  • delphi重启

    delphi做的系统强制重启程序。 服务器死机怎么办?用该软件重启。 1.病毒感染:一般表现,起初能够正常运行,某天突然运行速度变慢,工作效率急剧下降,出现频繁的死机。这时首先进行全面查毒、杀毒,以确定机器是否已经感染了病毒。 2.有些软件编程不规范,不能排在第一加载和运行,而要放在最后运行,否则会引起系统管理的混乱。测试版软件在某方面不够稳定,使用后可能会导致系统无法启动,所以最好少用。 3.在内存较小的情况下,运行占用内存较大的应用程序,容易出现死机。建议在运行程序时应及时重启系统。

  • PLC多种液体自动混合

    采用的PLC是西门子S7-200系列,仿真编程软件为STEP7-Micro。在初始状态,容器是空的,各阀门皆关闭,Y1、Y2、Y3灯皆暗和M搅拌机均为OFF,液面传感器L1、L2、L3为关,加热器H为关。若要启动操作,按下启动按钮(I0.0),开始下列操作: (1)Y1、Y2为ON,液体A和B同时注入容器,当液面达到L2时,L2为ON,使Y1、Y2为OFF,Y3为ON,即关闭Y1、Y2阀门,打开液体C的阀门Y3。 (2)液面达到L1时,Y3为OFF,M为ON,即关闭阀门Y3,电动机起动开始搅拌。 (3)经10S搅匀后,M为OFF,停止搅拌,H为ON,加热器开始加热。 4、当混合液体温度达到某一指定值时,T为ON,H为OFF,停止加热,使电磁阀Y4为ON,开始放出混合液体。 (4)当液体高度降为L3后,L3从ON到OFF,再经5S,容器放空,Y4为OFF,开始下一周期。当按下停止按钮后,在当前的混合操作处理完毕后,停止操作,停在初始状态。
