嵌入式項目：基于QT與Hi3861的物聯網智能大棚集成控制系統

關鍵詞：MQTT、物聯網、QT、網絡連接、遠程控制

一、系統概述

本系統是一套完整的智能大棚監控解決方案，由兩部分構成：

基于Hi3861的嵌入式硬件系統（負責環境數據采集和設備控制）
基于Qt開發的跨平臺控制軟件（提供可視化界面和遠程控制）

該系統實現對大棚環境的全方位監控：

??環境監測系統??：實時檢測溫度、濕度、光照強度、CO?濃度
??安防系統??：人體檢測報警（PIR傳感器）
??執行設備??：LED補光燈控制、通風風扇控制
??雙模控制??：手動控制/自動智能控制模式
??遠程監控??：實時數據面板 + 三態環境狀態指示
??異常處理??：臨界值提醒與自動執行保護策略

二、Qt控制界面設計亮點

1. 布局結構(用戶登錄界面和系統控制界面)

登錄界面

2. 動態數據可視化功能

??環境數據卡片設計：??

QWidget* Widget::createDataCard(const QString& title, const QString& unit, const QColor& color)
{// 創建帶有彩色邊框的數據卡片// 包含標題、實時數值、單位和趨勢指示器
}

??趨勢變化可視化：?

由于博主的QT版本過低，部分模塊及代碼無法兼容，所以無法通過繪制溫濕度、光照強度的折線圖觀察環境數據的具體趨勢，采用箭頭指示?的方式作為系統數據趨勢的指示器，當檢測到此次數據較上一次采集數據高時箭頭指向↑，以此類推。

// 更新趨勢指示器（上升↑、下降↓、穩定→）
if (value > prevValue) {trendLabel->setText("↑");trendLabel->setStyleSheet("color: red;");
} else if (value < prevValue) {trendLabel->setText("↓");trendLabel->setStyleSheet("color: blue;");
} else {trendLabel->setText("→");
}

???3. 三態預警系統??

我們創新性地采用三色指示燈直觀展示環境狀態（正常/臨界/異常），避免單一閾值判斷的局限性：

void Widget::updateStatusIndicator(QWidget* indicator, double value, double min, double max) {QLabel *light = indicator->findChild<QLabel*>("statusLight");if (!light) return;// 正常范圍：顯示綠色if (value >= min && value <= max) {light->setStyleSheet("border-radius: 15px; background-color: #4CAF50;");} // 臨界范圍：顯示黃色（預留±5緩沖區間）else if ((value >= min-5 && value < min) || (value > max && value <= max+5)) {light->setStyleSheet("border-radius: 15px; background-color: #FFC107;");} // 危險范圍：顯示紅色else {light->setStyleSheet("border-radius: 15px; background-color: #F44336;");}
}

應用場景示例：

溫度預警：20-28℃正常（綠）｜15-19℃或29-33℃警告（黃）｜＜15℃或＞33℃危險（紅）
該設計解決了傳統二元警報頻繁誤報問題，大幅提升監控準確性

??4. 人體檢測可視化??

采用動態指示燈+狀態文字雙重提示：

// 提取人體監測數據bool humanDetected = jsonObj.contains("HumanSensor") ? jsonObj["HumanSensor"].toBool() : false;// 更新人體監測指示燈if (humanDetected) {humanMonitorLabel->setStyleSheet("border-radius: 15px; background-color: green;");humanMonitorStatus->setText("有人");} else {humanMonitorLabel->setStyleSheet("border-radius: 15px; background-color: red;");humanMonitorStatus->setText("無人");}

安防聯動設計：

檢測到人員時觸發警報（可以嘗試添加人臉識別，制作檢測抓拍記錄功能）
夜間模式下自動開啟補光燈輔助監控

???三、ThingsCloud云平臺

?1.設備詳情

新建設備智能大棚，添加大棚燈、風機、溫濕度、人體監測等部分，需要注意的是由QT控制的部分(燈、風機、警報)需要將屬性設置為云端下發屬性，QT接收的溫濕度、光照強度、CO2等設置為設備上報屬性

2.設備看板

3.手機端云平臺

在ThingsCloud云平臺創建自己的UI界面，注意添加對應組件的屬性，保存后在掃描用戶應用中的微信小程序二維碼，登錄的手機端云平臺界面就是電腦端創建的UI界面，該界面與電腦端界面操作同步。

4.MQTT通信效果

我們在MQTTX創建設備連接，連接云平臺設備，在發送如下字符（設備上報）后發現看板組件確實安裝發送的溫濕度數據配置，同時在看板中打開燈，云端下發了如下字符，證明MQTT通信成功，可以連接。

四、雙模式控制機制?

??1. 手動模式

用戶可直接點擊控件按鈕，系統實時反饋設備狀態：

void Widget::toggleLight1() {if (!autoMode) { // 僅在手動模式響應light1On = !light1On;light1Button->setText(light1On ? "開" : "關");sendData(light1On ? "{\"light0\":true}" : "{\"light0\":false}");}
}

點擊按鍵后，QT根據按鍵向開發板發送固定字符，開發板通過接收的字符進行判斷，控制部分外設進行特定功能。

??2. 自動模式 ?

