1) 8路数据采集功能 通过调节可变电阻实现0-5V的电压输出作为8路输入信号使用,每路信号用2位LED显示采集的结果。报警:任意一路超过某一门限(可自己设定)时,发出报警(声音+灯闪烁,并通过灯指示是哪一路报警),同时停止采集。 2) 计数功能 利用计数功能键,实现每按一次按键,LED显示加1,从0-99计数。 3) 秒表功能 只用一个键控制。按下一个按键后时钟启动,从零开始计时,计时间隔0.01秒,再按一次后停止。再按一次后清零。如此循环。 -3 function keys set up: When a function key is pressed after entering the corresponding functional model. Three features are: 1) 8-Channel Data Acquisition function by adjusting the variable resistor to achieve the 0-5V voltage output 8-channel input signal as the use of signals each with two LED display of the results collected. Alarm: any way above a certain threshold (which can be set), the issue of police (voice+ lights flicker, and through which light is the way the police instructions), at the same time to stop collecting. 2) counting function count function keys to use to achieve every time button, LED display plus 1, counting from 0-99. 3) with a stopwatch function keys control only. After pressing a button to start the clock, to start from scratch time, time interval 0.01 seconds, and then after a stop. And then once cleared. Such a cycle.

1:读取输入P1.0口的电压值,由于硬件实现了将5V以上的电压转换为三分之一的输入定呀, 由于电动车单个蓄电池最高电压为12v,经过运放电路,输入到P1.0口的电压值最高是4V 2:当读取到的电压小于3V,声光报警电路接通并报警。 3:P1.3口具有高低捕获功能,本程序设定是下降沿触发。 将捕获到的数字经过转换后送到数码管显示。 4:数码管是4位带小数点共阳数码管。用于显示转速大小。转速单位是Km/h。 一般电动车最高时速不超过100Km/h,所以数码管前两位显示整数部分, 后两位显示小数部分。 5: 加入了按键切换里程与速度功能。定义P1.1口为按键功能-1: P1.0 port read input voltage value, due to the hardware implementation of the above 5V input voltage into a third set Yeah, because a single battery electric vehicle for the maximum voltage 12v, through the op-amp circuit, the input to the P1.0 mouth highest voltage value is 4V 2: When reading the voltage is less than 3V, sound and light alarm circuit is turned on and the police. 3: P1.3 port has a low capture feature, the program is set to trigger on the falling edge. The captured after the conversion to digital LED display. 4: Digital tube with a decimal point is four common anode digital. Size used to display speed. Speed unit is Km/h. General electric car a top speed of no more than 100Km/h, so the first two digital tube display the integer part, fractional part of the two displays. 5: adding buttons to switch mileage and speed capabilities. P1.1 port is defined function keys

DS18B20
DL : 0
本温度计属于多功能温度计,可以设置上下报警温度,当温度不在设置范围内时,可以报警。 数字温度计所测量的温度采用数字显示,控制器使用单片机89S51,测温传感器使用DS18B20,用3位共阳极LED数码管以串口传送数据,实现温度显示。-The use of digital temperature sensor DS18B20 temperature measurement signal, after calculations show the corresponding temperature value on the LED digital tube. A temperature measurement range of 1 to 99 degrees. The thermometers are versatile thermometer, you can set the upper and lower temperature alarm when the temperature is not set range, can call the police. Digital thermometer to measure the temperature with digital display controller using microcontroller 89S51, temperature sensor DS18B20, with three common anode LED digital serial transmission of data in order to achieve temperature display. Can easily be read directly measured temperature value from the temperature sensor DS18B20, convert that to meet the design requirements.
