自从搞完研究生复试之后就一直闲着,在家无所事事。所以打开一年半都没打开的AD16软件,寻思画个板子玩玩。由于在家很长时间发现平时我爸都是很晚才回来,等他回来时天都已经全黑了。他晚上回来先把车子停好熄火之后,一般要用手机上面的手电筒照着才能看清到家门口的路,如果再有一些什么东西要带回家的话,就没有空余的手来拿手机照着路了,所以这样晚上回来有时候很不方便。所以寻思画个板子看能不能解决一下这个问题。就设计一个自动感应的灯,这个灯白天不会亮,当晚上有人或者车子经过院子门口的话,这个在家门口的灯就自动亮起来,经过一段时间之后它就自动熄灭,从而解决晚上回家漆黑不方便开灯的情况,更加方便家里人晚上的出行。</span></span></p>

#e67e23;">发射端</span></strong> 和 <span style="color: #2dc26b;"><strong>接收端</strong></span> 两部分协同工作来完成事件报警。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto

pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8;">      发送端采用了意法半导体的STM32L151C8T6来作为其控制核心,因为考虑到方便安装,所以发送端采用了锂离子供电方式,同时由于锂离子容量有限,所以采用为了这款低功耗的芯片。锂电池输出电压通过电源芯片FP6291达到稳定输出+5v,然后通过常见的ASM1117芯片来降压成+3.3V,完成发送端基本的供电电压。因为发送端的超声波模块采用+5v供电,所以并没有采用直接把锂电池的电压变换成+3.3v的设计。其次发送端采用了TP4056X来作为锂离子电池的充电芯片,其通过搭配一个三脚的红绿发光二极管就可以很方便的指示现在的充电状态,红色即在给锂离子电池充电,绿色即为电池充满了。为了进一步节省发送端的功耗,所以设计了白天让发送端进入停止状态,夜晚才让发送端工作的工作模式。在硬件上面采用了ADC测量光敏电阻和100K电阻的分压大小来分辨现在是到了晚上还是白天。等到了其分压大于1v时就可以认为到了晚上,可以开始工作了。在夜晚,发送端通过超声波模块来测量是否有物体经过,如果有的话,就通过汇承的HC-12传输模块来向接收端发送报警信息。没有的话,就继续采用一秒检测一次的循环来扫描是否有物体靠近,直至天亮。天亮时,光敏电阻的分压会小于1v,于是单片机就进入停止模式,进而节省电量。待又到了光敏电阻的分压大于1v时,单片机又开始工作。就这样的如此循环工作。另外单片机在发送报警信息之时,还会通过另一个ADC来检测电池电压,当电池电压过小,就会在报警信息当中添加上亏电信息,当接收端接收到含有亏电信息的报警时,会启用接收端的蜂鸣器,来示意发送端亏电,记得及时给发送端充电。</p>

这里补充一下发送端进入停止和唤醒的一些细节。发送端会在光敏电阻分压大于1v进入休眠,在设计时并没有考虑用不熟悉的RTC来做唤醒,而是在进入停止模式之前把HC-12的串口发送引脚也就是发送端单片机的串口接收引脚给配置成EXTI中断。这样在接收端收到发送端发来的进入停止模式的信息之后,会等15分钟通过它的HC-12发送一个信息给发送端,这样就可以唤醒发送端,倘若还是白天,发送端还会进入睡眠,接收端15分钟还会再发消息唤醒发送端,如此往复,直到夜晚,发送端不会停止,开始工作为止。</span></p>

style="font-size: 14px;">      本来接收端的PCB是可以做的比较小的,但家里刚好剩下了一个小米手机里面的4000mAH的电池,所以本着能省就省的原则,就干脆用这个电池来当发送端的锂离子电池了,这个4000mAH的电池比较大,所以画出来的PCB也就比较大了,面积估计是接收端的两倍。</span></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8; text-align: left;"><strong><span style="font-size: 24px; color:

  接收端采用HK32F103C8T6作为控制核心,HC-12作为传输媒介的。接收端是放在家门口的,没必要采用锂离子电池的供电方式,所以直接采用家里的220V作为供电方式,通过HI-Link的电源模块把220v转成5v,在和发送端一样的转换成+3.3v。发送端由于采用的是220v,比较高的电压,所以还是有必要再加上一些保护措施的,于是在220v进线端串了一个250v/0.3A的保险丝,再在其后并了一个压敏电阻和安规电容,增加过压保护,同时还通过一个共模电感来抑制干扰噪声,最后才接到电压模块的220v的输入端。接收端接收到发送端发来的报警信息之后,会对信息做一个判断,来决定是否动作继电器、蜂鸣器或者LED灯。所以为了实现前面夜晚有人就亮灯的想法,于是就把继电器的两端并到了家门口灯开关的两端,从而实现这个有人靠近院子门口,家门口就亮灯的想法。</p>

style="line-height: 1.8;"><strong><span style="font-size: 14px;">在这里补充一下HC-12的信息,发送端和接收端之间的通信靠的就是这个模块的功力,这个模块最远可以通信1KM,所以前面项目名字我才加上了远距离的,这个模块和单片之间是通过串口连接的,所以HC-12模块有两个,发送端配一个,接收端也配一个。这个模块可以按照不同的需求来设置成不同的工作模式,是比较好用的模块,但是有时发送数据时可能会有错误,在程序上面要有容错能力。</span></strong></p>

height="258">在画PCB时,我感触最深的是要提前留出方便测量的点。如这个项目里面用到了串口来收发数据,在以后软件调试时肯定出现这样那样的数据收发问题,所以在设计之时,我特意把单片机的串口多画了一个焊盘,也就是单片机的TX和RX引脚各有两个焊盘,一对TX和RX用来连接HC-12,另一对专门用来调试用,这样可以大大方便后面软件调试,节省后期写程序的时间。</p> <h3

normal-bold-2"> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8;">      同样的程序的编写也分为两部分,发送端的主要工作流程通过光敏电阻来分别是白天或者晚上,白天则进入停止模式,夜晚则开始工作。夜晚工作只要是每秒通过超声波来测距,当检测到有物体靠近时,就向接收端发送报警信息。没有则继续测距。在这些主流程之外,ADC的转换是持续工作的,同时为了降低功耗,RCC里面没有启用PLL倍频,系统时钟为HSE,在测量20个光敏电阻的电压的平均值小于阈值时,就让STM32L151C8T6进入停止模式,给HC-12发送AT+SLEEP令其进入睡眠模式,再启用RTC来15min自动唤醒STM32L151C8T6通过这些配置尽可能降低发送端的待机功耗,从而获得最大的工作时间。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8;">      接收端程序相对简单,其只要对接收到的信息做一个简单处理,并动作相应的开关、蜂鸣器就行。另外接收端采用的是HK32F103C8T6,这个芯片和STM32F103C8T6可以互换的,给HK32写程序时,只需要在下载器里面把芯片容量FLASH SIZE换一下,其他统统和STM32通用,我写程序时头文件用的都还是STM32F10x.H。寄存器、库函数什么的统统参考STM32就可以了。</p> <p
