CN104318684A - Method for self-service submission of invoicing data - Google Patents

Abstract

The invention discloses a method for self-service submission of invoicing data, which is a software design method aiming at dial-up networking of a special embedded network invoicing terminal based on an embedded Linux operating system in the tax industry. The software design method can effectively meet the requirement that the network billing terminal is connected with the network through the universal internet access equipment of the USB interface through the USB interface by the extraction technology, the USB string conversion technology, the PPP dialing technology and the like of the universal internet access equipment of the USB interface when the USB interface equipment is powered on, simultaneously, the plug and play can be realized without distinguishing the model of the internet access equipment, the universal design of the network billing terminal software is effectively solved, and the life cycle of the network billing terminal software is prolonged.

Description

A kind of self-service method of reporting and submitting the data that issue invoice

Technical field

The present invention relates to the equipment manufacturing technology field that the software design approach related to is applicable to based on linux system, a kind of specifically self-service method of reporting and submitting the data that issue invoice.

Background technology

Existing network terminal of making out an invoice realizes online by the network equipment of USB interface, need to carry out customization according to the equipment of different model and drive exploitation, and equipment is shorter as the universal model change cycle, network terminal of making out an invoice is caused to need to change software frequently to meet the network equipment of different model.The life cycle of software shortens, directly cause the exploitation of software, testing cost rising, cause unnecessary human resources to drop into, also cause network make out an invoice terminal maintenance cost raise, therefore a kind of technological means is needed to address this problem, meet network to make out an invoice the general support of terminal for different model equipment for surfing the net, meet the network insertion demand of user.

Summary of the invention

The object of this invention is to provide a kind of self-service method of reporting and submitting the data that issue invoice.Solve network make out an invoice terminal dialing online software, need the problem according to network equipment customized development.

The object of the invention is to realize in the following manner, automatically extract supplier number VID and production code member PID by software, load USB according to the supplier number extracted and production code member and turn serial port drive.After drive load completes, software automatically configures dialing parameters, generates Dial Up script, utilizes pppd program dial-in network operator, and automatic configuration network is made out an invoice the information such as the local ip address of terminal and DNS.

Concrete steps are as follows:

1) embedded Linux system kernel setup, chooses usbserial and ppp module to carry out the recompility of kernel module, is again burnt in network billing machine by kernel module;

2) write USB device descriptor and extract software, enumeration process when powering on according to USB device, the supplier number in extraction equipment descriptor and device numbering;

3) load usbserial module in kernel according to the supplier number extracted and equipment identity, USB device is converted to serial ports Modem equipment;

4) configuration parameters such as the dial user's name title, password and the APN that are inputted by user generate Dial Up script automatically, are stored in network billing machine;

5) detect the state of the USB interface network equipment, automatically or manually call pppd dial-up program, dial in the server of operator;

6), after dial-up success, local gateway, DNS information is automatically configured.

The invention has the beneficial effects as follows: the software design approach that patent of the present invention relates to is applicable to the equipment based on linux system, need the kernel setup USB in linux system to turn string driver module and ppp dial module, USB device descriptor extraction module encapsulates separately.Advantage is: extend the life cycle of software, and the human resources of saving enterprise drop into, and reduces network and to make out an invoice the maintenance cost of terminal.

Embodiment

With reference to Figure of description, the self-service method of the data that issue invoice of reporting and submitting of the present invention is described in detail below.

The software design approach that dials up on the telephone of Patent design of the present invention, being applied to Tax makes out an invoice on terminal based on the dedicated network of built-in Linux, meet the heterogeneous networks access demand of taxpayer's end, make the make out an invoice network insertion of terminal of network be not limited to the restriction of geographic position, network layout, USB interface network equipment product type.

Implementation step is as follows:

1, embedded Linux system kernel setup, chooses usbserial and ppp module to carry out the recompility of kernel module, is again burnt in network billing machine by kernel module;

2, write USB device descriptor and extract software, enumeration process when powering on according to USB device, the supplier number in extraction equipment descriptor and device numbering;

3, load usbserial module in kernel according to the supplier number extracted and equipment identity, USB device is converted to serial ports Modem equipment;

The configuration parameters such as the dial user's name title, password and the APN that 4, are inputted by user generate Dial Up script automatically, are stored in network billing machine;

5, detect the state of the USB interface network equipment, automatically or manually call pppd dial-up program, dial in the server of operator;

6, after dial-up success, the information such as local gateway, DNS is automatically configured.

Except the technical characteristic described in instructions, be the known technology of those skilled in the art.

Claims (1)

1. a self-service method of reporting and submitting the data that issue invoice, is characterized in that concrete steps are as follows:
