本方案主要是从技术角度，针对工厂的具体环境，说明工程要完成两个子系统：考勤、消费的实现。

考虑到局域网已经全面覆盖了工厂，而基于TCP/IP通信方式的设备具有诸多优势，比如速度快、安装灵活、维护方便等，这都是基于传统的RS485通信方式的设备不具备的优点。在方案中全面采用基于TCP/IP通信方式的考勤机和消费机等设备。

-The program is mainly from a technical point of view, for the plant specific environment, explaining the project to complete the two subsystems: attendance, consumption achieved. Taking into account the local area network has been fully covered by the factory, but based on the TCP/IP communication device has many advantages, such as speed, installation flexibility and easy maintenance, etc., which are based on the traditional means of communication RS485 device does not have advantages. Fully in the program based on TCP/IP communications attendance machines and consumer machines and other equipment.
