Arduino协助搭建家庭服务器，监控功耗及温度
本帖最后由 softice 于 2017-10-20 00:35 编辑起因
作为一名业余的职业码农，家里需要一台服务器，大内存，低功耗，高可用。
网上搜索了很久也没有找到合适的，所以自己动手丰衣足食。
HP的迷之粉丝于是买了一块服务器主板，却没有机箱风扇接口，所以只能依靠其他的芯片给他管理风扇了。
Arduino是个好选择，省电又方便，而且正好赶上大赛，很幸运哈哈哈~
成果
先上成品~ 就是长这个样子：

设计
做一个东西以前，时刻要求自己记得以下的设计十诫，不然容易对不起付出的时间和精力。所以一一核实一下先：
好的设计是创新的 Good design is innovative.
好的设计创造好用的产品 Good design makes a product useful.
好的设计是符合审美的 Good design is aesthetic.
好的设计帮助我们理解产品 Good design helps us to understand a product.
好的设计是含蓄的 Good design is unobtrusive
好的设计是坦诚的 Good design is honest.
好的设计是耐用的 Good design is durable.
好的设计由最终的细节决定 Good design is consequent to the last detail.
好的设计关注环境 Good design is concerned with the environment.
好的设计是“没有”设计 Good design is as little design as possible.
第一步：冷兵器之纸笔，没有什么比这个更方便了：
第二步：构思出来以后，用SketchUp进行细化：
第三步：根据SketchUp的参数，做CAD去订亚克力机箱：
CAD图交付的时候，得留意一下是不是有双线的问题，因为如果存在双线，激光头会走两次，那个位置会明显缝隙大。图纸分层做好一些，让卖家做的事情少一些，出现故障的几率就会低一些。
制作
机箱的亚克力到货以前，先来改造一下原来的服务器主板，是HP的DL170e G6主板。为什么家用的东西要选服务器主板？主要有2个因素，一个是支持硬件的远控，另一方面是为了ECC内存和主板元件的排布设计，比较容易设计散热风路。
电源也打开看看有没有什么要加的，已经很好了，该有的都有，不过里面有三个大散热片直接靠在了电源的两侧，所以它可能壳会发热，亚克力时间长了可能会变形，所以在下面准备垫一个铁板，两边也空出来位置留给风流过：
这个风扇有点吵，是滚珠轴承的风扇，得给它换掉。要静音的话不能选滚珠轴承的风扇，我选的是建准的磁悬浮风扇，只有风噪没有轴承声音，具体可以去建准的网站去找合适的风扇，各种型号的都有。在这个小机箱里比较重要的是风压，需要足够的风压才能让风贯穿机箱。然后最好选PWM调速的风扇，带蓝色的线的那种，因为电压控制转速如果太低容易让风扇直接停转了，PWM就没有这个问题，Arduino也非常好控制，一行命令就可以实现了。
硬盘的读写灯准备放在面板上来，主板上的RPC Connector接脚定义实在是没有找到，只好从硬盘下手。硬盘的读写灯是第11引脚，虽然不是标准，但是大部分牌子都支持。文档上写这个接脚不能直接驱动LED，需要外围电路。可以先用这个方法试试看是不是可用先：

