鸿蒙跨设备经期健康管理系统：基于分布式数据的智能预测与协同提醒方案

一、系统架构设计

!https://example.com/harmonyos-cycle-arch.png

采用三层架构：
数据层：多终端历史数据收集与同步

分析层：分布式机器学习预测引擎

服务层：跨设备提醒与健康建议推送

二、核心模块实现
周期数据分析模块

// CycleAnalyzer.ts
import statistical from ‘@ohos.ai.statistical’;
import dateTime from ‘@ohos.dateTime’;

interface CycleRecord {
startDate: string; // YYYY-MM-DD
endDate: string;
symptoms?: string[];
flowLevel: 1 2
3; // 1-轻 2-中 3-重
interface PredictionResult {

nextPeriod: string;
fertileWindow: [string, string];
ovulationDay: string;
confidence: number;
export class CycleAnalyzer {

private predictor?: statistical.TimeSeriesPredictor;

async init() {
this.predictor = await statistical.createPredictor(‘menstrual_cycle’);
async predictNextCycle(records: CycleRecord[]): Promise<PredictionResult> {

const formattedData = this.formatTrainingData(records);
await this.predictor.train(formattedData);

const prediction = await this.predictor.predict({
  horizon: 3, // 预测未来3个周期
  frequency: 'monthly'
});

return {
  nextPeriod: this.formatDate(prediction.values[0]),
  fertileWindow: [
    this.formatDate(prediction.values[0] - 14),
    this.formatDate(prediction.values[0] - 10)
  ],
  ovulationDay: this.formatDate(prediction.values[0] - 12),
  confidence: prediction.confidence
};

private formatTrainingData(records: CycleRecord[]): statistical.TimeSeriesData {

return {
  timestamps: records.map(r => new Date(r.startDate).getTime()),
  values: records.map((r, i) => {
    const duration = dateTime.getDiffDays(
      new Date(r.startDate), 
      new Date(records[i > 0 ? i-1 : 0].startDate)
    );
    return duration;
  })
};

// 其他辅助方法…

分布式健康数据管理

// HealthDataSync.ts
import distributedData from ‘@ohos.data.distributedData’;

interface HealthRecord {
recordId: string;
type: ‘cycle’ ‘symptom’
‘mood’;
date: string;
deviceId: string;
data: Record<string, any>;
export class HealthDataSync {

private kvManager: distributedData.KVManager;
private kvStore: distributedData.KVStore;

async init() {
const context = getContext(this);
this.kvManager = distributedData.createKVManager({ context });

const options = {
  createIfMissing: true,
  encrypt: true,
  autoSync: true,
  kvStoreType: distributedData.KVStoreType.SINGLE_VERSION,
  securityLevel: distributedData.SecurityLevel.S2
};

this.kvStore = await this.kvManager.getKVStore('health_records', options);
this.setupDataListeners();

async addRecord(record: Omit<HealthRecord, ‘recordId’>): Promise<string> {

const recordId = record_${Date.now()};
const fullRecord = { ...record, recordId };

await this.kvStore.put(recordId, fullRecord);
return recordId;

async getCycleRecords(userId: string): Promise<CycleRecord[]> {

const entries = await this.kvStore.entries('record_');
return entries
  .filter(([_, v]) => v.type = 'cycle' && v.userId = userId)
  .map(([_, v]) => v.data as CycleRecord);

private setupDataListeners() {

this.kvStore.on('dataChange', distributedData.SubscribeType.SUBSCRIBE_TYPE_REMOTE, 
  (changes) => {
    changes.forEach(({ key, value }) => {
      if (key.startsWith('record_')) {
        this.handleRecordUpdate(value);

});

});

// 其他方法…

智能提醒服务

// ReminderService.ts
import notification from ‘@ohos.notification’;
import reminderAgent from ‘@ohos.reminderAgent’;

export class ReminderService {
async scheduleReminder(prediction: PredictionResult) {
const nextPeriodDate = new Date(prediction.nextPeriod);

