Abstract
The invention discloses a gas card reading and writing method and system based on a browser. The invention discloses a gas card reading and writing method and system based on a browser.
Description
Technical Field
The invention relates to the field of XX, in particular to a gas card reading and writing method and system based on a browser.
Background
In the current gas industry, a large number of IC card meter users still exist, the use of gas of the users mainly depends on IC cards, the IC cards are read and written with gas information into the IC cards, then the cards are inserted into the meters, and the gas readings are finally written into the gas meters, so that the gas is normally used. The mainstream of IC card reading and writing currently depends on CS system, such as CS system developed in Java language, and the read/write card operation is realized by calling Dynamic Link Library (DLL), i.e. calling read/write card function provided by manufacturer, mainly in a Java manner. But due to the rise of the internet, the office environment of people increasingly depends on the wide area network, the client environment is simpler and simpler, all system operations can be completed only by a browser, and great convenience is brought to users. Therefore, many systems are gradually being modified from the CS structure to the BS structure. However, in the BS-structured system, there are many restrictions in using physical hardware, and a web page cannot directly call Dynamic Link Library (DLL) driver hardware. In order to solve the problem, special functions can be quickly added to network applications, desktop applications and development tools by embedding plug-ins into browsers, such as based on ActiveX technology, but the ocx control solved by the ActiveX technology can only be used on IEs and cannot be used in chrome and fire foxs, which brings great inconvenience to users. In addition, the BS program can read and write the IC card through the JS technology, for example, the JS-based window. Aiming at all the problems, the patent aims to design a gas card reading and writing method and system based on a browser, so that a user does not need to rely on a specific browser, does not need to use a CS system, and only needs to finish the reading and writing operation of a gas IC card in the browser like using other BS system functions.
