Background of the project:
Along with the development of domestic lottery industry, all kinds of lottery, such as welfare lottery, sports lottery, etc, are issued throughout the country. However, different application environments and laggard operating systems have blocked the development of lottery industry, that is, release sites of lottery distribute all over the country, which leads to the differences in application environment, meanwhile, most operating systems adopt DOS, which is difficult to use and has an incomplete network connection function.

Shenzhen SinoData Tech Co., Ltd. (SINODATA), an Associate Member of World Lottery Association, is a hi-tech enterprise founded in 1998. Being the leading total solution provider in China's lottery industry, SINODATA is now occupying the largest market share and highest business revenues and is regarded as the most powerful and trustworthy lottery company in China.

The Red Flag Company cooperates with SINODATA in developing embedded system of lottery machines, and based on this, computer lottery machines have been successfully developed and put into use in the nationwide, becoming the most widely used terminals in China's lottery market.

Customer requirements:
The system must be safe and stable, and meanwhile, has efficient and secure network communication function, data protection function in abnormal circumstances, as well as user-friendly interface. Considering the project's importance, the company which has professional experience in Linux must be chosen to realize the whole plan of research and development.

Solutions and deployment:
The embedded system of Red Flag has the following features:

First, the ControLinux, contrasting with traditional operating systems, has perfect network connection function and supports the TCP/IP protocol, the PPP agreement, etc.

Second, the special operating system of lottery machine adopts document management mode for external devices of network, which is convenient for usage and management.

Third, for achieving the excellent performance of power-off protection and aiming at the characteristics of EXT2, the system is customized, which can protect the system's data and greatly reduce the data loss caused by abnormal shutdown.

Fourth, the users can adopt the synchronous way to operate when writing the application programs in order to ensure the data safety.

Fifth, the power-off protection performance of hard disk can provide the system with reliable data protection capacity, which can safeguard the lottery betting smoothly.

Products of software and hardware:
In order to meet the customers' requirements, through enhancing the safety performance of the file system which is based on Red Flag ControLinux, the customized system supported by GUI graphic system is greatly improved.

In order to satisfy the requirement of high safety, industrial control panel with serial, parallel, Ethernet card, etc, must be chosen, meanwhile, the external equipments should be easy to expand which could shorten the hardware’s design cycle.

Effects evaluations:
The embedded system provided by Red Flag Company has fully satisfied the users' requirements in usability, security and stability. The lottery machines produced by SINODATA have been put into use in many provinces including shandong, liaoning, hunan, hainan, jiangsu, jilin, shanxi, anhui, guizhou, jiangxi, yunnan, etc, becoming the most popular terminals in China's computer lottery market.
