基于高德MCP2.0的智能旅游攻略系统设计与实现
前言：旅游规划的技术革命
在数字化旅游时代，MCP2.0（Map-based Collaborative Planning）系统代表着旅游攻略技术的最新演进。作为对1.0版本的全面升级，MCP2.0通过深度整合高德地图API和智能算法，实现了从静态信息展示到动态智能规划的质的飞跃。本系统专为解决现代旅行者面临的三大核心痛点而设计：
- 信息过载：海量景点数据难以有效筛选和组织
- 规划低效：手动规划路线耗时费力且难以优化
- 实时应变：无法根据路况和突发情况动态调整行程

// 初始化高德地图
function initMap() {// 创建地图实例const map = new AMap.Map('map-container', {zoom: 12, // 初始缩放级别center: [116.397428, 39.90923], // 初始中心点（北京）viewMode: '3D' // 使用3D视图});// 添加控件map.addControl(new AMap.ControlBar({showZoomBar: true,showControlButton: true,position: {right: '10px',top: '10px'}}));return map;
}// 添加景点标记
function addScenicSpots(map, spots) {spots.forEach(spot => {const marker = new AMap.Marker({position: new AMap.LngLat(spot.lng, spot.lat),title: spot.name,content: `<div class="marker">${spot.name}</div>`,offset: new AMap.Pixel(-13, -30)});// 添加信息窗口marker.on('click', () => {const infoWindow = new AMap.InfoWindow({content: `<h3>${spot.name}</h3><p>${spot.description}</p><p>建议游玩时间: ${spot.recommendedTime}小时</p><p>门票: ${spot.ticketPrice || '免费'}</p>`,offset: new AMap.Pixel(0, -30)});infoWindow.open(map, marker.getPosition());});map.add(marker);});
}代码1：地图初始化和景点标记实现
3.2 高德地图APP集成
// 检查是否安装高德地图APP
function checkAMapInstalled() {return new Promise((resolve) => {if (navigator.userAgent.match(/(iPhone|iPod|iPad);?/i)) {const iframe = document.createElement('iframe');iframe.src = 'iosamap://';iframe.style.display = 'none';document.body.appendChild(iframe);setTimeout(() => {document.body.removeChild(iframe);resolve(true);}, 100);} else {const intent = 'androidamap://';try {window.location = intent;setTimeout(() => {resolve(document.hidden !== true);}, 100);} catch (e) {resolve(false);}}});
}// 打开高德地图APP并传递路线
async function openAMapWithRoute(route) {const isInstalled = await checkAMapInstalled();if (!isInstalled) {window.open('https://www.amap.com/');return;}const { origin, waypoints, destination } = route;let url;if (navigator.userAgent.match(/(iPhone|iPod|iPad);?/i)) {url = `iosamap://path?sourceApplication=旅游攻略&sid=BGVIS1&slat=${origin.lat}&slon=${origin.lng}&sname=起点`;waypoints.forEach((point, index) => {url += `&via${index + 1}Lat=${point.lat}&via${index + 1}Lon=${point.lng}&via${index + 1}Name=${point.name}`;});url += `&dlat=${destination.lat}&dlon=${destination.lng}&dname=${destination.name}&dev=0&t=0`;} else {url = `androidamap://route?sourceApplication=旅游攻略&sname=起点&slat=${origin.lat}&slon=${origin.lng}`;waypoints.forEach((point, index) => {url += `&via${index + 1}Name=${point.name}&via${index + 1}Lat=${point.lat}&via${index + 1}Lon=${point.lng}`;});url += `&dname=${destination.name}&dlat=${destination.lat}&dlon=${destination.lng}&dev=0&t=0`;}window.location.href = url;
}代码2：高德地图APP集成实现
3.3 智能行程规划算法
// 基于贪心算法的景点排序
