串口温度数据采集并实时显示
串口温度数据采集并实时显示 读串口数据的原理是,只要当有数据向串口发数据来时,计算机就会自动将其数据写到一个特定的缓冲区,我们只要写程序去读那个特定的缓冲区就可以了. 有数据向串口发过来时,程序可以将数据接收到,接收的数据是字符型的,那么将数据转化为数字型的,再将这个数据的大小作为画图的某一个点的纵坐标,横坐标为数据的序号.将这些点用线连起来就是一个曲线图了,这个就是图形显示基本原理. 查看原来的数据的原理也是这样的,不同的地方就是,数据是从文件中来,同样的也是将多个数据分成一个一个的,然后这一个数据的大小就是画图的某一个点的纵坐标,横坐标同样为数据的序号,再将这些点用线连起来就是曲线图. 图形能移动的原理,是我们首先改变的只是数据,图形并没有变,但图形的形式是由这些数据来确定的,当数据发生变化后,我们通过刷新显示区来变化的.(Serial temperature data acquisition and real-time serial data reading the principle is, as long as when a serial data to the data, the computer will automatically writes data to a specific buffer, we can write specific procedures read that the buffer zone would be fine. Serial data to be sent, process data can be received, the receiving of data is the character, then transform data into digital type, and then the size of the data as a drawing of a point Ordinate, the abscissa serial data. these points will be used to link line is a curve, this is the graphic display the basic tenets. View the original data is the same principle, the difference is, the data from the file, the same data also will be divided into a number one, and then this one is the size of the data to draw a certain point )

NetTraffic
VC++流量监控程序，记录选择的接口号，得到接口号为interfaceNumber的接口流量。采用PDH技术对网卡的数据包进行测量，类似360的流量监控工具一样，可以实时观察上网流量的变化，包括上传流量与下载流量。(VC++ traffic monitor, record selection interface number to obtain the interface number of the interface traffic interfaceNumber. Using PDH technology for measuring card packet, similar 360 traffic monitoring tools, real-time observation of changes in Internet traffic, including download and upload traffic flow.)

PMS
本系统模拟一个计算机病员监护系统（Patient Monitoring System, PMS）。该系统随时接受并监视病人的生理信号（脉搏、体温、血压、心电图等），定时记录病人情况以形成患者日志，当某个病人的生理信号超出医生规定的安全范围时向值班护士发出警告信息。当护士需要时还可以要求系统打印出某个指定病人的病情报告。
本系统全部代码采用MFC在Visual Studio .Net环境中编写。患者所有信息保存在Access数据库（PMS.mdb）中。
(A computer simulation of the system Patient Monitoring System (Patient Monitoring System, PMS). The system is ready to accept and monitor the patient s physiological signals (pulse, temperature, blood pressure, ECG, etc.), regularly records the condition of patients to form a log of patients, when a patient s physiological signals beyond the scope of the required safety of doctors to the nurses on duty to issue a warning message . When nurses need also can ask the system print out a report of the designated patient. All the system code using MFC in Visual Studio. Net environments prepared. Patients all the information stored in the Access database (PMS.mdb) in.)