動態響應環境變化，用戶在自動模式下無法直接操作按鍵，由系統自行控制，同時系統日志顯示切換到自動模式。

void Widget::parseEnvironmentData(const QByteArray &data) {if (autoMode) {// 溫度>26°C開啟風扇，<25°C關閉（滯回控制防抖動）if (temp > 26.0 && !fanOn) sendControlCommand(FAN_ON); else if (temp <= 25.0 && fanOn) sendControlCommand(FAN_OFF);// 光照<80Lux開燈，>90Lux關燈if (lightIntensity < 80 && !light1On) sendControlCommand(LIGHT_ON);else if (lightIntensity >= 90 && light1On) sendControlCommand(LIGHT_OFF);// 人員檢測聯動報警if (humanDetected) sendControlCommand(ALARM_ON);else if (alarmOn) sendControlCommand(ALARM_OFF);}
}

策略優勢：

滯回區間設計：防止溫度波動導致風扇頻繁啟停
分級響應：不同設備采用獨立閾值策略

??五、通信與算法優化實踐??

??1. 高效UDP通信協議?

初始化udp套接字，以及開發板IP地址。注：確保電腦和開發板要連在同一WiFi熱點下，通過串口查找開發板設備IP地址，在QT代碼中設為連接目標，確保端口號與開發板程序設定的端口號一致(此處設置為9000，設備IP地址為192.168.34.8).?

// 初始化UDPudpSocket = new QUdpSocket(this);if (!udpSocket->bind(QHostAddress::Any, 9000)) {QMessageBox::critical(this, "初始化錯誤", "UDP套接字綁定失敗，請檢查端口是否被占用");} else {connect(udpSocket, SIGNAL(readyRead()), this, SLOT(recvData()));}
}

??2. 核心算法優化實例?

解析JSON數據：溫濕度，光照，CO2，人體監測狀態，判斷是否為自動模式，根據解析的數據進行面板顯示和狀態指示燈顯示。?

