plug-in, EJB job pre-construction, JavaMail, support crol-like expression and the like. In a Web environment, Quartz can complete a background job scheduling experience through a configuration file. At the heart of the Quartz framework is a scheduler, which is responsible for managing the environment settings at which the Quartz application runs. To ensure scalability, Quartz employs a multithreading-based architecture that initializes a set of worker threads upon startup, which is used by a scheduler to execute a predetermined job, which is the principle that Quartz can run multiple jobs concurrently. Quartz relies on a set of loosely coupled thread pool management components to manage thread contexts. The Quartz framework has a rich feature set, mainly comprising: 1) a listener. The Quartz frame comprises a scheduler monitor, a job and a trigger monitor, and the implementation conditions of job scheduling and operation can be acquired through the monitors; 2) and (5) customizing the operation. Quartz provides a Job making mechanism, and can conveniently combine a plurality of business processes into a Job work task according to a required execution sequence; 3) the timing is flexible. Quartz supports cron-like expressions, so that the running time of tasks can be conveniently set; 4) and (4) clustering the application. Quartz applications can be clustered to enhance load balancing and scalability of the system.
The main thing to use CronTrigger is to master Cron expression. The Cron expression contains 6 essential components and one optional component, as shown in the following table:

Meanwhile, a calendar management function is added, so that dates (such as weekends, legal festivals and holidays) which do not need to be patrolled can be conveniently and flexibly defined. The method comprises the steps that a manager formulates a task template according to actual requirements, wherein the content of the task template comprises a task type and a name, start and end dates, an execution period and a patrol range (information of a transformer substation, equipment types, component types and the like), and after creation is completed, the template is activated, and a system automatically generates a patrol task according to the period.
3) Data synchronization management: according to the characteristics of the scheduling center network use rule, frequent data synchronization, more ledger photo information and the like, a scheme for uploading and downloading data by using a transfer file copying mode is designed. The scheme can realize the rapid uploading of data to downloading and off-line operation, and reduces the dependence and investment on the network;

The purpose of SyncML development is to provide interoperability for end users, device developers, service providers, and application developers so that any device can access any network data at any time and place. To reduce the traffic transmitted over the network, it can also be written in binary morphs, WBXML.
The SQLite is a lightweight database and an open-source embedded relational database, reduces the overhead of application program management data, has portability, is easy to use, is efficient and reliable, and is designed to be applied to embedded products to provide ODBC interfaces. The mobile terminal used by the inspection system is based on an Android system, and the database is SQLite.
Currently, in terms of data Synchronization of a mobile terminal, SyncML (Synchronization Markup Language, a platform-independent information Synchronization standard protocol) is developed in order to break the restrictions of a network, a platform, and the like. The system is a platform-independent information synchronization protocol established by international major companies, and aims to perform open and industry-wide universal remote data and personal information synchronization among a plurality of networks, platforms and equipment.
