教师信息查询模块
信息查询模块与信息修改模块有一些交叉的部分比如说信息查询模块也可以对教师的基本信息进行修改删除等操作,基本方法与修改模块很相似。可以说信息查询模块就是信息修改模块的补充和延伸。但是在在信息查询模块中,查询的能力更加强大,它可以以姓名、入校时间、所学专业、所在基本单位等为关键字进行查询,查询结果也是以黄色长条的形式显示出来。可以说查询修改模块结合起来使用,可以大大提高管理员管理信息的效率,增强系统的可用性。
本系统分为五个功能模块,它们分别是教师信息录入模块、教师信息修改模块、教师信息查询模块、教师信息打印模块。
下面分别介绍各个模块的功能用途,以及使用

电子时钟功能与使用
该电子钟由于使用12MHZ晶振,故而能获得较高精度的时间。它能同时显小时,分钟和秒。设有两个按键:A和B键。A键用于选择要校正的目标,是小时,分钟还是秒,按第一下时,选择秒,按第二下则选分钟,第三下则选小时,第四下则退出校时,第五下又选秒,如此循环,可选择校时或退出校时。B键每按一次,所选对象就会加1,比如,已选择分钟,那么每按一下此键,分钟数目就会加上1。
Electronic clock function and the use of the bell as a result of the use of e-12MHZ crystal, they are able to obtain a higher accuracy of the time. At the same time it can significantly hours, minutes and seconds. There are two buttons: A and B keys. A key is used to select the goal of correction is hours, minutes or seconds, the next by the first, the choice of seconds, according to the election under the second minute, the third hour of the election, has withdrawn from school under the fourth, the fifth another election under the second, and so the cycle of school or may choose to withdraw from school. B button every time, the selected object will be plus 1, for example, have chosen to minutes, then each click on this button will add the number of 1 minute. (2009-06-11, Asm, 56KB, 下载26次)
一个基于51单片机的时钟电路设计源代码
时间以24小时为一个周期;
显示时、分、秒;
有校时功能,可以分别对时及分进行单独校时,使其校正到标准时间;
计时过程具有报时功能,当时间到达整点前5秒进行蜂鸣报时;
为了保证计时的稳定及准确须由晶体振荡器提供表针时间基准信号。