void Widget::parseEnvironmentData(const QByteArray &data)
{QJsonParseError jsonError;QJsonDocument jsonDoc = QJsonDocument::fromJson(data, &jsonError);if (jsonError.error == QJsonParseError::NoError && jsonDoc.isObject()) {QJsonObject jsonObj = jsonDoc.object();// 提取溫度數據（使用0作為默認值）double temperature = jsonObj.contains("Temp") ? jsonObj["Temp"].toDouble() : 0.0;// 更新溫度數據卡片if (tempCard) {QLabel *tempValueLabel = tempCard->findChild<QLabel*>("valueLabel");if (tempValueLabel) {tempValueLabel->setText(QString::number(temperature, 'f', 1));// 更新趨勢指示器QLabel *tempTrendLabel = tempCard->findChild<QLabel*>("trendLabel");if (tempTrendLabel) {if (temperature > prevTemp) {tempTrendLabel->setText("↑");tempTrendLabel->setStyleSheet("color: red; font-size: 24px;");} else if (temperature < prevTemp) {tempTrendLabel->setText("↓");tempTrendLabel->setStyleSheet("color: blue; font-size: 24px;");} else {tempTrendLabel->setText("→");tempTrendLabel->setStyleSheet("color: gray; font-size: 24px;");}prevTemp = temperature;}}}// 提取濕度數據double humidity = jsonObj.contains("Humi") ? jsonObj["Humi"].toDouble() : 0.0;if (humCard) {QLabel *humValueLabel = humCard->findChild<QLabel*>("valueLabel");if (humValueLabel) {humValueLabel->setText(QString::number(humidity, 'f', 0));// 更新趨勢指示器QLabel *humTrendLabel = humCard->findChild<QLabel*>("trendLabel");if (humTrendLabel) {if (humidity > prevHum) {humTrendLabel->setText("↑");humTrendLabel->setStyleSheet("color: red; font-size: 24px;");} else if (humidity < prevHum) {humTrendLabel->setText("↓");humTrendLabel->setStyleSheet("color: blue; font-size: 24px;");} else {humTrendLabel->setText("→");humTrendLabel->setStyleSheet("color: gray; font-size: 24px;");}prevHum = humidity;}}}// 提取CO?數據int co2 = jsonObj.contains("CO2") ? jsonObj["CO2"].toInt() : 0;if (co2Card) {QLabel *co2ValueLabel = co2Card->findChild<QLabel*>("valueLabel");if (co2ValueLabel) {co2ValueLabel->setText(QString::number(co2));// 更新趨勢指示器QLabel *co2TrendLabel = co2Card->findChild<QLabel*>("trendLabel");if (co2TrendLabel) {if (co2 > prevCO2) {co2TrendLabel->setText("↑");co2TrendLabel->setStyleSheet("color: red; font-size: 24px;");} else if (co2 < prevCO2) {co2TrendLabel->setText("↓");co2TrendLabel->setStyleSheet("color: blue; font-size: 24px;");} else {co2TrendLabel->setText("→");co2TrendLabel->setStyleSheet("color: gray; font-size: 24px;");}prevCO2 = co2;}}}// 提取光照強度數據int lightIntensity = jsonObj.contains("lumen") ? jsonObj["lumen"].toInt() : 0;if (lightCard) {QLabel *lightValueLabel = lightCard->findChild<QLabel*>("valueLabel");if (lightValueLabel) {lightValueLabel->setText(QString::number(lightIntensity));// 更新趨勢指示器QLabel *lightTrendLabel = lightCard->findChild<QLabel*>("trendLabel");if (lightTrendLabel) {if (lightIntensity > prevLight) {lightTrendLabel->setText("↑");lightTrendLabel->setStyleSheet("color: red; font-size: 24px;");} else if (lightIntensity < prevLight) {lightTrendLabel->setText("↓");lightTrendLabel->setStyleSheet("color: blue; font-size: 24px;");} else {lightTrendLabel->setText("→");lightTrendLabel->setStyleSheet("color: gray; font-size: 24px;");}prevLight = lightIntensity;}}}// 更新狀態指示器updateStatusIndicator(tempStatus, temperature, 20, 28);updateStatusIndicator(humStatus, humidity, 40, 60);updateStatusIndicator(co2Status, co2, 0, 800);updateStatusIndicator(lightStatus, lightIntensity, 80, 100);// 提取人體監測數據bool humanDetected = jsonObj.contains("HumanSensor") ? jsonObj["HumanSensor"].toBool() : false;// 更新人體監測指示燈if (humanDetected) {humanMonitorLabel->setStyleSheet("border-radius: 15px; background-color: green;");humanMonitorStatus->setText("有人");} else {humanMonitorLabel->setStyleSheet("border-radius: 15px; background-color: red;");humanMonitorStatus->setText("無人");}// 更新溫度數據用于存儲if (!temperatureData.isEmpty()) {temperatureData.pop_front();temperatureData.append(temperature);}// 如果是自動模式，執行自動控制邏輯if (autoMode) {// 溫度高于26度時開啟風扇if (temperature > 26.0 && !fanOn) {sendData("{\"Fan0\":true}");fanOn = true;fanButton->setText("開");fanButton->setChecked(true);}// 溫度低于25度時關閉風扇else if (temperature <= 25.0 && fanOn) {sendData("{\"Fan0\":false}");fanOn = false;fanButton->setText("關");fanButton->setChecked(false);}// 檢測到有人時開啟報警if (humanDetected && !alarmOn) {sendData("{\"Alarm\":true}");alarmOn = true;alarmButton->setText("開");alarmButton->setChecked(true);}// 無人時關閉報警else if (!humanDetected && alarmOn) {sendData("{\"Alarm\":false}");alarmOn = false;alarmButton->setText("關");alarmButton->setChecked(false);}// 光照強度小于100時開啟燈1if (lightIntensity < 80 && !light1On) {sendData("{\"light0\":true}");light1On = true;light1Button->setText("開");light1Button->setChecked(true);}// 光照強度大于150時關閉燈1else if (lightIntensity >= 90 && light1On) {sendData("{\"light0\":false}");light1On = false;light1Button->setText("關");light1Button->setChecked(false);}}}
}

??七、應用價值與創新突破??
?

1. 技術創新突破點??

??雙模無縫切換??：手動操作可臨時覆蓋自動策略，滿足緊急干預需求
??設備聯動引擎??：實現"光照不足→自動補光+溫度調節"的復合響應
??設備聯動??：采用QT控制開發板時云平臺圖標隨QT同步變化（前提是在云平臺將設備組件屬性改為共享模式）?
??QT界面：采用分塊布局，左側為控制面板，右側為監測面板，布局合理
?數據分析：舍棄折線圖形式，采用對比數據顯示箭頭表示數據變化趨勢、三態指示燈表示數據異常情況?

?八、寫在最后

1. 注意事項

a. 編寫主程序時需要注意變量的宏定義和引用問題，例如將UDP上傳放在按鍵中斷中，在主程序的任務中接收溫濕度，需要確定變量類型。

b. 值得注意的是，在使用云平臺控制開發板時我們打開MQTTX軟件觀察，發現MQTTX反復斷開后重連，起初我們認為是網絡連接不穩定，后來排除后發現云平臺每次只能和MQTTX或者開發板其一通信，兩者同時使用會產生沖突。

?在整個項目中出現了各個部分的bug包括主程序中線程間的占用問題、網絡連接問題、QT的UDP通信問題，甚至在MQTT無法連接時進行各種排查，發現是博主的隊友云平臺賬號被封號。。。。但是最后的完成度還是非常高，有興趣的朋友可以嘗試使用其他外設，添加語音、攝像頭、人臉識別，甚至接入deepseek，都是可以嘗試的方向。