确定了PIN11可用，再做电路，我用了第二个，BC557：
焊接一个接口把PIN11引出来：
电源和主板的铁壳需要紧密合体，拆下主板在它的铁板上打沉孔，特别注意要清理好铁屑：
然后在电源的壳上攻丝：
拿镀锌板给电源旁边空出来的地方加了个挡片，保证风是从电源内部流过去：
上面图中，开孔的位置留给电源插座，又是得攻丝：
铁板顺便做了个硬盘架~铁皮很硬，相比铝板的好处是，可以经得住2次弯折，铝的只能一次定型，再弯就会断了。。。
里面的是2.5mm厚的EVA泡棉胶带，防震降噪。我肯定不会说这个胶带其实是因为没弄好尺寸，缝隙太大了没办法只好拿泡棉补。
亚！克！力！到货啦！很兴奋因为第一次弄亚克力：
用亚克力给大赛赞助的Arduino Mega做一个妥妥的架子：
已经接了一部分线上去，先测试看看~
万万没想到，万万没想到，亚克力粘接是这么痛苦。。。卖家说，我们手工费可贵啊。我说好吧那我回来自己粘。胶水是无影胶，UV固化的，需要在太阳下晒。一直阴天就算了，关键是胶水流的到处都是，很无奈啊，很尴尬啊，很丑陋啊，怎办，硬晒吧，多少有点紫外线吧。我晒了2天，胶还是粘的。同志们，专业的事情还是交给专业的人去做吧，让卖家把壳粘好再发货啊！
上面我原来以为是指纹，然而并不是！是胶纹！擦不掉的！
痛苦的亚克力先去晾着了，做一下硬盘灯的电路，焊的再丑良心也都不会痛。接头部分用手工暴力压线：
已经越来越乱了。。。每次都这么乱，搞的很专业似的，其实没有多少功能啊？
测试一下屏幕，屏幕用热熔胶大法直接黏在亚克力的另外一个内壳上了：
串口屏，省事，不用控制像素点了，直接画线、写字，很开心~
这么乱千万别被什么东西给挂到，再插回去可就难了。。。
各种混乱的线之电量模块：
电量模块其实淘宝有做好的带屏幕的模块，直接接上就可以了省事极了。但是为了逼格。。。
感应的线圈要避免干扰，单独给它准备了一房一厅：
把这一大堆线弄整齐是大难题之一，足足折腾了半个晚上：
Arduino这边就好办了，扎带大法：
1366的老平台，北桥很热很热，原来服务器的风扇可以提供比较高的风量和风压给它散热，但是为了控制噪音，风量没有那么大，所以需要单独的散热风扇，用导热硅胶加铁板直接黏住：
临近比赛结束的日子了，亚克力胶还没干。。。熬啊熬啊，终于出太阳了！
赶紧晒啊！别人都是晒衣服晒被子，我晒亚克力：
工具也晒一下：
花花也晒一下：
感谢老天爷，胶总算是干了。。。给底壳装铁板：
1mm厚的镀锌板，卖家切的尺寸这个准确啊：
硬盘部分加避震泡棉胶带：
感谢媳妇容忍我这一地东西，我自己看着都闹心：
最爱之一当然得出镜一下：
开始总装啦：
屏幕后面的线整理好，热熔胶大法：
Arduino部分的线也整理好，扎带大法：
前面的线也弄好了：
给底壳加上脚，6mm厚的泡棉胶带：
打印面板的标签，挖洞简直要崩溃，好在勉强还可以用：
当天组装好已经半夜了，开机起来，透过亚克力，哇奥，美不胜收：
星星点点：
里面好像一个宫殿：
白天再看看：
这个位置反光实在是太严重了。。。
再来：
Arduino安静的在下面：
开机，用光线感应控制背光亮度，屏幕下面一点用一片铝箔胶带感应触摸开关屏幕背光：
前面的9cm风扇，型号PSD1209PLV2-A，建准的编号很好认，1209表示12v 9cm，后面的V2，V代表磁悬浮轴承，如果是B是滚珠轴承不能选，2代表转速，U是ultra最高，1是高，2是中等。实际上这个风扇在1500转以下，深夜半米远几乎是零噪音，但是也可以转上4000暴力起来，也是只有风噪，强烈推荐建准的磁悬浮风扇用在家里的设备。
后面的插座，给Arduino的供电从电源的12v黄线引出来，电源的5v给屏幕，3.3v给其他模块，然后和Arduino的GND连在一起：
终于完工，接下来要装系统，让它开始上岗工作了，每天都是美好的一天！

会CAD果然也是一大优势
被逼无奈。。。现在订点什么都是激光切割，都得CAD图纸。。 机器开始服役，发现一些问题，就是原来源码里，风扇的控制不够连续，例如CPU从42上升到43度，风扇因为提速，声音变化比较突兀，夜深人静工作的时候，会被转移注意力。所以修改了下源码，把风扇的速度变化的时候过度的更柔和，用最近10次温度的移动平均来做控制。
新的代码：

const int TEMP_AVG_CYCLE = 10;
int tempCpuAvg;
int tempNorthAvg;
long tempCpuAvgTotal;
long tempNorthAvgTotal;
int avgIndex = 0;
loop函数中PWM部分：
// pwm
tempCpuAvgTotal = 0;
tempNorthAvgTotal = 0;
tempCpuAvg = max(tempCpu1, tempCpu2) * 100;
tempNorthAvg = tempNorth * 100;
avgIndex++;
if (avgIndex >= TEMP_AVG_CYCLE) {
avgIndex = 0;
}
for ( int i = 0; i < TEMP_AVG_CYCLE; ++i ) {
tempCpuAvgTotal += tempCpuAvg;
tempNorthAvgTotal += tempNorthAvg;
}
fanPwmMaster = map2(tempCpuAvgTotal / TEMP_AVG_CYCLE, TEMP_CPU_START, TEMP_CPU_MAX, 0, 254);
fanPwmNorth = map2(tempNorthAvgTotal / TEMP_AVG_CYCLE, TEMP_NORTH_START, TEMP_NORTH_MAX, 0, 254);
if (fanPwmMaster != fanPwmMaster_pre) {
analogWrite(PIN_MASTERFAN_PWM, fanPwmMaster);
//analogWrite(PIN_MASTERFAN2_PWM, fanPwmMaster);