// 提前3天提醒
const preReminder: reminderAgent.ReminderRequest = {
  reminderType: reminderAgent.ReminderType.CALENDAR,
  title: '经期即将开始',
  content: '根据预测您的经期将在3天后开始',
  scheduledTime: new Date(nextPeriodDate.setDate(nextPeriodDate.getDate() - 3)).getTime(),
  notificationId: 1
};

await reminderAgent.publishReminder(preReminder);

// 排卵期提醒
const ovulationReminder: reminderAgent.ReminderRequest = {
  reminderType: reminderAgent.ReminderType.CALENDAR,
  title: '排卵期提醒',
  content: '您的排卵期窗口已开始',
  scheduledTime: new Date(prediction.fertileWindow[0]).getTime(),
  notificationId: 2
};

await reminderAgent.publishReminder(ovulationReminder);

async cancelAllReminders() {

await reminderAgent.cancelAllReminders();

}

三、主页面实现（ArkUI）

// CycleTracker.ets
import { CycleAnalyzer } from ‘./CycleAnalyzer’;
import { HealthDataSync } from ‘./HealthDataSync’;
import { ReminderService } from ‘./ReminderService’;

@Entry
@Component
struct CycleTrackerApp {
@State records: CycleRecord[] = [];
@State prediction?: PredictionResult;
@State syncing: boolean = false;

private analyzer = new CycleAnalyzer();
private dataSync = new HealthDataSync();
private reminder = new ReminderService();

async aboutToAppear() {
await this.analyzer.init();
await this.dataSync.init();
this.loadRecords();
async loadRecords() {

this.syncing = true;
this.records = await this.dataSync.getCycleRecords('current_user');
this.syncing = false;

if (this.records.length >= 3) { // 至少需要3个周期数据
  this.prediction = await this.analyzer.predictNextCycle(this.records);
  await this.reminder.scheduleReminder(this.prediction);

}

async addNewRecord(record: Omit<CycleRecord, ‘startDate’ | ‘endDate’> & { date: string }) {
const cycleRecord: CycleRecord = {
startDate: record.date,
endDate: record.date, // 简化处理
flowLevel: record.flowLevel,
symptoms: record.symptoms
};

await this.dataSync.addRecord({
  type: 'cycle',
  date: record.date,
  deviceId: 'current_device',
  data: cycleRecord
});

this.loadRecords(); // 刷新数据

build() {

Column() {
  // 数据同步状态
  if (this.syncing) {
    ProgressBar()

// 周期日历视图

  CycleCalendar({
    records: this.records,
    prediction: this.prediction
  })
  
  // 预测结果展示
  if (this.prediction) {
    PredictionDisplay(this.prediction)

// 记录输入表单

  RecordInputForm({
    onSave: (record) => this.addNewRecord(record)
  })

}

@Component

struct CycleCalendar {
@Prop records: CycleRecord[];
@Prop prediction?: PredictionResult;

build() {
Grid() {
// 实现日历渲染逻辑
ForEach(this.getCalendarDays(), (day) => {
GridItem() {
CalendarDay({
day,
isPeriod: this.isPeriodDay(day),
isPredicted: this.isPredictedDay(day)
})
})

.columnsTemplate(‘1fr 1fr 1fr 1fr 1fr 1fr 1fr’)

.rowsGap(10)
.columnsGap(5)

// 其他方法…

@Component

struct PredictionDisplay {
@Prop prediction: PredictionResult;

build() {
Column() {
Text(下次经期预测: ${this.prediction.nextPeriod})
.fontSize(18)

  Text(排卵窗口: {this.prediction.fertileWindow[0]} 至 {this.prediction.fertileWindow[1]})
    .fontSize(16)
  
  Text(预测准确度: ${this.prediction.confidence.toFixed(1)}%)
    .fontSize(14)

