Description
Technical Field
The invention belongs to the technical field of electricians, and particularly relates to an Android system-based electrotechnical manual platform.
Background
On the one hand, the electrical technology is basic professional knowledge which needs to be mastered by teachers, students and scientific workers who are engaged in electrical transmission in colleges and universities, scientific research institutions and industrial and mining enterprises, and needs various technical manuals for reference in learning and research application. However, the paper handbooks are inconvenient to use in many ways, and are inconvenient to find relevant information quickly. And the searching of the webpage takes longer time and the content is not integrated enough.
On the other hand, in recent years, the mobile internet has been rapidly developed, and the mobile intelligent terminal has been widely popularized, especially the mobile phone has the advantages of being convenient to carry and complete in function, so that the mobile intelligent terminal becomes an essential tool in the life of people, not only influences the aspects of people's clothes and residence, but also becomes an important channel for people to acquire information, understand the world and read.
The 2012 China Mobile Internet application report issued by the Internet data center (DCCI) shows that books on the Android platform are ranked the third and account for 11.2%. Therefore, the important influence of book applications, namely reading applications APP, on the mobile user can be seen, and the digital reading based on the mobile terminal is already a non-trivial amount of force. The smart phone realizes the integration of a communication tool and a reading tool, frees people from the fixed space-time reading environment such as paper books and desktop computers, and really realizes the mobile reading anytime and anywhere.
With the increasing popularity and development of mobile devices, the development of related software is more and more favored by programmers. At present, the Android is developed most rapidly in the field of mobile development. Android is a Linux kernel-based platform published by Google corporation specifically developed for mobile devices, using Java as the primary development language. In the early Android release stage, the recommended development tool is Eclipse, but Eclipse can do a lot of things and is not focused enough. In 2015, Google formally promoted a new Android studio tool developed only for mobile phones.
The Android Studio is a brand-new Android development environment based on IntelliJ IDEA, provides an integrated Android development tool for development and debugging, and developers do not need to download SDK and JDK additionally. The method comprises the steps that an app interface is built in Eclipse, the effect is greatly different from that of a real machine, the speed is slow, but the Android Studio interface is very clear in display and very quick to modify; the printed information of the Eclipse is particularly sloppy, and the printed information of the anti-observation Android Studio is much more detailed; after deleting a file in Eclipse, the previous editing record is emptied, even if the file is restored, the file is hard to understand quickly, and how to roll back many previous operations is a problem unless you use a version control tool; the intelligent identification of the Android Studio is a very big highlight. The system can recognize and push only one or two letters in a long and complex character string regardless of the number of separated characters or different case.
Java is an object-oriented programming language, not only absorbs various advantages of C + + language, but also abandons concepts such as multiple inheritance, pointers and the like which are difficult to understand in C + +, so that the Java language has two characteristics of strong function, simplicity and easiness in use. The Java language, which is representative of the static object-oriented programming language, excellently implements object-oriented theory, allowing programmers to perform complex programming in an elegant, mental manner. Java looks much like C + +, but it removes features in C + + that are rarely used by many programmers, removes operator overload (overload) and multi-inheritance features in C + +, and does not use main files, eliminating pre-processing procedures. Since Java has no structure, arrays and strings are objects, no pointers are needed. Java can automatically process the reference and indirect reference of an object, automatic garbage collection is realized, a user does not need to worry about storage management problems, and more time and effort can be spent on research and development.
The SQLite is a lightweight database, is an ACID-compliant relational database management system, is contained in a relatively small C library, is very portable, and can be applied to software environments with various configurations. The design target is embedded, and the embedded type memory is used in a plurality of embedded products at present, the occupied resource is very low, and only a few hundred K of memories are enough in the embedded type equipment. The system can support a mainstream operating system such as Windows/Linux/Unix and the like, can be combined with a plurality of programming languages such as Tcl, C #, PHP, Java and the like, has an ODBC interface, and has a processing speed higher than that of a world-known database management system with two types of sources such as Mysql and PostgreSQL.
Books like apps are diverse in form and very widely used. However, most of them are reading novels and pushing information, and at present, no App is available for the learners of electrotechnics. However, no platform aiming at the electrical technical manual is available in the market for teachers and students and technologists to inquire and use in real time, so that the Android system-based electrical technical manual platform is designed and developed by combining the prior technologies such as Android, Java, SQLite databases and C/S architecture.
