2008年11月,我国为应对世界金融危机,政府决定投入4万亿元拉动内需,其中有大约40%以上用于城乡电网建设与改造。AWCCA组织由上海电缆研究所所长魏东任首届主席,秘书处设在上海电缆研究所,标志着中国已成为亚洲电线电缆行业的中心。
什么是封锁时间?就是当车辆从厂区内出去时,从光电开关感应到车辆开始,到T2这一时间段内,消毒机不工作,这段时间称之为封锁时间。为了方便说明电路的工作原理,我们来画一下消毒通道、喷雾立柱、感应光电开关的位置等效图,如下图所示。其中小三角代表光电开关,四个小方框代表喷雾立柱。电路的详细工作原理:车辆从大门口进入:光电开关1先感应到车辆,其常开触点闭合,交流接触器KM吸合并自锁,消毒机开始喷雾消毒。因为接触器KM吸合,其常闭触点KM断开,所以光电开关2所在的支路电源被断开,因此中间继电器KA不会吸合,自然也不会影响光电开关1所在的支路。

4069六反相器推荐工作条件电源电压范围3v-15v;输入电压范围0v-VDD工作温度范围:M类-55℃-125℃,E类-40℃-85℃功耗700mw静态电流25摄氏度时<4uA;输出低电平电压0.05V;输出高电平电压VDD-0.05V;输入输出传播时间小于90ns内部结构及管脚序号见下图三。图三CD4069六反相器内部结构及管脚反相器基本概念以及与非门的关系反相器,顾名思义,“反”就是反过来的意思,就是和前一个不一样,“相”就是相位、状态的意思,反相器就是非门电路,也即输入低电平输出就是高电平,或者输入高电平输出就是低电平;这里所说的高低电平是相对的,即高与低之间相对而言,并不是具体的某一个值,比如3v也可能是高电平也可能是低电平。
