C#写得超市监控

 

本实例实现超市摄像头定时监控系统。运行本例后，在“定时监控设置”处设置监控的星期及时间，单击【保存】按钮，将“定时设置”参数数据保存到数据库中。系统在运行到定时时间后，程序将自动进行监控。如图所示。另外，监控的录像文件和图片文件保存在D盘根目录中，命名格式为系统当前日期。

实现过程

（1）新建一个项目，命名为Ex13_10，默认窗体为Form1，添加一个类文件（.CS），用于编写视频类。

（2）在Form1窗体中，主要添加一个PictrueBox控件，用于显示视频。

（3）主要程序代码。

视频类中主要程序代码如下：

        ///   <summary>  

        ///   开始录像

        ///   </summary>  

        ///   <param   name="path">要保存录像的路径</param>  

        public void StarKinescope(string path)

        {

            IntPtr hBmp = Marshal.StringToHGlobalAnsi(path);

            SendMessage(hWndC,WM_CAP_FILE_SET_CAPTURE_FILEA,0, hBmp.ToInt32());

            SendMessage(hWndC, WM_CAP_SEQUENCE, 0, 0);

        }

        /// <summary>

        /// 停止录像

        /// </summary>

        public void StopKinescope()

        {

            SendMessage(hWndC, WM_CAP_STOP, 0, 0);

        }

       Form1窗体主要代码如下：

        private void timer1_Tick(object sender, EventArgs e)

        {

            string strTime="";

            //星期一

            if (chk1.Checked && Convert.ToInt32(DateTime.Now.DayOfWeek)==1)

            {

                strTime = DateTime.Now.ToString("HH:mm");

                DateTime date = Convert.ToDateTime(mtxt1.Text);

                if (strTime == date.ToString("HH:mm"))

                    video.StarKinescope(@"d:/" + DateTime.Today.Month.ToString() + DateTime.Today.Day.ToString() + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + DateTime.Now.Second.ToString() + ".avi");

            }

            //星期二

            if (chk1.Checked && Convert.ToInt32(DateTime.Now.DayOfWeek) == 2)

            {

                strTime = DateTime.Now.ToString("HH:mm");

                DateTime date = Convert.ToDateTime(mtxt2.Text);

                if (strTime == date.ToString("HH:mm"))

                    video.StarKinescope(@"d:/" + DateTime.Today.Month.ToString() + DateTime.Today.Day.ToString() + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + DateTime.Now.Second.ToString() + ".avi");

            }

            //星期三

            if (chk1.Checked && Convert.ToInt32(DateTime.Now.DayOfWeek) == 3)

            {

                strTime = DateTime.Now.ToString("HH:mm");

                DateTime date = Convert.ToDateTime(mtxt3.Text);

                if (strTime == date.ToString("HH:mm"))

                    video.StarKinescope(@"d:/" + DateTime.Today.Month.ToString() + DateTime.Today.Day.ToString() + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + DateTime.Now.Second.ToString() + ".avi");

            }

            //星期四

            if (chk1.Checked && Convert.ToInt32(DateTime.Now.DayOfWeek) == 4)

            {

                strTime = DateTime.Now.ToString("HH:mm");

                DateTime date = Convert.ToDateTime(mtxt4.Text);

                if (strTime == date.ToString("HH:mm"))

                    video.StarKinescope(@"d:/" + DateTime.Today.Month.ToString() + DateTime.Today.Day.ToString() + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + DateTime.Now.Second.ToString() + ".avi");

            }

            //星期五

            if (chk1.Checked && Convert.ToInt32(DateTime.Now.DayOfWeek) == 5)

            {

                strTime = DateTime.Now.ToString("HH:mm");

                DateTime date = Convert.ToDateTime(mtxt5.Text);

                if (strTime == date.ToString("HH:mm"))

                    video.StarKinescope(@"d:/" + DateTime.Today.Month.ToString() + DateTime.Today.Day.ToString() + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + DateTime.Now.Second.ToString() + ".avi");

            }

            //星期六

            if (chk1.Checked && Convert.ToInt32(DateTime.Now.DayOfWeek) == 6)

            {

                strTime = DateTime.Now.ToString("HH:mm");

                DateTime date = Convert.ToDateTime(mtxt6.Text);

                if (strTime == date.ToString("HH:mm"))

                    video.StarKinescope(@"d:/" + DateTime.Today.Month.ToString() + DateTime.Today.Day.ToString() + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + DateTime.Now.Second.ToString() + ".avi");

            }

            //星期日

            if (chk1.Checked && Convert.ToInt32(DateTime.Now.DayOfWeek) == 7)

            {

                strTime = DateTime.Now.ToString("HH:mm");

                DateTime date = Convert.ToDateTime(mtxt7.Text);

                if (strTime == date.ToString("HH:mm"))

                    video.StarKinescope(@"d:/" + DateTime.Today.Month.ToString() + DateTime.Today.Day.ToString() + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + DateTime.Now.Second.ToString() + ".avi");

            }