function sortAttractions(attractions, startPoint, maxHoursPerDay) {const result = [];let currentDay = 1;let remainingHours = maxHoursPerDay;let currentPosition = startPoint;let dayAttractions = [];// 克隆景点数组避免修改原数组const remainingAttractions = [...attractions];while (remainingAttractions.length > 0) {// 找出距离当前位置最近的景点let nearestIndex = 0;let nearestDistance = calculateDistance(currentPosition,remainingAttractions[0].position);for (let i = 1; i < remainingAttractions.length; i++) {const distance = calculateDistance(currentPosition,remainingAttractions[i].position);if (distance < nearestDistance) {nearestDistance = distance;nearestIndex = i;}}const selectedAttraction = remainingAttractions[nearestIndex];// 检查是否还能加入当天的行程if (remainingHours >= selectedAttraction.timeRequired) {dayAttractions.push(selectedAttraction);remainingHours -= selectedAttraction.timeRequired;currentPosition = selectedAttraction.position;remainingAttractions.splice(nearestIndex, 1);} else {// 保存当天的行程，开始新的一天result.push({day: currentDay,attractions: [...dayAttractions],totalHours: maxHoursPerDay - remainingHours});currentDay++;remainingHours = maxHoursPerDay;dayAttractions = [];// 如果当前景点无法加入任何一天，则强制加入if (selectedAttraction.timeRequired > maxHoursPerDay) {dayAttractions.push(selectedAttraction);remainingHours = maxHoursPerDay - selectedAttraction.timeRequired;currentPosition = selectedAttraction.position;remainingAttractions.splice(nearestIndex, 1);}}}// 添加最后一天的行程if (dayAttractions.length > 0) {result.push({day: currentDay,attractions: [...dayAttractions],totalHours: maxHoursPerDay - remainingHours});}return result;
}// 计算两点之间的距离（简化版，实际应使用高德API）
function calculateDistance(point1, point2) {const R = 6371; // 地球半径(km)const dLat = (point2.lat - point1.lat) * Math.PI / 180;const dLon = (point2.lng - point1.lng) * Math.PI / 180;const a = Math.sin(dLat / 2) * Math.sin(dLat / 2) +Math.cos(point1.lat * Math.PI / 180) * Math.cos(point2.lat * Math.PI / 180) * Math.sin(dLon / 2) * Math.sin(dLon / 2);const c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a));return R * c;

4. 实时路况集成
4.1 实时路况获取与展示
// 获取实时路况信息
async function getTrafficInfo(map, path) {try {// 使用高德地图API获取路况const trafficLayer = new AMap.TileLayer.Traffic({zIndex: 10,opacity: 0.7,zooms: [7, 22]});trafficLayer.setMap(map);// 获取路径规划考虑实时路况const driving = new AMap.Driving({map: map,policy: AMap.DrivingPolicy.REAL_TRAFFIC, // 考虑实时路况showTraffic: true,hideMarkers: true});// 转换路径坐标格式const waypoints = path.slice(1, -1).map(point => ({lnglat: [point.lng, point.lat]}));// 执行路径规划driving.search([path[0].lng, path[0].lat],[path[path.length - 1].lng, path[path.length - 1].lat],{ waypoints },(status, result) => {if (status === 'complete') {console.log('路线规划完成', result);// 更新预计到达时间updateETA(result.routes[0]);} else {console.error('路线规划失败', result);}});} catch (error) {console.error('获取实时路况失败:', error);}
}// 更新预计到达时间
function updateETA(route) {const distance = route.distance; // 单位：米const duration = route.time; // 单位：秒const trafficCondition = getTrafficCondition(route.trafficStatus);// 显示在UI上document.getElementById('eta-distance').textContent = `${(distance / 1000).toFixed(1)} km`;document.getElementById('eta-time').textContent = `${Math.floor(duration / 3600)}小时${Math.floor((duration % 3600) / 60)}分钟`;document.getElementById('eta-traffic').textContent = trafficCondition;document.getElementById('eta-traffic').className = `traffic-${route.trafficStatus.toLowerCase()}`;
}// 根据交通状态代码获取描述
function getTrafficCondition(status) {const conditions = {'UNKNOWN': '路况未知','SMOOTH': '畅通','SLOW': '缓行','CONGESTED': '拥堵','BLOCKED': '严重拥堵'};return conditions[status] || '路况未知';
