Fish-tank-system
该项目首先是利用单片机对鱼缸的温度进行智能控制。首先通过外部按键对鱼缸所需温度进行设定。温度传感器 DS18B20 采集温度信息在外围的 LCD 上显示出来。其次是利用光电耦合器判断有无鱼饵，若无鱼饵，发出提示，若有鱼饵，则执行自动投食或手动投食功能。(The project first is the use of single-chip microcomputer to control the temperature of the fish tank. First, the temperature of the fish tank is set by the external button. The temperature sensor DS18B20 collects the temperature information to display on the periphery LCD. Followed by using photoelectric coupler to determine whether the bait, if there is no bait, alert, if there is a bait, automatic throw in and throw food or manually cast and functional food.)

110kv
根据设计任务书的要求，本次设计为110kV 变电站电气一次部分初步设计，并绘
制电气主接线图及其他图纸。该变电站设有两台主变压器，站内主接线分为110kV、
35kV 和10kV 三个电压等级。各个电压等级分别采用单母线分段接线、单母线分段带
旁母接线和单母线分段接线(From the guide of engineering design assignment, we have to
design primary power-system of 110kV substation and draw main
electrical one-line diagram and others. There are two main
transformer in the substation in which main electrical connection
can be divided into three voltage grades: 110kV, 35kV with 10kV.It
deposits sectionalized single bus bar scheme, sectionalized single
and transfer bus bar and sectionalized single bus bar scheme per
grade.)
