说明：  小型的商品管理系统，提供商品和供应商的查询、添加、删除、编辑等功能，以及对商品管理系统业务的权限管理。本系统使用链表结构操作数据，提高了数据处理的效率。设计若干类和文件实现，用链表来存储商品的基本信息以及供应商，系统角色信息等。(The small commodity management system provides the query, addition, deletion, editing and other functions of commodities and suppliers, as well as the right management of the business of the commodity management system. The system uses linked list structure to operate data, which improves the efficiency of data processing. Some classes and files are designed to store the basic information of goods and the information of suppliers and system roles.)

An electric meters are used everywhere to calculate the consumption of power. Wireless meter reading technology can save human resources and another feature of this kind of meter is, it improve the accuracy since it works on real time application, enabling management sector to access to data messages within a short period of time and accurately. Due to its wireless communication network, it just not save human and material resources but this property leads to most economical meter in terms of investment. In this paper, power consumed by the consumer is monitored by base stations through wireless network. It aims to reduce the man power for billing since the meter reading is transmitted through ZigBee and at base stations we calculate bill, save records of consumers. The most important part of this project is that we can monitor any fault in meter as well as any tempering which is used to steal the electricity.
