pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"> </p> <h2 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;">一、各模块功能介绍</h2> <p></p><hr class="horizontal-splitline normal-bold-2"><h2 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.主控</h2> <p>  <span style="font-size:18px;">为了能够在不连接电源的情况下提高续航,</span><span style="font-size:18px;">采用低功耗的N32L403KBQ7主控,主要的作用有:收集数据并处理,处理图像,发送数据给ESP8266,检测电池电量。<strong>切记!未引出BOOT0,只能通过SWD下载。</strong></span></p> <p> </p> <h2><span style="font-size:18px;"><span style="font-size:24px;">2.</span><span style="font-size:24px;">土壤湿度模块</span></span></h2> <p><span style="font-size:18px;">  使用优信家的土壤湿度模块,建议买沉金款的,普通款在高湿度环境下容易生锈,导致测量不准确等问题,因为是通过接触土壤的方式来检测,所以必须要插在土壤比较紧实的地方,并且滴箭(插入土壤里的水管)和土壤湿度模块必须相近,否则会导致水分输入过多的情况。</span></p> <p><img src="//image.lceda.cn/pullimage/QCoNHmfN6cFF3qb8u23ckwZP4JZqwsxEEJzCupnA.png" alt="" width="351" height="210"></p> <h2>3.温湿度模块</h2> <p><span style="font-size:18px;">  SHT30是一个比较常用的温湿度模块,尽管可以使用像DHT22这样的单总线通信模块,但是考虑体积问题,所以弃用此方案。此外SHT30具有功耗低,反应快,抗干扰能力强的优点。</span></p> <p><img src="//image.lceda.cn/pullimage/fReqt95BJDDB3uBnXLKdLNfXfKZm0TrHLvWclrw8.png" alt="" width="196" height="179"></p> <h2><span style="font-size:24px;">4.无线模块</span></h2> <p><span style="font-size:24px;">  <span style="font-size:18px;">本次无线和联网设备采用老朋友ESP8266,原本方案是采用同频率下功耗更低的ESP32-C3作为联网设备,MCU通过串口发送数据给ESP8266,ESP8266再通过MQTT向设备端发送数据,且终端也可发送信息给ESP8266,ESP8266再发给主控,进行环境参数设置,或者产生相应的动作。</span></span></p> <h2><img src="//image.lceda.cn/pullimage/9CjqoTr4DeTOSz731PbaK04mMvgZI7fGKWj3xMbh.png" alt="" width="325" height="242"></h2> <h2>5.光线传感器模块</h2> <p><span style="font-size:18px;">  采用BH1750,这个是帮别的学院的同学进行研究,光照对于植物对土壤湿度需求影响的研究(我负责的部分),但是被弃用了,而且放在背面,对于光照的敏感度太低。相关驱动代码已写好,有需要的同学自行领取~</span></p> <p> </p> <h2><span style="font-size:24px;">6.拨轮(按键控制)</span></h2> <p><span style="font-size:18px;">  拨轮相对于其他按键来说,拥有比较高的交互性,并且相对美观,已适配长按和短按驱动。</span></p> <p><img src="//image.lceda.cn/pullimage/42ptstSOVUYQFsavtNQnB8BVcufnmgzA6RslEMnv.png" alt="" width="334" height="293"></p> <h2>7.电源管理及充电模块</h2> <p><span style="font-size:18px;">  采用了一颗pmos管进行电源管理,当USB没有电源(VBUS)输入时,通过一颗弱下拉电阻,使得栅极呈低电平,此时DS导通,使用锂电池供电,当有USB电源提供时,VBUS会通过一颗肖特基二极管,给系统供电,此时DS断开,使得在充电的同时也可以给系统供电,若听的不是很明白,可以去看一下<a href="https://www.bilibili.com/video/BV1Na411h7tU?spm_id_from=333.999.0.0&vd_source=a1e9502e385d1bb03fa3ea7d653e93a3" target="_blank">工科男孙老师的视频</a>。充电部分采用锂电池电源管理芯片,LTC4054是TP4054的加强版(?),功能和TP4054差不多,不再赘述。</span></p> <p><img src="//image.lceda.cn/pullimage/ao409c4aid26BKqYHqHhMnT2ALL7KxB2EY1ReoCC.png" alt="" width="361" height="273"></p> <h2>8.水泵</h2> <p>  <span style="font-size:18px;">就普通的3V迷你水泵,只能说能用吧。。。。</span></p> <p><img src="//image.lceda.cn/pullimage/Gy0LU4OyjWRkg7Ikheuu84j9oZSEOQNshUBIAHy6.png" alt="" width="299" height="203"></p> <h2><span style="font-size:24px;">9.固定部分</span></h2> <p><span style="font-size:24px;">  <span style="font-size:18px;">焊接铜螺母</span></span></p> <h1 class="paragraph

采用两颗AMS1117分别给ESP8266和MCU及设备供电,采用星型连接,分开供电,避免ESP8266在高功耗时AMS1117发热严重,导致温度测量不准确。电池供电使用RC滤波,有效减少低频噪声。充放电共存在上面已有说明。</span></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto

style="font-size:18px;">本项目采用了写Flash的方式进行数据的存储,主要是设定上的数据,如马达的转速,设定浇水的土壤湿度,将其存储在第63页,从第0位开始,高8位是记录马达转速,低8位是记录浇水的土壤湿度。</span></p> <p><span style="font-size:24px;"><strong>7.延时函数</strong></span></p> <p><span style="font-size:18px;">采用两个通用定时器TIM6和TIM7,想着反正用不到,就用来计时了,分别进行ms级和us级的延时,在系统开始时必须调用一次,否则第一个延时函数将失效。</span></p> <p><span style="font-size:24px;"><strong>8.按键</strong></span></p> <p> <span style="font-size:18px;">实现了长短按的功能,但是我这项目只用到短按,思路是当检测到按键按下,进入while循环,此时对应按键的数值++,当达到阀值(长按的时间)或者按键不再按下的时候跳出,循环内有判断,会将长按的标志位置位,再进行判断是哪个按键按下,以及长短按的情况</span></p> <p> </p> <h1 class="paragraph
