Abstract

An automatic lottery generating system based on two dimensional barcode comprises control system, display system, customer terminal and the network connected between them. The control system is made of data base, CPU, monitor, display and customer end, with prizes and lottery rules and customer data in the data base. Monitor configures and monitors the overall control system. The display end and customer end provide all kinds of data release and receiving interface. CPU analyzes the two dimensional barcode data received from customer end for data base access approval and check. It projects the two dimensional barcode opposite to the display system, sending two dimensional barcode to the control system through network and controlled by the control system. The overall lottery process can be run automatically with interest and mystery. With timely release of the lottery process and result, it adds reliability and interactivity between the media and the user.

Description

Automatic lottery system based on two-dimensional bar code
Technical field
The present invention relates to lottery system, particularly a kind of automatic lottery system based on two-dimensional bar code.
Background technology
The bar code that is provided with in commodity packaging is bar code normally, and this bar code has obtained popularizing and being widely used in fields such as industry, commerce, national defence, communications and transportation, banking and insurance business, health care, post and telecommunications and office automation very soon since coming out.But this bar code information capacity is very little, generally can only hold tens numerals, character or special symbols, this has just determined its purposes can only be used for identifying article, description to Item Information then must depend on Computer Database or the network of setting up in advance, so its range of application is restricted.
Yet the two-dimensional bar code new technology then has advantages such as information capacity is big, reliability is high, security and antiforge purpose is strong.Two-dimensional bar code is a kind of succinct and cheap information storage means from essence.Under specific coding rule, 2D bar code technology can be collapsed into geometric figure with data sources such as numeral, writings and images, and decoding equipment according to suitable decoding algorithm, just can be reduced into this figure corresponding raw data after reading this figure.Be different from traditional bar code, two-dimensional bar code is the bar code symbol of expression information on two-dimensional directional, so its memory capacity had tremendous raising than traditional bar code, and thousands of characters can be stored in the bar code symbol of a postmark size.
Traditional sweepstakes need manually-operated, do systematically work in a plurality of programs such as operating personnel must make at lottery ticket, propagate, prize drawing, prize, and its work is uninteresting, dull, and working result is also opaque.In addition, present prize drawing gimmick is tradition relatively, does not have novelty, and is less to the enjoyment that the participator brings.
Summary of the invention
Task of the present invention provides a kind of automatic lottery system based on two-dimensional bar code, and it is more that it has solved traditional sweepstakes manual steps, and it is uninteresting, dull to work, the problem that enjoyment is less.
Technical solution of the present invention is as follows:
A kind of automatic lottery system based on two-dimensional bar code, two-dimensional bar code are a kind of coding techniquess based on optics recognition image, and it comprises control system, display system, user terminal and the network that connects between them;
Described control system is made up of database, central controller, watch-dog, display end and user side, has prize kind, prize drawing rule and user data in the database; Watch-dog is configured and monitors The whole control system, setting prize, quantity, win a prize probability and prize drawing rule; Display end provides the kinds of data release interface, and connects with corresponding transmitter; User side provides kinds of data transmitting-receiving interface, and connects with corresponding transceiver; Central controller is by analyzing the two-dimensional bar code data that receive from user terminal, and accessing database is examined and checked;
Described display system is meant the terminal that has display screen;
Described user terminal is meant the terminal that has camera;
User terminal is shot with video-corder facing to the two-dimensional bar code on the display system, and two-dimensional barcode information is sent to control system by network, after control system is examined and is checked prize drawing information, then issue real-time prize drawing situation if get the winning number in a bond to display system, upgrade the prize drawing content, and send or show the win a prize voucher or the Step Information of receiving the award to user terminal; Described automatic lottery system is provided with the two-dimensional bar code of prize drawing group, and according to the prize drawing result it is carried out real-time update.
Two-dimensional bar code is as a kind of new information stores and transmission technology, has that information storage is big, cost performance is high, a good reliability, security and antiforge purpose strong, data acquisition and advantages such as recognition makes things convenient for.Two-dimensional bar code is easy to make, and cost is lower, super error correction, and the market segment that product is suitable for is more broad.The two-dimensional bar code new technology relates to light, mechanical, electrical and technical field such as printing, information security, sign, has been subjected to the extensive concern of international community.
The present invention is based on the automatic lottery system of two-dimensional bar code, and one group of two-dimensional bar code on the display system has comprised the two-dimensional bar code that has prize.The user is by shooting with video-corder the two-dimensional bar code on the display system, by user terminal two-dimensional barcode information is passed through two-dimensional bar code scanner or network, send control system to, control system is examined two-dimensional barcode information again, if get the winning number in a bond, then, upgrade the prize drawing content, and send or show the win a prize voucher or the Step Information etc. of receiving the award to the user to the display system issue situation of winning a prize in real time.
According to automatic lottery system of the present invention, not only can implement on the internet, and can be in large and small type market, supermarket, shopping center, bustling location, urban district, leisure place etc. locate to implement.Whole prize drawing process can be moved automatically, and its prize, quantity, the probability of winning a prize, prize drawing rule can be set in advance, and can carry out real-time update according to the result that wins a prize to the prize drawing content.Two-dimensional bar code is used in prize drawing, has increased interest and mysteriousness.Prize drawing process and result can announce in real time, increase confidence level.Prize drawing needs the user to take two-dimensional bar code on the ad display screen with mobile phone, has increased interactive between medium and the user thus.
