预收费煤气表的设计
摘要:目前使用的机械式煤气表存在较大的弊端,给管理部门和用户带来了很大的不方便,为了能从根本上解决此问题,设计一种新型的智能煤气表收费系统就显得十分必要。针对这种情况,本文设计了智能IC卡煤气表系统,以实现煤气收费管理的电子化和信息化。
本设计是基于AT89S52单片机控制的煤气计费模块,控制简单,设计中采用非接触式智能卡模块实现预付费功能,具有严谨的保护和防作弊功能;系统具备液晶显示功能,利用RT1602液晶显示模块显示余额、用气量等数据;为了保证系统的稳定性和可靠性,该设计中还加入了掉电保护模块,保护用户数据不丢失,使计费系统实现自动化和最优化。

毕业设计报告(论文)摘要
(Thesis) Title: YuShouFei MeiQiBiao design
The mechanical gas meter at present has a big disadvantages to the management and the users a great deal of inconvenience. In order to fundamentally solve this problem, it is very necessary to design a new type system of intelligent gas meter. In view of this situation, this paper designed an intelligent IC card gas meter systems in order to achieve the gas tariffs and the management of electronic information.
The design is a gas billing module which based on the MCU AT89S52, the control is simple, the design take the non-contact less smart card module to achieve pre-paid functions, with have strict protection and anti-cheat functions. System use the RT1602-liquid crystal display function to show the Balance data etc. In order to ensure system stability and reliability, the design also joined the power-down protection module to protect the user data is not lost, make the system enables automated billing system and optimization.
Keywords: Gas meter, Non-contact card, Prepaid, Single-chip
