30、完成各种测量任务并且以相当的速度显示测量结果。然而,为了确定测量值的重要性,测量者必须很快地读取和理解测量值,即在头脑里将测量值与预设标准进行对照,并以此采取相关行动。因此,当这些预设标准不确定的时候,这个任务将会变得非常复杂。关于发明的总结因此,这个发明的主要目标是提供一个改良的数字测量设备,使快速识别所测量值的意义变得容易。这个发明的另一个目标是提供一个数字测量设备,这种数字测量设备使用一种可变色显示器,这种显示器有整快的可变色背景区。总的来说,这种数字测量装置的发明包括一个显示器,而所需要测量的电压的数值则通过一种字符的形式来显示。这个显示器是被一个变色背景区包围的,当测量值被确定时,与
31、其意义相对应的颜色就会亮起。本发明的其他目标将从附属的图纸和描述进行进一步说明。图纸的简要说明这些图纸都是这个发明的首选设备。图1是一个使用可变色背景技术的数字电压表的立体图。图2是可变色数字电压表与模拟比较器的立体图。图3是可变色数字电压表与数字比较器的立体图。图4是数字电压表的简化示意图。图5是在显示屏上测量结果显示在绿色背景里的黄色数字的详情。图6是在显示屏上测量结果显示在蓝色背景里的黄色数字的类似细节。图7是在显示屏上测量结果显示在黄色背景里的红色数字的类似细节。图8是可变色显示设备中一个元件的简化示意图。首选设备的描述谈到现在,更特别是,在图1显示了使用一个可变色显示器的数字电压表的
32、立体图,显示器的四周是可变色背景区域。数字式电压表中,包括了一个A/D(模拟到数字)转换器,见51,将输入的模拟信号转化为数字信号,并显示解码器(见23)将数字数据以字符形式显示在一个可变色显示屏上,见11。随后将更加具体地指出,显示器(11)包括了可变色显色区域的排列模式和整体的可变色背景区。本发明增加了一个区分颜色控制系统(21)和背景颜色控制系统(22),区分颜色控制系统控制亮起适当的颜色在数值的显示区,背景颜色控制系统管理测量值的背景颜色。本发明的数字电压表可以同时通过字符形式显示测量值,通过颜色的背景显示测量值的意义。通过一个例子,测量值被认为是正常的,可显示在绿色背景,实测值略有些
33、反常的可显示在蓝色的背景,测量值在临界状态可能被显示在红色背景。图2显示了用模拟比较器81来描绘数字电压表特性的框图。模拟比较器81的输入耦合到的A/D转换器51的输入,比较输入信号与预定的范围并以此制定相应的信号。背景颜色控制器22根据相应的信号来显示背景面积。图3显示了被数字比较器84来描绘特点的数字电压表图。该转换器84输入耦合到A/D转换器51的输出,来比较输出数据与预先确定的范围并以制定相应的信号。背景颜色控制22表明背景区域的范围是根据相应信号来显示的。图4是表现出了本发明电压表的一个数字示意图,其中包括一个数字电压表芯片53,它是用来测量输入信号输入电压的,通过一个电阻90A和去
34、耦电容93A,确定其是高点平还是低电平输入。电阻90B型和电容器93B,加上输入振荡器,提供选择一个合适的内部振荡器频率。自动零电容93C是用来减少噪音的。积分电容93D和缓冲电阻90C提供所需的电压振幅和线性。显示屏41第一个显示元件由一个数字1和减号组成。在第二个元素里,段被指定为第31A,31B,31C,31D,31E,31F和31G,每个显示元素有三种颜色R(红色),G(绿色)和B(蓝色)控制输入的指定显示终端机。每个显示部位都被可变颜色的背景所包围,这将在其后更加明确地指出。每个显示元素的背景区也有三色控制输入的R,G,和B返回指定。这个从所显示的内容和背景颜色控制领域都是分别互联的
35、,形成控制所有显示元素颜色的一致显示都是R,G和B。背景的颜色显示也是R,G和B,用于整个背景面积32色彩的均匀控制。图5到7显示的是测量值的例子,规定下限和上限在范围15到15(在伏特或任何其他合适的单位)。本发明是在颜色控制背景区32中表明测量值指示是否在上限和下限的范围内是否高了最上限或低于下限。图5是在绿色显示屏上显示了一个测量值为1234的值来表明它实在下限和上限范围内。图6在蓝色背景区显示了数值1789,以表明它低于最低限制。图7是在红色背景区显示了数值1965,以表示高于上限。为了这些图的说明不那么复杂,所有测量值显示都显示黄色。这会被意识到这个颜色也可能会发生变化,接下来会做进
36、一步介绍。从图57所示描述的显示测量值方法的优越性是显而易见的。这些都被背景区32完全包围,所有的41个显示单元与此都是明显相关的。十分清楚的是,背景区域的颜色只涉及到在显示屏上展示其境内部分的值,而不显示位于边界之外的值。图8是表现出了一个字符的7段变色与变色背景显示简单化示意图。每个背景区域都包括一个紧邻显示部分的三个LED区域红色LED1,绿色LED2,和蓝色LED3,这都是为了调整一个可变颜色的复合光信号。为了方便说明,这些LED被指定为部分字母,例如,在B节段的红色LED被显示为1B,在D段的绿色LED被显示为2D,在这部分的蓝色LED被显示为3F。背景区域是由背景区域相邻的显示段组
37、成。每个背景区域包括一个紧邻LED红色发光二极管LED4,适合产生符合灯光信号变换颜色的LED5和LED6。尽可能多的在背景区域的LED被指定为显示段相邻的字母。本发明可现在简单总结该方法同时披露显示测量值及意义,展示手段上所包围面积变色背景造成测量值将在显示屏上显示。字符格式和通过控制区域的背景颜色是指按照测量值的意义来决定的。数字电压表透露,包括用于生产在字符显示的数字数据格式和数字数据的输入信号成比例,显示了模拟到数字转换器和一个可变面积大幅周围背景的颜色显示。比较器提供了讯问相应的发展比较信号的输入信号的价值意义。所有在附图中被描述和图解说明的问题,都应该通过数据图表去理解,而不是在一个狭隘的认知下被理解。显而易见,如果没有从这项发明的原由出发,因为其他一些额外的要求,许多首选设备的解释是可以被修改的。可以设想,该发明的原理也可以适用于许多不同类型的显示设备上,例如有液晶,等离子装置等。
