《多按键处理程序 》，适用于工控按键处理

应用背景 程序可以根据让用户自定义输入生成随机点数量、设定X范围、设定Y范围、设定Z范围来自定义生成一系列随机点数量，并根据用户设定的周围搜索点数量来进行规则格网的插值，然后根据输入的等高线间距进行等高线的生成。 关键技术在图层显示上，可以显示DEM数据、随机点数据、等高线数据，并根据用户自定义的图层进行显示和叠加。程序可以修改等高距进行显示。

片机电子钟的计时脉冲基准是由外部晶振的频率经过12分频后提供，采用内部的定时/计数器来实现计时功能。所以，外接晶振频率精确度直接影响电子钟计时的准确性。 -Machine electronic time clock pulse baseline is by an external crystal oscillator frequency, after 12 minutes after the frequency, using an internal timer/counter to achieve the timing function. Therefore, the external crystal frequency accuracy of a direct impact on the accuracy of the electronic time clock.

装置的功能是对温度进行实时监测与控制。由温度传感器DS18B20对温度进行采样和转换成数字信号送入单片机，并与设定的报警温度上、下限值进行比较，信息通过LCD显示出来。如实时温度超过设定的上、下限值，一方面由LCD显示信息，并发出警报声；另一方面自动控制继电器（Relay）开接通或断开，从而控制加热源的开与断，达到对温度进行实时控制的目的。-Device" s function is real-time temperature monitoring and control. Temperature by the temperature sensor DS18B20 sample and converted into a digital signal into the microcontroller, and with the set alarm temperature of the upper and lower limit comparison information through the LCD display. Such as real-time temperature exceeds a set upper and lower limits on the one hand by the LCD to display information, and the alarm sound the other hand, automatic control relay (Relay) to open turn on or off to control the opening and the heat source off, to achieve real-time temperature control.