}

四、跨设备协同关键实现
多设备数据融合

// 在HealthDataSync中添加
async syncFromAllDevices(userId: string) {
const devices = await this.getTrustedDevices();
const records = await Promise.all(
devices.map(device =>
this.getDeviceRecords(device.deviceId, userId)
)
);

return records.flat();
private async getDeviceRecords(deviceId: string, userId: string) {

try {
const remoteStore = await distributedData.getRemoteKVStore(
deviceId,
‘health_records’
);
const entries = await remoteStore.entries(‘record_’);
return entries
.filter(([, v]) => v.userId === userId)
.map(([, v]) => v);
catch (err) {

console.error(从设备${deviceId}获取数据失败:, err);
return [];

}

预测结果共享

// 在CycleAnalyzer中添加
async syncPrediction(userId: string, prediction: PredictionResult) {
const record: HealthRecord = {
recordId: prediction_${Date.now()},
type: ‘prediction’,
date: new Date().toISOString(),
deviceId: ‘current_device’,
data: prediction
};

await this.dataSync.addRecord(record);

分布式提醒设置

// 在ReminderService中添加
async syncReminders(userId: string, reminders: ReminderRequest[]) {
const devices = await deviceManager.getTrustedDeviceListSync();
await Promise.all(
devices.map(device =>
this.setDeviceReminders(device.deviceId, userId, reminders)
)
);
private async setDeviceReminders(deviceId: string, userId: string, reminders: ReminderRequest[]) {

try {
await distributedNotification.publish({
type: ‘set_reminders’,
targetDevice: deviceId,
parameters: { userId, reminders }
});
catch (err) {

console.error(同步提醒到设备${deviceId}失败:, err);

}

五、隐私与安全方案
数据加密存储

// 增强HealthDataSync初始化
const secureOptions = {
encrypt: true,
encryptAlg: ‘AES-GCM’,
encryptKey: this.generateEncryptionKey(userId),
kvStoreType: distributedData.KVStoreType.DEVICE_COLLABORATION
};

权限控制

// module.json5
“requestPermissions”: [
“name”: “ohos.permission.HEALTH_DATA_READ”,

"reason": "用于经期预测分析"

},
“name”: “ohos.permission.HEALTH_DATA_WRITE”,

"reason": "记录健康数据"

},
“name”: “ohos.permission.DISTRIBUTED_DATASYNC”,

"reason": "多设备数据同步"

]

六、性能优化方案
增量数据同步

// 在HealthDataSync中添加
async syncIncremental(userId: string, lastSync: number) {
const query = {
prefix: ‘record_’,
filters: [
field: ‘userId’, value: userId },

field: ‘timestamp’, op: ‘>’, value: lastSync }

};

return this.kvStore.query(query);

本地预测缓存

const predictionCache = new Map<string, PredictionResult>();

async getCachedPrediction(userId: string): Promise<PredictionResult | undefined> {
const cacheKey = ${userId}_prediction;
if (predictionCache.has(cacheKey)) {
return predictionCache.get(cacheKey);
const records = await this.dataSync.getCycleRecords(userId);

if (records.length < 3) return undefined;

const prediction = await this.analyzer.predictNextCycle(records);
predictionCache.set(cacheKey, prediction);
return prediction;

七、应用场景扩展
健康趋势分析

class HealthTrends {
async analyzeSymptomPatterns(userId: string) {
// 分析症状与周期的关联性
}

医疗报告生成

class MedicalReport {
async generateYearlyReport(userId: string) {
// 生成年度周期报告
}

智能生活方式建议

class LifestyleAdvisor {
async getDailyRecommendation(date: string) {
// 根据周期阶段提供建议
}

家庭健康共享

class FamilySharing {
async shareWithPartner(userId: string, partnerId: string) {
// 与伴侣共享特定健康数据
}

本系统充分利用HarmonyOS分布式能力，实现了：
多设备数据无缝同步：手机、手表、平板等设备数据自动聚合
