一．项目介绍
油罐车数据采集，由于油罐车属于危险运输车辆，所以加强对油罐车数据监控可以防范事故的发生，本次通过TencentOS Tiny系统,内部的MQTT协议，对采集到的数据进行上传至腾讯云平台，通过腾讯连连即可实时看到数据信息。目前只是设计了罐车测的部分数据的采集上传，主要有GPS数据，对GPS中数据解析，如得到经纬度数据，速度信息。对压力传感器（4-20ma）的电流进行采集，光照度，温湿度数据进行采集，。
二．项目整体架构
整体就是这样的，使用的数据接口都是板子上的一个E53拓展接口，使用了GPIO和ADC，光照度和温湿度都是采用了一个IIC接口，GPS数据只用到了串口5的接收数据。
三．硬件组成
1. IMXRT1062
首先最主要的就是这款TencentOS Tiny AIoT开发套件，其使用了NXP的跨界处理器，IMXRT1062。其外部接口很丰富，除了上面的E53接口，其还有摄像头接口，音频接口,预留ESP8266接口，还有一个RGB转HDMI接口，同时还有PCI-e Module,可以外接模块，此款处理器也是可以跑图像识别的处理算法。
2.压力变送器
压力传感器，罐车一般可以使用4-20ma输出的，这样采集简单，同时4-20ma也不会达到易燃物的闪点。本次就是做了ADC功能，采集数据上传，当然我们外界电路，可以检测电流，换算压力，同时4ma可以帮助我们检测断线问题。
3.温湿度传感器
温湿度传感器，本次采用的是SHT20模块，通过和光照度传感器一致接口进行读数。
4.GPS模块
GPS模块采用的是Air530模块，其数据是自己回传的，一秒一次这样的。同时模块直接就包含了天线。我们通过GPS模块可以获得当前车辆位置信息，行驶速度信息等。
5. 未使用的，后期可以添加1. (已添加显示屏)
未使用到LCD，实际这几个数据通过LCD最方便获取，由于LVGL移植一致没通过所以本次先不用LCD显示了，所有数据我通过串口也输出显示了下。后期学习下别人的，可以添加到其中来。
昨天通知进决赛了，所以决定修改下屏幕，试着让显示屏亮起来，本次还是通过LVGL的移植。先看下效果。
目前创建了几个仪表，目前通过显示屏直接显示获得的数据，还是很清晰的，其中加入了温度湿度，压力，速度的显示。同时经纬度也是放在上面进行了显示。
四．项目中代码介绍以及测试结果
首先是在代码中初始化了三个任务，一个是MQTT数据上传和解析，一个用来读取ADC获取的值，还有一个是定时的解析串口收到的GPS数据。

}我在其基础上增加了一个SHT20温湿度模块，上面就是获取模块传感器的值。
温湿度和光照度数据。可以看到和米家的对比也基本是一致的。

}
}ADC部分代码。12位的ADC，我发现其值有所跳动。
GPS部分，我用了定时器获取其接收的数据，并通过NMEA开源的代码进行解析的。
这是GPS解析出的数据，和上位机中的数据是一致的。
LVGL的显示任务
目前可以使用官方的设计器来进行设计，最终导出的话，最新版本可以支持Keil了。所以还是很方便的。

这是最重要的一个文件了。他是任务的显示，同时对几个label进行修改的函数。
四.硬件整体
五．腾讯连连界面功能
这是我在腾讯云平台上创建的，可以用来调试，信息，同时上一步中可以生成腾讯连连的面板，和APP，这些就可以自己二次开发的。
这里我还是使用最原始的，没有改动的面板。
六．总结
本次的TencentOS Tiny AIoT应用创新大赛，让我接触到了TencentOS Tiny系统，学习这款系统，暂时还未从移植开始，因为本次官方所给的移植案例也是很丰富的，自己基本只需要修改下基本就能使用起来，但从其修改的代码上看，学习起来应该也很容易，后期希望通过自己移植到别的板子来继续学习。本次大赛提供的硬件也是很强大的，基本把MCU能做到的都弄好的，也看到了许多人移植图像处理，声音处理的算法还是很厉害的，希望后期基于这样一个平台接着深入的学习这款开发板。
