微型数字键盘的代码-micro-numeric keypad code

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.

电动车从起跑线出发（车体不得超过起跑线），沿引导线到达B点。在“直道区”铺设的白纸下沿引导线埋有1~3块宽度为15cm、长度不等的薄铁片。电动车检测到薄铁片时需立即发出声光指示信息，并实时存储、显示在“直道区”检测到的薄铁片数目。 （2）电动车到达B点以后进入“弯道区”，沿圆弧引导线到达C点（也可脱离圆弧引导线到达C点）。C点下埋有边长为15cm的正方形薄铁片，要求电动车到达C点检测到薄铁片后在C点处停车5秒，停车期间发出断续的声光信息。 （3）电动车在光源的引导下，通过障碍区进入停车区并到达车库。电动车必须在两个障碍物之间通过且不得与其接触。 （4）电动车完成上述任务后应立即停车，但全程行驶时间不能大于90秒，行驶时间达到90秒时必须立即自动停车。 -err

在基于脉冲的UWB系统中，采用瑞克接收机合并多径信号能量并进行相干检测，信道估计问题即估计多径信号的到达时间和幅度。在基于OFDM的UWB系统中，接收机根据信道频域响应对每个子信道进行频域均衡后进行相干检测，信道估计问题即估计信道频域响应。-Pulse-based UWB systems, rake receivers using the combined multipath signal energy and coherent detection, channel estimation problem that is estimated multipath signal arrival time and amplitude. OFDM-based UWB system, the receiver under the channel frequency response of each subchannel to frequency domain equalization after coherent detection, channel estimation problem that is estimated channel frequency response.
