<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;"><span style="color: #95a5a6; font-size: 14px;"><img src="//image.lceda.cn/pullimage/pviI6hCuWyf36BPq68eBsLqdRylEcVgYFIspISNw.jpeg" alt="" width="800" height="475"></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;">升级部分:</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;">1、屏幕升级为2.0寸高清彩屏,可以显示更多的信息。</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;">2、支持外部独立供电或者被测电源供电,通过开关切换。使用外部供电时精度更高且支持更低的电压。</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;">3、按键换为拨轮开关,手感更好。</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;">增加部分:</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;">1、增加PD协议芯片,通过按键触发,支持协议查看以及PD诱骗。</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;">2、增加纹波放大电路,支持电源纹波查看。</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;">3、设置8P接口,以后支持外接电子负载、数控电源等设备。</p>
<h4 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;">硬件组成:</h4>
<p>本项目的组成比较多,从上到下分别是屏幕、核心控制板、接口板、底板。</p>
<p>核心控制板:</p>
<p>用于连接屏幕,上有单片机、拨轮开关、烧录接口等:</p>
<p>上有AT24CXX芯片,用于存储系统设置。</p>
<p>单片机可与独立供电接口连接电脑,通过串口查看电压电流值。以后尝试开发上位机软件。</p>

<p><img src="//image.lceda.cn/pullimage/K3vDZxZHi5QeDtZHQddXXiKOjxQCfy6hPL0qkWs1.png" alt="" width="797" height="487"></p>
<p> </p>
<p>接口板:</p>
<p>上有各种接口、INA226电路、降压电路、诱骗电路、纹波放大电路:</p>
<p>纹波放大电路放大6倍,可查看500mVpp内的纹波。</p>
<p>本接口板通过10p FPC排线与核心控制板相连。</p>
<p><img src="//image.lceda.cn/pullimage/wwa6tFYmGpOnx7Yn2QU3b4dBTABZe20YAkv3VWUo.png" alt="" width="797" height="470"></p>

<p>详细电路请到EDA查看工程。</p>
<p> </p>
<p>我觉得这个8P接口是本项目最大的升级以及升级空间:</p>
<p><img src="//image.lceda.cn/pullimage/RgHk4xcgg7dkv1qNmGUVZQiRYlA46eWyW8LdHmqn.png" alt="" width="438" height="295"></p>
<p>项目用到的2.0寸彩屏以及单片机的强大运算力如果仅仅用来功率计上我感觉还是有点大材小用的,于是我留出这个6P接口,将两个IO口、一个5V供电。一个IIC接口引出来,未来可以不断外接设备进行升级:</p>
<p>1、接电子负载,本功率计用作查看实时功率和控制电子负载</p>
<p>2、接热成像模块,本模块用于读取热成像数据,并显示在高清彩屏上</p>
<p>3、接数控电源,本功率计用作查看实时电压并控制数控电源输出</p>
<p>等等等</p>
<p> </p>
