过负荷记录仪器分为单片机数据采集器和微机数据分析记录数据库软件两部分。 仪器具有监视变压器负荷电流（通过改变传感器也可记录最低电压）并自动记录过负荷电流出现的开始时间，最大值和结束时间的功能。当前版本可保存150次的过负荷数据。并可根据需要扩充。pc机软件具有和仪器通信的能力，能够把仪器采集的数据集中保存，并能进行查询，统计等处理。使用本仪器可以定量分析变压器的过负荷情况。 本原码为PC机部分,使用了串口通信和数据库技术 -Overload apparatus records are divided into single-chip data acquisition and data analysis microcomputer database software records in two parts. Surveillance equipment with transformer load current (by changing the sensor can also record the minimum voltage) and automatically recorded the load current emerging start time, maximum and end times of the function. 150 to save the current version of data overload. And in accordance with the need to expand. pc software and equipment with communication capability to the instrument collected data centrally stored, and can query, statistics and other treatment. Use of the device which can be quantitative analysis of transformer overload situation. Primitive machine code for the PC part, the use of the serial communications and d

自己编写的专门针对6122红外编码芯片的红外解码程序,使用定时器+中断,占用CPU时间少,能稳定可靠的解码

密码锁:根据设定好的密码，采用二个按键实现密码的输入功能，当密码输入正确之后，锁就打开，如果输入的三次的密码不正确，就锁定按键3秒钟，同时发现报警声，直到没有按键按下3种后，才打开按键锁定功能；否则在3秒钟内仍有按键按下，就重新锁定按键3秒时间并报警-Password Lock: According to set a good password, the password used to achieve two key input function, when to enter the correct password, the lock will open, if entered incorrect password three times, on the lock button 3 seconds, also found that alarm sound, do not press the button until the three kinds of after the Open button lock function otherwise, there is still a matter of seconds in the 3 button press, on the re-lock button 3 seconds time and alarm
